Corticosteroid concentrations were determined in plasma samples obtained from chronically catheterized pig fetuses and their dams during late gestation and parturition. Mean concentrations of 14-20 ng/ml were found in fetal plasma on Days -16 to -10 before delivery and these rose to 40-60 ng/ml between Day -6 and the day of delivery. During the last 8 h of fetal life levels rose rapidly and at birth averaged 168.8 +/- 35.4 ng/ml. Maternal concentrations rose slightly during the last 3 days… CONTINUE READING
