嗜酸粒细胞阳离子蛋白 (ECP)作为嗜酸粒细胞的特异性活化标志 ,与迟发性哮喘反应、气道慢性炎症和气道高反应性有着密切的关系 ,动态检测血清、痰或支气管肺泡灌洗液 (BALF)中的ECP水平 ,可有助于判断气道炎症的存在和程度 ,预测疾病的发作 ,同时还可评价抗炎治疗的效果 ,而痰或BALF中的ECP水平似更能反映气道局部的炎症情况。 Eosinophil cationic protein (ECP) as a specific activation markers of eosinophils, and delayed onset asthma, chronic airway inflammation and airway hyperresponsiveness are closely related to dynamic detection of serum, sputum or bronchoalveolar lavage The level of ECP in the wash fluid (BALF) can be helpful in determining the presence and extent of airway inflammation, predicting the onset of disease, and also in assessing the efficacy of anti-inflammatory therapies, while ECP levels in sputum or BALF appear to reflect more Local inflammation of the airways.
