采用计算机图像分析技术，对３０例再生障碍性贫血（ＡＡ）患者经补肾化瘀方药治疗前后的骨髓有核细胞进行ＤＮＡ含量测试分析，并与３０例健康人的测试结果比较，结果表明：ＡＡ患者治疗前骨髓有核细胞ＤＮＡ平均含量明显低于健康人（Ｐ＜０．０１），治疗后与健康人趋于同一水平。补肾化瘀方药影响ＤＮＡ含量的机理可能与改善骨髓微循环或（和）刺激造血细胞从而促进ＤＮＡ合成代谢有关。

英文摘要:

Quantification of myeloid cell-DNA in 30 cases with aplastic anemia(AA) was performed with computer image analysis techniquee pre-and post-treatmentally with Bushen Huayu recipe respectively,and compared with that of a control group of 30 healthy subjects.The results showed the average level of DNA in myeloid cells from AA patients was significantly lower than that of control(P<0.01)prior to the treatment and it raised to the same level approximately as that of control after the treatment.This change of DNA quantity might result from the improvement of microcirculation or(and) stimulus to hematopoietical cells which accelerated the DNA anabolism in these cells.
