本文应用人肺腺癌（Ａｎｉｐ９７３）人结肠癌（ＨＣ）实验模型证明：黄芪多糖（ＡＰＳ）制剂有明显的抑瘤作用，ＡＰＳ腹腔内注射０．５ｍｌ／天连续二周，Ａｎｉｐ９７３组ＡＰＳ的抑瘤率为３３％，Ｐ＜０．０１；与对照组相比差异显著。ＨＣ组ＡＰＳ抑瘤率为２０％，Ｐ＞０．０１；无显著意义。实验中我们发现ＡＰＳ无毒性、无副作用，不使裸小鼠体重、脾重量减轻，显然ＡＰＳ对各种肿瘤的治疗，可增强机体的免疫功能，抗病毒感染有着重要的临床意义。
In this paper, the experimental model of human colon cancer (HC) in human lung adenocarcinoma (Anip973) was used to prove that APS preparations have significant anti-tumor effect. APS was intraperitoneally injected in 0.5 ml/day for two weeks, and APS in the Anip973 group was inhibited. The tumor rate was 33%, P<0.01; the difference was significant compared with the control group. The tumor inhibition rate of APS in HC group was 20%, P>0.01; there was no significant difference. In the experiment, we found that APS is non-toxic and has no side effects. It does not reduce body weight and spleen weight in nude mice. Obviously, APS treatment for various tumors can enhance the body’s immune function, and anti-virus infection has important clinical significance.
