近年来的研究表明β_2-微球蛋白(β_2m)为一重要的免疫相关分子,它参与很多免疫现象。我们以β_2m为免疫指标,对胃癌患者外周血淋巴细胞进行体外培养,用放免法测定了β_2m量。 恶良性病患者外周血淋巴细胞均能不同程度地产生β_2m,胃癌患者外周血淋巴细胞体外自发产生β_2m量与良性病变组无显著差别;若将PWM加入淋巴细胞培养液中,发现20例胃癌中有10例β_2m量明显低于对
In recent years, studies have shown that β_2-microglobulin (β_2m) is an important immune-related molecules, it is involved in many immune phenomena. We take β_2m as the immune index to culture the peripheral blood lymphocytes of gastric cancer patients in vitro and determine the amount of β_2m by radioimmunoassay. Peripheral blood lymphocytes in patients with malignant benign disease can produce β_2m to varying degrees. There is no significant difference in the amount of spontaneous β_2_2 produced by peripheral blood lymphocytes in gastric cancer patients compared with benign lesions. If PWM is added into lymphocyte culture medium, 20 cases of gastric carcinoma 10 cases of β_2m significantly lower than the right
