  • Title: Pulmonary antioxidant enzyme maturation in the fetal and neonatal rat. II. The influence of maternal iron supplements upon fetal lung catalase activity.
    Author: Tanswell AK, Freeman BA.
    Journal: Pediatr Res; 1984 Sep; 18(9):871-4. PubMed ID: 6483511.
    Abstract:
    It was observed that the lung catalase activity of premature (day 21 of gestation; term = 22 days) rat pups is affected by maternal iron intake. Pups from control dams receiving Purina Lab Chow and water ad libitum have only 50% of the lung catalase activity of pups from dams who received 1 mg/kg parenteral iron dextran daily from day 7 to day 20 of gestation. Other oxygen-protective enzymes, copper-zinc and manganese superoxide dismutase, glutathione peroxidase, and glucose-6-phosphate dehydrogenase, were unaffected by maternal iron supplements.
