Effects of Salvia Miltiorrhiza and Rrhizoma Alismatis on Lipid Metabolism and Fibrinolytic System in Rats with Non-alcoholic Fatty Liver / 中国药师

ABSTRACT

Objective:To preliminarily discuss the mechanism of Salvia miltiorrhiza and Rrhizoma alismatis in the prevention and treatment of lipid metabolism through regulating the imbalance of fibrinolytic system in rats with non-alcoholic fatty liver. Methods:The model of non-alcoholic fatty liver in rats was duplicated by high-fat diet feeding. Totally 60 adult Wistar rats were randomly divided into 6 groups (n=10 per group), namely the control group, the model group, Salvia miltiorrhiza group, Rrhizoma alismatis group, Salvia miltiorrhiza and Rrhizoma alismatis group,and Dongbaogantai group. The control group and the model group were given distilled water,and the other group was given Salvia miltiorrhiza,Rrhizoma alismatis,Salvia miltiorrhiza combined with Rrhizoma alismatis and Dongbaogantai,respectively. Rhizoma Alismatis decoction at high dose and low dose as well as Dongbaogantai was respectively adminis-trated in the designed groups,and the corresponding indices were detected 4 weeks later. Results:In the model control group,the con-tents of TC、TG、FFA in serum and the expression of PAI-1 were significantly elevated(P<0.05 or P<0.01),while the expression of t-PA was significantly reduced(P<0.01).After treatment,the contents of TC、TG、FFA in serum and the expression of PAI-1 in every treatment groups were reduced(P<0.01),while the expression of t-PA was elevated(P<0.01).Conclusion: Increasing the expres-sion of t-PA and reducing the expression of PAI-1 might be viewed as the mechanisms of Salvia miltiorrhiza and Rrhizoma alismatis in the prevention and treatment of non-alcoholic fatty liver disease.
