RESUMO

The aim of this study was to evaluate the stocking density for juveniles for two different species of characins (Astyanax bimaculatus and A. scabripinnis) in a recirculation system. An experiment was carried out with each type in which twelve tanks in each experiment were divided into four treatments (0.25, 0.75, 2.25 and 6.75 fish.L-1), in triplicate. At the end of cultures the stocking density 0.75 fish.L-1 showed greater weekly growth and final weight, for both species, and it is recommended for cultivation under similar conditions.(AU)

RESUMO

O objetivo do trabalho foi avaliar as características morfológicas como densidade numérica e espessura do pelame e comprimento dos pelos de vacas Holandesas predominantemente negras, puras por cruza em lactação na região de Montes Claros no norte de Minas Gerais. O estudo foi conduzido em duas fases, A: julho/agosto e B: outubro/novembro de 2010, utilizando 12 fêmeas Holandesas em lactação, puras por cruza de pelame predominante negro. Foram medidas as características de densidade numérica (nº pelos/cm²), espessura (mm), comprimento (mm) e a temperatura da superfície do pelame (TPE). Os resultados mostraram que o pelame foi menos denso, com pelos mais curtos na fase B, no entanto a espessura não variou entre as duas fases. No período em que ocorreu maior densidade numérica houve menor TPE. As características do pelame das vacas Holandesas puras por cruza observadas indicam uma boa adequação às condições ambientais da região em estudo.


The aim of this work was to evaluate the morphological characteristics such as number density, coat thickness and length of predominantly black lactating graded Holstein cows, in the region of Montes Claros in the north of Minas Gerais. The study was conducted in two phases, A: July/August and B: October/November 2010, using 12 lactating female Holstein crossbred dairy cows with predominant black coat. We measured the characteristics of numerical density (number of hair/cm²), thickness (mm) length (mm) and coat surface temperature (CST). Three samples of hair of each animal were taken at each stage through adjusted pliers. The results showed that the coat was less dense, with shorter hair in phase B, and the thickness did not change in the two phases. In the period when the coat was denser, that is, phase A, there was lower CTS. The observed coat characteristics of graded Holstein cows indicate good adaptation to environmental conditions in the region.

RESUMO

A case of male pseudo-hermaphrodite in a six-month-old Pinscher dog with mild signs of agression towards other dogs is reported. The animal presented fibrous mass in clitorial region, with structure similar to a diminutive penis. Testicles were found in the abdominal cavity, uterus had normal size and localization and hypertrophic clitoris was seen during exploratory laparotomy. The histopathological examination revealed testicular tissue, composed of hypotrophic seminipherous tubules and exuberant stroma and uterus with normal histological appearance. Moreover, the animal presented high levels of testosterone.

RESUMO

Nephrogenic diabetes insipidus (NDI) is a rare disease characterized by renal inability to respond properly to arginine vasopressin due to mutations in the vasopressin type 2 receptor (V2(R)) gene in affected Kindreds. In most Kindreds thus far reported, the mode of inheritance follows an X chromosome-linked recessive pattern although autosomal-dominant and autosomal-recessive modes of inheritance have also been described. Studies demonstrating mutations in the V2(R) gene in a affected Kindreds that modify the receptor structure, resulting in a dys- or nonfunctional receptor have been described, but phenotypically indistinguishable NDI patients with a structurally normal V2(R) gene have also been reported. In the present study, we analyzed exon 3 of the V2(R) gene in 20 unrelated individuals by direct sequencing. A C(T alteration in the third position of codon 331 (AGC(AGT), which did not alter the encoded amino acid, was found in nine individuals, including two unrelated patients with NDI. Taken together, these observations emphasize the molecular heterogeneity of a phenotypically homogeneous syndrome.

RESUMO

É consenso que o alcoolismo é doença multifatorial e que qualquer programa de tratamento deve levar em conta fatores sócio-econômicos e psico-biológicos. Com o objetivo de implantar um programa de tratamento hospitalar de alcoolista coerente com o estabelecido acima em um hospital psiquiátrico da Rede Pública Estadual de Säo Paulo, entende-se que o passo inicial é o de conhecer o perfil da populaçäo de alcoolistas que procuram o Hospital "Prof.Cantídio de Moura Campos" em Botucatu, S.
