To investigate the effect of changes in intracellular H+ concentration [( H+]i) on pulmonary arterial tone, isolated canine intrapulmonary arteries were exposed to NH4Cl (4-120 mM). Above 4 mM, NH4Cl caused contraction. When induced by less than or equal to 30 mM, contraction was not endothelium dependent and was unaffected by calcium-free medium or by(More)
