The main mechanism of the interfering effects of Ruanganhuazheng Pills (RP) on hepatic fibrosis was studied. Rat hepatic satellite cells (HSC) were separated and cultured with RP serum prepared in normal rats. JH3,D,Z TdR incorporation was used for detecting HSC proliferation; ELISA, for measuring the level of collagen I in HSC supernatant; RT PCR, for detecting the expression of mRNA of HSC procollagen α 2 (I) and, the isotope label method, for detecting the activity of MMP1 in HSC supernatant. The results showed that RP-serum could inhibit HSC proliferation and the secretion of collagen I, increase the activity of MMP1, decrease the expression of mRNA of procollagen α 2 (I), which implies that the mechanism of the effects of RP for interfering hepatic fibrosis may be its inhibiting the activation of HSC.
