Tolerance to nicotine's effects in the elevated plus-maze and increased anxiety during withdrawal

Irvine, Elaine E, Cheeta, Survjit, File, Sandra E·2001·Pharmacology Biochemistry and Behavior

Abstract

In the elevated plus-maze test of anxiety, nicotine (0.1 mg/kg sc; 30 min after injection) had a significant anxiogenic effect, shown by specific decreases in the percentage of time spent on the open arms and in the percentage of open-arm entries. Tolerance developed to this anxiogenic effect after 7 days of nicotine treatment (0.1 mg/kg/day). Five minutes after an acute injection, nicotine (0.1 mg/kg) was ineffective, but after 7 days of treatment a significant anxiolytic effect, shown by specific increases in the percentage of time spent on the open arms and in the percentage of open-arm entries, emerged. After 14 days of nicotine treatment, tolerance developed to this anxiolytic effect. There was a complete dissociation between the effects of nicotine on the measures of anxiety, and on the locomotor activity as measured by closed-arm entries. No changes in closed-arm entries were found after acute administration of nicotine, but rats tested 30 min after their 7th injection made significantly fewer, and those tested 5 min after their 14th injection made significantly more, entries than their respective controls. Rats that were tested after 24 h withdrawal from six daily nicotine injections showed a significant anxiogenic effect. A low dose of nicotine (5 ng) injected into the dorsal hippocampus was without effect in vehicle pretreated rats, but it was able to reverse the anxiogenic effect found after 24 h of withdrawal from 6 days of nicotine treatment.

  • Subcutaneous acute nicotine at 0.1 mg/kg increased anxiety-like behavior in the elevated plus maze 30 minutes after injection.

    “Irvine et al. (2001) found that subcutaneous injections of acute nicotine (0.1 mg/kg) increased anxiety-like behavior in the EPM 30 min after injection.”

  • Nicotine injections 5 minutes before the elevated plus maze test had an anxiolytic effect after 7 days of repeated administration.

    “Irvine et al. (2001) also found that injections 5 min before the EPM test had an anxiolytic effect after 7 days of repeated administration.”

  • Rats tested 24 hours after the last nicotine injection showed increased anxiety during withdrawal, and this effect was reversed by dorsal hippocampal infusions of nicotine.

    “rats tested 24 h after the last nicotine injection showed increased anxiety during withdrawal and this effect was reversed by dorsal hippocampal infusions of nicotine (Irvine et al., 2001).”

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.
