Abstract
We have identified the biological active components, panaxadiol saponins components (PDS-C) isolated from Chinese ginseng extract with 92.44% in purity. In this article, the immune thrombocytopenia (ITP) BALB/c mouse was established. We used infusion of antiplatelet antibodies every other day, which was derived from serum of guinea pig immunized by the platelets of BALB/c mice. The platelet counts of ITP mice were steadily reduced and maintained at 20% to 30% of the normal level. The ITP mouse models were treated by PDS-C at lower, medium and higher dosages for 10 days. We observed that the peripheral blood platelet counts of ITP mice treated with PDS-C increased significantly in a dose-dependent manner, compared with untreated controls. PDS-C enhanced mature of megakarlocytes and increased their numbers, with a concomitant decease numbers of immature megakaryocytes in the bone marrow of PDS-C treated animals. In vitro assays, PDS-C promoted proliferation of megakaryocyte progenitor cells and increased colony forming unit- megakaryocyte (CFU-MK) colonies by 20.6% to 46.4% compared with untreated controls. Furthermore, the macrophage phagocytosis of exogenous red blood cells in the intra-abdominal cavity was inhibited by PDS-C treatment. This indicates that PDS-C could prevent platelet from attacking by exogenous antibody against platelet. In conclusion, our findings suggest that PDS-C may possess dual activities, namely that of promoting proliferation and differentiation of megakaryocyte progenitor cells, and that of regulating the immune function in the treatment of ITP mice.
