title: Effects of ligustrazine on hematopoiesis in the early phase of bone marrow transplantation mice.
abstract: To investigate the effects of Ligustrazine on histogenesis of bone marrow in the early phase of hematopoietic reconstruction in bone marrow transplantation (BMT) mice. The syngeneic BMT mice model was established. The syngeneic BMT mice were orally given 2 mg Ligustrazine twice a day. 1, 3, 5, 7, 10, 15 and 21 day(s) after BMT, peripheral blood granulocytes and bone marrow nucleated cells (BMNC) were counted and the diameter of central vein and the area of micro-vessel in femur were measured. The effect of Ligustrazine on hematopoietic stem cells was observed by colony forming unit of spleen (CFU-S). The effect of Ligustrazine on hemopoietic progenitors was studied by observing the number of progenitors of Granulocytes/Macrophage on day 10 and day 20 after BMT. In Ligustrazine-treated group, the diameter of center veins and the area of micro-vessel of femur were all significantly less than the control group 7, 10, 15, 21 days after BMT (P < 0.01). In addition, Ligustrazine significantly increased the number of CFU-S on day 10 and the number of CFU-GM on day 10, 20 after BMT. These results indicate that Ligustrazine can accelerate the histogenesis of hemopoietic bone marrow, which may be one mechanism by which Ligustrazine promotes hematopoietic reconstitution after BMT.
