| Outline of Final Research Achievements |
The plognosis after treatment for preterm labor were classified into three groups, preterm birth(Group A), delivery within 2 days just after maintenance tocolysis(Group B), no delivery and waiting at home(Group C). In group A, it was important that there was severe inflammation and infection(38% positive, using highly sensitive PCR) in the amnion. And it was firstly reported that the amniotic inflammation (the values of IL-8 in the amniotic fluid) was able to predict the degree of histological chorioamnionitis(stage I or higher >9.9 ng/mL, stage II or higher >17.3 ng/mL and stage III >55.9 ng/mL, respectively).
The differency between Group B and C was slight amniotic inflammation at hospitalization. Group C(amniotic IL-8 <2.6 ng/mL) was able to be considered that the maintenance tocolysis would end from earlier stage of treatment.The knowledge correlated between the delivery just after end of maintenance tocolysis and slihgt amniotic inflammation was for the first time.
