Results from this study3

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

Studies that did not test the peptide alone3

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. 01AnimalNot a test of Oxytocin aloneAnimal study (in vivo)Mechanism

    In rats, estrogen administration induced expression of oxytocin binding sites in the major island of Calleja, anterior hypothalamic area and terete nucleus.

    In plain wordsIn rats, estrogen increased the number of oxytocin binding sites in several brain areas.

    Summary · context
    The localization at the cellular level and the regulation by progesterone of the estrogen-sensitive oxytocin binding sites was studied in the rat telencephalon and the hypothalamus by using quantitative film-autoradiography and histoautoradiography.
    Summary · context
    Male rats (castrated or not) and ovariectomized females (estradiol supplemented or not) were used to characterize these sites and to precise their localization.

  2. 02AnimalNot a test of Oxytocin aloneAnimal study (in vivo)Mechanism

    In rats, the density of estrogen-sensitive oxytocin binding sites varied during the estrous cycle, and the pattern differed between the telencephalon and the hypothalamus.

    In plain wordsIn rats, the number of oxytocin binding sites changed during the estrous cycle, with different patterns in two brain regions.

    Summary
    They were detected in the striatal cell bridges, the olfactory tubercle, the principal nucleus of the bed nucleus of the stria terminalis and the medial nucleus of the amygdala of the telencephalon and in the medial preoptic, the ventromedial and the ventral premammillary nuclei of the hypothalamus.

    In this study, Oxytocin was a lab tool or a carrier, part of a mix, or the subject of a lab method. This result is not evidence about taking Oxytocin.
