    Notes: Summary Using the monoclonal antibody Tü 300 we localized thromboxane synthase, a secondary enzyme of the arachidonic acid cascade, employing the alkaline phosphatase anti-alkaline phosphatase method and indirect double labelling immunofluorescence in frozen sections of human tissues. Aside from platelets, the source of the antigen, all cells of the mononuclear phagocytic system were positive, including epithelioid cells and associated giant cells, starry sky macrophages, dendritic cells of T-cell areas, Langerhans cells and Kupffer cells. In addition, some epithelial cells such as epithelia of tonsillar crypts, reticular epithelia of the thymic cortex and ductular epithelia in liver, pancreas, female breast and salivary glands showed occasional focal reactivity for thromboxane synthase. We suggest that the mAb Tü 300 is a key marker for the macrophage system and the thromboxane generating system in normal and pathological conditions. It may detect functional activities of as yet unknown significance in some specialized epithelial cells.

    Diagnostic tools for differentiating pleural mesothelioma from lung adenocarcinoma in paraffin embedded tissue (1993)

    Notes: Abstract A panel of 14 antibodies (panepithelial antibody Lu-5, anti-keratin-18, anti-keratin-7, Ber-EP4, anti-Leu-M1, HEA-125, anti-carcinoembryonic antigen, anti-blood group-related antigens A, B, H, B72.3, antiplacental alkaline phosphatase, anti-vimentin and BMA-120), which have been evaluated for use in differentiating mesothelioma from lung adenocarcinoma, was applied to a group of 24 suspected mesotheliomas. Using the established qualitative, descriptive criteria derived from monovariate statistical analysis of the tumour control groups (definite mesotheliomas, adenocarcinomas), a definitive allocation was possible in only 25% of suspected cases. We therefore constructed two “expert systems”, based on multivariate discriminant analysis with either the ALLOC 80 program for ordinal data or a newly developed analysis program for binomial data. With these two systems diagnostic allocation of suspected mesotheliomas was improved to 75% and 79%. The use of binomial data (“positive” versus “negative”) in conjunction with the probability-based test system is of particular interest because the primary data are easy to record and the test results have a higher statistical probability.

    Diagnostic tools for differentiating between pleural mesothelioma and lung adenocarcinoma in paraffin embedded tissue. Part I: immunohistochemical findings (1993)

    Notes: Abstract Specimens of 27 histologically definite mesotheliomas and 34 proven adenocarcinomas were examined with a panel of 14 antibodies: pan-epithelial antibody Lu-5, anti-keratin-18, anti-keratin-7, Ber-EP4, anti-Leu-M1, HEA-125, anti-carcino-embryonic antigen (CEA), anti-blood group-related antigens (anti-BGR A, B, H), B 72.3, anti-placental alkaline phosphatase (PLAP), anti-vimentin and BMA-120 used to determine their value in the differentiation between pleural mesothelioma and lung adenocarcinoma. Lu-5, anti-cytokeratin-7 and -18, B 72.3 and PLAP reacted in a high percentage of cases with both mesothelioma and adenocarcinoma. Anti-CEA and anti-Leu-Ml did not react with any of the 27 mesotheliomas tested but showed a reaction in 75% (anti-CEA) and 66% (anti-Leu-M1) of the lung adenocarcinomas. Seventeen percent of the adenocarcinomas and 96% of the mesotheliomas showed a positive reaction with anti-vimentin. Ber-EP4 was demonstrated in all lung adenocarcinomas, but only in 2 mesotheliomas in a focal manner (7%). HEA-125 and anti-BGR A, B, H reacted with 83% (HEA-125) and 75% (anti-BGR A, B, H) of the lung adenocarcinomas. The statistical parameters, sensitivity and efficiency were estimated and a normogram for judging the diagnostic power of a single antibody for the differential diagnosis of mesothelioma versus adenocarcinoma was developed. According to this, Ber-EP4, HEA-125, anti-BGR A, B, H and anti-CEA were, in descending order, the most powerful discriminatory antibodies.

    Cardiac myxomas: Immunohistochemical study of benign and malignant variants (1991)
    Springer

    Notes: Summary Immunohistochemical investigation of 11 cardiac myxomas (CMs) including one malignant metastasizing CM showed a co-expression of epithelial (lu-5 and CAM 5.2), mesenchymal (vimentin) and neuroendocrine antigens (neuron-specific enolase) in all tumour cells. Factor VIII was found in the endothelial cells of capillaries only. In the subendocardium of fetal heart tissue close to the foramen ovale myofibroblasts reacting with the panepithelial antibody lu-5 were detected. We conclude that CMs are neoplasms that may develop from embryonic cell remnants.
