title: [The action of short-range low-intensity infrared laser irradiation on the functional and metabolic parameters of the isolated rat myocardium in hypoxia].
abstract: It was found that infrared laser radiation (IRL) reduces the sparing action of acute hypoxia on ventricular transport function of low-resistant animals and accelerates the recovery of the function during the post-hypoxia period. The effect was caused by the IRL affecting directly the speed of perfusion through the myocardium and thus the latter's breathing rate. The protective effect of the IRL was practically absent in highly resistant animals, which may be indicative of the existence of basic differences in the regulatory systems which is responsible for local vasodilation and supply of oxygen to cells, and which participates in the formation of resistance of cardiomyocytes to oxygen shortage.
