本文测定10例癌症患者(包括乳腺癌、结直肠癌、胃癌、食管癌、急性粒细胞性白血病)外周血淋巴细胞对无关靶-7402人体肝癌细胞株的天然杀伤(NK)活性。以抑制靶细胞的贴壁率为指标。经贴壁粘附去掉单核细胞,用抗胸腺血清去除T淋巴细胞及密度梯度离心去掉IgGFc受体阳性细胞(Fc-
In this paper, the natural killer (NK) activities of peripheral blood lymphocytes from 10 cancer patients (including breast, colorectal, gastric, esophageal and acute myeloid leukemia) on unrelated target-7402 human hepatoma cell lines were determined. To inhibit the target cell adhesion rate as an indicator. Monocytes were removed by adherent adhesion, T lymphocytes were removed using anti-thymus serum and density gradient centrifugation to remove IgGFc receptor-positive cells (Fc-
