Abstract

To investigate the mechanism of Fuzheng Huayu recipe (FZHY), a compound traditional Chinese herbal medicine, against liver fibrosis related to transforming growth factor-β1 (TGF-β1)/Smads signaling transduction. The research consisted of in vitro and in vivo experiments. In the in vivo experiment, 37 male Wistar rats were divided into 3 groups: 5 rats in normal group, 18 and 14 rats respectively in model and FZHY groups. Liver fibrosis was induced in rats of the model group and the FZHY group by intraperitoneal injection of dimethylnitrosamine with a dose of 10μg/kg body weight for 4 weeks. Rats in the FZHY group were administered with FZHY for 4 weeks after liver fibrosis was induced. After the treatment of FZHY, hydroxyproline (Hyp) content in rat liver tissue was assayed by Jamall's method and protein expressions of TGF-β1, TGF-β1 receptor I (TβR-I), Smad2, Smad3 and phosphorylated-Smad2/3 were analyzed by Western blotting. In the in vitro experiment, hepatic stellate cells (HSCs) were isolated from normal rats by in situ pronase/collagenase perfusion followed by density gradient centrifugation. On the 4th day of cell culture, HSCs were stimulated by 2.5 ng/mL TGF-β1 for 24 h, then incubated with the medium containing 10% FZ...Continue Reading
