ABSTRACT

The paper describes the action of low-intensity laser radiation (LILR) and high-intensity one (HILR) on biological tissues. LILR produces its action on cells by changing the membranous formations-receptors and ion channels. At cardiac surgery, HILR stimulates uncontractile myocardial elements, by inducing the secretion of biologically active substances and the activation of enzyme systems that ensure the implementation of neoangiogenesis in the ischemic myocardium.
