Effects of Tan IIA on oxidative stress-associated factors in lung tissue. (A) Representative images of immunohistochemical staining for COX-2 protein in lung tissue samples, scale bars=20 μm. (B) COX-2 protein expression in lung tissue specimens determined by western blot analysis. (C) PGE2 expression and (D) MDA concentration in lung tissues. Results are expressed as the mean ± standard deviation, n=3 per group. ###P<0.001, versus the control group; †††P<0.001, versus the Tan IIA group; *P<0.05 and ***P<0.001 versus the BLM group. COX-2, cyclooxygenase-2, PGE2, prostaglandin E2; MDA, malondialdehyde; Tan IIA, Tanshinone IIA; BLM, bleomycin.
