近20年来,有关人奶中铁的含量各报告间不甚一致;50年代的正常值为0.6～1.3mg/l,60年代为0.6～1.0 mg/l,70年代为0.2～0.8 mg/l。因其采样的阶段不同,很难做出统一的评价。为了进一步观察不同哺乳阶段人奶内的含铁量,作者用火焰原子吸收光谱法,对27名身体健康、营养良好的城市哺乳妇女奶内含铁量进行了长期分析测定;自哺乳第2周开始,每隔1～2周测定一次,2个月后,每隔3～4周测定一次,每次均采集24小时的乳汁,在每次晨奶前及晨奶后取样,混合后进行分析,共检测229份样品。
The reports on iron in human milk have been inconsistent in the past 20 years; normal values in the 1950s ranged from 0.6 to 1.3 mg / l, from 0.6 to 1.0 mg / l in the 1960s and from 0.2 to 0.8 mg / l in the 1970s. Due to the different sampling stages, it is difficult to make a unified assessment. In order to further observe the iron content of human breast milk in different stages of lactation, the authors used flame atomic absorption spectrometry to analyze long-term iron content in milk of 27 healthy and well-nourished urban lactating women; from the second week of breast-feeding Beginning, once every 1 to 2 weeks, 2 months later, once every 3 to 4 weeks, each collecting 24 hours of milk, before each morning milk and morning milk after sampling, mixed analysis A total of 229 samples were tested.
