Using a [3H]‐lysergic acid diethylamide [(3H]‐LSD) binding technique, platelet 5‐hydroxytryptamine (5‐HT) receptor number and affinity were compared in schizophrenics treated with depot thioxanthenes and phenothiazines and controls. There was an approximately 30% increase in platelet receptor number (Bmax) in the patient group. There was a decrease in affinity (increase in Kd) of about 30% in...

Tryptamine has been widely accepted as a trace amine in brain, and several reviews of its metabolism, regional localization in brain, and possible neuroregulatory functions have been published (Jones, 1982; Juorio and Durden, 1984). Other endogenously synthesized indoleamines have received only minimal attention in several review monographs and symposium volumes devoted to the trace amines...

Specific binding of [3H]lysergic acid diethylamide (LSD) to human platelet membranes, as defined by 300 nM spiperone, was saturable over the concentration range of 0.25-2.5 nM [3H]LSD. At 0.5 nM [3H]LSD the half-time for association at 37 degrees C was 56 min, half-time for dissociation was 173 min, and the kinetically derived affinity was 0.24 nM. In 19 control subjects equilibrium binding...

The serotonin precursor L-5-hydroxytryptophan reversed the symptoms of a 23-year-old man suffering from LSD-induced psychosis who participated in a randomized, double-blind crossover study of the drug and a placebo. This finding is compatible with the speculation that some LSD-induced psychotic disorders may be caused by a relative deficiency of CNS serotonin.

The effect of zotepine, a new neuroleptic, on head-twitch induced by L-5-hydroxytryptophan (L-5HTP), mescaline and 2,5-dimethoxy-4-methylamphetamine (DOM) in mice and rats was compared with that of known neuroleptics and the serotonin receptor blocker cyproheptadine. Among the neuroleptics tested, zotepine and halo-peridol produced potent inhibitory effects on head-twitch induced by these three...

Many observers have noted similarities between dreams, hallucinogenic drug states, and schizophrenia. In the present article, certain fundamental areas of convergence between the three states are described. Consideration is given to the hallucinogenic drug model of psychosis: the reasons for its initial attractiveness, and the reasons for its current disfavor. The concept of ego boundaries is...

The nonhallucinogenic ergot derivative lisuride exerts many pharmacological effects that are similar to those of its hallucinogenic congener, lysergic acid diethylamide (LSD). Animals trained to discriminate between the presence of one drug and the other can be used to differentiate the actions of these compounds on a neuronal level. The discriminative stimulus effect of LSD (the LSD cue) is...

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...

The purpose of the present study was to determine the role of central 5-hydroxytryptamine (5-HT) neuronal systems in the effects of d-lysergic acid diethylamide (LSD), 2,5-methoxy-4-methylamphetamine (DOM), pentobarbital (PB) and methaqualone (MQ) on punished responding in rats. Water-deprived rats were trained to drink from a tube that was electrified at intervals (variable interval 21 sec;...
