Molecular recognition patterns of sesquiterpene lactones in costus-sensitive patients.

Contact Dermatitis 15(4) , 223-30, (1986)

A molecular analysis of cross-reactions in costus-sensitive patients reveals that the most active sesquiterpene lactones are the ones with the lesser number of oxygenated substituents close to the alpha-methylene-gamma-butyrolactone ring. Cross-reactions with...

Dioxopromethazine-induced photoallergic contact dermatitis followed by persistent light reaction.

Am. J. Contact Dermatitis 9(3) , 182-7, (1998)

Although photosensitivity after photoallergy to topical phenothiazine antihistamines is well known, there have been no previous reports of dioxopromethazine inducing this phenomenon.A housewife used 0.5% dioxopromethazine in Prothanon gel for palpebral prurit...

[Skin sensitization of costus root oil and peripheral lymphocyte count in gastric and colon cancers].

Gan To Kagaku Ryoho. 11(1) , 81-6, (1984)

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 s...

[Costus root oil test in cancer patients; correlation with tumor stage].

Gan No Rinsho. 29(11) , 1319-22, (1983)

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 patie...

[Cutaneous delayed hypersensitivity to costus root oil in lung cancer].

Gan No Rinsho. 31(11) , 1362-6, (1985)

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 ...

[Effect of costus root oil in murine tumors].

Gan To Kagaku Ryoho. 14(7) , 2276-9, (1987)

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 ...
