ABSTRACT

The objective of the research was to evaluate the efficiency of the spermatogenesis through the morphology of the testicular parenchyma in bulls of different zebu breeds. We used testicular fragments from bull of the breeds Nelore (n = 10), Polled Nelore (n = 6), Gyr (n = 5), Guzerat (n = 5) and Tabapuã (n = 5). The tissue was perfused with Karnovsky solution, included in glycol methacrylate and stained with toluidine blue-sodium borate 1%. Animals of the Nelore breed presented higher population of primary spermatocyte in pre-leptotene/leptotene (38.30) and in pachytene (38.14) and round spermatids (113.30), higher yield of spermatogonia mitosis (21.2) and higher daily spermatic production per gram of testicular parenchyma (32.8 × 10(6) ) than those from breeds Gyr, Guzerat and Tabapuã and higher general yield of spermatogenesis (62.4) than breeds Gyr and Tabapuã. There was no significant difference in any of the evaluated parameters between breeds Nelore and Polled Nelore. The rate of Sertoli cells did not vary between the studied breeds. Apparently, the genetic selection applied to the breeds has been improving the yield in the spermatogenic process by decreasing cellular loss, although it did not increase the support capacity of the Sertoli cells.

RESUMO.Descreve-se um caso de atendimento a animal, felino, adulto, fêmea, com diagnóstico de hérnia diafragmática crônica tendo o útero gravídico em fase final de gestação como parte do conteúdo herniário. O gradativo crescimento fetal no decorrer da gestação determinou importante comprometimento respiratório. A gravidade do quadro exigiu interrupção cirúrgica da gestação com posterior herniorrafia por flape peritoneal, porém não houve êxito e o animal veio a óbito ao final do procedimento cirúrgico. O óbito foi atribuído à cronicidade e gravidade da condição clínica em que se encontrava. Este relato ressalta a importância da correção imediata de hérnias diafragmáticas e do acompanhamento pré-natal durante a gestação.

A case of animal care, feline, adult, female is described, with diagnosis of chronic diaphragmatic hernia with the gravid uterus in the final stage of gestation as part of the hernial content. Gradual fetal growth during pregnancy led to significant respiratory impairment. The severity of the condition necessitated a surgical interruption of gestation with posterior herniorrhaphy with peritoneal flap, but it did not succeed and the animal died at the end of the surgical procedure. The death was attributed to the chronicity and severity of the clinical condition in which it was found. This report highlights the importance of immediate correction of diaphragmatic hernias and prenatal follow-up during pregnancy.

Se describe el reporte de un caso de una felina adulta, en fase final de gestación con diagnóstico de hernia diafragmática crónica conteniendo útero con fetos. El progresivo crecimiento fetal durante el transcurso de la gestación determinó una importante complicación respiratoria. La gravedad del cuadro requirió de la interrupción quirúrgica de la gestación con posterior herniorrafia por flape peritoneal, pero no hubo éxito y el animal murió al final del procedimiento quirúrgico. El fallecimiento fue atribuido a la cronicidad y gravedad de la condición clínica en que se encontraba. Este reporte resalta la importancia de la corrección inmediata de hernias diafragmáticas y del acompañamiento prenatal durante la gestación.

The occurrence of gallstones in dogs is rare, consisting, usually, in accidental findings. The animals affected present nonspecific clinical signs or even may be asymptomatic. However, depending on the localition of the stone, can occur total obstruction of bile flow and cause rupture of gallbladder or bile ducts. The imaging exams, such as radiography and/or abdominal ultrasonography, and their correct interpretation are fundamental for evaluation of biliary system. The objective of the present review is a description of the radiographic images and ultrasonographic characteristics of cholelithiasis and choledocolithiasis in dogs.

Os tumores vaginais e vulvares compreendem as neoplasias mais frequentes do trato reprodutivo tubular em cadelas. O leiomioma é uma neoplasia benigna de origem mesenquimal de músculo liso, frequentemente diagnosticada no trato genital, principalmente em vagina e útero. A desregulação hormonal em cadelas não castradas pode favorecer o surgimento desta neoplasia. Caracterizam-se macroscopicamente como massa de crescimento lento, bem encapsulada e pouco vascularizada. Este relato descreve dois casos, um vaginal e um uterino, atendidos no Hospital Veterinário da Faculdade de Medicina Veterinária e Zootecnia da Fundação Universidade Federal do Mato Grosso do Sul.
