The NO-mediated component of acetylcholine-induced relaxation was reduced in these rats. At the same time, arterial relaxation mediated by endothelium-dependent hyperpolarization was increased. Endothelium-independent relaxation of mesenteric arteries to sodium nitroprusside in rats with metabolic syndrome was the same as in the arteries of control rats.
