本文用细胞化学方法观察某些恶性肿瘤患者外周血T淋巴细胞(46例,其中女性10例)和T_μ、T_γ淋巴细胞(30例,女性10例)百分率及其比值的变化,结果表明大多数肿瘤患者外周血T、T_μ淋巴细胞数明显降低,其均值约为对照值的73%和79%,而T_γ淋巴细胞则显示出不同程度的升高.与恶性淋巴瘤相比,癌瘤患者T淋巴细胞下降的程度更为明显.上述T_μ、T_γ淋巴细胞百分率的变化导致T_μ/T_γ比值明显降低.
Cytochemistry was used to observe the percentage of T lymphocyte (46 cases, 10 cases of female) and T_μ and T_γ lymphocytes (30 cases, 10 cases of female) in patients with malignant tumor. The results showed that most of the cases The number of T and T_μ lymphocytes in the peripheral blood of patients with cancer was significantly lower than that of the control group (73% and 79%, respectively), while T_γ lymphocytes showed different degrees of increase.Compared with malignant lymphoma, T The degree of lymphocyte descent was more obvious.The change of the percentage of T_μ and T_γ lymphocytes resulted in a significant decrease of T_μ / T_γ ratio.
