...Fabrizio Schifano; John Corkery; Vinesha Naidoo; Adenekan Oyefeso; Hamid Ghodse Background/Aims: Despite being amphetamine derivatives, MDMA and its analogues show a number of clinical pharmacological differences with respect to both amphetamine (AMP) and methylamphetamine (METH). We aimed here...

... aftereffect among ecstasy users, but only in a subset that were recently abstinent from amphetamines. The current study examined the effects of ecstasy use, cannabis use and their interacting effect on the magnitude of the tilt aftereffect among participants with no recent history of amphetamine consumption...

...Jonathan J. Lipman; Stephen Tolchard The effects of morphine (5 mg/kg) and amphetamine (5 mg/kg) were examined on relative regional cerebral glucose uptake (RrCGlu), surveyed in 20 brain areas in the rat. No relationship was found between drug effects on the cortical RrCGlu and the quantitative...

...Yn-Ho Huang; Shih-Jen Tsai; Ying-Chou Wang; Meng-Fen Yu; Yu-Chih Yang; Cho-Boon Sim Behavioral sensitization elicited by repeated administration of amphetamine does not fully develop until a period after discontinuation of amphetamine, but then persists undiminished for a long time. This experiment...

...Filipe Arriaga; Christine Dugovic; Albert Wauquier The effects of lithium on the potentiation of d -amphetamine-induced hyperlocomotion were evaluated in rapid eye movement (REM) sleep deprived rats. Under control conditions, pretreatment with lithium during 7 days did not modify...

...Minda R. Lynch; Hans-Georg Kuhn; Robert J. Carey As low-dose amphetamine stimulation of locomotor activity in the rat depends upon a mesolimbic dopaminergic substrate, neuroleptic antagonism of this behavior has been suggested as a model for studying anti-psychotic activity. Animals in the present...

...Roy J. Mathew; William H. Wilson Changes in regional cerebral blood flow and behavioral and physiological indices were monitored after intravenous administration of d -amphetamine sulfate and placebo in groups of patients with schizophrenia and normal volunteers. Amphetamine administration...

...B. Lerer; M. Globus; E. Brik; R. Hamburger; R.H. Belmaker Chronic lithium (Li) administration to rats was found to inhibit the hyperactivity induced by 0.5 mg/kg d -amphetamine but not that induced by 1.0 mg/kg d -amphetamine. Contradictory results on the ability of Li to inhibit amphetamine...

...Michael Budek; Amiram I. Barkai; David L. Brown; Ronald R. Fieve Changes of hippocampal EEG activity resulting from administration of d -amphetamine were investigated in rabbits before, during and after chronic treatment with haloperidol. Cross-zero analysis of EEG data showed that chronic...

... to walk in a slowly rotating treadwheel. The level of vigilance recorded under these conditions could be shifted by amphetamine, 1.0 mg/kg p.o., to a higher state of arousal, as shown by a reduction in power in all frequency bands, and by diazepam, 0.3 mg/kg p.o., to a lower state of arousal, as indicated...

Plotnikoff Both thyrotropin-reieasing hormone (TRH) and amphetamine antagonize pentobarbital. They are more effective in the day than at night. This is true...

...A.C. Parrott MDMA (3,4-methylenedioxymethamphetamine) or ‘ecstasy’ is a ring-substituted amphetamine derivative, which is widely used as a recreational drug, most particularly at dances and raves. Around 80–95% of dancers/ravers report using ecstasy/MDMA, compared to 5–15% of young people...

...Adriana Lourenço da Silva; Anselmo Hoffmann; Marcelo O. Dietrich; Oscar P. Dall’Igna; Diogo O. Souza; Diogo R. Lara N-methyl- D aspartate (NMDA) antagonists, such as MK-801, and the dopamine indirect agonist amphetamine are pharmacological models used for the evaluation of putative new treatments...
