[Lipid peroxidation and the antioxidant system in newborn infants]

During measurements of the content of malonic dialdehyde and the total antioxidant activity in blood plasma and red blood cells as well as of their peroxide resistance in healthy neonates, it has been established that in boys and girls the majority of the study parameters did not differ within the first 6 days of life. At the same time in girls, catalase and peroxidase of red blood cells were activated and the total antioxidant activity of blood plasma was increased since the first days after the birth.
