Outline of Final Research Achievements |
Previously we reported that the first report of uncontrollable subchorionic and retroplacental haemorrhage inducing preterm labour in complete PAI-1 deficiency in a human To determine the role of PAI-1 in maintenance of pregnancy, we collected the plasma from 1032 pregnant women in the 1st trimester. The outcome of the pregnancy was examined especially on rate of abortion, preterm delivery and abruptio placentae. The PAI-1 level of abortion with uterine contraction tended to be low compared to normal pregnancy. PAI-1 level was less than 10ng/mL(very low level) in a case out of 3 cases of abruptio placentae. These results suggest that PAI-1 is involved in attachment of feto-maternal interface. We found that PAI-1 staining was weak or absence in the cases of abortion with uterine contraction compared to normal pregnancy.
