Abstract The effects of administration of two promoters of hepatocarcinogenesis on five hepatic biochemical parameters were examined in adult female rats. Two treatments of phenobarbital (100 mg/kg) 21 and 4 hours before sacrifice caused large increases in hepatic ODC activity and cytochrome P-450 content. Extending the number of phenobarbital treatments to 5 increased the size of hepatic enzyme induction and caused a minor decrease in hepatic glutathione and a small increase in serum alanine aminotransferase. Two administrations of butylated hydroxytoluene (BHT) (700 mg/kg) caused hepatic DNA damage and induction of both ODC activity and cytochrome P-450 content. Of the two compounds only BHT showed a potential for carcinogenic initiation. The biochemical parameters studied here, may form a useful biochemical system to examine a compound's potential to cause carcinogenic initiation, carcinogenic promotion and cellular toxicity.
