Abstract:
:A novel peptide, submandibular gland peptide-T (SGP-T), which reduces allergen-induced hypotension, was examined for effects on intestinal anaphylaxis. Hooded-Lister rats were sensitized to egg albumin and prepared for the measurement of in vivo myoelectric activity of the jejunum. The disruption of migrating myoelectric complexes (MMCs) that occurs upon intraluminal, duodenal challenge with antigen of sensitized rats was inhibited by 75% upon intravenous treatment with 100 micrograms/kg of SGP-T. In addition, SGP-T reduced the number of rats experiencing anaphylactic diarrhea and disrupted MMCs, but the peptide did not alter antigen-provoked release of rat mast cell protease II. The mechanism of action of SGP-T remains to be determined, but it apparently does not act directly on mast cells to exert its antianaphylactic action. These results emphasize that modulation of immediate hypersensitivity reactions is only one of several gastrointestinal activities that are affected by growth factors and peptides released from salivary glands.
