Figure 2. Sequestration of polymorphonuclear neutrophils (PMNs) in the coronary system. Application of either isoflurane or sevoflurane in a concentration of 0.5 or 1 minimum alveolar concentration significantly reduced adhesion of PMNs in postischemic hearts to the level obtained under preischemic conditions. In the ischemia plus PMNs preischemic and ischemia plus PMNs postischemic groups, no anesthetics were applied. Data shown are means +/- SD (n = 6–10). *P < 0.05 versus the ischemia plus PMNs postischemic group.
