采用人Ｔ细胞单克隆抗体（ＭＣＡｂ）间接荧光法，用ＭＣＡｂ及ＦＩＦＣ标记羊抗鼠ＩｇＧ抗体测定４３例３个月至１２岁哮喘患儿及同年龄组的２９例健康儿，分别检测外周静脉血ＣＤ３＋、ＣＤ４＋、ＣＤ８＋及Ｂ细胞的百分率，ＣＤ４＋／ＣＤ８＋的细胞比值。结果显示，哮喘患儿的发病可能主要与免疫紊乱有关。
Indirect fluorescence of human T cell monoclonal antibody (MCAb) was used to detect 43 healthy children with asthma aged from 3 months to 12 years and 29 healthy children of the same age with MCAb and FIFC goat anti-mouse IgG antibody. Peripheral venous Blood CD3 +, CD4 +, CD8 + and B cell percentage, CD4 + / CD8 + cell ratio. The results show that the incidence of asthma in children may be mainly related to immune disorders.
