Fig. 9. Numbers of black dots labeled by TUNEL staining with 8% desflurane (Des), 3% sevoflurane (Sevo), 2% isoflurane (Iso), and control (Cont) group for 6 h (n = 5 mice for each group) were counted in the several regions. CA1 = hippocampal CA1 region; CA3 = hippocampal CA3 region; DG = dentate gyrus; DHC = dorsal hippocampal commissure; Amg = amygdala; CP = caudate/putamen; Th = thalamus; RSC = retrosplenial cortex; II = cortex layer 2 in parietal cortex; IV = cortex layer 4 in sensory cortex. Comparisons of means of each group were performed using a one-way ANOVA followed by Neuman-Keuls multiple comparison post hoc test. F and P values are presented below each panel. *P < 0.05, **P < 0.01, or ***P < 0.001 compared with controls. #P < 0.05, ##P < 0.01, or ###P < 0.001.
