Protective and damaging role of electromagnetic influences on biomembranes

Abstract

The paper presents the results of studies of the effect of an alternating low-power electromagnetic field and light irradiation with monochromatic light from a laser source on the state of biological membranes. It was shown that the effect of these factors on the erythrocyte membrane causes a different effect and
affects its resistance differently, which is reflected in the change in the erythrogram of acid hemolysis in the experiment. It has been established that the action of an ultrahigh-frequency electromagnetic field leads to a decrease in the resistance of erythrocytes and an increase in the rate of lysis of red cells. Laser
irradiation with a low-power helium-neon laser at low exposure increases the resistance of red blood cells to acid hemolysis. Increasing exposure reduces the effect noted. With simultaneous processing of blood samples by UHF (ultra high frequency electromagnetic fields) source and laser light, a significant decrease
in the negative effect of the UHF field on the resistance of biomembranes is noted. Possible mechanisms of marked biological effects are discussed.
