Ginseng is said to have beneficial effects on anemia. The proliferation effects of totalsaponins of Panax ginseng (TSPG) on hematopoietic progenitor cell in healthy individuals and 29 patientswith aplastic anemia (AA) were observed through bone marrow cultures of burst forming unit-erythroid(BFU-E) , colony forming unit-erythroid (CFU-E) and colony forming unit-granulocyte/macrophage (CFU-GM) in vitrcacompared with methyltestosterone (MT). The results suggest TSPG might prompt the prolif-eration of normal progenitor cellS at a concentration of 20 g/ml. The numbers of BFU-E ,CFU-E and CFU-GM increased by 37. 8±2.9 % , 31. 4±2. 9 % and 33. 3± 4. 0 % respectively over the controls ; further-more TSPG was still useful to BFU-E,CFU-E growth without Epo in vitro, although the colony nurnberswere much lower. Otherwise MT was useless to CFUGM. Of the 29 patients with AA, 14 who respondedto MT showed sensitivity to TSPG in marrow culture (the rising rate of colony formation exceeded 30 % ) ,but immune-mediated AA (patient's peripheral blood mononucleated cell suppressed normalhematopoiesis) and stem cell decreased AA (few of colonies were formed) showed almost no expressionfor TSPG activity because of the immunological suppression system and the absence of progenitors.
