The aim of this study was carried out to investigate the protective effect of Rhizoma Dioscoreae on the gastric mucosal lesions induced by alcohol in rats. Experimental groups were treated by oral infusion with Rhizoma Dioscoreae extract at the dose of 0.03465 g/ml(OA-RD1 group), 0.0693 g/ml(OA-RD2 group), and 0.1386 g/ml(OA-RD3 group), while D.W group was administrated with the distilled water and control group did not pretreated. Experimental groups pretreated for 14 days, and given orally 1 ml of 75% alcohol two times(30min interval). The animals were killed 1hr 30min after alcohol treatment, and measured rats body weight, absolute stomach weight, relative stomach weight, SOD activity, glutathione peroxidase(GPx) activity, observed gastric mucosal lesions. The body weight was unremarkable changed. In once as dose intake group’s absolute stomach weight was increased and In once as dose intake group, twice as dose intake group’s relative stomach weight was increased. SOD activity, glutathione peroxidase activity in twice as dose intake group is remarkably increased. Light microscopy Observations of congestion, hemorrhage, and erosion in gastric mucosal lesions were shown severely in control group than OA-RD1, OA-RD2, OA-RD3. These results suggest that the proposed gastroprotective effect may involve activation of antioxidant effect. And Twice as dose is especially effective.
