title: Urate causes the human polymorphonuclear leukocyte to secrete superoxide.
abstract: The human polymorphonuclear leukocyte generates O2-. and H2O2 when it is treated with uric acid. A transition metal catalyzed reaction between O2-. and H2O2 can give the hydroxyl radical and myeloperoxidase forms hypochlorous acid from H2O2 and chloride. Therefore, the uric acid-induced secretion of oxidants may be responsible for a large part of the inflammation associated with gout.
