Abstract
Histamine release from basophils induced by anti-IgE was examined in 14 asthmatic subjects with blood eosinophilia. The subjects were divided into two groups; group I (with blood eosinophilia, positive skin test and positive RAST to house dust) and group II (with blood eosinophilia, negative skin test to various allergens and negative RAST to house dust). 1. Serum IgE levels in group I were much higher than those in group II. 2. Maximum percent histamine release induced by anti-IgE was much higher in group I than in group II. 3. Dose-response curve of anti-IgE-induced histamine release in group I showed consistent increase as anti-IgE concentrations increased. while, dose-response curve in group II was very low. These findings suggested that blood eosinophilia in group I might be elicited relating to IgE-mediated reaction. However, mechanism causing eosinophilia in group II was not clear in the present study.

末梢血好酸球増多を示す気管支喘息14症例について,抗ヒトIgE による好塩基球からのヒスタミン遊離を検討した. ハウスダストに対する皮内反応およびRASTが陽性を示す症例群(groupI)では,血清IgE値が高く,また抗ヒトIgEによるMax. % ヒスタミン遊離も高く(50.7士5.0%),そのdoseresponse curveは抗ヒトIgE添加濃度が高くなるにつれて上昇する傾向を示した.一方種々のアレルゲンエキスに対する皮内反応が陰性で,かつRAST も陰性を示す症例群(group II)では,血清IgE値が低く,また抗ヒトIgEによるMax. % ヒスタミン遊離も低く(10.5士1.7%),そのdose-response curveは全般的に低く,抗ヒトIgE添加濃度が高いところではむしろ抑制される傾向を示した.
