探讨川芎嗪对免疫再生障碍性贫血(再障)小鼠骨髓细胞CD34抗原分子表达的影响。方法:建立免疫介导的再障小鼠模型, 6.0Gy~60Coγ-射线照射和尾静脉输注淋巴细胞造成小鼠再障。分为正常组、再障组(对照组)、川芎嗪组,除正常组外均胃饲川芎嗪注射液 4mg/次,1天 2次,第 10天用流式细胞仪检测各组小鼠骨髓细胞膜上 CD34抗原表达量。结果:川芎嗪 CD34抗原表达量的荧光强度(77.6±6.5)明显高于再障组(68.6±4.5,P<0.05),与正常组(80.0±2.6)比较无明显差异。结论:川芎嗪通过影响骨髓微环境促进免疫再障小鼠的造血干、祖细胞增生,增加CD34抗原分子的表达。 |
英文摘要: |
To explore the effect of ligustrazine on CD34 antigen expression of bone marrow cells in imrnunemediated aplastic anemia (AA)mice. Methods: The model of immune aplastic anemia mice was induced by means of 6.0Gy60Co γ-ray irradiation and lymphocyte infusion through tail vein. The mice were divided into 3 groups: the normal group, the AA control group and the ligustrazine group. Mice of the ligustrazine group were fed by 4 mg of ligustrazine injection twice a day by gastrogavage. On the 10th day, CD34 antigen expression intensity of bone marrow cell membrane was measured by flow cytometer analysis system. Results: CD34 antigen expression intensity of ligustrazine group was 77.6±6. 5, with no statistic difference from that in the normal group (80.0±2. 6), while that of the control group was much higher (68.6±4.5, P<0.05). Conclusions: Ligustrazine could promote proliferation of stem and progenitor cell of AA mice through influencing on bone marrow micro-environment so as to increase the CD34 antigen expression of bone marrow cells. |
