根据1979年10月全国血液病南宁会议制定的中枢神经系统白血病(CNSL)诊断标准。我们采用细胞沉降法原理,自制工具,使脑脊液(CSF)细胞自然沉淀于玻片上,然后染色镜检,取得了比较好的效果。对象与方法白血病88例(急淋48例、急粒11例,急单10例、粒单7例、多颗粒早幼粒4例、红白血病3例、慢粒2例、亚急粒2例、慢淋1例),淋巴瘤2例。男67例、女33例。年龄4～ According to the National Blood Disease Nanning Conference in 1979 October developed central nervous system leukemia (CNSL) diagnostic criteria. We use the principle of cell sedimentation method, homemade tools, so that CSF cells naturally precipitate on the slide, and then stained microscopy, and achieved good results. Subjects and Methods Leukemia in 88 cases (acute lymphocystosis 48 cases, 11 cases of acute, urgent orders 10 cases, 7 cases of single, multi-particle promyelocytic 4 cases, erythroleukemia in 3 cases, 2 cases of slow granules, subacute particles in 2 cases , 1 case of chronic leaching), 2 cases of lymphoma. 67 males and 33 females.
