Abstract:

Se presentan 35 observaciones clínicas de jóvenes que usaron drogas alucinógenas durante dos a cuatro años en su mayoría. La proporción de varones era el triple en comparación con las mujeres, casi todos procedían de hogares bien integrados y pertenecían a un nivel socio-económico alto o mediano. Las drogas empleadas fueron marihuana, LSD, barbitúricos, mescalina, afetamina, metaqualona y alcohol, en diversas combinaciones. La totalidad de estos jóvenes presentaron signos de perturbaciones psicológicas, generalmente disturbios de la personalidad, antes de iniciarse en el uso de alucinógenos. E

El cactus “San Pedro Macho” (Echinopsis peruviana o también conocido como Trichocereus peruviana) debe en parte su nombre y su importancia a su similaridad, tanto taxonómica como en su contenido de alcaloides, con el muy conocido cactus “San Pedro Hembra” (Echinopsis pachanoi) o comúnmente denominado “San Pedro”, el cual es la especie más importante entre las plantas empleadas en Medicina Tradicional (MT) en el norte del Perú.

Abstract:

Este artigo propõe uma tradução e um comentário do episódio dos Lotófagos na Odisseia (IX, 82-104), atentando tanto para sua organização interna enquanto episódio de viagem com uma cena típica de hospitalidade (resumida apenas à oferta de comida), quanto para sua posição e especificidade no conjunto das viagens maravilhosas de Odisseu (cantos IX a XII) e no conjunto da Odisseia. Ele tenta definir os significados possíveis de lōtós (“lótus”), tais como apresentados por Heródoto e Teofrasto, em confronto com os poucos dados presentes na Odisseia (convergindo em ser ele uma planta não cultivada e

Abstract:

Se presentan en esta comunicación los primeros resultados de un ensayo con el azacyclonol en algunas reaccionas psicóticas agudas. El azacyclonol es una de las drogas más recientes para el tratamiento de las psicosis. Tiene acción sobre el sistema nervioso central, inhibiendo probablemente la serotonina y por tanto produce efectos similares a la reserpina y a la clorpromazina. La actividad fundamental consiste en que anula las alteraciones clínicas y bio-eléctricas producidas por las drogas alucinóqenos (ácido lisérgico y mescalina). En diversas psicosis tóxicas y en reacciones esquizofrénicas

Abstract:

Background: In recent years, there has been increasing scientific interest in the effects and pharmacology of serotonergic hallucinogens. While a large amount of experimental work has been conducted to characterize the behavioral response to hallucinogens in rodents, there has been little systematic investigation of mescaline and its analogs. The hallucinogenic potency of mescaline is increased by α-methylation and by homologation of the 4-methoxy group but it not clear whether these structural modifications have similar effects on the activity of mescaline in rodent models. Methods: In the pr

Abstract:

The purpose of this study was to investigate samples of commercial over-the-counter products purported to contain extracts from peyote cactus (Lophophora williamsii), a vulnerable species. Samples were extracted with organic solvent and then washed to remove impurities. The extracts of these products were subjected to an analysis by real-time mass spectrometry (DART-MS) to determine the presence or absence of the alkaloid mescaline (3,4,5-trimethoxyphenethylamine). High-performance liquid chromatography (HPLC) was used to determine mescaline concentrations in the samples and to provide quantit

Abstract:

Lophophora williamsii, peyote, is a small cactus growing to approximately 10 cm in diameter with a flat to dome-shaped spineless crown with fissures or ribs that develop following the Fibonacci series and whose numbers indicate relative degree of maturing. In this study crown tissue of 30 wild-collected specimens was analyzed to determine whether there was a correlation between the concentration of the primary alkaloid mescaline in crown tissue with the average diameter of the crown. We also compared mescaline concentration in three groups of ten individuals: 5 ribs (juvenile stage), 8 ribs (i

Abstract:

A unifying mechanism for abused drugs has been proposed previously from the standpoint of electron transfer. Mescaline can be accommodated within the theoretical framework based on redox cycling by the catechol metabolite with its quinone counterpart. Electron transfer may play a role in electrical effects involving the nervous system in the brain. This approach is in accord with structure activity relationships involving mescaline, abused drugs, catecholamines and etoposide. Inefficient demethylation is in keeping with the various drug properties, such as requirement for high dosage and slow

Abstract:

Background: Mescaline (3,4,5-trimethoxyphenethylamine), mainly found in the Peyote cactus (Lophophora williamsii), is one of the oldest known hallucinogenic agents that influence human and animal behavior, but its psychoactive mechanisms remain poorly understood. Objective: This article aims to fully review pharmacokinetics and pharmacodynamics of mescaline, focusing on the in vivo and in vitro metabolic profile of the drug and its implications for the variability of response. Methods: Mescaline pharmacokinetic and pharmacodynamic aspects were searched in books and in PubMed (U.S. National Lib
