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)Efficacy outcome

    In mice, oxytocin gene deletion significantly increased saccharin solution intake in the dark and light photoperiods compared with wild type, and the result was replicated.

    In plain wordsIn mice that lack the oxytocin gene, intake of a sweetener solution was higher than in normal mice, day and night.

    Summary
    Compared to WT mice, OT KO mice consumed significantly greater volumes of saccharin solution during the dark and light photoperiods on the first day and subsequent days of the study. The results were replicated when the experiment was repeated in the same animals.

    Summary · context
    In this study we examined the ingestion of a non-nutritive sweetener, 0.2% saccharin in sucrose-experienced OT KO and WT mice given a two-bottle choice between saccharin solution and water available ad libitum for 4 days.

    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.

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

    In mice, oxytocin knockout mice drank significantly more sucrose than wild-type mice during periods of stress and non-stress.

    In plain wordsIn mice that lack the oxytocin gene, sugar solution intake was higher than in normal mice, with or without stress.

    In oxytocin knockout mice, daily platform shaker stress did not alter the marked sucrose consumption.

    In plain wordsIn mice that lack the oxytocin gene, daily shaking stress did not change their high sugar solution intake.
