[Connection of functional characteristics and ultrastructure of the lung and myocardium in hypoxia and srtess].

The estimation of changes in breathing, circulation, gas exchange, lipid peroxidation, which can be connected with or determined by morphofunctional state of lung tissue and myocardium in rats under acute hypoxic hypoxia, acute dose hemorrhage and immobilization stress were made. Such approach is important not only from theoretical point of view, for the elucidation and definition of mechanisms which are responsible for function of oxygen-transport systems under unfavorable influences on the organism, but present particularly practical interest. The exposure of correlation between structure and function in investigated organs may permit to forecast the availability of some ultrastructural violations under ventilation or circulation changes in the organism.
