Abstract
During last years considerable interest has been devoted to understand the role of oxygen radicals in the ischemia induced cell injury associated with reperfusion. In the brain and in others tissues, free radicals play a role as modulators of vascular tone as well as a cytotoxic role as part of the ischemia associated pathology. This review discusses methods for free radical detection in brain and in other tissues, mechanisms of radical production in the course of the ischemia reperfusion process, and the efficacy of potential antioxidant agents in post ischemia therapy, especially with respect to allopurinol, an inhibitor of xanthine oxidase, and the role of taurine and its derivatives as antioxidants in different organs including the brain.
