Abstract

Haloperidol did not change significantly the rate of penetration of apomorphine to three investigated structures of the rat brain: striatum, limbic forebrain and cerebellum. It depressed, however, significantly the accumulation of apomorphine in the striatum and limbic forebrain; in the cerebellum, in which the accumulation of apomorphine was very low, haloperidol did not change it. In haloperidol-pretreated rats the pattern of elimination of apomorphine from the striatum changed, revealing the presence of two compartments; this was not observed in the limbic forebrain, from which the elimination was linear, both in the presence and absence of haloperidol.

摘要

氟哌啶醇对阿扑吗啡进入大鼠脑的三个研究结构(纹状体、边缘前脑和小脑)的渗透率没有显著影响。然而,它显著降低了阿扑吗啡在纹状体和边缘前脑中的蓄积;在小脑中,阿扑吗啡的蓄积非常低,氟哌啶醇对其没有影响。在经氟哌啶醇预处理的大鼠中,纹状体中阿扑吗啡的消除模式发生了变化,显示出存在两个区室;在边缘前脑中未观察到这种情况,无论有无氟哌啶醇,边缘前脑中阿扑吗啡的消除都是线性的。
