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 rats bred for high anxiety, the body's own oxytocin mRNA expression in the paraventricular nucleus did not differ from that in rats bred for low anxiety.

    In plain wordsIn rats bred for high anxiety, the body's own oxytocin gene activity in one brain area was not higher than in low-anxiety rats.

    Summary
    AVP, but not OXT, mRNA expression as well as release of the neuropeptide, were higher in the PVN of HABs
    2 context sentences
    Summary · context
    To model aspects of trait anxiety/depression, Wistar rats were bred for extremes in either hyper (HAB)- or hypo(LAB)-anxiety as measured on the elevated plus-maze and in a variety of additional behavioral tests.
    Summary · context
    Thus, CRH, arginine-8-vasopressin (AVP), and oxytocin (OXT) were studied in brains of HAB and LAB males both under basal conditions and after exposure to a mild emotional stressor.

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