METHODS
In total, 60 healthy male 6-week old Sprague-Dawley SD (SPF/VAF Outbred CrljOri:CD1) rats were commercially purchased. The FBe extract (100, 200, and 300 mg kg- 1) was orally administered 30 min before an oral treatment of IND (25 mg kg- 1). Six hours after IND treatment, variations in the histopathology, myeloperoxidase (MPO) activity, gross lesion scores, lipid peroxidation, and antioxidant defense system component (superoxide dismutase (SOD), catalase (CAT), and glutathione (GSH)) levels were measured.RESULTS
FBe treatment showed significant (p < 0.01 or p < 0.05) and dose-dependent decrease in gastric mucosal damage. In the present study hemorrhagic gross lesions, gastric MPO activity, and histopathological gastric ulcerative lesions were observed in IND-treated rats compared to the IND control rats. In particular, FBe, in a dose-dependent manner, strengthened the antioxidant defense systems, decreased lipid peroxidation and CAT activity by increasing the GSH levels and SOD activity, respectively. The 200 mg kg- 1 dose of FBe was similarly gastroprotective as the 10 mg kg- 1 dose of omeprazole in rats with IND-induced gastric mucosal damage.
