34例白血病前期患者,符合FAB分类法中原始细胞过多性难治性贫血的诊断标准。24例伴有粒细胞减少,23例伴有血小板减少。骨髓增生活跃,原始及早幼粒细胞占粒系统的6-38%(其中12例≥12%)。初次诊断后,每例患者均作血象及骨髓象常规检查,~(59)Fe摄取率、骨髓粒系祖细胞(GM-CFU-C)培养及~(99m)Tc和~(111)In-转铁蛋白骨髓闪烁照相。骨髓闪烁照相的方法为:~(99m)Tc2mCi静注,20分钟后扫描,扫描终止后再注射~(111)In-转铁蛋白2mCi,48小时后作第二次扫描,按0、1、2、3级计算骨髓各部位放射活
34 cases of pre-leukemia patients, in line with the FAB classification of primitive cells in patients with refractory anemia diagnostic criteria. 24 cases with neutropenia, 23 cases with thrombocytopenia. Bone marrow hyperplasia, primitive and early promyelocytic accounting for 6-38% of the granular system (12 cases ≥ 12%). After initial diagnosis, the blood and bone marrow were routinely examined in each patient, and the uptake rate of ~ (59) Fe, GM-CFU-C and ~ (99m) Tc and ~ (111) Transferrin bone marrow scintigraphy. Bone marrow scintigraphy method: ~ (99m) Tc2mCi intravenous injection, 20 minutes after the scan, after the termination of the injection of ~ (111) In-transferrin 2mCi, 48 hours after the second scan, press 0,1, 2,3 levels calculated bone marrow radioactive
