RESUMO -Motivo do estudo:Analisar o efeito do álcool sobre as células de Purkinje de ratos. Método: Ratos Wistar receberam oralmente soluções alcoólicas em diferentes concentrações 4%, 12% e 24%. Os animais foram sacrificados com 4, 8 e 12 semanas e os cerebelos foram clivados em cortes aleatórios e uniformemente isotrópicos e incluídos em parafina. Cortes de 6µm (H & E) foram analisados por estereologia. Resultados: As diferenças entre a densidade por área e densidade de superfície das células de Purkinje de todos os grupos experimentais (E) e os respectivos controles (C) foram significativas. Com 12 semanas, a densidade volumétrica da célula de Purkinje diminuiu entre os grupos C e E nas concentrações de 4% e 12%, mas não para a concentração de 24%, provavelmente devido a menor ingestão de líquido pelos animais. Conclusão: O álcool exerceu efeito tóxico sobre o corpo celular da célula de Purkinje nas três concentrações estudadas a partir de 4 semanas. PALAVRAS-CHAVE: cerebelo, estereologia, intoxicação alcoólica, célula de Purkinje. Stereologic study of the cerebellar Purkinje cells submitted to alcoholic intoxication in Wistar ratsABSTRACT -Background: to analyze the effect of the alcohol on the cells of Purkinje. Method: Wistar rats received alcoholic solutions orally in different concentrations 4%, 12% and 24%. The animals were sacrificed with 4, 8 and 12 weeks and the cerebella were randomly cut and embedded in paraffin. Sections of 6µm (H&E) were stereologically analyzed. Results: The differences among the density for area and density of surface of the cells of Purkinje of all of the experimental groups (E) and the respective controls (C) were significant. With 12 weeks the cell of Purkinje volume density decreased among the groups C and E in the concentrations of 4% and 12%, but not for the concentration of 24%, probably due to smaller liquid ingestion by the animals. Conclusion: The alcohol has toxic effect on the Purkinje cellular body in the three studied concentrations from 4 weeks.
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.
