THE BENZODIAZEPINE RECEPTOR AND RECEPTOR TOLERANCE PRODUCED BY CHRONIC TREATMENT OF DIAZEPAM

INFLUENCE OF CCK RECEPTOR AGONIST AND ANTAGONISTS ON TOLERANCE INDUCED TO ANTIPENTYLENETETRAZOL ACTIVITY OF DIAZEPAM

In the present study, the effects of caerulein and CCK receptor antagonist< on tolerance to the anti-pentylenetetrazol activity of diazepam has been studied. Different doses of diazepam (20, 30, 35, 40 and 50 mg/kg) were administered intraperitoneally for a period of 6 days in order to induce tolerance to diazepam. 48 h after the last dose of diazepam, a test dose of diazepam was tested for...

GABAA Receptor α Subunits Differentially Contribute to Diazepam Tolerance after Chronic Treatment

BACKGROUND Within the GABA(A)-receptor field, two important questions are what molecular mechanisms underlie benzodiazepine tolerance, and whether tolerance can be ascribed to certain GABA(A)-receptor subtypes. METHODS We investigated tolerance to acute anxiolytic, hypothermic and sedative effects of diazepam in mice exposed for 28-days to non-selective/selective GABA(A)-receptor positive all...

Chronic cocaine modifies brain benzodiazepine receptor densities.

Effects of diazepam on 125I-iomazenil-benzodiazepine receptor binding and epileptic seizures in the El mouse.

OBJECTIVE To investigate changes in free benzodiazepine receptor density in response to repeated, long-term administration of diazepam in epilepsy, we assessed 125I-iomazenil (125I-IMZ) binding in a mouse model. METHODS El mice were divided into two groups of 12 mice each which received either no diazepam (E1(D[-]) group) or 2 mg/kg of diazepam per week (El(D[+]) group). Nine ddY mice were us...
