Abstract. †† Researches
†of extremely high frequencies electromagnetic radiation† influence on ††model phosphatidylcholine
liposomes and their aqueous environment are carried out. It is shown by NMR 31–-spectroscopy
and PMR-relaxation, that irradiation of samples leads to the reduction of
phosphorus-containing hydrophilic heads and to distortion of lipid molecules bilayer
†packaging in model biomembrane. It is found that in the manifestation of appropriate
effects significant role belongs to lipids water environment, and under
irradiation occurs the rebuilding of aquaspheres around coordinating centres of
phospholipids, that at cellular level contributes to the harmonization of †organism
Keywords. Liposomes, electromagnetic radiation in the
millimeter range, spectroscopy, nuclear magnetic resonance, conformation.
