Results from this study4

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

Natural levels measured4

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)Mechanism

    In rats, intracerebroventricular hANP (50 nmol) inhibited oxytocin release following dehydration.

    In plain wordsIn rats, hANP given into the brain lowered release of the body's own oxytocin after dehydration.

    Summary
    Intracerebroventricular hANP (50 nmol) inhibits release of vasopressin and oxytocin following dehydration as well as after haemorrhage.

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

  3. 03LabEndogenous levelEx vivo tissueMechanism

    In rat neurointermediate lobes in vitro, 10 nmol/L hANP markedly inhibited basal oxytocin release.

    In plain wordsIn rat pituitary tissue in the lab, hANP strongly lowered release of the body's own oxytocin at rest.

    Summary
    10 nmol/L hANP markedly inhibits vasopressin and oxytocin release in vitro from the neurointermediate lobes both under basal condition as well as during stimulation with excess (56 mM) potassium.

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