摘要: ATP dose dependently stimulated the formation and release of nitric oxide (NO) from perfused rabbit aorta. L-Canavanine, an inhibitor various L-arginine-utilizing enzymes, abolished basal ATP-induced NO release. increased accumulation presumably NO-derived NO2- in medium primary cultures bovine aortic endothelial cells. 15NO, 15NO2- 15NO3- was found when L-[guanido-15N2]arginine added to culture medium. We conclude that terminal guanidino nitrogens L-arginine are physiological precursors endothelium-derived NO.
