Abstract

Anxiety is a key symptom of the cocaine withdrawal syndrome in human addicts, and it is considered to be one of the major factors in precipitating relapse to chronic cocaine abuse. Corticotropin-releasing factor (CRF) plays an important role in the pathophysiology of anxiety and depression, and it may also be involved in the acute behavioral and neuroendocrine actions of cocaine. The role of endogenous CRF in cocaine withdrawal-induced anxiety was investigated in the present study. Animals were subjected to chronic cocaine (20 mg/kg, intraperitoneally, once a day for 14 days) administration. Rats tested 30 min after the last cocaine injection did not show withdrawal anxiety on the elevated plus maze or any alterations in brain CRF levels. Withdrawal (48 h) from chronic cocaine administration produced an intense anxiety-like behavior characterized by decreased open arm exploration. Immunoreactive CRF (CRF-LI) levels were selectively altered in the hypothalamus, in the amygdala and in the basal forebrain structures at the time of the behavioral anxiety, reflecting an increased activity of brain CRF systems. Daily intracerebroventricular (i.c.v.) pretreatment with an immunoserum raised against CRF completely prevented the development of anxiety induced by cocaine withdrawal. These data suggest that extrahypothalamic-limbic CRF hypersecretion may be involved in the development of anxiety related to cocaine withdrawal and that the CRF system may be a useful target for new pharmacotherapies for cocaine withdrawal and relapse.

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.
