The changes of the membrane-dependent properties of the rabbit erythrocytes after low intensity submillimeter (SMM), green and ultraviolet (UV) laser irradiation with wavelength of 70.6 pm, 532 nm and 337 nm, respectively, were investigated. Parameters of acid hemolysis kinetics: a rate constant and content of lipid peroxidation products in erythrocyte membrane were as an indicator of the erythrocyte state. Obtained data allow one to assume that laser radiation of different wavelength is accepted by different cellular objects: water molecules (CMM), hemoglobin (green spectral region) and conjugated double bonds in unsaturated fatty acids of biomembranes (UV).
