The question as to whether CCl4 decreases the activities of glucose-6-phosphatase and cytochrome P-450 in liver endoplasmic reticulum mainly through its action in stimulating lipid peroxidation has been investigated using Promethazine to block lipid peroxidation. The investigation, moreover, has compared the effects of CCl4, with and without Promethazine, on isolated rat hepatocytes with corresponding effects on rat liver microsomal suspensions. Our data give no support for the view that products of lipid peroxidation are the main cause of the decrease in cytochrome P-450 observed in CCl4-intoxication. However, our present results are consistent with lipid peroxidation being a major contributory factor to the decrease in glucose-6-phosphatase activity observed in CCl4-induced liver injury.
