To determine the presence of radical promoting iron (non-protein-bound or loosely bound or free iron) in the plasma of children with kwashiorkor.
The bleomycin assay was employed for the quantitation of free or loosely bound iron.
The Red Cross War Memorial Children's Hospital, Cape Town, Tertiary Care.
Fifty children on admission with kwashiorkor: six with marasmus and twelve healthy well-nourished controls.
Non-protein-bound iron was detected in the plasma of 58% of children with kwashiorkor but was absent in marasmic and healthy well-nourished children.
The presence of radical promoting iron supports the hypothesis that a free radical injury probably plays a role in the pathogenesis of kwashiorkor and its removal may improve mortality.
确定夸休可尔症患儿血浆中促自由基生成铁(非蛋白结合铁或松散结合铁或游离铁)的存在情况。
采用博来霉素测定法对游离或松散结合铁进行定量。
开普敦红十字战争纪念儿童医院,三级医疗中心。
50名入院的夸休可尔症患儿、6名消瘦症患儿和12名营养良好的健康对照儿童。
58%的夸休可尔症患儿血浆中检测到非蛋白结合铁,而消瘦症患儿和营养良好的健康儿童血浆中未检测到。
促自由基生成铁的存在支持了以下假说,即自由基损伤可能在夸休可尔症的发病机制中起作用,清除这种铁可能会降低死亡率。
