(A). The movement track report of the elevated plus maze (EPM). (B-G) Histograms showing the behavioral parameters of the EPM test in the different experimental groups. The 40 and 60 min of exposed mice had significantly decreased in entry (B) and time spent (D) in the open arms relative to the control mice, while entry (C) and time spent (E) in closed arms were significantly increased. Compared to the 40-minute exposed mice, the 60-minute exposed mice had lower entrances (B) and time spent in the open arms (D). In 40 min, there were no significant changes in the number of head dippings (F) or rearing (G). However, a significant difference was observed in 60 min compared with the control mice. Results presented as Mean ± SEM (n = 10 mice in each group). ‘‘ns’’ indicates not significant (p > 0.05). (*) shows a statistically significant difference at the p < 0.05 level; (**) indicates a statistically significant difference at the p < 0.01 level; (***) indicates a statistically significant difference at the p < 0.001 level; (****) shows a statistically significant difference at the p < 0.0001 level.
