Gastroprotective effect of carob (Ceratonia siliqua L.) against ethanol-induced oxidative stress in rat

Abstract : BACKGROUND: We aimed in the present study, at investigating the gastroprotective effect of carob pods aqueous extract (CPAE) against ethanol-induced oxidative stress in rats as well as the mechanism implicated. METHODS: Adult male wistar rats were used and divided into six groups of ten each: control, EtOH (80% v/v, 4 g/kg b.w.), EtOH 80% + various doses of CPAE (500, 1000 and 2000 mg/kg, b.w.) and EtOH + Famotidine (10 mg/kg, p.o.) Animals were perorally (p.o.) pre-treated with CPAE during 15 days and intoxicated with a single oral administration of EtOH (4 g/kg b.w.) for two hours. RESULTS: The colorimetric analysis demonstrated that the CPAE exhibited an importance in vitro antioxidant activity against ABTS and DPPH radicals. We found that CPAE pretreatment in vivo, protected against EtOH-induced macroscopic and histological changes induced in stomach mucosa. Carob extract administration also protected against alcohol-induced volume gastric juice decrease. More importantly, We showed that CPAE counteracted EtOH-induced gastric lipoperoxidation, reversed the decrease of sulfhydryl groups (-SH) an hydrogen peroxide (H2O2) levels, and prevented the depletion of antioxidant enzyme activity of superoxide dismutase (SOD), catalase (CAT) and glutathione peroxidase (GPx). CONCLUSIONS: These findings suggest that CPAE exerted a potential gastro-protective effect against EtOH-induced oxidative stress in rats, due in part, to its antioxidants properties.
