Results from this study2

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.

  1. 01AnimalEndogenous levelAnimal study (in vivo)Other

    In anesthetized rats, electrical stimulation of the gastric vagal nerves increased plasma levels of the body's own oxytocin.

    In plain wordsIn rats, stimulating the stomach nerves raised the body's own oxytocin levels in blood.

    Summary
    Electrical stimulation of the gastric vagal nerves increased the plasma levels of OXT, but not AVP.

    Summary · context
    Effects of electrical stimulation of the gastric vagal nerves on plasma levels of oxytocin (OXT) and arginine vasopressin (AVP) were examined in rats anesthetized with urethane.

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

Studies that did not test the peptide alone1

In this study, Oxytocin was a lab tool or a carrier, part of a mix, or the subject of a lab method. These results are not evidence about taking Oxytocin.

  1. 02AnimalNot a test of Oxytocin aloneAnimal study (in vivo)Mechanism

    In anesthetized rats, most recorded putative oxytocin-secreting paraventricular neurons were excited by gastric vagal nerve stimulation and by intravenous CCK-8.

    In plain wordsIn rats, most recorded oxytocin-producing brain cells became more active when stomach nerves were stimulated or CCK-8 was given.

    Summary
    Most of the putative OXT-secreting cells recorded were excited by both electrical stimulation of gastric vagal nerves and i.v. administration of CCK-8.
