本文检测34例急性白血病完整与破碎白血病细胞的促凝活性。26例急性非淋巴细胞白血病(ANLL)均无弥散性血管内凝血(DiC)依据,其完整白血病细胞的促凝活性增加,尤以M_5型为明显,而8例急性淋巴细胞白血病的完整白细胞均无促凝活性。破碎白血病细胞均无促凝活性。我们认为用细胞毒药物快速破坏白血病细胞仍是有效防止DIC的措施之一,若合用肝素可能更好。 In this paper, 34 cases of acute leukemia complete and broken leukemia cells procoagulant activity. Twenty-six cases of acute non-lymphocytic leukemia (ANLL) had no evidence of diffuse intravascular coagulation (DiC), and the procoagulant activity of whole leukemia cells was increased, especially in M_5 type. However, all of the 8 cases of acute lymphoblastic leukemia No procoagulant activity. Broken leukemia cells have no procoagulant activity. We believe that the rapid destruction of leukemic cells with cytotoxic drugs is still one of the effective measures to prevent DIC, if combined with heparin may be better.
