Protective effect of Nigella sativa oil against binge ethanol-induced oxidative stress and liver injury in rats

Chin J Nat Med. 2014 Jul;12(7):495-9. doi: 10.1016/S1875-5364(14)60077-7.

Abstract

Aim: Nigella sativa L. (Ranunculaceae) is considered as a therapeutic plant-based medicine for liver damage. In this study, the aim was to study the effect of Nigella sativa oil (NSO) pretreatment on ethanol-induced hepatotoxicity in rats.

Method: Rats were given Nigella sativa oil at doses of 2.5 and 5.0 mL·kg(-1), orally for 3 weeks, followed by oral ethanol (EtOH) administration (5 g·kg(-1)) every 12 h three times (binge model).

Results: Binge ethanol application caused significant increases in plasma transaminase activities and hepatic triglyceride and malondialdehyde (MDA) levels. It decreased hepatic glutathione (GSH) levels, but did not change vitamins E and vitamin C levels and antioxidant enzyme activities. NSO (5.0 mL·kg(-1)) pretreatment significantly decreased plasma transaminase activities, hepatic MDA, and triglyceride levels together with amelioration in hepatic histopathological findings.

Conclusion: NSO pretreatment may be effective in protecting oxidative stress-induced hepatotoxicity after ethanol administration.

Keywords: Binge ethanol; Liver; Nigella sativa; Oxidative stress; Rats.
