The binding of [3H]3,4-methylenedioxymethamphetamine [( 3H]MDMA) to both rat brain membrane preparations and glass fiber filter papers was analyzed in the present study. Saturation studies indicate that [3H]MDMA binding is saturable and monophasic in both the presence and absence of rat brain membranes. This apparent 'specific' binding of [3H]MDMA in both the presence and absence of brain homog...

Hyponatremia is a serious complication of 3,4-methylenedioxymethamphetamine (MDMA) use. We investigated potential mechanisms in two double-blind, placebo-controlled studies. In Study 1, healthy drug-experienced volunteers received MDMA or placebo alone and in combination with the alpha-1 adrenergic inverse agonist prazosin, used as a positive control to release antidiuretic hormone (ADH). In St...

BACKGROUND AND PURPOSE The use of ± 3,4-methylenedioxymethamphetamine (MDMA, 'ecstasy') is associated with cardiovascular complications and hyperthermia. EXPERIMENTAL APPROACH We assessed the effects of the α(1) - and β-adrenoceptor antagonist carvedilol on the cardiostimulant, thermogenic and subjective responses to MDMA in 16 healthy subjects. Carvedilol (50 mg) or placebo was administered ...

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...

Objective(s): 3,4-Methylenedioxymethamphetamine (MDMA) is one of the most popular drugs of abuse in the world with hallucinogenic properties that has been shown to induce apoptosis in  liver cells. The present study aimed to investigate the effects of pentoxifylline (PTX) on liver damage induced by acute administration of MDMA in Wistar rat. Materials and Methods: Animals were administered wit...

introduction: 3-4, methylenedioxymethamphetamine (mdma) causes apoptosis in nervous system and several studies suggest that oxidative stress contributes to mdma-induced neurotoxicity. the aim of this study is to examine the effects of n-acetyl-l-cystein (nac) as an antioxidant on mdma-induced apoptosis. methods: 21 sprague dawley male rats (200-250mg) were treated with mdma (2×0,5mg/kg) or mdma...

  Background :Adenosine is an endogenous purine nucleoside that has a neuromodulatory role in the central nervous system. The amphetamine derivative (±)-3,4-methylenedioxymethamphetamine (MDMA or ecstasy) is a synthetic amphetamine analogue used recreationally to obtain an enhanced affiliated emotional response. MDMA is a potent monoaminergic neurotoxin with the potential of damage to brain neu...

3, 4 Methylenedioxymethamphetamine (MDMA) also known as Ecstasy is a common recreational drug of abuse and reports of abuse of tricyclic antidepressants are also known. We report two cases of misuse of selective serotonin re-uptake inhibitors (SSRIs) antidepressants in combination with Ecstasy and their beneficial subjective effects experienced by misusers. We hypothesise the probable underlyin...

The effects of 3,4-methylenedioxymethamphetamine (MDMA) on monoamine release were investigated in superfused slices of rat striatum and hippocampus. MDMA (10 microM) increased the resting release of radioactivity from slices incubated in [3H]dopamine, [3H]5-hydroxytryptamine or [3H]noradrenaline. These effects of MDMA (10 microM) were blocked by the neuronal uptake inhibitors, cocaine (10 micro...
