The neurotoxicity of (6)-3,4-methylenedioxymethamphetamine (MDMA; “Ecstasy”) is influenced by temperature and varies according to species. The mechanisms underlying these two features of MDMA neurotoxicity are unknown, but differences in MDMA metabolism have recently been implicated in both. The present study was designed to 1) assess the effect of hypothermia on MDMA metabolism, 2) determine w...
objective(s): 3, 4-methylenedioxymethamphetamine (mdma) one of the methamphetamine derivatives that affect the reproductive system, has not been well understood. many young people are consumers of drugs such as mdma that can affect their reproductive capability. apoptosis is the main mechanism for male infertility. pentoxifylline (ptx) increases camp intracellularly and reduces tumor necrosis f...
The co-administration of D-lysergic acid diethylamide (LSD; 'Acid') and 3,4-methylenedioxymethamphetamine (MDMA; 'Ecstasy'; 'XTC'), has reached a prevalence that has allowed for the street terminology 'candyflipping' to describe the combination. Internet sites indicate a significant enhancement of central effects with their simultaneous use. In this preliminary observation, male Fawn-Hooded rat...
Methylphenidate and 3,4-methylenedioxymethamphetamine (MDMA, 'ecstasy') are widely misused psychoactive drugs. Methylphenidate increases brain dopamine and norepinephrine levels by blocking the presynaptic reuptake transporters. MDMA releases serotonin, dopamine and norepinephrine through the same transporters. Pharmacodynamic interactions of methylphenidate and MDMA are likely. This study comp...
Ecstasy is a widely used recreational drug that usually consists primarily of 3,4-methylenedioxymethamphetamine (MDMA). Most ecstasy users consume other substances as well, which complicates the interpretation of research in this field. The positively rated effects of MDMA consumption include euphoria, arousal, enhanced mood, increased sociability, and heightened perceptions; some common advers...
3,4-methylenedioxymethamphetamine (MDMA; ecstasy) is a commonly abused recreational drug that causes neurotoxic effects in both humans and animals. The mechanism behind MDMA-induced neurotoxicity is suggested to be species-dependent and needs to be further investigated on the cellular level. In this study, the effects of MDMA in neuronally differentiated P19 mouse embryonal carcinoma cells have...
Oxidative and/or bioenergetic stress is thought to contribute to the mechanism of neurotoxicity of amphetamine derivatives, e.g., 3,4-methylenedioxymethamphetamine (MDMA). In the present study, the effect of MDMA on brain energy regulation was investigated by examining the effect of MDMA on brain glycogen and glucose. A single injection of MDMA (10-40 mg/kg, s.c.) produced a dose-dependent decr...
The widely abused amphetamine analog 3,4-methylenedioxymethamphetamine (MDMA, also called "ecstasy") induces hallucination and psychostimulation, as well as long-term neuropsychiatric behaviors such as panic and psychosis. In rodents and monkeys, MDMA is cytotoxic to serotonergic neurons, but this is less clear with humans. Herein, MDMA was cytotoxic to human serotonergic JAR cells; it altered ...
The recreational use of 3,4-methylenedioxymethamphetamine (MDMA) has increased as have the number of clinical reports linking MDMA use with cardiovascular toxicity. Nonetheless, the cardiovascular and sympathetic nerve responses elicited by MDMA have not been well characterized. The purpose of this study was to characterize the mean arterial pressure (MAP), heart rate (HR), and renal sympatheti...
3,4-Methylenedioxymethamphetamine (MDMA, "ecstasy") is increasingly used by young people for its euphoric and empathic effects. MDMA can be used in combination with other drugs such as selective serotonin reuptake inhibitors. A clinical trial was designed where subjects pretreated with paroxetine, one of the most potent inhibitors of both 5-hydroxytryptamine reuptake and CYP2D6 activity, were c...
