Influence of a mixture of chemical protectors on the lymphoid regeneration of bone marrow and thymus in irradiated mice.

In mouse, the administration of chemical protectors before an irradiation induces a more rapid bone marrow regeneration and an increased lymphoid rebound. In the thymus, the late atrophy is reduced. Separately administrated, the protectors decrease greatly the thymocytes number but have no effect on the marrow population.
