**5.10 Comparison of the various experimental groups' grooming frequency throughout the elevated plus maze test**

The mean ± SEM grooming frequency for the control, CdCl2 (14 days), CdCl2 (28 days), CdCl2 + Zn, and CdCl2 + Vitamin E groups were 2.60 ± 0.40, 7.20 ± 0.58, 10.40 ± 0.28, 2.20 ± 0.58, and 1.80 ± 0.37, respectively.

Results showed that the CdCl2 group's grooming frequency was substantially higher (p < 0.05) than that of the control group. When compared to the CdCl2 group, grooming frequency was considerably reduced (p < 0.05) in the CdCl2 + Zinc and CdCl2 + Vitamin E groups (see **Table 2**)*.*
