title: [Effect of the hyperbaric oxygenation of animals and man on mitochondrial function in their tissues (based on EPR study data)].
abstract: The ration of differential intensities of EPR signal of free endogenous radicals of semiquinone type and iron-sulfur proteins recorded at the temperature of liquid nitrogen in tissues (R index) is proposed as a criterion for estimation of changes in the functional state of mitochondria in human and animal tissues treated with hyperbaric oxygenation (HBO). The increase in R value was observed in hearts of intact mice and rabbits treated with HBO in near-toxic doses. This indicates a shift in mitochondria redox state towards oxidation. The above effect was not observed in mitochondria from intact zone of myocardium in animals with experimental infarction, and the numbers of mitochondria in the tissue increased after HBO. HBO treatment of women with pathological pregnancy leads to the decrease in R value for placental mitochondria.
