Abstract:
OBJECTIVE: To study the effects of Bushen Rougan Recipe (BSRGR), a compound traditional Chinese herbal medicine, on hepatic fibrosis in rats induced by dimethylnitrosamine (DMN), and to explore its preliminary mechanism. METHODS: A total of 40 male Wistar rats were randomly divided into normal control group (n=10), untreated group (n=15), and BSRGR group (n=15). Except for the rats in normal control group, hepatic fibrosis in rats was induced by peritoneal injection of DMN for 4 weeks. And the rats in the BSRGR group were also intragastrically administered BSRGR within the 4-week course. At the end of the 4-week course, rats were all sacrificed. The liver functions were determined by automatic biochemistry analyzer, including serum total bilirubin (Tbil), alanine aminotransferase (ALT), aspartate aminotransferase (AST), and albumin. Expressions of connective tissue growth factor (CTGF) and collagen type I mRNA in liver tissue were detected by reverse transcription polymerase chain reaction. RESULTS: It was found that the serum Tbil level and the activities of AST, ALT were declined in the BSRGR group as compared with those in the untreated group (P<0.01). The serum albumin content in the BSRGR group was increased as compared with that in the untreated group (P<0.01). The expressions of collagen type I and CTGF mRNAs in the untreated group were higher than those in the BSRGR group (P<0.01). CONCLUSION: BSRGR can decrease the expressions of collagen type I and CTGF mRNAs in the rats with hepatic fibrosis, which may be one of possible mechanisms in treating hepatic fibrosis.
