**5.13 Comparison of the duration in the closed arm entry during (CAE Dur.) elevated plus maze test among the different experimental groups**

The mean ± SEM closed arm duration for the control, CdCl2 (14 days), CdCl2 (28 days), CdCl2 + Zinc, and CdCl2 + Vitamin E were 112.27 ± 10.92, 238.29 ± 18.21, 310.25 ± 12.81, 144.29 ± 7.96, and 106.34 ± 26.04, respectively.

The results showed that the CdCl2 group's duration in the closed arm was substantially longer (p < 0.05) than that of the control group. When compared to the CdCl2 group, the duration in the closed arm was considerably shorter for the CdCl2 + Zinc and CdCl2 + Vitamin E groups (p < 0.05) (see **Table 3**)*.*

### **5.14 Comparison of the frequency of open arm entry (Freq. OAE) during elevated plus maze test among the different experimental groups**

The mean ± SEM frequency of open arm entry for the control, CdCl2 (14 days), CdCl2 (28 days), CdCl2 + Zinc, and CdCl2 + Vitamin E groups were 9.40 ± 0.75, 2.80 ± 0.37, 1.48 ± 0.51, 8.20 ± 0.86, and 8.60 ± 0.51, respectively.

In comparison with the control group, the CdCl2 group's open arm entry frequency was significantly lower, according to the data (p < 0.05). The open arm entry frequency was significantly higher (p < 0.05) in the CdCl2 + Zinc and CdCl2 + Vitamin E groups as compared to the CdCl2 group (see **Table 3**).
