costus loangensis/hypersensitivity

Costus oil, an iol isolated from a Composite, Saussurea lappa C., used in perfumery, is responsible of numerous cases of allergic contact dermatitis (ACD). The haptens incriminated are sesquiterpene lactones, costunolide and dehydrocostuslactone. These lactones can be removed from the oil by using a

BACKGROUND Saussurea costus (Falc.) Lipsch. root has been used in Asian traditional medicine for the treatment of asthma, rheumatism, and other conditions. S. costus extracts were shown to alleviate house dust mite-induced atopic-like dermatitis in Nc/Nga mice; besides, sesquiterpene lactones were

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
