Abstract:
Objective To study the effects of linderae on alcoholic-induced acute liver injury in SD rats. Methods Forty SD rats were randomly divided into normal group, model group, biphenyl double ester group,and radix lin-derae group. The levels of serum alanine aminotransferase ( ALT) ,aspartate aminotransferase ( AST) were detected with routine laboratory methods using an autoanalyzer. Histopathological changes were assessed by HE. The activities of superoxidedismutase ( SOD) and the level of malondialdehyde ( MDA) in liver homogenates were measured by spectrophotometry. The expression of interleukin-1β( IL-1β) ,nuclear factor-κB( NF-κB) , and tumor necrosis fac-tor-α ( TNF-α) in the liver were analyzed by immunohistochemistry. Results Compared with the normal group, the levels of serum ALT, AST in rats treated with radix linderae were significantly decreased. The activity of serum and liver tissue SOD was significantly increased. Furthermore, the levels of IL-1β, NF-κB and TNF-αwere signifi-cantly decreased after treatment with radix linderae ( P<0. 05 ) . Conclusion The results of our study indicate that extracts from radix linderae alleviate alcoholic liver injury, in part maybe by improving the SOD activity of liver tis-sue and by increasing the antioxidant capacity. Meanwhile, the ability of linderae to reduce proinflammatory cyto-kine has a direct protective effect on hepatocytes.
