title: Influence of hirudin on the consumption of antithrombin III in experimental DIC.
abstract: The effect of hirudin and heparin on thrombin-induced consumption of antithrombin III, fibrinogen and platelets was studied in a rat model. Antithrombin III is consumed by tolerated thrombin doses by about 20 per cent. Hirudin and heparin ameliorate the consumption of fibrinogen and platelets at the low thrombin dose used. At high thrombin doses, tolerated only during simultaneous administration of exogenous inhibitors, heparin leads to markedly increased consumption of anti-thrombin III, whereas hirudin does not. With either kind of treatment, the thrombin effect on fibrinogen and platelets is inhibited, however, hirudin acts independently of a cofactor in contrast to heparin.
