A-740003 ameliorated pulmonary angioproliferation and the development of severe PH. a Haematoxylin and eosin and IHC staining of b alpha-actin with α-SMA antibody. c Ratios of vascular medial thickness (i.e., smooth muscle thickness) to the outer diameter (total vessel wall thickness) of the small pulmonary arteries (diameter 50–100 μm) in PH and normal rats. d Vascular occlusion score of the small pulmonary arteries (diameter 20–30 μm) in PH and normal rats. Data are the mean ± SD, n = 6. *p < 0.05, **p < 0.01 compared with the sham group; †p < 0.05 compared with the P/MCT vehicle group
