objective: in previous studies it has been emphasized that the site of morphine action may be either in the embryo or the placenta. in the present study, we attempt to identify the site of morphine action on the fetal section of wistar rat placenta by using c14-morphine. materials and methods: in this study (experimental), female wistar rats (weights: 170-200 g) were mated with male rats and th...

background: placenta previa (pp) is an obstetric complication that can affect maternal and fetal morbidity and mortality. its prevalence is rising due to cesarean sections. there is no quantitative data of placenta in pp. in this study, quantitative parameters of placenta in cases with pp in comparison with normally implanted controls were investigated. methods: in this quasi experimental study...

The placental adhesive disorders such as placenta accreta and placenta percreta are the rare causes of serious obstetric hemorrhages. They are associated with high maternal morbidity and mortality. Placenta percreta is usually diagnosed in the third trimester of pregnancy as a massive postpartum hemorrhage when an attempt to remove the placenta reveals lack of a cleavage plane.

Background and aim: Horseshoe placenta is a variant of ring-shaped placenta. Ring-shaped placenta is a rare anomaly seen in fewer than 1 in 6000 deliveries, which could be seen as horseshoe shape due to atrophy in a portion of the ring. This report refers to a possible relationship between the horseshoe shape placenta and preterm labor; although it has not been yet validated in the literature. ...
