ABSTRACT
The objective of the present research was to study transformations of various physiological NO forms in an isolated rat heart, perfused with the medium, containing dinitrosyl iron complexes with glutathione ligand (DNIC-GH). We showed that such aerobic perfusion resulted in accumulation of mostly diamagnetic NO physiological forms (S-nitrosothiols) in myocardial tissue. They were transformed into protein-bound mononuclear dinitrosyl iron complexes during subsequent total ischemia. Meantime, DNIC-GH injection on the onset of ischemia resulted in the changes in the state of mitochondrial respiratory state, characterized by the increase in myocardial concentration of flavosemiquinones.
