We evaluated the antiulcerogenic activity of the ethanol extract in hypothermic restraint stress-, indomethacin-, necrotizing agents- (80% ethanol, 25% NaCl and 0.2 M NaOH ) induced ulcers and basal gastric acid secretion using pylorus ligated Shay rat-model. Marjoram at doses of 250 and 500 mg\/kg of body weight, significantly decreased the incidence of ulcers, basal gastric secretion and acid output. Furthermore, the extract replenished the ethanol-induced depleted gastric wall mucus and nonprotein sulfhydryls (NP-SH) contents and significantly lowered the increase in the concentration of malondialdehyde (MDA). Ulcer preventing potential was further confirmed by histopathological assessment. An acute toxicity test showed a large margin of safety of the extract in mice. The phytochemical screening of aerial parts of marjoram revealed the presence of volatile oil, flavonoids, tannins, sterols and\/or triterpenes.<\/jats:p>","DOI":"10.1142\/s0192415x0900703x","type":"journal-article","created":{"date-parts":[[2009,7,15]],"date-time":"2009-07-15T03:12:28Z","timestamp":1247627548000},"page":"531-545","source":"Crossref","is-referenced-by-count":38,"title":["Protective Effect of<i>Origanum majorana<\/i>L.
