    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.

    Notes: A survey of 234 cases of pemphigus yielded three observations which suggest that different forms of pemphigus may have different etiologies.1. While the incidence of pemphigus in the age group of 21 and over was essentially the same in males and females (108 and 113) the incidence was significantly higher in females in the age group under 20. Only two of 13 patients in this group were males. Also pemphigus foliaceus and erythematosus was reported in a significantly higher proportion of the cases in the age group of 2 1/2 to 20 thus suggesting that the juvenile form of the discase differs from the adult form.2. In four of a group of 15 cases identified as pemphigus foliaceus the disease appeared to be provoked by minor physical insults, a frequency which is significantly higher than the five cases with similar histories in the group of 198 cases identified as pemphigus vulgaris.3. In the entire group of 234 cases two patients with pemphigus both proven by immunofluorescence had relatives with pemphigus. Also a third patient had a blood relative with bullous pemphigoid. This frequency of three per 234 is higher than would be expected by chance. Studies of one family (not included in this survey) with multiple skin antibodies suggest that such familial predispositions may be due to abnormal immune responses.

    Notes: Acantholysis occurring in rhesus monkey skin explants cultured on sera of 9 pemphigus patients was found to be largely dependent on the titre of intercellular antibody, and not on the participation of complement. Skin explants cultured on normal human sera and pemphigoid sera failed to give rise to intercellular staining or to develop lesions.Six of eight ‘negative’ pemphigus sera with intercellular antibody titres of less than 20 on skin (and titres ranging from 20 to 160 on monkey oesophagus) reacted with the skin explants as revealed by direct immunofluorescence with an anti-IgG conjugate. The binding of antibodies from 3 of these 6 reactive sera resulted in some pathological changes in the explants. At least two of these 3 ‘negative’ sera came from pemphigus patients with skin lesions.

    Notes: : A patient with the clinical features of dermatitis herpetiformis and the histological features of pemphigus, subcorneal dermatosis and dermatitis herpetiformis did not respond to treatment with pyridine or sulfones. Systemic steroids and azothioprine were effective. Immunofluorescence studies demonstrated circulating pemphigus antibodies and IgG bound in vivo in the intercellular spaces of the epidermis.

    Description / Table of Contents: Summary In casein-containing agarose gels, pepsin and chymosin form radial diffusion zones; the diameters of these zones show rectilinear correlations with the logarithm of the enzyme concentration at constant time. The sensitivity for both enzymes is below 1 μg. Addition of the inhibitor pepstatin A to these enzymes causes a reduction of the diameters of the diffusion zones, with large differences for both the enzymes. With this procedure, the pepsin/chymosin ratio in rennet preparations was assayed with an accuracy of ±5%. Identification of the inhibitors allows the determination of amounts in the namomole range. This method is a simple technique for the evaluation of proteinases and their inhibitors in screening systems.
    Notes: Zusammenfassung In caseinhaltigen Agarosegelen erzeugen sowohl Pepsin wie Chymosin radiale Diffusionszonen, deren Durchmesser bei gegebener Zeit dem Logarithmus der Enzymmenge proportional ist. Die Bestimmungsgrenze liegt für beide Enzyme unter 1 μg. Bei Zugabe des Inhibitors Pepstatin A zu den Proteinasepräparaten werden die Diffusionszonen beider Proteinasen verkleinert, aber in unterschiedlichem Ausmaße. Auf dieser Basis kann in technischen Labpräparaten das Mengenverhältnis Pepsin/Chymosin mit einer Genauigkeit von ±5% bestimmt werden. Bei Umkehr der Reaktion zum Nachweis des Inhibitors sind Mengen im Bereich von 10−9 Mol sicher erfaßbar. Die Methodik ist verallgemeinerungsfähig als Screening-Test für Proteinaseinhibitoren.

    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.
