Preventive effect of Qianggan-Rongxian Decoction on rat liver fibrosis

Figure 1 Light microscopy showing normal liver tissue in the control group (HE staining, × 100) (A), liver fibrosis tissue and formation of more fibrous tissue as well as a large amount of inflammatory cells soaked in intralobules and interlobules in model group (van Gieson staining, × 100) (B), and liver fibrosis tissue in Qianggan-Rongxian Decoction treatment group (C). The pathological change in liver was rather milder compared with the model group (van Gieson staining, × 100).
