Effects of lung inflation on nasal airway resistance in the anesthetized rat

M. A. Lung
Department of Physiology, Faculty of Medicine, University of Hong Kong.

Nasal airway resistance was assessed in halothane-anesthetized rats by measuring the transnasal pressure at constant airflow through both nasal cavities. Low inflation pressures (2.5-5 cmH2O) decreased nasal airway resistance, whereas higher inflation pressures (10-20 cmH2O) caused a biphasic response: an initial increase in resistance followed by a decrease in resistance. The nasal responses to all levels of inflation were completely abolished by hexamethonium, guanethidine, or bretylium pretreatment or cervical sympathectomy and greatly lessened by cervical vagotomy or phenoxybenzamine pretreatment. Atropine and propranolol pretreatments had no effect on the responses. These findings indicate that the nasal airway resistance is related to the level of inflation through pulmonary reflexes with afferents along the vagi and efferents via the alpha-adrenergic nervous system.
