Data are mean ±S.E.M. and parentheses indicate numbers of animals in the group. Drug injection for intervention at specific receptor sites took place 30 min before MDMA administration. Drug dosages were expressed as mg/kg indicated in the second column. Dosage of MDMA was 3 mg/kg followed by 30-min physical activity on a treadmill at warm temperature of 32 °C.
