The Effects of Vitamin A and E on Lipid Peroxidation in Ethanol Administered Rat Liver Microsomes

Ethanol enhances the activity of microsomal enzyme system and lipid peroxidation. We observed the effect of chronic ethanol administration on cytochrome P-450 level and lipid peroxidation in rat liver microsome. The results were as follows : 1) When rats were administered with ethanol, the level of microsomal cytochrome P-450 was decreased and lipid peroxidation did not change significantly. 2) When vitamin A and E were added incubation medium in each group, lipid per-oxidation was decreased significantly.
