Summary
Glomerular fibrin deposition, the hallmark of the Generalized Shwartzman Reaction, can be produced by a continuous infusion of a sublethal dose of endotoxin in rabbits and rats. The infusion of the active endotoxin into pregnant rabbits produced disseminated intravascular coagulation in a shorter time and quantitatively more pronounced than in the non-pregnant animal. Although the higher susceptibility of pregnant animals to endotoxin is well established, the infusion of an endotoxoid with little pyrogenic activity did not result in glomerular fibrin deposition, but a decrease in platelet number was noted. These data indicate that the endotoxoid has the cytotoxic activity of the original endotoxin molecule but the part of the molecule which induces fibrin deposition in the microcirculation is missing after the biochemical alteration.
Zusammenfassung
Glomeruläre Kbrinniederschläge, das Hauptmerkmal der generalisierten Shwartzman-Reaktion, kann bei Kaninchen und Ratten durch eine kontinuierliche intravenöse Infusion von Endotoxinen ausgelöst werden. Im Vergleich zu virginellen Kaninchen führte die Infusion von Endotoxin beim trächtigen Tier in einer kürzeren Zeit und quantitativ vermehrt zu Fibrinniederschlägen in der Niere. Dies weist erneut auf die stärkere Empfindlichkeit von trächtigen Tieren gegenüber Gerinnungsvorgängen hin. Die Infusion von Endotoxoid mit geringer pyrogener Aktivität resultierte nicht in glomerulären Fibrinniederschlägen, obwohl ein Abfall der Thrombozyten entstand. Die Ergebnisse deuten darauf hin, daß Endotoxoid eine ähnliche cytotoxische Aktivität auf Plättchen wie das Endotoxin ausübt, jedoch der Teil des Moleküls, der glomeruläre Fibrinniederschläge hervorruft, durch die biochemische Alteration verloren ging.
