The effect of feeding a low-protein diet (1%) and its duration (4, 8, 12 and 16 weeks) on the protein content and amino-acid pattern of hair were studied. These changes were compared with control groups fed an adequate protein diet (16%). Protein content of hair was diminished in the protein-deficient rats after four weeks followed by a gradual decrease till the end of the experiment. Sulphur-containing amino acids, cystine and cysteine, were significantly reduced in the hair of the protein-deficient rats when compared with the normal controls. The amino-acid pattern showed significant differences from controls by the end of the whole experimental period.
研究了低蛋白饮食（1%）及其持续时间（4、8、12和16周）对毛发蛋白质含量和氨基酸模式的影响。将这些变化与喂食充足蛋白质饮食（16%）的对照组进行了比较。蛋白质缺乏的大鼠在四周后毛发蛋白质含量降低，随后逐渐下降直至实验结束。与正常对照组相比，蛋白质缺乏大鼠毛发中的含硫氨基酸胱氨酸和半胱氨酸显著减少。在整个实验期结束时，氨基酸模式与对照组相比显示出显著差异。
