以往研究较普遍认为吸入型β_2-肾上腺素受体激动剂仅抑制早发型哮喘反应(EAR),而对迟发型哮喘反应(LAR)及伴随的支气管反应性增高无抑制作用。本文旨在探讨大剂量舒喘宁气雾剂对过敏原诱发的 EAR、LAR 和支气管反应性增高的影响。病人和方法 10例变应性轻症哮喘患者,男6例,女4例,平均年龄21岁。FEV_1平均基 It has been generally accepted in the past that inhaled β 2 -adrenergic agonists only inhibit early onset asthmatic response (EAR), but not delayed onset asthmatic response (LAR) and accompanying bronchial reactivity. This article aims to investigate the effects of high-dose salbutamol aerosol on allergen-induced increases in EAR, LAR and bronchial reactivity. Patients and Methods 10 patients with allergic mild asthma, 6 males and 4 females, mean age 21 years. FEV_1 average basis
