[Lymphocyte cytotoxic activity in radiation lesions]

A study is presented of the effect of roentgen radiation on the cytotoxic activity and spontaneous rosette formation of guinea pig lymphocytes. The animals were irradiated by roentgen rays in 2.58 mC/kg and 180.60 mC/kg. Results indicate that 24 hours after irradiation there was a significant reduction of the cytotoxic activity (38% as compared with the control) and doses-dependent reduction of rosette formation cells.
