摘　　要：采用双抗夹心EIASA法测定30例哮喘发作期、12例哮喘缓解期患儿血浆及外周血单个核细胞(PBMC)白细胞介素4(IL-4)、白细胞介素12(IL-12)与血清IgE的水平,结果表明:哮喘患儿发作期、缓解期血清IgE水平、血浆及PBMC经PHA和LPS刺激后的IL-4水平较正常对照组明显升高(P<0.01),IL-12水平较正常对照组明显降低(P<0.01)。且缓解期IgE、IL-4及IL-12水平较发作期均有明显差异(P<0.05)。提示哮喘患儿发作期及缓解期均存在IgE、IL-4及IL-12水平失衡。In this study, IL-4 and IL-12 levels in plasma and peripheral blood mononuclear cells (PBMC) as well as serum IgE level were prospectively assessed with double-antibody sandwich ELISA technique in children with asthma during the attack group (30 cases)and the interval group(12 cases). The results observed revealed that serum IgE level and IL-4 level in plasma and PBMC after PHA and LPS provocation during both of the attack stage and the interval stage were found to be evidently higher than those of the normal control group (P<0. 01). Otherwise,IL-12 level during both stages was much lower than that of the normal control(P<0. 01). In other hand,there were found to have a significant difference in all these 3 data between attack and interval stages. Thus, the conclusion indicates that there might be an imbalance of IL-4,IL-12 and IgE level in children with asthma during both of the attack and the interval stages.
