摘要 目的通过观察哮喘模型大鼠在吸烟及戒烟后大体症状、肺功能、肺泡灌洗液(BALF)细胞分类及血清炎症介质的变化,探讨吸烟与戒烟对哮喘患者影响。方法健康雄性Wistar大鼠40只,随机分为对照组、致敏组、吸烟致敏组、戒烟致敏组,每组10只。观察各组大鼠大体症状,测定各组大鼠肺功能,行支气管肺泡灌洗液细胞分类计数,取血清以ELISA方法测定IL-13、IgE蛋白质含量。结果哮喘模型大鼠制备成功;被动吸烟后呼吸急促、喘鸣等症状加重,肺通气功能减低,肺泡灌洗液中中性粒细胞比例上升,血清IL-13、IgE水平上升;而戒烟后喘息症状略有减轻,肺功能短期内即有恢复,肺泡灌洗液中中性粒细胞比例下降,血清IgE水平下降。结论吸烟可加重哮喘模型大鼠喘息症状,使得肺通气功能进一步减低,炎症反应加重;通过戒烟,可明显改善哮喘模型大鼠生存状态,建议及早戒烟。
