English abstract The pharmacological effects of the methylprednisolone in the treatment of the spinal cord lesion, have been researched. An experimental study was performed with twelve wistar rats subjected to a contusion lesion of the spinal cord, by the NYU system. The rats were divided in two groups; the MP group which received the methylprednisolone after the contusion lesion and the control group, which received a 0,9% physiological serum. An analysis of the recuperation of the functional movement of the rats was accomplished on the 2nd, 7th and 14th day after the contusion, utilizing the BBB test. On the fourteenth day the rats were sacrificed and the histological findings of the spinal cord lesion were analyzed. It was noted that the rats from the MP group exhibited an improvement in the recuperation of their functional movement compared to that of the control group, and the histological findings of the spinal cord lesion couldn't be correlated with the recuperation of their functional movement

Foi realizado estudo experimental com doze ratos wistar submetidos à lesão contusa da medula espinhal pelo sistema NYU. Os animais foram divididos em dois grupos: grupo MP, que recebeu metilprednisolona após a lesão contusa e o grupo controle, que recebeu soro fisiológico a 0,9%. Foi realizada análise da recuperação funcional locomotora utilizando-se o teste de BBB no 2º, 7º e 14º dias após a contusão. No décimo quarto dia, os ratos foram sacrificados e analisados os achados histológicos da medula lesada. Observou-se que os ratos do grupo MP apresentaram melhora na recuperação da função locomotora em comparação com o grupo controle e que os achados histológicos da medula lesada não puderam ser correlacionados com a recuperação da função locomotora
