Zusammenfassung: Gegenstand und Ziel: Im Gegensatz zur Hündin liegen bei der Katze bisher wenige Studien über die genitale Keimflora geschlechtsgesunder Tiere vor. Ziel der Untersuchung war daher, physiologische Daten über die aerobe Vaginalflora bei dieser Spezies zu gewinnen. Material und Methoden: Für die vorliegende Studie standen 26 gesunde, anöstrische Katzen zur Verfügung, die zu einer Ovariohysterektomie vorgestellt wurden. Nach einer klinischen Untersuchung wurden von allen Probanden unter sterilen Bedingungen Vaginaltupfer entnommen. Ergebnisse: In allen Proben konnte ein Bakterienwachstum mit durchschnittlich zwei verschiedenen Bakterienspezies nachgewiesen werden. Die Gesamtkeimgehalte wurden bei 50% der Vaginaltupferproben als gering-, bei 15% als mittel- und bei 35% als hochgradig beurteilt. Vorherrschend waren Mischkulturen aus zwei bis vier verschiedenen Keimarten. Monokulturen wurden aus 38% der Tupferproben isoliert. Am häufigsten gelang der Nachweis von E. coli variatio haemolytica (E. coli var. haem.) (58%) und Staphylococcus epidermidis (42%). Als weitere Spezies wurden E. coli, α-, β-hämolysierende Streptokokken, anhämolysierende Streptokokken, aerobe Bazillen, Staphylococcus aureus, Staphylococcus intermedius, Pasteurella multocida sowie Klebsiellen isoliert. Auffällig ist die hohe Nachweisrate von E. coli var. haem. mit 35% in Mischkulturen und 23% in Reinkultur. Schlussfolgerungen: Die physiologische Mikroflora der felinen Vaginalschleimhaut differiert deutlich von der der anöstrischen Hündin. Besonders die Dominanz von E. coli var. haem. in 38% der Mischkulturen und 23% der Monokulturen bei der Katze ist hervorzuheben. Klinische Relevanz: Die vorliegenden Ergebnisse geben eine erste Grundlage für die Interpretation mikrobiologischer Befunde feliner Vaginaltupfer.

SummaryThe composition of the occlusive material within dilated glomerular capillaries, following intravenous injections of Liquoid in blue foxes, was studied electron microscopically; it was found that it mainly consisted of a debris in which disintegrated red cells constituted the major component. Damaged platelets and necrotic endothelial remnants were other components. These observations were interpreted as a result of glomerular stasis, and it was concluded that stasis in glomerular capillaries is a basic event in the development of the renal lesions accompanying the generalized Shwartzman reaction.

Shwartzman Reaction

SummaryThe role of Hageman factor in triggering intravascular coagulation has been studied in rabbits injected intravenously with Liquoid. Besides changes of coagulation parameters characteristic of consumption coagulopathy (e.g. decrease in platelet counts, fibrinogen levels, factor V activity), a pronounced drop in Hageman factor activity was observed after injection of Liquoid. Likewise, the partial thromboplastin time became prolonged.The activation of Hageman factor in vivo could be prevented by intravenous infusion of lysozyme. Twenty min after starting the lysozyme infusion, the partial thromboplastin time became prolonged from a mean of 29 sec to 108 sec. Animals infused with lysozyme and injected with a lethal dose of Liquoid did not develop a consumption coagulopathy. In the same manner, none of 10 animals treated with lysozyme developed the generalized Shwartzman reaction, whereas in the control group 19 out of 20 animals showed fibrin thrombi in the glomerular capillaries.From the present study it may be concluded that the intravascular coagulation process after intravenous injection of Liquoid is triggered by Hageman factor activation.

SummaryThe rôle of the clotting system in the pathogenesis of the generalized Shwartzman reaction (gSr) has been stressed in recent years. The clotting system is activated ubiquitously and as a result of it, fibrin is deposited intravascularly and a haemorrhagic diathesis develops. Evidence is presented herein, that endotoxin does not activate purified prothrombin, nor does endotoxin influence the convertion of prothrombin when it is activated in the presence of purified platelet-factor 3 (or caephalin) purified Ac-G (factor V) and Ca-ions.The trigger mechanism of the gSr also seems to be in the so-called prephase of clotting mechanism. Data are presented, which show that endotoxin activates the Hageman factor in vitro. The importance of this clotting factor and of platelet-factor 3 is discussed. Also the rôle played by the RES and cardiodynamic and vascular components are taken in consideration in the discussion.
