Dzheldubayeva E. The antinociceptive effect of low intensity, ultra-high frequency electromagnetic field

This dissertation addresses the issue of conformity to natural laws of antinociceptive effect of exposure to low intensity, ultra-high frequency electromagnetic radiation (UHF EMF) (wave length 7.1cm, density of power flow 0,1mW/cm2). Analysis of the collected experimental data, that previous both single and course expose to low intensity UHF EMF turned to result in significant antinociceptive effect on pain stress of different etiology (tonic, visceral, sharp pain), so to prove certain universal analgetic influence of UHF EMF on an organism. The antinociceptive action of UHF EMF influence the following effects: decreased duration of pain reactions; growth of pain sensitivity threshold, pain endurance level and non-pain behavior duration; restoration of correlation and cluster interrelation between different behaviour forms; modification pain sensitivity rhythmical processes in rats within high-frequency, ultra- and infradian ranges. Opioid peptides, serotonin, melatonin, dopamine - and noradrenergicsystems take significant part in the mechanisms of analgetic effect of millimeter irradiation.
