Abstract | BACKGROUND: METHODS: RESULTS: The relative indicators of changes in histopathology, HA, LN, CIV, PCIII, Hyp, alpha-SMA and pp38 were raised significantly in the induced fibrosis group (P < 0.01 vs normal group). The semiquantitative hepatic fibrosis staging scores of middle dose group and high dose group were decreased (P < 0.05 and P < 0.01 respectively vs the induced fibrosis group), as was the average area of collagen in rats' liver, the concentrations of serum HA, LN, CIV, PCIII and liver tissue homogenate Hyp. The gene expression of alpha-SMA mRNA was considerably decreased in the treated animals, as was the protein espression of pp38 protein. CONCLUSIONS:
Oxymatrine is effective in reducing the production and deposition of collagen in the liver tissue of experimental rats in ways which relate to modulating the fibrogenic signal transduction via p38 MAPK signalling pathway.
