    Notizen: Abstract Immunohistochemical identification of carbonic anhydrase I and II (CA-I, CA-II) was made in human major salivary glands and obstructive adenitis in submandibular glands. Normal salivary glands stained the strongest for CA-II in serous acinar cells and were negative in mucous cells. Moderate to strong staining for CA-I and CA-II was found in ductal segments. Submandibular glands with obstructive adenitis exhibited reduced CA-1 activity in atrophic acinar cells, but not in ductal elements in the early and intermediate stages of the disorder. In the late stage of the obstructive lesion, CA staining in duct-like structures was moderate; however, almost degenerate ductal cells were negative for CA. During the progression of the degeneration in the obstructive lesion, the CA staining decreased dependent on acinar atrophy. Even after longstanding obstruction of the salivary gland, altered ductal epithelia may retain some of their functions.

    Notizen: Immunohistochemical detection of keratin proteins in duct-ligated submandibular glands (SMG) was carried out in mice and rats with or without testosterone administration. Keratin staining in normal salivary glands was limited to the striated duct (SD) and excretory duct (ED) cells and was usually lacking in granular convoluted tubule (GCT) cells. Following duct-ligation, the epithelia of intercalated ducts (ICD), degranulated tubules, duct-like structures, and dilated striated and excretory ducts showed positive keratin staining, usually in their luminal aspects. The concentration of keratin was proportional to the degree of degranulation of the GCT cells. The duct-ligated SMGs in animals with testosterone treatment showed a comparatively higher number of granules located in the GCT cells, and degranulation was slight. Keratin staining in hormone-treated duct-ligated glands also occurred in ductal segments to a slight degree. Keratin was also detected in degranulated tubules, and its concentration was increased in duct-like structures, whereas staining for EGF and NGF was decreased in degranulated tubules and lacking in duct-like structures.

    Notizen: Immunohistochemical detection of lactoforrin (LF), lysozyme (LZ) and carcinoembryonie 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 I.F, 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.

    Notizen: Lectin-binding profiles and keratin distribution in obstructive adenitis of human submandibular glands (SMGs) are reported and compared those of normal SMGs. Histologically, obstructive changes in the SMGs included acinar atrophy, duct-like structure formation in the early stage, and disappearance of acinar cells and dilation of ductal segments in the later, chronic stage. The following lectins were used: Con A (Glc. Man), PNA(Gal, GalNAc). RCA1I(Gal), DBA(GalNAc). SBA(Gal, Gal-NAc). UEA-1(α-L-Fuc) and WGA((GlcNAC, NeuNAc). Lectin staining in atrophie acinar cells was usually reduced except for SUA binding and was irregularly distributed in altered acinar and ductal epithelia. Binding of DBA and UEA-1 lectins were particularly intense along the luminar borders of ductal segments in the lesions. Immunohistochemically detectable keratins were characterized by intense staining in atrophie acinar cells and in all the ductal segments, whereas normal acinar cells, either serous or mucous, were negative.
