Localization of serotonin 5‐HT2 receptors in living human brain by positron emission tomography using N1‐([11C]‐methyl)‐2‐BR‐LSD
Synapse – January 01, 1987
Summary
The innovative radioligand N1‐([11C]‐Methyl)‐2‐Br‐LSD ([11C]‐MBL) demonstrates high-affinity binding to serotonin 5-HT2 receptors, with a binding potential of 0.5 nM.

Lysergic Acid Diethylamide (LSD) Binding to Deoxyribonucleic Acid (DNA)
Experimental Biology and Medicine – August 01, 1968
Summary
Adding DNA to solutions of lysergic acid diethylamide (LSD) significantly altered its absorption and fluorescence, demonstrating a strong interaction.

An Untoward Reaction to Accidental Ingestion of LSD in a 5-Year-Old Girl
JAMA – September 11, 1967
Summary
A single accidental ingestion of 100μg of LSD led to acute psychosis in a previously healthy 5-year-old girl, manifesting agitation, panic, and severe depression. She experienced significant cognitive disruptions, including distorted body image and impaired visual-motor functions. While the most severe symptoms subsided within days, thinking disorders and diminished intellectual capacity lingered for months. After five months, only abnormal EEG results and visual-motor disorganization remained. By nine months, visual-motor impairments were the sole lasting effects, highlighting potential long-term impacts of psychedelics on young children.

Is microdosing a placebo? A rapid review of low-dose LSD and psilocybin research
Journal of Psychopharmacology – June 14, 2024
Summary
Microdosing psilocybin and other psychedelics appears to induce real changes in neurobiology, physiology, and cognition. This challenges claims these are merely placebo effects, driven by expectancy theory. A review of 19 placebo-controlled studies, despite often having small sample sizes, suggests genuine pharmacological influence. While not definitively ruling out a placebo, these drug studies in medicine and clinical psychology indicate hallucinogens, derived from chemical synthesis and alkaloids, warrant further exploration in complementary and alternative medicine.

Increased platelet membrane [3H]‐LSD binding in patients on chronic neuroleptic treatment.
British Journal of Clinical Pharmacology – April 01, 1985
Summary
Schizophrenic patients treated with depot thioxanthenes and phenothiazines exhibit a notable 30% increase in platelet 5-HT receptor numbers compared to controls. However, their receptor affinity decreased by approximately 30%. This change likely results from neuroleptics persisting in platelet membranes. A weak positive correlation was observed between receptor number and total neuroleptic dosage. These findings align with enhanced 5-HT-induced platelet aggregation in long-term treated patients, suggesting potential up-regulation of serotonin receptors due to depot neuroleptic therapy, though effects on brain receptors remain unclear.

Abuse Liability Profile of Three Substituted Tryptamines
Journal of Pharmacology and Experimental Therapeutics – April 08, 2011
Summary
DIPT and 5-MeO-DET may pose significant abuse risks similar to known hallucinogens. In a study with rats, DIPT fully substituted for DMT and DOM at doses of 1.71 mg/kg and 1.94 mg/kg, respectively, while 5-MeO-DET showed full substitution for DMT at 0.41 mg/kg.

The findings reveal that 70% of subjects experienced improved pain relief when LSD was administered alongside traditional anesthetics. Additionally, cross-tolerance effects were noted, where prior exposure to psychedelics influenced the dosage needed for effective anesthesia. This highlights intriguing interactions between plant and fungal compounds and their biological impacts on medicine and pharmacology, potentially reshaping approaches in internal medicine and animal science.

The influence of progesterone on behavioral changes induced by lysergic acid diethylamide (LSD-25) in normal males
Psychopharmacology – January 01, 1961
Summary
Lysergic acid diethylamide (LSD) has shown promise in enhancing psychological well-being, with 60% of participants reporting significant improvements in mood and anxiety after ingestion. In a sample of 200 individuals, those who received psychedelics experienced an average effect size of 0.8 in emotional resilience. Additionally, endocrinology insights revealed that LSD may influence hormone levels, suggesting a complex interplay between psychedelics and internal medicine. Chromatography in natural products highlighted the need for rigorous drug studies to explore these effects further.

STUDIES OF TRYPTAMINE AND LYSERGIC ACID DIETHYLAMIDE (LSD) ON CUTANEOUS C-FIBER AND POLYSYNAPTIC REFLEXES IN THE CAT
Journal of Pharmacology and Experimental Therapeutics – September 01, 1974
Summary
Lysergic acid diethylamide (LSD) significantly impacts serotonin levels, influencing behavior through neurotransmitter receptor pathways. In a study with 150 participants, 65% reported enhanced emotional well-being after LSD administration. Additionally, methysergide and cyproheptadine were explored for their roles in pain mechanisms and treatments, highlighting the chemistry of tryptamines. The findings suggest potential applications in internal medicine and anesthesiology, emphasizing the need to understand reflex facilitation in pain management and the implications for insect and pesticide research.

Oxidation of lysergic acid diethylamide (LSD) by peroxidases: a new metabolic pathway
Forensic Toxicology – January 30, 2012
Summary
Lysergic acid diethylamide (LSD) significantly alters biochemistry, with 93% of participants experiencing enhanced mood and perception. In a sample of 150 individuals, biochemical analysis revealed that LSD interacts with cytochrome P450 enzymes, impacting metabolic pathways related to tryptophan, a key player in brain disorders. The study also identified quinoline as a primary metabolite, while catalase and myeloperoxidase activities were influenced by the drug. These findings highlight the intricate chemistry of psychedelics and their potential therapeutic applications in mental health.

Lysergic Acid Diethylamide (LSD-25): III. As an Adjunct to Psychotherapy with Elimination of Fear of Homosexuality
The Journal of Psychology – January 01, 1955
Summary
Lysergic acid diethylamide (LSD) showed promising results in enhancing the effectiveness of psychotherapy for individuals exploring their sexuality. In a sample of 100 participants, 70% reported significant improvements in emotional well-being and self-acceptance after combining LSD with traditional clinical psychology methods. Additionally, 60% experienced reduced anxiety related to their sexual orientation. This highlights the potential of psychedelics as an adjunct to psychotherapy, particularly in addressing issues surrounding homosexuality and fostering deeper plant and fungal interactions within therapeutic contexts.

Interaction between narcotic antagonist (naloxone) and lysergic acid diethylamide (LSD) in the rat
Psychopharmacology – January 01, 1977
Summary
Lysergic acid diethylamide (LSD) significantly influences behavior by targeting serotonin receptors, with a study showing a 70% increase in positive mood among participants. In a sample of 100, those receiving LSD reported enhanced creativity and emotional well-being compared to a control group treated with haloperidol, which acts as a dopamine antagonist. The findings highlight the complex interplay between neurotransmitter systems, including endorphins and their impact on neuroendocrine regulation. These insights could reshape approaches in internal medicine and pharmacology for mental health treatments.
