流式细胞仪（ＦＣＭ）可以快速、准确地测定骨髓细胞ＤＮＡ含量，对骨髓细胞ＤＮＡ含量变化的分析，在研究小儿急性白血病发生及其治疗方面具有重要的临床意义。本文应用ＦＣＭ检测５４例常见血液病患儿骨髓单个核细胞（ＭＮＣ）的ＤＮＡ含量，以分析其倍体水平及细胞增殖周
Flow cytometry (FCM) can rapidly and accurately determine the DNA content of bone marrow cells, and analyze the changes of DNA content in bone marrow cells. It has important clinical significance in the study of the occurrence and treatment of childhood acute leukemia. In this paper, the DNA content of bone marrow mononuclear cells (MNCs) from 54 children with common hematological diseases was detected by FCM to analyze the relationship between their ploidy levels and cell proliferation weeks
