济南假单胞菌细胞壁组分（ＰＪ－ＣＷ）是我院药物所研制的一种微生物制剂，本研究以荷瘤小鼠为模型，以短小棒状菌苗为阳性对照，初步观察了ＰＪ－ＣＷ的抗癌作用。结果显示，ＰＪ－ＣＷ能显著抑制小鼠移植瘤的生长，保护荷瘤小鼠胸腺的功能，且能明显增强荷瘤小鼠Ｍφ的吞噬功能和ＮＫ细胞的杀伤活性，提高荷瘤小鼠外周血淋巴细胞ＡＮＡＥ阳性细胞数。 PJ-CW is a microbial preparation developed by our hospital. In this study, tumor-bearing mice were used as models, and short coryneform bacterins were used as positive controls. PJ-CW was initially observed. The anti-cancer effect. The results showed that PJ-CW can significantly inhibit the growth of transplanted tumors in mice, protect the thymus function of tumor-bearing mice, and can significantly enhance the phagocytosis of tumor-bearing mice and the killing activity of NK cells, and increase the tumor-bearing mice periphery. The number of ANAE positive cells in blood lymphocytes.
