[Effect of levamisole on the cytotoxic activity of normal lymphocytes in tissue culture].

Preliminary incubation of normal non-immune spleen lymphocytes from C57BL/6j and BALB/c mice with levamisole (1 . 10(-4) - 1 . 10(-5)M) for 45 min at 37 degrees C with subsequent wash-out resulted in potentiation of the cytotoxic effect with respect to allogenic target cells (L-cells). Simultaneous administration of lymphocytes and levamisole to a culture of target cells did not produce cytotoxic effect.
