Abstract
There is evidence to suggest that the mechanism of antioxidant effect of prostaglandin E1 (PGE1) is due to decrease of radical species generation by cytochrome P-450 in rat liver microsomes. Chronic alcohol intoxication increased NADPH oxidation, cytochrome P-450 content and NADPH-stimulated chemoluminiscence of microsomes. Ethanol also raised superoxide dismutase (SOD) activity in microsomes. PGE1 decreased cytochrome P-450 content, normalized NADPH oxidation, NADPH-induced chemoluminiscence and SOD activity in the liver of alcohol-treated rats. PGE developed the similar effect after microsomal induction by both acetone combined with starvation and phenobarbital normalizing all the above parameters. Therefore, PGE1 affects on both, ethanol-inducible IIE1 and phenobarbital-inducible IIB1 isoforms.
