RESUMEN
OBJECTIVE@#To compare effect of different formulation of Dang-Gui-Bu-Xu-Tang(DGBXT) on myelosuppression mouse.@*METHODS@#HPLC was used to measure active ingredients of two DGBXT formulations. Hemopoesic function of bone marrow was measured by hemopoietic progenitor cell culture and peipheral blood count. And hemopoietic factors in bone marrow were tested by ELISA.@*RESULTS@#The content level of astragaloside A in granule formulation was higher than that in decoction and the content ratio of active ingredient was close to 5 : 1. Two DGBXD formulations could significantly improve amount of peripheral blood cells, and bone marrow cells of bone marrow suppression mice (P<0.05). DGBXD granule formulation significantly increased the colony quantity of all progenitor cell lines and amount of G(2)/M and S phase cells (P<0.05). It also significantly decreased amount of G(0)/G(1) phase cells in the bone marrow and was more effective (P<0.05).@*CONCLUSIONS@#DGBXT decoction and the granule formulation all can improve the hematopoietic function of bone marrow suppression mouse. They can improve quantities of peripheral blood and nucleated bone marrow cells, and yield of the hematopoietic stem/progenitor cells in vitro colony; balance the expression of cytokine (EPO, TPO and GM-CSF) in bone marrow microenvirement. They can also facilitate hematopoietic stem/progenitor cells to enter the cell cycle. And the effect of granule formulation is more satisfactory.

To examine the effect of salidroside on the expression and activities of matrix metalloproteinase-2 (MMP-2) and matrix metalloproteinase-9 (MMP-9) in bone marrow (BM) of BM depressed anemic mice by immunohistochemistry and gelatin zymography respectively, and to explore its roles in hematopoietic regulation. Immunohistochemistry showed that the expression of MMP-2 and MMP-9 of bone marrow cells (BMCs) was found in each group. Compared with control group, the expression of MMP-2 and MMP-9 was obviously increased in the model group, low-dose, middle-dose and high-dose salidroside. At day 4 after treatment of radiation and chemotherapy, the peak of the expression of MMP-2 and MMP-9 was found in middle-dose salidroside . At day 8 after treatment of radiation and chemotherapy, the peak of the expression of MMP-2 and MMP-9 was found in low-dose and middle-dose salidroside respectively. Gelatin zymography revealed that 66 kD proMMP-2, 62 kD MMP-2, 86 kD MMP-9 and 94 kD proMMP-9 were detected in control group, and the activity of MMP-9 was stronger among them. After treatment of radiation and chemotherapy, the activity of gelatinases of hemopoietic microenviroment (HM) was obviously decreased, but low-dose, middle-dose and high-dose salidroside could significantly increase the activities of proMMP-9 and MMP-9, attenuate the activity of proMMP-2. These results suggest that salidroside could promote the recovery of hematopoietic function of BM depressed anemic mice by increasing the expression and activity of MMPs, releasing the cytokines from ECM or cell membrane, repairing impaired microvessels of HM and promotion proliferation, migration and differentiation of HSCs.
