在清醒、自由活动的大鼠体内微透析测量中,全身给药安非他明类似物3,4 -亚甲基二氧基甲基苯丙胺(MDMA)产生纹状体细胞外多巴胺(DA)浓度的剂量依赖性增加。在给予MDMA(10和20 mg/kg, ip)后,透析液样品中DA代谢物3,4 -二羟基苯基乙酸(DOPAC)的细胞外浓度显著降低。5-羟色胺-2 (5-HT 2)拮抗剂酮色林(3mg /kg, ip)对大鼠纹状体细胞外DA和DOPAC浓度无影响。在MDMA (20 mg/kg)前1小时给予酮色林(3 mg/kg)可显著减弱MDMA诱导的DA细胞外浓度升高,而不影响DOPAC浓度的降低。这些数据提示MDMA增加了清醒、自由活动的大鼠纹状体中DA的释放。此外,mdma诱导纹状体中DA细胞外浓度的增加部分是通过5-HT 2受体机制介导的。
Systemic administration of the amphetamine analogue, 3, 4-methylenedioxymethamphetamine (MDMA) produced a dose-dependent increase in the extracellular concentration of dopamine (DA) in the striatum as measured by in vivo microdialysis in awake, freely-moving rats. The extracellular concentration of the DA metabolite, 3, 4-dihydroxyphenylacetic acid (DOPAC), was significantly decreased in dialysate samples following the administration of MDMA (10 and 20 mg/kg, ip). The serotonin-2 (5-HT 2) antagonist ketanserin (3 mg/kg, ip) had no effect on the extracellular concentration of DA or DOPAC in the striatum of vehicle-treated rats. The administration of ketanserin (3 mg/kg) 1 hr prior to MDMA (20 mg/kg) significantly attenuated the MDMA-induced increase in the extracellular concentration of DA without affecting the decrease in DOPAC concentrations. These data are suggestive that MDMA administration increases DA release in the striatum of awake, freely-moving rats. In addition, MDMA-induced increase in the extracellular concentration of DA in the striatum is mediated, in part, via 5-HT 2 receptor mechanisms.
