Fig. 4. Adhesion of platelets within the coronary system. Undergoing 20 min warm no-flow ischemia followed by 10 min reperfusion significantly increased the adhesion from control nonischemic conditions. Application of sevoflurane (Sevo) in a concentration of 1 minimum alveolar concentration (MAC) significantly reduced adhesion of platelets in postischemic hearts to near the level obtained under control conditions. Application of 0.5 MAC had no significant effect on platelet adhesion. *P < 0.05 I/R (group P) and I/R + Sevo 0.5 MAC (group Q) versus  Control groups (group G, H, and I) and sevoflurane 1.0 MAC (group R), respectively, I/R = ischemia-reperfusion.
