摘要
Summary: Mice with immune induced aplastic anemia (AA) were given 5 mg ligustrazine intraperitoneally twice a day. On the 14th day, the expression of CD 49d , CD 49e , cyclinD 2 in bone marrow mononuclear cells (MNC) was examined by flow cytometry, and VCAM 1 on stromal cells was immunohistochemically measured by Strept Avidin Biotin Complex (SABC). The expression of CD 49d , CD 49e , VCAM 1 and cyclinD 2 in ligustrazine treated group was significantly higher than that in AA group ( P <0 01), but the ratio of G 0+G 1 phase cells was significantly lower than that in AA group ( P <0.01).The results showed that ligustrazine could improve the expression of adherent molecule and cyclin D 2 in the bone marrow of mice with immune induced aplastic anemia, thereby promoting the growth of hematopoietic cells.
