    Abstract:
    OBJECTIVE: To observe the effect of panaxadiol saponin (PDS) and panaxtrol saponin (PTS) on proliferation of human bone marrow hemopoietic progenitor cells (HPC). METHODS: PDS and PTS were separated and purified from ginsenosides, and the effects on HPC were studied using in vitro hemopoietic progenitor cell colony-forming technique, by observing the proliferation of human burst forming unit-erythroid progenitor (BFU-E), colony-forming unit-erythroid (CFU-E), colony-forming unit-granulocyte/macrophage (CFU-GM) and colony-forming unit-pluripotent hemopoietic progenitor (CFU-Mix) in mice after PDS and PTS stimulation. RESULTS: Different concentration of PDS (2.5-200 micrograms/ml) could stimulate the proliferation of HPC obviously, showing increase of CFU-E, BFU-E, CFU-GM and CFU-Mix by 54.9 +/- 6.3%, 48.8 +/- 5.1%, 27.6 +/- 4.2% and 48.9 +/- 3.9% respectively, which was higher than that of the control group. While stimulated by PTS of the same concentration, the CFU-E and BFU-E was lower than that of control significantly (P < 0.05); when the terminal concentration of PTS was 200 micrograms/ml, CFU-E and BFU-E was zero respectively. In the CFU-GM culture, PTS in concentration of 12.5 micrograms/ml could cause the proliferation increased by 29.7 +/- 2.2% (P < 0.05), but in concentration of 100 micrograms/ml and 200 micrograms/ml, it showed inhibitory effect on CFU-GM, the inhibition rate being 48.6 +/- 3.9% and 100% respectively. CONCLUSION: PDS is the effective component of ginsenosides in stimulating proliferation of human bone marrow HPC. PTS is an component with inhibitory action on proliferation of CFU-E and BFU-E and its effect on CFU-GM was depending on its concentration.
