RESUMO.-O preá é um roedor típico da caatinga pertencente à família Caviidae. Considerando a inexistência de dados sobre o arco aórtico do preá, foi realizado este estudo tendo como objetivo descrever os ramos colaterais do arco aórtico neste cavídeo, e dessa forma, contribuir com dados para biologia da espécie. Foram utilizados vinte preás machos provenientes de estudos anteriores e encontravamse armazenados em freezer no Centro de Multiplicação de Animais Silvestres (CEMAS/UFERSA). Os animais foram descongelados, a cavidade torácica foi aberta, a aorta canulada e o sistema vascular lavado com solução salina e em seguida, injetado látex Neoprene corado com pigmento vermelho, amarelo ou branco. Posteriormente, os animais foram fixados em formol e depois de 72 horas, dissecados e analisados, sendo obtidos desenhos esquemáticos e os exemplares mais representativos fotografados. O arco aórtico do preá emitiu como ramos colaterais, o tronco braquiocefálico e a artéria subclávia esquerda. O tronco braquiocefálico originou na maioria das peças estudadas, a artéria carótida comum esquerda e o tronco braquiocarotídeo, do qual surgem as artérias subclávia direita e caróti-da comum direita. As artérias subclávias direita e esquerda em todos os animais estudados emitiram a artéria verte- Galea spixii is a typical rodent of the caatinga belonging to the Caviidae family. Considering the lack of data on the aortic arch of the galea, this study aimed to describe the collateral branches of the aortic arch in this specie and to contributes to knowledge of its biology. Twenty males from previous studies were used which had been stored in a freezer at Multiplication Center of Wild Animals (CEMAS/UFERSA). The animals were thawed, the thoracic cavity was opened and the aorta cannulated vasculature was washed with saline and then injected with Neoprene latex colored with red pigment, yellow or white. Subsequently, the animals were fixed in formalin and after 72 hours dissected and analyzed, to obtain schematic drawings and the most representative samples were photographed. The cavy aortic arch issued as collateral branches, the brachiocephalic trunk and the left subclavian artery. The brachiocephalic trunk afforded in most of the specimens the left common carotid artery and the brachiocarotid trunk, where the right subclavian and right common carotid arteries arise. The right and left subclavian arteries in all animals studied issued the vertebral artery, internal thoracic artery, superficial cervical artery costocervical trunk and axillary artery. The pattern of formation of the aortic arch of galea was similar to that observed in other rodents, such as the kerodon, the guinea pig and chinchilla.
Título: Análise cinética da locomoção aplicada á técnica de transposição do músculo semitendinoso na reparação de hérnia perineal bilateral em cães A hérnia perineal é uma das afecções cirúrgicas frequentemente observadas na rotina da clínica cirúrgica de pequenos animais e acometem na sua maioria, cães machos, não castrados e acima de cinco anos. Apresenta elevado índice de recidivas e complicações pós-cirúrgicas, e devido a este fato, muitas técnicas foram preconizadas e utilizadas para a sua correção. Os were used as parameters for the analysis of changes in locomotion. The PFV and IV showed no statistical difference (p> 0.05) between the operated and non operated limbs, respectively (18.62 ± 4.93 and 18.51 ± 3.75), indicating that there was no change in locomotion dogs after the transposition of the semitendinosus muscle. The difference in behavior of these variables in the preoperative period allowed us to infer that the discomfort caused by perineal hernia can interfere with the locomotion of the asymmetry animal generating, whereas after the operative procedure, the symmetry of locomotion showed more next values of the normal.The difference in PFV and IV, although not significant, gives us an idea of the recovery of these dogs and suggests that the transposition does not affect the motor function of the limb.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
