Abstract/OtherAbstract:
OBJECTIVE: To compare the plasminogen activators (tPA, uPA) and their inhibitors (PAI-1, PAI-2) at different gestational ages, related to levels in women at term and non-pregnant women. METHODS: Blood samples were obtained by puncture of the umbilical cord vein, in gestational weeks 39-40 (n = 21), 30-32 (n = 15), and 27-29 (n = 9). Analyses of PA and PAI antigen concentrations and of PAI-1 activity were performed. RESULTS: The mean tPA antigen level in term newborn infants was 14.5 micrograms/l compared to the premature newborns (7.0 micrograms/l), women at term (7.5 micrograms/l) and non-pregnant women (2.3 micrograms/l). PAI-1 activity and PAI-2 antigen concentrations were also higher in term newborn than in premature infants. CONCLUSIONS: The plasma levels of the plasminogen activators and inhibitors are higher in term newborn compared with premature newborn infants, reflecting maturation of protein synthesis.
