Immunophenotyping lymphocyte and acute phase proteins in canine X-linked muscular dystrophy.

Duchenne Muscular Dystrophy (DMD) is the most common X-linked muscular disease affecting humans. The Golden Retriever Muscular Dystrophy model (GRMD) is considerthe most suitable for several studies. This assay aims to quantify lymphocyte subpopulations CD4, CD5, and CD8, and standardize, the serum electrophoretic profile, to understand their contribution to the pathologic process in normal Golden Retriever dogs (GR group) and dystrophic´s (GRMD group), through the umbilical cord blood, in dogs aged from 2 to 3 months (GR II and GRMD II), and in dogs over 1 year of age (GR III and GRMD III). No significant differences were observed between the CD8+ lymphocyte subpopulations of the groups studied. The CD4+ and CD5+ lymphocyte subpopulations were significantly higher in the GRMD III group compared to the GR III group. Twenty-two different proteins in the gel were identified. The serum concentrations of the proteins belonging to the GR I and GRMD I groups were significantly lower than those of the other groups. We show that expression of acute phase proteins are worst during the aging of the dogs. We hope to expand knowledge to better understand the GRMD model and the translational data.

Estudo morfométrico de rins em felinos domésticos (Felis catus) / Morphometric study on the kidneys of domestic cats (Felis catus)

A saúde renal tem ao longo dos últimos anos chamado atenção dos médicos veterinários, pois o comprometimento deste órgão na insuficiência renal crônica se apresenta como a maior causa de morbidade e mortalidade em felinos. O presente estudo propõe a caracterização biométrica dos rins de gatos, Felis catus, sob os aspectos macroscópicos (comprimento, altura, largura, peso e volume), mesoscópico (altura do córtex e da medula, e a sua inter-relação) e microscópica (volume glomerular), a fim de se estabelecer possíveis diferenças decorrentes de idade, sexo e simetria bilateral. Foram utilizados, rins de 30 animais da espécie Felis catus (gato deméstico), sendo 15 machos e 15 fêmeas com idade variando entre 3 meses a 15 anos, divididos em três grupos: grupo 1 (3-9 meses), grupo 2 (3-5 anos) e grupo 3 (acima de 10 anos)...

Renal health has over the last few years called attention of veterinarians, because the chronic failure of the kidneyu is a major cause of morbidity and mortality in cats. This paper proposes biometric characterization of the kidneys from cats, Felis catus, on the macroscopic aspects (length, height, width, weight and volume), mesoscopic (height of the cortex and medulla, and their inter-relationship) and microscopic (glomerular volume) in order to establish possible differences arising from age, gender and bilateral symmetry. It where used 30 kidneys of animals from specie Felis catus (cat), 15 males and 15 females with ages between 3 months to 15 years, divided into three groups: group 1 (3-9 months), group 2 (3 - 5 years) and group 3 (above 10 years)...
