The mean basal specific activity (S.A.) of the glutamic oxaloacetic transaminase of erythrocytes (EGOT) for a group of 64 pregnant women was lower (p less than 0.001) than the value for the cord bloods of newborn infants, and lower (p less than 0.001) than the value for adults who had a top limit of S.A. of EGOT. In establishing the top limit of the S.A., it is important that the mean basal S.A. of the cord bloods from 49 newborn infants was identical to the mean basal S.A. of adults who had an adequate supplement of pyridoxine. There were no differences in the mean basal S.A.'s of the cord bloods between asymptomatic mothers and mothers who had anemia, edema, hypertension, proteinuria and glucosuria. An infant may be born with a top limit of S.A. which is non-deficient in pyridoxal 5'-phosphate, but a mother can have a low level of the transaminase, and which is deficient in the coenzyme.
一组64名孕妇红细胞谷草转氨酶（EGOT）的平均基础比活性（S.A.）低于新生儿脐血的值（p<0.001），也低于EGOT比活性上限的成年人的值（p<0.001）。在确定比活性上限时，重要的是49名新生儿脐血的平均基础比活性与补充了足够吡哆醇的成年人的平均基础比活性相同。无症状母亲和患有贫血、水肿、高血压、蛋白尿和糖尿的母亲的脐血平均基础比活性没有差异。婴儿出生时比活性上限可能不缺乏磷酸吡哆醛，但母亲的转氨酶水平可能较低，且缺乏辅酶。
