Abstract:
The effects of different vitamin E(VE) containing diets on lipid peroxi-dation and the degree of liver damage in rats were observed in the model of liver necrosis induced by galactosamine(D-GAL).The results were as follows: After 8 weeks, the basic levels of VE in plasma and liver tissue of the group fed VE-supplemented diet were significantly higher than that of the group fed normal VE diet, in the company with a significant lower basic plasma MDA level. At each time interval after D-GAL injection, the plasma and liver VE levels were found higher in the VE-supplemented group, and the content of GSH as well as the activities of SOD, GSH-Px, HPT were maintained satisfactorily while the MDA content and OCT, m-AST activities were very significantly lowered and the pathological changes of the liver were not so severe as compared with that in the normal VE diet group. It was noteworthy that the changes of almost all the parameters metioned above in the group fed VE-deficient diet went to an opposite direction to the VE-supplemented group. The results indicated that the VE-supplemented diet has a good liver protective effect, which may be established on the increased VE content and suppressed lipid peroxidation in the liver. VE-deficient diet could sharply reduce the VE content in the body and significantly intensify the susceptibility of liver to the harmful agents.
