Abstract
  1. A study has been made in the anaesthetized cat of the stimulation parameters required to separate the vasodilator and vasoconstrictor responses evoked in the nose by stimulating the cut peripheral end of the Vidian nerve.2. The extent of the vasodilation and vasoconstriction was found to be dependent on the stimulation frequency, but whereas vasodilation reached a maximum at 25 Hz, vasoconstriction occurred at lower frequencies and was maximum between 10 and 15 Hz.3. Atropine, in a dose much greater than that which inhibits nasal secretion, did not abolish the vasodilator responses evoked by Vidian nerve stimulation. This suggests that the Vidian nerve may convey atropine resistant fibres to the nasal vasculature.
摘要
  1. 对麻醉猫进行了一项研究,以确定刺激翼管神经切断的外周端在鼻内引发血管舒张和血管收缩反应所需的刺激参数。

  2. 发现血管舒张和收缩的程度取决于刺激频率,但血管舒张在25Hz时达到最大值,而血管收缩在较低频率时出现,在10至15Hz之间达到最大值。

  3. 阿托品的剂量远大于抑制鼻部分泌所需的剂量,但并未消除翼管神经刺激引起的血管舒张反应。这表明翼管神经可能向鼻血管输送抗阿托品纤维。
