[Article in Russian]


EHF electromagnetic radiation under short-time action suppresses the cytotoxical activity of the natural killer cells from granulocyte fraction and peripheral blood of healthy volunteers; the observed effect is non-linear. Under the long-time irradiation of the natural killer cells from the mononuclear fraction of blood, the suppressing effect gets a practically linear character after the 20-30 minutes action. Under the long-time irradiation of peripheral blood the insignificant stimulation of natural killers was observed. It is assumed that the radiation applied can suppress the cytotoxic activity of the natural killers, breaking the normal metabolic pathway of phosphatidylinositphosphate.
