Abstract

The present study investigated the effects of subchronic nicotine, mecamylamine and hexamethonium, alone or in combinations, on locomotor activity and behavioral inhibition. Rats were divided into groups and tested for locomotor activity after acute nicotine. The different groups received vehicle, nicotine, mecamylamine, mecamylamine+nicotine, hexamethonium (two different concentrations) and hexamethonium+nicotine injections once a day for 15 days after which they were tested for nicotine-induced locomotor activity again. Acutely, nicotine stimulated locomotor activity, and repeated daily nicotine or hexamethonium+nicotine administration sensitized the animals to this nicotine-induced locomotor stimulation (locomotor sensitization). Mecamylamine administered subchronically in combination with nicotine was able to block the induction to locomotor sensitization to nicotine. None of the nicotinic receptor antagonists induced locomotor sensitization to nicotine by themselves. In the elevated plus-maze, subchronic nicotine treatment demonstrated a nicotine-induced behavioral disinhibition, measured as an increase of time spent in and entries made into open arms. In contrast to the findings regarding locomotor sensitization, none of the antagonists counteracted the induction of this nicotine-induced behavioral disinhibition after subchronic co-treatment with nicotine. In addition, both antagonists by themselves produced a similar effect as subchronic nicotine, i.e. promoted the development of nicotine-induced disinhibitory behavior. It was concluded that the induction of locomotor sensitization to nicotine involves stimulation of central nicotinic acetylcholine receptors, whereas the development of nicotine-induced behavioral disinhibition involves blockade of peripheral nicotinic acetylcholine receptors, and that the latter, but not the former, phenomenon from a pharmacological point of view appears to be related to the increased ethanol consummatory behavior observed after subchronic nicotine administration.

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.
