| 520 | _aOxidative stress, arising from disrupted balance between reactive oxygen/nitrogen species (ROS/RNS) and antioxidant defences, has been implicated in the pathogenesis of stress-related disorders. There is a growing body of evidence that supports the relationship between the activity of the hypothalamic-pituitary-adrenal (HPA) stress system, oxidative stress and magnesium (Mg) homeostasis. The present study aimed to explore the gap in our current understanding of antigenotoxic and protective effects of Mg supplementation against excessive ROS production in male rats during chronic treatment with adrenocorticotropic hormone (ACTH). Our findings show that exposure to exogenous ACTH (10 μg/day, s.c., for 21 days), as one of the key mediators of the HPA axis and stress response, produced an increase in superoxide anion levels and a decrease in superoxide dismutase activity in plasma. We observed that Mg supplementation, starting seven days prior to ACTH treatment and lasting 28 days (300 mg/L of drinking water, per os), abolished these effects in experimental animals. Moreover, our study reveals that ACTH increased the susceptibility of peripheral blood lymphocytes to ex vivo H2O2-induced total and high-level oxidative DNA damage, while Mg completely reversed these effects. Collectively, these results highlight the promising role of Mg in stress-related conditions accompanied by increased oxidative stress in animals and support further investigation using human dietary trials. | ||
