观察了党参多糖及IL-2体内抗肿瘤作用.体内单用IL-2或党参多糖(CPPS)有抗S180肉产瘤作用,二者联合用药时有协同作用.荷瘤小鼠的淋巴细胞增殖试验表明,单用CPPS对髀细胞无自发增殖作用,但对Con-A诱导之脾细胞增殖有促进作用,联合用药时,作用更为明显.结果提示CPPS与IL-2有体内协同抗肿瘤作用,该作用的环节之一是增强了机体的免疫功能. Observed the anti-tumor effect of Dangshen Polysaccharides and IL-2 in vivo. IL-2 or Codonopsis polysaccharides (CPPS) alone had anti-S180 effect on tumorigenicity in vivo. There was synergy when the two drugs were combined. Lymphocyte proliferation in tumor-bearing mice. The experiment showed that CPPS alone had no effect on the proliferation of sputum cells, but it promoted the proliferation of splenocytes induced by Con-A, and the effect was more obvious when the drugs were combined. The results suggest that CPPS and IL-2 have a synergistic antitumor effect in vivo. One of the aspects of this role is to enhance the body’s immune function.
