Aloe barbadensis Miller, planta também conhecida como Aloe vera L., uma espécie originária do Continente Africano, possui diversas propriedades medicinais determinadas por metabólitos encontrados no extrato do parênquima clorofiliano e no parênquima de reserva. Este último, é rico em polissacarídeos, principalmente polimananas do tipo b(1à4). Neste trabalho, foram estudadas as influências de fatores climáticos (temperatura média diária mensal, insolação, precipitação pluviométrica bimestral e umidade relativa diária bimestral) sobre a biossíntese de aloína (antraquinona majoritária) e da fração polissacarídica do extrato do parênquima de reserva ao longo do período de maio/2005 a maio/2006. Para tal, foram utilizadas amostras de população de plantas obtidas via micropropagação, de plantas produzidas no campo e também de folhas coletadas de mesmas plantas e de plantas distintas. A precipitação pluviométrica bimestral foi o fator de maior influência na biossíntese de aloína A, enquanto a fração polissacarídica mostrou-se mais afetada pelos efeitos da insolação e da precipitação pluviométrica bimestral. As análises realizadas na determinação das características físico-químicas e bioquímicas do extrato do parênquima de reserva mostraram teores de glicídios e proteínas proeminentes. Adicionalmente, a FP demonstrou uma pequena variação de conteúdos protéico e glicídico inter-coletas. Entretanto, na FPD o grau de variância foi maior, o que demonstrou a importância da diálise das amostras. A composição monomérica da FPD, utilizando CCD, revelou a presença de manose, glucose e galactose. A utilização das espectroscopias de FT-IR e 13C-RMN permitiu determinar de forma inequívoca a estrutura molecular da acemanana presente nas amostras em estudo, do padrão comercial e da acemanana isolada da fração polissacarídica. A análise quimiométrica (PCAs) viabilizou o estabelecimento de um padrão de distribuição fatorial das amostras de acordo com sua composição química e demonstrou que os efeitos de época de coleta e de diálise das amostras foram significativos para o perfil de agrupamentos observados. Os contaminantes presentes nas amostras e a intensidade de sinais nos espectros de FT-IR foram os principais responsáveis pela dispersão observada das amostras. A 13C-RMN mostrou que a purificação da acemanana não foi suficiente para garantir seu grau de pureza, no entanto, ficou acima do padrão usado comercialmente. Os ensaios de vascularização realizados na vesícula vitelínica e na membrana córioalantóica de Gallus domesticus produziram um efeito anti-vasculogênico e anti-angiogênico, sem comprometer a morfogênese embrionária, nos tratamentos com extrato do parênquima de reserva, da FP e de acemanana, nas concentrações de 10, 30 e 90mg/ovo.

Previous issue date: 2015-05-14Objective: To evaluate the influence of Aloe vera (Aloe barbadensis) in angiogenesis and scar activity Methods: experimental study used 120 fertile eggs of chicken (Gallus domesticus) of Rhoss lineage. The eggs were incubated, and the end of the 13 °, filter paper discs, conveying 3 uL of the solution to be tested (glycolic extract of aloe vera 10%) and the proper controls were deposited directly on the Chorioallantoic Membrane-MCA so carefully to evaluate the angiogenic activity of Aloe vera. The healing activity was evaluated using 15 healthy rats of the species Rattus norvegicus albinus by creating a lesion on the dorsum of each mouse using a rectangular size 2,0x3,0cm mold, after making the injuries were applied the solution to be tested, Aloe vera and the positive and negative controls Results: regarding angiogenic activity observed If through the images that 80% of MCAs which was used Aloe vera was the formation of thicker blood vessels and in greater quantities, but there was no difference significant when compared to the positive control. Regarding scar activity results in macroscopic evaluation showed that 100% of the test group mice showed a complete closure of the lesions on the 21st day of the experiment while only 40% of the control group had complete closure. But when the Tukey test (p> 0.05), there was no statistical difference. Demonstrating how the scar activity of Aloe vera is the same as Regederm® you already have scientific evidence in wound healing. Conclusion: Aloe vera presented healing activity equal to the positive control, the MCA presented angiogenic activity equal to the positive control, with formation of new vessels, it was easy to apply and handling, conclusion themselves with what the Aloe vera extract or pro components -angiogênicos isolates may have potential pharmaceutical applications for wound treatment.
Objetivo: Avaliar a influência do Aloe vera (Aloe barbadensis) na atividade angiogênica e cicatricial Métodos: estudo experimental onde se utilizou 120 ovos férteis de galinha (Gallus domesticus) da linhagem Rhoss. Os ovos foram incubados e ao final do 13°, discos de papel de filtro, veiculando 3 µL da solução a ser testada (extrato glicólico de aloe vera a 10%), e os devidos controles, foram depositadas diretamente sobre a Membrana Corioalantóide-MCA de forma cuidadosa para avaliação da atividade angiogênica do Aloe vera. A atividade cicatricial foi avaliada utilizando 15 ratos saudáveis, da espécie Rattus norvegicus albinus, através da criação de uma lesão no dorsos de cada rato utilizando um molde do tamanho retangular 2,0x3,0cm, após a confecção da lesão eram aplicadas a solução a ser testada, Aloe vera e os controles positivo e negativo Resultados: com relação a atividade angiogênica observou se através das imagens que 80% das MCAs onde se utilizou o Aloe vera houve formação de vasos sanguíneos mais grossos e em maior quantidade, porém não apresentou diferenças significativas quando comparada ao controle positivo. Com relação a atividade cicatricial os resultados na avaliação macroscópica demonstraram que 100% dos ratos do grupo teste apresentaram um fechamento completo das lesões no 21º dia do experimento enquanto que apenas 40% do grupo controle apresentavam fechamento completo. Porém quando aplicado o teste de Tukey, (p>0,05), não houve diferença estatística. Demostrando assim que a atividade cicatricial do Aloe vera é igual à do Regederm® que já possui comprovação cientifica na cicatrização de feridas. Conclusão: o Aloe vera apresentou atividade cicatrização igual ao controle positivo, na MCA apresentou atividade angiogênica igual ao controle positivo, com formação de novos vasos, foi de fácil aplicação e manuseio, Concluindo -se com isso que o extrato de Aloe vera ou componentes pró-angiogênicos isolados podem ter potencial para aplicações farmacêuticas para o tratamento de feridas.

Full textAbstract:
Microcrystalline cellulose (MCC) is the most commonly used excipient in the manufacture of spherical particles or beads by extrusion spheronisation. However, the use of MCC in beads has its limitations such as prolonged release of drugs due to lack of disintegration. The aim of this study was to determine if Aloe vera and Aloe marlothii leaf materials can be used as excipients in the production of beads prepared by extrusion spheronisation. A 23 full factorial design was employed for optimisation and to explore the effects of the concentration of MCC, polyvinylpyrrolidone and aloe materials on the sphericity and release rate of ketoprofen. Scanning electron microscopy revealed more porous beads when aloe materials were included in the bead formulations compared to the formulation with MMC alone. The bead formulations containing aloe materials exhibited faster drug release compared to that of the formulation containing MCC alone. Dissolution data of the optimised formulations were analysed in terms of mean dissolution time (MDT) as well as fit factors (f1 and f2). The optimised bead formulations had dissolution profiles comparable to that of the formulation containing MCC alone at pH 1.2 and 4.5 (f2 values > 70), but less comparable to the reference at pH 6.8 (50 < f2< 65) due to faster drug release. Aloe vera and Aloe marlothii leaf materials can be used successfully together with MCC in the production of beads by extrusion spheronisation.Thesis (MSc (Pharmaceutics))--North-West University, Potchefstroom Campus, 2013.

Full textAbstract:
Harvesting of Aloeferox was estimated (in 1996) to bring in an annual income ofR4 million per year to rural communities alone - a vital source of income for full-time tappers who rely solely on Aloe ferox as their only form of financial survival. They are joined on occasion by casual-tappers who rely on tapping to supplement their incomes in times of hardship (Newton and Vaughan 1996). Landowner's also benefit by allowing harvesting on their land in exchange for a percentage of the harvest (Newton and Vaughan 1996). Trade in bitters sap or gel far outweighs that of other plant parts so care is taken by harvesters to keep the plants alive for future tapping. Leaves from only the lower third of the leaf rosette ( 10 - 15 leaves) are harvested, and 2 - 4 cm at the base of the leaves are left to prevent damage to vascular tissues (Newton and Vaughan 1996, Mac Farlane 2004). Populations are only harvested every 18 - 36 months allowing plants to recover from the loss of leaf material. Plants suffering from insect-infestation or disease are not harvested to avoid weakening the plant further and possibly causing death (Newton and Vaughan 1996). Effort is also made by landowners to relocate plants growing in areas they plan to transform and to monitor harvesting activities on their properties (Newton and Vaughan 1996). The vested interest in keeping the plants alive has inadvertently assured the preservation of populations at past harvesting levels although no formal conservation or resource management policy presently exists for A. ferox (Newton and Vaughan 1996). Effects of harvesting, which are not limited to the direct effect of leaf removal on the plant but include indirect effects - such as reduced reproductive output, reduced sap production and even trampling of recruits - have nonetheless raised concern for the long-term survival of populations (Newton and Vaughan 1996). This study addressed some of the indirect effects of harvesting on Aloe ferox on both population and individual plants levels. On the population level plant density, mortality, susceptibility to disease and sizeclass structure was compared between unharvested and harvested populations. On the individual plant level vegetative traits, flower production and sap production were compared between unharvested and harvested plants. One of few other studies on ecology of A. ferox by Hoffman (1988) assessed some of these characteristics for a population in Port Elizabeth, South Africa.

Abstract
The effect of Aloe vera (L.) Burm. f. (Aloe barbadensis
Miller) gel and whole leaf extract on the permeability
of Caco-2 cell monolayers was determined.
Solutions of gel and the whole leaf extract
were applied to the cell monolayers, and the
transepithelial electrical resistance was monitored
for 2 hours, which was then continued for
another 2 hours after removal of the test solutions
to measure reversibility of the effect. The transport
of insulin in the presence and absence of the
A. vera gel and whole leaf extract solutionswas also
investigated. Both the A. vera gel and whole leaf
extract were able to significantly reduce the
transepithelial electrical resistance of the Caco-2
cell monolayers at concentrations above 0.5% w/
v and thereby showed the ability to open tight
junctions between adjacent cells. This effect was
fully reversible, as the electrical resistance of the
cell monolayers returned to the original value
upon removal of the test solutions. The A. vera
gel and whole leaf extract solutions significantly
enhanced the transport of insulin across the Caco-
2 cell monolayers compared with the control.
The results suggest that these plant products have
a high potential to be used as absorption enhancers
in novel dosage forms for drugs with poor
bioavailabilities when administered orally. On the
other hand, an uncontrolled increase in the bioavailability
of drugs that are taken simultaneously
with A. vera gel and whole leaf extract products
may result in adverse effects, and the potential
exists that toxic blood plasma levels may be
reached.

Full textAbstract:
Thesis (M. Tech. (Biomedical Technology)) -- Central University of Technology, 2014The rising costs of health care, the outbreak of drug resistant organisms, health depleting lifestyles and the risky side effects of currently used drugs are world-wide problems. This has led to the search for novel drugs and drug leads. Traditional healers and other individuals across the globe possess unlimited knowledge on the healing powers of different plants that has been passed on through generations. This knowledge together with scientific investigations can lead to the eradication of most of the diseases either by treatment or prevention. Aloe ferox Mill. is one of the plants that have gained a lot of interest from the pharmaceutical industry. The plant has over 80 documented medicinal uses. These include treatment of impotence and infertility, sexually transmitted infections, arthritis, hypertension, leukaemia, bacterial and fungal infections. It is also known as a blood purifier, widely used as a laxative and anti- inflammatory agent. More research is required to discover more about A. ferox and its benefits to health as well as to investigate its potential for the development of novel drugs. The current study was focused at investigating the anti- cancer, anti- microbial antidiabetic, cytotoxic activities and phytochemical composition of leaf extracts of A. ferox. Three cancer cell lines namely: breast (MCF7), colon (HCT116) and prostate (PC3) cancer cell lines were used to investigate the anticancer activity of the extracts using the Sulforhodamine B (SRB) method. To determine the anti- diabetic activity of the plant extracts the C2C12 and Chang cell in- vitro models of glucose uptake were used. The micro- dilution technique was IV used to evaluate the antibacterial and antifungal activity of the extract. The safety of these extracts against normal human foetal lung fibroblasts (W138), Chang and C2C12 cells was done by through the SRB and the MTT methods. To determine the phytochemical profile of A. ferox the DPPH radical scavenging and the Folin Ciocalteu methods were used to test the antioxidant activity and the total phenolic content of the different extracts respectively. Different methods were used to determine the presence of phytochemicals such as steroids, saponins, alkaloids, carbohydrates and flavonoids. LCMS was also done to detect the elemental composition of the plant extracts. According to the CSIR criteria A. ferox was inactive against the cancer cell lines used. It however exhibited antioxidant activity even at low concentrations, with an EC50 of 0.865 ± 0.783. The methanol extract showed more phenolic content than the dichloromethane and aqueous extracts at a concentration of 5mg/ml. It is believed that the antioxidant activity correlates with the phenolic content and quality of the phenols present in the plant and more assays have to be done to prove this hypothesis. Other phytochemicals found in the extract included saponins, steroids, alkaloids as well as flavonoids. Both the methanol and aqueous extracts of A. ferox caused a significant increase in glucose uptake by C2C12 cells but caused a slightly decreased uptake by the Chang cells. The plant extracts inhibited the growth of Staphylococcus epidermidis, Streptococcus pneumonia, Escherichia coli and Candida albicans at a concentration of 15mg/ml extract. Candida tropicalis and Escherichia faecalis were resistant to A. ferox extracts. Finally the extracts showed no toxic activity against the normal foetal lung fibroblasts, Chang and C2C12 cells validating the safety of this plant for human use. V The results in conjunction with literature findings show A. ferox to be a promising source of drugs and therapeutic agents. Due to the fact that traditional healers already rely on it as treatment for different ailments, it is important that the safety of the plant for use has been validated though other studies and clinical trial still need to be done to fully confirm this. All the information gathered also showed this plant to be of great benefit against major health problems, responsible for millions of deaths each year such as cancer, cardiovascular and inflammatory diseases, and diabetes. There is however still a great need for more investigation to be done on this plant against a vast majority of organisms and diseases so as to fully benefit from it.

Magister Scientiae - MSc (Chemistry)Global climate change and geographical differences are two major parameters known to have, either, direct or indirect influence on the production of secondary metabolites in plants, which in-turn may affect the quality and/or quantity of the overall metabolites. The primary purpose of this thesis was to evaluate the phytochemistry of the whole leaf of Aloe succotrina Lam. spp. - a South African native plant - through a chromatographic spectroscopic approach-against available data accumulated for the cultivated population. Preliminary screening of the crude extracts i.e. HEX, DCM and EtOAc on TLC aluminium plates precoated with silica gel 60 F254 followed by various chromatographic separation, led to the isolation of five known compounds: ?-sitosterol (1) and two anthrone-C-glycosides (2 and 5), including two coumarin derivatives-the aglycone (3) and glycoside derivative (4). Notably, apart from 5 and 2, the accumulation of 1, 3 and 4 in A. succotrina Lam. spp. is reported for the first time. Structural elucidation of the individual compounds was achieved by extensive spectroscopic analysis i.e. MS, IR, 1H and 13C-NMR spectroscopy and in some cases comparison to the literature. A comparative HPLC chromatogram of the crude MeOH extract of the leaves of A. succotrina Lam. was developed for qualitative (and quantitative) identification of the active metabolites, which could be realized by VWD with detection at 290 nm.

Full textAbstract:
Atopic dermatitis (AD) typically develops in patients with a history of allergic ailments, and is characterised by an itchy, inflammatory skin condition with scaling, lichenification, papules, excoriations and pruritus. In AD patients a chronic relapsing inflammatory condition is seen, associated with IgE hyper production. AD flares are largely triggered by environmental factors. However, the exact etiology of AD is unclear and there is a pressing need for new treatment regimens as AD is a chronic condition and requires long term treatment. Historically Aloe has been used to treat skin conditions as well as a variety of other diseases. To further explore the pathogenesis and treatment of AD, Balb/c mice were sensitized and challenged with 2,4-dinitrochlorobenzene (DNCB) for atopic dermatitis induction. Thereafter, mice were treated with either Aloe ferox or Aloe vera applied daily on the dorsal skin for 10 consecutive days. A placebo gel was used for the control mice. Blood was collected at the end of the treatment period and serum IgE levels measured. Serum IgE levels were significantly lowered in the Aloe ferox group than in the Aloe vera group. This study demonstrated Aloe’s immunoregulatory potential for alleviating atopic dermatitis through influencing of Th2 cell activation.Dissertation (MSc)--University of Pretoria, 2013.

Many of the health benefits associated with Aloe vera have been attributed to
the polysaccharides contained in the gel of the leaves. These biological activities include promotion of wound healing, antifungal activity, hypoglycemic or antidiabetic effects antiinflammatory,
anticancer, immunomodulatory and gastroprotective properties. While the
known biological activities of A. vera will be briefly discussed, it is the aim of this review to further highlight recently discovered effects and applications of the leaf gel. These effects include the potential of whole leaf or inner fillet gel liquid preparations of A. vera
to enhance the intestinal absorption and bioavailability of co-administered compounds as well as enhancement of skin permeation. In addition, important pharmaceutical applications such as the use of the dried A. vera gel powder as an excipient in sustained release pharmaceutical dosage forms will be outlined.

The Black South African literary oeuvre has as its dominant background township life. There has been a considerable neglect of village or rural setting. Even the proliferation of writing that has been regarded as depicting genuine African experience has fallen short of remedying this malady. There is a paucity of writings that endeavour to depict rural communities, and even where South African writers attempted to depict rural community, theirs has been an indolent attempt, as evinced by a lack of insight in such writings. One example is Matshoba's Call Me Not A Man. which is merely a glimpse into the rural setting. This shortcoming, coupled with a travesty of the rural setting, suggests a non-existence of the rural community. Whether South African writers, especially, Black writers, eschew rural setting deliberately or not is open to debate. Hence my project has as its paramount aim an endeavour to expose authentic rural realities. This collection, therefore, portrays rural life against the backdrop of city life. This paradoxical juxtapositioning is a deliberate attempt to enable the reader to extricate real-life happenings from both scenarios, and have a sound judgement about his/her observation.

Cacti, agaves and yuccas are classified as succulents, plants that have highly specialized anatomical features such as thick waxy cuticles, fleshy or minimal leaves, modified leaves (spines), and roots with extra storage capabilities for food and water. These modifications allow them to survive and thrive in harsh desert environments. They survive long periods of drought in areas of sparse rainfall and intense heat. During stressful periods, many succulents cease to grow, drop unnecessary leaves, dehydrate and become dormant until conditions for growth return. Despite their adaptations, succulents suffer from diseases, insect pests and cultural problems. Some of the more common problems that occur in cacti, agave and yuccas in Arizona are discussed in this bulletin.

Full textAbstract:
In this study I documented the convergence of five congeneric bird-pollinated plants (Aloe pluridens, A. lineata var. muirii, A. speciosa, A. africana, and A. ferox) into three functional groups based on size, shape, and the arrangements of flowers on the inflorescence, but also nectar rewards, pollen deposition sites on the bird-pollinators, and the degree to which bees play a role in their pollination. Individuals of similar functional groups were divergent in their peak flowering times and limited their degree of flowering overlap further by spatial aggregation and niche separation, within the Thicket of the Gamtoos River Valley. The nectar properties were especially useful in structuring the bird pollinator community, which resulted in greater ethological isolation and hence, greater reproductive assurance in the mixed co-flowering plant communities. Choice array experiments revealed that it was the fine scale aggregation of flowering individuals that ensured that bird-pollinators feed selectively, since when equal choice was available, interspecific visitation increased significantly compared to natural scenarios. Bird behaviour and the ecological intermediateness of one to the species explained its prominence in hybrid combinations. The spatial occurrence of hybrid individuals can be traced back to the energetics of foraging and its influence on bird floral constancy. The pollination ecology of similar South African Aloe species were extrapolated from these and recent findings by various authors, but emphasises the need for a robust natural phylogeny of the Aloaceae in order to draw comprehensive conclusions on the evolutionary radiation of this highly charismatic group.

Oral mucositis (OM) is a frequent dose-limiting and costly complication of antineoplastic chemotherapy. It’s caractherized by ulcerative lesions and causes pain, restrict food and fluids oral intake and causes substancial risk for sepsis. In severe cases, hospitalization, parenteral nutrition and opiode analgesics are required. OBJECTIVES: Evaluate the effects of extracts of two herbal medicines, Aloe barbadensis Miller (Ab) and Myracrodruon urundeuva Allemão (Mu) on 5-fluorouracil-induced OM in hamsters. To evaluate the possible mechanisms by the extracts act, it was performed analysis of intensity of activity of myeloperoxidase (MPO) and analysis of immunohistochemistry for TNF-alpha and iNOS in mucosa specimens. METHODS: Golden siriam hamsters were submitted to intra-peritoneal 60 and 40 mg/Kg injections of 5-fluorouracil (5-FU) in day 1 and 2, respectively. On day 4, animals were submitted to anaesthesia, followed by mecanic trauma with needle to potenciate the effect of 5-FU. After that, the mucosas were treated with topical gel containing Mu extracts at 5, 10 or 20%, Ab extracts at 25, 50 or 100% (experimental groups) or carbapol gel (control group). The treatments above were mantained twice daily until day 9. On day 10 the animals were sacrified. Diferent parameters were evaluated: macroscopic and microscopic scores of OM, body mass variation and immunohistochemistry for TNF-alpha e iNOS. RESULTS: Mu significantly inhibited macroscopic oral mucositis at 5 and 10% concentrations (5% Mu – Md 2; 10% Mu – Md 3; control – Md 4, p < 0,01). Ab also inhibited OM (25% Ab – Md 1; 50% Ab – Md 1,5; 100% Ab – Md 1; control – Md 4, p < 0,001). These results were confirmed by histological analysis (5% Mu – Md 1,5; 10% Mu – Md 1; 25% Ab – Md 1; 50% Ab – Md 1,5; 100% Ab – Md 1; control – Md 2, p < 0,01). MPO activity was significantly decreased by Mu and Ab compared to control animals. Both Mu and Ab decreased expression of TNF-alpha and iNOS on tissue. It was observed a decrease on ponderal lost in experimental groups. CONCLUSIONS: Myracrodruon urundeuva and Aloe barbadensis cause important inhibitory effects in oral mucositis 5-FU induced probably by their antiinflamatory properties.
A mucosite oral (MO) é um efeito colateral frequente em pacientes sob tratamento oncológico, em especial à quimioterapia (QT). Caracteriza-se por hiperemia, edema e úlceras em toda a cavidade oral e faringe. A importância da MO é devido à dor, alterações do paladar e infecções locais. Surge incapacidade de alimentar-se, ingerir líquidos, risco de infecções sistêmicas, necessidade de interrupção da QT, necessidade de hospitalização, tornando o tratamento mórbido, dispendioso, doloroso e muitas vezes impossível ou ineficaz. Ainda não há terapêutica totalmente eficaz, com nível de evidência que torne a MO manejável. OBJETIVOS: Avaliar os efeitos do tratamento tópico com duas plantas medicinais, a Myracrodruon urundeuva (aroeira) e a Aloe barbadensis (babosa) sobre o desfecho da MO experimental induzida por 5-Fluorouracil (5-FU) em hamsters, através de escores macro e microscópicos e avaliação de perda ponderal. Investigar os possíveis mecanismos envolvidos nesses efeitos, através de análise da atividade de mieloperoxidase (MPO) e expressão tissular de TNF-alfa e iNOS. MATERIAIS E MÉTODOS: Hamsters Goldem siriam receberam injeções i. p. de 60 e 40 mg/Kg de 5-FU, nos dias 1 e 2, respectivamente. No dia 4 os animais eram anestesiados, tinham suas mucosas jugais submetidas a trauma mecânico (TM) com agulha de ponta romba. Em seguida, eram tratadas com gel inerte (controle), gel de aroeira a 5, 10 ou 20% (AR) ou gel de babosa (ALOE) a 25, 50 e 100% . Tais tratamentos eram realizados 2xdia até o dia 9. Os animais eram pesados diariamente. No dia 10, ocorriam os sacrifícios para: 1. Análise macroscópica das mucosas; 2. Retiradas de amostras para histopatologia, imunohistoquímica para e dosagem de MPO. RESULTADOS: Na análise macroscópica, AR determinou inibição significativa da MO (AR 5% - Md 2; AR 10% - Md 3; Controle – Md 4), ALOE também inibiu a MO (ALOE 25% - Md 1; ALOE 50% - Md 1,5; ALOE 100% - Md 1; Controle – Md 4). À histopatologia confirmou-se inibição significativa da MO pela AR (p < 0,01) e pela ALOE a 50 e 100% ( p< 0,01). Houve também inibição dos níveis de MPO pelos extratos das duas drogas e a expressão de TNF-alfa e iNOS também foi reduzida. Houve uma tendência a uma menor perda ponderal nos grupos experimentais. CONCLUSÕES: Extratos de ALOE e AR foram capazes de inibir a MO experimental induzida por 5-FU através de aplicações tópicas e tal efeito pode ser modulado por suas atividades anti-inflamatórias sobre a produção de citocinas envolvidas com o processo e de NO.

El objetivo de este estudio fue evaluar el efecto de la disponibilidad de agua en la producción de biomasa aérea y en la eficiencia en el uso del agua (EUA) de Aloe vera (Aloe barbadensis Miller). El trabajo se realizó en condiciones de invernadero en el Campus Antumapu de la Facultad de Ciencias Agronómicas de la Universidad de Chile y comprendió la temporada 2007 y 2008. Los tratamientos hídricos se evaluaron a través de variación del peso de las macetas. El tratamiento 1 (T1) consistió en mantener las macetas entre el 60% y el 80% de la capacidad de campo (C. de C.) del suelo y el T2 consistió en mantener entre el 30% y el 50% de la C. de C. del sustrato. Para evaluar crecimiento se realizaron cosechas cada 45 días, con la finalidad de obtener: materia verde, materia seca, área foliar, número de hojas, número de hijuelos, distribución de asimilados y eficiencia del uso del agua. Las variables: EUA y distribución de asimilados, presentaron diferencias que estadísticamente no fueron atribuibles al efecto del tratamiento. Las variables: materia seca, materia verde, número de hojas, número de hijuelos y área foliar, presentaron diferencias que estadísticamente fueron atribuibles al efecto del tratamiento. El valor promedio calculado de EUA para la especie, en función de la materia seca fue de 10,8 g de MS L-1 kPa-1 para el T1 y T2. Mientras que los valores promedio calculado de EUA en función de la materia verde fueron de 85 y 68 g de MV L-1 kPa-1 para el T1 y T2 respectivamente. La distribución de asimilados en la planta para el T2 favoreció el desarrollo de las raíces, las que se encontraron más dispersas y en mayor cantidad alcanzando un 43% del peso total de la planta, todo esto como estrategia de sobrevivencia ante una condición hídrica desfavorable.
Aloe vera is a CAM species resistant to drought of great economic development because it has important properties related to the area of cosmetics, food and drug, is an appropriate species to be cultivated in arid and semiarid areas. The objective of this study was to evaluate the effect of water availability in biomass production and efficiency in water use (WUE) of Aloe vera (Aloe barbadensis Miller). The work was conducted under greenhouse conditions Antumapu Campus of the Faculty of Agricultural Sciences, University of Chile and understood the 2007 season and 2008. Water treatments were assessed through measurements on the variation of the weights of the pots. Treatment 1 (T1) was to keep the pots between 60% and 80% of field capacity (C. of C.) soil and T2 was to keep between 30% and 50% of the C. of C. the substrate. To evaluate growth harvests were performed every 45 days, in order to obtain: dry matter, leaf number, number of tillers, green matter, leaf area, water use efficiency and distribution of assimilates. The variables: WUE and distribution of assimilates, presented statistical differences were not attributable to treatment effect. The variables: dry matter, fresh matter, leaf number, number of tillers and leaf area, showed statistically differences were attributable to treatment effect. The calculated value of WUE for the species, based on the dry matter was 10.8 g DM L1 kPa-1 , for the T1. While the average values calculated according to the GM borders was between 85 and 68 g GM L-1 kPa-1 for de T1 and T2 respectively. The distribution of assimilates in the plant for T2 favored the development of roots, which were more dispersed and more of reaching 43% of the total weight of the plant, all of this as a survival strategy to unfavorable water conditions.

Previous issue date: 2010Aloe ferox, Asphodelaceae, é uma planta que se desenvolve em terras com chuvas mais ou menos moderadas e secas e solos menos férteis; possui ampla distribuição em toda a África do Sul, tendo maior concentração nas Províncias do Cabo Leste e Oeste. No Brasil, esta planta é encontrada no interior de São Paulo, Santa Catarina e na região nordeste; sendo esta última a que possui melhores condições de cultivo. Aloe ferox é popularmente utilizada como laxante, porém existe uma carência de estudos referentes à eficácia de seu uso como laxante bem como de informações toxicológicas detalhadas sobre a espécie. Neste contexto, o trabalho teve como objetivo avaliar o efeito da resina de Aloe ferox Miller sobre o trânsito intestinal em ratos e investigar a segurança de seu uso. Para isso foram realizados o teste de motilidade intestinal em camundongos, nas doses de 0.05, 0.1 e 0.2 g/kg, teste de toxicidade aguda em ratos e avaliou-se a influência da administração crônica (13 semanas) por via oral do extrato da resina de Aloe ferox, nas doses de 0.1, 0.5 e 1.5 g/kg, sobre os parâmetros bioquímicos, hematológicos e morfológicos em ratos. Os resultados mostraram que na toxicidade aguda, Aloe ferox não produziu morte dos animais em doses de até 5 g/kg. Para a atividade laxante, observou-se que após 30 minutos da administração Aloe ferox aumentou a motilidade intestinal em camundongos em mais de 90% em todas as doses administradas. No entanto, a administração crônica promoveu alterações em vários parâmetros bioquímicos, hematológicos e morfológicos. No que se diz respeito aos parâmetros hematológicos, Aloe ferox, na dose de 1.5 g/kg induziu uma redução nos valores de eritrócitos, hematócrito e hemoglobina nos primeiros trinta dias de tratamento e aumento dos valores desses parâmetros no último mês de tratamento para ambos os sexos e promoveu o aumento do RDW em fêmeas tratadas com a mesma dose (1.5 g/kg). Com relação aos parâmetros bioquímicos, os animais tratados com Aloe ferox na dose de 1.5 g/kg sofreram uma redução nos níveis de creatinina e aumento de bilirrubina total e indireta em ambos os sexos. Nas fêmeas verificou-se uma redução nos níveis de HDL e triglicerídeos e aumento de bilirrubina direta. Os machos apresentaram aumento de fosfatase alcalina e ALT. A análise morfológica de vísceras, encéfalo e órgãos reprodutivos bem como a massa absoluta e relativa destes órgãos apresentou alterações nos animais que sobreviveram ao tratamento com Aloe ferox na dose de 1.5 g/kg. As principais alterações observadas foram massa absoluta e relativa diminuída do baço em fêmeas e do intestino nos machos. Os resultados encontrados nos levam a concluir que Aloe ferox é eficaz no tratamento da constipação intestinal, porém induz alterações significativas em vários parâmetros bioquímicos, hematológicos e morfológicos em ratos Wistar de ambos os sexos, indicando que a administração desta planta pode exercer efeito tóxico ao ser humano

A Aloe vera, popularmente denominada babosa no Brasil, é uma planta originária da África, utilizada por culturas antigas do Mediterrâneo e do Egito devido às suas propriedades terapêuticas e medicinais. O extrato do parênquima de reserva desta planta, denominado gel de A. vera, apresenta ampla gama de compostos que possuem atividades farmacológicas de interesse medicinal. A incorporação de porções de A. vera no desenvolvimento de novos materiais, como a celulose bacteriana (CB), promove alterações morfológicas, mecânicas e químicas de grande interesse para engenharia tecidual e na produção de novas classes de dispositivos biomédicos. Na produção dos hidrogéis celulose bacteriana e A. vera, o meio de cultura da bactéria Gluconacetobacter hansenii foi formulado com três porções de A. vera, variando as concentrações de 20%, 40%, 60%, 80% a 100% (v/v). Apenas as formulações de 20%, 40% e 60% (v/v), das três porções, produziram com sucesso materiais com características distintas e singulares de microestrutura, caracterizadas por microscopia eletrônica de varredura (MEV); de propriedades mecânicas, químicas, avaliadas qualitativamente por espectroscopia de infravermelho por refletância total atenuada (FTIR-ATR); e também foram caracterizadas quanto à capacidade de absorção de água e cristalinidade. Além disso, células de fibroblastos da linhagem L929, foram semeadas sobre os materiais para avaliação da citotoxicidade, adesão e morfologia celular em função do tempo. Os fibroblastos permaneceram viáveis em até 48 horas de cultura em todos os hidrogéis desenvolvidos e apresentaram morfologia alongada e melhor aderência nas membranas formuladas com 60% das três porções. Os materiais formulados com 60% de A. vera na celulose bacteriana se mostraram plataformas promissoras para o desenvolvimento de dispositivos para regeneração de pele.
Abstract : Aloe vera, usually known in Brazil as "babosa", originary plant from Africa, was used by ancient cultures of the Mediterranean and Egypt due to therapeutic and medicinal properties. The parenchyma reserve extract of this plant, called A. vera gel, presents a wide range of compounds which has pharmacological activities of medicinal interests. The incorporation of A. vera portions in development of new materials, such as bacterial cellulose (BC), promotes morphological, chemical and mechanical changes of great interests for tissue engineering and production of new classes of biomedical devices. In the production of bacteria cellulose and A. vera hydrogels, the culture medium of the bacteria Gluconacetobacter hansenii was formulated with three portions A. vera, raging the concentrations from 20%, 40 %, 60 %, 80% to 100% (v/v). Only formulations of 20 % , 40 % and 60 % (v/v), for three portions, produced successfully materials with distinct and unique characteristics of microstructure; characterized by scanning electron microscopy (SEM); mechanical and chemical properties; evaluated qualitatively by infrared spectroscopy by attenuated total reflectance (FTIR-ATR), and were also characterized by their ability to absorb water and crystallinity. Moreover, fibroblast cells of the L929 strain were seeded on the material to evaluate cytotoxicity, cell adhesion and morphology as a function of time. Fibroblasts remained viable for up to 48 hours of culture, in all developed hydrogels, and showed elongated morphology and better adhesion on the membranes formulated with 60 % of the three portions. The materials formulated with 60% of A. vera into bacterial cellulose proved are promising scaffold for the development of new devices for skin regeneration.

Full textAbstract:
The most important indigenous bee plant in South Africa is the winter flowering Aloe greatheadii var davyana, with a widespread distribution across the summer rainfall region. Beekeepers commonly move their hives to the "aloe fields" during winter, using the strong pollen and nectar flow for colony growth, queen rearing and honey production. In spite of its importance for the bee industry, no complete pollen analysis is available and, except for the popular bee literature, little is known about nectar production or pollinators. The aim of the study was therefore to evaluate the floral rewards of this aloe and to investigate the importance of these resources for honeybees. We analysed fresh, bee-collected and stored aloe pollen for its nutritional content (not previously done for any plant species). Addition of nectar and glandular secretions leads to an increase in water and carbohydrate content and a decrease in protein and lipid content. All the essential amino acids, except tryptophan, met or exceeded the minimum levels for honeybee development. In worker bees in queenright colonies, ovarian development is greater on aloe than on sunflower pollen, which may be explained by the exceptionally high protein content and high extraction efficiency during digestion. In assessing the nectar resource, we investigated the nectary structure and nectar presentation of two species belonging to different sections of the genus Aloe, A. castanea and A. greatheadii var davyana, but anatomical differences were not related to the nectar production. We looked at variation in nectar volume and concentration of A. greatheadii var davyana on various levels, from within the flowers to across the summer rainfall area. Nectar was continuously available and, although dilute (mean concentration 18.6%), the nectar of A. greatheadii var davyana is more concentrated than that of other Aloe species, making it an ideal source of energy and water for honeybees. Utilisation of dilute nectar by bees requires elimination of much excess water. We sampled crop contents of nectar foragers to determine if changes in nectar concentration occurred after collection and before unloading in the hive. Contrary to the common assumption that nectar is either unchanged or slightly diluted during transport, we observed a dramatic increase in concentration and a decrease in volume between the flowers and the hive. Bees may be foraging primarily to get enough water for their physiological needs. Using miniaturised data loggers, we showed that bees are able to adjust nest humidity within sub-optimal limits, in addition to efficient regulation of hive temperature. Humidity levels are influenced by trade-offs with regulation of temperature and respiratory gas exchanges. Although the dilute nectar and pinkish red tubular flowers are characteristic of bird-pollination, exclusion experiments showed that bees are the primary pollinators of A. greatheadii var davyana. This contrasts with other Aloe species which are pollinated by sunbirds and other passerine birds, but highlights the two-way interaction between the bees and the aloes.Thesis (PhD (Entomology))--University of Pretoria, 2008.

Estudos têm revelado que a planta Aloe vera possui muitas substâncias com propriedades farmacêuticas tais como ação cicatrizante, imuno-estimulante, fungicida entre outras. O uso de seu extrato pode ser eficiente no tratamento de problemas advindos do manejo na piscicultura, como no transporte, onde ocorrem injúrias e quadro de estresse com imunossupressão. O presente trabalho avaliou os efeitos da Aloe vera adicionada na água no transporte de juvenis de matrinxã (Brycon amazonicus) em indicadores hematológicos, metabólico e imunológico. Após 48 horas de jejum, peixes foram transportados em diferentes concentrações de Aloe vera (0%; 0,002%; 0,02% e 0,2%) e amostrados antes do transporte (nível inicial – n=8), às 2 horas de transporte (n=10), após 4 horas (na chegada – n=8), 24 e 96 horas depois do transporte (período de recuperação – n=8). Após o transporte, os peixes foram distribuídos, conforme o tratamento, em quatro caixas de 1.000 litros, com fluxo contínuo de água. No sangue total foram determinados o hematócrito, número e volume de eritrócitos, concentração de hemoglobina e atividade respiratória de leucócitos, e no plasma a concentração de glicose. Os resultados hematológicos não apresentaram padrão consistente. A glicemia aumentou após duas e quatro horas de transporte nos peixes de todos os tratamentos, sem diferença entre eles, e voltou aos valores iniciais (pré-transporte) 24 e 96 horas pós transporte. Na atividade respiratória dos macrófagos houve um aumento em duas horas de transporte nos peixes expostos à Aloe vera. A Aloe vera também aumentou a atividade respiratória dos macrófagos in vitro, provando assim sua ação imunoestimulante. Os resultados indicam que a adição de Aloe vera na água de transporte não afetou as respostas metabólica e hematológicas, mas potenciou a resposta imunológica não específica
Aloe vera has many substances with pharmaceutical properties such as wound healer, immunostimulant, fungicide and others. The use of its extract can be effective in the treatment of problems caused by the handling of fish, such as in the transport, when injuries occur, and the stress can reduce immune responses of fish. This study evaluated the effects of Aloe vera added to the water in the transport of juvenile matrinxã (Brycon amazonicus) in hematological, metabolic and immune indicators. After 48 hours of fasting, fish were transported in different concentrations of Aloe vera (0%, 0.002%, 0.02% and 0.2%) and sampled before transport (initial - n = 8) at 2 hours of transport (n = 10), and 4 hours (arrival - n = 8), 24 and 96 hours after the procedure (recovery - n = 8). At arrival, fish were distributed, according to the treatment, in four tanks of 1.000 l, with a continuous water flow. Fish blood was drawn and hematocrit, number and volume of erythrocytes, hemoglobin, respiratory activity of leukocytes, and glucose concentration were determined. The results did not show any consistent pattern in hematological indicators. Plasma glucose concentration increased after 2 and 4 hours of transport in fish of all treatments, without difference among them, and returned to basal amount in 24 and 96 hours after transport. The respiratory activity of macrophages increased within 2 hours of transport in fish exposed to Aloe vera. Aloe vera also increased the respiratory activity of macrophages in vitro, reinforcing its stimulanting effect. The results indicate that the addition of Aloe vera in water transport did not affect the metabolic and hematological indicators, but enhanced the nonspecific immune response tested

Full textAbstract:
El uso de películas comestibles sobre productos alimenticios no es un tratamiento innovador ya que se realiza desde hace años con el objeto de aumentar el tiempo de almacenamiento y mejorar el aspecto de numerosos alimentos (Parzanese, M.; 2012). Muchos autores han recurrido a la utilización de gel de aloe sp como recubrimiento de frutas y hortalizas como una mejor alternativa a los productos sintéticos, ya que el aloe cuenta con numerosas propiedades terapéuticas y beneficios conocidos desde la antigüedad, tales como: cicatrizante, conservante, antioxidante, entre otros, además de aportar una amplia variedad de minerales y aminoácidos esenciales necesarios para el ser humano (Martínez-Romero, 2006). Debido a que se utiliza vaselina para dar brillo en ciruelas desecadas con el fin de mejorar la apariencia final del producto, es el objetivo de este trabajo el evaluar el uso de gel aloe sp como recubrimiento en ciruelas desecadas como alternativa no sólo para mejorar la apariencia de las ciruelas desecadas con un producto natural, sino también otorgarle un beneficio extra al contar con las propiedades que posee la planta del aloe sp. Para realizar el experimento se dividió a las ciruelas en tres partes, a dos de ellas se las trató con gel de aloe sp (una parte con gel natural y la otra con gel comercial), la parte restante se reservó como testigo. Se realizaron 10 observaciones en total, para las cuales se tomaron muestras 1 vez por semana el primer mes y luego 1 vez cada 15 días durante 135 días. El análisis fisicoquímico de las ciruelas desecadas consistió en determinar la consistencia a través de un presiómetro, el color utilizando el colorímetro Minolta y la humedad a través del método directo de Dean Stark. Con el propósito de cumplir los objetivos se realizaron 3 evaluaciones sensoriales en distintos momentos del experimento. Dicha evaluación se diagramó de manera de establecer al inicio las características típicas, a los 15 días para ver posibles cambios y luego, al finalizar el ensayo a los 135 días. Para la obtención de la muestra de ciruelas desecadas se realizó un muestreo aleatorio estratificado con afijación simple, sacándose 30 ciruelas por tratamiento (incluido el testigo). En cada evaluación sensorial se contó con una cantidad de 30 consumidores encargados de evaluar el producto en sus distintas características, tales como aspecto general, consistencia, textura, color, olor y sabor, además se les pidió que indicaran su nivel de aceptación y preferencia. La respuesta obtenida en cada variable, de cada tratamiento, fue analizada mediante Test de Tukey, mientras que para los atributos de las evaluaciones sensoriales se emplearon métodos no paramétricos (prueba de Friedman); además se realizó un perfil sensorial. No se observaron diferencias respecto a la consistencia en las ciruelas desecadas tratadas o no a lo largo del experimento. En las ciruelas desecadas tratadas con gel de Aloe sp natural se observó, al final, una menor luminosidad y tonalidades más rojas oscuras violáceas; además de un aspecto general menos agradable durante la evaluación sensorial pero presentaron un olor característico. En las ciruelas desecadas tratadas con gel de aloe sp comercial, se observó una mayor humedad (sin superar lo reglamentado), un aspecto general más agradable, un color y sabor más característico y una textura más blanda hacia el final del experimento; además de, una mayor luminosidad, mayores tonos rojos y menores tonos azules. Al final del ensayo, la aceptación de los consumidores fue del 90% entre “me gusta mucho y me gusta", para los tratamientos con aloe. En cuanto a la preferencia se distinguió el tratamiento con aloe comercial con un 43%.Fil: Lara Di Giorgio, Lucía. Universidad Nacional de Cuyo. Facultad de Ciencias Agrarias.

The aim was to evaluate the effect of the Aloe vera gel (Aloe barbadensis Miller), in association with the Tris base (hydroxymethyl aminomethane) or powdered coconut water (ACP- 106®) in canine semen conservation, as well as the action of this gel in the renewal process of the extender. Semen samples from five dogs, of breed Basset Hound, were used. In Experiment 1, samples were diluted in duplicate, using Tris plus 20% egg yolk (G1 and G2) or 5% Aloe vera (G3 and G4) and evaluated at 0, 48, 72 and 96 hours. After 48 hours, all samples were centrifuged for 10 minutes (400g) in a cooled centrifuge (5 °C). In the groups G1 and G3 the supernatant was removed and a new extender was added. In the other groups (G2 and G4) pellets were re-diluted in the same supernatant, without renewal. For Experiment 2, samples were divided into two equal aliquots, according to the treatments (G1: Tris + 20% egg yolk, control G2: Tris + 5% Aloe vera; G3: ACP-106® + 5% Aloe vera) and evaluated at 0, 24, 48 and 72 hours after cooling. In both experiments were performed sperm kinetics and membrane integrity analysis (iMP). In Experiment 1 results the diluent renewal did not affect on any parameter analyzed in the group using egg yolk (G1), shown when comparing the two treatments of this substance. The G2 (without renewal) did not demonstrate a significant difference when compared to G1 (renewal). However, groups with Tris-Aloe vera (G3 and G4) were lower (P <0.05) than the groups with Tris-egg yolk (G1 and G2) after the renewal, and this has showed deleterious effect on the group that sperm received new diluent (G3) in all parameters. There were no statistical differences in Experiment 2 in the parameters of total motility, straightness and oscillation index and plasma membrane integrity comparing treatments and evaluation times. However, the progressive motility in G1 proved to be significantly higher (P <0.05) than the other treatments in the first assessment period (0h). However, at 24 the G3 showed values similar to G1. The linearity values of G3 were significantly higher (P <0.05) than other groups from the start of the evaluations. According to the findings from Experiment 1, it can be concluded that the replacement of diluent is not necessary for the preservation of canine spermatozoa undergo cooling (5 °C) for 96 h. Furthermore, it was found that the gel of Aloe vera may be used to replace egg yolk in dog semen cooling diluent at a concentration of 5% without renewal. In the Experiment 2, it can be concluded that Aloe vera can be used at a concentration of 5% to replace egg yolk in dog semen cooling diluent, regardless of the one used.
Objetivou-se avaliar o efeito do gel da planta Aloe vera (Aloe barbadensis Miller), associado ao diluidor Tris (hidroximetil aminometano) ou Água de coco em pó (ACP-106®) na conservação de sêmen de cães, bem como a ação desse gel no processo de renovação do diluidor. Foram utilizadas amostras seminais de cinco cães da raça Basset Hound. No Experimento 1, as amostras foram diluídas em duplicata, utilizando Tris + 20% de gema de ovo (G1 e G2) ou 5% de Aloe vera (G3 e G4), e avaliadas nos tempos de 0, 48, 72 e 96 horas. Após a análise de 48h, todas as amostras foram centrifugadas por 10 min (400g) em centrífuga refrigerada (5 ºC). Nos grupos G1 e G3 o sobrenadante foi removido e um novo diluidor foi adicionado. Nos outros grupos (G2 e G4) os pellets foram re-diluídos no mesmo sobrenadante, sem renovação. Para o Experimento 2, as amostras foram divididas em alíquotas iguais, de acordo com os tratamentos (G1: Tris + 20% gema de ovo, controle; G2: Tris + 5% Aloe vera; G3: ACP-106® + 5% Aloe vera) e avaliados nos tempos de 0, 24, 48 e 72 horas após refrigeração. Em ambos experimentos foram realizadas análises de cinética espermática e de integridade da membrana (iMP). Nos resultados do Experimento 1 a renovação do diluidor não influenciou em nenhum parâmetro analisado no grupo que utilizou gema de ovo (G1), fato evidenciado quando comparados os dois tratamentos que utilizaram esta substância. O G2 (sem renovação) não determinou diferença significativa quando comparado ao G1 (com renovação). Entretanto, os grupos com Tris-Aloe vera (G3 e G4) foram inferiores (P<0,05) aos grupos com Tris-gema de ovo (G1 e G2) após a renovação, e esta mostrou efeito deletério nos espermatozoides do grupo que recebeu novo diluidor (G3), em todos os parâmetros. No Experimento 2 não foram encontradas diferenças estatísticas nos parâmetros de motilidade total, retilinearidade e índice de oscilação e integridade de membrana plasmática quando comparados os tratamentos e os tempos de avaliação. Entretanto, a motilidade progressiva no G1 mostrou-se significativamente superior (P<0,05) aos demais tratamentos no primeiro tempo de avaliação (0h). No entanto, às 24h o G3 demonstrou valores semelhantes ao G1. Os valores de linearidade no G3 foram significativamente superiores (P<0,05) aos demais grupos desde o início das avaliações. De acordo com os achados do Experimento 1, pode-se concluir que a renovação do diluidor não é necessária para a preservação dos espermatozoides caninos submetidos à refrigeração (5 ºC) por 96 h. Além disso, constatou-se que o gel da Aloe vera pode ser utilizado em substituição à gema de ovo, no diluidor de refrigeração de sêmen de cães, na concentração de 5%, sem renovação do diluidor. Já no Experimento 2, pode-se concluir que a Aloe vera pode ser empregada na concentração de 5% em substituição à gema de ovo no diluidor de refrigeração de sêmen de cães, independente do diluidor utilizado.

Full textAbstract:
Mestrado em BiotecnologiaA partir do momento em que um fruto é colhido da planta mãe, têm lugar uma série de alterações ao nível estrutural, químico, nutricional, bioquímico e enzimático, que conduzem, em última análise, ao período de senescência, no qual o fruto deixa de ser comestível. No sentido de permitir a manutenção dos frutos num estado comestível durante um espaço de tempo mais alargado, foram desenvolvidos e postos em prática, nas últimas décadas, métodos e tecnologias que permitem minorar a degradação das características fisiológicas dos mesmos. A aplicação de revestimentos comestíveis em frutos é um desses métodos. A implementação desta técnica cria uma barreira protectora semipermeável na superfície do fruto, tendo um efeito inibitório de determinadas alterações características do seu período de pós-colheita. Neste trabalho foi desenvolvido um revestimento comestível para aplicar em morangos, a partir de Aloe vera e de quitosano. O primeiro começou a ser estudado como revestimento comestível recentemente, sendo diminuta a bibliografia existente, e nunca foi antes aplicado em morangos. O uso de quitosano como revestimento encontra-se vastamente documentado, com várias aplicações bem sucedidas em frutos frescos. Para atingir os objectivos propostos, foram realizadas diversas simulações, que tiveram lugar em dois momentos temporais distintos. No total, a amostra estudada foi constituída por 27 kg de morangos, tendo sido analisados os parâmetros cor, textura, massa, acidez titulável, teor de sólidos solúveis, carga microbiológica e infecções, associados ao processo degenerativo dos frutos. Os resultados evidenciam o potencial dos materiais utilizados como revestimentos comestíveis na conservação dos morangos. De facto, foi possível retardar significativamente o aparecimento de infecções de origem fúngica, o que se traduz num decréscimo das elevadas taxas de perdas comuns neste fruto. Foram encontrados indícios de melhoria na manutenção das características texturais dos frutos, especialmente ao nível externo e médio interior. Esta manutenção, conjugada com o aumento inesperado da taxa de perdas de água, comprova que a acção dos revestimentos na manutenção da textura vai para além do controlo do turgor celular, sugerindo assim uma acção sobre os processos enzimáticos e/ou metabólicos característicos da degradação da textura dos frutos. Os resultados da quantificação de sólidos solúveis e ácidos mostraram que os materiais utilizados nos revestimentos induziram a um consumo superior de ácidos orgânicos e de polissacarídeos por parte dos morangos, sugerindo uma metabolização energética superior. Ao nível das alterações cromáticas, foram detectadas diferenças, no entanto os resultados não foram conclusivos.
After a fruit is harvested from its mother plant, structural, chemical, nutritional, biochemical and enzymatic changes occur, leading, ultimately, to the senescence period in which the fruit ceases to be edible. To achieve the maintenance of fruits for a longer time, methods and technologies were developed and implemented during the last decades. The application of edible coatings on fruits is one of these methods, which creates a permeable protective barrier on the surface of the fruit, with an inhibitory effect of certain changes characteristic of the period of post-harvest. Through this project, an Aloe vera and chitosan-based coating was developed and applied in strawberries. Aloe vera began to be studied as an edible coating recently, having few studies published, and it has never been applied before in strawberries. The use of chitosan as a coating is widely documented, with several successful applications in fresh fruits. To achieve these objectives, several simulations were carried out, taking place at two different times. In total, the study sample consisted of 27 kg of strawberries and the parameters color, texture, mass, acidity, soluble solids, microbiological growth and infections, associated with the degenerative process of the fruit, were analyzed. The results have shown the potential of the materials used as edible coatings on the storage of strawberries. In fact, it was possible to delay the onset of infections of fungal origin significantly, which lead to a decrease in the high rates of strawberries losses. Evidence of improvement in maintaining the textural characteristics of fruits was found, especially concerning the external and internal medium texture. This maintenance coupled with the unexpected increase in the rate of water loss shows that the action of the coatings in maintaining the texture goes beyond the control of turgor cell, thus suggesting an action on the enzymatic and/or metabolic pathways of texture degradation. The results of the quantification of soluble solids and acids showed that the materials used in coatings induced a higher consumption of organic acids and polysaccharides by strawberries, suggesting a higher energy metabolism. In terms of color changes, differences were detected, however the results were inconclusive.

Previous issue date: 2010Aloe ferox Miller, pertencente à família Liliaceae, é originária da Província do Cabo Oriental na África do Sul. No Brasil, a planta é conhecida como babosa e os maiores produtores encontram-se no interior de São Paulo (particularmente no município de Jarinu), Santa Catarina e na região Nordeste. Sendo esta última, a que possui as melhores condições de plantio. Ela consiste em um arbusto perene arborescente típico de climas secos e quentes, possui folhas alongadas e pontiagudas, e é constituída em duas partes: gel e látex. A resina de Aloe ferox é um resíduo sólido obtido pela evaporação do látex que escorre do corte transversal de suas folhas. Na medicina popular, dentre outras aplicações, a resina da planta é usada no tratamento da constipação. Os efeitos da administração oral de A. ferox foram investigados sobre a fertilidade, prenhez e desenvolvimento pós-natal da prole de ratas Wistar. A aloína presente na resina foi identificada por cromatografia em camada delgada e os derivados hidroxiantracênicos expressos como aloína foram quantificados por espectrofotometria. A resina na forma de pó foi dissolvida em glicerina 40% (v/v). O estudo foi realizado em três períodos, cada um contendo cinco grupos de ratas prenhes (n=8- 9/grupo), totalizando 15 grupos randomicamente formados. Os grupos 1 e 2 (grupos controle) receberam água destilada e solução de glicerina 40% (v/v), respectivamente, enquanto os outros foram tratados oralmente com A. ferox nas doses de 0,1, 0,5 e 2,5 g/kg. No primeiro período, o tratamento foi administrado do 1º ao 6º dia (período de pré-implantação - PP) e o segundo, do 7º ao 14º dia (período de organogênese - PO). No 20º dia de prenhez, as ratas foram laparotomizadas para avaliação dos parâmetros reprodutivos. No último período, as ratas prenhes foram tratadas oralmente com as mesmas doses durante toda a prenhez e os parâmetros maternos e os da prole foram avaliados. A aloína (Rf 0,35) foi identificada e a porcentagem dos derivados hidroxiantracênicos expressos como aloína foi 33.5%. Durante o PP houve diminuição no ganho de massa corporal materna (p < 0,05) em todas as doses. Reduções também foram observadas em alguns parâmetros maternos (massas da placenta) e fetais (comprimento e massa relativa) nas doses de 0,5 e 2,5 g/kg quando comparado aos grupos controle. No PO, a redução no ganho de massa corporal materna foi observada apenas no tratamento com a maior dose. Entretanto, outros parâmetros como massas dos fetos, da placenta e dos ovários foram alterados em todas as doses avaliadas. Durante o período integral da gestação houve aumento apenas na massa corporal e comprimento dos conceptos no 7º e 21º dias de vida pós-natal, na maior dose. Os parâmetros comportamentais da prole não foram alterados. Dessa forma conclui-se que o uso da glicerina como solvente não interferiu nos parâmetros reprodutivos analisados no estudo. Embora alguns parâmetros tenham sido alterados pelo tratamento com A. ferox, o desenvolvimento normal da prole não foi influenciado por ele. Mas, o tratamento com a maior dose de A. ferox sugere possível toxicidade materna devido ao provável efeito abortivo obtido com essa dose, mesmo sem causar morte de ratas prenhes e malformações fetais. Nesse sentido, estudos posteriores devem ser conduzidos a fim de assegurar o uso dessa planta durante a gestação humana

Il principale costituente delle foglie di aloe è il gel di aloe ampiamente utilizzato in diversi settori industriali (cosmetico, medico, alimentare) grazie alle sue caratteristiche chimico-fisiche, tra cui la presenza di polisaccaridi con un’elevata capacità di ritenzione di acqua e sostanze oleose.
L’obbiettivo di questo lavoro di tesi è stato la valutazione della capacità di assorbimento di cinque diverse matrici oleose (olio di mais raffinato, olio di soia raffinato, olio di girasole raffinato, olio extra vergine di oliva, glicerolo) da parte di polisaccaridi ottenuti dalla liofilizzazione di gel di aloe. Il prodotto liofilizzato è stato utilizzato per l’estrazione dei residui insolubili in alcol (AIRs) su cui è stata poi valutata la capacità di assorbimento delle matrici oleose. Per la caratterizzazione delle diverse tipologie di campioni utilizzati, sono state realizzate alcune determinazioni analitiche: per quanto riguarda gli AIRs, è stata realizzata la determinazione degli zuccheri mediante analisi gascromatografica, degli acidi uronici mediante spettrofotometria e del grado di metil esterificazione delle pectine mediante spettroscopia a infrarossi. Nelle matrici oleose è stata invece valutata la composizione in acidi grassi. I dati ottenuti sono risultati in accordo con quanto già presente in letteratura. Non è stato, inoltre, evidenziato un assorbimento selettivo in funzione dei diversi oli vegetali testati.

En el caso de las biopulpectomías que por diversas circunstancias deban de postergar su culminación con una cita adicional, existe una controversia sobre el tipo de medicamento intraconducto entre sesiones a usar. Dentro de ellos las más aceptadas son las pastas de hidróxido de calcio por sus propiedades como antimicrobiano y favorecedor de la reparación tisular, sin embargo, se ha reportado también la toxicidad de esta pasta sobre los tejidos periapicales. Sin embargo, estos efectos pueden ser modulados por el vehículo de la pasta. En esta investigación se propone el gel de Aloe vera como vehículo de la pasta de hidróxido de calcio, ya que posee características fisicoquímicas que pueden disminuir su toxicidad, y por sus propiedades biológicas pueden mejorar la respuesta tisular a la pasta de hidróxido de calcio.
El objetivo de esta investigación fue determinar si existía diferencia en la difusión de los iones hidroxilo y calcio entre las Pastas de Hidróxido de Calcio (HC), para medicación intraconducto, utilizando como vehículo el gel de Aloe vera, y otros vehículos convencionales.
Se prepararon tres pastas de hidróxido de calcio: la Pasta A (HC con gel de Aloe vera), y dos pastas utilizadas como control: la Pasta B (HC con glicerina), y la Pasta C (HC con agua destilada). El diseño experimental elegido fue un modelo in vitro utilizando tubos capilares de vidrio a los cuales se les colocó las pastas de hidróxido de calcio, siendo 10 tubos por cada pasta, colocándolas en frascos de vidrio para cada tubo conteniendo 50 ml de agua deionizada como medio de análisis. El tiempo de experimentación fue de 14 días, realizando las mediciones a las 3, 24, 72, 168 y 336 horas.
Los resultados fueron analizados utilizando las pruebas estadísticas ANOVA One Way, Tukey post hoc, y t-student´s para muestras no pareadas (p<0,01). La difusión iónica de las pastas A, B y C variaron durante el tiempo de experimentación, encontrando una tendencia a mantenerse luego de llegar a un pico de difusión en el medio de análisis. La difusión de iones hidroxilo de la Pasta A fue menor al de la pasta B, a las 3 y 24 horas, mientras que en los demás momentos no hubo diferencia significativa. La difusión de iones hidroxilo de la Pasta A fue menor al de la pasta C, desde las 24 horas hasta las 336 horas. En cuanto a la difusión de iones calcio, no se encontró diferencia estadística significativa sobre la difusión de los iones calcio entre la pasta A y B a las 3, 72, y 168 horas; mientras que a las 24 horas, la pasta A tuvo mayor difusión que la pasta B, y a las 336 horas la pasta A tuvo menor difusión que la pasta B. La difusión de iones calcio de la pasta A fue mayor al de la pasta C a las 24 y 72 horas, mientras que a las 168 y 336 horas la pasta A tuvo menor difusión que la pasta C. Al analizar los vehículos controles, la pasta B presentó casi las mismas características difusionales de la pasta A frente a la pasta C.
La difusión de iones hidroxilo y calcio de las pastas de hidróxido de calcio con el gel de Aloe vera (Pasta A), fue diferente al de las pastas de hidróxido de calcio con los vehículos convencionales (Pastas B y C). El gel de Aloe vera influye la difusión de la pasta de hidróxido de calcio disminuye la difusión de iones hidroxilo y modula la difusión de iones calcio.Endodontic treatment depends on several aspects such as pulp vitality among others. In case of biopulpectomies which must be delayed for several reasons, there is no a general agreement related to the most appropriate type of interappointment intracanal dressing. Among them, one of the most accepted are Calcium Hydroxide pastes owing to their antimicrobial and tissular repair properties. However, toxicity of this paste over periapical tissues have been reported in experimental investigations. In this research Aloe vera gel was proposed as vehicle of Calcium Hydroxide paste because of both its physical-chemical characteristics, which may diminish the toxicity of this paste, and its biological properties, which might improve the tisular response to Calcium Hydroxide paste. The purpose of this research was to determine whether there was difference in the diffusion of hydroxyl and calcium ions between Calcium Hydroxide intracanal dressing using Aloe vera gel as vehicle from other convencionals. Three calcium hydroxide (CH) pastes were prepared: Paste A, CH with Aloe vera gel; Paste B, CH with glycerine; and Paste C, CH with destilated water. The elected experimental design was an in vitro model using capilar glass tubes containing calcium hydroxide pastes, being 10 tubes for each paste. Those tubes were sumerged into individual bottles for each tube, containing 50 ml of deionizated water as analysis medium. Experimental time was 14 days, performing measurements at 3, 24, 72, 168 and 336 hours. Results were analysed using statical tests such as ANOVA One Way, Tukey post hoc and t-test (p<0.01). Ionic diffusion of pastes A, B and C varied during experimental time, finding a tendency to stabilise after reaching a diffusion peak into the analysis medium. Hydroxyl ion diffusion of Paste A was minor than that of Paste B at 3 and 24 hours; whereas at 72, 168 and 336 hours there was no statistically significant difference between them. Hydroxyl ion diffusion of Paste A was minor than that of Paste C from 24 to 336 hours. There was no statistically significant difference of calcium ion diffusion between Pastes A and B at 3, 72 and 168 hours. Although Paste A had more diffusion than Paste B at 24 hours, but it had minor diffusion at 336 hours. There was no statistically significant difference of calcium ion diffusion between Pastes A and C at 3 hours. Calcium ion diffusion of Paste A was greater than that of Paste C at 24 and 72 hours, while it was minor at 168 and 336 hours. Analysing the conventional vehicles, Paste B showed almost same diffusional characteristics of Paste A versus Paste C. Calcium and hydroxyl ions diffusion of Calcium Hydroxide paste with Aloe vera gel (Paste A) was different from those of Calcium Hydroxide pastes using conventional vehicles (Pastes B and C). Aloe vera gel influences on calcium hydroxide paste diffusion by diminishing hydroxyl ions diffusion and modulating calcium ions diffusion.

Abstract
!
The buccal mucosal route offers several advantages
but the delivery of certain drugs can be limited
by low membrane permeability. This study
investigated the buccal permeability properties
of didanosine (ddI) and assessed the potential of
Aloe vera gel (AVgel) as a novel buccal permeation
enhancer. Permeation studies were performed
using Franz diffusion cells, and the drug was
quantified by UV spectroscopy. Histomorphological
evaluations were undertaken using light and
transmission electron microscopy. The permeability
of ddI was concentration-dependent, and
it did not have any adverse effects on the buccal
mucosae. A linear relationship (R2 = 0.9557) between
the concentrations and flux indicated passive
diffusion as the mechanism of drug transport.
AVgel at concentrations of 0.25 to 2%w/v enhanced
ddI permeability with enhancement ratios
from 5.09 (0.25%w/v) to 11.78 (2%w/v) but
decreased permeability at 4 and 6%w/v. Ultrastructural
analysis of the buccal mucosae treated
with phosphate buffer saline pH 7.4 (PBS), ddI/
PBS, and ddI/PBS/AVgel 0.5%w/v showed cells
with normal plasmalemma, well-developed cristae,
and nuclei with regular nuclear envelopes.
However, cells from 1, 2, and 6%w/v AVgel-treated
mucosae showed irregular nuclear outlines, increased
intercellular spacing, and plasmalemma
crenulations. This study demonstrates the potential
of AVgel as a buccal permeation enhancer for
ddI to improve anti-HIV and AIDS therapy.

Full textAbstract:
Apparent recent population contractions at Aloe dichotoma’s equatorward range limit have led this
iconic arborescent succulent to be cited as one of the first biological indicators of the impact of
anthropogenic climate change in southern Africa. However, prior evidence from historical photography of populations as well as detailed botanical field notes indicated that mortality was already pervasive in the southern and central distribution of the species within the first half of the 20th century. This, as well as possible previous assumptive and interpretive problems prompted a reassessment of the evidence for A. dichotoma’s promotion as a climate change indicator species. In the current study, a framework for assessing species vulnerability to climate change was used to determine A. dichotoma’s exposure, sensitivity, and adaptive capacity to climate change impacts. First I evaluated A. dichotoma’s exposure to climate change by independently assessing historical rainfall and temperature records of the longest possible duration, and specific to A. dichotoma’s distributional extent, in order to evaluate how average conditions and temporal trends might contribute to demographic patterns. I then made use of very high spatial resolution demographic information collected during a roadside mega-transect in order to re-examine the merits of a latitudinal cline in mortality. Subsequently, I related demographic patterns to a detailed contemporary climate surface in order to gauge the strength of the relationship between the two, as well as to determine the relative sensitivity of juvenile and adult life history stages. Additionally, with the aid of detailed population-level sampling and averaged solar radiation values for opposing aspects, I investigated A. dichotoma’s adaptive capacity in terms of its ability to recruit to more favourable aspects. In this respect, a new technique was developed to determine the approximate time since death of in situ skeletons, as well as the age classes from which they were derived. Lastly, study results were interpreted in relation to A. dichotoma’s life history traits to determine the likelihood of a recent response to climate change Despite a paucity in instrumental records and record length, particularly within the equatorward summer rainfall zone (SRZ), encompassing southern and central-western Namibia, historical climate analyses revealed considerable spatial and temporal variability in temperature and, especially, rainfall, within the distribution range of the species. For the SRZ, average climatic conditions were found to be at least as severe within the Gariep River valley, between 28°S and 29°S, as for the equatorward extreme at approximately 21°S, undermining previous inferences of a simple latitudinal climate gradient. Conversely, average rainfall within the poleward winter rainfall zone (WRZ), and south-western extreme of the SRZ, was shown to have been historically higher and more consistent than the SRZ to the north. The natural climatic disjunction between northern and southern rainfall zones has likely had a significant influence on the maintenance of relative latitudinal recruitment and mortality rates in A. dichotoma, and may have contributed to an erroneous attribution of observed mortality to recent, anthropogenic climate change. Historical temperature records indicated an almost uniformly increasing trend throughout the distribution, rising more rapidly within the SRZ. However, rainfall trends were more difficult to interpret, being strongly contingent upon record length, segment of time recorded, and initial and terminal conditions under which the record was established. These interpretive difficulties were considerable for Namibian stations, and advocated a cautious interpretation of negative rainfall trends at several summer rainfall stations, while generally more robust records at winter rainfall stations registered mostly positive trends over the last sixty years. Results from the roadside mega-transect corroborated trends in climatic severity, indicating that proportional mortality had also been greatest within the Gariep River valley between 28°S and 29°S and not at the equatorward range limit as previously suggested. Furthermore, there was only a very weak relationship between age classes and key contemporary climate variables, which suggested an uncoupling between the two. Despite generally poor relationships, juveniles were most responsive to climate and solar radiation gradients, suggesting a greater sensitivity compared to the adult age class, which appeared more resilient. In addition, most mortality was shown not to be recent in origin, but to have occurred several decades ago and to be chiefly derived from larger and, therefore, more climatically-resilient, adult age class rather than smaller, more climatically-sensitive juvenile individuals. In combination with A. dichotoma’s life history traits, including longevity, slow growth and infrequent recruitment, the findings from this study indicate that current demographic patterns reflect longer-term climatic fluctuations rather than recent climate change and that certain climatically marginal populations may be biological relicts of a previously more amenable climate. These findings challenge the view that A. dichotoma has responded negatively to recent, anthropogenically-driven changes in climate and reassert the importance of longer term climatic and demographic processes in shaping patterns currently observed within populations of this species. Coupled with the establishment of a long term ecological research network at key populations spanning the full latitudinal (and longitudinal) range, a greater focus on the regeneration niche and physiological thresholds would help advance our understanding of A. dichotoma’s susceptibility to moisture and temperature deficits arising from climate change. Assessment of the suitability of A. dichotoma as a sentinel of climate change would also be greatly aided by the improved temporal and spatial resolution of historical and palaeo-climatic records within southern Africa. There is an urgent need for this work in the face of possible lagged responses to environmental change within long-lived, infrequently recruiting species, as well as rapidly rising temperatures and uncertainty surrounding future precipitation in the region.

Resultados: O grupo 1 teve diminuição significativa da dor, em ambos os trapézios, com a END, entre todos os momentos de avaliação mas apenas aumento significativo no limiar de dor no trapézio direito entre a 1ª e última avaliação. O grupo 2, quer na END quer no limiar teve melhorias significativas a partir da 5ª sessão em ambos os trapézios. No entanto, em nenhum momento, houve diferenças entre grupos. Conclusão: As duas técnicas testadas apresentaram-se eficazes na diminuição da perceção de intensidade da dor e o aloé vera contribuiu mais para o aumento de tolerância ao limiar de dor em ambos os lados do trapézio superior.
Purpose: To evaluate the pain of the latent trigger points of the upper trapezius, on individuals submitted with an ultrasound (US) treatment with aloe vera or with common gel. Methods: 24 individuals, with an average of ages of 23,44 years, where randomly assigned into two groups, but due to 8 withdrawals, 7 stayed in the group using the common gel (group 1) and 9 in the group US using aloe vera (group 2),. US’s were applied bilaterally on the latent trigger points of the upper trapezius, throughout 10 sessions, in the space of 2 weeks. The pain intensity was evaluated, using a numeric pain scale (NPS) and the pain threshold using a pressure algometer before the first session and after the 5th and the 10th session. Results: Group 1 had a significant diminish of pain, of both trapezius, with NPS, but a higher pain threshold of the right trapezius between the first and last evaluation. In group 2, only from the 5th session that significant enhancements where observed with NPS and by the threshold, on both trapezius. However, at no point there were differences between groups. Conclusion: The two techniques that we tested were effective for diminishing the perception of the pain intensiveness, and aloe vera contributed for a higher tolerance of the pain threshold on both sides of the upper trapezius.

The jiboias (Boa constrictor) are tropical snakes that can present an average length of 3.5 m, occupying most of the Brazilian biomes. It is one of the most common snake species found in zoological collections in Brazil, being used as a tool for environmental and leisure education. The maintenance of these animals in captivity, associated with management errors, predisposes to the appearance of cutaneous lesions that, if not treated, can compromise the health and / or quality of life of these animals. Thus, the importance of identifying and developing the best agents for healing is hoped that they will be preferentially accessible and inexpensive, like some herbal medicines. This study followed the cicatrization of aloe vera, EB1 and EB2, gel and total leaf, respectively, in 12 jiboias (Boa constrictor), by means of macroscopic daily evaluations, for 40 consecutive days. Appearance of the wound in terms of color, gloss, crust formation and exudation. The obtained data evidenced differences in relation to the control group, demonstrating the effect of this phytotherapic on the cicatrisation
As jiboias (Boa constrictor) são serpentes tropicais que podem apresentar um comprimento médio de 3,5 m, ocupando a maioria dos biomas brasileiros. É uma das espécies de serpentes mais encontradas em coleções de zoológicos no Brasil, sendo utilizada como ferramenta de educação ambiental e lazer. A manutenção desses animais em cativeiro, associado a erros de manejo, predispõe ao aparecimento de lesões cutâneas que, se não forem tratadas, podem comprometer a saúde e/ou a qualidade de vida desses animais. Destaca-se assim, a importância de identificar e desenvolver os melhores agentes promotores da cicatrização, esperando que eles sejam preferencialmente de fácil acesso e baixo custo, como alguns fitoterápicos. Diante disso, este estudo acompanhou o efeito cicatrizante de extratos hidroalcóolicos da babosa (Aloe vera), EB1 e EB2, gel e folha total respectivamente, em 12 jiboias (Boa constrictor), através de avaliações macroscópicas diárias, durante 40 dias consecutivos, quanto ao aspecto da ferida em termos de cor, brilho, formação de crosta e exsudação, além de análises histológicas a cada 5 dias. Os dados obtidos evidenciaram diferenças em relação ao grupo controle, demostrando o efeito desse fitoterápico sobre a cicatrização

Products derived from Aloe vera are popular around the world due to their medicinal properties, including immunostimulatory, and represent potentially an inexpensive alternative for the control of fish diseases. The purpose was to evaluate A. vera effects in stress and innate immune responses of pacu (Piaractus mesopotamicus), fish of economic value in Brazilian farming. Fish were fed, for 10 days, with four diets: control diet, and diets with 5 g kg-1 (0.5%), 10 g kg-1 (1%) and 20 g kg-1 (2%) of A. vera. Thereafter, fish were transported for 4 hours (166 g L-1) (Experiment 1) and then experimentally infected with Aeromonas hydrophila or injected with PBS buffer (sham), by intraperitoneal via (IP) (Experiment 2). Fish were sampled at the initial condition (before transport, n=10), transport arrival (n=11), 12 and 24 hours after transport without IP (Recovery; n=8) and also at 12 and 24 hours after transports with IP (Challenge; A. hyd. or PBS, n=8). Transport increased the cortisol and glucose levels and reduced the leukocyte respiratory burst (LRB) and hemolytic activity of alternative complement pathway (ACH) of control fish, while A. vera prevented the LRB and ACH reduction at arrival. Serum lysozyme concentration (SLC) increased at 24 h after transport in A. vera infected fish. LRB, SLC and ACH of fish feeding A. vera (2%) were significantly higher, 24 h after the bacterial infection, than in control fish. A. vera enhanced the innate immune responses tested in pacu and reinforces the possibility for medicinal herbs added to fish food as an alternative method to prevent diseases in fish

Hoy en día los consumidores buscan alimentos naturales que aporten una mayor cantidad de beneficios al organismo. En respuesta a esta búsqueda del consumidor, la industria alimentaria se está enfocando en desarrollar alimentos que incluyan en sus ingredientes mayor cantidad y variedad de frutas, hortalizas, hasta plantas que usaban nuestros antepasados por sus beneficios.
Debido a esto, el objetivo principal del presente trabajo fue elaborar un helado de agua, incorporando como ingredientes jugo de uva de distintas variedades y gel de Aloe sp, buscando satisfacer a los consumidores en cuanto al incremento en la demanda de alimentos más sanos, naturales y que aporten beneficios al organismo.
Se llevaron a cabo pruebas de elaboración con variedades de uva Bonarda y Malbec, donde se probaron diferentes proporciones del jarabe base (50-60%) y de la mezcla jugo de uva/gel de Aloe sp. (40-50%). Luego de obtener las formulaciones, para cada variedad de uva se realizaron elaboraciones con las diferentes proporciones de gel de aloe (mezcla con 50% y 60% de gel de aloe / 50 y 40% de jugo de uva). Listas las elaboraciones, se realizaron los análisis microbiológicos que detalla el Código Alimentario Argentino en su artículo 1078, para comprobar la aptitud de consumo de los helados. También se realizaron análisis de Proteínas, Hidratos de Carbono, Grasas totales, Grasas saturadas, Grasas trans, Cenizas, Humedad, Sodio, Valor energético, para determinar la composición centesimal de cada producto. Una vez obtenida la aptitud para consumo de los helados, se realizó primero una evaluación sensorial con 17 jueces semi-entrenados, que además determinaron la aceptación de cada variante elaborada. Luego se realizaron pruebas de aceptación y preferencia de las variantes, por 63 consumidores.
En cuanto a los resultados obtenidos se puede decir que según los análisis microbiológicos los helados resultaron aptos para consumo, sin embargo, debe mejorarse el tratamiento de las materias primas para reducir el recuento de levaduras y mohos del producto final. Los análisis nutricionales mostraron que las formulaciones elaboradas no aportan cantidades significativas de proteínas ni de fibra alimentaria, tampoco aportan cantidades significativas de sodio ni de grasas saturadas lo que es bueno ya que el exceso de estos ocasiona problemas en la salud. Según las evaluaciones realizadas, las cuatro formulaciones fueron aceptadas, sin embargo, las que más gustaron fueron las muestras que tenían mayor proporción de jugo de uva Malbec y Bonarda y menos de gel de aloe.Fil: Rabino, Gabriela Elisa.

The purpose was to evaluate A. vera effects in stress and innate immune responses of pacu (Piaractus mesopotamicus), fish of economic value in Brazilian farming. Fish were fed, for 10 days, with four diets: control diet, and diets with 5 g kg-1 (0.5%), 10 g kg-1 (1%) and 20 g kg-1 (2%) of A. vera. Thereafter, fish were transported for 4 hours (166 g L-1) (Experiment 1) and then experimentally infected with Aeromonas hydrophila or injected with PBS buffer (sham), by intraperitoneal via (IP) (Experiment 2). Fish were sampled at the initial condition (before transport, n=10), transport arrival (n=11), 12 and 24 hours after transport without IP (Recovery; n=8) and also at 12 and 24 hours after transports with IP (Challenge; A. hyd. or PBS, n=8). Transport increased the cortisol and glucose levels and reduced the leukocyte respiratory burst (LRB) and hemolytic activity of alternative complement pathway (ACH) of control fish, while A. vera prevented the LRB and ACH reduction at arrival. Serum lysozyme concentration (SLC) increased at 24 h after transport in A. vera infected fish. LRB, SLC and ACH of fish feeding A. vera (2%) were significantly higher, 24 h after the bacterial infection, than in control fish. A. vera enhanced the innate immune responses tested in pacu and reinforces the possibility for medicinal herbs added to fish food as an alternative method to prevent diseases in fish
