We hereby report that repeated administration of ketamine (350 mg/kg in total) and methamphetamine (30 mg/kg in total) causes specific glutamatergic and dopaminergic neuron deficits, respectively, in adult mouse brain. Acute ketamine did not affect basal body temperature or the later methamphetamine-induced hyperthermia. However, pretreatment with repeated(More)
Currently, joint use of ketamine and 3,4-methylenedioxymethamphetamine (MDMA, Ecstasy) represents a specific combination of polydrug abuse. Long-lasting and even aggravated central neuronal toxicity associated with mixing ketamine and MDMA use is of special concern. This study was undertaken to examine the modulating effects of ketamine treatment on later(More)
Drug memory plays an important role in priming subsequent drug use. We used drug-induced conditioned place preference (CPP) as a paradigm to study such drug memory. In this paradigm, repeated association of specific environmental cues with abused drug-induced subjective euphoria has been suggested to motivate later biased approaching behavior toward the(More)
RATIONALE AND OBJECTIVE Whether monoamine oxidase inhibitors (MAOIs) can be used to suppress the reinforcing effect of cocaine remains unknown. This study was undertaken to examine effects of a long-term dosing regimen with selective MAOIs on cocaine and food reward. MATERIALS AND METHODS Since single dose of clorgyline (2 mg/kg), deprenyl (1 mg/kg), and(More)
