Fig. 3. The adhesion force per unit surface area developed between embolism bubbles and the vessel wall at different contact times using serum (control) or serum plus either Perftoran (PTN) or Pluronic F-127 (PF-127). Experimental conditions are with the endothelium intact ( A ), after air perfusion that followed surfactant exposure ( B ), and after air perfusion that preceded surfactant exposure ( C ). n = 4/group. * P < 0.05 compared with control at the same time point.
