[Action of levamisole on lymphocytic reactivity in naso-laryngeal carcinoma]

It was confirmed that the mitogenic reactivity and rosette-forming cells capacity of T and B lymphocytes were depressed in nose-pharyngeal tumor bearing patients. Using levamisole treatment, the response of T cells was increased till almost the normal value. B cells response was normal or slightly increased after levamisole treatment. Our experiments suggests that the levamisole is capable to induce an increased response of the immune system when compared to untreated tumor bearing patients.
