Effect of Xuebijing on the activation of NF-κB65 in paraquat-induced lung tissue using immunohistochemical staining (×200). A: Representative immunohistochemical-stained graphs of NF-κB65-positive expression (a: control group, b: paraquat group, c: Xuebijing + paraquat group, d: dexamethasone + paraquat group). B: Statistical analysis of NF-κB65-positive expression. Data are expressed as mean ± SEM. **P < 0.05 compared with control group; ^# P < 0.05 compared with paraquat group; P > 0.05 Xuebijing + paraquat group compared with dexamethasone + paraquat group.
