[The fructose metabolism during the neonatal period and its relation to the concentration of bilirubin (author's transl)].

An enzymatic deficiency is the main reason of neonatal jaundice. It was the question, if there were other enzymatic restrictions of liver function in newborns. This investigation deals with the fructose metabolism in dependence of the concentration of bilirubin. No differences were found between unicteric and icteric newborns. Thus, one cannot suspect any diminution of the activity of the enzymes being necessary for fructose metabolism.
