ABSTRACT: The aim of the research was to study the influence of coherent
and incoherent (noise) electromagnetic radiation (EMR) of mm-range on structural-functional
properties of erythrocyte membranes under the total radiation exposure
of animals.
The increase of lipid peroxidation product (LPP) level and the change
of the quantitative content of phospholipid (PL) fractions of erythrocyte
membrane were detected. The changes of some functional properties were
revealed as well: the increase of the outflow of K+-ions from erythrocytes
and the membrane potential of these cells. These changes are more significantly
prominent under exposure to incoherent electromagnetic waves (EMW).
The disturbance of some indices of structural-functional state of biomembranes
was investigated in erythrocytes under exposure to EMR of mm-range, alteration
was revealed due to the change of physical and chemical properties of their
lipid component.
KEY WORDS: Mm-radiation, erythrocyte membranes, membrane potential,
