Estudo da vascularização arterial do baço em javalis (Sus scrofa scrofa, linnaeus - 1758)

Related searches to wild animals are growing more each day, yielding important information related to anatomy, physiology and behavior, essential for the survival of the animals. The spleen is an organ with multiple functions being responsible for the formation of blood cells, blood filtration and immune response. Although there are many studies on this organ segmentation in wild animals, there is not much information about this vascularization in Sus scrofa scrofa. The aim of this study was to describe the arteries distribution of the in the spleens of wild boars. To conduct the work we used 20 organs of animals from breeding. The carotid artery was isolated and injected with Neoprene Latex solution. The animals were fixed and spleens were dissected exposing the branches from the splenic artery. Analyzing the results we found similarities spleens characteristics of pigs, carnivores (dogs and cats) and opossums. However there were differences in the branches of the lienais arteries between the gender of the specie.

Topografia do cone medular de Ouriço-cacheiro (Coendou prehensilis, Linnaeus, 1758) (Rodentia)

The first proposed of caudal anesthesia was in 1926 and many techniques were developed to anesthetize the lumbar and sacral spinal nerves. This study determined the medullary cone topography of the Coendou prehensilis, using six adults from the Sabiá Park Zoo, Uberlândia-MG. The material was fixed in formaldehyde solution 10% in the LAPAS. The skin incision was done, then the spine muscles were removed and the vertebral arches were cut to visualize the spinal cord and the surrounding structures. The medullary cone in all the specimens began in the fourth lumbar vertebra (L4) and finished in the second sacral vertebra (S2), and the length changed to 5.9cm to 4.7cm. This study concluded that the best place for epidural anesthesia of the pelvic limb in the Coendou prehensilis is between the L4 and S2 vertebrae.

Anatomical Behavior of the Celiacomesenteric Artery of Pirarucu Arapaima gigas Cuvier, 1817 (Osteoglossiforme, Arapaimidae)

El pirarucu, pez de la familia Arapaimidae, es una de las especies mas importantes y emblematicas de la ictiofauna amazonica. Para estudiar las caracteristicas anatomicas de su sistema circulatorio, fueron utilizados 10 ejemplares de Arapaima gigas, con un longitud total media de 74 cm, provenientes de lagos del rio Araguaia, Sao Miguel do Araguaia, Goias, Brasil. A los peces se les abrio la cavidad celomatica donde se identifico y canalizo la arteria aorta dorsal, injectandose una solucion coloreada de latex sintetico. La fijacion del material se realizo con inyecciones de formol al 10%. La arteria celiacomesenterica es responsable de la irrigacion del tubo digestivo y tiene origen en las 2a, 3a y 4a arterias branquiales eferentes izquierdas. El estomago esta irrigado por la arteria celiaca y por una rama gastrica de la arteria cecal ventral. El intestino recibe ramas arteriales procedentes de la arteria celiacomesenterica y de las arterias mesentericas craneal y caudal; los ciegos dorsal y ventral estan irrigados por las arterias cecales dorsal y ventral, respectivamente
