100mg香烟烟油,多氯联苯诱导大鼠肝S_9组分中芳香烃羟化酶代谢B[a]P为3-OH-B[a]P的活性分别升高约40,20倍,而代谢B[a] P生成6-OXY-B [a]P自由基产物却仅由多氯联苯诱导的S_9组分作用中才被观察到。
The activity of B [a] P 3-OH-B [a] P in the hepatic S9 fraction induced by polychlorinated biphenyls was increased about 40 and 20 times Metabolism of B [a] P to produce 6-OXY-B [a] P free radical was observed only by PCB-induced S_9 fractionation.
