the relationship between two anticoagulant actions of glycosaminoglycans ( gags ) , namely the catalysis of thrombin inhibition ( assessed by thrombin-antithrombin-iii and thrombin-heparin-cofactor-ii formation ) and the inhibition of prothrombin activation , was explored by comparing the effects of heparin , heparan sulfate , and dermatan sulfate on the two reactions in plasma .
