摘要 目的:研究不同致敏和激发时间对建立哮喘气道炎症和气道反应性的作用。方法:采用早致敏早激发(5周龄致敏9周龄激发),早致敏晚激发(5周龄致敏49周龄激发),晚致敏晚激发(45周龄致敏49周龄激发)的方法,观察不同致敏和激发时间对诱导小鼠气道反应性、肺部嗜酸粒细胞炎症和黏液分泌的作用。结果:早致敏早激发和早致敏晚激发两组均表现出气道反应性显著升高,嗜酸粒细胞浸润以及黏液分泌增多,与各自阴性对照比较差异显著,晚致敏晚激发的方法不能诱发气道高反应性和肺部炎症。此外,在两组早致敏模型组,经过不同时间间隔激发,早致敏早激发组嗜酸粒细胞浸润和黏液分泌较早致敏晚激发组明显。结论:早期致敏时间决定哮喘炎症的诱发,致敏和激发的时间间隔影响炎症的严重程度。早致敏晚激发的方法可能作为晚发型哮喘模型的建立方法。
