| Abstract | The present study examined the antiucler effect of glucosamine on mucosal antioxidant defense system in ibuprofen-induced peptic ulcer in male albino rats.The number of lesions in the gastric mucosa, volume of gastric juice, acid output, peasin activity, lipid peroxides, reduced glutathione conttent and the activities of glutathione dependent antioxidant enzymes (glutathione peroxidase and glutathione-S-transferase)and antiperoxidative enzymes (catalase and superoxide dismutase)were determined. Prior oral administration of glucosamine significantly prevented the ibuprofen-induced increases in the number of lesions in the gastric mucosa, volume of gastric juice and acidity .It also maintained the activity of pepsin at near normal level.Oral pretreatment of glucosamine exerted a significant antioxidant effect by preventing ibuprofen-induced lipid peroxidation and by maintaining the levelof reduced glutathione and the activities of muscosal antioxidant enzymes at near normalcy.The results of the present investigation indicate that the antiulcer activity of glucosamine is related to its ability to neutralize the hydrochloric acid secreted into the stomach and to its antioxidant capability to inhit ibuprofen-induced lipid peroxidation. |
