The immunodepressive effect of transcerebral laser radiation

Effects of opioid peptides on the development of ischemic cardiac arrhythmias under conditions of partial sympathetic denervation and laser irradiation

“…Proceeding from published data on LI-induced activation of the endogenous opioid system, it can be suggested that long-term LI depletes the sympathetic stores of opioid peptides inhibiting the release of noradrenaline [2,7,8,10]. Under conditions of partial denervation of the myocardium and hyperactivation of the remaining sympathetic innervation, LI can produce temporary local depletion of endogenous opioids, which aggravates occlusion-induced ischemia and facilitates the development of cardiac arrhythmias.…”
