Cocaine treatment (10 or 50 mg/kg, i.m.): 1) did not change significantly the amount of 3H dopamine synthesized from 3H tyrosine in the striatum but reduced the specific activity of 3H tyrosine; 2) delayed the release of cerebral dopamine after inhibition of its biosynthesis by alpha-methylparatyrosine; 3) reduced the amount of 5-hydroxyindolacetic acid accumulated after Probenecid, which reflects an inhibitory effect on serotonin release; 4) did not change significantly the acetylcholine level of the brain.
可卡因治疗(10或50毫克/千克,肌肉注射):1)纹状体中由3H酪氨酸合成的3H多巴胺量无显著变化,但3H酪氨酸的比活性降低;2)在α-甲基对酪氨酸抑制其生物合成后,延迟了脑多巴胺的释放;3)降低了丙磺舒后积累的5-羟吲哚乙酸量,这反映了对血清素释放的抑制作用;4)脑中乙酰胆碱水平无显著变化。
