초록

To compare the severe liver damage with the slight one on the bromobeazene metabolism in rats, the animal group described as B7 group was induced the stage of slight liver damage with 7 times bromobenzene injection every other day (400 mg/Kg body wt. i.p.), whereas B40 group was induced that of more severe liver damage with bromobeazene 40 times injection as identified with determination of serum levels of alanine aminotransferase(ALT) activity and the histopathological findings. In the present experimental animal model, the decreasing rate of glutathione(GSH) and the increasing rate of glutathione S-transferase activity to the control group were higher in B7 group than B40 group. Furthermore the single dose of bromobenzene was injected to the two groups and sacrificed at 8hr and the hepatic aniline hydroxylase(AH) activity, GSH content and GST activity were determined. The increasing rate of AH activity to the control was lower in B40 group than B7 group and the decreasing rate of GSH to the control was also lower in B40 than B7 group. Moreover, B7 group showed the increased activity of hepatic GST to the control whereas B40 group showed the decrease activity of the enzyme. And Vmax value in GST was more decreased in B40 group than B7 group.
