ABSTRACT
Objective: To prepare a blood deficient model and study the effect of Tangkuei Blood Supplementing Decoction on hemopoiesis in this model. Methods: This model was made in mice by i.p. an accumulate doses of 60mg/kg acetylphenylhydrazine (APH) and 160mg/kg cyclophosphamidum (CY). The RBCs, WBCs, reticulocytes and bone marrow nucleated cells (BMNC) were counted, the micro structure of bone marrow was observed. The swimming time, the body temperature and the plasma cAMP, cGMP levels were measured. The effects of Tangkuei Blood Supplementing Decoction by p.o. administration on promoting the hemopioetic function were observed with the model mice. Results: Tangkuei Blood Supplementing Decoction could remarkably increase RBC, WBC, BMNC, improve the proportion of reticulolytes in peripheral blood and the micro struture of bone marrow, prolony the swimming time, raise the body temperature and the specific value of cAMP/cGMP. Conclusion: The model exhibits the main features of blood deficiency, and can be used as one of models of blood deficiency. Tangkuei Blood Supplementing Decoction can obviously improve the dual deficiention of qi and blood of model mice by supplementing qi and blood.
