Abstract:
Lodgepole pine/Labrador tea (Pinus contorta Dougl. ex Loud. var. latifolia/Ledum groenlandicum Oeder) relevés were classified and characterized based on data from archival sources (n = 428). Eleven forest communities were recognized and were distinguished by the relative dominance of Sphagnum, Cladina and Cladonia, Lycopodium, Vaccinium species, or feathermosses. Picea mariana (Mill.) BSP was the common secondary successional species. Most paired-community comparisons were nonoverlapping in ordination space, although intermingling sometimes occurred along interfaces. Lodgepole pine/Labrador tea stands occurred on upland sites within the boreal–cordilleran ecoclimatic transition zone along the eastern slopes of the Rocky Mountains from southwestern Alberta to the southern Yukon Territory. Nine communities had mesic to subhygric moisture and submesotrophic to mesotrophic nutrient regimes. The exceptions were a Pinus contorta/Ledum groenlandicum/Sphagnum (wetter sites) and a Pinus contorta/Ledum groenlandicum/Cladina mitis (drier sites) community. An inverse correlation occurred between latitudinal location and elevation of occurrence (r = –0.56, P < 0.001, n = 403) with a northward decline of 65 m/100 km. The concept of a "type community" is proposed for formally documenting the composition of plant communities and optimizing the comparability of different types. Eight of the recognized communities fulfilled the proposed criteria for a type community and two were considered provisional types.Key words: vegetation classification, Pinus contorta, Ledum groenlandicum, type community.

Abstract:
Bad breath or halitosis is an oral condition caused by volatile sulfur compounds (VSC) produced by bacteria found in the dental and tongue biofilms. Fusobacterium nucleatum is a Gram-negative anaerobic bacterium that has been strongly associated with halitosis. In this study, essential oils (EO) from three plants, Labrador tea (Rhododendron groenlandicum [Oeder] Kron & Judd), peppermint (Mentha x piperita L.), and winter savory (Satureja montana L.), were investigated for their effects on growth, biofilm formation and killing, and VSC production by F. nucleatum. Moreover, their biocompatibility with oral keratinocytes was investigated. Using a broth microdilution assay, winter savory EO and to a lesser extent Labrador tea and peppermint EO showed antibacterial activity against F. nucleatum. A treatment of pre-formed biofilms of F. nucleatum with EO also significantly decreased bacterial viability as determined by a luminescence assay monitoring adenosine triphosphate production. The EO were found to permeabilize the bacterial cell membrane, suggesting that it represents the target of the tested EO. The three EO under investigation were able to dose-dependently reduce VSC production by F. nucleatum. Lastly, no significant loss of cell viability was observed when oral keratinocytes were treated with the EO at concentrations effective against F. nucleatum. This study supports the potential of Labrador tea, peppermint, and winter savory EO as promising agents to control halitosis and promote oral health.

Hébert, F. and Thiffault, N. 2011. The Biology of Canadian Weeds. 146. Rhododendron groenlandicum (Oeder) Kron and Judd. Can. J. Plant Sci. 91: 725–738. Rhododendron groenlandicum (Oeder) Kron and Judd, bog Labrador tea, is an evergreen shrub from the Ericacae family native to North America. Bog Labrador tea is associated with the later stages of forest successions in black spruce forest stands of the boreal ecosystems with cool climates, but responds aggressively to forest openings where it is already present. In general, bog Labrador tea is associated with nutrient-poor, acidic soils, with drainage ranging from moist to wet. Layering is the main regeneration strategy of the species; evidence suggests that this could be especially true following disturbances that open the forest canopy. Sexual reproduction maintains viability in undisturbed communities through wind or water dispersal. Rhododendron groenlandicum acclimates more rapidly relative to black spruce after perturbations through a higher rate of resource utilization when resources are available. The species is a highly competitive shrub for soil nutrients; it competes with regenerating conifers for soil nitrogen and phosphorus. It can also assimilate organic nitrogen from the soil through its mycorhizae. These characteristics may lead to the formation of ericaceous heaths that can stay unforested indefinitely. However, this species can be eradicated by herbicides (glyphosate) and heavy site scarification can limit its propagation.

Abstract:
The traditional medicinal plant, Labrador tea (Rhododendron groenlandicum(Oeder) Kron & Judd; Ericaceae), present in the pharmacopoeia of the Cree of Eeyou Istchee, has shown glitazone-like activity in the 3T3-L1 adipogenesis bioassay. This activity has been attributed to phenolic compounds, which have been shown to vary in this plant as a function of insolation parameters. The goal of this study was to determine if these changes in phenolic content were pharmacologically significant. Leaves were harvested in 2006 throughout the James Bay region of Northern Quebec and ethanol extracts were testedin vitrousing the 3T3-L1 murine cell line adipogenesis bioassay. This traditional medicinal plant was found active in the assay. However, there was no detectable spatial pattern in the accumulation of intracellular triglycerides, suggesting that such patterns previously observed in the phenolic profile of Labrador tea were not pharmacologically significant. Nonetheless, a reduction in the adipogenic activity was observed and associated with higher concentrations of quercetin for which selected environmental variables did not appropriately explain its variation.

Abstract:
Plant habitat, growth, fruit yield and occurrence of pollinators in cloudberry and lingonberry fields/bogs were monitored and analyzed at three locations in southern Labrador: Lanse’au Clair (51°41’ N, 57°08’ W), Red Bay (51°43’ N, 56°26’ W), and Cartwright (53°42’ N, 57°0’ W) over the two growing seasons, 2011 and 2012. The length of the growing seasons was 100–120 d ( DFRA 2014 ) with 600–700 growing degree days (GDD) ( AAFC 2014 ). The 2012 season was warmer than 2011. The plants recorded in belt transects belong to six families: Rosaceae, Ericaceae, Pottiaceae, Juncaeae, Equisetaceae, and Sphagnaceae. In the Ericaeae family, Vaccinium vitis-idaea, Arctostaphylos alpina, Empetrum nigrum, and Vaccinium angustifolium were found. In both seasons, the cloudberry was the first to bloom, followed by wild blueberry, lingonberry, and Labrador tea. The fruit yields of cloudberry and partridgeberry in southern Labrador were higher than those recorded in Finland, Norway, and in the USA. Pollinators were present in large numbers. Most of the specimens were from three orders: Hymenoptera, Diptera, and Lepidoptera. Temperature, precipitation, wind, and sunlight affected plant growth and the occurrence of pollinators. To our knowledge this is the most comprehensive study of plant growth, yield, and pollinators’ activity in cloudberry/partridgeberry fields conducted in Southern Labrador, Canada.

Abstract:
Surficial geochemical methods were applied to delineate zones of anomalous uranium and related element concentrations in areas overlain by an extensive blanket of glacial sediments and dense vegetation cover in the Jacque’s Lake area of the Central Mineral Belt, Labrador, Canada. The study involved sampling and analyses of vegetation including black spruce twigs and bark, Labrador tea shoots, and humus. Ash derived from the vegetation samples was analyzed using inductively coupled plasma – mass spectrometry (ICP–MS) following ignition at 450 °C, and humus was analyzed with delayed neutron counting (DNC) for a suite of 35 elements. B-horizon soil was analyzed using aqua regia digestion to investigate potential chemical signatures of bedrock mineralization at the surface. Uranium concentration in humus varied from 0.05 to 885 ppm. Zones exhibiting anomalous U responses were associated with areas proximal to anoxic peat and sphagnum bogs where mobile U species were sequestered. Uranium and pathfinder element (e.g., Pb, V, Sr, and Mo) concentrations were low in the <250 μm fraction of B-horizon soils. The soil geochemistry delineated bedrock U mineralization in areas with <15 cm of overburden and U concentration varied from 50 to 405 ppm. Biogeochemical signatures of the bedrock mineralization in black spruce twigs produced greater anomaly to background contrasts for U and pathfinder elements (e.g., Be, Ag, Pb, Ca, and Sb) and correlated more precisely with the detected radiometric U/Th anomaly than did those of soil and humus. Principal component analysis of spruce twig data discriminated three major components, including plant nutrients, ore-related elements, and a mobile species. Uranium concentration varied from below detection limit to 23 ppm U in black spruce bark and from below detection limit in ∼40% of samples to 18 ppm in Labrador tea stem.

Abstract:
This thesis examines the cytochrom P450 (CYP) drug metabolizing enzyme inhibition and antimicrobial properties of 46 common food plants available in the Canadian Market and the inhibitory properties of 17 traditional Cree antidiabetic medicines on aldose reductase. Inhibitory activity profiles of CYP 3A4, 3A5, 3A7 and 2D6 were created for the 46 samples. The most active plants in the CYP inhibition assay were the spices, belonging to the Apiaceae and Lamiaceae. Similarly, the most active plants in the antimicrobial assay were also the Apiaceae and Lamiaceae. Swine lens homogenate was tested as a novel model for the aldose reductase inhibition assay. Several Cree plants selected for the aldose reductase study showed a high activity, primarily in samples which also contained high levels of phenolics. A positive correlation was observed between total phenolics content and aldose reductase inhibition r2=0.44, p=0.05. Crude extracts of Rhododendron groenlandicum exhibited inhibitory activities of 35.11 ± 0.16 %. The subfractionation and HPLC analysis of R. groenlandicum revealed high levels of phenolics compounds including, catechin, epicatechin, quercetin and quercetin glycosides. This study found that medicinal and food plants contain phytochemicals that may have both beneficial and detrimental biological effects.
Nous avons étudié dans cette thèse les capacités de 46 plantes comestibles, disponibles sur le marché canadien, à inhiber le cytochrome P450 (CYP), enzyme responsable du métabolisme des médicaments, les propriétés antimicrobiennes, et les propriétés inhibitrices de l'aldose réductase à partir de 17 médicaments antidiabétiques traditionnellement utilisés par les Cris. Les profils de l'activité inhibitrice du CYP 3A4, 3A5, 3A7 et 2D6 ont été réalisés pour les 46 plantes à l'étude. Les plantes les plus actives dans le test d'inhibition du CYP furent les épices, plantes appartenant aux familles des Apiaceae et Lamiaceae. De même, les plantes les plus actives dans le bioessai antimicrobien furent aussi les plantes de ces deux mêmes familles. Un homogénat de cristallin de porc a été utilisé comme modèle nouveau pour le test d'inhibition de l'aldose réductase. Plusieurs plantes, utilisées par la nation Cri, qui ont été sélectionnées pour l'étude ont montré une forte activité inhibitrice de l’aldose réductase, principalement dans les échantillons qui contenaient des teneurs élevées en composés phénoliques. Une corrélation positive a été observée entre la teneur totale en composés phénoliques et l'inhibition de l'aldose réductase (r2 = 0.44, p = 0.05). Des extraits bruts de Rhododendron groenlandicum ont montré des activités inhibitrices de 35.11 ± 0.16%. Le sous-fractionnement et l'analyse HPLC de R. groenlandicum ont aussi révélé des teneurs élevées des composés phénoliques, incluant la catéchine, l'épicatéchine, la quercétine et les glycosides de quercétine. Cette étude a montré que les plantes médicinales et alimentaires contiennent des composés phytochimiques qui peuvent avoir à la fois des effets biologiques bénéfique et préjudiciable.

Abstract:
Le diabète est un syndrome métabolique caractérisé par une hyperglycémie chronique due à un défaut de sécrétion de l’insuline, de l’action de l’insuline (sensibilité), ou une combinaison des deux. Plus d'un million de canadiens vivent actuellement avec le diabète. La prévalence de cette maladie est au moins trois fois plus élevée chez les autochtones que dans la population canadienne en général. Notre équipe vise à étudier les effets potentiellement antidiabétiques de certaines plantes médicinales utilisées par les Cris d'Eeyou Istchee (Baie James, Québec) où l’adhérence aux traitements médicamenteux est faible, en partie à cause de la déconnection culturelle de ces derniers. Grâce à une approche ethnobotanique, notre équipe a identifié 17 plantes médicinales utilisées par cette population pour traiter des symptômes du diabète. Parmi ces plantes, l’extrait éthanolique de Rhododendron groenlandicum (Thé du Labrador) a montré un fort potentiel antidiabétique chez plusieurs lignées cellulaires, notamment les adipocytes (3T3-L1). Cette plante induit la différenciation adipocytaire probablement par l’activation du peroxisome proliferator-activated receptor gamma (PPAR γ). Cette stimulation améliore la résistance à l’insuline et constitue un mécanisme privilégié pour une classe de médicaments antidiabétiques, les thiazolidinediones. Le but de la présente étude est de valider l’efficacité et l’innocuité de R. groenlandicum in vivo, dans un modèle animal de résistance à l’insuline, d’élucider les mécanismes par lesquels cet extrait exerce ses effets antidiabétiques et d’identifier les principes actifs responsables de son activité. L'isolation et l'identification des constituants actifs ont été réalisées à l’aide d'une approche de fractionnement guidé par bioessai; en l'occurrence, l'adipogénèse. Cette approche, réalisée dans la lignée adipocytaire 3T3-L1, a pour but de mesurer leur teneur en triglycérides. Des études in vivo ont été réalisées sur le modèle de souris DIO (diet induced obesity). L'extrait éthanolique du R. groenlandicum a été incorporé à la nourriture grasse (35% d’apport calorique lipidique) à trois doses différentes (125, 250 et 500 mg / kg) sur une période de 8 semaines. Des tissus cibles de l’insuline (foie, muscle squelettique et tissus adipeux) ont été récoltés afin de faire des analyses d’immunobuvardage de type western. La quercétine, la catéchine et l’épicatéchine ont été identifiées comme étant les composés actifs responsables de l'effet antidiabétique du R. groenlandicum. Seules la catéchine et l’épicatéchine activent l’adipogénèse uniquement à forte concentration (125-150 M), tandis que la quercétine l’inhibe. L’étude in vivo a montré que le traitement avec R. groenlandicum chez les souris DIO réduit le gain de poids de 6%, diminue l'hyperglycémie de 13% et l’insulinémie plasmatique de 65% et prévient l’apparition des stéatoses hépatiques (diminution de 42% de triglycéride dans le foie) sans être toxique. Les analyses d’immunobuvardage ont montré que R. groenlandicum stimule la voie de l’insuline via la phosphorylation de l’Akt et a augmenté le contenu protéique en Glut 4 dans les muscles des souris traitées. Par contre, dans le foie, le R. groenlandicum passerait par deux voies différentes, soit la voie insulino-dépendante par l’activation de l’AKT, soit la voie insulino-indépendante par la stimulation de l’AMPK. L’amélioration observée des stéatoses hépatiques chez les souris DIO traitées, a été confirmée par une baisse du facteur de transcription, SREBP-1, impliqué dans la lipogénèse de novo, ainsi qu’une diminution de l’inflammation hépatique (diminution de l’activité d’IKK α/β). En conclusion, l’ensemble de ces résultats soutiennent le potentiel thérapeutique de Rhododendron groenlandicum et de ses composants actifs dans le traitement et la prévention du diabète de type 2. Nous avons validé l'innocuité et l'efficacité de cette plante issue de la médecine traditionnelle Cri, qui pourrait être un traitement alternatif du diabète de type 2 dans une population ayant une faible adhérence au traitement pharmacologique existant.
Diabetes is a metabolic syndrome characterized by chronic hyperglycemia due to a defect in insulin secretion, insulin action (sensitivity), or both. More than one million Canadians are currently living with diabetes. The prevalence of this disease is at least three times higher among indigenous people than in the general Canadian population. Our team studied the potential effects of certain anti-diabetic medicinal plants used by the Cree nation of Eeyou Istchee (James Bay, Quebec) where compliance to western treatment is low due in part to the cultured disconnect of the latter. Using an ethnobotanical approach, we identified 17 medicinal plants used by this population to treat symptoms of diabetes. Among these plants, the ethanol extract of Rhododendron groenlandicum (Labrador Tea) showed strong anti-diabetic potential in several cell lines, including adipocytes (3T3-L1) where it induced differentiation probably by stimulating the peroxisome proliferator-activated receptor gamma (PPAR γ). Such stimulation has been shown to improve insulin resistance, a mechanism used by a class of anti-diabetic drugs, the thiazolidinediones. The aim of the present study is to validate the effectiveness and the safety of R. groenlandicum in vivo in a mouse model of insulin resistance, to elucidate the mechanisms by which it exerts its effects and to identify the active principles responsible for its activity. Isolation and identification of active constituents of R. groenlandicum were performed using a fractionation approach guided by the increase of triglyceride content in the adipocyte (3T3-L1). In vivo studies were performed on a DIO (diet induced obesity) mouse model. The ethanolic extract of R. groenlandicum was incorporated into the high fat diet (35% energy derived from lipids) at three different doses (125, 250 and 500 mg / kg) over a period of 8 weeks. Western immunoblot analysis was performed on different tissues (liver, skeletal muscle, adipose tissue) collected at the end of the study. Quercetin, catechin and epicatechin were identified as the active compounds responsible for the anti-diabetic effect of R. groenlandicum. Alone, catechin and epicatechin activate adipogenesis only at high concentrations (125-150 M) while quercetin inhibits it. In vivo, treatment of DIO mice with R. groenlandicum diminished weight gain by 6 %, reduced blood glucose by 13%, insulin plasma by 65% and prevented hepatic steatosis (triglycerides levels decreased by 42%) without significant toxicity. Western blot analysis showed that R. groenlandicum increased Glut 4 protein content in skeletal muscle by activating the insulin dependent pathway implicating Akt. Effects of R. groenlandicum on hepatic steatosis seems to involve both pathways; the insulin dependent Akt and insulin independent AMPK pathways. This correlated with decreased SREBP-1 hepatic content, a transcription factor involved in de novo lipogenesis, and with a reduction of inflammation (decrease in the activity of IKK alpha / beta). Taken together, these results support the therapeutic potential of Rhododendron groenlandicum and its active compounds in the treatment and prevention of type 2 diabetes. We validated the safety and efficacy of this plant from traditional Cree medicine. It could represent an alternative treatment of type 2 diabetes in a population that has a poor compliance to pharmacological treatments.

Abstract:
Introdução: Em cães as neoplasias oculares têm sido relatadas com maior frequência em oftalmologia veterinária. As pálpebras são divididas em superior, inferior e membrana nictitante, e sua função principal é a proteção do bulbo ocular entre outras. Uma neoformação pode ocasionar deformações como consequência e até leões corneais. Assim, podem ser agressivos devido ao seu potencial metastático e comportamento biológico neoplásico. As neoplasias em conjuntiva melanociticas em cães, apesar de pouco comuns, quando diagnosticados podem ser maligno (melanoma) e benigno (melanocitoma), representando 81% e 19 % respectivamente. Algumas raças são mais acometidas como: Labrador Retriever, Golden Retriever, Rottweiler e Cocker Spaniel. O diagnóstico é através do exame oftalmológico completo e exames como o histopatológico, onde é avaliado atipia celular e índice mitótico como diagnóstico diferencial. O tratamento é estritamente cirúrgico, como a exérese. Neste contexto, este estudo tem como objetivo realizar uma revisão sobre os aspectos gerais e histopatológicos sobre melanoma na espécie canina. Materiais e Métodos: Tratou-se de uma pesquisa bibliográfica descritiva a fim de atender os objetivos propostos. Foram analisados leituras de periódicos, revistas, trabalhos e artigos eletrônicos indexados sobre o tema. Resultados: A partir da análise dos estudos, o melanoma tem maior incidência em cães com idade avançada, entre 8 e 10 anos, o local de predileção a superfície bulbar da terceira pálpebra. O melanocitoma pode apresentar em superfície palpebral, bulbar e terceira pálpebra. Dentre os sinais clínicos podem apresentar uveíte, endoftalmite por necrose tumoral e massa visível. Histopalogicamente, o melanoma da conjuntiva, apresentam-se como massas bastantes pigmentadas ou não, por melanócitos (melânicas ou amelânicas) , pendiculadas ou não e/ou ulceradas. Nestas células neoplásicas é possível observar elas infiltrando a derme e tecido subcutâneo, são fusiformes / redondas. Contudo os melanomas malignos podem ter alto índice mitótico, mas já relatado em literatura podem ser amelânicos com baixa atividade mitótica, porém quando malignos podem se apresentar alto poder infiltrativo e invasivo. Conclusão: Tendo em vista a correlação direta entre o potencial metastático e índice mitótico sendo melânico ou amelânico, o uso do histopatológico tem sido uma ferramenta essencial definição do tratamento e sobrevida do paciente.

Abstract:
Introdução: A paralisia de laringe é caracterizada como uma condição na qual os músculos responsáveis pelo movimento de abdução e adução das cartilagens aritenóides se apresentam enfraquecidos. A paralisia de laringe pode ocorrer em qualquer raça ou idade, porem a maioria dos cães que desenvolvem a patologia geralmente são geriátricos de raças grandes ou braquicefálicos. Objetivo: Prover uma referência para médicos veterinários sobre a temática da paralisia de laringe. Materiais e métodos: Formar um compilado de informações obtidas através da análise de artigos e literaturas. Resultados: A paralisia de laringe pode ter origem idiopática, traumática, neoplásica, por doenças degenerativas dos nervos e músculos da laringe e de forma congênita, normalmente associada a cães das raças Husky Siberiano, Bull Terrier, Bouvier de Flandres, Dálmatas, Great Pirennes, Rottweillers Golden e Labrador Retriever. Os sinais clínicos são muitas vezes inespecíficos evidenciados por dificuldade respiratória, ruído estridor, disfonia, tosse, desmaio, cianose, dor, edema e inquietação, e geralmente ocorre durante a realização de esforços físicos em dias quentes e úmidos. Devido a obstrução da via respiratória o animal deve ser encaminhado o mais rápido possível para o atendimento de emergência. O principal exame diagnostico é realizado através de laringoscopia direta, entretanto caso necessário o medico veterinário pode solicitar exames laboratoriais, radiografia, ultrassonografia e fluoroscopia. O tratamento primário consiste em fornecimento de oxigênio, controle de temperatura, podendo ser necessário a realização de traqueostomia no paciente, enquanto que o tratamento definitivo consiste procedimentos cirúrgicos para reposicionamento e fixação das aritenóides. A prevenção consiste em evitar traumas e lesões na região da laringe decorrentes do uso de coleira/enforcador, brigas e quedas. O prognostico pode variar de favorável a reservado, dependendo da etiologia. Conclusão: A paralisia de laringe é uma doença que provoca obstrução da via aérea podendo levar a óbito. Sendo assim, um conhecimento adequado se torna fundamental para possibilitar o tratamento e melhora do animal.

Abstract:
Introdução: As afecções oncológicas possuem grande incidência na clínica médica dos animais de companhia. Em cães, um dos tumores malignos mais diagnosticados é o mastocitoma, que representa 20% dos casos. Trata-se de uma patologia multifatorial, que ocorre em animais de qualquer faixa etária, mas principalmente em adultos com idade média de oito a nove anos. Cães braquicefálicos são mais acometidos, entretanto pode-se observar a doença em outras raças como Boxer, Golden Retriever e Labrador. Objetivos: Diante do aumento no número de pacientes oncológicos na clínica veterinária, o presente trabalho tem por objetivo realizar uma revisão de literatura em busca da compreensão sobre o mastocitoma, sua patogenia, diagnóstico e tratamento. Material e métodos: Para isso, foi realizada uma pesquisa bibliográfica a partir das plataformas – Google acadêmico, SciELO e Pubvet; entre o período de 2013 a 2021. Resultados: A forma cutânea do mastocitoma é a mais apresentada pelos pacientes, principalmente em derme e tecido subcutâneo. Pode se manifestar em um único nódulo de comportamento benigno, assim como em múltiplos nódulos metastáticos, afetando principalmente membros posteriores. A nodulação pode ser granulomatosa ou ulcerativa, possuindo ou não aspecto avermelhado e prurido. Sua classificação é de baixo a alto grau de malignidade e o tratamento se baseia de acordo com a classificação histopatológica e o estadiamento da doença. A causa do mastocitoma é desconhecida, todavia, sabe-se que o receptor tirosina-quinase c-KIT está envolvido. O diagnóstico é realizado a partir dos exames citológico e histopatológico, sendo este último indicado para classificar o grau de malignidade. A punção aspirativa por agulha fina é o método de escolha para o exame. A excisão cirúrgica é o tratamento mais efetivo, desde que realizado com margens de segurança. A quimioterapia pode ser realizada de forma conjunta para cito-redução ou como adjuvante em casos de mastocitomas de grau II ou III, que também podem exigir tratamento medicamentoso onde se emprega o uso de vimblastina, prednisona, ciclofosfamida e lomustina. Radioterapia e terapias complementares também podem ser empregadas. Conclusão: Portanto, é fundamental que seja realizada uma avaliação dos fatores prognósticos para que a conduta terapêutica adequada seja estabelecida para o paciente.

Abstract:
Introdução: O baço é considerado o maior órgão do sistema linfático dos cães e alvo de múltiplas enfermidades por conta de sua localização anatômica e funcional. Apesar de realizar diversas funções importantes no organismo, com destaque na atividade linfática, imunológica, circulatória e hematopoiética, é possível viver sem o mesmo. A esplenomegalia consiste no aumento do baço, enquanto o termo esplenomegalia localizada é o aumento focal do baço, podendo ser ou não de origem patológica. Normalmente, doenças esplênicas possuem sinais clínicos inespecíficos, como diarreia, vômito, anorexia e perda de peso, sendo a esplenomegalia o sinal clínico mais específico. Objetivo: Esta revisão tem como objetivo avaliar as principais afecções que ocasionam a esplenomegalia localizada. Material e métodos: Revisão bibliográfica realizada em julho de 2021, baseada nos dados do PUBVET; Scielo; Repositórios da Unesp; USP; Journal of Veterinary Internal Medicine e no livro Oncologia em Cães e Gatos. Resultados: Alguns autores indicam que 48% das esplenomegalias podem ser de origem neoplásica e 51% de origem não neoplásica, obtendo como principais causas do último grupo, a hiperplasia nodular, hematoma, abscesso e enfarte. A neoplasia primária é uma das principais causas da esplenomegalia localizada, tendo em vista que o hemangiossarcoma é responsável por 80% dos casos nos cães e considerado um dos sarcomas com maior potencial metastático e pior prognóstico. O hemangiossarcoma é um tumor originado de células endoteliais, considerado maligno e pode ser localizado em qualquer tecido corporal, todavia, 50% são encontrados no baço, afetando principalmente raças de grande porte como Golden Retriever, Pastor alemão e Labradores, com maior incidência em machos com idade de 8 a 13 anos. O diagnóstico é realizado por ultrassom ou radiografia, portanto, o diagnóstico definitivo é a biopsia incisional ou excisional do tumor. O diagnóstico prévio é importante por sua alta taxa de mortalidade. Conclusão: Ainda que nem sempre seja de origem patológica, a esplenomegalia localizada é um sinal clínico importante a ser observado, podendo ser ocasionada principalmente por neoplasias primárias como o hemangiossarcoma, tendo em consideração a importância de seu diagnóstico precoce a fim de evitar complicações.
