Natural Killer (NK) activity by blood lymphocytes from healthy males was determined in 4-h-51Cr release assay with K562 target cells. Individuals with a high ratio of neutrophils to lymphocytes had a significantly lower NK activity compared with that of those with a low ratio of neutrophils to lymphocytes. On the other hand, no correlation of NK activity with absolute lymphocyte count was observed. Eosinophilia in blood was found to be accompanied by increased NK activity. Some biological aspects of these interdependences are discussed.
采用K562靶细胞，通过4小时51铬释放试验测定健康男性血液淋巴细胞的自然杀伤（NK）活性。中性粒细胞与淋巴细胞比例高的个体，其NK活性显著低于中性粒细胞与淋巴细胞比例低的个体。另一方面，未观察到NK活性与淋巴细胞绝对计数之间存在相关性。发现血液嗜酸性粒细胞增多伴有NK活性增加。讨论了这些相互关系的一些生物学方面。
