Figure 6

The expression of IFN-γ protein and mRNA in bleomycin-induced pulmonary fibrosis rats treated with Yangqing Kangxian formula, prednisone, or pirfenidone. (a) Immunohistochemical image of IFN-γ, magnification 400x, scale bar: 50 μm; (b) IFN-γ protein; (c) IFN-γ mRNA. BLM: bleomycin; YKF: Yangqing Kangxian formula; PD: prednisone; PF: pirfenidone. Values represented as mean ± SEM. AAP < 0.01 and AP < 0.05, versus BLM group. BBP < 0.01 and BP < 0.05, versus BLM + YKF group, CCP < 0.01 and CP < 0.05, versus BLM + PD group, and DDP < 0.01 and DP < 0.05, versus BLM + PF group. The red arrows point to the positive expression area.
