title: Time factor in PHA responsiveness of human blood lymphocytes after in vitro irradiation.
abstract: Human blood lymphocytes were irradiated in vitro prior to or following PHA-stimulation. Radiation dose-response profiles indicate that PHA-pretreatment of cells has no protective effect. PHA-reactivity of the cells decreases with increase of the time interval between irradiation and subsequent PHA stimulation.
