On d 16 of gestation, pregnant Sprague-Dawley rats were randomly assigned to either a retinoic acid group (intragastric ATRA at 10 mg/kg body weight) or a vehicle group. We punctured each amniotic sac, and fetuses in the opposite uterine horn served as controls. On d 21 of gestation, the fetuses were delivered by cesarean section. Rats subjected to oligohydramnios exhibited significantly lower lung weights and lung/body weight ratios, and ATRA had no effects on the body or lung weights of oligohydramnios-exposed rats. Lung PDGF-A and -B mRNA expression was significantly lower in oligohydramnios-exposed rats compared with control littermates of maternal vehicle-treated dams. Maternal retinoic acid treatment significantly increased PDGF-A and -B mRNA expression in control and oligohydramnios-exposed rats compared with all rats and oligohydramnios-exposed rats of maternal vehicle-treated dams, respectively. Rats exposed to oligohydramnios exhibited a significantly lower generation of alveolar saccules than did control rats in the maternal retinoic acid- and vehicle-treated groups. In this model, maternal retinoic acid treatment showed no positive effects on oligohydramnios-induced pulmonary hypoplasia in the pseudoglandular stage. ------>tmu_sno=None ------>sno=16117 ------>authors2=Hsiu-Chu Chou ------>authors3=Leng-Fang Wang ------>authors4=Yaw-Dong Lang ------>authors5=Ching-Ying Yeh ------>authors6= ------>authors6_c= ------>authors=Chung-Ming Chen ------>delete_flag=0 ------>SCI_JNo=None ------>authors2_c= ------>publish_area=0 ------>updateTitle=Retinoic acid fails to reverse oligohydramnios-induced pulmonary hypoplasia in fetal rats. ------>language=2 ------>check_flag=None ------>submit_date=None ------>country=None ------>no=5 ------>patent_SDate=None ------>update_bywho=None ------>publish_year=2007 ------>submit_flag=None ------>publish_month=1 |
