Representative histological images of the colon contains fecal pellet, taken from vehicle, SP or FBe-treated normal rats. a = Intact vehicle control (Saline and distilled water administered intact vehicle control rats). b = LP control (LP 3 mg/kg and distilled water administrated constipation control rats). c = Reference (LP 3 mg/kg and SP 5 mg/kg administered rats). d = FBe 300 (LP 3 mg/kg and FBe the highest dosage 300 mg/kg administered rats). e = FBe 200 (LP 3 mg/kg and FBe the middle dosage 200 mg/kg administered rats). f = FBe 100 (LP 3 mg/kg and FBe the lowest dosage 100 mg/kg administered rats). FBe: Triple fermented barley extracts, test material; MM: Colonic mucosa; LU: Lumen; SM: Submucosa: ML: Muscular layer. Arrow indicated surface mucous thicknesses of fecal pellets measured.
