Ecstasy [3,4-methylenedioxymethamphetamine (MDMA)] was shown to prolong the action of L-3,4-dihydroxyphenylalanine (L-DOPA) while suppressing dyskinesia in a single patient with Parkinson's disease (PD). The clinical basis of this effect of MDMA is unknown but may relate to its actions on either dopaminergic or serotoninergic systems in brain. In normal, drug-naive common marmosets, MDMA admini...

BACKGROUND The popular designer drugs 3, 4-methylenedioxymethamphetamine (MDMA) and 3, 4-methylenedioxyethylamphetamine (MDEA) can be determined in serum, whole blood, and urine, but also in vitreous humor. The latter matrix is interesting when dealing with decomposed bodies in a toxicological setting. METHODS After extraction, chromatographic separation was achieved on a narrow-bore C(18) co...

l-3,4-dihydroxyphenylalanine (l-DOPA) is the most effective treatment for Parkinson's disease, but long-term l-DOPA administration is marred by the emergence of motor complications, namely, dyskinesia and a shortening of antiparkinsonian benefit (wearing-OFF). 3,4-methylenedioxymethamphetamine (MDMA) is unique in that it exerts antidyskinetic effects and may enhance antiparkinsonian actions of ...

introduction mdma or ecstasy is a derivative of amphetamines used mostly by young people worldwide. although the acute effects of this drug are known, the effect of chronic administration is not well studied. therefor the aim of this study was to determine the effects of repeated (long term) administration of mdma on rats' memory and their hippocampal cell density. method: young adult male...

The majority of MDMA (ecstasy) recreational users also consume cannabis. Despite the rewarding effects that both drugs have, they induce several opposite pharmacological responses. MDMA causes hyperthermia, oxidative stress and neuronal damage, especially at warm ambient temperature. However, THC, the main psychoactive compound of cannabis, produces hypothermic, anti-inflammatory and antioxidan...

conclusions these results suggest a negative correlation between mdma administration and adult hippocampal neurogenesis. results our results showed that mdma administration caused a decrease in neun expression in the experimental group compared with the control group. objectives due to the effect of neurogenesis on memory and learning, in this study, we investigated the effects of mdma on neun ...

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 mdma...

are examples of interoceptive cues which enable experienced users to distinguish the effects of MDMA from those of other drugs. Serotonin neurotransmission positively modulates the release of oxytocin into plasma [2]. To test the hypothesis that oxytocin receptor activation contributes to the interoceptive cues of MDMA in male and female rats, two peptidic oxytocin receptor ligands, the agonist...

The main 3, 4-methylenedioxymethamphetamine (MDMA)-induced adverse effect is disruption of normal thermoregulation leading to life threatening hyperthermia which is exacerbated by high ambient temperature and linked to chronic neurotoxicity [1-3]. Although the focus of the majority of research on MDMA-induced loss of thermoregulation has been on brain serotonergic and dopaminergic systems, resu...
