Sickle cell disease (SCD) is characterized by malformed erythrocytes and results in many vascular complications, including the lysis of a minor proportion of these cells, liberating free hemoglobin, which is a potent scavenger of nitric oxide (NO). SCD involves inflammatory activation, including the upregulation of vascular coagulation. Because NO possesses important anti-coagulant and anti-adhesion properties, the increased scavenging of NO in SCD undoubtedly is a major contributor to the pathology of this disease.
镰状细胞病(SCD)的特征是红细胞畸形,并导致许多血管并发症,包括一小部分这类细胞的裂解,释放出游离血红蛋白,而游离血红蛋白是一种强大的一氧化氮(NO)清除剂。SCD涉及炎症激活,包括血管凝血的上调。由于NO具有重要的抗凝和抗黏附特性,SCD中NO清除增加无疑是该疾病病理的主要促成因素。
