Results from this study2

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

Natural levels measured2

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.

  1. 01LabEndogenous levelEx vivo tissueMechanism

    In colchicine-treated male rats, a moderate number of oxytocin-stained cells in the paraventricular hypothalamus also stained positively for CRF.

    In plain wordsIn lab tests of hypothalamic tissue from male rats, the body's own oxytocin-stained cells also showed CRF staining.

    Summary
    In colchicine-treated male rats a moderate number of oxytocin-stained cells, localized primarily in a discrete, anterior part of the magnocellular division of the nucleus, was found also to stain positively for CRF.
