“…In agreement with the fi ndings of Hartman et al (14) on hair diameters of Negro children with protein calorie malnutrition, it could be considered that protein deficiencies might cause changes in the diameter of the hair, especially of coarse hair. From the results of our present study, W-group and R-group showed significant reductions of Lys, Thr, Cys, Met, Val, and Tie in essential amino acids and those of Asp, Ser, and Glu in non-essential amino acids.…”

“…Hartman et al (14) showed that hair diameter and cystine content in hair of Negro children with protein deficiencies were considerably decreased. As pointed out by Hartman et al (14), hair samples have been frequently used as a possible indicator, because hair is an easily accessible, continuously growing, high protein tissue.…”

“…As pointed out by Hartman et al (14), hair samples have been frequently used as a possible indicator, because hair is an easily accessible, continuously growing, high protein tissue. Koyanagi's studies on the effect of diet on cystine content of hair reported that changes in the cystine content of hair correlated closely with the consumption of animal protein (8,15).…”

SummaryWe examined hair properties from determinations of diam eter, amino acid composition, trace metal elements, and tensile strength of the hairs from protein-malnourished rats. The coarse or medium hair diameters of the experimental protein-malnourished rats had a tendency to decrease more than those of the control. Total contents of amino acids in the hairs had a tendency to decrease in the protein-deficient rats. Cystine content of rat hairs definitely decreased only in 5% wheat and 5% rice-pattern amino acid mixture diet groups but not in 5% gluten diet and 5% casein diet groups. And many of the low-protein diet groups were significantly lower in methionine content than the control except for the 5% casein diet group. The Mg, Zn, and Fe contents in the hairs considerably increased in protein-deficient rats against the control. Tensile strength of coarse hairs in the experimental protein-malnourished rats was significantly lower than that of the control. The changes in amino acid composition of rat hair proteins are more likely to be influenced by various qualities of dietary protein or different compositions of amino acid mixtures in the diets at a similar dietary protein level. It should seriously be considered from our data whether the reduced cystine content in the hair can be regarded as an indicator of nutritional status.

“…Hair cystine levels already reported on persons with "normal" protein nutritional status have varied in a wide range (4)(5)(6)(10)(11)(12)(13)(14)(15)(16)(17). This variation can be attributed to not only different "normal" conditions but also methodological differences for hair cystine analysis.…”

“…The hair is most likely to reflect small fluctuations because of the prev^iously mentioned high turnover rates, large protein requirements, and low protein priority (Bradfield tt al., 1967). For example, malnutrition has dramatic efFects on hair (Platt, 1965;Hartman et at., 1966); 0-08% of the dietary protein is contributed to man's hair growth (Goodwin, 1959). Haiiis the first tissue to be affected, when in malnutrition, protein is conserved for essential fimctions (Bradfield e.t al., 1967).…”
