Serum antioxidant activity in premature babies.
Autooxidation of bovine-brain homogenate proved to be a good model to determine the antioxidant capacity of sera. It was measured in parallel with the level of ceruloplasmin and apotransferrin in sera of 35 healthy children and 20 premature babies (gestational age 28-33 weeks). Antioxidant capacity was very low in premature babies with a nadir on the 4th postnatal day. Lipid-peroxidation of bovine-brain homogenate could be inhibited in vitro by the addition of exogen antioxidant. In this assay MTDQ-DS, Cavinton, DPA-HC1, vitamin E, A, C showed different antioxidant activity.
