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. Here we report a...

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. ...

Abstract Background Although maternal deaths are rare in developed regions, the morbidity associated with severe postpartum hemorrhage (SPPH) remains a major problem. To determine prevalence and risk factors of SPPH, we analyzed data women who gave birth Guangzhou Medical Centre for Critical Pregnant Women, which received large quantity critically ill obstetric patients were transferred from ot...

Abstract Orchid gynostemium, the fused organ of androecium and gynoecium, ovule development are unique developmental processes. Two DROOPING LEAF/CRABS CLAW (DL/CRC) genes, PeDL1 PeDL2, were identified from Phalaenopsis orchid genome functionally characterized. Phylogenetic analysis indicated that most recent common ancestor orchids contained duplicated DL/CRC-like genes. Temporal spatial expre...

INTRODUCTION Abdominal pregnancy is extremely rare and has historically been defined as an implantation in the peritoneal cavity, exclusive of tubal, ovarian or intraligamentary pregnancy. CASE PRESENTATIONS Three cases are reported. All came from a lower middle-income group and all of them were subjected to surgery.
