The reproductive health of individuals is severely compromised by HIV infection, with candidiasis being the most prevalent oral complication in patients. Although not usually associated with severe morbidity, oropharyngeal candidiasis can be clinically significant, as it can interfere with the administration of medications and adequate nutritional intake, and may spread to the esophagus. Azole antifungal agents are commonly prescribed for the treatment and prophylaxis of candidal infections. However, the emergence of drug resistant strains and dose limiting toxic effects have complicated the treatment of candidiasis. Consequently, safe and effective and affordable medicine is required to combat this fungus. Commercial garlic (Allium sativum) has been used time since immemorial as a natural antibiotic, however very little is known about the antifungal properties of two indigenous South African species of garlic, namely Tulbaghia alliacea and Tulbaghia violacea, that are used as folk medicines for a variety of infections. This study compares the in vitro anti-candidal activity of Tulbaghia alliacea, Tulbaghia violacea and Allium sativum extracts. It was found that the greatest concentrations of inhibitory components were extracted by chloroform or water. The IC50 concentrations of Tulbaghia alliacea were between 0.007 &ndash
0.038% (w/v). Assays using S. cerevisiae revealed that the T. alliacea extract was fungicidal, with a killing half-life of approximately 2 hours. This inhibitory effect of the T. alliacea extracts was observed via TLC, and may be due to an active compound called Marasmicin, that was identified using NMR. This investigation confirms that extracts of T.alliacea exhibit anti-infective activity against candida species in vitro.

In South Africa, the crude aqueous extract from Hypoxis hemerocallidea is used by AIDS patients to treat opportunistic infections, such as tuberculosis. The rapid emergence of multidrug-resistant tuberculosis, and extreme drug resistant tuberculosis, in recent years, is a major threat to human health. The treatment of TB, nosocomial bacterial infections, and fungal infections is now a clinical challenge, especially in the immuno-compromised individual. There is a dire need for novel antibiotic alternatives with phytotherapies and plant-derived compounds as potentially promising alternatives. The main objective of this study was to investigate the antimycobacterial activity of Hypoxis hemerocallidea, a South African medicinal plant, using Mycobacterium smegmatis.

Der volle Inhalt der QuelleAnnotation:
Previous research into complementary and alternative medicine has failed to accord each form of alternative medical intervention individual significance. This research considers medical herbalism in Britain and investigates the re-presentation of its knowledge within a scientific framework as a strategy in a process of professionalisation. Data were gathered from herbalists' own statements that provided the answers to how? and why? this occurred. Whilst it is suggested that much science is heavily influenced by its social and cultural enviromnent, the tenacious portrayal of biomedicine as science is taken as accepted orthodoxy. Dolby's model, whereby unorthodox science assumes the features of orthodox science to become accepted as science, is forwarded as an explanation of how herbal medicine has been re-presented as phytotherapy and therefore 'scientific'. The influences of the sociocultural enviromnent and the sociopolitical enviromnent on herbalism's recognition and acceptance by both the state and conventional medicine are suggested as explanations of why phytotherapy has been promoted by some herbalists. It is noted that such transformative measures have not radically affected the professional practice of medical herbalists, nor are they universally welcomed. The anomaly between institutional education of herbalism in terms of phytotherapy and the continuing practice of herbalism as a 'tradition' is noted. The relative identities of practitioners - with a cultural identity - and herbal institutions - with a social identity - is suggested as the explanation for the discontinuity between institutional knowledge and actual practice. It is also argued that medical herbalists have an element of altruism in their practice that is noteworthy beyond an assumed professional service orientation. Herbalists' differences of view regarding the acceptability of promoting phytotherapy as a route to recognition and acceptance appear to be subordinated by fears and anxieties about possible future govermnent legislation and EU harmonisation regulations.

A asma é uma doença crônica das vias aéreas responsável por significativa morbidade e mortalidade mundial. Medicamentos anti-inflamatórios, tais como os corticosteróides, são algumas das opções de tratamento mais importantes, no entanto, elas podem causar efeitos secundários indesejáveis. Historicamente, as plantas foram uma fonte principal de moléculas com atividade biológica. O objetivo deste estudo foi avaliar o efeito do MC, um extrato vegetal brasileira com propriedades anti-inflamatórias, no tratamento da asma em um modelo animal. Métodos: Camundongos machos Balb/C, com idade de 5 a 6 semanas, foram sensibilizados com ovalbumina (OVA) por via intraperitoneal (IP) por duas vezes, com uma semana de intervalo, e desafiados diariamente com OVA intranasal durante três dias. Os animais foram tratados diariamente com a MCA (aquoso) MCHA (hidroalcóolico) na dose 500 mg/kg ip por três dias, durante os desafios. Os camundongos do grupo controle receberam solução salina nos mesmos dias. Cinco a oito animais por grupo foram utilizados. Vinte e quatro horas após o último desafio, os ratinhos foram ventilados com um respirador animal pequeno (FlexiVent®), e foram realizadas medições in vivo da hiperreactividade brônquica com concentrações crescentes de metacolina em aerossol (6,25, 12,5, 25 e 50 mg / ml). Os parâmetros avaliados e comparados foram: a resistência total (RRS), elastância total (ERS), resistência do tecido (G) e elastância tecidual (H). Após ventilação, foi colhido lavado broncoalveolar (LBA) para análise da contagem de células totais e diferenciais. Interleucinas inflamatórias (IL-4, IL-5, IL-10, IL- 13, IFN-?) foram analisadas no homogenato pulmonar além da dosagem sérica de IgE antiOVA. Os pulmões dos animais foram coletados para análise histológica (H&E). Resultados: O tratamento com extrato MCHA reduziu significativamente a hiperresponsividade brônquica através da mensuração das medidas RRS (p<0,001), ERS (p<0,05), G (p<0,05) and H (p<0,001), quando comparado com o grupo de animas asmáticos não tratados. Extratos de MCA e MCHA reduziram tambem significativamente células totais (p<0,05) e contagem de eosinófilos (p<0,05). MCHA reduziu a concentração de IFN-? (p<0,01) quando comparado aos animais asmáticos não tratados. MCA (p<0,001) mostrou uma significativa redução do número de células inflamatórias por área quando comparado ao grupo asmático não tratado. Conclusão: Os dois extratos (aquoso e hidroetanólico) das folhas da espécie Momordica charantia L., na dose de 500 mg/kg, foi eficaz no tratamento da asma em modelo animal induzido por ovalbumina tanto em medidas da mecânica pulmonar quando em marcadores inflamatórios e estudo histológico, sendo o extrato hidroetanólico potencialmente mais eficaz na dose estudada.Asthma is a chronic disease of the airways responsible for significant morbidity and mortality worldwide. Anti-inflammatory medications, such as corticosteroids, are some of the most important treatment options, however they can cause undesirable side effects. Historically, plants have been a major source of molecules with biological activity. The objective of this study was to evaluate the effect of MC, a Brazilian herbal extract with anti-inflammatory properties, on asthma treatment in an animal model. Methods: Male Balb/c mice, 5 to 6 weeks, were sensitized twice with ovalbumin (OVA) intraperitoneally (ip), one week apart, and challenged daily with OVA intranasally for three days. Mice were treated daily with MCA (aqueous) MCHA (hydroethanolic) extract (500 mg/kg) ip for three days, during challenges. Control mice received saline on the same days. Five to eight mice were utilized per group. Twenty-four hours after the last challenge, mice were ventilated with a small-animal ventilator (FlexiVent®), and in vivo measurements of bronchial hyperresponsiveness were performed with increasing concentrations of methacholine aerosol (6.25, 12.5, 25 and 50 mg/ml). The following parameters were evaluated and compared: total resistance (RRS), total elastance (ERS),, tissue resistance (G) and tissue elastance (H). After ventilation, was collected bronchoalveolar lavage (BAL) for analysis of total and differential count inflammatory cells. Interleukins (IL-4, IL-5, IL-10, IL-13, IFN-?) were analyzed in lung homogenate. Morover serum anti-OVA IgE were dosage. The lungs of the animals were collected for histological analysis (H & E) Results: Treatment with MCHA extract significantly decreased airway hyperresponsiveness, measured by RRS (p<0,001), ERS (p<0,05), G (p<0,05) and H (p<0,001), when compared to OVA-challenged mice. MCA e MCHA extract also significantly reduced BAL total cell (p<0,05) and eosinophil counts (p<0,05). MCHA reduced IFN-? concentration (p<0,01) as compared to the untreated group asthmatic. MCA (p<0,001) showed a significant reduction in the number of inflammatory cells per unit area in the air compared to the asthmatic untreated group. Conclusion: The administration of MCA and MCHA from the leaves of Momordica charantia L. species, at a dose of 500 mg / kg was effective in the treatment of asthma in animal models induced by ovalbumin in both pulmonary mechanics measurements as inflammatory markers, and histological study, and potentially more effective MCHA extract the studied dose.

Drosophila melanogaster (Dm) is a valuable genetic model for exploring molecular, genetic and cellular aspects of neurodegeneration in Parkinson's disease (PD), for further understanding its etiology and pathogenesis and making valid contributions to drug screening.
This study used two loss-of-function Dm mutants, PINK1B9 and LRRK2WD40 (deletion of WD40 domain), that both express essential phenotypic characteristics of PD in humans, albeit with a different biochemical mechanism and pathways. Since therapeutic treatments to limit the onset of PD are not yet available and the common approach to treating patients is to intervene by relieving symptoms, I sought to investigate the effects of two natural methanolic extracts of Mucuna pruriens (Mpe; a L-Dopa-containing herbal) and Withania somnifera Dunal (Wse). Both plants have been known and used for centuries in Ayurvedic medicine for their anti-oxidant, anti-inflammatory properties and protective features against neurodegeneration.
The two extracts were tested on both male mutants at different concentrations and different physiological states (as adult L-/A+ or as larvae and adult L+/A+). The parameters considered were lifespan, motor activity, olfactory response, synaptic protein expression, mitochondria and synaptic active zone morphology; both in treated and untreated flies. The overall results indicate that Mpe shows a significant effect on PINK1B9 mutants while Wse acts mostly on LRRK2WD40 ones. The two phytochemical extracts tested were able to counteract the motor and non-motor dysfunctions as well as the mitochondrial impairment, although to different extents depending on PD variance (Mpe-PINK1B9 vs Wse-LRRK2WD40). Additional investigations are necessary to further understand the specific characteristics of the different effects in the two types of mutants.
In detail: a) the administration of 0.1% Mpe L+/A+ on PINK1B9 significantly extended lifespan, overcame the olfactory deficit and improved climbing behavior of the PD mutant. Furthermore, TEM analysis of antennal lobes and thoracic ganglia revealed that Mpe administration prevented the loss of synaptic active zones (T-bars) and reduced the number of damaged mitochondria. Lastly, western blot analysis showed restored bruchpilot (BRP) and tyrosine hydroxylase (TH) expression, referred to WT control levels. The results highlight multiple sites of action of Mpe and suggest that its effects cannot depend only upon its L-Dopa content; b) the effect of 1% Wse L-/A+ administration on LRRK2WD40 caused a recovery of dysfunctions in locomotor activity, in muscle electrophysiological response to stimuli and in mitochondria degeneration. In contrast, the administration of Wse to Dm LRRK2WD40 as L+/A+, independent of the concentration, worsened lifespan and determined the appearance of increased endosomal activity in the thoracic ganglia.
In conclusion, this study strengthens the relevance of using PINK1B9 Dm and LRRK2WD40 Dm as a translational model in studying the properties of both Mucuna pruriens and Withania somnifera for PD treatment.

O emprego de plantas medicinais para o tratamento, cura e preven??o de patologias ? um h?bito que acompanha a humanidade desde seus prim?rdios. Considerando que o Brasil apresenta uma grande biodiversidade para a produ??o de fitoter?picos, ? de suma import?ncia o estudo de plantas como fontes alternativas de tratamento, visando a busca de susbt?ncias que possam auxiliar os f?rmacos atualmente prescritos na terap?utica cl?nica. Durante muitos anos, doen?as cardiovasculares e doen?as tromboemb?licas tem sido as principais causas de morte por doen?as no mundo, sendo respons?veis pela morte de cerca de 17,5 milh?es de pessoas at? o ano de 2012 (31% das mortes em todo o mundo). O sistema de coagula??o est? centralmente envolvido na forma??o do trombo venoso. Indica??es atualmente definidas para anticoagulantes incluem a profilaxia e tratamento do tromboembolismo. Heparinas n?o fracionadas e heparinas de baixa massa molar s?o utilizadas como medicamentos anticoagulantes, no entanto, estes compostos s?o acompanhados de alguns efeitos secund?rios, tais como, trombocitopenia e um elevado risco de hemorragia. A efeito deste problema tem se gerado uma procura de novas subst?ncias, a fim de auxiliar a terap?utica anticoagulante. Neste contexto, este estudo teve como objetivo avaliar o potencial anticoagulante, efeitos t?xicos e hemorr?gicos dos extratos foliares de Licania rigida Benth e Turnera subulata, esp?cies vegetais amplamente encontradas no semi?rido nordestino. Os extratos foram obtidos a partir de etanol (50%), com posterior parti??o com solventes de polaridades crescentes, incluindo hexano e acetato de etila. A avalia??o dos extratos frente ao sistema de coagula??o mostrou uma atividade anticoagulante satisfat?ria pelo Tempo de Tromboplastina parcial Ativada e Tempo de Protrombina (100% de atividade), atividade Anti-Xa (~ 40% de inibi??o) e uma grande capacidade de inibibir diretamente da trombina (~ 80 a 100% de inibi??o) como principal mecanismo de a??o. Al?m disso, observou-se que os extratos apresentam um baixo efeito hemorr?gico, bem como, a aus?ncia de toxicidade em modelos in vitro (Citotoxicidade por MTT) e in vivo (Toxicidade oral aguda). Este trabalho relata pela primeira vez o potencial anticoagulante de Licania rigida Benth e Turnera subulata.
The use of medicinal plants for the treatment, cure and prevention of pathologies is a habit that accompanies humanity since its beginnings. Considering that Brazil presents a great biodiversity for the production of phytotherapics, it is of paramount importance the study of plants as alternative sources of treatment, aiming at the search for substances that may help the drugs currently prescribed in clinical therapeutics. Over many years, cardiovascular disease and thromboembolic disorders have been the leading cause of death by disease in the world, being responsible for the death of approximately 17.5 million people by the year 2012 (31% of deaths worldwide). The coagulation system is centrally involved in the formation of venous thrombus. Currently defined indications for anticoagulants include prophylaxis and treatment of thromboembolism. Unfractionated heparins and low molecular heparins are used as anticoagulant drugs. However, these compounds are accompanied by several side effects such as thrombocytopenia and a high risk of systemic bleeding. The effect of this problem demanded the search for new substances in order to assist prolonged anticoagulant therapy. In this context, this study aimed to evaluate the anticoagulant potential, toxic and hemorrhagic effects from Licania rigida Benth and Turnera subulata leaves, species widely found in Northeast semiarid. The extracts were obtained from ethanol (50%) with subsequent partition with solvents of increasing polarities, including hexane and ethyl acetate.The crude extracts were obtained from ethanol (50%) and subsequent partition with increasingly polar solvents including hexane and ethyl acetate. The evaluation of the extracts against the coagulation system showed a satisfactory anticoagulant activity by Activated Partial Thromboplastin Time and Prothrombin Time (100% activity), Anti-Xa activity (~ 40% inhibition) and a large capacity to inhibit directly from Thrombin (~ 80 to 100% inhibition) as the main mechanism of action. In addition, the extracts were found to have a low hemorrhagic effect, as well as the absence of toxicity in in vitro models (MTT cytotoxicity) and in vivo (acute oral toxicity). This paper reports for the first time the anticoagulant potential of Licania rigida Benth and Turnera subulata.

ATCC strains of Candida spp. Were used for antifungal tests, and ATCC strains of Enterococcus faecalis, Staphylococcus aureus, Staphylococcus epidermidis, Streptococcus mutans and Pseudomonas aeruginosa were used for the antibacterial tests. For the antimicrobial activity, the values of the Minimum Inhibitory Concentration (MIC) and the Minimal Microbicidal Concentration (CMM) of the extracts were determined by the microdilution method in broth, according to Clinical and Laboratory Standards Institute (CLSI). The microorganisms that presented CMM were selected for the biofilm tests, in which it was prepared on a 96-well plate bottom for 48 h. After the biofilms were treated for 5 min. Using the concentrations of 200, 100 and 50 mg of the extracts. To measure the biomass, the Violet Crystal test (CV) was used, and the MTT test was used to evaluate the metabolic activity. Cytotoxicity was assessed on human gingival fibroblasts (FMM-1) using the same treatment parameters used for biofilm tests. Cell viability was evaluated by the MTT, neutral red and violet crystal tests. The data obtained normal distribution and were analyzed by ANOVA and Tukey test, with significance of 5%. The extract of P. paniculata showed antifungal action in biofilms, with average reductions of 29.4 and 42.7% in CV and MTT tests; The antibacterial action was restricted to S. mutans and P. aeruginosa with mean reductions of 15.7 and 28.6% in the respective tests. The extract of J. regia also demonstrated antifungal action with an average reduction of 22.2% in biomass and 31.4% in metabolic activity. The antimicrobial action was restricted to P. aeruginosa with mean reductions of 17.7 and 15.6%,....(Resumo completo, clicar acesso eletrônico abaixo)

Resumo: Tem-se demonstrado que espécies de Candida podem também ser encontradas no biofilme oral, co-agregadas ou aderidas a espécies bacterianas ali presentes, preferencialmente à espécies de Estreptococos, como também há adesão destas leveduras às células do epitélio e aos aparatos protéticos (neste caso é muito comum que pacientes portadores de próteses sejam alvos para as infecções fúngicas). Assim, a habilidade das espécies de Candida para formar biofilme em dispositivos médicos tem ampliado a capacidade de causar doenças assim como a capacidade de resistir a antifúngicos. Por outro lado nas ultimas décadas, tem se observado um crescente interesse nas medicinas alternativas e nas terapias naturais, justificando o aumento significativo de pesquisas nessa área ampliandose no presente. O objetivo desta pesquisa é, primeiramente, avaliar a interação das espécies de Candida albicans, C. tropicalis e C. glabrata em biofilmes préformados por espécies de Streptococcus oralis, S. sanguis, S. mitis, S. mutans e Staphylococcus aureus em diferentes materiais protéticos como: titânio e resina acrílica, e, secundariamente, testar a ação de alguns extratos fitoterápicos como a Mentha piperita, Cymbopogum martinii e Cympopogum winterianus através da concentração mínima inibitória (CMI), na inibição da co-agregação das espécies de Candida spp. a estes microrganismos. Os dados obtidos nesta pesquisa demonstram que as espécies de Candida albicans desenvolvem biofilme sobre os biofilmes pré-formados das bactérias testadas independentemente do material avaliado. A presença de bactérias se demonstra determinante para o desenvolvimento de biofilme por espécies de Candida. A inibição de Candida spp. pelos extratos vegetais testados se mostrou parcial e semelhante quando comparadas, ao lado de se revelarem substâncias potencialmente antifúngicas
Abstract: Candida spp. have been demonstrated found in the oral biofilm, coaggregated or adhered to oral bacteria, especially Streptococcus spp., also too the adhesion of these yeast to mucosal cells and prosthetic devices (in this case is common that patients that carry a prosthetic device, could be targets to fungal infections). The ability of Candida spp. to form biofilm on medical devices has extended the capacity to cause diseases and to resist antifungal agents. The lasts decades, have been observed big interest concern to medicinal plants and natural therapies, justifying the significant increase of research on the area in the present. The aim of this research was firstly, evaluate the interaction of C. albicans, C. tropicalis and C. glabrata on S. oralis, S. sanguis, S. mitis, S. mutans and Staphylococcus aureus preformed biofilm in different prosthetics materials like titanium and acrylic resin. Secondly, was evaluated the action of some vegetal extracts like Mentha piperita, Cymbopogum martinii and Cympopogum winterianus, using the Minimal Inhibitory Concentration (MIC), against the Candida spp. coaggregation with these microorganisms. The data obtained in this research show that Candida spp. develop biofilm on preformed bacterial biofilm, independently of tested material. Bacterias are determinant to Candida spp. biofilm development. The Candida spp. inhibition for vegetal extract was partial and equal when compared, revealing itself like potentially antifungal substances

Resumo: O parasitismo por Rhipicephalus (Boophilus) microplus ocasiona grandes perdas econômicas nos rebanhos bovinos, e seu controle por meio de carrapaticidas sintéticos enfrenta problemas de resistência, além do risco de resíduos nos alimentos e ambiente. Com o objetivo de contribuir com informações relevantes para o controle desse parasita, o presente estudo teve três objetivos: 1) avaliar in vitro o efeito do óleo essencial de Ocotea elegans "canela-sassafrás" sobre larvas e fêmeas ingurgitadas de R. (B.) microplus; 2) avaliar medicamento homeopático no controle de infestações naturais; 3) comparar as técnicas de estimativa visual e de quantificação por amostragem de larvas eclodidas no teste de imersão de fêmeas adultas, visto a importância dessas no levantamento de substâncias com ação carrapaticida. No primeiro experimento "Efeito acaricida e repelente in vitro do óleo essencial de Ocotea elegans (canela-sassafrás) sobre Rhipicephalus (Boophilus) microplus", foram adotados os testes: contato de larvas em papel impregnado (LPI), teste de repelência larvar (TR) e imersão de fêmeas adultas (AIT). A fim de verificar a eficácia, O. elegans foi avaliada nas concentrações de 0,78 mg/mL a 100 mg/mL. No AIT, a partir da concentração de 25 mg/mL, a eficácia foi superior a 90%. Os LPI (48h) a 100 mg/mL resultaram em taxas de mortalidade acima de 70%. Já o TR obteve repelência superior a 80% a partir da menor concentração avaliada. Em relação às concentrações letais (CL), a menor CL50 ob... (Resumo completo, clicar acesso eletrônico abaixo)
Abstract: The parasitism by Rhipicephalus (Boophilus) microplus causes large economic loss in cattle herds and its control through chemical acaricides faces problems of resistance and residues in food and in the environment. Aiming to contribute with relevant information for the control of this parasite, the present study had three objectives: 1) evaluate the effect in vitro of Ocotea elegans essential oil on larvae and engorged females of R. (B.) microplus, 2) evaluate homeopathic medicine to control R. (B.) microplus natural infestations, and 3) compare visual estimation and quantification by sampling techniques of larvae hatching in the engorged females immersion test, due to the importance of this technique in the screening of substances with antiparasitic action. In the first experiment, "In vitro acaricidal and repellent effect of Ocotea elegans essential oil on R. (B.) microplus", were adopted the tests: larval packet test (LPT), the larval repellency test (RT) and the adult immersion test (AIT). In order to verify efficacy, O. elegans was evaluated at concentrations of 0.78 mg/mL to 100 mg/mL. In the AIT, from the concentration of 25 mg/ml, the efficacies were higher than 90%. LPT (48h) at 100 mg/mL resulted in mortality rates higher than 70%. The RT obtained repellency higher than 80% sice the lowest concentration evaluated. In relation to the lethal concentrations, the lowest LC50 obtained in the LPT was 25.59 mg/mL, 48 hours post treatment. The LC50 and LC90 in the AIT were 4.96 and 17.37 mg/mL and in TR were 0.04 and 1.24 mg/mL, respectively. It was possible to conclude that O. elegans had significant effect in engorged females and larvae repellency and may be in the future an adjuvant for tick control, prioritizing in vivo tests. In the second experiment, "Study of homeopathy in the control of natural infestation of R. (B.) microplus in dairy cattle... (Complete abstract click electronic access below)

Resumo: O objetivo dessa pesquisa foi realizar o screening fitoquímico, quantificar metabólitos secundários e determinar a atividade antioxidante do extrato bruto hidroalcoólico das folhas de Ipomoea batatas (L.) Lam. (batata-doce) (EBHBD). Foi determinada também sua toxicidade, atividade antimicrobiana e anti-inflamatória. Uma formulação farmacêutica em gel contendo o EBHBD foi desenvolvida para testar o seu efeito clínico no biofilme dental e gengivite em humanos. Os testes fitoquímicos foram realizados para determinar os componentes e quantificar os metabólitos secundários. A atividade antioxidante foi determinada pelo método do fosfomolibdênio. A análise toxicológica foi feita pelo teste de viabilidade celular e com o bioensaio utilizando Artemia salina (microcrustáceo). A análise microbiológica foi realizada por meio da sensibilidade em microrganismos aeróbios. A atividade anti-inflamatória foi avaliada em cultura de fibroblastos e com os testes de edema de orelha (camundongo) e pata (rato). A formulação em gel foi desenvolvida com EBHBD em hidroxietilicelulose, sendo conduzidos os testes de controle de qualidade (pH, densidade absoluta, consistência e avaliação microbiológica). O efeito do gel contendo EBHBD no biofilme dental e gengivite foi estudado utilizando um modelo de gengivite experimental parcial em humanos. Vinte e cinco indivíduos foram selecionados para participar deste estudo cruzado duplo-cego, no qual foram estabelecidos três períodos experimentais de 15 dias cada um com intervalo de 10 dias. Os pacientes foram submetidos a 3 tratamentos (T): T1- Gel placebo, T2- Gel contendo EBHBD a 10%; T3- Gel de clorexidina a 2% (controle positivo). Os parâmetros avaliados foram: índice de placa; índice de sangramento marginal modificado; fluido gengival e análise microbiológica do biofilme supragengival. Os dentes analisados foram: 15, 16, 35 e 36. Os resultados do estudo fitoquímico demonstraram a presença de flavonóides, alcalóides, antraquinonas, taninos e saponinas. A quantificação de metabólicos secundários mostrou em 100 g de material vegetal seco: fenólicos totais: 662,02 ± 28,91 mg; alcalóides: 345,65 ± 15,52 mg e antraquinonas: 328,44 ± 8,17 mg. A média da atividade antioxidante relativa do EBHBD foi igual a 43% e do gel foi 57%, em relação a 100% do total de atividade antioxidante atribuída ao ácido ascórbico. O EBHBD foi considerado atóxico e sem atividade antimicrobiana de acordo com os testes realizados. Foi observada redução na liberação de citocinas pró-inflamatórias em cultura de fibroblastos gengivais de humano (p<0,05) e diminuição da atividade anti-inflamatória no edema de orelha em camundongos (redução de 27%) e no edema de pata em ratos (redução de 24%). No estudo clínico não se observaram diferenças estatísticas (p>0,05) entre os parâmetros avaliados (índice de placa, sangramento marginal, fluído gengival e contagem de unidades formadoras de colônias de biofilme supragengival). Dentro das limitações deste estudo, sugere-se que o EBHBD apresentou moderada atividade antioxidante e propriedades anti-inflamatórias in vitro, porém não apresentou efeito clínico sobre biofilme dental e inflamação gengival
Abstract: The aim of this research was to perform the phytochemical screening, secondary metabolites quantification and determine the antioxidant activity of crude extract of the leaves of Ipomoea batatas (L.) Lam. (sweet potato) (EBHBD). The crude toxicity, antimicrobial activity and anti-inflammatory properties were also determined. A gel pharmaceutical formulation containing EBHBD was developed and evaluated the clinical effect on dental biofilm and gingivitis in humans. Phytochemical tests were conducted to determine the components and quantify secondary metabolites. The antioxidant activity was determined by the phosphomolybdenum method. Toxicological bioassays were carried out on brine shrimp (Artemia salina) and cell viability test. The Antimicrobial activity was performed on aerobic microorganisms. The anti-inflammatory activity was assessed in fibroblast cell culture and on the ear (mouse) and paw (rats) edema tests. The EBHBD hidroxietilicelulose gel formulation was developed and control quality tests were conducted (pH, absolute density, consistence and microbiological analysis). The effect of EBHBD gel on plaque and gingivitis was studied using an experimental model of partial gingivitis in humans. Twenty-five individuals were selected to participate in this double-blind crossover study, with three experimental periods of 15 days each with an interval of 10 days. The patients underwent three treatments (T): T1- Placebo gel, T2- 10% EBHBD gel T3- 2% chlorhexidine gel (positive control). The parameters evaluated were: plaque index, modified marginal bleeding index, gingival fluid and microbiological analysis of supragingival biofilm. Teeth evaluated: 15, 16, 35 and 36. The results demonstrated the presence of flavonoids, alkaloids, anthraquinones, tannins and saponins. The secondary metabolites quantification showed in 100 g of dried plant material: phenolic: 662.02 ± 28.91 mg; alkaloids: 345.65 ± 15.52 mg and anthraquinones: 328.44 ± 8.17 mg. The EBHBD antioxidant activity relative average was 43% and the 10% EBHBD gel was 57% in comparison of the ascorbic acid antioxidant activity (100%). The EBHBD was considered no toxic and no antimicrobial activity according to tests. The EBHBD reduced the release of pro-inflammatory cytokines on human gingival fibroblast cell culture (p <0.05) and decreased anti-inflammatory activity on ear edema in mouse (27% reduction) and paw edema in rats (24% reduction). In the clinical study there were no statisticaldifferences (p> 0.05) among the parameters (plaque index, marginal gingival bleeding, gingival fluid and colony-forming unit of supragingival biofilm). Within the limits of this study, it was possible suggest that the EBHBD showed moderate antioxidant and antiinflammatory properties in vitro, but showed no clinical effect on plaque and gingivitis

CoordenaÃÃo de AperfeiÃoamento de Pessoal de NÃvel SuperiorA Alpinia zerumbet à uma planta da famÃlia Zingiberaceae, denominada popularmente âcolÃniaâ no Nordeste do Brasil. à utilizada com fins medicinais no tratamento de hipertensÃo e tem sido estudada em relaÃÃo as suas propriedades farmacolÃgicas. Esta pesquisa teve por objetivo analisar o efeito farmacolÃgico das fraÃÃes hexÃnica (FHOEAz), clorofÃrmica (FCOEAz) e metanÃlica (FMOEAz) do Ãleo essencial da Alpinia zerumbet (OEAz) na reatividade vascular in vitro e nos parÃmetros cardiovasculares in vivo. O projeto de pesquisa foi aprovado pela ComissÃo de Ãtica em Pesquisa Animal, da Universidade Federal do CearÃ, sob os protocolos n 55/10 e n 18/2011, de acordo com as normas de boas prÃticas que envolvem o uso de animais experimentais. Para todos os experimentos foram utilizados ratos Wistar machos. Realizaram-se experimentos de reatividade vascular no banho de ÃrgÃos, com preparaÃÃes de aorta isolada de rato, com endotÃlio Ãntegro e desnudo, mantidos em carbogÃnio e soluÃÃo de Krebs-Henseleit com concentraÃÃo em mmol/L: NaCl: 118,0; KCl: 4,7; KH2PO4: 1,2; MgSO4.7H2O; 1,2; NaHCO3: 15,0; CaCl2: 2,5 e Glicose: 5,5. Foi observada a variaÃÃo da tensÃo isomÃtrica e utilizados diferentes fÃrmacos inibidores especÃficos para anÃlise do mecanismo de aÃÃo do efeito vasodilatador. Analisou-se a pressÃo arterial indireta por pletismografia de cauda em ratos submetidos ao modelo de hipertensÃo por inibiÃÃo crÃnica do Ãxido nÃtrico, atravÃs da administraÃÃo do L-NAME, obtendo-se a pressÃo arterial sistÃlica, diastÃlica e mÃdia, frequÃncia cardÃaca, alÃm da variaÃÃo do peso corporal. Constatou-se que o OEAz, FHOEAz, FCOEAz e FMOEAz induzem relaxamento de anÃis aÃrticos prÃ-contraÃdos com Fenilefrina (1 mol/L), de forma dependente da dose, sendo a menor CE50 a da FMOEAz (150,45 g/mL). A administraÃÃo por gavagem de 100 mg/kg de OEAz, FHOEAz, FCOEAz e FMOEAz reduziu a pressÃo arterial em ratos hipertensos pelo modelo de inibiÃÃo crÃnica do Ãxido nÃtrico, um efeito que foi superior ao controle negativo com Ãgua destilada e inferior aos controles positivos com Captopril e Nifedipina. A FMOEAz (0,1 - 3000 g/mL) induz relaxamento dependente da dose em anÃis aÃrticos prÃ-contraÃdos com Fenilefrina (1 mol/L) ou KCl (80 mmol/L), com endotÃlio intacto ou desnudo. Os estudos de mobilizaÃÃo de cÃlcio mostraram que a FMOEAz inibe o influxo de Ca2+ do meio extracelular, bem como interfere na contraÃÃo induzida pela liberaÃÃo de Ca2+ dos estoques intracelulares pela Fenilefrina (1 mol/L) ou CafeÃna (30 mmol/L). A 4-aminopiridina (1 mmol/L) e a Iberiotoxina (30 nmol/L) aumentam a CE50 da FMOEAz, mas nÃo interferem no seu efeito vasodilatador final. A prÃ-incubaÃÃo com L-NAME (100 mol/L), ODQ (10 mol/L); Indometacina (10 mol/L), Atropina (1 mol/L), Catalase (500 U/ml), SOD (300 U/mL); Wortmannina (0,5 mol/L), TetraetilamÃnio (10 mmol/L), Apamina (1 mol/L); Caribdotoxina (15 nmol/L) e Glibenclamida (10 mol/L) nÃo interferiram no relaxamento induzido pela FMOEAz. Concluiu-se que o OEAz, FHOEAz, FCOEAz e FMOEAz possuem efeito hipotensor in vivo e vasodilatador in vitro, e que o mecanismo de aÃÃo da FMOEAz, provavelmente, envolve o antagonismo aos canais de cÃlcio dependentes de voltagem, aos canais de cÃlcio operados por receptor, interferindo tambÃm na liberaÃÃo de cÃlcio dos estoques intracelulares.
The Alpinia zerumbet is a plant of the family Zingiberaceae, popularly called "colÃnia" in Northeastern Brazil. It is used for medicinal purposes to treat hypertension and has been studied in relation to its pharmacological properties. This study aimed to analyze the pharmacological effect of hexanic (HFEOAz), chloroformic (CFEOAz), and methanolic (MFEOAz) fractions of the essential oil of Alpinia zerumbet (EOAz) in the vascular reactivity in vitro and cardiovascular parameters in vivo. The research project was approved by the Ethics Committee on Animal Research, of the Federal University of CearÃ, under protocol numbers 55/10 and 18/2011, according to the standards of good laboratory practice involving the use of experimental animals. For all experiments male Wistar rats were used. Experiments of vascular reactivity were conducted in organ bath, with preparations of isolated rat aorta with intact endothelium and desnuded, kept in carbogen and Krebs-Henseleit solution with a concentration in mmol/L: NaCl: 118,0; KCl: 4,7; KH2PO4: 1,2; MgSO4.7H2O; 1,2; NaHCO3: 15,0; CaCl2: 2,5 e Glicose: 5,5. Was observed variation in isometric tension and used different specific inhibitors to analyze the mechanism of action of the vasodilator effect. We analyzed blood pressure indirectly by tail plethysmography in rats submitted to chronic hypertension by inhibition of nitric oxide by the administration of L-NAME, obtaining the systolic, diastolic and mean blood pressure, heart rate, beyond variation in body weight. It was found that the EOAz, HFEOAz, CFEOAz MFEOAz induced relaxation of aortic rings pre-contracted with Phenylephrine (1 mol/L), of dose-dependent manner, with the smallest of the EC50 MFEOAz (150.45 mg/mL). The administration by gavage of 100 mg/kg EOAz, HFEOAz, CFEOAz MFEOAz reduced blood pressure in hypertensive rats by the model of chronic inhibition of nitric oxide, an effect that was greater than the negative control with distilled water and less than the positive controls with Captopril and Nifedipine. The MFEOAz (0.1 - 3000 Âg/mL) concentration dependently relaxed Phenylephrine (1 mol/L) and KCl (80 mmol/L) contracted rings with intact or denuded endothelium. Studies of calcium mobilization showed that FMOEAz inhibits the influx of Ca2+ from the extracellular environment and interferes with the contraction-induced Ca2+ release from intracellular stocks by Phenylephrine (1 mol/L) or Caffeine (30 mmol/L). The 4-aminopyridine (1 mmol/L) and Iberiotoxina (30 nmol/L) increased the EC50 of MFEOAz but do not interfere in its final vasodilator effect. The pre-incubation with L-NAME (100 mol/L), ODQ (10 mol/L), Indomethacin (10 mol/L), Atropine (1 mol/L), Catalase (500 U/mL), SOD (300 U/mL), Wortmannin (0.5 mol/L), Tetraethylammonium (10 mmol/L), Apamin (1 mol/L); Caribdotoxin (15 nmol/L) and Glibenclamide (10 mol/L) did not interfere with the relaxation induced by MFEOAz. It was concluded that the EOAz, HFEOAz, CFEOAz and MFEOAz have hypotensive effect in vivo and vasodilator effect in vitro, and that the mechanism of action of MFEOAz probably involves the antagonism of calcium channels voltage-dependent, the calcium channel operated by receptor, also interfering in the release of calcium from intracellular stores.

O presente estudo teve como objetivo avaliar e comparar, morfologicamente, a resposta do tecido subcutâneo de ratos frente ao de hidróxido de cálcio associado a diferentes substâncias, sendo elas: clorexidina 0,2% em propilenoglicol, clorexidina 0,4% em propilenoglicol, Casearia sylvestris Sw (Guaçatonga) em propilenoglicol e propilenoglicol (que serviu como grupo controle). Para isso, foram utilizados 72 ratos Wistar. As pastas foram preparadas e colocadas em tubos de polietileno, que foram implantados no tecido subcutâneo do dorso de cada animal. Os períodos experimentais foram de 7, 14 e 30 dias após o procedimento cirúrgico, quando então, os animais foram mortos. As amostras coletadas passaram por processamento histotécnico e foram feitos cortes de 5µm de espessura e coloração com Hematoxilina e Eosina (H.E.). A avaliação das respostas do tecido conjuntivo em contato com as pastas testadas foirealizada de forma descritiva e quantitativa subjetiva.Os dados obtidos após análise quantitativa foram submetidos ao teste estatístico de Kruskal-Wallis e Dunn com nível de significância p<0,05. Os resultados mostraram que a clorexidina 0,4%, de modo geral, se mostrou mais irritante que os demais grupos. O extrato de Casearia sylvestris Sw apresentou comportamento satisfatório em relação à intensidade da reação inflamatória, igualando-se aos grupos 1 e 4. Com base na metodologia aplicada, foi possível concluir que aos 30 dias todos os grupos mostraram não interferir no processo de reparo e que todas as substâncias experimentais (clorexidina a 0,4%, a 0,2% e o extrato de Casearia sylvestris Sw) podem ser associadas ao hidróxido de cálcio.This study aimed to evaluate the response of rat subcutaneous tissue against calcium hydroxide associated with different substances: chlorhexidine 0.2% in propylene glycol, 0,4% chlorhexidine in propylene glycol, Casearia sylvestris (guaçatonga) in propylene glycol and propylene glycol (control group). The pastes were prepared and placed in polyethylene tubes, which were implanted in the dorsum of each animal (N=18). The experimental periods were 7, 14 and 30 days after surgery, at which time the animals were killed. The samples were histologically processed and stained with hematoxylin and eosin. The evaluation of the responses of connective tissue in contact with the pastes was performed using descriptive and quantitative analyses. The data obtained after the quantitative analysis were subjected to statistical test of Kruskal-Wallis and Dunn with significance level p <0.05. In overall, chlorhexidine 0,4%/calcium hydroxide showed the more intense inflamatory reaction in comparison to the other groups. The extract of Casearia sylvestris showed satisfactory performance in relation to the intensity of the inflammatory reaction, similar to groups 1 and 4. Based on the methodology, it was concluded that at 30 days all the materials do not to interfere with the repair process and that all experimental substances (chlorhexidine 0.4%, 0.2% and the extract of Casearia sylvestris) can be associated with calcium hydroxide.

Platonia insignis Mart. é uma espécie pertencente à família Clusiaceae, é popularmente conhecida como Bacuri e muito conhecida por ter um fruto de sabor apreciado. A utilização etnobotanica está relacionada à utilização do extrato do óleo de suas sementes como cicatrizante e anti-inflamatório e na produção de sabão. Atualmente diversas atividades vêm sendo relatadas para todas as partes deste fruto (semente, casca e polpa). Este trabalho teve como objetivo analisar o perfil fitoquímico, atividade antimicrobiana do extrato das folhas de Platonia insignis Mart. e desenvolver formulações farmacêuticas com ação antimicrobiana. A análise fitoquímica do extrato mostrou a presença de fenóis (taninos condensados, catequinas e flavonoides), esteroides, alcaloides e saponinas. As análises por LC-MSn forneceram os perfis de fragmentação dos compostos presentes no extrato. Na fração acetato de etila, foi identificado a fukugentina (morelloflavona) um importante marcador da família Clusiaceae. O extrato apresentou potencial antioxidante com inibição de 88,06% do radical DPPH. O sabonete, o creme e a solução tópica manipulados a partir do extrato a 1 e a 5% tiveram sua estabilidade analisadas no tempo zero e trinta dias após formulados, além da avaliação do controle de qualidade microbiológico. A avaliação da atividade antimicrobiana foi realizada pela técnica de microdiluição em caldo; o extrato hidroetanolico (70%), as frações hexânica, acetato de etila e os produtos manipulados apresentaram atividade antimicrobiana com CIM entre 0,78 e 12,5 mg/mL frente a todos os microrganismos testados exceto as frações orgânicas (acetato de etila e hexânica) que não apresentaram atividade frente Acinetobacter baumannii. A toxicidade avaliada pela técnica de hemólise não demonstrou atividade hemolítica até concentração testada de 100mg/mL. A toxicidade frente Artemia salina demonstrou que o extrato apresentou DL50 de 42,6 μg/mL sendo classificado como altamente tóxico frente Artemia salina. O extrato possui atividade antioxidante, microbicida e baixa toxicidade in vitro. As formulações farmacêuticas mostraram-se potencialmente viáveis no desenvolvimento de novos produtos para o tratamento de doenças infeciosas.Platonia insignis Mart. is a species belonging to Clusiaceae, is popularly known as Bacuri and is well-known for having a fruit of appreciated flavor. The ethnopharmacological use is related to the use of the oil of its seeds in the healing of scars and as an anti-inflammatory and in the production of soap. Currently, several activities have been reported for all parts of this fruit (seed, bark and pulp). This work aimed to analyze the phytochemical profile, biological, and antimicrobial activity of the leaf extract of Platonia insignis Mart., and develop pharmaceutical formulations. Phytochemical analysis of the extract showed the presence of phenols, condensed tannins, catechins, steroids, alkaloids, flavonoids and saponins. Analyzes by LC-MS and FIA-ESI-IT/MSn provided the fragmentation profiles of the compounds present in the extract and their structures were proposed. In the ethyl acetate fraction, fukugentin (morelloflavone) was identified as an important marker of the clusiaceae family. The extract presented antioxidant potential in the inhibition of 88,06% of the DPPH radical. The soap and the topical solution manipulated from the 1 and 5% extract had their stability analyzed at time zero and thirty days after formulations, besides the evaluation of the microbiological quality control. The antimicrobial activity was evaluated by the microdilution technique. The hydroethanolic extract (70%), the hexane, ethyl acetate and the manipulated products presented antimicrobial activity with MIC between 0.78 and 12.5 mg/mL to all the microorganisms tested except the organic fractions (ethyl acetate and hexane) that showed no activity against Acinetobacter baumannii. The toxicity evaluated by the hemolysis technique did not demonstrate hemolytic activity up to a concentration of 100 mg/mL. Toxicity to Artemia salina showed that the extract had LD50 of 42.6 μg/mL being classified as highly toxic against Artemia salina. The extract has antioxidant activity, microbicide and low in vitro toxicity. Pharmaceutical formulations have proved potentially viable in the development of novel products for the treatment of infectious diseases.

Himatanthus drasticus (Mart.) Plumel é uma espécie arbórea que pode chegar a sete metros de altura. Mais conhecida como janaguba é encontrada em áreas de cerrado, caatinga, campos rupestres e floresta tropical. Os usuários afirmam que a planta serve para o tratamento de tumores, hemorroidas, infecções do trato respiratório, aparelho digestivo e trato urogenital. Também relatam ação analgésica e antialérgica. Considerando as poucas publicações científicas sobre os efeitos farmacológicos da janaguba, o presente estudo avaliou os efeitos biológicos do látex em vários modelos experimentais. O látex dissolvido em água e liofilizado foi submetido à cromatografia em camada delgada, para a determinação das classes de metabólitos secundários, e empregado diretamente em ensaios de toxicidade aguda por gavagem (diretriz 425 da Organização para a Cooperação e Desenvolvimento Econômico), citotoxicidade (sarcoma 180 e carcinoma de Erlich), tripanocida (frente à cultura de epimastigotas de Trypanosoma cruzi), antibacteriano (microdiluição em caldo), antioxidante (método 2,2-difenil-1-picrilhidrazil), atividade antioxidante total e dosagem de fenóis, atividade genotóxica (ensaio cometa) e mutagênica (teste do micronúcleo). A cromatografia revelou a presença das seguintes classes: esteroides, saponinas, monoterpenos, sesquiterpenos, triterpenos, além de e açúcares redutores. Não houve efeito tóxico e citotóxico nem dano histopatológico (fígado, baço, coração, rim, pulmão). O látex não teve ação tripanocida. O método de microdiluição em caldo revelou um efeito inibitório nas concentrações de 3,13 e 1,56 para Acinetobacter baumannii ATCC 19606 e Escherichia coli ATCC 25922 respectivamente. O látex não teve atividade antioxidante significativa possivelmente devido ao valor reduzido dos compostos fenólicos (24,52 ± 0,21 µg EAG/mg). O teste de micronúcleo mostrou que o látex da janaguba não é mutagênico, mas pelo teste de cometa é considerado genotóxico. Esses resultados sugerem que o látex de H. drasticus possui segurança para uso agudo e potencial farmacológico antibacteriano.
Himatanthus drasticus (Mart.) Plumel is an arboreal species which can reach seven meters tall. More commonly known as janaguba is encountered in areas of cerrado, caatinga, rock fields and rainforest. The users claim that the plant serves for the treatment of tumors, hemorrhoids, respiratory tract infection, digestive and urogenital tract. They also report analgesic and antiallergic action. Considering the few scientific publications on the pharmacological effects of janaguba, the present study evaluated the biological effects of latex in various experimental models. The latex dissolved in water and lyophilized was subjected to thin layer chromatography, for the determination of classes of secondary metabolites, and directly employed in acute toxicity tests by gavage (guideline 425 of the Organization for Economic Cooperation and Development), cytotoxicity (sarcoma 180 and Ehrlich carcinoma), trypanocidal (front culture Trypanosoma cruzi), antibacterial (microdilution), antioxidant (using 2,2-diphenyl-1-picrylhydrazyl), total antioxidant activity and dosing phenols, genotoxic activity (comet assay) and mutagenic (micronucleus test). The chromatography revealed the presence of the following classes: steroids, saponins, monoterpenes, sesquiterpenes, triterpenes, and addition of reducing sugars. There was no toxic or cytotoxic effect and histopathologic injury (liver, spleen, heart, kidney, and lung). The latex had no trypanocidal action. The microdilution broth method has revealed an inhibitory effect at concentrations of 3.13 and 1.56 for Acinetobacter baumannii ATCC 19606 and Escherichia coli ATCC 25922 respectively. The latex had no significant antioxidant activity possibly due to the reduced amount of phenolic compounds (24.52 ± 0.21 ug EAG / mg). The micronucleus test showed that the latex janaguba is not mutagenic, but the comet test is considered genotoxic. These results suggest that the latex H. drasticus has security for acute use and antibacterial pharmacological potential.
