Effect of Danggui Buxue Tang on immune-mediated aplastic anemia bone marrow proliferation mice.

To investigate the pharmacological effects of Danggui Buxue Tang (DBT) on immune-mediated aplasia anemia mice. The model of immune-mediated aplasia anemia mice was induced by means of (60)Co γ-ray irradiation and mixed cells of thymus and lymphnode of DBA/2 mice infusion through tail vein, the parameters tested indices were as following: blood picture, bone marrow nucleated cell count (BMNC), murine colony-forming unit-megakaryocytes (CFU-GM) of bone marrow cells, murine colony-forming unit-erthroid (CFU-E) and burst forming unit-erythroid (BFU-E). The results showed that DBT could not only withstand significantly decreation of blood cells by immune-mediated, but also stimulate on the growth of bone marrow colony cell and increase the weight of hemopoietic progenitor of bone marrow. Therefore, DBT had an obvious treat effect on immune-mediated aplasia anemia models mice.
