Hyperthermia and hyperlocomotor activity are commonly reported acute effects of high dose, experimenter-delivered 3,4-methylenedioxymethamphetamine (MDMA). The current investigation was performed to determine short- to long-term physiological and behavioral changes induced by moderate intake MDMA self-administration. In the present study, rats self-administered MDMA (approx. 2.0-7.0 mg/kg/day)...
In the present study the effects of a neurotoxic regimen of (+)-MDMA (20 mg/kgx4, s.c.) in 4- and 10-week-old C57Bl/6J mice during treatment and 7 days post-treatment were examined. Rectal temperatures monitored between (+)-MDMA injections (30 min post-injection/2 h intervals) revealed hyperthermic responses in both age groups, with the magnitude of the response significantly greater in older...
