On the hypoxic pulmonary hypertension (HPH) animal model, the plasma H 2S concentration, the gene expression and the activity (CSE) were decreased in lung tissues In L -NAME induced hypertension and spontaneous hypertension rats (SHR) models, the plasma H 2S concentration, vascular CSE activity and mRNA expression were obviously decreased. When H 2S was exogenously supplied, systolic pressure obviously decrease. These studies suggested that CSE/H 2S pathway participated in the pathophysiological development of hypertension.
