  • Abstract
  • Look Inside

The histochemical property of colloid substance was studied in a case of colloid milium. Alcian blue and periodic acid Schiff reaction were used for staining mucopolysaccharides and glycoprotein and/or sugarcontaining compounds respectively. Mercuric bromphenol blue reaction was utilized for detection of basic proteins. In a further attempt to identify the various polyanions histochemically, staining was carried out with alcian blue containing different concentrations of electrolytes. Methylation, saponification and diastase, hyaluronidase and sialidase digestions were also employed. The results suggest that colloid substance in colloid milium consists of a sialic acid-containing mucopolysaccharide protein complex.
