Platelet adhesion on injured porcine arterial segments; A, ARC15105, Arc1779, and abciximab inhibited the adhesion of platelets radiolabeled with 111In on injured porcine arterial segments in perfusion flow chambers. Data are expressed as mean±SEM, n5, *P<0.05 versus control. B, Representative scanning electron microscopy micrographs of the platelet adhesion following exposure of whole blood to injured porcine arterial segments in perfusion flow chambers.
