Nicotine Improves Working Memory Span Capacity in Rats Following Sub-Chronic Ketamine Exposure

All rights reserved 0893-133X/11 www.neuropsychopharmacology.org Nicotine Improves Working Memory Span Capacity in Rats Following Sub-Chronic Ketamine Exposure Samantha L Rushforth1, Thomas Steckler2 and Mohammed Shoaib*,1 1 2 Institute of Neuroscience, Newcastle University, Newcastle upon Tyne, Newcastle, UK; Janssen Research & Development, Beerse, Belgium Ketamine, an NMDA-receptor antagonist, produces cognitive deficits in humans in a battery of tasks involving attention and memory. Nicotine can enhance various indices of cognitive performance, including working memory span capacity measured using the odor span task (OST). This study examined the effects of a sub-chronic ketamine treatment to model cognitive deficits associated with schizophrenia, and to evaluate the effectiveness of nicotine, antipsychotic clozapine, and the novel mGlu2/3 agonist, LY404039, in restoring OST performance. Male hooded Lister rats were trained in the OST, a working memory task involving detection of a novel odor from an increasing number of presented odors until they exhibited asymptotic levels of stable performance. Sub-chronic ketamine exposure (10 and 30 mg/kg i.p. for 5 consecutive days) produced a dose-dependent impairment that was stable beyond 14 days following exposure. In one cohort, administration of graded doses of nicotine (0.025–0.1 mg/kg) acutely restored the performance in ketamine-treated animals, while significant improvements in odor span were observed in control subjects. In a second cohort of rats, acute tests with clozapine (1–10 mg/kg) and LY404039 (0.3–10 mg/kg) failed to reverse ketamine-induced deficits in doses that were observed to impair performance in the control groups. -

Problematic Use of Nitrous Oxide by Young Moroccan–Dutch Adults

Box 22660, 1100 DD Amsterdam, The Netherlands * Correspondence: [email protected] Abstract: The recreational use of nitrous oxide (N2O; laughing gas) has largely expanded in recent years. Although incidental use of nitrous oxide hardly causes any health damage, problematic or heavy use of nitrous oxide can lead to serious adverse effects. Amsterdam care centres noticed that Moroccan–Dutch young adults reported neurological symptoms, including severe paralysis, as a result of problematic nitrous oxide use. In this qualitative exploratory study, thirteen young adult Moroccan–Dutch excessive nitrous oxide users were interviewed. The determinants of problematic nitrous oxide use in this ethnic group are discussed, including their low treatment demand with respect to nitrous oxide abuse related medical–psychological problems. Motives for using nitrous oxide are to relieve boredom, to seek out relaxation with friends and to suppress psychosocial stress and negative thoughts. Other motives are depression, discrimination and conflict with friends Citation: Nabben, T.; Weijs, J.; van or parents.

Neurochemical Mechanisms Underlying Alcohol Withdrawal
Neurochemical Mechanisms Underlying Alcohol Withdrawal John Littleton, MD, Ph.D. More than 50 years ago, C.K. Himmelsbach first suggested that physiological mechanisms responsible for maintaining a stable state of equilibrium (i.e., homeostasis) in the patient’s body and brain are responsible for drug tolerance and the drug withdrawal syndrome. In the latter case, he suggested that the absence of the drug leaves these same homeostatic mechanisms exposed, leading to the withdrawal syndrome. This theory provides the framework for a majority of neurochemical investigations of the adaptations that occur in alcohol dependence and how these adaptations may precipitate withdrawal. This article examines the Himmelsbach theory and its application to alcohol withdrawal; reviews the animal models being used to study withdrawal; and looks at the postulated neuroadaptations in three systems—the gamma-aminobutyric acid (GABA) neurotransmitter system, the glutamate neurotransmitter system, and the calcium channel system that regulates various processes inside neurons. The role of these neuroadaptations in withdrawal and the clinical implications of this research also are considered.
