    Objective: p-Coumaric acid is commonly found in edible plants in nature and is known to be an effective antioxidant. This study aimed to investigate the therapeutic effects of p-coumaric acid on ethanol-induced gastric ulcer model Materials and Methods: After an 18-hour starvation period, the ulcer was induced in male Sprague-Dawley (250-300) rats by intragastric administration of 75\% ethanol. An hour after ulcer induction, p-coumaric acid (250 mg/kg) suspended in 1 ml tween-80 was administered intragastrically. The control and ulcer groups received 1 ml tween-80, One hour later, all rats were euthanized and stomach samples were collected for macroscopic examination, histological evaluation, and measurement of myeloperoxidase (MPO) activity, malondialdehyde (MDA), and glutathione (GSH) levels. Results: Ethanol induction resulted in gastric epithelial and mucosa' injury, increased MPO activity and MDA levels
