本文应用螨口服液对毛细支气管炎（毛支）进行免疫防治，以期降低哮喘息病率。结果用螨口服液防治的36例毛支中仅2例（5．56％）发展为哮喘，而未行防治的对照组42例中15例（35．71％）患哮喘，两组有显著差异（P＜0．01）。防治组经螨口服液治疗后免疫指标有明显变化，CD3、CD8较前增高，CD4／CD8比值及IgE水平下降（P＜0．01）。提示螨口服液不仅是预防或降低毛支后哮喘息病率的有效方法，对毛支患儿失衡的免疫功能也有调节作用。
In this paper, mite oral solution of bronchiolitis (capillary) immune control, with a view to reduce the incidence of asthma. Results Only 2 of 36 cases (5.56%) of the hairy branches treated with acarid oral solution developed asthma, whereas 15 cases (35.71%) had asthma in the 42 cases without control, with significant difference between the two groups Difference (P <0.01). After treatment with mite oral solution, the immune index of the prevention and cure group changed obviously, the CD3 and CD8 increased, the ratio of CD4 / CD8 and the level of IgE decreased (P <0.01). Tip mite oral solution is not only an effective way to prevent or reduce the prevalence of asthma in the hair branch, but also play an adjusting role in the unbalanced immune function.
