The results showed that SMB had significant effect inhibiting lipid peroxidation of the hepatocytes when exposed to CCl4 as compared with the non-protective co4trol. SMB could decrease the production of malondialdehyde (MDA) and the release of ALT, and increase the synthesis of albumin (ALB) and the activity of Se-dependent glutothione peroxidase (Se-GSH-Px). These results suggest that the suppression of lipid peroxidation may be largely due to the increased activity of Se-GSH-Px.展开更多

In the cultured hepatocytes injured by CCl4,significant increments of the MDA production and the ALT release,and significant decrease in the plasma membrane fluidity were observed.when the culture medium was supplied with SMB prior to the additionof CCl4,the CCl4 induced increments in MDA production and ALT release was suppressed signifi cantly and a concomitant raise of plasma membrane fluidity towards normal occurred.The resultssuggested that SMB could suppress the lipid peroxidation in bepatocytes,thereby normal membranefluidity might be retained.展开更多
