**5.15 Comparison of the elevated plus maze test time in the open arm among the several experimental groups**

The mean ± SEM open arm duration for the control, CdCl2 (14 days), CdCl2 (28 days), CdCl2 + Zinc, and CdCl2 + Vitamin E were 185.73 ± 10.66, 61.71 ± 18.21, 39.46 ± 18.66, 155.71 ± 7.96, and 193.66 ± 26.04, respectively.

Results showed that the CdCl2 group's open arm duration was considerably shorter (p < 0.05) than that of the control group. However, compared to the CdCl2 group, the open arm time was considerably longer (p < 0.05) in the CdCl2 + Zinc and CdCl2 + Vitamin E groups (see **Table 3**)*.*
