以荷瘤动物模型观察清肝消疒徵丹抗肿瘤作用。结果：清肝消疒徵丹高、中、低剂量对小鼠移植性肝癌（Ｈｅｐ）的抑制率为４７．５７％，４４．６６％和３９．８１％；对Ｌｅｗｉｓ肺癌的抑制率为４２．９２％，３９．３３％和３１．９１％；对肝癌腹水型小鼠生命延长率为５０．５４％，４６．９５％和３３．５５％；与生理盐水组比较有显著性差异（Ｐ＜０．０５），能促进荷瘤小鼠血清抗体（溶血素）的生成；提高外周血Ｔ淋巴细胞（Ｔ）、辅助性Ｔ细胞（Ｔｈ），纠正Ｔｈ／Ｔｓ的比值异常，拮抗化疗药ＦＴ－２０７对此类细胞的抑制作用；提高自然杀伤细胞（ＮＫ）的活性。提示本药有较好的抑瘤和免疫调节作用，能使荷瘤小鼠低下状态的免疫功能提高
The tumor-bearing animal model was used to observe the anti-tumor effects of Qinggan Xiaoqin Zhengdan. RESULTS: The inhibitory rate of high-, middle-, and low-dose Qinggan Xiaozheng Dandan on transplanted hepatocellular carcinoma (Hep) in mice was 47.57%, 44.66%, and 39.81%; the inhibition rate on Lewis lung cancer was 42%. .92%, 39.33% and 31.91%; Life-threatening rates of ascites mice with hepatocellular carcinoma were 50.54%, 46.95% and 33.55%; Significant differences compared with saline group (P) <0.05), can promote the generation of serum antibody (hemolysin) in tumor-bearing mice; increase peripheral blood T lymphocytes (T), helper T cells (Th), correct ratio of Th/Ts abnormalities, and antagonize chemotherapy drugs Inhibitory effects of FT-207 on these cells; increased natural killer (NK) activity. It is suggested that the drug has a good effect of inhibiting tumor and immune regulation, and can improve the immune function of the tumor-bearing mice in a depressed state.
