采用抗ＣＤ_３单克隆抗体和重组白细胞介素２共刺激外周血单个核细胞并经重组白细胞介素２扩增制备抗ＣＤ３单克隆抗体激活的杀伤细胞（ＣＤ３ＡＫ）。细胞化学研究表明５６．５％的ＣＤ３ＡＫ为酸性非特异性酯酶阳性淋巴细胞，糖原过碘酸雪夫反应阳性细胞和酸性磷酸酶阳性细胞较对照增多。
Peripheral blood mononuclear cells were co-stimulated with anti-CD_3 monoclonal antibody and recombinant interleukin-2 and anti-CD3 monoclonal antibody activated killer cells (CD3AK) were prepared by recombinant interleukin-2 amplification. Cytochemical studies showed that 56.5% of CD3AK was acidic non-specific esterase-positive lymphocytes, glycogen periodic acid Schiff response positive cells and acid phosphatase positive cells increased compared with the control.
