Canine distemper is a systemic viral disease characterized by immunosuppression followed by secondary infections. Apoptosis is observed in several immunosuppressive diseases and its occurrence on canine distemper in vivo has not been published. In this study, the occurrence of apoptosis was determined in lymphoid tissues of thirteen naturally infected dogs and nine experimentally inoculated puppies. Healthy dogs were used as negative controls. Samples of lymph nodes, thymus, spleen and brain were collected for histopathological purposes. Sections, 5 microm thick, of retropharingeal lymph nodes were stained by HE, Shorr, Methyl Green-Pyronin and TUNEL reaction. Shorr stained sections were further evaluated by morphometry. Canine distemper virus nucleoprotein was detected by immunohistochemistry. Retropharingeal lymph nodes of naturally and experimentally infected dogs had more apoptotic cells per field than controls. In addition, DNA from thymus of infected dogs were more fragmented than controls. Therefore, apoptosis is increased in lymphoid depletion induced by canine distemper virus and consequently play a role in the immunosuppression seen in this disease.

Treatment with HdCL reduced oxidative damage and modulated the expressions of CD4, CD8, FoxP3and HSP-60 in S180 solid tumor model, which can be associated to the presence of triterpenes, such as α-amyrin, β-amyrin and lupeol cinnamate. Present data emphasizes the importance of immune system in cancer and highlights the evaluation of the pharmacological properties of plants used by population as phytoterapics.

This study was developed at the Campus (C) and the Zoo-botanical Park (PZ) at the Federal University of Acre, with the purpose of identifying endoparasites in the avifauna of those locations. The birds were captured using 10 mist nets. The nets were set from 1 p.m. to 5 p.m.. The faecal samples collected were stored in Merthiolate, Iodine and Formaldehyde (MIF). Willies and direct methods were used for the diagnostic of endoparasites. Two hundred and eighty-seven birds were captured, with 34 recaptures, which resulted in 253 different specimens – 158 on the campus and 95 at the PZ. The birds caught were from 58 different species, belonging to 25 families and 12 orders. Fecal samples from 193 birds belonging to 49 species from 11 orders and 18 families were obtained and analyzed. The following endoparasites were identified: Eimeria sp., Entamoeba coli, Entamoeba histolytica, Iodamoeba bütschlii, Isospora sp., Enterobius vermicularis, Heterakis gallinarum, Ascaridia galli, Strongyloides avium, Capillaria spp., Ancylostoma spp., Raillietina sp., Choanotaenia sp., Microphallus sp., and Echinostoma revolutum. Eimeria sp. was the most frequent parasite found in most bird species. The results showed a high level of endoparasitic infection in the aviary community in the two study areas.

Devido ao desmatamento, a fragmentação fl orestal é uma realidade cada vez mais presente no oeste do estado do Acre. O estudo objetivou avaliar variações na riqueza e abundância de morcegos em um fragmento fl orestal urbano de aproximadamente 150ha localizado na cidade de Rio Branco (AC). As coletas foram realizadas em dois sítios: sendo dois pontos de coleta a 200m da borda e outros dois a 20m da borda. Redes de neblina fi caram abertas quatro horas depois do pôr-do-sol, durante três noites/mês. O índice de diversidade de Shannon-Wiener (H') e o índice de similaridade de Jaccard (J) foram usados para análise comparativa. Durante 48 noites (novembro/2005-julho/2007) foram capturados 85 morcegos de 15 espécies, com maior riqueza e abundância de quirópteros no interior do fragmento. A similaridade de espécies foi baixa (J=0,44), indicando preferência de habitat. O índice de diversidade encontrado (H'=2,091 nats/indiv) foi similar a de outros estudos na Amazônia, com menor diversidade na borda (H'=1,864) do que no interior do fragmento (H'=2,047). Carollia perspicillata (n=32) e Artibeus lituratus (n=13) responderam por 57,6% do total de capturas. As características da matriz e a adaptação dos morcegos às redes explicam os valores encontrados.

UNIPAR, Umuarama, v. 17, n. 3, p. 167-172, jul./set. 2014. RESUMO:A comercialização de alimentos em feiras livres, expostos em barracas sem refrigeração e sem proteção pode alterar a qualidade dos alimentos. Alimentos crus e mal conservados podem ser veículos de contaminação por microrganismos causadores de toxinfecção e, dessa forma, colocar em risco a saúde do consumidor. Objetivou-se neste trabalho avaliar e definir um diagnóstico de feiras livres realizadas em quatros municípios paraibanos, localizados na mesorregião do Agreste: Campina Grande, Esperança, Areia e Bananeiras. Utilizou-se como metodologia o estudo analítico, por meio de um roteiro de observação pré-confeccionado, baseado nas recomendações da Agência Nacional de Vigilância Sanitária. O roteiro de observação do tipo checklist foi dividido em quatro seções: aspectos físicos, aspectos higiênicos, aspectos ambientais e aspectos organizacionais. Os resultados foram bastante insatisfatórios, tendo em vista que nos quatro aspectos de avaliação todos os municípios apresentaram pouquíssima conformidade. Do ponto de vista de saúde pública, as condições higiênicas de comercialização de alimentos mostraram-se precárias, principalmente, porque um grande número de pessoas fazem uso deste tipo de comércio para a aquisição de alimentos nas regiões estudadas. Foi permitido concluir que se faz necessário a implantação de políticas sociais e educacionais direcionadas para as feiras livres no estado da Paraíba. PALAVRAS-CHAVE: Qualidade. Saúde Pública. Segurança Alimentar. EVALUATION AND DIAGNOSTIC OF FOOD SALE CONDITIONS IN STREET MARKETS IN THE STATE OF PARAIBA, BRAZILABSTRACT: The trading of food in street markets exposed in tents without refrigeration or protection can change its quality. Raw and poorly preserved foods can become vehicles of contamination by microorganisms causing poisoning, and thus jeopardizing the health of the consumers. The objective of this study is to evaluate and define a diagnosis of street markets held in four cities in Paraiba, located in the middle region of the Wasteland: Campina Grande, Esperança, Areia and Bananeiras. The analytic study was used as methodology, by means of a previously made observation script, based on the recommendations from the National Health Surveillance Agency. The observation checklist script was divided into four sections: physical aspects, hygiene aspects, environmental aspects and organizational aspects. The results were quite unsatisfactory considering that in the four evaluation aspects, all municipalities showed very little conformity. From a public health point of view, the hygienic conditions of food trading proved to be precarious, mainly because a large number of people make use of this type of commerce for purchasing food in the regions studied. Therefore, it can be concluded that it is necessary to implement social and educational policies dir...
