Restraint ulcer: history, current research and future implications

G B Glavin

    Brain Research Bulletin
    |January 1, 1980
    PubMed
    Summary

    The supine restraint-cold procedure effectively creates gastric ulcers in animals. This new model is responsive to treatments and influenced by emotionality, making it a valuable research tool for studying ulcers.

    Area of Science:

    • Gastroenterology
    • Pharmacology
    • Animal Models

    Background:

    • Gastric ulcers are a significant health concern.
    • Existing animal models for ulcer research have limitations.
    • A novel, reliable method for inducing gastric lesions is needed.

    Purpose of the Study:

    • To describe and validate a new ulcerogenic procedure: supine restraint-cold.
    • To assess the efficacy and reproducibility of this model in various animal species.
    • To investigate the influence of therapeutic agents and emotionality on induced gastric lesions.

    Main Methods:

    • Utilized a supine restraint-cold stress protocol in multiple animal species.
    • Administered known therapeutic agents (cimetidine, aluminum hydroxide) and autonomic drugs (scopolamine, carbachol).
    • Assessed gastric glandular lesions, including penetration of the muscularis mucosa (ulcers), and correlated with animal behavior.

    Main Results:

    • The supine restraint-cold procedure reliably induced a high incidence of gastric glandular lesions.
    • Lesions were responsive to cimetidine and aluminum hydroxide.
    • Autonomic drug administration and variations in animal emotionality significantly affected lesion development.

    Conclusions:

    • The supine restraint-cold procedure is a simple, effective, and reproducible method for creating gastric ulcers in experimental animals.
    • This model demonstrates responsiveness to therapeutic interventions and is influenced by behavioral factors.
    • The supine restraint-cold procedure represents a viable and useful research tool for ulcer studies.
