Fig. 2. The recovery of force after simulated ischemia (SI) for trabeculae subjected to sevoflurane (SEVO) preconditioning. Recovery of force (Fdev,rec) is expressed as percentage of initial force (Fdev,start) for different groups. SI decreased Fdev,reccompared with time controls, which can be restored by preconditioning with sevoflurane. *P < 0.05 versus time control.
