对支气管哮喘（简称哮喘）发作期患者的末梢血及支气管粘膜内的嗜酸粒细胞（ＥＯＳ）与一秒钟用力呼气容积（ＦＥＶ１．０）的关系进行了研究，结果发现：哮喘发作期患者末梢血及支气管粘膜内ＥＯＳ显著增高（Ｐ＜０．０１），ＦＥＶ１．０明显下降，它们之间有相关性（ｒ＝０．６２３０，Ｐ＜０．０５）。提示：哮喘发作期患者ＦＥＶ１．０降低与末梢血及支气管粘膜内ＥＯＳ增多有关。
The relationship between peripheral blood and bronchial mucosal eosinophils (EOS) and forced expiratory volume per second (FEV1.0) in patients with bronchial asthma (asthma) attack was studied. The results showed that the duration of asthma attack EOS in patients with peripheral blood and bronchial mucosa was significantly higher (P <0.01), FEV1.0 significantly decreased, there is a correlation between them (r = 0.6230, P <0.05). Tip: Reduced FEV1.0 in patients with asthma attack is associated with increased EOS in peripheral blood and bronchial mucosa.
