Abstract
Maternal ingestion of alcohol produce not only change of drug metabolism but also proliferation of hepatic smooth endoplasmic reticulum and many developmental defects of the central nervous system.
The present investigation examined the effects of maternal consumption of alcohol during pregnancy and/or lactation the activities of electron transfer components, mixed function monooxygenase, UDP-glucuronosyltransferase and lipid peroxidation of neonatal rat liver microsomes. Normal group consisted of neonatal rats whose mothers received standard chow and water. The subject of experimental group were neonatal rats whose mothers were exposed to alcohol during pregnancy and lactation(3 weeks).
The results were obtained as follows :
The activities of the electron transfer system, such as cytochrome P-450, NADPH-cytochrome C reductase were increased in hepatic microsomes of experimental group.
The activities of the mixed function monooxygenase, p-nitroanisole-O-demethylase and the conjugated enzyme, UDP-glucuronosyltransferase were increased in hepatic microsomal experimental group. There was no significant differences between the formation of lipid peroxide of normal and experimental group.
These results suggest that prenatal exposure to alcohol are influenced by disturb of liver microsomal drug metabolism, especially during the fetal period.
