[Study of changes in the surface of irradiated thymocytes using a method of separating cells in a 2-phase...

The coefficient of cell distribution in a charged biphase water-polymeric system "polyethyleneglycol-dextran" decreased 60 min after irradiation of rat thymus lymphocytes with doses of 1 to 8 Gy. This dose-dependent effect was mainly related to radiosensitive thymocytes of a low fraction of density gradient; it disappeared with the uncharged system and was probably connected with the reduction in the negative electric charge of the irradiated cell surface.
