The effects of diazepam quipazine, lysergic acid diethylamide (LSD), and 2,5-dimethoxy-4-methylamphetamine (DOM) were examined on a conditioned suppression paradigm. Food-deprived rats were trained to drink a liquid diet from a tube. Subsequently, intermittent 7-s tones were presented during the daily 10-min sessions, the tube being electrified during the last 5 s of each tone. The subject...

Indole and phenethylamine-type hallucinogenic drugs were studied in an FR-40 operant behavioral procedure programmed to quantify "pausing,"-a behavioral disruption somewhat specific to hallucinatory drug effects. LSD, DOM, DMT and mescaline showed a potency ratio to produce pausing that is well correlated with the hallucinatory potencies of these agents in man. Furthermore, combinations of the...

Pairs of male Sprague-Dawley rats were administered mescaline, lysergic acid diethylamide (LSD), psilocin, N,N-dimethyltryptamine (DMT), 3,4-dimethoxyphenylethylamine (DMPEA), or 5-hydroxydopamine (5-OHDA) IP prior to being placed in a shock-elicited aggression situation. When foot shock was delivered, controls struck each other with their forepaws, but never engaged in either biting or...

Phencyclidine (1-[1-phenylcyclohexyl]piperidine, PCP, hog, sheets, angel dust, Sernylan, and many other common names) is a primate anesthetic that has emerged as a common drug of abuse and as a medical emergency problem during the past few years. Phencyclidine abuse is primarily a youthful activity. It is associated with multiple clinical states, an unusual amount of aggressive behavior, and a...

A simplified method of studying the surfacing reaction of goldfish to hallucinogens is described. Goldfish weighing up to three grams are injected intracranially. Employing this method, d-lysergic acid diethylamide (LSD-25), d-2-acetyl lysergic acid diethylamide (ALD-52), 1-methyl d-lysergic acid butano-lamide (UML-491), and 5-methoxy dimethyl tryptamine (5-MEO-DMT) were found to be as...

Rats were tested for shock elicited fighting under various doses of N,N-dimethyltryptamine (0.12, 0.25, 0.50, 1.0, 4.0, 8.0 mg/kg) and 5-methoxy-N,N-dimethyltryptamine (0.06, 0.12, 0.5, 2.0 mg/kg). Both drugs produced an inhibition of fighting at higher doses but no significant effects at lower doses. The effects of these drugs on shock elicited fighting, as well as on other behaviors, thus...

To say the least, the literature on indole hallucinogens and schizophrenia is confusing. This is because investigators who have access to schizophrenic patients do not have sophisticated gas chromatographic and mass spectrographic facilities, and those chemically sophisticated researchers who have such analytic facilities do not have access to a suitable patient research population. This...

Recordings of the electroencephalogram (EEG) and the electromyogram (EMG) were collected continuously from rats equipped with permanent cortical and temporalis muscle electrodes. Automatic injections of mescaline were administered through indwelling i.p. cannulas at an initial dose of 30 mg/kg every 6 hrs for the first 2 days. This dose was then increased to 60 mg/kg 6 hr which was given for...

D-lysergic acid diethylamide (LSD) displays (1) the phenylethylamine pattern present in mescaline, cyclazocine and catecholamines and (2) the 4-substituted tryptamine structure of psilocybin which is a serotonin analog. Hence (a) Naloxone--a blocker of the LSD-like side effects of cyclazocine--should (and does) block effects of LSD, and (b) cross-tolerance may be present between LSD and...

Several different molecular conformations of psychedelic drugs have been proposed to explain the very similar effects of drugs with markedly divergent chemical structures, such as mescaline andd-lysergic acid diethylamide (LSD). In some of these models, the α-carbon of methoxyamphetamine psychedelics approximates the asymmetric carbon No. 5 of LSD predicting that the (-) "R" isomer of the...
