Hepatoprotective Effects of Nigella sativa essential oil against Acrylamide-induced Oxidative Stress and Inflammatory Cytokine Changes in Wistar Albino Rats

Abstract

This study was designed to investigate the possible protective efficacy of Nigella sativa essential oil against acrylamide induced liver toxicity. Four groups of 32 male Wistar albino rats were formed. Control group was used as a control. acrylamide was administered to the rats in Group AA by gavage at a daily dose of 40 mg/kg. 10mg/kg dose of Nigella sativa essential oil was administered intraperitoneally to the rats in Group NS. In Group AA+NS, daily acrylamide and Nigella sativa essential oil applications were carried out simultaneously as mentioned above. The trial period lasted 15 days. While acrylamide increased malondialdehyde levels in liver tissue, it decreased glutathione and superoxide dismutase levels. In addition, liver pro-inflammatory cytokine levels increased due to acrylamide administration, while anti-inflammatory cytokine levels decreased due to acrylamide administration.: Concomitant administration of Nigella sativa essential oil with acrylamide significantly reduced oxidative stress and inflammation in liver tissues. In conclusion, our findings emphasized that Nigella sativa essential oil has a potential therapeutic role to prevent acrylamide-induced hepatotoxicity.
