ABSTRACT
OBJECTIVE: To study the blood enriching effect and mechanism of Jiuweiejiao ointment on mouse model of blood deficiency syndrome.METHODS: Blood deficiency syndrome model was established with cyclophosphamide(CTX) and acetylphenylhydrazine(APH). Total of 60 ICR mice were divided into normal group, model group, Siwu granule group, Jiuweiejiao ointment high-dose, medium-dose and low-dose group (15.6, 7.8, 3.9 g•kg-1). Each group mouse were treated with the respective drug through intragastrical administration once a day for consecutive 14 d. The levels of red blood cells (RBC), leukocytes (WBC), hemoglobin (HGB) level in blood of mice were detected by blood analyzer; the histopathological changes of bone marrow were determined by HE staining; the levels of erythropoietin (EPO), interleukin-3 (IL-3), tumor necrosis factor-α (TNF-α), granulocyte colony stimulating factor (G-CSF) and granulocyte-macrophage colony stimulating factor (GM-CSF) in serum were measured by enzyme linked immunosorbent assay (ELISA) method; the expression level of EPO protein in kidney tissue, G-CSF and GM-CSF protein in bone marrow tissue were detected by Western-blot method.RESULTS: Compared with model group, Jiuweiejiao ointment could significantly increase the levels of RBC, WBC and HGB in blood of mice, markedly improve bone marrow hyperplasia, reduce the non-hematopoietic tissue and adipocytes, obviously repaire the hematopoietic tissue structure; significantly decrease the level of TNF-α and increase the level of EPO, IL-3, G-CSF and GM-CSF in serum. In addition, Jiuweiejiao ointment could also obviously increase the expression of EPO protein in kidney tissue and G-CSF, GM-CSF protein in bone marrow tissue compared with that in model group.CONCLUSION: Jiuweiejiao ointment has obvious blood enriching effects, which may be related with promoting the secretion of hematopoietic growth factors and reducing the inhibition of hematopoietic function by negative hematopoietic factor.
