Embodiment 2
[0090] Example 2 Saizheng (BSG) inhibits and treats ascites in H22 ascites tumor mice
[0091] Experimental background and purpose: Malignant ascites is a fluid in the peritoneal cavity caused by the transfer of digestive system tumors or ovarian cancer through blood vessels and lymphatic vessels, tumor tissue ulceration of the serosa layer, or radical surgery, often due to the shedding of cancer cells and implantation metastasis in the peritoneal cavity. Abnormal accumulation. This experiment was to investigate the inhibitory and therapeutic effects of BSG on ascites in H22 ascites tumor mice.
[0092] Experimental materials: mouse liver cancer cell line H22, female mice, 6-8 weeks old, 18-22g. Saizheng (BSG, containing PIC 2mg / ml, the same below). The control drug cisplatin (DDP), sterile N.S (ie normal saline).
[0093] experimental method:
[0094] 1. Establishment of the H22 ascites tumor model: Take out the frozen ascites cells, thaw them, add them to the medium for ...
Embodiment 3
[0117] Embodiment 3 The inhibitory and therapeutic effect of the composition Saizheng (BSG) of the present invention on mouse malignant pleural effusion
[0118] Experimental background and purpose: Malignant pleural effusion usually refers to the pleural effusion caused by the metastasis of malignant tumor in the pleura or other parts to the pleura, accounting for about 50% of all clinical pleural effusions. This experiment explores the inhibitory and therapeutic effects of the composition of the present invention (BSG) on the generation of malignant pleural effusion in mice.
[0119] Experimental materials: mouse liver cancer cell line H22 (purchased from CCTCC), BALB / c mice, SPF grade, female, 6-8 weeks old, 18-22g, purchased from Beijing Weitong Lihua. Saizheng (BSG, 2mg / ml). The control drug Adorson (cyclophosphamide for injection), CTX, lot number 6D111A, 0.2g, Baxter Oncology GmbH. Sodium chloride injection, manufacturer Zhejiang Tianrui Pharmaceutical Co., Ltd., batc...
