Abstract

The molecular defence mechanisms against ethanol- and stress- induced (WRS) gastric lesions under the action of plant 87ISSN 0201-8489 Фізіол. журн., 2006, Т. 52, № 6 proanthocyanidins from grapefruit-seed extract (GSE) were investigated. Pre-treatment with GSE (8-64 mg/kg/day) in dose- dependent manner attenuated gastric lesions induced by 100% ethanol and WRS; the doses of GCE reducing these lesions by 50% (ID50) were 28 and 36 mg/kg/day, respectively and this protective effect was similar to that obtained with PGE2 ana- logue. Lesions reduction was also accompanied by improve- ment of gastric blood flow, antiradical action, increased mu- cosal generation of PGE2, antioxidant activity.
