[Loss of specific membrane receptors during the interphase death of thymus cells]

Thymic cells of the white rats were incubated in medium 199 with isologous sera. A dose-dependent decrease in number of membrane receptors to autologous red blood cells, alongside with nuclear pyknosis and maesophage adhesion, were noted during the first 6 hours after gamma-irradiation at the doses up to 8 Gy. A decline of rosette-forming ability preceded the process of massive nuclear pyknosis. A conclusion is made on a possible interrelation between the membrane and nuclear pathology after radiation treatment.
