In newborns, the level of vitamin E in blood is very low as compared to that of placental intervillous blood and maternal blood. In our attempt to investigate the role of placenta in the transfer of vitamin E from the maternal to the newborn circulation, we have discovered that vitamin E is able to enter placental blood but is not being efficiently transferred from the placental to the newborn circulation. It appears from our preliminary study that the most limiting factor in the transfer of vitamin E from the placental to the newborn circulation is the transient deficiency of prebeta lipoprotein in the newborn blood at birth. A transient lipoprotein deficiency is implicated as a cause of low levels of vitamin E in the newborn.
与胎盘绒毛间隙血和母体血液相比，新生儿血液中的维生素E水平非常低。在我们试图研究胎盘在维生素E从母体循环转移到新生儿循环中的作用时，我们发现维生素E能够进入胎盘血液，但却不能有效地从胎盘转移到新生儿循环中。从我们的初步研究来看，维生素E从胎盘转移到新生儿循环中最具限制性的因素似乎是出生时新生儿血液中前β脂蛋白的短暂缺乏。短暂的脂蛋白缺乏被认为是新生儿维生素E水平低的一个原因。
