    • Arterial and venous thrombosis were performed in pentobarbital-anesthetized male Sprague Dawley rats as described in: Schumacher, W. A.; .Heran, C. L.: Steinbacher, T. E. J. Cardiovas. Pharmacol. 1996, 28, 19. To measure ex vivo clotting time, rats were fasted overnight and anesthetized with sodium pentobarbital (50 mg/kg, ip). Catheters were placed in a jugular vein for iv dosing, and into the duodenum at the level of the bile duct for intraduodenal dosing. Arterial blood samples were withdrawn from a carotid artery catheter into 3.8% Na-citrate (1/10; v/v) to measure prothrombin time by the standard procedure described for Dade Thromboplastin-C reagent (Baxter Healthcare Corp., Miami, FL) (Baxter Healthcare Corp., Miami,FL), which had an international sensitivity index of 2.0 for the mechanical clot detection method employed. The dosing solution for these studies was 10% ethanol/90% PEG300 in a volume of 1 mL/kg for bolus iv or intraduodenal dosing, and at 1 mL/kg/h for sustaining iv infusion.
