慢性中性粒细胞性白血病(CNL)和慢性粒细胞性白血病(CML)同属于骨髓增殖性疾病群(MPD),但两者间有本质上的区别。本文作者用G带染色体检查法观察一例CNL患者骨髓细胞染色体,发现了迄今尚未报告的特殊核型并指出CNL与CML从细胞遗传学角度上看也是不同的疾病。本文患者(男,75岁)1981年3月因左侧肘关节骨折而入院就诊时得知白细胞数及
Chronic neutrophilic leukemia (CNL) and chronic myeloid leukemia (CML) belong to the group of myeloproliferative disorders (MPD), but there is an essential difference between the two. The authors used G-band chromosome examination to observe chromosomes of bone marrow cells from a patient with CNL and found so far not reported specific karyotypes and pointed out that CNL and CML are also different cytogenetic diseases. The patients (male, 75 years old) in March 1981 due to left elbow fracture and admission to the hospital informed of white blood cell count and
