[Effect of diiodobenzotefa on the functionally different subpopulations of T-lymphocytes]. / Deistvie diiodbenzotéfa na funktsional'no razlichnye subpopuliatsii T-limfotsitov.

Diiodobenzo-tepa (DIB) was given orally to CBA mice in a dose of 25 mg/kg for 3 successive days. The number of nucleus-containing cells decreased 3.9 fold in the thymus and 1.4 fold in the bone marrow. In experiments on transplantation of lymphoid cells to intact or lethally irradiated (CBA X C57BL/6J)F1 mice treated with DIB this substance did not influence the helper activity of T lymphocytes but inhibited the activity or B and T lymphocytes, inducing "graft-versus-host" and T cell-suppressor functions.
