RESUMO
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.
