Abstract:
OBJECTIVE:To study the preventive effect and mechanism of Wei medicine Kunlun snow chrysanthemum polysac-charides(KSCP)on carbon tetrachloride(CCl4)-induced acute liver injury in mice. METHODS:96 mice were randomly divided in-to normal group(normal saline),model group(normal saline),Biphenyl diester dropping pill(positive control,1.5 mg/10 g)and KSCP low-dose,medium-dose,high-dose groups (0.3,0.6,1.2 mg/10 g),16 in each group,with intragastric administration, once a day,for 10 d. Except for normal group,mice in other groups were intraperitoneally injected 1%CCl4 rapeseed oil solution to induce liver injury. After 24 h of modeling,the levels of alanine aminotransferase (ALT),aspartate aminotransferase (AST),tu-mor necrosis factor α(TNF-α),interleukin 1(IL-1)in serum,levels of malondialdehyde(MDA),superoxide dismutase(SOD) in liver tissue were detected;the liver,spleen indexes were calculated. Pathological changes of liver tissue were observed,patho-logical scoring was conducted. The protein expressions of apoptosis-related genes Caspase-3,Bcl-2,Bax in liver tissue were detect-ed. RESULTS:Compared with normal group,levels of ALT,AST,TNF-α,IL-1 in serum,MDA level in liver tissue and liver, spleen indexes in model group were obviously increased(P<0.01);SOD level in liver tissue was decreased(P<0.01);pathologi-cal changes in hepatocellular necrosis,degeneration and inflammatory cell infiltration,and pathological score in model group was obviously increased(P<0.01);caspase-3 protein expression and Bcl-2/Bax ratio in liver tissue in model group were obviously de-creased (P<0.01). Compared with model group,above-mentioned indexes in each administration group were obviously improved (P<0.05 or P<0.01). CONCLUSIONS:KSCP has certain preventive effect on CCl4-induced acute liver injury in mice,and its mechanism may be associated with anti-oxidation,anti-inflammation and regulation of apoptosis-related protein expressions.
