Figure 1.Ato improved the lung function of PAH rats. (A) Pathological changes of lung tissues after treatment with MCT and Ato; (B) mPAP of rats in different groups was measured at different time points; (C) RVHI of rats in different groups was measured at different time points; (D) WT was measured at different time points after treatment with MCT and Ato; (E) WA was measured at different time points after treatment with MCT and Ato. (*P<0.05, compared with control group, #P<0.05, compared with group PAH). Ten rats were used in each group.
