    Notizen: Summary The regional distribution of initial (i.e. most peripheral) lymph vessels of the human skin is unknown. New methods permit a precise systematic determination of the density of initial lymph vessels in every region of the dermis.Based on 202 skin specimens, it was possible to investigate the density of the lymph vessels of the skin derived from head. neck, upper arm. forearm, upper and lower leg. In all regions there seem to be a uniform structured dense subpapillary network and a wide meshed deep dermal network. The lymph vessels are at their most dense in the skin of the head.

    Notizen: The initial lymph vessels, the lymph capillaries and precollectors, are difficult to detect in normal skin using routine histological methods. A method is described in which specimens of the skin are fixed in an expanded condition. In 1.05 μm thick plastic-embedded sections the dilated lymph vessels of the skin can be demonstrated. The dermal lymph vessel network can be seen following the subepidermal injection of a coloured solution. The endothelial cells and subendothelial fibrous network can be examined using electron microscopy.

    Beschreibung / Inhaltsverzeichnis: Zusammenfassung Die hier durchgeführten Untersuchungen erfolgten an mononucleären Zellen von Patienten, die an einem frischen Schub einer Psoriasis vulgaris bzw. einer psoriatischen Erythrodermie litten. Die peripheren mononucleären Zellen wurden mit Hilfe einer Dichtegradientenzentrifugation isoliert und anschließend einer 6-Tage-Kultur mit Pokeweed-Mitogen (PWM), Concanavalin A (ConA), Methotrexat (MTX) und dem Retinoidabkömmling Ro-109359 inkubiert. Mit Hilfe des Plague-forming Assay nach Cunningham und Szenberg wurden die IgG-produzierenden Zellen quantifiziert. Als Zielantigene wurden Schafserythrocyten (SRBC) und Rindererythrocyten (BRBC) verwendet. Die Plaque-bildenden Zellen (PFC) von Psoriatikern konnten in der mit Mitogen stimulierten Kultur durch ConA, das normalerweise die Suppressorzellen stimuliert, nur um etwa 50% supprimiert werden, während die Zellen von gesunden Kontrollpersonen annähernd zu 100% supprimiert wurden. Ro-109359 wirkte stark reduzierend auf die IgG-PFC, während MTX sowohl IgG-wie IgM-produzierende Zellen verringerte. Diese hier mitgeteilten Ergebnisse legen es nahe, daß eine polyklonale Aktivierung von antikörperproduzierenden Zellen bei der Psoriasis vulgaris während der aktiven Phase besteht. Diese Antikörpersekretion wird durch Ro-109359 gehemmt. Mögliche Störungen der Immunantwort bei Psoriasiskranken, die wahrscheinlich auf einer verminderten Funktion der T-Suppressor-Zellen beruht, werden diskutiert.
    Notizen: Summary Isolated peripheral mononuclear cells of psoriasis patients with different disease characteristics, e. g. head-localised, quiescent guttata, confluent active widespread and erythrodermic, were cultured in a modified Mishell-Dutton system. Using the plaque-forming cell (PFC) assay, single cell antibody formation was studied, and class distribution monitored, adding pokeweed mitogen (PWM), concanavalin A (ConA), methotrexate (MTX) or Ro-109359/31, as well as autologous sera to the culture. PFC-estimation vs. sheep red blood cells (SRBC) and burro red blood cells (BRBC) revealed a distinct suppression of primarily IgG-PFC in some of the PWM-treated patients' cultures; ConA maximally reduced PFC by only 50%, compared to 100% for normal immune cells. Ro-109359/31 reduced mainly IgG-PFC in the co-cultures with PWM or autologous sera. MTX resulted in a reduction of IgG-PFC and IgM-PFC equally. The results were compared with cultured immune cells from normal individuals. The two antigenically different indicators, the partial abolition of ConA induced suppression, broad-based immunoglobulin elevation in the sera, and the mainly IgG-formation hint at the role of polyclonal B-cell activation in the perpetuation of psoriasis, which can be specifically reduced by Ro-109359/31. Suppressor cell dysfunctions remain to be discussed.

    Notizen: Summary Two new methods now allow the systematic examination of the morphology and micropathology of the initial lymphatics (lymph sinuses and precollectors) in human skin biopsy specimens under the scanning electron microscope. Pertinent studies and findings in the intact skin of anesthetized pigs demonstrate the standard quality of the biopsy preparations. The following are new findings made with these methods: in the skin of the human head, both the lymph sinuses and the precollectors extend as far as the epidermis. The opening apparatus of these vessels consists not only of anchoring filaments and interendothelial openings, but also of endothelial bridges and trabeculae. The interendothelial openings can be present in three types of transformation (Type I–III). As part of these studies, an attempt was made to standardize the lymphological nomenclature so that it would be acceptable to both anatomists and clinicians.

    Notizen: Summary Initial lymphatic vessels (IL) are difficult to demonstrate histologically in excised normal skin, as they are usually completely collapsed. In this report three different methods (vacuum extension, large traction extension, and small traction extension) are described by which human skin specimens can be mechanically extended. After extension specimens were Epon enbedded and the IL counted and their diameters measured. The greatest number of lymphatic vessels was found in specimens extended by vacuum, and the smallest number in small specimens extended by traction. The highest density of lymphatic vessels was found 50–300 Μm below the epidermis. Our data reveal that vacuum extension is useful for investigating questions concerning the topography of IL, whereas preparations extended by traction are more suitable for obtaining information about single lymphatic vessels.

    Notizen: Summary Fifteen patients with Sneddon's syndrome presenting since 1979 were re-examined. After a neurological examination, an orienting test of mental ability as well as an electroencephalogram were performed in all patients. In 10 of the 15 patients computed tomography of the brain was performed, too. Preceding reports and the results of the present study have been used to discuss the characteristics and prognosis of Sneddon's syndrome.
