Extract

Pathological changes of hepatocytes from rats fed a 30% ethanol-derived calories diet for three weeks include noticeable ultrastructural changes including steatosis and hypertrophy of the smooth endoplasmic reticulum. We sought to examine hepatocytes of deer mice administered ethanol in an inhalation chamber for two weeks to determine if subtle changes occur in hepatocyte organelles prior to steatosis.

Two strains of Peromyscus maniculatus, ADH-positive possessing hepatic cytosolic alcohol dehydrogenase and ADH-negative deer mice lacking this enzyme were purchased from the Peromyscus Genetic Stock Center (Univ. of South Carolina). They tested negatively for Hanta viruses. A morphometric analysis of the ultrastructure of ADH+(n=14) and ADH- (n=14) controls as well as experimentals exposed to chronic, intoxicating levels of ethanol was conducted. Blood ethanol levels were maintained between 1.25-1.75 mg/ml for two weeks in the experimentals.
