Vasodilation by hyperpolarization: beyond NO.
Clinical assessment of human vascular endothelial function in vivo involves use of specific antagonists such as L-N monomethyl arginine (L-NMMA) and cyclooxygenase inhibition to establish the contribution of NO and prostaglandins, respectively, to either resting vascular tone, agonist-stimulated vasodilation, or physiological and metabolic vasodilation.1–4 Even after complete inhibition of NO a...
متن کاملHeme oxygenase-mediated vasodilation involves vascular smooth muscle cell hyperpolarization.
Chronic hypoxia is associated with both blunted agonist-induced and myogenic vascular reactivity and is possibly due to an enhanced production of heme oxygenase (HO)-derived carbon monoxide (CO). However, the mechanism of endogenous CO-meditated vasodilation remains unclear. Isolated pressurized mesenteric arterioles from chronically hypoxic rats were administered the HO substrate heme-l-lysina...
متن کاملBradykinin-induced vasodilation of human forearm resistance vessels is primarily mediated by endothelium-dependent hyperpolarization.
Bradykinin (BK) stimulates endothelial cells to release a number of relaxing factors, such as NO, prostanoids (PGs), and an endothelium-derived hyperpolarizing factor (EDHF). However, the contributions of NO, PG, and EDHF in the vascular relaxation to BK vary with species and anatomic origin of blood vessels used. Therefore, the present study was designed to investigate the contributions of NO,...

متن کاملAdenosine instead of supranormal potassium in cardioplegic solution preserves endothelium-derived hyperpolarization factor-dependent vasodilation.
OBJECTIVE We have recently shown that adenosine instead of supranormal potassium in cold crystalloid cardioplegia improves cardioprotection. Studies indicate that hyperkalemia has unfavorable effects on vascular endothelial function. Three pathways have been identified as major vasodilatory pathways: the nitric oxide (NO) pathway, the cyclooxygenase (COX) pathway, and the endothelium-derived hy...
