Costus root oil is a new primary sensitizer for examining the delayed, cell-mediated immune system. Ninety-nine patients with lung cancer were tested for skin reactions to costus root oil. The incidence of positive reactions to costus root oil decreased with the progress of lung cancer. The
Costus root oil is a new primary sensitizer to examine the delayed, cell-mediated immune system. The peripheral blood lymphocyte count has been measured in 68 cases of carcinoma of the stomach and colon. The count has been correlated with the stage of tumor spread and the patient's delayed
Delayed hypersensitivity skin responses to costus root oil were measured in patients with colon, stomach, breast and lung cancer and in healthy controls. Cancer patients were staged according to tumor spread. Differences were demonstrated between cancer patients and controls. Patients with localized
Costus root oil is a new primary sensitizer for examination of the delayed cell-mediated immune system. Histologic findings of skin producing a positive reaction to costus root oil show accumulation of lymphoid cells. If the delayed hypersensitivity reaction caused by costus root oil were to be used
