Abstract :
The paper presents the results of investigation of changes in structure and functional state of rat erythrocytes under effect of low intensity UV laser radiation (12plusmn2 mW, lambda 337.1 nm). As indicators of erythrocyte the parameters of acid hemolysis - rate, intensity, and content of products of erythrocyte membrane lipids peroxidation. It was found that the laser effect consists in intensification of processes of cell modification at the level of interaction with lipid bilayer of erythrocyte membrane. It results in decrease of erythrocyte resistance to effects of hemolytic factors. Combined effect of laser and diabetes amplifies the effect of laser at the level of the first stage of membrane modification at the way of lipid peroxidation.
