...S. Deloof; A. Chatelain; A. Leprêtre The effects of rat corticotropin-releasing factor (rCRF, 1.25 pmol/50 μl/fetus), arginine vasopressin (AVP, 5 pmol/50 μl/fetus) and oxytocin (OT, 12.5 pmol/50 μl/fetus) alone or in association were investigated in 21-day-old rat fetuses injected intravenously...

...Gore Ervin; Janet A. Amico; Rosemary D. Leake; Michael G. Ross; Alan G. Robinson; Delbert A. Fisher Plasma of human adults contains an oxytocin, vasotocin-like (OT-VT) immunoreactive material that is estrogen responsive in both males and females and the levels of which are elevated during pregnancy...

...M. Hollingsworth; E.A. Oyewo Serum bilirubin concentrations were investigated in neonatal rats. High concentrations were found on day 1 falling to adult values by day 4. Oxytocin (500 IU/kg) given subcutaneously to the dams on day 22 of pregnancy increased bilirubin concentrations in neonatal rats...

...Alice C. Yao; Arne Nergårdh; Lars Boréus The influence of oxytocin and meperidine on responses of the isolated umbilical artery to acetylcholine (ACh) and/or 5-hydroxytryptamine (5-HT) was investigated. 32 preparations from 21 normal full-term deliveries were utilized. The Bunce double-blade...

...Rosemary D. Leake; Richard E. Weitzman; Delbert A. Fisher Plasma oxytocin levels in the umbilical artery (UA) exceeded umbilical venous levels in newborn infants delivered by cesarean section (without maternal labor) (p < 0.05) and following labor (NS). There was an initial rapid decrease...

...Annica Sohlström; Hanna Olausson; Kerstin Brismar; Kerstin Uvnäs-Moberg Oxytocin treatment may permanently alter endocrine axes resulting in anti-stress and anabolic effects. However, the nutritional status influences the effects of oxytocin. The specific aims of this study were to investigate...

... whether oxytocin treatment early in life could ameliorate the adverse effects of food restriction in utero. Pups from ad libitum-fed and food-restricted (60% of ad libitum intake during pregnancy) rats were injected subcutaneously once a day with oxytocin or saline on days 1–14 after birth. At adult age...
