Serum chemistry analyses represents a fundamental tool for the diagnosis and understanding of diseases in marine mammals. Although several studies are being conducted within the field of clinical pathology, haematological and serum chemistry data for Antillean manatees are deficient. The purpose of this study was to determine serum chemistry values for captive Antillean manatees within the CMA/Ibama facility in Brazil. Serum samples were obtained from five captive adult Antillean manatees fed with seagrass and analysed for aspartate aminotransferase, alanine aminotransferase, bilirubin, alkaline phosphatase, urea, creatinine, glucose, triglycerides, cholesterol, total protein, albumin, globulin, phosphate, chloride, calcium and uric acid. Blood chemistry parameters were determined using a semi-automatic analyzer. Maximum, minimum, mean and standard deviations were calculated for each serum chemistry parameter. Differences on the values of males and females were verified using an unpaired Student's t-test. All the parameters analysed were similar between sexes, with exception of AP, which was higher in females (191.43 +/- 31.86 U/l). Alanine aminotransferase and uric acid values for Trichechus manatus manatus are reported for the first time in this paper. This study is the first to report serum chemistry parameter values for long-term captive male and female Antillean manatees. Therefore, the lower values of albumin, phosphate, chloride, cholesterol and triglycerides obtained here highlight the importance of clinical pathology during health monitoring of captive marine mammals.
RESUMOAvaliaram-se dois protocolos para a produção de plasma rico em plaquetas (PRP) com o sangue de 20 cães adultos. Foram coletados três frascos de sangue em que um deles foi usado para produção do PRP por meio do protocolo A − centrifugação única a 1200rpm/10min −, o outro para fabricação do PRP pelo protocolo B − primeira centrifugação a 1200rpm/10min e a segunda centrifugação a 1600rpm/10min − e o terceiro para realização da contagem plaquetária no sangue total, que serviu de parâmetro para os valores alcançados no PRP. O protocolo no qual foi possível alcançar maior concentração plaquetária foi testado em outros 20 cães para avaliar sua reprodutibilidade. Constatou-se que o protocolo B resultou em maior plaquetometria em 100% das amostras e concluiu-se ser ele eficiente para a produção do PRP em cães.Palavras-chave: cão, fatores de crescimento, gel de plaquetas ABSTRACT The objective of this paper was to analyze two protocols for the production of platelet rich plasma (PRP) in dogs. Peripheral blood of 20 adult dogs was collected into three tubes. The first was processed throughprotocol A − single centrifugation at 1200rpm for 10min −, the second was submitted to protocol B -a first centrifugation at 1200rpm for 10min and a second centrifugation at 1600rpm for 10min − and the third was used to perform platelet count in whole blood, which served as a parameter for values obtained in PRP. The protocol in which it was possible to achieve a higher platelet count was tested in other 20 dogs to evaluate its reproducibility. Protocol B resulted in a superior platelet count in 100% of the samples, concluding that the referred protocol is effective for PRP production in dogs.
The objective of this study was to investigate the effects of a gel formulation from the association of Plectranthus neochilus and Cnidoscolus quercifolius on tissue repair in cutaneous wounds in rats. A surgical wound was induced in 35 Wistar rats and treated according to group: G1 - commercial phytotherapeutic gel; G2 - Carbopol gel 1%; G3, 4, 5 - gel formulation from Boldo-gambá and Favela (FGBF) at 2.5%, 5%, and 10%, respectively. 1ml of the product was applied topically daily, for 14 days. Macroscopic evaluation of the wound showed inflammation, granulation, and epithelization in all groups. The FGBF 2.5% group showed greater angiogenic potential. There was a significant difference between the surgical area of the wounds treated with FGBF 2.5%, 5%, or 10% compared to the group with the commercial phytotherapeutic gel. On histomorphometry of the skin, there were reepithelization of the epidermis and superficial dermis, longitudinal collagen fibers, fibroblasts, and blood vessels, and in the deeper dermis, fibroblasts, transverse and longitudinal collagen fibers, blood vessels, and inflammatory cells. The 2.5% formulation had the greatest increase in fibroblast proliferation and most intense collagenization on day 14 of treatment.
Influência da temperatura e do tempo de armazenamento nas dosagens bioquímicas de uréia e creatinina em soro ou plasma caninos RESUMOO trabalho teve como objetivos avaliar algumas condições de estocagem de soro e de plasma com EDTA 10% utilizados para determinação dos valores de uréia e creatinina em cães, e avaliar a possibilidade de substituir o soro pelo plasma conservado com EDTA 10%. Foram realizadas 3600 análises (1800 amostras de soro e 1800 de plasma) com amostras que permaneceram em temperaturas ambiente, de refrigeração e de congelamento. As análises foram realizadas imediatamente após a obtenção da amostra (tempo 0) e após 2, 6, 12, 24, 72 horas e 30 e 60 dias após a coleta do sangue. Os resultados permitiram concluir que a uréia conservou-se por mais tempo na amostra sérica refrigerada até 30 dias e a creatinina na amostra sérica congelada até 72h. O soro mostrou mais estabilidade que o plasma em todas as condições de estoque estabelecidas.Palavras-chave: Cão, uréia, creatinina, conservação ABSTRACTAiming to evaluating some conditions of EDTA 10% serum and plasma storage for urea and creatinine values determinations in canines as well as analyzing the possibility of serum substitution by plasma, a total of 3600 samples (1800 serum and 1800 of plasma) were analyzed at room, refrigeration and freezing temperatures. Different time intervals were used in the analysis: immediately after sampling (time 0), and at 2, 6, 12, 24, and 72 hours, and 30 and 60

Atualmente Médicos Veterinários atendem a animais de companhia, animais não convencionais e animais de produção, sendo desta forma, necessária a atualização e aprofundamento de seus conhecimentos para acompanhar o crescimento. A obtenção de conhecimento se inicia na faculdade com as práticas de ensino e se estende a vida profissional, através de especializações, pós-graduações e leitura de artigos, com esta visão foi compilado as pesquisas neste segundo volume de Estudos em Medicina Veterinária com temas inovadores dentro da clínica médica, nutrição, produtos de origem animal e práticas de ensino.
