Abstract
Fetal lung lecithin metabolism was examined in rhesus monkey gestations complicated by glucose intolerance secondary to maternal streptozotocin (STZ) administration. Fetuses of STZ-treated mothers were delivered at 85% to 89% of term and were compared to two control groups of fetuses from normal pregnancies--one group age-matched to the STZ pregnancies, and the other composed of fetuses delivered in the final 10% of gestation. In the glucose-intolerant pregnancies, two measures of fetal lung lecithin biosynthesis--the amniotic fluid lecithin-to-sphingomyelin (L/S) ratio and the rate of 14C-choline incorporation into lecithin in fetal lung slices--were significantly greater than in age-matched normal gestations and were similar to results in late-gestation controls. However, lung lecithin concentrations in the glucose-intolerant group were comparable to the age-matched controls, and both were significantly less than in the late-gestation controls. Since the gestational age, mode of delivery, and fetal acid-base status were the same in the age-matched groups, we conclude that these changes in fetal lung lecithin metabolism are due to the effects of maternal glucose intolerance.
