Time-course of changes in the social interaction test of anxiety following acute and chronic administration of nicotine

Irvine, E. E., Cheeta, S., File, S. E.·1999·Behavioural Pharmacology

Abstract

The purpose of these experiments was to explore the hypothesis that the effects of nicotine on anxiety depend on the time since administration and the duration of treatment. In the social interaction test of anxiety, acute nicotine administration (0.1 mg/kg, subcutaneously) decreased social interaction when rats were tested 5 min after injection, but increased it when they were tested 30 min after injection. Social interaction was also decreased 1 h post-injection, but levels returned to baseline between 3 and 30 h. As these changes were independent of any changes in locomotor activity, nicotine seemed to be having both anxiogenic and anxiolytic effects at different times after injection. An anxiolytic effect was also observed 30 min after the second nicotine injection, and the anxiogenic effect observed 5 min after injection remained after 4 days of nicotine administration. However, after 7 days of nicotine treatment, tolerance was observed to both these effects. When rats were tested 72 h after the last of 7 or 14 days of nicotine treatment, an anxiogenic withdrawal response was observed. Thus, an oppositional mechanism may underlie tolerance to the anxiolytic effects, whereas there is as yet no evidence for this type of mechanism mediating tolerance to the anxiogenic effects.

  • Nicotine injections 5 minutes before a social interaction test decreased social interaction, an anxiogenic effect, while injections 30 minutes before increased social interaction, an anxiolytic effect.

    “Irvine et al. (1999) found that nicotine injections 5 min before the behavioral test decreased social interaction, an anxiogenic effect, while injections 30 min before the task increased social interaction, an anxiolytic effect.”

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
