Effect of matrine on transforming growth factor β1 and hepatocyte growth factor in rat liver fibrosis model

Objective:To observe the preventive and control effect of matrine on transforming growth factor（TCF- β1） and hepatocyte.growth factor（HCF） of liver fibrosis tissue in rals.Methods:A total of48 SD rats were randomly divided into A,B,C,D groups with 12 in each,group A as the normal control group and groups B.C,D as liver fibrosis models using composite modulus method with carbon tetrachloride（CCL4）.Group B was the model group,group C adopted γ— interferon lavage therapy in the second day of modeling,and group D adopted matrine lavage treatment,at 4 and8 weeks after treatment.Six rats were executed for detection of TGF- β1 and HGF,liver tissue histology and comparison fibrosis degree changes of rat liver tissue between groups.Results:Croups B,C,D showed a more significantly increased TCF- β1 at each time point compared with group A（P<0.05）;Group B showed a more significantly increased TGF- β1 than groups C and D at weeks 4 and 8（P<0.05）;group D showed a lowest level of TGF-β1,followed by groups C and B.HGF of group B decreased more significantly than A group at weeks 4 and 8（P<0.05）;HGF of groups C and D was significantly elevated at 4 and 8 weeks than groups A and B（P<0.05）,in which the group D showed the highest level of HGF.According to tissue histologic observation,rat liver tissue structure of group A was clear and normal,tissue structure of group B was destroyed with obvious fibrous tissue hyperplasia and fatty change of hepatic cells;groups C and D showed a slighter liver tissue damage,cell necrosis and connective tissue hyperplasia in collect abbacy than group B with a trend of obvious improvement.Conclusions:Matrine can reduce TGF- β1expression and enhance the activity of HGF,so as to realize the inhibition effect on liver fibrosis in rats.
