In rats treated with naproxen, the administration of AST (1, 5, or 25 mg/kg BW; twice daily for three days) showed protective effects against naproxen-induced gastric ulcer by reversing decreased the activities of SOD, CAT, and GPX, and increased the lipid peroxide level to that of untreated normal rats [105]. This evidence concerns the gene CAT and gastric ulcer.
