1 Bradykinin-induced, N omega-nitro-L-arginine-insensitive endothelium-dependent relaxation of porcine coronary arteries is not mediated by bioassayable relaxing substances. Nitroarginine kininogen 1 Homo sapiens
2 The effect of the arginine analogue, N omega-nitro-L-arginine (L-NNA) was studied on bradykinin-induced relaxation in porcine coronary arteries. Nitroarginine kininogen 1 Homo sapiens
3 The effect of the arginine analogue, N omega-nitro-L-arginine (L-NNA) was studied on bradykinin-induced relaxation in porcine coronary arteries. Nitroarginine kininogen 1 Homo sapiens
4 In contrast to the findings in organ chamber experiments, bradykinin-induced release of endothelium-derived relaxing factor(s) (EDRFs) was abolished after 45 min of treatment of perfused porcine coronary artery segments with L-NNA (10(-4) M) in a superfusion bioassay system. Nitroarginine kininogen 1 Homo sapiens
5 These results show that, in addition to the release of nitric oxide, endothelium-dependent relaxation of porcine coronary arteries to bradykinin involves an alternative mechanism(s), which accounts for the relaxation in the presence of L-NNA. Nitroarginine kininogen 1 Homo sapiens
