A case of a patient with intracranial haemorrhage thought to have been associated with ingestion of 'Ecstasy' [3-4 methylenedioxymethamphetamine (MDMA)] is presented. The case illustrates the importance of drug analysis in cases involving illicit drug use.

Previous research in our laboratory found that repeated exposure of adolescent rats to 3,4-methylenedioxymethamphetamine (MDMA) impaired working memory and reduced anxiety. The present experiment extended these findings by investigating the physiological, behavioral, and neurotoxic effects of a modified MDMA treatment regimen. Male Sprague-Dawley rats received 5 mg/kg of MDMA hourly for a perio...

3,4-methylenedioxymethamphetamine (MDMA) is an illicit drug that has been associated with serotonergic axonal degeneration in animals. This study evaluates neurochemical abnormalities in recreational MDMA users. Twenty-two MDMA users and 37 normal subjects were evaluated with magnetic resonance imaging (MRI) and proton magnetic resonance spectroscopy ((1)H MRS) in the mid-frontal, mid-occipital...

The recreational drug, (+/-)3,4-methylenedioxymethamphetamine (MDMA, 'Ecstasy'), is a potent serotonin (5-HT) neurotoxin in animals. Whether humans who use MDMA incur 5-HT neural injury is unknown. The present studies utilized positron emission tomography (PET) in conjunction with the 5-HT transporter ligand, [11C]McN-5652 to assess the status of brain 5-HT neurons in human MDMA users. Like non...

The authors found that striatal levels of serotonin and those of its metabolite 5-hydroxyindoleacetic acid were severely depleted by 50 to 80% in brain of a chronic user of methylenedioxymethamphetamine (MDMA) whereas concentrations of dopamine were within the normal control range. Our data suggest that MDMA exposure in the human can cause decreased tissue stores of serotonin and therefore some...

Estimation of illicit drug use on a community level by wastewater-based epidemiology (WBE) is both an objective and reliable way to establish near real-time results. Wastewater samples were collected at eleven timepoints in Reykjavik from 2017 2020. The commonly abused drugs Iceland (amphetamine, methamphetamine, 3,4-methylenedioxymethamphetamine (MDMA), cocaine, cannabis) was estimated. Solid ...

Methylenedioxymethamphetamine (MDMA) has previously been shown to produce a positive conditioned place preference (CPP) among rats. Here the effects of doses of a specific 5-HT3 antagonist, MDL72222, on MDMA's ability to produce a CPP were assessed. A dose of MDL72222 (0.03 mg/kg) blocked the establishment of a MDMA CPP. These results support the suggestions that compounds affecting the 5-HT3 r...

Methylenedioxymethamphetamine (MDMA) is generally described as non-addictive. However, this report describes three cases in which criteria for dependence were met. A wider understanding that MDMA can be addictive in rare cases is important as very heavy use may cause lasting neuronal changes. This risk could be reduced with effective identification and treatment of dependent persons. In one cas...

Background: Ecstasy or 3-4, methylenedioxymethamphetamine (MDMA), as an amphetamine derivate, could lead to learning and memory impairment. Objectives: As the hippocampus is responsible for learning and memory, herein we evaluated acute and chronic effects of MDMA on the structure of the hippocampus. Materials and Methods: Male Wistar rats (200-250 g) received single or multiple injections of M...

INTRODUCTION Exposure to 3-4, methylenedioxymethamphetamine (MDMA) leads to cell death. Herein, we studied the protective effects of ginger on MDMA- induced apoptosis. METHODS 15 Sprague dawley male rats were administrated with 0, 10 mg/kg MDMA, or MDMA along with 100mg/kg ginger, IP for 7 days. Brains were removed to study the caspase 3, 8, and 9 expressions in the hippocampus by RT-PCR. Dat...
