[Effect of normo- and hypobaric hypoxia on ultrastructure of the lung and myocardial tissue].
Priority of effect of oxygen concentration and/or atmospheric pressure changes on morphofunctional state of lung tissue and myocardium under exasperate influence on the organism, which lead to the development of different hypoxic states, was investigated. It was shown, that the intermittent hypoxia without barometric pressure lowering influence on ultrastructure of tissues less traumatically, then hypobaric hypoxia. Additional acute hypoxic influence and acute hemorrhage accompanied with less significant structural violations in lung tissue and myocardium of animals, which were adapted to hypobaric hypoxia. Stress exchanges were less considerable after normobaric hypoxic trainings.
