Abstract 1. Various polychlorinated hydrocarbons were administered intragastrically to rats to examine their effects on the biotransformation capacity of the liver. Due to high toxicity, 1,1,2,2-tetrachloroethane and pentachloroethane were given at a dose level equivalent to one quarter of that of CCl4 and the other chlorohydrocarbons (i.e. 2-6 mmol/kg). 2. Carbon tetrachloride at 10-3 mmol/kg was the most active in decreasing cytochrome P-450 content and the overall drug hydroxylation activities in rat liver. 1,1,2,2-Tetrachloroethane was the next most active in decreasing the hepatic drug oxidizing enzymic activities. 3. Expoxide hydratase activity in rat liver declined significantly after CCl4, 1,1,2,2-tetrachloroethane and pentachloroethane administrations. 4. UDP-Glucuronosyltransferase was affected to a lesser extent than the microsomal mono-oxygenase or epoxide hydratase by chlorohydrocarbon treatment.
