[Effect of levamisole on lymphoid cells in vitro]

The paper is concerned with a study in the levamisole effect on lymphoid cells of bone marrow, thymus, spleen and lymph nodes of guinea pigs and CBA/mice. It is shown that levamisole stimulates the differentiation of immature bone marrow and thymus lymphocytes and restores the rosette-forming ability of thymocytes previously heated at 45 degrees C for an hour.
