Treatment of pig serum-induced rat liver fibrosis with Boschniakia rossica, oxymatrine and interferon-α

Figure 2 Expression of TGF-β1 in liver tissue. A: RT-PCR products of TGF-β1 mRNA in liver tissue resolved on 1.0% agarose gel (M: markers;1: Control; 2: Model; 3: BR; 4: OM; 5: IFN-α); B: Results of model group rat liver specimens stained with IHC. Lots of α-SMA positive cells, hepatic cord lined up in disorder and fibrosis septum could be seen; C-F: Liver cells stained with IHC (×200) in control, BR, OM and IFN-alpha groups respectively.
