摘　　要：目的：探讨复方活血汤（简称中药）对免疫诱导的再生障碍性贫血（再障）小鼠骨髓造血细胞粘附分子及细胞周期蛋白表达的作用。方法：建立免疫诱导的再障小鼠模型，喂饲１００％复方活血汤每次０２ｍｌ，每日２次，第１３日用流式细胞仪检测小鼠骨髓单个核细胞β１整合素家族（ＣＤ４９ｄ／ＣＤ２９，α４β１；又称ＶｅｒｙＬａｔｅＡｎｔｉｇｅｎｓ，ＶＬＡ家族）及细胞周期蛋白Ｄ２的表达水平。结果：中药组ＣＤ４９ｄ表达明显高于再障组（Ｐ＜００５），且与正常组无明显差异；中药组细胞周期蛋白Ｄ２表达明显高于再障组（Ｐ＜００１）；而其Ｇ０＋Ｇ１期细胞数显著低于再障组（Ｐ＜００１）。结论：复方活血汤能增强免疫再障小鼠骨髓造血细胞粘附分子ＣＤ４９ｄ和细胞周期蛋白Ｄ２的表达，促进造血细胞的增生。Objective: To study the effect of composite blood activating decoction (CBAD) on expression of adherent molecule CD 49 d and cyclin D 2 in bone marrow hematopoietic cells in experimental immune mediated aplastic anemia (AA) mice. Methods: After the model of AA was established, the animals were fed with 0.2ml of 100% CBAD, twice a day for 12 days. Te CD 49 d and cyclin D 2 expression level of bone marrow hematopoietic cells in model mice were measured by flow cytometor analysis system at the 13th day of experiment. Results: CD 49 d expression level in CBAD group was significantly higher than that in the AA group (P<0 05), and was similar to that in the normal group (P>0 05). The expression of cyclin D 2 in CBAD group was significantly higher than that in the AA group (P<0 01), but the cell count of G 0+G 1 phase was significantly lower in the CBAD group, as compared with the AA group, P<0 01. Conclusion: CBAD can increase the expression of adherent molecule CD 49 d and cyclin D 2 in bone marrow hematopoietic cells, and promote the growth of hematopoietic cells.
