Fig. 2. The adhesion force per unit surface area developed between embolism bubbles and the vessel wall at different contact times with physiologic salt solution and intact endothelium (n = 3), with serum and intact endothelium (n = 6), and with serum and damaged endothelium (n = 4). *P < 0.05 compared with 10 min with physiologic salt solution and intact endothelium; #P < 0.05 compared with 10 min with serum and intact endothelium.
