The lung tissues were collected on Day 7. (A) The histopathologic examination was determined by H&E staining. (×200, Scale bar = 100 μm). (B) The comparisons of the inflammation score values in each group. n = 4–7. (C) W/D ratio, n = 5–9. (D) The activity of MPO in lung homogenate, n = 3–6. Bars: mean ±SD. *P<0.05, **P<0.01 vs control group. #P<0.05, ##P<0.01 vs BLM group.
