Stereologic study of the cerebellar Purkinje cells submitted to alcoholic intoxication in Wistar rats

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 6 micrometer (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.
