title: [Study of physical properties of the apical membrane of enterocytes of rat small intestine under the effects of ionizing radiation].
abstract: The effect of X-ray radiation in doses of 1.0 and 3.0 Gy (1 day after irradiation) on physical properties of the apical membrane of rat small intestine enterocytes is studied. It is shown that the fluidity of the bulk lipids doesn't change but the fluidity of the boundary lipids increases after irradiation. The data on quenching of the tryptophane fluorescence by pyrene and magnesium ions indicates apparently the irradiation--induced protein aggregation in membrane.
