    Description / Table of Contents: Summary Following clotting factor assays were performed on the fluid of burn blisters of 11 patients with severe burns: Fibrinogen levels, Factor II, V, X and XIII, thrombin time, fibrin split products, plasminogen, antithrombin III, IgA, IgM, IgG, ethanol gelation test and total proteins. The results showed, that a quantity of Factor II, X and XIII, antithrombin III, plasminogen and IgG had left the circulation. On the contrary we found only small concentrations of Factor V, fibrinogen, IgM and IgA in the fluid of burn blisters. This distribution suggested that the losses of plasma proteins into the burn blisters were correlated to their concentration and their molecular weight. The decrease of plasma coagulation proteins during the first days after severe burns was probably partly due to losses through the walls of the vessels, because of the increased capillary permeability.
    Notes: Zusammenfassung Bei 11 Patienten werden folgende Untersuchungen des Brandblaseninhaltes durchgeführt: Fibrinogen, F.II, F.V, F.X und F.XIII, Fibrinogen-Fibrin-Spaltprodukte, Thrombinzeit, Plasminogen, Antithrombin III, IgA, IgM, IgG, Äthanol-Test und Gesamteiweiß. Die Ergebnisse zeigen, daß nach thermischem Trauma beträchtliche Mengen der Faktoren II, X und XIII, Antithrombin III, Plasminogen und IgG das Gefäßsystem verlassen, während F.V, Fibrinogen, IgM und IgA nur im geringen Ausmaß in der Blasenflüssigkeit nachweisbar sind. Nach diesem Verteilungsmuster der Brandblasenproteine muß angenommen werden, daß ihr Austritt aus dem Intravasalraum entsprechend ihrer Plasmakonzentration und Molekülgröße erfolgt. Der Abfall von Gerinnungsfaktoren bei Verbrennungspatienten in den ersten Tagen ihrer Erkrankung läßt sich somit zum Teil durch Verluste aus dem Gefäßsystem infolge der Permeabilitätssteigerung erklären.

    Notes: Abstract Failure of distinction between self and non-self is regarded a critical event in the pathogenesis of several human diseases such as systemic lupus erythematosus, rheumatoid arthritis, multiple sclerosis, myasthenia gravis, uveoretinitis or diabetes mellitus. Autoagressive immune reactions driven by activated autoreactive lymphocytes are a characteristic feature of these autoimmune diseases. The mechanisms by which the pathogenic control of autoreactive lymphocytes deviates from physiology can be studied in appropriate animal models under well-defined experimental conditions. Experimental models of autoimmune diseases in rodent inbred strains allow for the genetic mapping of susceptibility loci and might help to identify candidate genes also relevant to the pathogenesis of human diseases. Finally, the experimental models are valuable tools to develop rational immunotherapeutic strategies. Interesting features of some of the models employed for such research will be introduced in this review.

    Notes: Abstract An unprecedented arsenal of new xenobiotic immunosuppressive agents has been developed recently. Most of the new immunosuppressants have been tested primarily in the treatment of allograft rejection in experimental models of transplantation, and some of the new drugs have already proven their safety and efficiency in extensive clinical trials on transplant patients. Another field for their potential application is the treatment of autoimmune diseases. This review will give an overview of the therapeutic potential of the new xenobiotic drugs in different animal models of rheumatoid arthritis, systemic lupus erythematosus, myasthenia gravis, multiple sclerosis, diabetes mellitus, thyroiditis and uveoretinitis. The new xenobiotics are either inhibitors of the de novo synthesis of nucleotides, for example mycophenolate mofetil, mizoribine, leflunomide, and brequinar, or are immunophilin-binding agents (cyclosporin, FK506 and rapamycin) that inhibit signal transduction and cell cycle progression in lymphocytes. A different mode of action is likely to account for the immunosuppressive effects of deoxyspergualin, which may interfere with intracellular chaperoning by the heat shock protein HSP70 and the activation of transcription factor NF-kappa B.
