Glucagon and small-bowel mucosa.

E O Riecken, M Gregor

    Scandinavian Journal of Gastroenterology. Supplement
    |January 1, 1985
    PubMed
    Summary

    Glucagon impacts the small intestine, but its physiological role is unclear. Enteroglucagon, a related peptide, may influence intestinal growth in various diseases.

    Area of Science:

    • Gastroenterology
    • Endocrinology
    • Cell Biology

    Background:

    • Pharmacological doses of glucagon affect small-intestinal mucosa.
    • Elevated plasma glucagon levels correlate with intestinal mucosal alterations in certain conditions.
    • The precise physiological and pathophysiological significance remains debated due to complex findings and methodologies.

    Purpose of the Study:

    • To investigate the role of enteroglucagon in intestinal mucosal growth.
    • To explore the relationship between enteroglucagon and various disease states affecting the small intestine.
    • To discuss the potential of monoclonal antibodies for studying glucagon and enteroglucagon deficiency.

    Main Methods:

    • Analysis of enteroglucagon levels in relation to radiation damage.
    • Monitoring plasma enteroglucagon during antimitotic treatment.
    • Assessment of enteroglucagon in small intestinal resection and blind loop syndrome models.

    Main Results:

    • Enteroglucagon is particularly important for potential trophic effects on the small bowel mucosa.
    • Elevated enteroglucagon levels are observed in diseases characterized by increased intestinal mucosal growth.
    • Specific disease models (radiation, antimitotic treatment, resection, blind loop) were examined for enteroglucagon dynamics.

    Conclusions:

    • Enteroglucagon is a key peptide potentially involved in regulating small intestinal mucosal growth.
    • Further research using monoclonal antibodies could elucidate the physiological importance of glucagon and enteroglucagon.
