Análise ultra-estrutural da túnica muscular do intestino delgado de cães preservado em diferentes meios

The present study evaluated twenty-five sarnples of the muscular layer of the small gut in dogs, which were preserved in a 300% sugar supersaturated. solution, 98% glycerin, 5% polyvinil-pirrolidona and tiomersal tincture at 1: 1000. The samples were maintained under conservation for 45 days and further submitted to ultrastructural assay by transmission electron microscopy. The cellular integrity was not entirely preserved when using the media, while the 300% sugar solution and 98% glycerin were the preservation conditions that better maintained the cellular ultrastructure.

Morfologia e biometria do ligamento apical do pênis de touros da raça Girolando

The aim of this study was to describe the morphology and biometry of the apical ligament of the penis of Girolando bulls. For this purpose, it was dissected 32 penis of Girolando bulls obtained from slaughterhouses and kept frozen until their dissection. The animals were 36 to 48 month old and weighted between 480 and 540kg. The origin of the apical ligament occurred at 15.1±2.9cm distally to the caudal loop of the sigmoid flexure and its insertion occurred at 1.4±0.7cm proximally to the neck of the glans. The length of the apical ligament was 19.9±2.6cm. The width was 1.9±0.6mm at its origin, 2.2±0.8mm at its insertion and 35.2±10mm at the insertion of the internal lamina of prepuce. The average thickness along its extension varied from 0.7 to 1.0mm. On the free portion of the penis the apical ligament involved predominantly the dorsum and the left side of the penis, and its attachment to the tunica albuginea varied along its extension. The apical ligament is firmly attached to the tunica albuginea on its origin, insertion and on the left side of the penis, but dorsally and on the right side of the penis this union is made only through loose connective tissue. Significant linear relation was observed between length and circumference of the penis with length of the apical ligament, but the relation between these penis parameters and the width of the apical ligament was low.

COMPARAÇÃO ENTRE AS TÉCNICAS ANATÔMICAS DE FORMOLIZAÇÃO,GLICERINAÇÃO E PREENCHIMENTO/CORROSÃO NO SISTEMA RESPIRATÓRIO DECÃES

The objective of the techniques of conservation of anatomical pieces is to preserve the morphology, consistency, color and flexibility of the same. Among the techniques currently used are formaldehyde, glycerin and fill/corrosion, which were compared in the present study. Four pieces were used in the evaluation of each technique. For formalinization, the lungs were washed, dissected and fixed in 10% formalin. For the glycerination technique, the organs were fixed in 10% formaldehyde, washed for 48 hours, and then dried in the shade. Sequentially, the organs were submerged in hydrogen peroxide 10 and again dried in the shade. Then, they remained submerged in absolute alcohol for two months, were removed, dried naturally, and submerged in glycerin for 30 days. For the filling/corrosion technique the lungs were washed, then submerged in

Aspectos da irrigação do nó atrioventricular e tronco do fascículo atrioventricular em bovinos mestiços Girolando

Estudaram-se aspectos da irrigacao do no atrioventricular e tronco do fasciculo atrioventricular, componentes do sistema de conducao do coracao. Para tanto, utilizaram-se trinta coracoes de bovinos femeas, mesticas Girolando, com idade entre 36 e 48 meses. Os mesmos foram dissecados, apos previa injecao das arterias coronarias direita e esquerda, com solucao corada de Neoprene latex 450, seguida pela fixacao dos coracoes em solucao aquosa de formol a 15,00%, pelo metodo de imersao. O no atrioventricular foi irrigado, isoladamente ou em associacao, pelo primeiro ramo septal do ramo interventricular paraconal (3,33%), ramo distal do atrio esquerdo (6,66%), ramo septal da arteria coronaria direita (46,66%), ramo proximal do atrio direito (76,66%) e ramo ventricular direito (76,66%). O tronco do fasciculo atrioventricular foi irrigado, isoladamente ou em associacao, pelo primeiro ramo septal do ramo interventricular paraconal (3,33%), ramo ventricular direito (60,00%), ramo proximal do atrio direito (60,00%), e com maior frequencia pelo ramo septal da arteria coronaria direita (70,00%). As anastomoses arteriais estiveram presentes em 76,66% dos casos e geralmente formaram circuitos junto as margens do sistema de conducao cardiaco.
