Intravascular Coagulation in the Development of Massive Hepatic Necrosis Induced by Corynebacterium parvum and Endotoxin in Rats

Yamada S, Ogata I, Hirata K, Mochida S, TomiyaT, Fujiwara K. Intravascular coagulation in the development of massive hepatic necrosis induced by Corynebacterium parvum and endotoxin in rats. Scand J Gastroenterol 1989, 24, 293–298

When Escherichia coli endotoxin was intravenously injected into rats given killed Corynebacterium parvum 6 days previously, fibrin deposition and endothelial cell injury occurred in hepatic sinusoids at 1.5 h and were intensified thereafter. Serum alanine aminotransferase values were increased along with prothrombin time and decreased. plasrna levels of antithrombin III and coagulation factor VIII:C at 5 h. Antithrombin III concentrate (plus heparin) or superoxide dismutase infused concurrently with injection of endotoxin significantly attenuated the derangements of these variables and the histologic extent of liver injury at 5 h. Intravascular coagulation, probably developing through the action of superoxide anion, may contribute to the development of massive hepatic necrosis induced by C. parvum and endotoxin in rats.
