The effects of cyclophosphamide (200 microgram/ml), levamisole (1 microgram/ml) and Concanavalin A (10 microgram/ml) on the in vitro IgE biosynthesis of lymphocytes from 2 allergic children and six healthy adults were studied. The capability of the IgE biosynthesis was enhanced by cyclophosphamide in nine allergic children, suppressed by levamisole in three and not changed by Concanavalin A. The three patients who showed in vitro suppressed IgE synthesis by levamisole had been treated with levamisole for more than three months but only one revealed decreased serum IgE.
