Peripheral blood samples of 10 healthy non-gravids were taken as controls. Our results present a marked increase of beta-endorphin levels with the progression of gestation, reaching a peak of 3960 pg/g at term. The data obtained indicate that beta-endorphin plays an important role in pregnancy and delivery regulation.Beta-endorphinFetal and neonatal pancreasPregnancy and delivery regulation
