Popis: On days 1 and 4 after fractionated irradiation of rats with dose of 0.75 Gy changes in thymocyte and lymphocyte plasma membrane structures were studied. Structural parameters of fluorescence probe auramin binding, viscosity of free lipids and lipids bound with integral proteins as well as structural changes of membrane protein structure were determined. It was shown that after exposure to low doses the changes in membrane protein structures occurred both in thymocytes and lymphocytes. The changes in viscosity of membrane lipids and patterns of auramin binding were more pronounced in lymphocytes than in thymocytes. It is suggested that radiosensitivity of lymphocytes is higher than that of thymocytes.
