Fig. 1. Effects of Pcer on the scopolamine-induced memory impairment in the passive avoidance test. Memory impairment was induced by scopolamine treatment (1 mg/kg, i.p.) in mice. At 60 min before acquisition trials, Pcer (5, 10, 20, 50 mg/kg) or saline was administered (p.o.) to mice. At 24 h after last acquisition trials, the retention trials were carried out for 5 min. Data were analyzed by one-way ANOVA for multiple comparison and Student-Newman- Keuls test as post hoc test. All values are expressed as mean ± S.E.M. from three independent experiments (n=6). #p<0.05 in comparison with control group, *p<0.05 in comparison with saline treated group.
