Representative gross stomach images taken from intact or IND-treated mice. a: Intact control (DW 5 ml kg^− 1, twice administered rats with 30 min-intervals). b: IND control (DW 5 ml kg^− 1 and IND 25 mg kg^− 1 administered gastric mucosal damage induced vehicle control rats). c: OM (OM 10 mg kg^− 1 and IND 25 mg kg^− 1 administered reference drug treated rats). d: FBe 300 (FBe 300 mg kg^− 1 and IND 25 mg kg^− 1 administered the highest dosage experimental rats). e: FBe 200 (FBe 200 mg kg^− 1 and IND 25 mg kg^− 1 administered the middle dosage experimental rats). f: FBe 100 (FBe 100 mg kg^− 1 and IND 25 mg kg^− 1 administered the lowest dosage experimental rats). FBe: triple fermented barley extract as test material; DW: Distilled water; IND: indomethacin; OM: omeprazole; CA: cardiac regions of stomach; FU: fundus regions of stomach; PY: pylorus regions of stomach. All test substances were single orally administered, at 30 min before IND 25 mg kg^− 1 single oral treatment, and all animals were sacrificed at 6 h after IND treatment. Scale bars = 11 mm
