The apical epithelial surfaces of mammalian respiratory, gastrointestinal, and reproductive tracts are coated by mucus, a mixture of water, ions, glycoproteins, proteins, and lipids. The purpose of this study was to confirm the presence of mucin production using Haematoxylin and Eosin (H&E) stain as the gold standard and to describe the types of mucins produced in tumors of lung, colon and ovaries using various types of histochemical techniques. Methods: The resection specimens and biopsies from tumours of colon (n=16), ovaries (n=13) and lung (n=5) were included and stained with H&E to determin the histological diagnosis for selecting tissues with mucin production. Slides were stained with PAS, Alcian blue, High iron diamine-Alcian blue, Meyer’s mucicarmine and Alcian blue-PAS to demonstrate the mucin production and to identify types of mucins. Results: In the present study we observed predominance of acid mucins over neutral mucins. In addition in these cases we observed sulphomucin predominating over sialomucin. Conclusion: Mucin histochemistry can effectively determine the types of mucins. Keywords: Haematoxylin and Eosin; Periodic acid schiff; High iron Materials and Methods diamine; Alcian blue Paraffin embedded sections were prepared using automatic tissue Introduction processor, followed by preparation of paraffin block using our embedding station. -

ANATECH LTD INNOVATOR Special Stains Issue Special Stains Issue Hematoxylin and eosin (H & E) is the gold stan- dard for demonstration of tissue structure in anatomic pathology. However, by utilizing vari- ous dye solutions, special stains allow further visualization of major macromolecules (e.g., carbohydrates, proteins, minerals) in a rainbow of colors beyond the blue and pink hues of H & E staining.

457 Observations on a highly specific method for the histochemical detection of sulphated mucopolysaccharides, and its possible mechanisms By I. D. HEATH (From the Department of Anatomy, University of St. Andrews, Queen's College, Dundee. Present address: General Hospital, Nottingham) With 3 plates (figs, i to 3) Summary Whereas basic dyes in aqueous solutions stain chromatin, all mucins, mast cells, the ground substance of cartilage, and epidermis, it has been shown that a 0-03 % solution of basic dye in 5% aluminium sulphate produces a highly specific staining reaction for sulphated mucopolysaccharides. The best dyes are nuclear fast red (Herzberg) and methylene blue. Acid dyes in solutions of aluminium salts are induced to stain the ground substance of cartilage. These observations have been confirmed in a num- ber of species. Other metallic ions have similar properties and the use of green and purple chromic salts indicate that co-ordination plays a part in the reaction. Methylation, saponification, and sulphation experiments show that the sulphate group is essential. This has been confirmed by using pure chemical substances in gelatin models. Oxidation of keratin with performic acid, which produces sulphonic groups, causes hair (previously negative) to react. From this it is suggested that sul- phonic groups may also react, and that the reactive groups need not be attached to mucopolysaccharides. It is further suggested that the specificity of sulphated muco- polysaccharides is due to the fact that they are the only substances present in the tis- sues with a sufficient concentration of sulphate groups. Experiments with solochrome azurine show that the aluminium is attached to all tissue elements irrespective of their nature. -
