To investigate the therapeutic effects of angelica sinensis polysaccharide-iron complex （APIC） on hemolytic anemia and bone marrow injury in mice models. The hemolytic anemia mouse model was established by i.p. of phenylhydrazine （PHZ）. Changes of the indices including red blood cell count （RBC）, hemoglobin （Hb） and hematocrit （HCT） were determined by blood analyzer, and reticulocytes were observed by brilliant cresol blue staining during administration. Bone marrow injured mouse model was established by i.p. of cytoxan （CY） and chloramphenicol （CH）, and the therapeutic effect was observed by H-E staining. The indices of APIC treated groups with the medium and high doses were higher than those of the model group significantly. Moreover, the Hb and HCT were restored to the normal level after drug treatments. In addition, APIC can promote the proliferation and differentiation of reticulocytes obviously in the early stage of anemia mice, decrease adipose cell proliferation in bone marrow of injured mice and hasten the recuperation. In conclusion, APIC has therapeutic efficacy on hemolytic anemia and bone marrow injury caused by chemicals, which is reported for the first time.
