Pancreatic ectasia in uremic macaques.

R T Bronson, W Strauss, W Wheeler

    The American Journal of Pathology
    |March 1, 1982
    PubMed
    Summary

    Pancreatic ectasia, a condition involving pancreatic duct dilation, was studied in uremic macaques. Researchers found atrophic acinar cells and fibrillar material, but no ductal proliferation or blockage.

    Area of Science:

    • Veterinary Pathology
    • Gastroenterology
    • Comparative Pathology

    Background:

    • Pancreatic ectasia (PE) is frequently observed in individuals with uremia.
    • Previous descriptions noted acinar dilatation, secretion inspissation, and ductal cell proliferation.

    Purpose of the Study:

    • To investigate the pathological features of pancreatic ectasia in uremic macaques.
    • To characterize the cellular and structural changes associated with PE.

    Main Methods:

    • Light and electron microscopy
    • Histochemistry
    • Three-dimensional modeling from serial sections

    Main Results:

    • PE observed in 17 macaques, 11 with known uremia.
    • Atrophic acinar cells and centroacinar cell clumps lined the dilated system.
    • Fibrillar material present in lumens; no ductular proliferation or blockage confirmed.

    Conclusions:

    • The observed pancreatic ectasia in uremic macaques shares similarities with experimental lesions and cystic fibrosis pathology.
    • Findings suggest a distinct pathological process rather than simple ductal proliferation.
