title: Non-adrenergic, non-cholinergic reflex secretion of parotid saliva in rats elicited by mastication and acid applied on the tongue.
abstract: Chewing and acid on the tongue evoked a flow of saliva from the duct-cannulated parotid gland of the conscious rat despite pretreatment with atropine and adrenoceptor antagonists. This non-adrenergic, non-cholinergic (NANC) response depended on an intact parasympathetic innervation and was abolished by a tachykinin antagonist. The present findings are consistent with a physiological role for the secretory NANC mechanisms of the salivary glands.
