Figure 4.

The effect of chronic Celastrus paniculatus oil treatment on performance of a partially baited task in 8-arm radial maze in different groups. (a) The acquisition (percentage correct choice) of the radial arm maze task across trials; (b) performance in block 7 and 8 (percentage correct choice). Data are represented as mean ± standard error of the mean. NC: Normal control (n = 14). ST: Rats subjected to restraint stress for 21 days (6 h/day) (n = 8). ST + VE (n = 8), ST + CP-400 (n = 8), and ST + CP-600 (n = 8): Stressed rats subjected to 14 days of treatment with vehicle, Celastrus paniculatus 400 or 600 mg/kg, intraperitoneally, respectively. One-way ANOVA followed by Tukey's post hoc test. ***P < 0.001 normal versus stress. ###P < 0.001 stress versus stress + drug treatment
