Peculiarities of superficial architectonics of peripheral blood erythrocytes in children irradiated in utero at the contaminated areas

Cytology and Genetics 2006, v 40, number 6, 40-43

In the dynamics of the Chernobyl postaccidental period the electron microscopy examinations of the superficial architectonics of peripheral blood erythrocytes have been performed in the children irradiated during the uterine development and at the following stages of the ontogenesis. The expressed morphological reorganization of the erythrocyte populations was revealed in the children irradiated in utero at all the stages of investigation: the number of diskocytes decreased and the number of transitory, predhemolytic and degenerative forms increased in comparison with the control. The disorders in the superficial relief and in the form of blood erythrocytes indicative of the disorganization and transformation of erythrocytes in the children irradiated in utero stipulate their functional inferiority.
