Taking into account that lipid oxidation products may exertanti-inflammatory properties [13, 14], the aims of this studywere to determine whether the treatment with OSO (4, 12, and24 mg/kg) might reduce acute gastric ulceration induced byabsolute ethanol and if it is so, to determine the potentialchanges in the activities of certain antioxidant enzymes such asSOD, catalase (CAT), and GSH-Px. Here, CAT is linked to gastric ulcer.
