The effect of different levels of protein in he diets (15.1 +/- 0.3; 9.4 +/- 0.2; 8 +/- 0.4; 4.6 +/- 0.3 g nitrogen a day) on assimilation of amino acids in man was studied. The rates of endogenous excretion of 18 amino acids with feces were determined in the course of protein-free nutrition. It has been shown that as the body supply with protein decrease the assimilation of most amino acids rises. It has been proved experimentally that it is not wise using the index of "seeming" assimilation in determination of amino acid assimilation.
研究了不同蛋白质水平（每天15.1±0.3；9.4±0.2；8±0.4；4.6±0.3克氮）的饮食对人体氨基酸同化作用的影响。在无蛋白营养过程中测定了18种氨基酸随粪便的内源性排泄率。结果表明，随着机体蛋白质供应减少，大多数氨基酸的同化作用增强。实验证明，在测定氨基酸同化作用时使用“表观”同化指数是不明智的。
