Insights
Radical-promoting iron was found in the plasma of children with kwashiorkor, suggesting free radical injury plays a role in this condition. This finding may lead to improved mortality rates through iron removal strategies.
Area of Science:
- Biochemistry
- Pediatric Nutrition
- Clinical Medicine
Background:
- Kwashiorkor is a severe form of malnutrition.
- Free radicals are implicated in various disease processes.
- Iron metabolism plays a critical role in cellular function.
Purpose of the Study:
- To investigate the presence of radical-promoting iron in children with kwashiorkor.
- To explore the potential role of free iron in the pathogenesis of kwashiorkor.
Main Methods:
- Utilized the bleomycin assay for quantifying free or loosely bound iron.
- Analyzed plasma samples from children with kwashiorkor, marasmus, and healthy controls.
Main Results:
- Non-protein-bound iron was detected in 58% of children with kwashiorkor.
- Free iron was absent in children with marasmus and healthy controls.
Conclusions:
- The presence of radical-promoting iron supports the hypothesis of free radical injury in kwashiorkor pathogenesis.
- Targeting and removing this free iron may potentially improve mortality in kwashiorkor patients.
Objectives:
To determine the presence of radical promoting iron (non-protein-bound or loosely bound or free iron) in the plasma of children with kwashiorkor.
Design:
The bleomycin assay was employed for the quantitation of free or loosely bound iron.
Setting:
The Red Cross War Memorial Children's Hospital, Cape Town, Tertiary Care.
Subjects:
Fifty children on admission with kwashiorkor: six with marasmus and twelve healthy well-nourished controls.
Results:
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.
Conclusions:
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.

Morphological Manifestations of Necrosis
Necrotic cells show different types of morphological appearance depending on the type of tissue and infection. In coagulative necrosis, cells become anucleated and die, but their...
Translation
Translation is the process of synthesizing proteins from the genetic information carried by messenger RNA (mRNA). Following transcription, it constitutes the final step in the expression of genes. This process is carried out by ribosomes, complexes of protein and specialized RNA molecules. Ribosomes, transfer RNA (tRNA), and other proteins produce a chain of amino acids—the polypeptide—as the end product of translation.
