Comparison of maternal and umbilical cord blood 15-isoprostane F2t, cadmium and nutrient antioxidant levels in vaginal delivered

Abstract

Oxidative stress is essentially an imbalance between the production of free radicals and the ability of the body to counteract or detoxify their harmful effects through neutralization by antioxidants.  Oxidative stress in cord blood is due to the changes that occur from a low oxygen pressure in utero to a high oxygen pressure at birth. The weight of the infant at birth is a powerful predictor of infant growth. The normal fetal growth is a result of complex interaction among the three components of maternal-placental-fetal unit. Maternal factors have an effect on the birth. Fetal and maternal oxidant stress is associated with adverse effects in LBW infants, and in this study we found increased mean of cord and maternal 15-isoprostane F2t in LBW –Term compared with  NBW-Term.
