红细胞系变化在白血病前期(简称“前期”)出现较频和较早,并有种种表现,可表现为再生障碍性贫血、阵发性睡眠性血红蛋白尿、铁粒幼细胞贫血、难治性贫血、获得性溶血性贫血、缺铁性贫血和恶性贫血等。本文拟就上述几种疾病时红细胞系的细胞学、生化学、细胞动力学等方面资料加以综合,并初步探讨其与白血病的关系。“前期”红细胞系造血障碍的形态学表现“前期”红细胞系造血障碍的主要临床表 Erythroid changes in the pre-leukemia (referred to as “early”) appear more frequently and earlier, and a variety of manifestations, can be manifested as aplastic anemia, paroxysmal nocturnal hemoglobinuria, Oocyte erythrocytic cell anemia, refractory anemia , Acquired hemolytic anemia, iron deficiency anemia and pernicious anemia. This article intends to synthesize the data of cytology, biochemistry and cell kinetics of erythrocytes in the above diseases, and to explore the relationship between them and leukemia.
