Research

Initial characterization of PMMA as a discriminative stimulus.

Pharmacology, Biochemistry, and Behavior 1997 Richard A Glennon, R Young, Małgorzata Dukat et al. 48 citations

The phenylisopropylamine PMMA or N-methyl-1-(4-methoxyphenyl)-2-aminopropane, a structural hybrid of paramethoxyamphetamine (PMA) and methamphetamine, has been previously shown to unexpectedly lack amphetamine-like or hallucinogen-like stimulus properties in animals. For example, in tests of stimulus generalization, neither a (+)amphetamine stimulus nor a DOM stimulus generalized to PMMA. It...

[Hallucinogen induced psychic disorders. Subjective experiences, psychopathology and differential diagnosis].

Fortschritte der Neurologie · Psychiatrie December 1996 L Hermle, Euphrosyne Gouzoulis‐mayfrank, M Spitzer

The concepts of intoxication, intoxication psychosis, and drug-induced psychosis are frequently used to refer to psychopathological states caused by the intake of hallucinogenic substances. The considerable increase of intoxications with substances of the chemical class of amphetamines (in particular, "Ecstasy") in western countries should cause major concern. Moreover, the number of...

Ulrike Wiethaus, Ecstatic Transformation: Transpersonal Psychology in the Work of Mechthild of Magdeburg. Syracuse University Press, 1996

Medieval Feminist Newsletter September 1, 1996 Amy Hollywood

Ulrike Wiethaus' ambitious goal is to make medieval mysticism intellectually accessible to a modem western audience (2).To do this, she draws analogies between modem psychologies open to the existence and significance of "altered states of consciousness" and the accounts of ecstasies and visions within Mechthild of Magdeburg's The Flowing Light of the Godhead.The study is divided into two...

…such as ketamine

BMJ August 17, 1996 David Shewan, Phil Dalgarno, Leslie A. King 14 citations

EDITOR,—There is increasing concern over the toxic1 and neurodegenerative2 effects of ecstasy, and further research is clearly required. Potential hazards can also, however, arise through use of tablets sold as ecstasy that contain substances other than ecstasy, such as ketamine. Ketamine is an anaesthetic agent with a rapid action that has medical and veterinary applications. Drug users who...

5-HT modulation of auditory and visual sensorimotor gating: I. Effects of 5-HT releasers on sound and light prepulse inhibition in Wistar rats.

Psychopharmacology March 1996 J H Kehne, R A Padich, T C McCloskey et al.

Increasing evidence suggests an important role for serotonin (5-HT) neurons in the etiology and treatment of schizophrenia. The prepulse inhibition paradigm is used as a model for sensorimotor gating processes that are disrupted in schizophrenia. The present study assessed the general role of 5-HT in modulating auditory and visual prepulse inhibition in Wistar rats. A general overactivation of...

5-HT modulation of auditory and visual sensorimotor gating: II. Effects of the 5-HT2A antagonist MDL 100,907 on disruption of sound and light prepulse inhibition produced by 5-HT agonists in Wistar rats.

Psychopharmacology March 1996 R A Padich, T C McCloskey, J H Kehne

Increasing evidence suggests an important role of 5-HT, and 5-HT2A receptors in particular, in the etiology and treatment of schizophrenia. The prepulse inhibition paradigm is used as a model for sensorimotor gating processes that are disrupted in schizophrenia. The present study used the selective serotonin2A (5-HT2A) antagonist and putative antipsychotic agent MDL 100,907 to evaluate the...

Reinforcing effects of certain serotonin-releasing amphetamine derivatives.

Pharmacology, Biochemistry, and Behavior January 1996 D Marona-Lewicka, G S Rhee, J E Sprague et al.

The present study was designed to characterize further the rewarding and aversive properties of 3,4-methylenedioxymethamphetamine (MDMA), the alpha-ethyl homologue of MDMA (MBDB), fenfluramine, and the selective serotonin releasing agent 5-methoxy-6-methyl-2-aminoindan (MMAI) using the conditioned place preference paradigm (CPP). Extracellular dopamine (DA) and its metabolite DOPAC were also...

GEPTAKHOR

Experiment 1996 Viktor Teider 42 citations

In experimental animals, administration of 3,4-methylenedioxymethamphetamine (MDMA, Ecstasy) leads to extensive, but incomplete, loss of 5-hydroxytryptamine (5-HT) innervation in the brain. Here, we report the effects of MDMA on 5-HT neuronal function measured in the rat in vivo using electrophysiological and microdialysis techniques. Two weeks after administration of an established neurotoxic...

The Higher Powers: Fred M. Smith and the Peyote Ceremonies

Dialogue: A Journal of Mormon Thought December 1, 1995 Shelby M. Barnes

Frederick Madison Smith was third president and prophet of the Reorganized Church of Jesus Christ of Latter Day Saints.Son of Joseph III and grandson of Joseph the Martyr, Fred M., as he was generally known, came to lead the Reorganization in 1915.Smith was a highly educated man interested in the relationship between science and religion.His interest led him to experiment with the religious...

Behavioural and neuroendocrine responses to D-fenfluramine in rats treated with neurotoxic amphetamines

Journal of Psychopharmacology May 1, 1995 Hugh Series, Marisa Le Masurier, Sarah E. Gartside et al. 13 citations

The amphetamine derivatives p-chloroamphetamine (pCA), 3,4-methylenedioxymethamphetamine (MDMA, 'Ecstasy') and D-fenfluramine can, if given repeatedly in high doses to rats, produce a degeneration of serotonergic nerve terminals which we have previously shown to result in a reduction in D-fenfluramine-evoked release of 5-HT in vivo. It is therefore possible that fenfluramine-evoked responses...
