Bromo-DMA: the Australasian hallucinogen?

Australian & New Zealand Journal of Psychiatry September 1983 N Buhrich, G Morris, G Cook

If the frequency of seizures by police of hallucinogens reflects the frequency with which various hallucinogens are ingested in Australasia, most toxic states resulting from hallucinogen abuse are due to Bromo-DMA and not to LSD as is commonly reported by the subjects. Two cases of intoxication with the new hallucinogen, Bromo-DMA, are reported. Both recovered within 24 hours following...

Influence of psychotomimetics and lisuride on synaptosomal dopamine release in the nucleus accumbens of rats.

European Journal of Pharmacology September 1, 1983

In superfusion experiments with a crude synaptosomal fraction from the nucleus accumbens of rats, lysergic acid diethylamide, mescaline and N,N-dimethyltryptamine (representing different chemical classes of psychotomimetics) produced a concentration-related inhibition of K+-evoked [3H]dopamine release whereas spontaneous release remained unchanged. The nonpsychotomimetic ergoline lisuride...

Antagonism of the effects of the hallucinogen DOM and the purported 5-HT agonist quipazine by 5-HT2 antagonists.

European Journal of Pharmacology July 1, 1983

Rats trained to discriminate 1.0 mg/kg of 1-(2,5-dimethoxy-4-methylphenyl)-2-aminopropane (DOM) from saline in a two-lever operant choice task were administered doses of mescaline, LSD, 5-methoxy-N,N-dimethyltryptamine (5-OMe DMT), quipazine, TFMPP and RU-24969. The DOM-stimulus generalized to the three hallucinogenic agents and to quipazine, but not to the purported serotonin agonists TFMPP or...

Raphe neurons: firing rate correlates with size of drug response.

European Journal of Pharmacology June 3, 1983 Barry L. Jacobs, J Heym, K Rasmussen 25 citations

Significant negative correlations were obtained between the spontaneous discharge rate during waking and the neural response to systemic injections of either 5-MeODMT or LSD for serotonergic neurons in the dorsal raphe nucleus, nucleus centralis superior, and nucleus raphe pallidus of unanesthetized and unrestrained cats. These data are discussed in terms of an hypothesis which accounts for...

Review of Enquiries made to the NPIS Concerning Psilocybe Mushroom Ingestion, 1978-1981

Human Toxicology April 1, 1983 J. Francis, Virginia Murray 18 citations

The historical, botanical and chemical aspects of hallucinogenic mushroom are well described (Lincoff & Mitchell, 1977; Cooper, 1980). The use of hallucinogenic mushroom stretches back as far as ancient Aztec civilisation and it has become fashionable in the West since the 1950s, with publicity from popular writers such as Aldous Huxley and Carlos Castenada (Huxley, 1976; Castenada, 1970)....

Mescaline‐induced head‐twitches in the rat: An in vivo method to evaluate serotonin S2 antagonists

Drug Development Research 1983 C. J. E. Niemegeers, Françis C. Colpaert, J.e. Leysen et al. 58 citations

Abstract An intravenous dose of 20.0 mg/kg of mescaline induced a reproducible head‐twitch response in rats. Drugs with very different pharmacological activities were tested for potential inhibition of this response. Among these drugs were a large number of serotonin antagonists, including several members of the recently described selective S 2 antagonists of which ketanserin (a potent vascular...

Behavioral effects of 5-methoxy-N,N-dimethyltryptamine and dose-dependent antagonism by BC-105.

Psychopharmacology 1983 R Young, John A. Rosecrans, Richard A Glennon 25 citations

The discriminative effects of 5-methoxy-N,N-dimethyltryptamine (5-OMeDMT) were studied in rats trained to discriminate 1.5 mg/kg or 3.0 mg/kg 5-OMeDMT from saline. A series of antagonist and generalization tests revealed that (1) antagonism of the 5-OMeDMT stimulus response by the presumed serotonin antagonist BC-105 depended on the dose of 5-OMeDMT, (2) the 5-OMeDMT stimulus generalized to...

Anorexia and hyperphagia produced by five pharmacologic classes of hallucinogens.

Pharmacology, Biochemistry, and Behavior September 1, 1982 D B Vaupel, E C Morton

The acute actions of five prototype hallucinogens administered SC on food consumption in 23 hr food deprived dogs were compared with the anorexic effect of d-amphetamine and the hyperphagic effect of sodium pentobarbital. Comparisons were made on the basis of dose-response relationships. Among the hallucinogens decreasing food intake, both LSD and atropine produced substantial anorexia, but the...

8-hydroxy-2-(di-n-propylamino)tetralin, 8-OH-DPAT, a potent and selective simplified ergot congener with central 5-HT-receptor stimulating activity

Journal of Neural Transmission September 1, 1982 S. Hjorth, A. Carlsson, P. Lindberg et al.

It was demonstrated that the simplified ergot congener 8-hydroxy-2-(di-n-propylamino)tetralin, 8-OH-DPAT, is able to elicit pronounced biochemical and behavioural alterations indicative of central serotoninomimetic activity. Since these effects are resistant to prior monoamine depletion and/or synthesis inhibition by means of reserpine and α -propyldopacetamide (H22/54), respectively, they are...

Psilocybin as a discriminative stimulus: Lack of specificity in an animal behavior model for ?hallucinogens?

Psychopharmacology February 1, 1982 Jon Koerner, James B. Appel 19 citations

Fifteen rats were trained to discriminate between the tryptamine hallucinogen psilocybin (4-phosphoryloxy-N,N-dimethyltryptamine; 1.0 mg/kg) and saline in a two-lever choice task. Dose-response and time-response curves were obtained. The psilocybin cue generalized to psilocin (the dephosphorylated congener of psilocybin) and to the prototypical indoleamine hallucinogen LSD, but not to the...
