Human meconium has potent antioxidative properties

Area of Science:

• Biochemistry
• Neonatal Physiology

Background:

• Human meconium, the first infant stool, contains various compounds.
• Antioxidants play a crucial role in protecting against oxidative stress.

Purpose of the Study:

• To investigate the in vitro antioxidative capacity of human meconium.
• To compare meconium's antioxidant activity to known antioxidants.

Main Methods:

• Pooled and lyophilized human meconium was analyzed.
• Chemiluminescence assays were used to measure antioxidative capacity.
• Comparisons were made with vitamin C, a vitamin E analogue, and butylated hydroxytoluene.

Main Results:

• Meconium demonstrated significant superoxide trapping and peroxidation prevention.
• Meconium's capacity to trap peroxyl radicals was limited.
• Bilirubin and ubiquinol-10 were identified as potential contributors to meconium's antioxidant effects.

Conclusions:

• Human meconium possesses notable in vitro antioxidant capabilities.
• Bilirubin and ubiquinol-10 may mediate these effects.
• Meconium might function as an endogenous antioxidant during the perinatal period.
