Figure 4. Representative images of (A) p-JAK2, (B) STAT3, and (C) p-STAT3 protein levels in lung tissue detected by IHC. Mean IOD of (D) p-JAK2, (E) STAT3, and (F) p-STAT3 protein by IHC staining. Data are expressed as the means ± standard error. *P < 0.05, **P < 0.001. Abbreviations: BLM: bleomycin; DHA-1: dihydroartemisinin 25 mg/kg/d; DHA-2: dihydroartemisinin 50 mg/kg/d; DHA-3: dihydroartemisinin 100 mg/kg/d; IHC: immunohistochemistry; IOD: integrated optical density; NS: not statistically significant.
