  • Title: [Effect of ionizing radiation and Fe2+-induced peroxidation on the lipid phase of erythrocyte membrane preparations].
    Author: Fomenko BS, Agafonova TA.
    Journal: Radiobiologiia; 1987; 27(1):41-5. PubMed ID: 3823382.
    Abstract:
    The fluorescent probes, perilene and diphenyl hexatriene, were used to study changes in the lipid phase of erythrocytic ghosts induced by ionizing radiation (100-1000 Gy) and lipid peroxidation initiated by Fe2+ (5-100 microM). Both of the factors were shown to bring about similar changes in the membrane, that is, an increase in the viscosity of the probe localization sites and a decrease in diphenyl hexatriene fluorescence intensity. During the postirradiation incubation of the exposed membranes they were additionally damaged whereas upon peroxidation, most of the changes occurred after 15-min incubation with Fe2+.
