Abstract
Ascorbic acid concentrations in fetal human forebrain in the period 11 to 19 weeks' gestational age were 4 to 11 times higher than those of adults. Levels fell progressively with increasing gestational age but, in term babies dying within 4 weeks of birth, were still at least 3 times those of adults. It was confirmed that, in women delivering at term, ascorbic acid concentrations are approximately 4 times higher in cord blood plasma than in maternal blood plasma. The possible importance of ascorbic acid for normal human brain development is discussed.
摘要
孕龄11至19周的人类胎儿前脑抗坏血酸浓度比成年人高4至11倍。随着孕龄增加，其水平逐渐下降，但对于出生后4周内死亡的足月儿，该浓度仍至少是成年人的3倍。已证实，足月分娩的女性，脐带血血浆中的抗坏血酸浓度约为母血血浆中的4倍。本文讨论了抗坏血酸对人类正常脑发育的潜在重要性。
