Abstract:
The protective effect of vitamin E and the change in activity of enzymes at hepatic injury by carbon tetrachloride(CCl_4) were studied with histochcmical methods. 60 rats were devided into three groups(A,B,C). The group A was untreated control; the animals of group B and C were injected(i. m.) with 0.9% NaCl 1 ml/100g or vitamin E 1 ml/100g body weight qd for 7 days respectively and then treated with 30% CCl_4 0.05ml/l00g by adding to the solution of NaCl or vitamin E from 8th to 14th days. On the 15th day, rats were sacrificed for histochemical study of the liver parenchyma. The results showed that the activity of SDH, G-6-Pase, ATPase, 5-NT or AcP in liver lobules of groups B and C animals were changed conspicuously after treatment with CCl_4. The quantitative histochemistry of SDH and G-6-Pase was also consistent with these results. The activity of SDH, G-6-Pase, ATPase and 5-NT were inhibited, but of AcP was elevated. As compared with those in the rats of group A, the changes however in group B appeared more obviously than those in group C. The results indicated that CCl_4 of the given dose induced acute damage in liver cells, while vitamin E had important protective effect against acute liver damag induced by CCl_4.
