Effects of anesthesia drugs on CAT activity in control and anesthetic groups. Values represent mean ± SEM of enzyme activity (unit/mg protein of hippocampal area). ^a p < 0.05 versus Xyl.-Ket. group. ^c p < 0.05 versus control and Ole.-Pro. groups. ^d p < 0.05 versus control, propofol, Ole.-Pro. and Ole.-Pro.-Ket. groups. Pro.-Ket. propofol-ketamine, Xyl.-Ket. xylazine-ketamine, Ole.-Pro. oleuropein-propofol, Ole.-Pro.-Ket. oleuropein-propofol-ketamine, Ole.-Xyl.-Ket. oleuropein-xylazine-ketamine (n = 8 rats per group)
