     【摘要】目的探讨胸腺素α1(Tα1)对哮喘患者Th1/Th2免疫反应的调节以及其对气道高反应性的抑制作用。方法选取缓解期哮喘患者25例(哮喘组)，给予胸腺素α1(Tα1)隔日一次皮下注射，每次1 mg/kg，疗程15月。健康志愿者(对照组)15名。分别对哮喘组用药前、后，对照组留取血标本，采用双抗体夹心酶联免疫吸附法(ELISA)检测上述三组血清中IL4、IL5、IFNγ含量，并对检测结果进行统计学处理。结果哮喘组用药前血清中IL4含量[(5215±896) pg/mL]与对照组[(1333±1116) pg/mL]比较差异有显著性(P<001)。哮喘组用药后血清IFNγ量[(118552±6710 )pg/mL]显著增加，与对照组[(13825±625 )pg/mL]和用药前[(14458±106) pg/mL]相比均有显著性差异(P＝0001)；IL4含量[(1415±486) pg/mL]较用药前[(5215±896) pg/mL]明显降低(P＝0001)。结论本研究显示：Tα1能上调Th1型免疫反应，下调Th2型免疫反应，抑制IL4和IL5的过度表达，从而对哮喘患者的气道高反应性有治疗和抑制作用。
