Serum paraoxonase and arylesterase values as antioxidants in healthy premature infants at fasting and posprandial times

Abstract

OBJECTIVE: Newborn infants, particularly preterm infants, are at greater risk of oxidative stress because of an imbalance between high oxidant loads and immature antioxidant defenses. In several studies, the activities of serum paraoxonase (PON) and arylesterase (ARE) have been found to decline in patients under increased oxidative stress. We investigated the relationships between PON-1 and ARE with fasting and postprandial in premature newborns in this study.
