The hallucinogenic indoleamine drugs N,N-dimethyltryptamine (N,N-DMT), psilocybin, bufotenin, 5-methoxy-N,N-dimethyltryptamine, and N-methyltryptamine, increased rat plasma prolactin (PRL) levels. The increase in plasma PRL produced by N,N-DMT, psilocybin, and bufotenin was inhibited by methysergide, a serotonin receptor blocker. Parachlorophenylalanine (PCPA), an inhibitor of serotonin...

The effects of several indoleamines and phenethylamines were studied in the chronic spinal dog and compared with two standard drugs, LSD and amphetamine. In the nontolerant chronic spinal dog, their effects on a variety of physiologic and behavioral functions were measured in untreated dogs, as well as dogs treated with certain antagonists. The effects of the antagonists phenoxybenzamine and...

The incidence and quantities of dimethyltryptamine and O-methylbufotenine were studied in the cerebrospinal fluid of patients suffering acute schizophrenic illnesses and in surgical and neurological control groups. Some schizophrenic patients have higher levels of both amines than do controls, though the differences in distribution did not reach statistical significance in the sample studied....

The dopaminergic actions of various hallucinogenic drugs were assessed by examining their effects on turning behavior in rats with unilateral 6-hydroxydopamine lesions of the nigro-striatal pathway. LSD (0.1 and 0.2 mg/kg) produced strong contralateral turning, indicating that it is a potent dopamine receptor agonist, while BOL (5 mg/kg), a non-hallucinogenic congener of LSD, was found to be a...

At a dose as low as 1 microgram per kilogram of body weight, lysergic acid diethylamide (LSD) significantly decreased the suppressive effect of electric shock on licking behavior of the rat. Attenuation of punishment was also obtained with mescaline, but neither dimethyltryptamine nor Δ 9 -tetrahydrocannabinol was active in this test. Cyproheptadine and α-propyldopacetamide, drugs that...

Keeping biochemical determinations and clinical judgements independent, the authors investigated three aspects of the transmethylation hypothesis. They found that 26 acutely schizophrenic patients were no more likely to have bufotenine or N,N-dimethyltryptamine present in urine or elevated serum indolethylamine N-methyltransferase activity than 10 normal control subjects. The authors conclude...

Investigations were carried out on the interactions of the hallucinogenic drug, D-lysergic acid diethylamide (D-LSD), and other serotonin antagonists with catecholamine-sensitive adenylate cyclase systems in cell-free preparations from different regions of rat brain. In equimolar concentration, D-LSD, 2-brono-D-lysergic acid diethylamide (BOL), or methysergide (UML) strongly blocked maximal...

Normal mental functions can be disrupted by many kinds of drugs. Hallucinogens are of special interest because of their ability to impair higher centers without producing substantial effect on other functions of the central nervous system. While the mechanism of action of hallucinogens has not been clarified, the striking structural resemblance between certain of these agents and several...

The actions of 5‐methoxytryptamine (5‐MeOT), N,N ‐dimethyltryptamine (DMT), 5‐hydroxy‐ N,N ‐dimethyltryptamine (bufotenine, 5‐HODMT) and 5‐methoxy‐ N,N ‐dimethyltryptamine (5‐MeODMT), and their interactions with 5‐hydroxytryptamine (5‐HT), acetylcholine, (–)‐noradrenaline, and glutamate were studied by microiontophoresis on single neurones in the brain stem of rats anaesthetized with urethane...
