新生儿黄疸不论从临床抑或实验均已证实,血清胆红素浓度过高可引起新生儿胆红素中毒性脑病,从而威胁新生儿生命,所以一直认为胆红素是潜在性毒性物质,以至于对新生儿高胆红素血症常采用各种方法以降低其血清浓度。但最近认识到胆红素有抗自由基的作用,保留血清中适量的胆红素可在一定程度弥补新生儿尤其是早产儿体内的抗自由基总能力的不足。1胆红素与胆绿素之间的转换血红素是血红蛋白组成成分,在血红素分解代谢 Neonatal jaundice in both clinical and experimental have confirmed that high concentrations of serum bilirubin can cause neonatal bilirubin toxic encephalopathy, which threaten the life of newborns, it has been that bilirubin is potentially toxic substances, so that Of neonatal hyperbilirubinemia often use a variety of methods to reduce its serum concentration. Recently, however, it has been recognized that bilirubin has an anti-free radical effect. Preserving the proper amount of bilirubin in serum can make up for the deficiency of the total anti-free radical capacity in neonates, especially premature infants. 1 conversion between bilirubin and bilirubin Hemoglobin is a component of hemoglobin, heme catabolism
