In 14 studies, each lasting seven days, on eight bottle fed infants milk intake was measured by deuterium dilution and by weighing the formula consumed and oral losses. Mean (SD) milk intake was 829 (108) g/day when measured by isotope dilution and 837 (98) g/day when measured by direct weighing, giving a mean difference between methods of 1.0 (5.0)%. Thus the stable isotope procedure is a potentially useful method for investigating lactation and nutritional problems.
在14项为期7天的研究中,对8名人工喂养婴儿的牛奶摄入量通过氘稀释法以及称量摄入的配方奶和口腔流失量来进行测量。通过同位素稀释法测得的平均(标准差)牛奶摄入量为829(108)克/天,通过直接称量法测得的为837(98)克/天,两种方法的平均差异为1.0(5.0)%。因此,稳定同位素法是研究泌乳和营养问题的一种潜在有用方法。
