Fig. 1. Effect of intrathecal administration of N -methyl-d-aspartate on isoflurane minimum alveolar concentration (MAC) in the saline- and PSD-95/SAP90 antisense oligodeoxyribonucleotide (AS ODN)–treated groups. Data are presented as mean ± SD, n = 5 animals for each group, except n = 14 for the saline-treated (control) group. **Significantly different from control (P < 0.01).
