Effect comparison of different formulation of Dang-Gui-Bu-Xu-Tang on myelosuppression mouse.

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.

Experimental study of the bone marrow protective effect of a traditional Chinese compound preparation.

This study investigated the effect of Wei Gan Li on bone marrow haemopoiesis in myelosuppressed anaemic mice induced by (60)Cogamma, cyclophosphamide and chloramphenicol. After treatment with Wei Gan Li, colony forming units of granulocyte macrophages, erythroid cells, burst forming unit-erythroid cells, megakaryocytes and the proliferation of bone marrow stromal cells were measured by in vitro cell culture techniques. Bone marrow haemopoietic stem cells were measured by flow cytometry.

Effects of weiganli on the hemopoietic function of the myelosuppressed anemic mice.

Objective: To study the effect of weiganli ([Chinese characters: see text]) on bone marrow hemopoiesis.

Methods: The effects of weiganli on the peripheral blood picture and the number of bone marrow nucleated cells (BMCs) were observed in myelosuppressed anemic model mice, and the effects of weiganli on the growth of colony forming unit-granulocyte macrophage (CFU-GM), colony forming unit-erythroid (CFU-E), burst forming unit-erythroid (BFU-E), colony forming unit-megkaryocyte (CFU-Meg) were investigated by in vitro cell culture technique. The hemopoietic stem cells (HSCs, c-kit+) in bone marrow were double stained with fluorescent antibody PE-C-Kit and FITC-CD45, and the HSCs (c-kit+) were counted by flow cytometer with CD45/SSC (side scatter) gating.

[Effects of salidroside on bone marrow matrix metalloproteinases of bone marrow depressed anemic mice].

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.
