Abstract
in English, Norwegian

The present experiments were performed to study the effects of a single high intravenous dose of Liquoid (10 mg/kg body weight) upon platelets, coagulation activities and hematocrit in blue foxes, and their correlation with the survival time. Both “short-living” (< 9 h) and “long-living” (24 h or more) blue foxes showed a marked consumption of coagulation factors, initial fall in fibrinogen, positive ethanol gel test and a gradual decrease in platelet counts. In addition “short-living” animals developed a marked rise in hematocrit, reflecting a considerable increase in vascular permeability. We conclude that activation of plasma proteases has as one of its effects increased permeability in microvasculatory vessels and that this may play a central role for the course and outcome of Liquoid-induced disseminated intravascular coagulation.

I denne artikkelen beskrives f oran dringen« i blodplatetall, koagu-lasjonsaktiviteter og hematokrit etter at en enkelt, høy dose, Liquoid (10 mg/kg) ble gitt intravenøst til blårev. Resultatene diskuteres i relasjon til dyrenes overlevelsestid etter injeksjonen. Råde dyr som d0de kort tid etter injeksjonen (< 9 t) og dyr som levde 24 t eller mer viste markert forbruk av koagulasjonsfaktorer, signifikant ned-gang i fibrinogen nivå, positiv ethanol-gel test og gradvis fall i blodplatetall. Rever som døde innen 9 t etter injeksjonen utviklet dessuten markert stigning i hematokrit umiddelbart før de døde, trolig som følge av økt karpermeabilitet. Vi konkluderer med at aktivering av plasma proteaser og økt karpermeabilitet er sentrale mekanismer ved utvikling av Liquoid indusert sjokk.
