Abstract

We experienced a cose of occupational asthma induced by the tobacco leaf in 49-year old man. He has worked at the Korean Tobacco and Ginseng company for 23 years but suffered from the intermittent mild wheezing and dyspnea since 6 years ago. He has not involved in the process making the tobacco directly, but just managed it at the storage barn. He showed a whole negative reaction to 55 inhalant allergens(Bencard, UK) and the allergen extracted from the yellow Korean tobacco leaf, but showed the dual asthmatic respose to the allergen bronchial provocation test with it. His basal PC is 6.35 mg/ml with methacholine inhalation challenge. Now he changed the workplace far away from the barn at the same company and is treated with bronchodilator and anti-asthmatic inhaler.
