844 Intrinsic Regulation of Glucose Output by Isolated Neonatal Pig Liver

Abstract

Fetal 'leaching' of maternal Cr has been suggested by scattered observations of elevated Cr levels in the term and unusually low Cr levels in the pre-term infant as well as by diminishing maternal Cr levels with increasing gestation and parity Available data suggest an inverse relation between Cr levels and glucose tolerance. This study represents an ongoing attempt to develop normative data on Cr in the perinatal period. AF Cr was measured in a graphite furnace (coeff. of var. 11%; recovery rate 95-105%) in 31 from 24 patients.
