九节龙皂苷Ⅰ的抗肿瘤作用和免疫调节作用

目的研究九节龙皂苷Ⅰ对S180、H22、EAC和L1210荷瘤小鼠的治疗作用及对荷瘤小鼠免疫功能的影响。方法小鼠右腋皮下(或腹腔)接种瘤细胞复制荷瘤小鼠模型。连续灌胃给药九节龙皂苷Ⅰ8 d后,剥离瘤块,计算抑瘤率;3H-TdR参入法研究了其对脾淋巴细胞增殖的影响,腹腔巨噬细胞吞噬鸡红细胞法测量了其对巨噬细胞吞噬功能的影响。结果九节龙皂苷Ⅰ对小鼠S180、H22和EAC实体瘤均有抑制作用,其100 mg.kg-1对3种移植瘤最大抑瘤率分别为38.7%、48.6%和50.0%;并能促进荷瘤小鼠脾T淋巴细胞增殖,提高巨噬细胞吞噬能力。结论九节龙皂苷Ⅰ能抑制小鼠移植性肿瘤生长,并能改善荷瘤小鼠免疫功能。

Antitumor and immunological regulation effects of ardipusilloside-Ⅰ

Aim To study the antitumor and immunological regulation effects of ardipusilloside-Ⅰ(ADS-Ⅰ) on tumor-bearing mice of S180, H22, EAC and L1210. Methods The tumor-bearing mouse model was made through injecting cancer cells in the right limb oxter(or in abdominal cavity), and the mice were administrated orally with ADS-Ⅰfor 8 days. Then we detached the tumor and counted the inhibition rate of tumor growth. Incorporation of ()~3H-TdR was used to assess the proliferation of T spleen lymphocyte cells; phagocytosis of abdominal cavity macrophage was measured with the method of chicken red blood cells. Results ADS-Ⅰ was proved to be effective on the tumor-bearing mice of S180, H22 and EAC, and the maximal inhibition rate of the dose of 100 mg·kg~(-1) was 38.7%, 48.6% and 50.0%, respectively;ADS-Ⅰ promoted the proliferation of T spleen lymphocyte cells,and strengthened the phagocytosis of macrophage in the tumor-bearing mice significantly. Conclusion ADS-Ⅰ can inhibit the growth of transplanted tumor,and improve the immunological function of tumor-bearing mice.
