为了研究支气管哮喘的发病机理，对22例慢性支气管哮喘轻中度加剧期患者进行嗜酸性细胞阳离子蛋白（ECP）和肺功能一秒钟用力呼气量（FEV1）、50％肺活量最大呼气流量（V50）、25％肺活量最大呼气流量（V25）及其占预计值百分率测定，探讨支气管哮喘炎症、气道高反应性（AHR）
In order to study the pathogenesis of bronchial asthma, 22 patients with mild to moderate exacerbation of chronic bronchial asthma were evaluated for eosinophil cationic protein (ECP) and forced expiratory volume in one second (FEV1), maximal expiratory flow rate of 50% (V50), maximum expiratory flow (V25) of 25% and its percentage of predicted value were measured to explore the relationship between bronchial asthma inflammation, airway hyperresponsiveness (AHR)
