Abstract

In the presence of guanethidine, periarterial nerve stimulation caused a frequency-dependent motor response in the rabbit isolated ileum. Tachyphylaxis to capsaicin greatly diminished the effect of periarterial stimulation; the remaining portion of the contractile response was susceptible to hexamethonium. The motor effect of periarterial stimulation is mediated by two different mechanisms: one via parasympathetic preganglionic nerves and the other sensitive to capsaicin.

摘要

在胍乙啶存在的情况下,动脉周围神经刺激在兔离体回肠中引起频率依赖性运动反应。对辣椒素的快速耐受性大大降低了动脉周围刺激的效果;收缩反应的其余部分对六甲铵敏感。动脉周围刺激的运动效应由两种不同机制介导:一种通过副交感神经节前神经,另一种对辣椒素敏感。
