Abstract: PRODUCTION of reactive oxygen species is an important mechanism of cold ischemia-reperfusion (CIR) injury.1,2 Among different activated oxygen species, hydrogen peroxide (H2O2) plays a significant role.3,4 However, the precise mechanism of H2O2-mediated cellular injury and the specific cellular sites of H2O2 attack are not well defined. Recent studies suggest that mitochondria are one of the main targets of early reperfusion injury in endothelial cells.5 Thus, the purpose of this study was to evaluate short-term effects of H2O2 on the mitochondrial respiratory chain and mitochondrial membrane potential (MMP) in endothelial cells.
