Abstract

Free radicals species have been implicated as important agents involved in myocardium ischemia and reperfusion injuries (Mac Cord, 1985). The major cytotoxic effect of oxygen-derivated free radicals may be peroxidation of lipid components of cellular membranes which may be an important process for cell damage during myocardial infarction. In this study, Electron Paramagnetic Resonance Spectroscopy (EPR) was used to directly mesure free radical generation in isolated perfused rat hearts (Maupoil and Rochette, 1988). We also investigated the formation of thiobarbituric acid reactants as an index of lipid peroxidation. The effect of TMZ in the postischemic heart was determined.
