TCST attenuated pulmonary vascular remodelling induced by MCT. a Representative H & E stained pulmonary artery sections from each group of rats (scale bar = 25 μm). b Representative Elastin-Van Gieson (EVG) staining images of the pulmonary artery (scale bar = 25 μm). c Representative immunohistochemical staining images of α-SMA in the pulmonary artery (scale bar = 25 μm). d Representative photomicrographs of CD3 positive cells in the lung (red arrows indicate positive cells, scale bar = 25 μm). e The ratio of wall thickness (WT)/vessel radius in the pulmonary arteries. f Quantification of CD3 positive cells in each group. g, h TCST reduced the NE concentrations in lung homogenate and TH expression in the pulmonary artery tissues, which were significantly increased in the MCT rats. **P < 0.01 vs. control group; #P < 0.01 vs. MCT group; &P < 0.01 vs. MCT + sham group
