RESUMO
In this study we report the hematological, biochemical and hormonal parameters in a juvenile male Amazonian manatee measured before transport, immediately after transport, and during adaptation to a new facility. The animal was transported from Manaus, Amazonas, Brazil, to São Paulo, São Paulo, Brazil, (2,733 km) within 6 hours. Among all blood parameters analyzed, we observed obvious neutrophilia, lymphopenia, and increases in the neutrophil/lymphocyte ratio and serum glucose and aspartate aminotransferase (AST) levels, but these parameters subsequently returned to normal. These results suggest that transport and changes in the environment are temporary stressful events for Amazonian manatees. We, therefore, recommend monitoring the hematological and biochemical parameters before and after translocation to minimize the effects of handling stressors in this species

RESUMO
Aiming to offer the anatomical bases for epidural anesthesia, particularly relative to the topographical anatomy of the medullar cone, three specimens of adult giant otter (Pteronura brasiliensis), two male and one female, after natural death, were dissected. Those animals were donated from Laboratory of aquatic mammals (INPA National Institute for Amazonia Research). After the dissection were observed: a) in two animals (66.6%), one male and one female, the medullar cone apex is close to fourth lumbar vertebra (L4) and, in other one animal (33.3%), male, between the L3 and L4 vertebrae; b) the medullar cone length is 5.50cm in alls animals to this study, and your base is close to L3 (66.6%) or between the L2 and L3 vertebrae (33.3%); c) the lumbar enlargement (Intumescentia lumbalis), that continuous to the base of the medullar cone, were noted between the T12 and L2 vertebrae. KEY WORDS: Anatomy, medullar cone, Pteronura brasiliensis.
Com o propósito de disponibilizar dados anatômicos que sirvam de base para a prática das anestesias epidurais, em especial aqueles relativos à topografia do cone medular, foram dissecados três exemplares adultos de ariranha (Pteronura brasiliensis), dois machos e uma fêmea, após morte natural, provenientes do Laboratório de Mamíferos Aquáticos, do Instituto Nacional de Pesquisas da Amazônia (INPA). Após as dissecações, observou-se que: a) o ápice do cone medular encontra-se ao nível da quarta vértebra lombar (L4) em dois animais (66,6%), sendo um macho e uma fêmea, e entre as vértebras L3 e L4 em um animal (33,3%) macho; b) o cone medular apresentou cerca de 5,50 cm de comprimento, nos três animais estudados, estando sua base sobre a vértebra L3 em dois animais (66,6%), ou entre as vértebras L2 e L3, em um espécime (33,3%); c) intumescência lombar, que se apresentou contínua com a base do cone medular, foi registrada entre as vértebras T12 e L2, nos três espécimes.PALAVRAS-CHAVES: Anatomia, cone medular, Pteronura brasiliensis.PALAVRAS-CHAVES: Pteronura brasiliensis, anatomia, cone medular.
