Using the micronucleus test as a screening method for mutagenic activity, no significant increase in the number of micronuclei was found when LSD, psilocybin or delta 9-THC were administered in 3 logarithmically increasing doses to mice, Azathioiprine (Imuran), given as a positive control, caused a statistically significantt increase in the micronucleated cells.
Severe ocular malformations, including microphthalmos, intraocular cartilage, cataract, persistent hyperplastic primary vitreous, and retinal dysplasia, occurred in a premature baby girl. The mother had ingested LSD during the first trimester of pregnancy. To our knowledge, this is the third case reported of ocular teratogenesis associated with maternal LSD ingestion. Further cases must be...
AbstractDurch Hydrierung von LSD (I) mit Wasserstoff an Pd/Cwird Dihydrolysergsäurediethylamid (II) erhalten, während die Hydrierung von Iso‐LSD (III) ein Gemisch aus den Dihydroverbindungen (IV) und (V) ergibt.
Some of the difficulties of trying to establish an animal model of schizophrenia are first considered. Then, after a review of the evidence on the experimental psychopathology of schizophrenia, particularly that concerned with attention and arousal, it is concluded that the core feature which needs to be modeled in animals is some aspect of "input dysfunction." It is argued that, of the...
D-Lysergic acid diethylamide and D-2-bromolysergic acid diethylamide are competitive antagonists of the histamine activation of adenylate cyclase [ATP pyrophosphate-lyase (cyclizing); E.C. 4.6.1.1] in broken cell preparations of the hippocampus and cortex of guinea pig brain. The adenylate cyclase is linked to the histamine H2-receptor. Both D-lysergic acid diethylamide and D-2-bromolysergic...
Over a five-year period, thirty patients in a maximum security mental hospital were treated with LSD (500 mcmg. I.M.). Three different styles of interviewing procedure evolved with experience: a medical model, a “responsible street model”, and a non-directive model. The interviewer's orientation appeared to significantly affect the patient's perception of the LSD experience. Since it was felt...
A fixed-ratio schedule of water reinforcement (FR-10) was used to examine the relative contributions of pharmacological and behavioral mechanisms in the development of tolerance to the disruptive effects of LSD and mescaline in the rat. Rats treated daily with LSD or mescaline before operant testing developed tolerance to the impairement of responding, while rats treated daily after each...
In the course of examining the complete dose-response relationship for the behavioral effects of LSD in the cat, we discovered that, in addition to large increases in investigatory and hallucinatory-like responses, two behaviors, not previously reported, are emitted with a high probability under LSD. Beginning from a baseline of essentially zero in saline-treated animals, limb flicks and...
SYNOPSIS Oral treatment of phantom limb pain in five males and two females ranging in age from 25 to 78 years with sub‐hallucinogenic doses of Iysergic acid diethyImaide (LSD‐25) resulted in improvement in pain in five patients and reduction in use of analgesics. In two of the five patients improvement was striking and in the other three, pain and analgesic use were reduced moderately. LSD...
