title: [Normal killer function in CBA mice as affected by long-term intake of tritium oxide].
abstract: A study was made of the cytotoxic function of normal killers of CBA mice during long-term administration of tritium oxide in potable water (a cumulative absorbed dose of 8.7 Gy, dose-rate, 4.5 Gy/day) and at different times after termination of the radionuclide injection. A mean decrease of 20-30% in the lytic effect of the effectors from spleen of the experimental mice on cell-targets of K-562 human erythroleukosis was demonstrated by a 17-19-hour test with 51Cr. At later times after termination of action of tritium oxide, the cytotoxic effect of normal killers increased by 1.8 times as compared to intact controls of the same age.
