[Hemostaseologic studies of maternal blood in intrauterine retardation and threatened premature labor]. 1985

T Voigt, and H Voigt

Changes in coagulation of maternal blood in the case of severe gestosis, which indicated a relation to disturbed uteroplacental blood flow, gave rise to study other risk pregnancies and to do specific coagulation analyses. The following parameters were determined in 102 women showing a distinct tendency for premature labor, 20 women patients with suspicion of intrauterine growth retardation, and 18 normal pregnant women: Number of thrombocytes in whole venous blood, fibrinogen, plasminogen, reptilase time, thrombin time. Compared to the control group, a statistically significant increase in the number of thrombocytes was found only in the cohort of women showing signs of imminent premature labor during the 34th to 36th weeks of pregnancy. Both cohorts of patients showed markedly higher levels of plasminogen than the control group over the entire period of gestation studied in this investigation. All other parameters of coagulation showed no significant changes of pathological pregnancies in comparison with normal gravidas.

UI MeSH Term Description Entries
D007752 Obstetric Labor, Premature Onset of OBSTETRIC LABOR before term (TERM BIRTH) but usually after the FETUS has become viable. In humans, it occurs sometime during the 29th through 38th week of PREGNANCY. TOCOLYSIS inhibits premature labor and can prevent the BIRTH of premature infants (INFANT, PREMATURE).

D008431 Maternal-Fetal Exchange Exchange of substances between the maternal blood and the fetal blood at the PLACENTA via PLACENTAL CIRCULATION. The placental barrier excludes microbial or viral transmission. Transplacental Exposure,Exchange, Maternal-Fetal,Exposure, Transplacental,Maternal Fetal Exchange
D010927 Placental Insufficiency Failure of the PLACENTA to deliver an adequate supply of nutrients and OXYGEN to the FETUS. Insufficiency, Placental
D010958 Plasminogen Precursor of plasmin (FIBRINOLYSIN). It is a single-chain beta-globulin of molecular weight 80-90,000 found mostly in association with fibrinogen in plasma; plasminogen activators change it to fibrinolysin. It is used in wound debriding and has been investigated as a thrombolytic agent.

D005340 Fibrinogen Plasma glycoprotein clotted by thrombin, composed of a dimer of three non-identical pairs of polypeptide chains (alpha, beta, gamma) held together by disulfide bonds. Fibrinogen clotting is a sol-gel change involving complex molecular arrangements: whereas fibrinogen is cleaved by thrombin to form polypeptides A and B, the proteolytic action of other enzymes yields different fibrinogen degradation products.
