  • Title: Mechanisms of increase in amylase activity in rat submandibular and sublingual glands after administration of pilocarpine.
    Author: Ikeno T, Nasu J, Hashimoto S, Kuzuya H.
    Journal: Arch Oral Biol; 1982; 27(7):597-601. PubMed ID: 6181770.
    Abstract:
    The increase in parotid rather than pancreatic-type amylase activity in the submandibular and sublingual glands of rats caused by administration of pilocarpine was abolished or diminished when pilocarpine was injected into rats which had been parotidectomized, sympathectomized by superior cervical ganglionectomy or pretreated with reserpine. These results suggest that the increases in amylase activity in the submandibular and sublingual glands by pilocarpine are not due to increase in enzyme synthesis, but to uptake of enzyme released into the blood in large quantities from the parotid gland and that the release from the parotid gland by pilocarpine is primarily mediated by sympathetic nerves.
