BACKGROUND
Pulmonary arterial hypertension (PAH) is a fatal disease characterized by increased pulmonary arteriolar resistance. Pulmonary vasoconstriction has been proved to play a significant role in PAH. We previously reported that Panax notoginseng saponins (PNS) might attenuate hypoxia and
Pulmonary arterial hypertension (PAH) is a disease of the small pulmonary arteries characterized by increased vascular resistance. Pulmonary vasoconstriction has been proven to play a pivotal role in PAH. We have previously hypothesized that Panax notoginseng saponins (PNS) might attenuate
