Makhonina M. Biological action of electromagnetic fields of extremely high frequency in the conditions of opioid peptide receptors blocking

The thesis is devoted to study of biological action of electromagnetic fields of extremely high frequency (?=7,1, mm, power flow density 0,1 mW/sm2) isolated and combined with experimentally envoked stress reaction (hypokinesia) in the conditions of opioid peptide system disabling, which is the one of the main stress-limiting organism systems, by injection of naloxone that is an antagonist of all sub-types of opioid peptide receptors. Obtaind results are an evidence that one of the mechanisms of biological action of low-intensity emission of millimeter range is an increase of functional activity of opioid peptide system which is a remedy of effective prophylaxis and correction of stress-reaction development. It is realized, firstly, by means of activity limitation of sympathoadrenal system through depression of the processes of catecholamine release and reception, secondly, by means of an increase of nonspecific resistance and immunological reactivity, thirdly, by means of stimulation of generation andrelease of serotonin and melatonin, that is, potentiation of activity of other stress-limiting organism systems. Key words: low intensity EMF of EHF, opioid peptides, naloxone, morphometric analysis, microspectral luminescent analysis.
