In normal major and minor glands staining was localised to the ductal systems. There was no evidence of myoepithelial cell staining. The mucous elements of the submandibular and sublingual glands were negative, but in the mucous elements of the minor glands there was focal cytoplasmic positivity. There was no cytoplasmic staining of serous elements in major or minor salivary glands. In pleomorphic adenomas the luminal membrane of ductal elements was strongly positive, with focal cytoplasmic positivity in some myxoid areas. In mucoepidermoid tumours both adjacent cell membranes and cytoplasm were strongly positive. The ductal structure of adenoid cystic carcinomas were clearly delineated while the pseudoducts produced by enclosed areas of stroma were negative. All mesenchymally derived tumours were negative and a tumour previously considered as a chondroma was strongly positive. The results are discussed in relation to phenotypic heterogeneity and the histogenesis of salivary gland tumours.","PeriodicalId":76799,"journal":{"name":"Virchows Archiv.

Multinucleated giant cells and mononuclear round cells had similar activities of ACPase and non-specific esterase with a diffuse strong reaction. ATPase and 5'-nucleotidase reactions were strongly positive in the cytoplasm of multinucleated giant cells, and were seen not only in the cytoplasm but also on the cell membrane of round cells. The proliferating spindle cells in the malignant case were faintly positive for ACPase and non-specific esterase and were less positive for ATPase and 5'-nucleotidase on the cell membrane. The multinucleated giant cells and mononuclear round cells resembled histiocytes in the activities of 4 hydrolytic enzymes, and the multinucleated giant cells had enzyme activities similar to those of osteoclasts from new-born rat skull. The malignant giant cell tumor and cells in its tissue culture showed ALPase activity preferentially on the cell membrane of the spindle cells, and rarely on round cells or multinucleated giant cells. ALPase was resistant to heat treatment and was found to be the type IV isoenzyme by diffusion electrophoresis. The origin of the giant cell tumor of bone and the significance of the ALPase activity are discussed.","PeriodicalId":76799,"journal":{"name":"Virchows Archiv.

Ring-like AAT globules were found in the non-neoplastic cells in 12% of the cases of hepatoma and in 11% of the cases of cirrhosis. Atypical globules were seen in neoplastic cells in 5.4% of the cases of hepatoma and in 17% of the cases of liver cirrhosis. A diffuse fine granular pattern of AAT distribution was present in 31% of the cases of hepatoma in the neoplastic cells and in 27% of those in the non-neoplastic cells. The relatively high incidence of ring-like AAT-globules, and of atypical globules in cases of hepatoma and cirrhosis is not in agreement with the extremely low gene frequency of Z allele in a Greek population of patients with cirrhosis and hepatoma. Thus, there is some doubt whether AAT-globules in the liver represent a histopathologic marker of genetically determined AAT deficiency. A relationship between AAT deposits and the degree of differentiation of hepatoma was noted in this series. AAT-positive cells were found in 55% of moderately differentiated, in 29% of highly differentiated and in 20% of poorly differentiated hepatomas.","PeriodicalId":76799,"journal":{"name":"Virchows Archiv.
