title: [Study on depressant effects of THPS on S180 tumor-bearing-mice and its mechanisms].
abstract: OBJECTIVE
  to study depressant effect of total hedysarum polybotys saccharids (THPS) on S180 tumor-bearing-mice and its mechanisms.
  
  
  METHODS
  THPS was extracted from Radix Xedysari with water and precipitated with ethanol, determining its molecular weight, purity, saccharide and aldonic acid content. 90 Kunming mice were divided into 9 groups randomly. One group was the normal group, the others were divided into 8 groups randomly after inculating S180 tumors and were treated with THPS and THPS combination cyclophosphamide (CY) in low, moderate and high dose, to put them to death after 14 days. To determine every tumor weight, the rate of depressant tumor, the contents of IL-2 and TNF-alpha with ELISA, and NF-kappaB with immunochemistry.
  
  
  RESULTS
  The moderate dose THPS conspicuously possessed a depressant effect on S180 tumor and joint action with combination CY and increased the contents of IL-2, TNF-alpha and NF-kappaB of mice.
  
  
  CONCLUSIONS
  THPS of moderate dose possesses a depressant effect on S180 tumor through increasing the contents of IL-2, TNF-alpha and NF-kappaB of mice.
