Com o objetivo de desenvolver um modelo de hemodiálise (HD) em cães, foram estudados 18 animais, sem raça definida, machos, clinicamente sadios, com peso corporal variando entre sete e 14 kg. O acesso vascular foi obtido através de implantação do cateter de duplo lúmen em veia jugular externa. As sessões de HD, em número de cinco por animal, com até três horas de duração, foram realizadas em hemodialisadora de sistema proporcional com ultrafiltração (UF) controlada, com solução dialisante padrão e tampão bicarbonato. A UF foi ajustada para HD isovolêmica, utilizou-se perfil de sódio, e para anticoagulação heparina sódica. Os animais foram mantidos anestesiados com cloridrato de levomepromazina e propofol. Foram avaliados dados hematológicos, bioquímicos, hemogasometria, pressão arterial sistêmica e tempo de coagulação ativado. Foi observada diminuição do número global de hemácias, volume globular, hemoglobina e leucócitos. Em relação aos exames bioquímicos, houve manutenção nos níveis de sódio sérico, e quanto à hemogasometria, a manutenção da SO2. A pressão arterial sistêmica manteve-se constante. Os resultados obtidos no presente trabalho permitiram concluir que foi possível o desenvolvimento do modelo proposto e mostrou que a HD em cães é um método viável e seguro, que poderá contribuir para o tratamento clínico da insuficiência renal nesta espécie.

The present study evaluated the liver with homogeneous parenchyma in dogs, with diffuse reduced echogenicity (G1), increased echogenicity (G2) and normal echogenicity (G3) by ultrasound examination associating the findings on animal profile, liver size and hematology and biochemistry results. Blood samples obtained by cephalic or jugular venipunture were submitted for hemogram and ALT, ALP, total proteins, albumin, globulin, urea and creatinine analysis. Among the 30 dogs in G1, 30 (100%) presented portal venous and gall bladder wall clarity, 23 (76.67%) presented normal liver size and edges, 15 (50%) were from 1 to 6 years old and 8 (26.67%) belonged to the lhasa apso breed. No predispositions were found according to gender, as well as no significant alterations in biochemical and hematological exams were observed in G1. The most prevalent disease found in this group was gastroenteritis (43.33%). Among the 30 dogs in G2, 27 (90%) presented hepatomegaly and rounded hepatic edges, 18 (60%) were over 9 years old, 16 (53.33%) were female and 9 (30%) belonged to the poodle breed. The laboratorial findings related to this group were increased ALT and ALP serum activity, decreased levels of total protein, albumin, globulin, erythrocytes and hematocrit, as well as leukocytosis with neutrophilia and a left shift, eosinopenia, lymphopenia and monocytosis. The most prevalent diseases found in this group were metabolic disorders (54%), such as diabetes mellitus and hyperadrenocorticism, and chronic hepatopathies (17%) due to prolonged and continuous use of corticoid and anticonvulsive drugs. Among the 30 dogs in the control group (G3), normal liver size and edges were presented in 22 (73.33%). In this group, no alterations were seen in laboratorial exams.

The Brown brocket deer (Mazama gouazoubira) is the most common free-living and captive deer in South America, especially in Brazil, and has great ecological and scientific significance. However, data on hematological and biochemical parameters in brown brocket deer are scarce. The goal of this study was to establish reference ranges for hematological and biochemical parameters of Mazama gouazoubira, comparing differences during the seasons of the year and between sex. Blood samples from ten adult healthy brown brocket deer (6 female and 4 male) were collected during daytime, monthly, during 12 months. The animals were maintained in individual stable, protected from noise and fed ad libitum with commercial ration and green fodder. For blood collection, animals were submitted to physical restrain for no longer than 2 minutes. The following parameters were determined: red blood cell count (RBC), haemoglobin concentration, packed cell volume (PCV), mean corpuscular volume (MCV), mean corpuscular haemoglobin (MCH), mean corpuscular haemoglobin concentration (MCHC), white blood cell count (WBC), platelet count, enzyme activity of alanine aminotransferase (ALT), aspartate aminotransferase (AST) and gamma-glutamyl transferase (GGT) and serum levels of alkaline phosphatase (ALP), creatine kinase (CK), total protein (TP), albumin, cholesterol, total calcium, ionic calcium, sodium, potassium, magnesium, triglycerides, creatinine and urea. Values were compared according to season and sex. RBC count, WBC count and MCV suggested seasonal influence. Haemoglobin concentration, PCV and MCV were influenced by sex. Serum concentration of total calcium, ionic calcium, sodium, potassium and magnesium were influenced by season. Serum magnesium was also influenced by sex. The blood parameters herein reported may be useful as reference values for diagnostic and prognostic purposes in captive brown-brocket deer.

O município de Rio Claro, localizado na região central do estado de São Paulo, durante o auge da era do café, da imigração tanto estrangeira como regional e da instalação de várias empresas, dentre elas a Companhia Paulista de Estradas de Ferro se urbanizou num acelerado ritmo, assim como tantas outras cidades do Brasil. Como resultado o aglomerado urbano cresceu, necessitando que seu perímetro expandisse para a zona rural, comprometendo tanto o seu patrimônio histórico quanto o cultural. Antigas propriedades datadas do final do século XIX que resistem à ação do tempo e mantém viva a riqueza e a cultura da época dão lugar à cidade. Esse processo é observado no bairro rural do Sobrado, localizado na região norte de Rio Claro, que vem sofrendo diretamente com a expansão urbana através da criação de novos loteamentos residenciais e comerciais. Portanto, o avanço da urbanização tem provocado à degradação e/ou desaparecimento dos fatos históricos e culturais ainda presentes nos bairros rurais do município

This study presents a new recombinant protein that acts as a powerful antiviral (rAVLO—recombinant Antiviral protein of Lonomia obliqua). It was able to reduce the replication by 106 fold for herpes virus and by 104 fold for rubella virus. RT-PCR of viral RNA rAVLO treated infected cells also showed similar rate of inhibition in replication. The analysis of this protein by bioinformatics suggests that this protein is globular, secreted with a signal peptide and has the ability to bind to MHC class I. It was found that there are several protein binding sites with various HLA and a prevalence of α-helices in the N-terminal region (overall classified as a α/β protein type). BLAST similarity sequence search for corresponding cDNA did not reveal a similar sequence in Genbank, suggesting that it is from a novel protein family. In this study we have observed that this recombinant protein and hemolymph has a potent antiviral action. This protein was produced in a baculovirus/Sf-9 system. Therefore, these analyses suggest that this novel polypeptide is a candidate as a broad spectrum antiviral.
