Several mechanisms underlying 3,4-Methylenedioxy-N-methylamphetamine (MDMA) neurotoxicity have been proposed, including neurochemical alterations and excitotoxicity mediated by reactive oxygen species (ROS), nitric oxide (NO), and reactive nitrogen species (RNS). However, ROS, NO, and RNS sources in the brain are not fully known. We aimed to investigate possible alterations in the expression of...

Indirect effects of 3,4-methylenedioxy-N-methylamphetamine (MDMA) and metabolites on the cardiac cells are well-known, the mechanism(s) underlying direct MDMA-induced cardiotoxicity remaining to be clarified. To better understand the immuno-inflammatory phenomena accompanying the cardiac alterations during MDMA administration, we conducted a study in an in vivo animal model to evaluate the...

Studies conducted in humans or in animals explored the presence, nature and potential causes of 3,4-methylenedioxymethamphetamine (MDMA) toxicity. According to literature, there are four principal types of such serious toxicity: hepatic, cardiovascular, cerebral and hyperpyrexic. The molecular mechanisms involved in the genesis of these toxic effects are not yet fully clarified, but the...

Abstract 3,4‐Methylenedioxymethamphetamine (MDMA)‐induced neurotoxicity leads to the formation of quinone metabolities and hydroxyl radicals and then to the production of reactive oxygen species (ROS). We evaluated the effect of a single dose of MDMA (20 mg/kg, i.p.) on the enzymatic and nonenzymatic cellular antioxidant defense system in different areas of rat brain in the early hours (<6 hr)...

Experimental and clinical data indicate that 3,4-methylenedioxy-N-methylamphetamine (MDMA) abuse can produce significant cardiovascular toxicity. A mechanism may be a direct toxic effect of redox active metabolites of MDMA. To evaluate the effect of a single MDMA dose on cellular antioxidant defence system and to investigate the morphology in male albino rats, total glutathione (GSH), oxidised...

Three fatal cases of MDMA/MDEA misuse have been examined. These referred to white males between 19 and 20 years of age, in which post-mortem toxicology showed the presence of MDMA (in one case), MDEA (in one case) and both (in one case). The clinical data were analysed and the histopathological findings were studied following immunohistochemical investigations. A complete immunohistochemical...
