为探讨塑料包埋骨髓切片对急性髓性白血病（ＡＭＬ）进行组织学分型的可能性，对７４例初诊ＡＭＬ患者的骨髓切片进行Ｒｏｍａｎｏｗｓｋｙ型染色的研究。结果４例属增生减退型，７０例为增生活跃型。３５例为白血性原始细胞的纯一性浸润型，３９例为非纯一性浸润型，７４例中４８例为纤维增生型，２６例为非纤维增生型ＡＭＬ。结果表明，在ＡＭＬ的分型中，活检切片对涂片起到补充与纠正作用。 To investigate the possibility of plastic-embedded bone marrow sections for histological classification of acute myeloid leukemia (AML), Romanowsky-type staining was performed on bone marrow sections of 74 newly diagnosed AML patients. Results Four cases were hypoplastic and 70 cases were hyperplasia. Thirty-five patients were purely infiltrated with white blood cells, 39 were non-pure infiltrating, 48 were fibrotic, and 26 were non-fibroplastic AML. The results showed that, in the classification of AML, biopsy slices complement and correct the smear.
