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. 01AnimalEndogenous levelAnimal study (in vivo)Other

    Pigtail macaques had significantly lower CSF oxytocin concentrations than bonnet macaques.

    In plain wordsIn macaques, the more volatile pigtail species had lower levels of the body's own oxytocin in spinal fluid than the bonnet species.

    Summary · context
    Cisternal CSF samples were obtained from young adult male and female pigtail and bonnet macaques, and CRF and OT concentrations were measured by radioimmunoassay.

    This result measures the body's own Oxytocin. Nobody was given the peptide. It is not evidence about taking it.

  2. 02AnimalEndogenous levelAnimal study (in vivo)Other

    In multiple regression, CSF CRF and oxytocin together gave a multiple R of 0.76 and accounted for more than half of the species variance.

    In plain wordsIn macaques, spinal fluid levels of CRF and the body's own oxytocin together explained more than half of the difference between species.
