ABSTRACT

Objective To study the effect of iron overload on the bone marrow hematopoietic function on immuo-related pancytopenia(IRP)patients by hematopoietic progenitor cell(HPC)culture of bone marrow(BM).Methods BM liquid 4～5 mL was taken from 46 IRP patients of General Hospital Tianjin Medical University from July 2009 to February 2010 to detect colony-forming-unit of erythrocyte,blast-forming-unit of erythrocyte and colony-forming-unit of granulocyte-monocyteby HPC culture of BM.And according to the serum ferritin(SF)level,these patients were classified into 2 groups to compare HPC proliferation,blood cell counts,BM proliferation,blood transfusion and treatment effects.Results The mean values of 3 different colonies of IRP patients with high SF level [(43.33?17.74),(1.50?2.2),(11.06?5.83)/105BMMNC] were significantly lower than those of the patients with normal SF level [(77.43?40.64),(9.57?7.99),(21.25?11.41)/105BMMNC](P
