Icariin Attenuates Monocrotaline-Induced Pulmonary Arterial Hypertension via the Inhibition of TGF-β1/Smads Pathway in Rats

Figure 2

Icariin suppresses pulmonary small artery remodeling. Representative photomicrograph of pulmonary small artery remodeling indicated by HE staining (a) and WT% was used to measure the wall thickness in pulmonary small artery (b) (scan bar = 50 µm, 400×). ρ < 0.05, ρ < 0.01, ns = no significant. N = 6/group.
