Abstract:

The role of the intact thymus in recovery of the immune response following a sublethal dose of X radiation was studied. Groups of adult LAF1 mice were exposed to 500 rad of X rays and some of these animals, appropriately lead-shielded, then received an additional 500, 1000, or 2000 rad to the thymic area through a 1.2 cm diameter shield opening. Three criteria of immunological response were employed 1 numbers of Jerne antibody plaque-forming cells PFC in the spleen 2 concentration of antigen-reactive cells ARC 3 rejection time of skin homografts.
