Resumo: | Alcoholism is considered a physical dependence disorder. More than 18 million people are alcoholics in the USA and England and between 1/3 to ½ of them present some kind of physical disorder. In general the literature is focused on alcoholic trunk muscle disorders. These muscles have different embryological origins if compared to the masticatory muscles. The aim of this research was to evaluate the effects of alcohol on the masticatory muscles in order to compare them with the somitic muscles. For this purpose, 15 male Wistar rats weighing around 250g were used. The rats were divided into three groups: Normal control (N), Alcoholic (A) and Isocaloric (I). Slices of the masseter muscle, temporalis muscle and rectus abdominal muscle were harvested and submitted to histochemical reactions (m-ATPase: acid and alkaline pre incubation and NADH-TR). The myofibers were classified in SO, FOG and FG. The results showed atrophy of the fast fibers (FG and FOG) in the masticatory muscles but this atrophy was not statistically significant in this study (p< 0.05). On the other hand, significant atrophy occurred in the rectus abdominal muscle (p |

Mais de 18 milhões de pessoas nos Estados Unidos são alcoólatras e na Inglaterra, entre 1/3 à ½ delas apresentam algum tipo de desordem física. No geral a literatura está focada para as desordens que acometem os músculos do tronco. Esses músculos têm origem embriológica diferente dos músculos da mastigação. O propósito desta pesquisa foi avaliar o efeito do álcool sobre os músculos da mastigação (branquiméricos) no intuito de compará-lo com as alterações que ocorrem nos músculos do tronco (miotômicos). Para isso 15 ratos machos Wistar, pesando ao redor de 250g foram utilizados. Os animais foram divididos em três grupos: Controle normal (N); Alcoolizado (A) e Isocalórico (I). Fragmentos dos músculos masseter, temporal e reto do abdome foram coletados e submetidos às reações de m-ATPase (com pré-incubações ácida e alcalina) e NADH-TR. As fibras puderam ser classificadas como FG, FOG e SO. Os resultados mostraram atrofia das fibras de contração rápida (FG e FOG) nos músculos da mastigação, embora esta atrofia, não tenha sido significante entre os grupos estudados. Por outro lado, atrofia significativa foi observada no músculo reto do abdome. Baseado nestes resultados pode-se concluir que o efeito do álcool sobre os músculos elevadores da mandíbula (m. masseter e m. temporal) é diferente se comparado aos observados em músculos somíticos (m. reto abdominal).
