应用流式细胞仪（ＦｌＯＷｃｙｔｏｍｅｔｒｙＦＣＭ）结合单克隆抗体对２４例急性白血病（ＡＬ）患儿治疗前及治疗后４Ｗ外周血反映细胞免疫功能的部分指标即天然杀伤细胞（ＮＫＣ）与Ｔ细胞亚群进行测定。结果表明：未经治疗的ＡＬ患者ＮＫＣ数量及Ｔ３、Ｔ４、Ｔ４／Ｔ８比值均明显低于正常对照组（Ｐ＜０．０１），治疗后ＮＫＣ、Ｔ３、Ｔ４及Ｔ４／Ｔ８比例均有不同程度的上升。提示：ＮＫＣ及Ｔ细胞亚群在ＡＬ的发生，发展上有重要作用
Flow cytometry (FlOWcytometryFCM) combined with monoclonal antibodies in 24 cases of acute leukemia (AL) children before and after treatment 4W peripheral blood reflect cellular immune function of some indicators of natural killer cells (NKC) and T cell subsets Determination. The results showed that the number of NKC and the ratio of T3, T4 and T4 / T8 in untreated AL patients were significantly lower than those in normal control group (P <0.01), and the proportions of NKC, T3, T4 and T4 / T8 after treatment were all different The degree of increase. Tip: NKC and T cell subsets play an important role in the occurrence and development of AL
