| 3 | Effects of Astragalus polysaccharide on bone marrow and spleen progenitor cells in mitomycin—induced myelosuppresive mice显示文摘Astragalus polysaccharide(APS) is an extract of Astragalus membranaceus Var.mongolicus.The effects of APS on bone marrow and spleen progenitor cells in mitomycin (MMS)-induced myelosuppressive micr was observed.MMC7 mg·kg^-1 was injected ip on day 0,APS 100mg·kg^-1·d^-1 was given ac in 3 reginens (1)on day 0-4,(2)on day 0-11,(3)12 doses in 3 weeks.APS increased the number of bone marrow progeniter cells(CFU-C) of MMC treated micr 3-fold,from 1870±40 per femur to 6240±110 per femur on day3.APS treatment resulted in a higher level of bone marrow CFU-C at all time points from day 3 to day 18,in comparison with the control group.APS also significantly stimulated the proliferation of spleen pregenitor cells on day 14 (3-fold higher) and day 18(4-fold higher) after MMC treatment,although APS had no effect on spleen progenitor cells before day 14.These results demonstrate that APS enhances the proliferation and maturation of the progenitors of peripheral blood cells in MMC treated mice. | XiaX CuiYJ | 2002 | 中国药理学与毒理学杂志2002，16，6： | 0 |
