Sildenafil and an early stage of chronic hypoxia-induced pulmonary hypertension in newborn piglets.
Devising therapies that might prevent the onset or progression of pulmonary hypertension in newborns has received little attention. Our major objective was to determine whether sildenafil, a selective phosphodiesterase inhibitor, prevents the development of an early stage of chronic hypoxia-induced pulmonary hypertension in newborn pigs. Another objective was to determine whether sildenafil cau...
متن کاملL-Citrulline ameliorates chronic hypoxia-induced pulmonary hypertension in newborn piglets.
Newborn piglets develop pulmonary hypertension and have diminished pulmonary vascular nitric oxide (NO) production when exposed to chronic hypoxia. NO is produced by endothelial NO synthase (eNOS) in the pulmonary vascular endothelium using l-arginine as a substrate and producing l-citrulline as a byproduct. l-Citrulline is metabolized to l-arginine by two enzymes that are colocated with eNOS i...
متن کاملEffect of a phosphodiesterase 5 inhibitor on pulmonary and cerebral arteries of newborn piglets with chronic hypoxia-induced pulmonary hypertension.
BACKGROUND The use of phosphodiesterase 5 (PDE5) inhibitors to treat newborns with pulmonary hypertension is increasing. The effect of PDE5 inhibitors on the neonatal cerebral circulation remains unknown. The neonatal piglet model of chronic hypoxia-induced pulmonary hypertension allows the study of the effects of PDE5 inhibitors on both the pulmonary and cerebral circulations. OBJECTIVES To ...
متن کاملStatins and Pulmonary Hypertension in Chronic Obstructive Lung Disease
Chronic obstructive lung disease (COPD) is a chronic multisystem disease with a considerable burden. One of its most common complications is pulmonary artery hypertension (PAH). It has been demonstrated that the development of PAH is correlated with decreased quality of life and survival. Different medications have been proposed for the treatment of PAH, among which one can name statins. Howeve...
متن کاملProtein complex formation with heat shock protein 90 in chronic hypoxia-induced pulmonary hypertension in newborn piglets.
Aberrant interactions between heat shock protein (Hsp)90 and its client proteins could contribute to pulmonary hypertension. We tested the hypotheses that 1) the interaction between Hsp90 and its known client protein, endothelial nitric oxide synthase (eNOS), is impaired in pulmonary resistance arteries (PRAs) from piglets with pulmonary hypertension caused by exposure to 3 or 10 days of hypoxi...
