[Dinitrosyl complexes of iron with glutathione in the rat myocardial tissue during regional ischemia and postischemic reperfusion].

The injection of dinitrosyliron iron complexes with glutathione at the onset of 40-min rat regional myocardial ischemia was shown to exert a clear cardioprotective action by decreasing the infarct size and suppressing the cardiac rhythm disturbance. After the introduction of the preparation, its effective accumulation with protein thiol-containing ligands in the myocardial tissue was registered be the EPR method. It was also found that, as a result of postischemic reperfusion, the rate of the decrease in the content of these complexes in the ischemic area increases, which demonstrates the effective scavenging of short-lived reactive oxygen species by molecules of dinitrosyl iron complexes.
