Nitrite anions comprise the largest vascular storage pool of nitric oxide (NO), provided that physiological mechanisms exist to reduce nitrite to NO. We evaluated the vasodilator properties and mechanisms for bioactivation of nitrite in the human forearm. Nitrite infusions of 36 and 0.36 μmol/min into the forearm brachial artery resulted in supra- and(More)
Our previous results run counter to the hypothesis that S-nitrosohemoglobin (SNO-Hb) serves as an in vivo reservoir for NO from which NO release is allosterically linked to oxygen release. We show here that SNO-Hb undergoes reductive decomposition in erythrocytes, whereas it is stable in purified solutions and in erythrocyte lysates treated with an oxidant(More)
