dc.description.abstractPulmonary arterial hypertension is caused by complex structural and functional changes in the endothelial and smooth muscle cells of pulmonary arteries. Hydrogen sulfide (H2S), a gasotransmitter, can potentially treat pulmonary hypertension by relaxing the pulmonary arteries and decreasing bronchial pressure. Although the role of H2S in systemic circulation has been examined, the H2S levels in pulmonary arteries, the role of H2S in endothelium-dependent vasorelaxation and the L-cysteine/H2S pathway in monocrotaline-induced pulmonary arterial hypertension have not been investigated. The rats were divided into control, monocrotaline, monocrotaline + Na2S, and Na2S groups. The right ventricular pressure and hypertrophy were evaluated. KCl, acetylcholine, and L-cysteine responses were obtained in the main pulmonary arteries by wire myograph. H2S levels were measured in pulmonary arteries and lungs by methylene blue assay. Right ventricular pressure and hypertrophy were increased by monocrotaline and ameliorated by Na2S. The KCl-induced contractions and relaxing responses to acetylcholine and L-cysteine in pulmonary arteries and H2S production in the lungs and pulmonary arteries were significantly attenuated in the monocrotaline group and augmented in the monocrotaline + Na2S group. These findings suggest that H2S levels were reduced, and L-cysteine-induced and endothelium-dependent relaxations were impaired in the pulmonary arteries in monocrotaline-induced pulmonary arterial hypertension. The H2S donor, Na2S, prevented endothelial dysfunction and increased pulmonary artery pressure and hypertrophy. Also, Na2S enhanced the L-cysteine-mediated responses and restored the diminished H2S levels in pulmonary arteries and the lungs. The treatments targeting H2S might be beneficial for promoting vascular alterations, i.e. endothelial dysfunction and impaired H2S-mediated relaxation in pulmonary arterial hypertension.en_US
