[The activity of L-cystine-aminopeptidase (oxytocinase) in the serum of pregnant women during intravenous application of oxytocin (author's transl)]. 1978

K Schumann, and M Fährmann

The oxytocinase levels have been tested prior to, during and after oxytocin challenge tests in 42 pregnant women. There was no relation between labour and the activity of the enzyme. There was no change in the activity during and after oxytocin infusion. Repeated challenge tests did not change these results. The use of the oxytocinase as a parameter of placental function is not influenced by oxytocin infusions.

UI MeSH Term Description Entries
D007743 Labor, Obstetric The repetitive uterine contraction during childbirth which is associated with the progressive dilation of the uterine cervix (CERVIX UTERI). Successful labor results in the expulsion of the FETUS and PLACENTA. Obstetric labor can be spontaneous or induced (LABOR, INDUCED). Obstetric Labor
D010121 Oxytocin A nonapeptide hormone released from the neurohypophysis (PITUITARY GLAND, POSTERIOR). It differs from VASOPRESSIN by two amino acids at residues 3 and 8. Oxytocin acts on SMOOTH MUSCLE CELLS, such as causing UTERINE CONTRACTIONS and MILK EJECTION. Ocytocin,Pitocin,Syntocinon
