The object of this study was to observe the protective effects of Yijin-tang-gamibang (YJGMB), Yijin-tang has been traditionally used in the Korean Medicine for treating various digestive diseases. The study showed that it is effective on reflux esophagitis induced by pylorus and forestomach ligation in rats. Three different dosages of YJGMB extracts, 200, 100 and 50 mg/kg, were orally pretreated, once a day for 28 days before pylorus and forestomach ligation. Seven groups, each of 8 rats per group were used in the present study. The results were compared with omeprazole, antioxidant and proton pump inhibitor, 30 and 10 mg/kg treated group. YJGMB 200 mg/kg were showed similar protective effects as compared with 30 mg/kg of omeprazole but more favorable effects were observed in 200, 100 and 50 mg/kg of all YJGMB treated rats as compared with omeprazole 10 mg/kg in the present study. In addition, YJGMB 200 mg/kg were showed more favorable antioxidant effects as compared with 30 mg/kg of omeprazole in the present study. Detail mechanism studies should be conduced in future with the screening of the biological active chemical compounds in herbs.

The object of this study was to observe the protective effects of Yijin-tang-gamibang (YJGMB), Yijin-tang has been traditionally used as Korean medicine for treating various digestive diseases. The study showed that it is effective on reflux esophagitis induced by pylorus and forestomach ligation in rats. Three different dosages of Yijin-tang-gamibang extracts, 300, 150 and 75 mg/kg, were once orally administered 1 hour before pylorus ligation. 6 groups, each of 8 rats per group were used in the present study. The results were compared with Omeprazole, antioxidant and proton pump inhibitor, 30 mg/kg treated group. Yijin-tang-gamibang extracts 300 mg/kg were showed similar or slightly lower effects as compared with 30 mg/kg of omeprazole in the present study. Detail mechanism studies should be conduced in future with the efficacy tests of individual herbal composition of Yijin-tang-gamibang and the screening of the biological active compounds in herbs.
