1 We examined the effects of haemoglobin (which inhibits the vascular responses to stimulation of soluble guanylate cyclase) and of M&B 22,948 (which selectively inhibits cyclic GMP phosphodiesterase) on the relaxation induced in rabbit aorta by the atrial natriuretic peptide, atriopeptin II (which stimulates particulate guanylate cyclase). 2 Pretreatment with M&B 22,948 (100 μM) produced a 2.3 fold potentiation of atriopeptin II‐induced relaxation of endothelium‐denuded rings of rabbit aorta. 3 Pretreatment with haemoglobin (10 μM) had no effect on the relaxation or the 10.9 fold increase in cyclic GMP content induced by atriopeptin II in endothelium‐denuded rings of rabbit aorta. 4 The potentiation by M&B 22,948 suggests a causal role for cyclic GMP in mediating atriopeptin II‐induced vasodilatation of rabbit aorta. 5 The inability of haemoglobin to block the atriopeptin II‐induced rise in cyclic GMP suggests that it does not block stimulation of particulate guanylate cyclase. Thus, it is unlikely that a ferrous haem‐containing receptor site is involved in the activation of the particulate form of guanylate cyclase as it is with soluble guanylate cyclase.
