From: Fuzheng Huayu recipe alleviates hepatic fibrosis via inhibiting TNF-α induced hepatocyte apoptosis

Figure 2

Fuzheng Huayu recipe (FZHY) and N-acetylcysteine (NAC) improves hepatic fibrosis. Mice were respectively treated orally with FZHY (4.0 g/kg) or NAC (0.1 g/kg) daily for 3 d before CCl4 treatment. Then, mice were injected at 8 weeks of age with 100% CCl4 3 ml/kg body weight for the first time, then 50% CCl4 /olive oil 3 ml/kg body weight, two times per week for 8 weeks to develop hepatic fibrosis (A). Liver sections were subjected to either hematoxylin-eosin staining to detect inflammatory cell infiltration and necrosis (B, × 100) or to the terminal deoxynucleotidyl transferase-mediated dUTP nick-end labeling (TUNEL) assay to detect cell apoptosis (C, × 200) or to immunohistochemical staining for α-SMA for detection of activated hepatic stellate cells (HSCs) (D, × 200) or to Sirius Red staining for detection collagen deposition (E, × 200). (F) Serum ALT and AST levels and Alb content in the four groups (Control, n = 10; CCl4 treated, n = 11; FZHY treated, n = 11; NAC treated, n = 12). (G) Hepatic Hyp content was determined using Jamall’s method. The Hyp content was increased significantly in CCl4 treated group compared with the control group. FZHY or NAC treatment significantly decreased liver Hyp content. ** P < 0.01 vs. control group; ## P < 0.01 vs. model.
