巨噬细胞（Mφ）具有广泛的生物学活性，在非特异性免疫防御，摄取和呈递抗原，活化T、B细胞，杀伤肿瘤细胞及免疫调节中均起重要作用。因此，测定Mφ活性是免疫学研究的一项有价值而常用的指标。实验中为获取更多的腹腔巨噬细胞（P－Mφ），常预先经腹腔注射各种诱导物。但各 Macrophages (Mφ) have a wide range of biological activities and play an important role in nonspecific immune defense, uptake and presentation of antigens, activation of T and B cells, killing of tumor cells and immune regulation. Therefore, measuring Mφ activity is a valuable and commonly used indicator of immunological research. In order to obtain more peritoneal macrophages (P-Mφ) in the experiment, various inducers are usually injected intraperitoneally. But all
