  • Title: Development of a circadian variation of plasma oxytocin concentration in the late gestation rhesus monkey.
    Author: Seron-Ferre M, Taylor NF, Martin MC, Leake RD.
    Journal: J Clin Endocrinol Metab; 1991 Jun; 72(6):1323-7. PubMed ID: 2026753.
    Abstract:
    The 24-h pattern of oxytocin (OT) concentrations in maternal plasma was investigated serially from 112-168 days gestation in four chair-restrained pregnant rhesus monkeys. No change in the mean daily plasma OT concentration was observed with advancing gestational age; there was a change in the pattern of plasma OT secretion throughout the period, however. About 21 days from delivery (150.8 +/- 1.8 days gestational age), plasma OT levels showed occasional fluctuations, distributed throughout the day. About 8 days from delivery (163.2 +/- 2.4 days gestational age), a clear circadian pattern of OT was detected, with an acrophase at 2200 h. These results suggest that there is a relationship between the pattern of OT secretion and advancing pregnancy. This may account partially for the increase in uterine activity known to occur in term rhesus monkeys.
