Objective:To observe the effect of oral administration of Astragalus membranaceus (AM)and arsenolite on arsenolite induced inhibition of blood and marrow cells in rats.Methods:Thirty two SD rats were randomly divided into 4 groups:group I (blank group),groupⅡ(10 mg/kg of arsenolite),group Ⅲ(arsenolite plus 7.6 g/kg of AM),and group IV(arsenolite plus 15.2g/kg of AM).Arsenolite or AM were taken orally once a day ,and the rats were bred in 8 successive weeks.Peripheral blood cells and hemoglobin contents,and cell cycle of marrow cells were measured by hemacytometer and flow cytometry,respectively.Results:(1)Erythrocytes and leucocytes were significantly higher in group Ⅰ,groups Ⅲ and Ⅳ,and group Ⅳ than those in groups Ⅱ and Ⅲ,group Ⅱ,and group Ⅲ,respectively( P <0.01).(2)Platelets and hemoglobin contents in groups Ⅰ,Ⅲ and Ⅳ were superior to those in group Ⅱ( P <0.01) (3)There were obvious differences in G1/G0 phase ratios between group Ⅰ and groups Ⅱ,Ⅲand Ⅳ( P <0.05),between group Ⅱ and groups Ⅲ and Ⅳ( P <0.01),and between group Ⅲ and group Ⅳ( P <0.01).(4)There were statistical differences in S phase ratios between group Ⅰ and group Ⅱ( P <0.01),and between group Ⅱ and groups Ⅲ and Ⅳ ( P <0.01).(5)There were statistical differences in G2/M phase ratios between group Ⅰ and groups Ⅱ and Ⅲ ( P <0.01),and between group Ⅱ and groups Ⅲ and Ⅳ ( P <0.01).Conclusion:AM improves arsenolite induced inhibition of blood and marrow cells in rats,so it could protect the hematopoietic system from arsenolite poisoning.
