Abstract

|
Objectives : The object of this study was to observe the protective effects of 8 types of individual herbal components of Yijintang-gamibang, on the reflux esophagitis (RE) in rats as compared with omeprazole.
Methods : Each 100 mg/kg individual herbal component was orally pretreated, at 1 hr before and 6 hrs after pylorus and forestomach ligation, the changes on the esophageal lesion areas, gastric volumes, acid and pepsin outputs, antioxidant effects, esophageal total hexose and sialic acid contents were observed with changes on the esophageal histopathology. The results were compared with an omeprazole 10 mg/kg treated group.
Results : Pylorus and forestomach ligation-induced RE were inhibited by treatment of all 8 herbal components and omeprazole except for Pinella Rhizoma and Massa Meicata Fermentata, in order of Atractylodis Rhizoma, Citri Pericarpium, omeprazole, Glycyrrhizae Radix, Hordei Fructus Germiniatus, Holelen and Citri Pericarpium, as compared with RE control. Pinella Rhizoma and Massa Meicata Fermentata did not show any favorable protective effects against RE nor antioxidant effects in the present study.
Conclusions : The main active herbal components showing favorable protective effects on RE of Yijintang-gamibang mediated by antioxidant effects, were Atractylodis Rhizoma, Citri Pericarpium, Glycyrrhizae Radix, Hordei Fructus Germiniatus, Holelen and Citri Pericarpium. Furthermore Atractylodis Rhizoma and Citri Pericarpium showed more favorable protective effects as compared with omeprazole, therefore, it is expected that Atractylodis Rhizoma and Citri Pericarpium have potential as new alternatives or safe therapeutics against RE.
