Role of proteins in the feeding of low birth weight newborns is reviewed. After studies carried on 71 l.b.w. newborns fed with formulas from 2.75 to 5.3 grs./Kg./day of protein, several conclusions are obtained: some amino-acids no essential "per se" might have to be considered as so in the neonatal period. Under 3 grs./Kg./day biochemical findings are similar to those under malnutrition with proteic and caloric deficit. Over 3.8 grs./Kg./day hypertyrosinemias are frequent. With this offer, aminoacid indexes seem to be satisfactory, transferryn values are normal, increase in plasma proteins is significative, and renal overdosage of solutes is not high.
本文综述了蛋白质在低体重新生儿喂养中的作用。在对71名低体重新生儿进行研究后，这些新生儿以每天每千克体重2.75至5.3克蛋白质的配方奶喂养，得出了几个结论：一些“本身”非必需的氨基酸在新生儿期可能必须被视为必需氨基酸。每天每千克体重低于3克时，生化指标与蛋白质和热量缺乏的营养不良情况相似。每天每千克体重超过3.8克时，高酪氨酸血症很常见。在这种供给量下，氨基酸指标似乎令人满意，转铁蛋白值正常，血浆蛋白增加显著，肾脏溶质过量不高。
