BACKGROUND Previous studies have shown that morphine consumption during pregnancy may delay embryo development or cause abnormal nervous system function. OBJECTIVE The present study focused on the effect of maternal morphine consumption on development of placenta and blood corticosteron concentration in addictive pregnant mothers. MATERIALS AND METHODS 24 female rats, 170-200g weight, were ...

In the idiopathic intrauterine growth restriction where there are no clear maternal or fetal causes, the placenta may hold the key to its etiology. So, this study was undertaken to look for any placental and umbilical cord abnormality and to establish the relationship of fetal birth weight with placental measurements. In this study, 100 freshly delivered placentae were collected. The placenta a...

Introduction Placenta diffusa though natural in sow and mare is a rare poss1bility in human beings, if the usual differentiation of the chorion into chorion frondosum and chorion leave does no t take place (Brews, 1957). Novak and Woodruff (1967) use the term placenta membranacea almost synonymously. The occurrence of this anomaly is attributed to defective decidua allowing deep implantation of...

Zika virus (ZIKV) crosses the placenta and causes congenital disease. Here we develop an animal model utilizing direct ZIKV inoculation into the uterine wall of pregnant, immunocompetent mice to evaluate transplacental transmission. Intrauterine inoculation at embryonic day (E) 10, but not E14, with African, Asian or American strains of ZIKV reduces fetal viability and increases infection of pl...

The placenta is the special pregnancy organ that links a mother to the child for the transport of fetal nutrition through umbilical cord. Preeclampsia is a major disorder of pregnancy which mainly originates in the placenta and is associated with retarded fetal and placental growth. The aim of this study was to compare the morphometric measures of placenta in pregnancies complicated by Preeclam...

Background: Hypertensive pregnancy may be responsible for vascular damage, enhanced systemic inflammation and insulin resistance in the placenta as oxygen nutrient transfer is impaired oxidative stress generated affecting placental growth development. Placental pattern hypertensive pregnancies shows a variable owing to insufficiency. Method: The study was carried out on 80 sets placentae, mothe...

Placental adhesive disorders involve the growth of placental tissue into or through the uterine wall. Among these disorders, placenta percreta is the rarest one. However, it may cause significant complications. This report aimed to report a neglected patient with placenta percreta who developed uterine rupture with life-threatening late postpartum intra-abdominal hemorrhage. On admission, the p...
