Figure 1: Effects of Sal B and perindopril (PER) on DMN-induced rat hepatic fibrosis. (a) Representative photomicrographs of Sirius red staining for rat liver. (b) western blot analysis of Col-I in rat liver. Rat liver protein was extracted and the samples were electrophoresed and analyzed by Western blot with Col-I antibody. ((c) and (d)) Quantities for densitometric analysis of Col-I and α-SMA. Each bar represents the means ± S.D. of three rats assayed in triplicate. (e) Hydroxyproline content in normal and DMN-induced rats livers. ** versus normal; ## versus model.
