本文报道电刺激猫的自主神经时对鼻粘膜容量血管和阻力血管的影响。容量血管的变化以体积描记球测定,阻力血管的变化以颌内动脉终支的血流阻力变化代表。刺激颈交感神经干时鼻粘膜容积减少,颌内动脉阻力增加,提示颈交感神经支配鼻粘膜的容量血管和阻力血管使其收缩。刺激迷走神经干时容量血管和阻力血管均扩张。刺激翼管神经,当电压为0.2～0.8伏时,鼻粘膜容量血管、阻力血管均扩张,提示翼管神经中包含的副交感神经发挥了
This article reports the effects of electrical stimulation of cat’s autonomic nervous system on nasal mucosal and vascular resistance. Changes in volumetric vessels were measured by plethysmography, and changes in resistance vessels were represented by changes in blood flow resistance of the terminal branches of the internal mammary artery. Stimulation of cervical sympathetic trunk reduced nasal mucosa volume, increased resistance of the internal carotid artery, suggesting that the cervical sympathetic innervation of the nasal mucosa of blood vessels and resistance to blood vessels to shrink. Volumetric vessels and resistance vessels are dilated when vagus nerve is stimulated. Stimulation of the pterygoid nerve, when the voltage is 0.2 ~ 0.8 volts, the nasal mucosal volume of blood vessels, resistance blood vessels are dilated, suggesting that the parasympathetic nerve contained in the pterygoid nerve play
