Background: Galea (Galea spixii) are rodents which are especially distributed in the northeastern region of Brazil, and have economic importance as their meat is used as a source of protein by the regional population.  Currently, they have received attention from researchers in studies involving their morphology. Thus, seeking to contribute information that supports their sanitary management in addition to the lack of literature on their nervous system, our objective was to describe the arterial vascularization of the base of the brain in this species, in order to identify the arterial pattern and arterial circuit behavior, as well as possible variations in these vessels.Materials, Methods & Results: Brains were obtained from 20 animals (10 males and 10 females) aged between 11 and 12 months, obtained from the Wild Animal Multiplication Center (CEMAS) of the Federal Rural Semi-Arid University (UFERSA), under the approval of CEUA/UFERSA (case number 23.091.000653/2014-26 and opinion number 15/2014), euthanized according to anesthetic protocol recommended for rodents (resolution number 714/2002 of the CFMV/ UFERSA) and preserved frozen in a freezer for an average period of 30 days. The animals were thawed and a longitudinal incision was performed in the thoracic region to allow exposure of the aortic arch. Next, they were cannulated in the cranial direction and injected with

The Galea of the semi-arid northeast (Galea spixii Wagler, 1831) is a rodent belonging to the family Caviidae. Little literature is found on this species in relation to morphology, environmental and reproductive behavior. With a view to understanding the general morphology, particularly, in the innervation of the pelvic limb of this species, ponder the sciatic nerve, which is the largest of all the nerves of the body. 10 cavies were used (five males, five females) that they had died of natural causes, originating from breeders scientific, legally licensed by IBAMA, the UFRSA, Mossoró, RN. The animals were fixed after the death in an aqueous solution of formaldehyde 10% and after 48 hours of immersion in it, were dissected to expose the sciatic nerve. Thus, the data were compiled in tables and expressed in drawings and photographs. The pairs of sciatic nerves were derived from ventral roots L6L7S1 (70%) and L7S1S2 (30%) and were distributed by the deep gluteal muscles, biceps femural, semitendinosus and semimembranosus muscles.


O preá do semiárido nordestino (Galea spixii Wagler, 1831) é um roedor pertencente à família Caviidae. Pouca literatura é encontrada sobre essa espécie em relação a sua morfologia e seu comportamento ambiental e reprodutivo. Com o objetivo de entender a morfologia geral, em foco, na inervação do membro pélvico dessa espécie, neste trabalho, foi explorado o nervo isquiático, o qual é o maior de todos os nervos do organismo. Foram utilizados 10 preás (cinco machos e cinco fêmeas) que vieram a óbito por causas naturais, oriundos do Centro de Multiplicação de Animais Silvestres da Universidade Federal Rural do Semiárido (CEMAS/UFERSA). Os animais foram fixados após o óbito em solução aquosa de formaldeído 10% e, após 48 horas de imersão nessa solução, foram dissecados para exposição do nervo isquiático. Dessa forma, os dados obtidos foram compilados em tabelas e expressos em desenhos esquemáticos e fotografias. Os pares de nervos isquiáticos originaram-se de raízes ventrais de L6L7S1 (70%) e de L7S1S2 (30%) e distribuíram-se pelos músculos glúteo profundo, bíceps femural, semitendinoso e semimembranoso.

Resumo

O modelo de placenta artificial tem como finalidade recriar o ambiente intrauterino, mantendo a circulação fetal e realizando as trocas gasosas e, ao mesmo tempo, permitir a maturação pulmonar. A placenta artificial apresenta-se como uma estratégia de suporte extracorpórea para neonatos prematuros cujos pulmões ainda não estejam completamente desenvolvidos. Este sistema é composto basicamente por uma bomba centrífuga, um oxigenador de membrana e cânulas inseridas nos vasos fetais para renovação do sangue. As tentativas de desenvolver uma placenta artificial foram abandonadas em meados da década de 80, mas com os avanços tecnológicos, em especial com o surgimento dos oxigenadores de membrana de fibra oca e os oxigenadores não microporosos compostos de biomateriais, deixaram os pesquisadores esperançosos no desenvolvimento do modelo ideal de placenta artificial. Este artigo apresenta uma revisão dos fatos históricos e discute os avanços e perspectivas da utilização de modelos de placenta artificial na medicina veterinária.
