...M. Rautenbach; K. Beyreiss Oral tolerance tests were performed with 2.0 and 3.0 g·kg –– 1 fructose and the fructose and glucose blood levels were observed in preterm and term newborns appropriate for gestational age (AGA) and small for gestational age (SGA). Their age ranged from 12 to 72 h...

...H. Přibylová; V. Melichar; V. Šabata Changes of total blood sugars, glucose, fructose, lactate, pyruvate, acid-base balance and free fatty acids were followed in 15 healthy newborns whose mothers received fructose infusions during labour. The results were compared with 20 control newborns...

... rate of deposition occurred between 100 and 107 days. The time of deposition of muscle glycogen was similar to that of the liver. Lung glycogen levels peaked between 70 and 90 days but then fell rapidly in late gestation. Cardiac levels were similar at all ages studied. Blood fructose levels were high...

...K. Beyreiss; M. Rautenbach Fructose turnover and utilization in dependence on age were examined in 55 pre-term and term newborns appropriate for gestational age during continuous intravenous infusion of fructose (0.25–1.0 g . kg –– 1 · h ––1 ). (1) The linear turnover range of fructose is exceeded...

...M. Rautenbach; K. Beyreiss Utilization, and total clearance of fructose were determined by methods of blood level kinetics in 40 preterm and term newborns appropriate and small for gestational age. In all groups the total clearance increases from 16.5 to 23.5 ml·kg –– 1 ·min ––1 at the age of 12–72...

...E.A. Brachet The sorbitol pathway was investigated in vitro on slices of umbilical cord tissue from normal full-term pregnancies. Glucose, sorbitol and fructose were shown to be present in this tissue at fairly constant levels. When added to the medium, these three substrates can be actively taken...
