Abstract

In this study, the changes of arachidonic acid metabolites after an ischemia-reperfusion (I/R) period are investigated. The cyclooxygenase and lipoxygenase metabolites were found to be significantly increased after a 45 min period of ischemia followed by 5 min of reperfusion. Prostaglandin E(2) (PGE(2))- and leukotriene C-4 (LTC(4))-like activities did not change in the ischemic period, but they both increased after reperfusion. A cyclooxygenase inhibitor indomethacin and lipoxygenase inhibitor nordehydroguaretic acid (NDGA) decreased PGE(2)- and LTC(4)-like activities, respectively, while allopurinol and superoxide dismutase (SOD) decreased both activities.
