Resveratrol protects against isoflurane-induced apoptosis of neuronal cells. The apoptotic rate was determined by (A) flow cytometry and (B) quantified. Groups: Control, control group; Ane, anesthesia-induced model group; Ane + Res (10), 10 µM resveratrol + anesthesia-induced model group; Ane + Res (100), 100 µM resveratrol + anesthesia-induced model group; Ane + Res (1,000), 1,000 µM resveratrol + anesthesia-induced model group. **P<0.01 compared with control group; ##P<0.01 compared with Ane model group.
