title: Prevention of ethanol-induced gastric damage by the imidazobenzodiazepines Ro 15-4513 and Ro 15-3505 in rats.
abstract: The protective effects of the imidazobenzodiazepines Ro 15-4513 and Ro 15-3505 against ethanol-induced gastric damage were investigated. Gastric lesions were induced in rats by the oral administration of 1 ml of absolute ethanol. Ro 15-4513 (2.5-10 mg/kg, IP) or Ro 15-3505 (5-20 mg/kg, IP), administered 30 min before ethanol, protected against ethanol-induced gastric damage. The protective effects of these compounds were blocked by the benzodiazepine antagonist, flumazenil (10 mg/kg, IP). These results present evidence for the involvement of the GABA-benzodiazepine receptor complex in the pathogenesis of ethanol-induced gastric damage.
