Effects of HQD on hepatocyte apoptosis (A), caspase-3 and HGF expression (B) in DMN-induced liver fibrosis in rats. Hepatic cryosections were stained with TUNEL (green) and hepatocytes paraffin antigen (Heppar, red). TUNEL (green) located in or near Heppar (red) means hepatocyte apoptosis. The arrows with blue color indicate apoptotic hepatocytes, the arrows with white color indicate non-hepatocyte apoptosis. (Original magnification × 400).
