title: [Immunoallergological studies on chironomid antigen in bronchial asthma].
abstract: Immuno-allergological studies on Tokunagayusurika akamusi (TA), a chironomid, were carried out in 217 patients with bronchial asthma. 1. Skin reaction to TA was positive in 72 (33.2%) out of the 217 patients with bronchial asthma. 2. Fifteen (13.8%) of the 109 patients showed a significant amount of histamine release (more than 15%) from basophils stimulated by TA antigen. 3. There was a significant correlation between skin reaction and histamine release by TA antigen. 4. A significant amount of basophil histamine release was observed in young patients, and in those who were under 40 years old of age at the onset of the disease. The serum IgE concentration of these patients was relatively high. 5. There was a significant correlation between basophil histamine release by TA antigen and specific IgE antibody to CTT. 6. There were no significant differences in skin reaction or histamine release by TA antigen between asthmatics in Okayama and Tottori prefectures.
