Kwashiorkor: an electron histochemical study of the hair shaft.

Abstract

Previous studies on hair in kwashiorkor have been equivocal regarding the normal or abnormal incorporation of amino acids into the hair shaft. In this study we have applied a sensitive electron histochemical technique to transverse sections of scalp hair from children with severe kwashiorkor in order to study its ultrastructure and the incorporation of sulphur-containing amino acids (cystine). We have found no evidence to support the idea that a protein deficient diet in the weaning or post-weaning period directly affects the distribution and relative amounts of sulphur-containing amino acids in the hair shaft in this disease.
