To investigate the effects of Angelica polysaccharide on erythrocyte immunity and marrow hematopoiesis in chickens, Angelica polysaccharide was used for the study of immunity and hematinic mechanism in order to provide basis for clinical reference. In this experiment, three gradient dosages (50, 100, 150 mg/kg body weight) of Angelica polysaccharide were drenched to the control group and the anemia groups, respectively. The anemia chickling model was made by abdominal injection of cyclophosphamide (CY) for 6 days (80 mg/kg•day). Red blood cell-C3b receptor (RBC-CR1) and red blood cell-immune complex (RBC-IC) rosette rates were measured and analyzed. Ectogenetic semi-solid culture medium of bone marrow hemopoietic progenitor cells was used to observe Angelica polysaccharide and separated serum from Angelica polysaccharide treatment on the proliferation of colony-forming unit-erythrocyte (CFU-E), burst-forming unit-erythrocyte (BFU-E) and colony-forming unit-granulocyte macrophage (CFU-GM). The results showed that Angelica polysaccharide can significantly increase RBC-CR1 rosette rate in the healthy chicken groups (p<0.01), but had no more effect on RBC-IC rosette rate (p>0.05). At the same time, Angelica polysaccharide can restore the RBC-CR1 rosette rate and the RBC-IC rosette rate caused by cyclophosphamide to the normal level. Serum containing Angelica polysaccharide can significantly facilitate the proliferation on CFU-E (p<0.01), BFU-E (p<0.01) and CFU-GM (p<0.01), but Angelica polysaccharide had no more direct proliferation on CFU-E, BFU-E and CFU-GM. This indicated that Angelica polysaccharide had the proliferation on hemopoietic progenitor cells of marrow by the change of hemopoietic factor.

scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
