    Number of platelets adherent to exposed subendothelial surface 3 hours after carotid endarterectomy, comparing saratin-treated group (n = 7) and control group (n = 10). Data are means ± SE. Platelets were counted with scanning electron microscope. Saratin group received 5 μL of saratin solution applied topically to exposed subendothelial surface. Star indicates P value of .05.

    Electron micrograph (2000×) of endarterectomized rat carotid artery 3 hours after carotid endarterectomy. A, Control surface. B, Surface receiving topical saratin (5 μL). Control surface shows abundant cellular elements including fibrin strands, red blood cells, and platelets. Saratin-treated surface shows marked decrease in cellular elements.
