Effects of Sinomenium acutum Polysaccharide on Oxidative Stress and Hepatocyte Apoptosis in Mice with Acute Alcoholic Liver Injury
摘要
Abstract
OBJECTIVE:To explore the protective effect and its mechanisms of Sinomenium acutum polysaccharide on mice with acute alcoholic liver injury. METHODS:60 mice were randomly divided into blank control group (normal saline),model group (normal saline),bifendate group (positive control,150 mg/kg) and S. acutum polysaccharide low-dose,medium-dose, high-dose groups(100,200,400 mg/kg),10 in each group,intragastrically administrated,once a day,for continual 7 d. 1 h af-ter last administration,mice received 50% ethanol (0.1 mL/10 g) intragastrically to induce acute alcoholic liver injury model ex-cept for those in blank control group. After 12 h,alanine aminotransferase(ALT),aspartate aminotransferase(AST)levels in se-rum,malondialdehyde(MDA),superoxide dismutase(SOD),glutathione(GSH),glutathione peroxidase(GSH-Px)levels in liv-er tissue of mice were determined;hematoxylin-eosin staining was conducted to observe the pathological changes in liver tissue;flow cytometry was used to detect the cell apoptosis rate. RESULTS:Compared with blank control group,mice in model group showed pathological changes in edema,disordered cell arrangement and local necrosis;ALT and AST levels in serum,MDA level in liver tissue and hepatocyte apoptotic rate were significantly increased,while the SOD,GSH and GSH-Px levels in liver tissue were significantly decreased,with statistical significances (P<0.01). Compared with model group,cell degeneration and necrosis degree of mice were improved in S. acutum polysaccharide medium-dose and high-dose groups;except for cell apoptosis rate of liver in S. acutum polysaccharide low-dose group was not decreased significantly,the above-mentioned indicators in other treatment groups were significantly improved(P<0.05 or P<0.01). CONCLUSIONS:S. acutum polysaccharide shows obvious protective effect on mice with acute alcoholic liver injury,its mechanism might re-late to anti-oxidation stress and inhibiting hepatocyte apoptosis.关键词
