Results from this study1

No result from this study comes from a test of the peptide.

Natural levels measured1

These results measure the body's own peptide. Nobody was given the peptide. They are not evidence about taking it. They are left out of key results, evidence counts and charts.

    In Sprague-Dawley rats, natural VIP immunoreactivity was increased in the lower functional gut after jejuno-ileal bypass.

    In plain wordsIn rats, the body's own VIP was higher in the lower working gut after a bypass operation.

    Summary · context
    In this study with Sprague-Dawley rats, glucagon, secretin and vasoactive intestinal polypeptide (VIP), immunoreactivities were measured in extracts of gut tissues including formerly adjacent segments of functional and bypassed jejunum and ileum. Young adult (200-220 g) and mature (404-440 g) rats r…
