title: Plasmatic prekallikrein and kallikrein inhibitor in pregnancy, labor and in newborn.
abstract: In order to reveal the possible physiological role of the kallikrein during the stress of birth, the prekallikrein and kallikrein inhibitor were evaluated in 15 pregnant women and in 15 newborns from terminated pregnancies. The results show a very low level of prekallikrein in the funiculus blood at the moment of birth and a still lower level in venous blood 24 hours after birth. No important changes resulted in the mother's blood either in pregnancy, nor at the end of the labour.
