    In female rats with DMH-disturbed circadian rhythms, epitalon was more effective in the median eminence with arcuate nuclei and prevented the xenobiotic-caused disturbance of the diurnal dopamine rhythm.

    In plain wordsIn female rats with disturbed body rhythms, epitalon prevented the disturbance of the daily dopamine pattern in one brain area.

    Summary
    Epitalon (Ala-Glu-Asp-Gly) proved to be more effective in ME-Arc. This peptide prevents the xenobiotic caused disturbance of DA diurnal rhythm, keeping this metabolite low at 5 o'clock (CT) with it having increased by 11 o'clock (CT).

Studies that did not test the peptide alone1

In this study, Epitalon 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 Epitalon.

    In female rats with DMH-disturbed circadian rhythms, melatonin and the pineal peptides epithalamine and epitalon exerted a correcting influence on the diurnal dynamics of norepinephrine in the medial preoptic area; effects were not reported separately.

    In plain wordsIn female rats with disturbed body rhythms, epitalon with other pineal substances corrected the daily pattern of norepinephrine in one brain area.

    Summary
    We have shown that melatonin and the pineal gland peptides (epithalamine and epitalon) exert a correcting influence on the diurnal dynamics of norepinephrine (NE) in the medial preoptic area (MPA) and of dopamine (DA) in the median eminence with arcuate nuclei (ME-Arc) disturbed by single administra…

    In this study, Epitalon 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 Epitalon.
