理论基础:5-羟色胺功能降低已被证明可以诱导与“抗焦虑”效果一致的行为。给大鼠单次注射3,4-亚甲基二氧基甲基苯丙胺(MDMA;“摇头丸”12.5 mg/kg ip)可延长中枢5-羟色胺能神经末梢的损伤。因此,我们希望评估MDMA诱导的损伤是否会有更长期的行为后果。目的:本研究旨在观察单次神经毒性剂量(12.5 mg/kg ip)MDMA处理的动物和对照组动物在高架迷宫和开阔场地中的行为。结果:在给药后第73天(空旷场)和第80天(加迷宫),经MDMA处理的Dark Agti大鼠在高架正迷宫和开阔场地的焦虑相关行为均显著低于生理盐水对照组大鼠。结论:单次神经毒性剂量的MDMA可在给药2个月后表现出行为后果,从而表明在这种再利用药物产生的5-羟色胺神经元变性后,大脑内发生了长期的适应性变化。
Rationale: Decreased 5-HT function has been shown to induce behaviour consistent with an "anxiolytic" effect. Administration of a single dose of 3,4-methylenedioxymethamphetamine (MDMA; "ecstasy" 12.5 mg/kg IP) to rats results in prolonged damage to central serotonergic nerve terminals. Thus we wished to assess whether an MDMA-induced lesion may have longer-term behavioural consequences. Objective: The study was designed to examine the behaviour of MDMA-pretreated and control animals in the elevated plus-maze and open field at a number of time-points, up to 80 days, after the administration of a single neurotoxic dose of MDMA (12.5 mg/kg IP). Results: MDMA-pretreated Dark Agouti rats demonstrated a statistically significant reduction in anxiety-related behaviour, compared to saline-pretreated control rats, in both the elevated plus-maze and open field when the rats were tested on day 73 (open field) and day 80 (plus maze) after MDMA administration. Conclusions: The behavioural consequences of a single neurotoxic dose of MDMA can be demonstrated over 2 months after administration of the compound, thereby indicating that long-term adaptive changes occur within the brain following the neurodegeneration of 5-HT neurones produced by this recreationally used drug.
