Abstract

Sickle erythrocytes and their membranes are susceptible to endogenous free-radical-mediated oxidative damage which correlates with the proportion of irreversibly sickled cells. The suppression of incubation-induced oxidative stress by antioxidants, free radical scavengers and an iron chelator suggest that oxidation products of membrane-bound haemoglobin contribute towards the pathology of the disease.

摘要

镰状红细胞及其细胞膜易受内源性自由基介导的氧化损伤,这种损伤与不可逆镰状细胞的比例相关。抗氧化剂、自由基清除剂和铁螯合剂对孵育诱导的氧化应激的抑制作用表明,膜结合血红蛋白的氧化产物促成了该疾病的病理过程。
