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.展开更多

An Angelica sinensis polysaccharide-iron complex（APC） was prepared under the alkaline condition by adding a ferric chloride solution to the ASP solution. Then some identifiable properties of the complex were studied. The content of iron（ Ⅲ ） in the complex was determined with iodometry. The thermal property, the microscopic structure, the spectral characteristics, and N, C, H contents of the complex were examined by a variety of techniques including DSC, TEM, IR, NMR, and elemental analysis. The content of iron（ Ⅲ ） in the complex ranges from 10% to 40%. The DSC result shows that the melting point of the complex is about 450 ℃. The TEM result shows that the complex has an iron（ Ⅲ ） core（β-FeOOH core） linked by hydroxy and oxy bridges, with the polysaccharide chains attached to the surface of the core. The IR and NMR results also show that there is a β-FeOOH core in the complex. The elemental analysis shows that the contents of N, C, H in the complex are, respectively, lower than those of N, C, H in ASP. All our studies indicate that the APC consists of a β-FeOOH core surrounded by ASP.展开更多

Methods： The IDA rat model was established by adopting low-iron forage with a small amount of regular bloodletting. The rats were randomly divided into a model group, three AIPC groups （high, middle, and low dosage）, an Angelica sinensis polysaccharide （ASP） group, a mixture group （ASP＋FeCl3） and a positive control group （Niferex）. Changes in hemoglobin （Hb）, red blood cell count （RBC）, hematocrit （HCT） and iron content of whole blood were observed. Results： There was a significant difference before and after administration in all treated groups and all indices were restored to near-normal levels in the APIC groups and the positive control group. There was a significant difference among the changes of the indices in all the APIC groups and those of the model group but not between those of the APIC groups and the positive control group. However, the recovery of the indices in the APIC groups was superior to that in the positive control group. Conclusion： APIC not only has a superior therapeutic effect on IDA, but also has the effect of the ASP on supplementing blood and activating blood circulation. Hence, it may be used as a new iron-supplementing agent with a double therapeutic efficacy on blood supplementation for the treatment of IDA.展开更多
