Gastroprotective Effects of Fraxin with Antioxidant Activity on the EthanolInduced Gastric Ulce

Objective: Here, we planned to evaluate whether fraxin performed a gastroprotective activity or not with its antioxidant properties on the ethanol-induced gastric ulcer. Methods: Wistar Albino male rats were assigned to 4 groups with 6 animals in each group. The groups were arranged as control (group I), ethanol (group II), ethanol+omeprazole (group III), and ethanol+fraxin (group IV) groups. All subjects were sacrificed 3 hours after administration of 70%, 10 mg/kg of ethanol. In groups III and IV, rats were given omeprazole 30 mg/kg and fraxin 50 mg/kg, respectively, by oral gavage 30 minutes before the ethanol induction. At the end of the experiment, the gastric tissues were removed, washed and the ulcer areas were macroscopically evaluated. Later, the samples were stored under appropriate conditions for biochemical analysis. Results: Superoxide dismutase (SOD) and glutathione (GSH) levels decreased, and malondialdehyde (MDA) value increased in group II compared to group I (p<0.05). However, these results changed significantly in groups III and IV (p<0.05). In group III, a significant reduction was noticed in gastric ulcer areas compared to group II (p<0.05). In group IV, the size of the gastric ulcer areas decreased considerably compared to group II (p<0.05). Conclusion: In the light of biochemical and macroscopic findings, fraxin showed a gastroprotective effect with its antioxidant activity against ethanol-induced gastric ulcers.
