    Notes: Summary Pretreatment with pertussis toxin (0.5 and 1.0 μg/animal, i. c. v., seven days prior to testing) reversed the reduction in locomotor activity in the holeboard test caused by administration of the alpha2-adrenoceptor agonist, medetomidine (0.1 mg/kg, i. p.). Intrinsic behavioral effects of pertussis toxin treatment were also observed, these included a reduction in exploratory head-dipping and an increase in locomotor activity. These doses of pertussis toxin also reduced the ataxia induced by a 2.4 g/kg dose of ethanol. Pertussis toxin treated animals also exhibited a diminished hypothermic response to ethanol (2 g/kg), although the pertussis toxin treated animals had lower body temperatures prior to ethanol administration compared to sham treated animals. Neither the behavioral effect of pertussis holotoxin in the holeboard nor its effects on reversing medetomidine hypolocomotion or ethanol-induced ataxia were seen following administration of the binding oligomer of pertussis toxin which binds to the cell membrane but does not possess the enzymatically active subunit. These findings implicate mechanisms involving pertussis toxin sensitive G-proteins in modulating some behavioral and physiological effects of ethanol.

    Notes: Abstract The social behavior of pairs of male NIH Swiss mice was assessed under a variety of experimental conditions. Increasing periods of isolation increased both the total time spent in social interaction and also increased the incidence of aggressive behavior. Familiarity with the testing arena tended to increase social behavior, but the magnitude of this effect was considerably less than that previously observed in rats. High light levels reduced social interaction. Ethanol (0.8–2.4 g/kg) caused a dose-related decrease in the total time spent in social interaction, a biphasic effect on aggressive behavior and a dose-related increase in locomotor activity. While the social interaction test in this form may not be a suitable model of anxiety in NIH Swiss mice, it should provide a useful method of assessing drug effects and investigating genetic influences on social and aggressive behavior.

    Notes: Abstract The activity of rats in a holeboard test is reduced 30, 90, and 240 min after treatment with a single dose of lorazepam. The administration of a benzodiazepine antagonist (RO 15-1788) 20 min before the holeboard test (i.e., 10, 70, or 220 min after lorazepam administration) reverses the hypoactivity of animals tested 30 min after treatment with lorazepam, partially reverses the hypoactivity of animals tested 90 min after receiving lorazepam, but is without effect on the hypoactivity observed 240 min after treatment with the benzodiazepine. If, however, RO 15-1788 is given at the same time as lorazepam then it reverses the hypoactivity seen 4 h later. The results of these experiments demonstrate that a benzodiazepine can exert a behavioral effect at a time when it no longer appears to be acting at central benzodiazepine receptors.

    Behavioral effects of alpha2 adrenoceptor antagonists and their interactions with ethanol in tests of locomotion, exploration and anxiety in mice (1989)

    Notes: Abstract The behavioral effects of two highly selective alpha2-adrenoceptor antagonists, atipamezole and idazoxan, were investigated in mice using the plusmaze test of anxiety and the holeboard test of directed exploration and locomotor activity. No anxiogenic effect, as assessed by the tendency to enter the closed as opposed to open arms of the plusmaze, was noted for either drug at any dose tested. Neither were there any significant effects on locomotor activity or directed exploration (head-dipping) in the holeboard, or total plusmaze arm entries at any dose of either drug. The co-administration of either atipamezole or idazoxan had no effect on either the anxiolytic effect of ethanol (2 g/kg) or its locomotor stimulant effect in the holeboard. Atipamezole (1.0 and 3.0 mg/kg) significantly reversed the ethanol-induced reduction in exploratory head-dipping; a similar trend was seen for idazoxan. There was also a significant potentiation of the ethanol-induced increase in the number of total arm entries made on the plusmaze caused by 1.0 mg/kg (but not 3.0 mg/kg) atipamezole and both 0.3 and 1.0 mg/kg idazoxan. The results suggest that some of the behavioral effects of ethanol can be reversed by alpha2-adrenoceptor antagonists whilst others are unchanged.

    Behavioral interactions of fluoxetine and other 5-hydroxytryptamine uptake inhibitors with ethanol in tests of anxiety, locomotion and exploration (1988)

    Notes: Abstract The 5HT uptake inhibitor fluoxetine had no effect on motor activity or directed exploration (head-dipping) in a holeboard test or in an elevated plusmaze test of anxiety. Fluoxetine (20 mg/kg) attenuated the anxiolytic effect of a 2.4 g/kg dose of ethanol in the plusmaze but failed to alter ethanol's effects on exploratory head-dipping or locomotion. This interaction did not seem directly related to fluoxetine's 5HT uptake inhibiting properties because it was not observed with other 5HT uptake inhibitors (fluvoxamine and citalopram). Desipramine, which predominantly inhibits noradrenaline uptake, also failed to show effects similar to those of fluoxetine.

    Time course of ethanol's effects on locomotor activity, exploration and anxiety in mice (1988)

    Notes: Abstract The time course of the effects of two doses of ethanol on exploration, locomotor activity and anxiety were investigated using the holeboard and plus-maze tests. In an 8 min holeboard test the lower (1.2 g/kg) dose increased both exploration and locomotor activity 0.5 h after ethanol administration whereas the higher (2.4 g/kg) dose decreased exploration but caused an even greater increase in locomotor activity. This activity increase was also seen 1 h postadministration. In the plus-maze test both doses showed an increased number of arm-entries 0.5 h and 1 h after administration but only the 2.4 g/kg dose caused anxiolytic effects persisting for over 2 h. The results add further support to the notion that the behavioral effects of ethanol vary with dose, time of administration and the behavioral measure taken.

    Behavioral effects of the inhibitors of phenylethanolamine-N-methyltransferase, LY 78335 and LY 134046, and their interactions with ethanol (1990)

    Notes: Abstract The centrally active inhibitors of phenylethanolamine-N-methyltransferase (PNMT), LY 78335 and LY 134046, were investigated both alone and in combination with ethanol (2 g/kg) in a holeboard test of directed exploration and locomotor activity. Both PNMT inhibitors showed dose-related reductions in exploratory head-dipping but were without effect on locomotor activity. In combination with ethanol both PNMT inhibitors tended to attenuate the ethanol-induced reductions in exploratory head-dipping but did not effect ethanol's locomotor stimulant properties. LY 134046 showed neither an anxiolytic nor an anxiogenic profile in the plusmaze test of anxiety, nor did it alter the anxiolytic effects of either 1.2 g/kg or 2 g/kg ethanol. LY 134046 did, however, attenuate the ataxic effects of a 2.4 g/kg dose of ethanol. These results may suggest a role for adrenaline synthesis in some, but not all, of the behavioral effects of ethanol.
