The ability of peripheral blood lymphocytes to repair DNA and the survival of rats

Individual and group differences were revealed in the capacity of rat peripheral blood lymphocytes of DNA repair in response to the DNA damaging test-effect of irradiation in vitro. The survival rate of rats irradiated with a dose inducing 50-per cent death was in a definite relationship with the repair capacity of blood lymphocyte DNA in each animal individual prior to irradiation.
