Dihydroartemisinin attenuates pulmonary inflammation and fibrosis in rats by suppressing JAK2/STAT3 signaling
Figure 1. DHA attenuates early alveolar inflammation in a bleomycin-induced rat pulmonary fibrosis model. At 7 days after bleomycin intratracheal administration, with or without DHA treatment, the rats were sacrificed, and their lungs and blood were removed. (A) H&E staining was used to detect the lung histopathological changes and (B) Lung inflammation was scored (n = 6). *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; NS: not statistically significant.
