摘要

Objective:To investigate the changes in telomere length and the level of burst-forming units-erythrocyte(BFU-Es)and colony-forming unit-erythrocytes(CFU-Es)in mice with benzene-induced aplastic anemia(AA),and follow-up the therapeutic effects of Angelica Polysaccharide(AP).Methods:Male BALB/c mice(n=120)were randomly divided into three groups(1,2,3):normal control(n=24),AA control(n=48),and treated AA(n=48),respectively.Mice in Group 2 received benzene inhalation for 2.5 months and 1 ml distilled water p.o.per day for 2 weeks after the establishment of AA models.Similar procedure was applied to the mice in Group 3 and AP was given for 2 weeks after the establishment of AA models.Real-time polymerase chain reaction was used to survey relative telomere length measurement of the bone marrow cells.A BFU-Es and CFU-Es survey was done to follow-up the therapeutic effects of AP.Results:Compared with normal control,significant reductions of RBC,WBC,and platelet counts were found in peripheral blood of AA mice.After treatment with AP,counts of BFU-Es and CFU-Es were restored up to 66.8%and 77.25%,respectively,and length of telomere was restored up to 76.34%,of the normal levels.The telomere length in treated AA group was higher than the control AA group.Conclusion:The AP can protect the telomere length and differentiation of hemopoietic stem/progenitor cells,accelerate the recovery of BFU-Es and CFU-Es of AA mice,and then improve the bone marrow failure.
