Human airways, from the middle of the trachea to the distal bronchi, were studied in vitro for the presence of inhibitory nerves. The tissue was obtained from operations and from recent autopsies. Electrical field stimulation of the tissues demonstrated cholinergic, excitatory nerves and their effect was blocked by atropine. Field stimulation of the tissues, in the presence of atropine, relaxed the smooth muscle even when the muscle was contracted by histamine. The field stimulation-induced relaxation was neither blocked nor modified by adrenergic blocking agents. Maximum relaxation of the bronchial muscle was obtained with a pulse duration of 1–2 ms, 70 V,and frequencies of 20 Hz and greater. The tracheal smooth muscle showed 85%of maximal relaxation with a frequency of 10 Hz. Tetrodotoxin, blocked the field stimulation-induced relaxation for pulse durations of 2 ms; this indicated that nerves were being stimulated. The airway system shows some of the characteristics of the nonadrenergic inhibitory system in the gastrointestinal tract and of the system reported in the guinea pig trachealis muscle.No evidence of adrenergic inhibitory fibers was found in the bronchial muscle with either pharmacological or histochemical techniques. These findings suggest that the nonadrenergic inhibitory system is the principal inhibitory system for the smooth muscle of human airways. We suggest that a defect in the airway system, such as that shown in the gastrointestinal tract, may be an explanation for the hyperreactive airways of asthma and chronic bronchitis.

Strips of smooth muscle, cut transversely from the smooth-muscle segment of opossum esophagus, were superfused with oxygenated Krebs-Ringer solution at 37 degrees C in a system that allowed electrical field stimulation of the intrinsic nerves. Three-to-five-second trains of rectangular pulses (0.5 ms long at 10 Hz) were delivered at 30-s intervals at supramaximal maximal current strength. In strips from the esophageal body, each train resulted in a twitch which followed after the end of train with a particular latency, the off-response. Strips from the esophagogastric sphincter relaxed during the train. Temperature was varied above and below 37 degrees C to observe the temperature dependence of the responses. Latency of the off-response varied exponentially with temperature. Amplitude of the off-response showed a linear decline with changes in temperature, both above and below 35 degrees C, the zero-intercepts being 19.6 and 42.3 degrees C, respectively. Amplitude of relaxation of strips from the junction varied little between 20 and 37 degree C but declined sharply beyond those limits, the zero-intercepts being 14.2 and 42 degrees C, respectively.
