The cough reflex in anaesthetized rabbits was elicited by irritation of the larynx with ammonia, inhalation ammonia into lungs, and mechanical stimulation tracheobronchial tree a catheter. After block lung stretch receptors sulphur dioxide virtual abolition Breuer-Hering inflation reflex, response to all three stimuli far less frequent and, when it occurred, weaker especially respect expiratory efforts. It is concluded that enhances although modification sensitivity irritant may also influence cough.
