| Outline of Final Research Achievements |
We studied the effect of diffuse chorioamniotic hemosiderosis (DCH) on fetal lung development using an experimental DCH model in the second trimester of pregnant rats. At first, we established the animal experimental model of DCH, infused iron dextran into the amniotic cavity of pregnant rats. Next, we confirmed that intra-amniotic iron exposure could induce emphysematous injuries in fetal lung, i.e., arrest of alveolarization, which changes had remain until the adult period．Based on the above results, DCH would be important as a risk factor for serious chronic lung disease and expected further researches for clarifying its pathophysiology and preventive measures.
