最近发现,在体外IL-2与NK细胞活性有关联。IL-2产生于细胞介导免疫反应的早期,是一种较好的免疫指标。本文从14名健康成人、23例进行性恶性实体瘤病人中采集肝素抗凝血,分离血浆与淋巴细胞,然后将病人、对照者的淋巴细胞、血浆相互交配成4组,每组培养中包含10~6淋巴细胞、0.1％PHA-P、1％血浆、10~5经幅射的受EB病毒 It has recently been found that IL-2 is associated with NK cell activity in vitro. IL-2 is produced early in the cell-mediated immune response, is a good indicator of immunity. In this paper, anticoagulant heparin was collected from 14 healthy adults and 23 patients with progressive malignant solid tumors. Plasma and lymphocytes were separated from the patients. The lymphocytes and plasma of the patients and controls were then interlaced into 4 groups. Each group contained 10 to 6 lymphocytes, 0.1% PHA-P, 1% plasma, 10 to 5 irradiated Epstein-Barr virus
