    Journal: Nihon Jibiinkoka Gakkai Kaiho; 1990 Apr; 93(4):583-9. PubMed ID: 2376794.
    Abstract:
    In the present study reflex manners in capacitance and resistance vessels of the nasal mucosa have been observed respectively and simultaneously by stimulating the a) Cervical sympathetic nerve trunk, b) Vagal nerve, c) Vidian nerve, d) sympathectomized Vidian nerve electrically. Capacitance change in the nasal mucosa was measured by plethysmographic balloons inserted into the nasal cavity. Resistance change was measured as the pressure change in the terminal branch of the maxillary artery by using the constant flow perfusion method. a) Stimulation of the cervical sympathetic nerve trunk evoked a decrease change in the volume of the nasal mucosa and an increase change in the resistance of the maxillary artery. b) Stimulation of the Vagal nerve evoked an increase change in the volume of the nasal mucosa and a decrease change in the resistance of the maxillary artery. c) Stimulation of the Vidian nerve there were observed an increase change in the volume of the nasal mucosa and a decrease change in the resistance of the maxillary artery at the low stimulation intensity, from 0.2 to 0.8 volts. Further increasing the stimulation intensity, from 1.0 to 6.0 volts a decrease change in the volume of the nasal mucosa was observed. In spite of the reverse change in the capacitance vessel, pressure in the maxillary artery still maintained low pressure level. d) Stimulation of the sympathectomized Vidian nerve evoked an increase change in the volume of the nasal mucosa and a decrease change in the maxillary artery. Manner of these reflex was very similar to that of the Vagal nerve stimulation.(ABSTRACT TRUNCATED AT 250 WORDS)
