title: [Comparative histochemical study of glycoconjugates of the major salivary glands and pancreas in humans].
abstract: The human parotid, submandibular, sublingual salivary glands and pancreas have been studied with lectin--horseradish peroxidase conjugates (con A, PNA, SBA, WGA, LAL), aldehyde fuchsin and Bismark brown. Intercalated duct cells produce a specific aldehyde-fuchsin-reactive substance. These cells are found only in the submandibular and parotid, but not in the sublingual glands. Similar reactivity is found in B-insulocytes of the pancreas. Aldehyde-fuchsin marks cytoplasmic granularity of the striated duct cells of all large salivary glands. This specific granularity is also selectively stained with Bismark brown and con A. Using fucose-specific lectin from Laburum anagyroides bark (LAL), granularity in serocytes of the submandibular gland is demonstrated. Some individual variations are observed in PNA binding to serocytes of the submandibular gland. It reveals that thyroglobulin-peroxidase conjugate (previously reported as an available second-step reagent for indirect lectin histochemical methods) non-specifically binds to the striated duct cells of the submandibular gland. During control staining it is also found, that DAB-reaction for endogenous peroxidase can be used as a test-system for a selective histochemical exposure of nuclear regions of endotheliocytes, pericytes and striated duct epitheliocytes of the human salivary glands. Possible significance of the phenomena observed is discussed.
