Amelioration on oxidative stress, testosterone, and cortisol levels after administration of Vitamins C and E in albino rats with chronic variable stress

Background and Aim:Stress can cause physiological and biological disorders in the body. On the other hand, antioxidants from vitamins and minerals are effective for stress treatment. Therefore, this study aimed to evaluate the effect of the administration of Vitamins C and E on serum superoxide dismutase (SOD), malondialdehyde (MDA), catalase (CAT), glutathione peroxidase (GPx), testosterone, and cortisol activity in albino rats with chronic variable stress (CVS).

Materials and Methods:Twenty albino rats were randomly assigned into four treatment groups: C was administered
normal saline; T1 was administered Vitamins C and E; T2 was only induced CVS; and T3 was induced CVS followed by Vitamins C and E administration. All treatments were applied for 4 weeks, respectively. Furthermore, 5 mL of blood
samples were collected intracardially. Body weight data were collected for the initial and final weights. From serum
samples, SOD, GPx, and CAT were measured using the enzymol method; MDA was measured using the high-performance
liquid chromatography method; and testosterone and cortisol were measured using the enzyme-linked immunosorbent assay
method. All variables were analyzed statistically using analysis of variance followed by the Duncan test (p<0.05).
Results:Our findings showed that the T1 and T3 groups significantly decreased (p<0.001) compared to T2 in the
following parameters: SOD, MDA, GPx, and cortisol. Meanwhile, CAT and testosterone levels in the T1 and T3 groups were significantly increased (p<0.001) compared to the T2 group. In addition, the weight gain in T1 and T3 groups was significantly increased (p<0.001) compared to T2 group.

Conclusion:It can be concluded that the administration of Vitamins C and E had a significant effect to alleviate SOD,
MDA, GPx, and cortisol and to improve the testosterone level in albino rats with CVS.
