  • Title: Effect of bile on lysosomal stability in the mucosa of the canine gastric antrum.
    Author: Waldron-Edward D, Boutros MI, Himal HS.
    Journal: Gastroenterology; 1977 Nov; 73(5):980-4. PubMed ID: 908509.
    Abstract:
    The bound and free acid hydrolases from bile and bile- then acid-treated canine antral mucosa were compared with control tissue, using explants held in a series of Lucite chambers. Normal levels of activity of bound mucosal enzymes decreased as a result of bile acid insult, but "free" activity in the cytosol increased markedly. Organelle membrane stability was "tested" by submitting isolated particulate matter containing lysosomes, to hypoosmotic shock and to mechanical stress. Release of cathepsin D, only, was observed after bile treatment in vivo. Bile, followed by acid, however, damaged organelle integrity causing release or "leakage" of seven acid hydrolases.
