**5.7 Comparison of the elevated plus maze (REPM) test's frequency of rearing among the several experimental groups**

The mean ± SEM rearing frequency for the control, CdCl2 (14 days), CdCl2 (28 days), CdCl2 + Zinc, and CdCl2 + Vitamin E groups were 40.60 ± 3.89, 23.20 ± 3.73, 19.42 ± 3.86, 35.00 ± 3.54, and 40.40 ± 1.86, respectively.


### **Table 2.**

*Comparing the frequency of grooming during the Light/Dark Transition Box Test, the occurrence of regaining consciousness during the Elevated Plus Maze, the occurrence of the Stretch Attend Posture, the occurrence of Head Dips, and the occurrence of grooming during the Elevated Plus Maze among the various experimental groups.*

The results revealed that as compared to the control group, the rearing frequency in the CdCl2 group was considerably lower (p < 0.05). However, when compared to the CdCl2 group, the rearing frequency in the CdCl2 + Vitamin E group was considerably greater (p < 0.05) (see **Table 2**)*.*
