Histochemical studies of obstructive adenitis in human submandibular salivary glands. I. Immunohistochemical demonstration of lactoferrin, lysozyme and carcinoembryonic antigen.
Immunohistochemical detection of lactoferrin (LF), lysozyme (LZ) and carcinoembryonic antigen (CEA) was made in obstructive adenitis of the submandibular glands. Atrophic and altered acinar cells in the early stage of the lesion stained strongly for LF, whereas they were unreactive or stained slightly for LZ. Ductal cells usually stained for LZ. Staining for CEA was strong and irregularly distributed in altered acinar cells. Duct-like structures and dilated ductal segments in the chronic stage were generally negative for LF, LZ and CEA. Secretory components in luminal cavities gave abundant staining for LF, LZ and CEA. Histocytes which infiltrated into the connective tissue in the later stage showed a positive LZ reaction.
