SOD1 and central nervous system cyst: It is interesting to note that in late FGR in newborns with IP (p = 0.04) and hyperbilirubinemia (p = 0.02), the 4-HNE expression was reduced, and in newborns with IVH and cerebral cysts, according to NSG data, the SOD1 (p = 0.04; p = 0.03) and SOD2 contents (p = 0.05; p = 0.05) were significantly reduced.
