title: Parasympathetic NANC-secretion of saliva in the mink, and effects of substance P and VIP.
abstract: In both parotid and submandibular glands a parasympathetic non-adrenergic, non-cholinergic (NANC) nerve-evoked secretion of saliva was demonstrated. Saliva evoked by exogenous substance P was poor in protein, while saliva evoked by VIP was protein-rich. In a subthreshold dose for fluid secretion VIP released protein and potentiated the responses elicited by substance P, particularly regarding the output of protein. The two neuropeptides may contribute to the parasympathetic NANC secretion of saliva in the mink. Further, agonists responsible for the secretory NANC response are also likely to contribute to the secretory response of the glands to parasympathetic stimulation in the absence of autonomic receptor blockade in this species.
