Abstract:
Introduction: Arsenic (As) is a toxic metal, which causes disorders in various tissues of the body, including the liver. Studies have shown that exercise and herbs such as Tribulus terrestris (T) have antioxidant effects on some diseases. The present study aimed to investigate the effects of endurance training (ET) and T extract on oxidative stress and apoptosis markers in the liver tissues of rats exposed to As. Methods: This experimental study was conducted on ۴۹ rats, which were randomly assigned into seven groups of control, As, As with ۵ mg/kg of T extract (As+T۵), As with ۱۰ mg/kg of T extract (As+T۱۰), As with ET, As with ET and ۵ mg/kg of T extract (As+ET+T۵), and As with ET and ۱۰ mg/kg of T extract (As+ET+T۱۰). For eight weeks, study groups ۲-۶ consumed sodium arsenite (۶۸ mg/l per day) dissolved in drinking water, and groups ۵-۷ ran on a treadmill five sessions per week (۳۰ minutes per session) at the speed of ۲۳ meters per minute. Results: Exposure to As significantly increased O-۶-methylguanine-DNA methyltransferase (MGMT), cytochrome C, malondialdehyde (MDA), and prooxidant-antioxidant balance (PAB), while decreasing hepatic adenosine triphosphate (ATP) (P=۰.۰۰۱). Training and T extract consumption reduced the concentration of MGMT, cytochrome C, MDA, and PAB, while increasing the hepatic ATP concentration (P=۰.۰۰۱). The T extract at the dose of ۱۰ mg/kg could increase the ATP concentration and decrease cytochrome C, MDA, and PAB more significantly in the liver tissues compared to the dose of ۵ mg/kg (P=۰.۰۰۱). In addition, the interactive effects of training and T extract consumption were significant on the reduction of MGMT, cytochrome C, MDA, and PAB concentrations and increasing the hepatic ATP concentration in the rats poisoned with As (P=۰.۰۰۱). Conclusion: According to the results, endurance training with the consumption of Tribulus terrestris extract could inhibit oxidative stress and apoptosis, thereby exerting protective effects on liver tissues against arsenic poisoning. Therefore, these interventions could effectively diminish the effects of arsenic induction on liver tissues.
