Peritoneal macrophages from Sarcoma-180-bearing mice against Staphylococcus aureus were studied to determine the in vitro phagocytic capacities. When the phagocytic system was opsonized with normal mouse serum, macrophage phagocytic activity increased markedly soon after tumour graft and then returned to normal. A new antiphagocytic factor was detected in the serum of tumour-bearers soon after tumour implantation. This factor was of tumour origin, stable even at a temperature of 56 degrees C for 30 min and non-dialysable. Peptone-starch-induced macrophages were less sensitive to the factor than their unstimulated counterpart.
对荷肉瘤180小鼠的腹膜巨噬细胞针对金黄色葡萄球菌的体外吞噬能力进行了研究。当吞噬系统用正常小鼠血清调理后,肿瘤移植后不久巨噬细胞吞噬活性显著增加,然后恢复正常。肿瘤植入后不久在荷瘤小鼠血清中检测到一种新的抗吞噬因子。该因子起源于肿瘤,即使在56℃温度下30分钟仍稳定且不可透析。蛋白胨-淀粉诱导的巨噬细胞对该因子的敏感性低于未受刺激的巨噬细胞。
