Protective effect of gabexate mesilate against experimental disseminated intravascular coagulation in rats

Experimental disseminated intravascular coagulation (DIC) can be induced by 4 h sustained infusion of endotoxin at a dose of 100 mg/kg in rats. The experimental model of DIC in rats was used to study the preventive effect of gabexate mesilate (GM) against DIC. Before the infusion of endotoxin, 10(-6), 10(-3), 1, 10, 50 or 100 mg/kg of GM was injected intraperitoneally. The preventive effects against DIC were noted in all the parameters, such as fibrinogen and fibrin degradation products, fibrinogen level, prothrombin time, partial thromboplastin time, platelet count, and the number of renal glomeruli with fibrin thrombi, in rats treated with 1, 10 or 50 mg/kg of GM. From these results it was shown that GM inhibited the aggravation of endotoxin-induced experimental DIC in rats.
