ABSTRACT
OBJECTIVE:To study the protective effect of tadehaginoside(TA)on liver fibrosis model mice induced by carbon tetrachloride(CCl4),and to investigate its mechanism. METHODS :Kunming mice were randomly divided into normal group , model group ,colchicines group (positive control ,0.2 mg/kg),TA low-dose ,medium-dose and high-dose groups (3,6,12 mg/kg),with 10 mice in each group. Those groups were intraperitoneally injected with 10% CCl4-olive oil solution (5 mL/kg)to induce liver fibrosis model twice a week ,for consecutive 8 weeks;except that ,the normal group was intraperitoneally injected with olive oil. From 3rd week ,the mice in each administration groups were given relevant medicine intragastrically ,normal group and model group were given constant volume 2% sodium carboxymethylcellulose solution intragastrically ,once a day ,for consecutive 6 weeks. The contents of ALT ,AST,HA and IL- 6 in serum of mice were test ed by ELISA. The contents of Hyp , SOD,MDA and GSH-Px in liver tissues were detected by spectrophotometry. mRNA expression of Col- Ⅰ,TIMP-1 and TIMP-2 in liver tissue was detected by RT-PCR. The protein expression of MMP- 2 and TGF-β1 in liver tissue was detected by Western blotting. RESULTS : Compared with normal group,the contents of ALT,AST,HA,IL-6,MDA and Hyp,the mRNA expression of Col- Ⅰ,TIMP-1 and TIMP- 2,as well as the protein exp ression of MMP- 2 and TGF-β1 were increased significantly ,while the contents of SOD and GSH-Px were decreased significantly (P<0.01). Compared with model group,the contents of ALT ,AST,HA,IL-6,MDA and Hyp ,the mRNA expression of Col- Ⅰ,TIMP-1 and TIMP- 2,as well as the protein expression of MMP- 2 and TGF-β1were decreased significantly ,while the contents of SOD and GSH-Px were increased significantly(P<0.05 or P<0.01). CONCLUSIONS :TA has a significant protective effect on liver tissue and anti-fibrosis effects in liver fibrosis model mice ,the mechanism of which may be associated with inhibiting lipid peroxidation and collagen synthesis , down-regulating the mRNA expression of Col- Ⅰ,TIMP-1 and TIMP- 2 as well as the protein expression of MMP- 2 and TGF-β1.
