  • Title: Effects of parasympathectomy on protein composition of sympathetically evoked parotid saliva in rats.
    Author: Proctor GB, Asking B, Garrett JR.
    Journal: Comp Biochem Physiol A Comp Physiol; 1990; 97(3):335-9. PubMed ID: 1979532.
    Abstract:
    1. Male Wistar rats were given unilateral postganglionic parasympathectomies by sectioning the auriculo-temporal nerve. 2. Analyses of the protein compositions of sympathetically induced saliva from both glands 1 week later revealed changes in the proportions of different secretory proteins, in particular amylase and basic proline-rich proteins were decreased. 3. These results suggest that parasympathetic impulses are required for the normal synthesis of amylase by parotid parenchyma in rats. Basic proline-rich proteins, known to require a sympathetic drive for normal synthesis, appear to require a parasympathetic input as well.
