The spore of Lycopodium clavatum (called "sekishoshi" powder) is often put to use in the manufacturing process of artificial tooth by dental technicians. A case with bronchial asthma is reported, who was treated and observed recently, and considered to be caused by Lycopodium spore. T.Y., a dental technician, 27 years of age, visited our clinic with the complaint of frequent occurence of asthmatic attacks since 2 years. Asthmatic attacks had no relation to diet, but to the sudden lowering of temperature and dusty surroundings, and the attacks always occured after the work using Lycopodium spore powder. The remarkable peripheral leucocytic eosinophilia was not noticed, but eosinophilia in nasal smear was observed. In the intracutaneous test with inhalatory allergen extracts, positive reaction was proved to house dust, hemp-cloth, rice straw, Japanese hop (Humulus japonicus) pollen, sausage and cheese. The intracutaneous test, conjunctival test and Prausnitz-Kustner's passive transfer test with self-prepared extract of Lycopodium spore were also carried out, and consequently positive reactions were assured. And the clinical schedule of hyposensitization therapy with house dust and lycopodium spore extracts is now in progress. Judging from the above-mentioned clinical history and the results of allergic investigations, this case is considered to be the subject with occupational allergic asthma caused by Lycopodium spore.
