Abstract
The oral intake of alcohol has become a widespread concern due to its high risk to body health. Therefore, our purpose in this study was to reveal the antioxidant efficacies of natural Commiphora myrrha on hepatotoxicity and oxidative stress induced by ethanol in adult male rats, especially because these were not adequately revealed by previous studies. We examined the impacts of C. myrrha in male Sprague Dawley rats orally treated with C. myrrha (500 mg/kg) alone or in combination with 40% ethanol (3 g/kg), daily for 30 days. The results showed that treatment with C. myrrha after the oral consumption of ethanol caused a reduction in serum liver function parameters (alanine transferases, aspartate transaminase, and total bilirubin), hepatic tumor markers (alpha-L-flucosidase and arginase), and hepatic lipid peroxidation indicator (thiobarbituric acid reactive substances), as well as a slight restoration (not significant) in the levels of superoxide dismutase, catalase, reduced glutathione; and total antioxidant capacity. In addition, it alleviated histopathological changes in the liver, as revealed by decreased areas of inflammatory infiltrate, milder necrosis, and noticeably reduced periportal fibrosis and hemorrhage. The therapeutic efficiency of C. myrrha could be due to its rich sesquiterpenoids content which possesses anti-inflammatory properties and ROS-scavenging activities. Our findings provide evidence that the attenuation of oxidative stress by C. myrrha enables hepatic tissue to suppress inflammatory and oxidative mechanisms, resulting in enhanced liver structure and function. Therefore, C. myrrha extract shows promise as a protective and therapeutic supplement against toxic agents.
