title: [Effect of a series of brief cycles of ischemia and reperfusion on free radical centers of isolated rat myocardial tissue].
abstract: Free-radical species of rat isolated hearts, perfused by Langendorf mode before and after the ischemic preconditioning, have been studied by the ESR method. It has been obtained that the preconditioning results in increasing of ubisemiquinone concentration in myocardium, which cause the changes in spectral and relaxation characteristics of the ESR signals.
