    Description / Table of Contents: Zusammenfassung Immunofluorescenz(IF)-Untersuchungen mittels der Methode, die die Feststellung von Stratum corneum Antikörper im Serum und ihre in vivo-Fixierung ermöglicht, wurden bei 193 Psoriasis-Fällen und 89 Kontrollpersonen durchgeführt. Es wurde nachgewiesen, daß: 1. Im allgemeinen alle völlig entwickelten, aktiven Psoriasisläsionen IgG-Ablagerungen im Stratum corneum an den Antigenseiten, angeblich in Folge ihrer in vivo-Fixierung, enthalten. 2. In verschiedenen Psoriasisabarten waren die Antigenseiten des Stratum corneum völlig oder fast völlig von in vivo-fixierten IgG-Ablagerungen gesättigt, was man im Vergleich mit der Intensität der in vitro-Reaktion mit SC-Antikörpern aufzeigen konnte. 3. In der Mehrheit, aber nicht in allen Hautveränderungen waren die Komponente 3 und 5 des Komplements in vivo-fixiert und hatten ein gleiches IF Pattern wie IgG, besonders wenn man mehrere Biopsien in einzelnen Fällen durchführte. Eine teilweise oder komplette Sättigung konnte im Vergleich mit der Intensität der in vitro-Komplement-Reaktion festgestellt werden. 4. In allen Hautveränderungen mit typischem histologischem Bild von Psoriasis waren die IF-Befunde charakteristisch. Jedoch in manchen sehr frühen Psoriasisläsionen mit noch nicht gänzlich charakteristischem histologischem Bild wurden weder IgG noch Komplement festgestellt (in 2 von 17 Fällen).In zurücktretenden Läsionen waren schwache IgG-Ablagerungen nur in einzelnen Biopsien vorhanden und das Komplement war in der Regel nicht feststellbar. 5. In der Kontrollgruppe von 89 Fällen hatten nur einzelne Biopsien das psoriasis-ähnliche IF-Pattern, jedoch in ungefähr 30% der Biopsien wurden manche Ablagerungen im Stratum corneum festgestellt, obwohl sie ein unterschiedliches IF-Muster hatten.
    Notes: Summary Immunofluorescence (IF) studies using the test providing information on the reactivity of stratum corneum (SC) antibodies and their in vivo binding have been performed in 193 cases of psoriasis and 89 cases with other dermatoses. It has been shown that: 1. Essentially all fully developed, active psoriatic lesions had IgG deposits in the stratum corneum at the sites of the SC antigen, presumably due to in vivo binding of SC antibodies. 2. In various forms of psoriasis SC antigen sites appeared to be completely or almost completely satured with in vivo deposits of IgG as seen in tests with SC antibodies. 3. In most but not all lesions complement components C3 and/or C4 was found in a comparable pattern in the SC, especially when multiple specimens of single cases were studied. Partial or complete saturation of the SC antigen could be observed by the performance of complement indirect IF tests for SC antibodies in such specimens. 4. In lesions with typical histology of psoriasis the above-mentioned immunologic characteristics appeared to be a constant finding. However, in specimens of recent lesions which had not yet developed typical histology a proportion (2 of 17) were negative both for IgG and complement deposits. In receding lesions weak deposits of IgG were present only in a few specimens and complement deposits were as a rule negative. 5. cIn a group of 89 control specimens of other dermatoses only occasional cases gave the psoriasiform IF pattern, but about 30% of the specimens gave positive reactions in the SC though these were usually of a different pattern.

    Description / Table of Contents: Zusammenfassung Antikörper gegen Stratum corneum (SC) befinden sich in Seren aller Menschen und können mittels der indirekten Immunofluorescenzmethode festgestellt werden. In Psoriasis-Herden scheinen sie in vivo im Stratum corneum fixiert zu sein. Sie fixieren Komplement in vitro, was man durch Komplement-Fixierungs-Tests unter Benutzung von anti C4 oder anti C3 Konjugaten beweisen kann. IF-Teste mit unterschiedlichen Kontrollen haben aufgezeigt, daß Stratum corneum als Antigen in Psoriasis-Läsionen nicht nur von IgG, sondern in der Mehrheit der Veränderungen auch von Komplement umgeben ist. In völlig entwickelten Läsionen wurde das Komplement in 88% der Biopsien festgestellt, weniger häufig — in ungefähr 50% — in sehr frühen linearen Hautveränderungen vom Typ des zufälligen Köbnerschen Phänomens. Diese und frühere Beobachtungen erbrigen einen indirekten Beweis, daß Antikörper SC an der Entstehung der Psoriasisherde teilnehmen, und die Komplementfixierung hier von Bedeutung sein könnte.
    Notes: Summary The stratum corneum (SC) antibodies are present in all human sera as seen by indirect immunofluorescent (IF) staining. They appear to bind in vivo to the stratum corneum of psoriatic lesions. They fix complement in vitro in a two step complement IF test system using either anti C4 or anti C3 conjugates as indicators. IF tests with proper controls showed that the SC antigen in psoriatic scales is coated not only with IgG but in a majority of the lesions also with complement. In the present studies in fully developed lesions complement was detectable in 88% of the specimens studied and in about 50% of very fresh linear lesions of unintentional Köbner type. These as well as some previously published observations afford indirect evidence for the participation of SC antibodies and the ensuing fixation of complement in the development of psoriatic lesions.

    Description / Table of Contents: Zusammenfassung Untersuchungen der psoriatischen Hautveränderungen mittels der direkten und indirekten Immunofluorescenzmethode zeigen in der Hornschicht Immunoglobulin- und Komplementablagerungen auf. Das IF-Muster ist dasselbe wie bei der Bindung der im normalen Serum auftretenden anti-Stratum corneum-Antikörper an dem spezifischen Substrat, d.h. normaler Hornschicht. Die Bildung von Immunkomplexen zusammengesetzt von anti-Stratum corneum-Antikörpern scheint das Phänomen der «Squirting papilla» zu verursachen, wobei das normalerweise nicht zugängliche Stratum corneum unter der Einwirkung von Traumen oder Leukocyten-Proteinasen antigenisch wird. Die Proteinase-Produktion durch angeregte polymorphonukleare Leukocyten ist vermutlich ein wichtiger pathogenetischer Faktor in Psoriasis, wobei das Stratum corneum das Target ihrer Einwirkung ist und reaktiv (antigenisch) wird, was die in vivo-Fixation der Stratum corneum-Antikörper ermöglicht.
    Notes: Summary Immunofluorescence (IF) studies by the direct and indirect methods demonstrate immunoglobulins and complement bound in vivo in psoriatic scales. The IF pattern is comparable to that of stratum corneum antibodies (SCAb) bound in vitro on specific substrate, as visualized by the indirect IF method. Formation of immune complexes can be responsible for the “squirting papilla” phenomenon, and conversion of the stratum corneum — which is normally an inaccessible antigen — into its reactive form seems to be brought about by proteases of polymorphonuclear leukocytes. Stimulation of protease production by polymorphonuclears appears to be an important factor in the pathogenesis of psoriasis. The stratum corneum of the epidermis is probably the target, and becomes an antigen for SCAb present in the circulation.

    Notes: Summary Predictions derived from an information seeking, attribution model of false autonomic feedback were tested in an experiment using a 3 × 3 design. Male students (n = 61) viewed aversive slides accompanied by either increasing, constant, or no heart sounds. They were instructed either to attend to slides and sounds labelled extraneous, or to slides and sounds labelled as their own heart beats, or to try to explain their fictitious heart beats through slide features (attribution condition). Increase and constant feedback instigated equally intense information search (measured through self-determined viewing time and heart-rate deceleration) but increased feedback did not direct the search (measured through viewing time distribution and recall) more towards negative or less towards neutral features than did constant feedback. Increased feedback enhanced rated slide unpleasantness in the attention and attribution conditions whereas constant feedback decreased unpleasantness in the attribution condition only. Correlations were consistent with the hypothesis that attributions of fictitious autonomic reactions, but not information search and actual heart rate, mediate feedback effects on stimulus valences.
