ABSTRACT
The present paper deals with the modulatory influence of camphor on the activities of hepatic phase I and phase II drug metabolising enzymes and the levels of hepatic and extrahepatic reduced glutathione contents in the mouse. Female Swiss albino mice (8-9 weeks old) were treated daily by oral route for 20 days with 50, 150 or 300 mg/kg body weight of camphor dissolved in 0.1 ml of olive oil. Camphor only at the 300 mg/kg body weight dose level caused a significant increase in the activities of cytochrome P450 (P < 0.05), cytochrome b5 (P < 0.05), aryl hydrocarbon hydroxylase (P < 0.05) and glutathione S-transferase (P < 0.05). These modulatory effects were comparable with those induced by 0.75% BHA diet given for 20 days (positive control group). The reduced glutathione level was elevated significantly in liver (P < 0.05) by camphor only at the 300 mg/kg body weight dose level and in liver, lung and stomach (P < 0.05) by BHA.
