Zusammenfassung: | The purpose of the present study was to look at the effect of aspartame on the anxiolytic actions of ethanol. Previous research has shown that ethanol reliably produces an anxiolytic effect on rodent's plus-maze performance. There have been anecdotal reports that aspartame increases anxiety. CD-1 male mice were given i.p. aspartame doses of vehicle, 1000, or 2000 mg/kg, followed 30 min later by i.p. ethanol doses of 1.6 g/kg or vehicle. Animals were then placed in an open field, then tested in the plus-maze. Results determined that the aspartame condition had no significant effect on anxiety-related behavior, nor did it alter the anxiolytic actions of ethanol. Thus, acute high dose exposure to aspartame does not appear to affect anxiety-related behaviors. |
