【摘要】 鉴于国内还缺乏正常人外周血T细胞亚群的有关资料,我们利用单克隆抗体T₁₁、T₄和T₈及免疫细胞化学技术对一组成年人外周血中T细胞及其亚群分布进行了研究。我国正常人外周血中T细胞、T₄⁺细胞及T₈⁺细胞在单个核细胞中的比例分别为65.89±8.31;43.38±7.48;25.03±6.41％。无明显性别差异,但50～69岁老年人前期T细胞及T₄⁺细胞有所降低,而T₈⁺细胞有增高趋势。同时我们还发现血中的T细胞及其亚群存在日间节律性变动,建议应在每天上午8～9时采血。更多还原

【Abstract】 The normal volue of peripheral blood T lymphocyte subpopulation in Normal Chinese adults was determined using monoclonal antibodies T₁₁, T₄ and T₈, and immunocytochemistry. The results showed that in normal adults, T cells accounted for 65.89±8.31, 43.38±7.48 and 25.03±6.41% no sex differencn could be found. In 50-60 years aged people T cells and T₄⁺ cells decreased. Furthermore, we found the volue of T lymphocyte subpopulations in peripheral blood drawed in the afternoon was different from that drawed in the morning, suggesting that when the T lymphocyte subpopulation should be tested, the blood should be drawn at 8-9 AM.更多还原
