Abstract: The present study was to determine the protective effect of apple polyphenols on acute ethanol-induced neurobehavioral damages in mice as well as its possible mechanism of action. A loss of righting reflex test in mice was used to study the protective effect of apple polyphenols on the hypnotic effect caused by acute ethanol intake (4.0g/kg, i.p). Rotarod performance test in mice was used to study the protective effect of apple polyphenols on motor ataxia caused by acute ethanol intake (2.4g/kg, i.p). Blood ethanol concentration and alcohol dehydrogenase activity were measured using assay kits. Pretreatment with apple polyphenols (400 and 800mg/kg) for 1, 3, and 7 days significantly shortened acute ethanol-induced duration of righting reflex loss in Loss of Righting Reflex Test. Pretreatment with apple polyphenols (200mg/kg) for 3 and 7 days and apple polyphenols (200, 400 and 800mg/kg) for 1, 3, and 7 days significantly prolonged the latency to fall off the rotarod after acute ethanol injection in rotarod performance test. All doses of apple polyphenols decreased blood ethanol concentration while apple polyphenols (800mg/kg) increased hepatic alcohol dehydrogenase activity after acute ethanol injection. These results indicate that apple polyphenols have significant protective effects against the hypnotic effect and motor ataxia induced by acute ethanol. These effects may partially occur via a mechanism linked to promoting ethanol metabolism.
