[Relation between erythrocyte photodamage and the intensity of ultraviolet radiation]

Photoperoxidation of lipids (PPOL) in erythrocytes membranes and photohemolysis are essentially weakened with an increase of UV - irradiation intensity at constant irradiation dose. The initial part of the relationship between PPOL product concentration or rate of hemolysis and irradiation intensity is of a linear pattern. This is explained by the fact that the breakage of the chains of lipid free radical photooxidation on endogenous alpha-tocopherol is more effective than disproportionation of peroxide free radicals.
