The concentrations of retinol (vitamin A) were measured in 36 samples of human amniotic fluid obtained near term. Mothers with normal pregnancy had higher amniotic fluid retinol levels than patients with diabetes or toxemia. The results indicate that some maternal complications during pregnancy affect the transport of retinol into amniotic fluid, possibly due to reductions in the uteroplacental blood flow.
对接近足月时采集的36份人羊水样本中的视黄醇（维生素A）浓度进行了测量。正常妊娠的母亲羊水视黄醇水平高于糖尿病或毒血症患者。结果表明，孕期的一些母体并发症会影响视黄醇向羊水的转运，这可能是由于子宫胎盘血流量减少所致。
