关于原发性再生障碍性贫血(简称:再障)的免疫学发病机理,已有人证实某些再障患者具有抑制细胞,它能在体外抑制正常人或自身粒、红细胞系克隆形成细胞生长,有的病人血清有抑制因子,能抑制体外粒系克隆形成细胞的生长等,用免疫抑制剂及体外ATG 处理病人淋巴细胞则上述抑制能力消失;用于治疗病人,则其血清抑制因子消失、血像及骨髓象恢复等。本文作者检测出再障患者血循环中有免疫复合物(IC)存在,从另一角度支持了再障的免疫学发病机理。
With regard to the immunological pathogenesis of primary aplastic anemia (abbreviation: aplastic anemia), it has been shown that some patients with aplastic anemia have inhibitory cells, which can inhibit normal human or autogenous granulocytes in vitro, clonogenic erythrocyte cell growth, Some patients with serum inhibitory factor, can inhibit the growth of granulocyte colony forming cells in vitro, with immunosuppressive agents and in vitro treatment of patients with ATG lymphocytes inhibit the above ability to disappear; for the treatment of patients, the serum inhibitory factor disappeared, blood Like bone marrow recovery and so on. The authors detected the presence of immune complexes (ICs) in the bloodstream of patients with aplastic anemia and from another perspective supported the immunological pathogenesis of aplastic anemia.
