Abstract
The microsomal cytochrome content and enzyme activity has been determined in liver, kidney, lungs and intestinal mucous from guinea pig males which were injected 25% ethanol intraperitoneally at a dose of 2 g per 1 kg of body mass. The changes in cytochrome P-450 and b5 content, amidopyrine-N-demethylase, aniline hydroxylase, p-nitrophenol hydroxylase. NADP.H-cytochrome-c-reductase activities in investigated organs of the animals have been found depending on the ethanol intoxication period (for 3, 6 or 14 days). Changes of the same type in microsomal enzyme activities have been discovered in liver, lungs and intestine, but not in kidney that is accounted for the substrate specificity and inducibility of the cytochrome P-450 some forms in extrahepatic tissues.
