In order to study the relation of cytochrome P-450 with the protective action of SY-801 and SY-640 against 〓-induced UDS and 3H-BP binding to nuclear DNA, the effects of SY-801 and SY-640 on liver microsomal cytochrome P-450 were studied in mice. The results indicated that the liver microsomal cytochrome P-450 concentration and aminopyrine demethylase activity were significantly increased in mice pretreated with SY-801 150mg/kg or SY-640 150 mg/kg once daily for three days.
