Postnatal physiologic hypercholemia in both premature and full-term infants.
Previous studies have shown that bile salt concentrations in human blood taken from the placenta at birth of term infants are in the range found in adults. A 125I-radioimmunoassay procedure and capillary gas liquid chromatography-mass spectrometry have been used in this investigation to measure serum bile salt concentrations in premature and normal term infants. It was found that the serum bile...

Bronchopulmonary dysplasia (BPD) may adversely affect the postnatal growth of the extremely premature infant; however, most studies have not controlled for birth weight. We studied 90 Black premature infants (mean birth weight 989 +/- 148 g). Weight was recorded biweekly until discharge and at 4, 8, and 12 months of age corrected for prematurity. Infants with BPD (N = 23) were contrasted with i...

The critical maturation time of central otolith neurons in processing spatial orientations was examined in Sprague-Dawley rats. With the use of immuno-hybridization histochemical methods, we observed c-fos expression in vestibular nuclear neurons responding to transverse movement on the horizontal plane as early as P7 and those to antero-posterior stimulation as early as P9. In the inferior oli...
