ABSTRACT
To explore the effect of ligustrazine on the expression of adherent molecule VCAM-1/VLA-4 of bone marrow cells in syngenic bone marrow transplantation (BMT) mice, the mice were divided into 3 groups normal group (which received no treatment), BMT control group and ligustrazine-treated groups. BMT mouse models were established. The BMT control group and the ligustrazine-treated group were orally administered 0.2 ml saline per mouse and 2 mg ligustrazine per mouse, respectively, twice a day. On the day 7, 14, 21, 28 after BMT, mice were respectively killed. Bone marrow nucleated cells were detected, and then the expression of VCAM-1/VLA-4 was assayed by immunohistochemistry, RT-PCR and flow cytometry analysis, respectively. The results showed that in ligustrazine-treated group, the accounts of bone marrow nucleated cells on the day 7, 14, 21, 28 after BMT were all higher than that in BMT control group. The expression level in the ligustrazine-treated group was significantly higher than that in the BMT control group (P < 0.05 or P < 0.01). It is concluded that ligustrazine can enhance VCAM-1/VLA-4 expression in bone marrow after syngenic bone marrow transplantation in mice, which may be related to the mechanisms underlying the ligustrazine accelerating hematopoietic reconstitution in allogenic bone marrow transplantation.
