观察正常儿童与变应性鼻炎患儿外周血Ｔ细胞亚群分布的差异。方法：用间接免疫荧光法随机检测儿童变应性鼻炎组１６例和正常对照组２０例，并进行统计学分析。结果：变应性鼻炎组外周血中ＣＤ３、ＣＤ４、ＣＤ８较对照组均有明显下降。结论：Ｔ细胞亚群分布的改变是变态反应性疾病免疫功能紊乱的重要环节，可以作为变应性疾病的监测指标。
To observe the distribution of T cell subsets in peripheral blood of normal children and children with allergic rhinitis. Methods: Indirect immunofluorescence method was used to detect 16 children with allergic rhinitis randomly and 20 normal controls. Statistical analysis was performed. Results: The levels of CD3, CD4 and CD8 in peripheral blood of allergic rhinitis group were significantly lower than those in control group. Conclusion: The change of distribution of T cell subsets is an important part of immune dysfunction in allergic diseases and can be used as a monitoring indicator of allergic diseases.
