[Stress and the salivary glands].

Abstract

The object of this work was to establish whether induced stress leads to morphological changes in the sublingual and submaxillary glands of rats. General adaptation syndrome (S.G.A.) was induced in 25 young adult male Wistar rats through cold and immobilization. The animals were killed 48 hrs. and 10 days after stressor (E.A.) application. To verify stress condition, the adrenales were weighed and plasmatic corticosterone were carried out. The sublingual and submaxillary glands were dissected, fixed in buffered formol and stained with H.E. The results histology indicate that the submaxillary is more sensitive to cold than the sublingual, while the reverse holds true form immobilization.
