The pH of the stool and the amount of reducing substances present were observed in 51 normal neonates aged 5 to 8 days. A stool pH of 5 or less was found in 6, 4 of whom were exclusively breast fed. Reducing substances, 0-5% or more, were found in the stools of 16. Stool chromatography in 13 showed lactose, glucose, galactose, or a variable combination of these sugars--that is, a pattern consistent with lactose malabsorption. The stools of 3 infants contained oligosaccharides or maltose only. Chromatography of urine from 60 normal neonates showed detectable sugars in 11 but only 3 had levels above 50 mg/100 ml.
对51名5至8日龄的正常新生儿的粪便pH值和还原物质含量进行了观察。6名新生儿的粪便pH值为5或更低,其中4名是纯母乳喂养。16名新生儿的粪便中发现了0 - 5%或更高含量的还原物质。13名新生儿的粪便色谱分析显示含有乳糖、葡萄糖、半乳糖或这些糖的不同组合——即符合乳糖吸收不良的模式。3名婴儿的粪便仅含有低聚糖或麦芽糖。对60名正常新生儿的尿液进行色谱分析发现,11名新生儿的尿液中可检测到糖分,但只有3名新生儿的糖含量高于50mg/100ml。
