Histopathological examination and immunohistochemical staining of ZJW-treated livers in an orthotopic intrahepatic xenograft mouse model. Mice were injected with HepG2/NF-κB/Luc cells. Three days later, mice were orally given with 200 mg/kg ZJW or PBS for consecutive 7 d. Livers were then collected for histopathological examination (a) and immunohistochemical staining with anti-luciferase antibody (b). Photos are representative images (n = 6). Magnification 400 ×
