关于肿瘤免疫问题,近年来从各个不同角度有很多研究报道:机体抗肿瘤的免疫能力包括细胞免疫和体液免疫两方面,并以细胞免疫为主,有淋巴细胞和巨噬细胞参与。而巨噬细胞的吞噬作用的体内或体外测定,又可做为特异性和非特异性免疫的一个重要指标。我们采用中国医学科学院肿瘤防治研究所介绍的方法,,略加简化,在体外对肿瘤病人巨噬细胞的吞噬活性进行了测 On the issue of tumor immunity, there have been many reports from various perspectives in recent years: The body’s anti-tumor immunity includes cellular immunity and humoral immunity, and is mainly based on cellular immunity, with the involvement of lymphocytes and macrophages. The in vivo or in vitro assay of macrophage phagocytosis can be used as an important indicator of specific and nonspecific immunity. We adopted the method introduced by the Cancer Prevention Research Institute of the Chinese Academy of Medical Sciences to simplify the phagocytic activity of macrophages in tumor patients in vitro.
