Abstract:
OBJECTIVE:To study the improvement effect of Poria cocos peels water extract(PWE)on liver fibrosis in rats in-duced by carbon tetrachloride(CCl4). METHODS:84 rats were randomly divided into blank control group,solvent control group, model control group, positive control group (Compound biejia ruangan tablet, 0.75 g/kg), PWE low-dose, medium-dose, high-dose groups (0.9,1.8,3.6 g/kg,calculated by crude drugs),12 in each group. Except for blank control group and solvent control group(ip vegetable oil),other groups received CCl4-vegetable oil solution to reduce liver fibrosis model,ip. After model-ing,each administration group received related medicines,ig,other 3 groups received equal volume of normal saline,once a day, for 4 weeks. After administration,enzyme-linked immunosorbent assay was used to detect the aspartate aminotransferase(AST),al-anine aminotransferase(ALT),laminin(LN),hyaluronic acid(HA),hydroxyproline(Hyp)contents in serum and reduced gluta-thione (GSH),superoxide dismutase (SOD),malondialdehyde (MDA) contents in liver tissue of rats;HE staining and Masson staining were adopted to observe the pathological changes of liver tissue. RESULTS:Compared with blank control group,indexes of rats in solvent control group had no obvious changes(P>0.05). AST,ALT,LN,HA,Hyp contents in serum and MDA con-tent in liver tissue in model control group were significantly increased(P<0.05);GSH,SOD contents in liver tissue were signifi-cantly reduced(P<0.05);and liver tissue showed obvious fibrosis lesions. Compared with model control group,AST,ALT,LN, HA,Hyp contents in serum and MDA content in liver tissue in PWE medium-dose,high-dose groups were significantly reduced (P<0.05);GSH,SOD contents in liver tissue were significantly increased(P<0.05);fibrosis degree of liver tissue was obvious-ly relieved. CONCLUSIONS:PWE shows good improvement effect on liver fibrosis of rats induced by CCl4,which may be related to inhibiting the lipid peroxidation.
