T.  aNormal fluctuations in the concentration of corticosteroid and adrenocorticotrophin in the plasma of foetal and pregnant sheep.h[electronic resource]  c1979  aChanges in the concentration of adrenocorticotrophin and corticosteroid in the plasma of pregnant and foetal sheep have been followed at different times of day. Wide fluctuation were seen in the concentrations of both in the foetus and ewe, although no evidence for a diurnal rhythm in the ewe was obtained. The foetal plasma adrenocorticotrophin was higher at 07.00-11.00 h than at 21.00-01-00 h, but no corticosteroid rhythm was observed. A consistently close relationship between maternal and foetal hormone concentrations was not observed. The diurnal rhythm in adrenocorticotrophin concentration in the foetus is discussed in relation to rhythms in indicators of central nervous activity.  aAdrenal cortex hormones  aEndocrinology  aFetus  aMetabolism  aPregnancy  aReproduction  aSheep  aEndocrinologia  aOvino  aPrenhez  aReprodução  aAdrenocorticotropic hormone  aFetal Blood  tHormone and Metabolic Researchgv. 11, n. 3, p. 237-241, Mar. 1979.
