Protective effects of Mul on As‐induced learning and memory impairment of mice in MWM. (a) Latency time of control, arsenic (As), mulberry (Mul), and arsenic plus mulberry (As+ Mul) were expressed as Mean ± SEM, where n = 7 for each group of mice. Mice were trained in three trials per day. ^*Significantly different from the control group at p < .05 in Welch's t‐test. ^#Significantly different from the control group at p < .05 in ordinary one‐way ANOVA. ^§Significantly different from the Arsenic (As) group at p < .05 in both Welch's t‐test and ordinary one‐way ANOVA. (b) MWM probe test for experimental mice. Time spent in the NE quadrant of control, arsenic (As), mulberry (Mul), and arsenic plus mulberry (As+Mul) mice groups were expressed as median (range) values, where n = 7 for each group of mice. The boxes and bars are as in Figure 1. Group comparisons were performed by Welch's t‐test (***p = .0002, ****p ˂ .0001) and ordinary one‐way ANOVA (p < .0001)
