Extracellular levels of serotonin (5-HT) and 5-hydroxyindolacetic acid (5-HIAA) were measured in the medial pontine reticular formation of acute decerebrate cats. The mean basal levels of 5-HT and 5-HIAA were 26 fmol/20 microliters and 15 pmol/20 microliters. Perfusion of the dialysis probe with high K+ and Ca(2+)-free Ringer solution for 60 min resulted in 4.8-8.5 x increase and 25-48% decrease in the extracellular levels of 5-HT, respectively, in comparison to the basal 5-HT levels. Perfusion with TTX-added Ringer solution for 60 min resulted in a consistent decrease in the extracellular levels of 5-HT.
在急性去脑猫的脑桥内侧网状结构中测量了血清素(5-羟色胺,5-HT)和5-羟吲哚乙酸(5-HIAA)的细胞外水平。5-HT和5-HIAA的平均基础水平分别为26飞摩尔/20微升和15皮摩尔/20微升。与基础5-HT水平相比,用高钾和无钙林格液灌注透析探头60分钟,导致5-HT的细胞外水平分别增加4.8 - 8.5倍和降低25 - 48%。用添加了河豚毒素的林格液灌注60分钟导致5-HT的细胞外水平持续下降。
