VIP-containing nerve fibres in the submandibular gland of the dog and protein secretion in vitro in response to VIP.
Previously, administration of VIP has been shown to elicit no flow of saliva from the submandibular gland of the dog. However, in the present study we found VIP to cause release of protein in vitro from canine submandibular gland tissue. Furthermore, VIP-containing nerve fibres were demonstrated in large numbers in association with acini. Thus, VIP may be involved in the nervous regulation of salivary protein secretion in the dog.
