再生障碍性贫血(简称再障)已知可由放射线、药物等化学物理因素引起,最近有一些关于肝炎后发生再障的报告,有的仍原因不明。曾经发现再障的骨髓细胞存在着增殖、分化、成熟及释放障碍,可是这些障碍的发病原理一直不大清楚。最近,有人认为再障的发生是与骨髓干细胞受损以及骨髓微环境改变有关。 Aplastic anemia (referred to as aplastic anemia) is known to be caused by chemical and physical factors such as radiation and drugs. There have been recent reports of aplastic anemia after hepatitis, and some remain unexplained. Bone marrow cells that have been found to have aplastic anemia proliferate, differentiate, mature and release obstacles, but the pathogenesis of these disorders has been unclear. Recently, some people think that the occurrence of aplastic anemia is related to bone marrow stem cell damage and bone marrow microenvironmental changes.
