Spleen lymphocytes from five patients with Hodgkin's disease (HD) type mixed cellularity and five normal controls were studied. An increased percentage of 'null cells' was observed in three out of the five patients studied. The two other patients had increased percentage of T lymphocytes. Lymphocytes from spleen with HD had a decreased ability to respond to suboptimal concentrations of T cell mitogens. When these cells were fractionated in a discontinuous density gradient a subpopulation of cells, unable to respond to Con A, was recovered from the dense cell fractions. The implications of the present findings to the understanding of the physiopathological changes in HD are discussed.
对5例混合型细胞性霍奇金病(HD)患者和5名正常对照者的脾脏淋巴细胞进行了研究。在所研究的5例患者中,有3例观察到“裸细胞”百分比增加。另外2例患者的T淋巴细胞百分比增加。HD患者脾脏中的淋巴细胞对次优浓度T细胞有丝分裂原的反应能力下降。当这些细胞在不连续密度梯度中进行分级分离时,从高密度细胞级分中回收了一群无法对刀豆球蛋白A作出反应的细胞。讨论了本研究结果对理解HD生理病理变化的意义。
