Experimental venous thrombosis induced by homologous serum in the rat.
To investigate the effects of new drugs on the prevention of venous thrombosis, the Wessler stasis model is extensively employed usually in the rabbit. In this model, a hypercoagulable state is achieved by the administration of either heterologous serum (often human serum) or an activated coagulation factor followed by total stasis of the vein in which the thrombus is to be formed. Although classically the stasis model is performed in rabbits, it is possible to induce experimental venous thrombosis in a number of animal species, including rats. However, the use of homologous serum as the activating or thrombogenic agent has been previously described only in the dog and in the rabbit. The purpose of the present study was to compare the activities of heterologous and homologous serum as hypercoagulating agents in a rat stasis model of venous thrombosis using Wessler's technique. Heparin was employed as a reference antithrombotic compound in order to compare the two thrombogenic challenges.
