作者研究了结核感染病人外周血、胸水和腹水中淋巴细胞亚群的变化。研究的对象是新近感染病人(Mantoux皮肤试验转阳者)和过去曾诊断为结核病的病人(有器质性病变者)。结果表明,新近感染者常有外周血中淋巴细胞增多,包括表达TCR-αβ或TCR-γδ的T淋巴细胞。CD_4和CD_8阳性细胞数亦见有增加。但是在过去曾诊断为结核病者中则未发现外周血中淋巴细胞亚群分布上的变 The authors studied the changes of lymphocyte subsets in peripheral blood, pleural effusion and ascites of patients with tuberculosis infection. The subjects of the study were newly infected patients (Mantoux skin test positive) and those who had previously been diagnosed as having tuberculosis (those with organic disease). The results show that newly infected peripheral blood lymphocytes often include TCR-αβ or TCR-γδ expression of T lymphocytes. There was also an increase in the number of CD 4 and CD 8 positive cells. However, the distribution of lymphocyte subsets in peripheral blood was not found in those who had previously been diagnosed as having tuberculosis
