从30名哺乳期妇女收集的3-d饮食组合物分析确定的总维生素和糖基化维生素B-6的平均饮食摄入量为8.63 ± 0.001。4.04和1.33 .+-。0.85μ mol/d（hivin × ±. SD）。包括或排除膳食糖基化维生素B-6含量的线性回归模型的比较表明，糖基化维生素B-6的摄入对母体血浆5“-磷酸吡哆醛浓度和母体尿液中总维生素B-6和4-吡哆酸排泄的影响很小（如果有的话）。根据文献中评价维生素B-6营养生化指标的指南，这些妇女似乎摄入了足够量的维生素。母乳中总维生素和糖基化维生素B-6的平均浓度分别为733和18 nmol/L。婴儿血浆吡哆醛5“-磷酸盐浓度为54 . ±. 44 nmol/L（hivin. SD），所有婴儿的身长和体重都与年龄相适应。
The mean dietary intakes of total and glycosylated vitamin B-6, determined from analysis of 3-d diet composites collected from 30 lactating women, were 8.63 .+-. 4.04 and 1.33 .+-. 0.85 .mu.mol/d (.hivin.x .+-. SD), respectively. A comparison of linear regression models that either included or excluded dietary glycosylated vitamin B-6 content indicates that the intake of glycosylated vitamin B-6 had little, if any, effect upon maternal plasma pyridoxal 5''-phosphate concentration and maternal urinary excretion of total vitamin B-6 and 4-pyridoxic acid. On the basis of guidelines from the literature for evaluating biochemical indices of vitamin B-6 nutriture, the women appeared to be consuming adequate amounts of the vitamin. The mean breast-milk concentrations of total and glycosylated vitamin B-6 were 733 and 18 nmol/L, respectively. Infant plasma pyridoxal 5''-phosphate concentration was 54 .+-. 44 nmol/L (.hivin.x .+-. SD) and all infants had lengths and weights appropriate for age.
