abstract 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 weigh...

Background: Previous studies have shown that morphine consumption during pregnancy may delay embryo development or cause abnormal nervous system function .The most attention of research focuses on the embryo, whereas it was not attended to the placenta as an important organ which is affected by opioides. The present study focused on the effect of maternal morphine consumption on development of ...

Background: Experiments have shown that opioid drugs abuse during pregnancy can cause a delay in the development of the placenta. In mammals, the placenta is the most important channel for the exchange of Materialss between the maternal and fetal bloods. The present study investigates the time-dependent effect of the addiction duration of maternal morphine consumption during pregnancy. Material...

Physiol. 215(l) 2051-210. 1968.-The rate of accumulation and distribution of “gFe in the fetus, placenta, and accessory tissues was studied at different stages of gestation following iv injection of zgFe. There is a steady increase in percent of SgFe and in the to...

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...

PURPOSE The purpose of this retrospective cohort study was to elucidate whether the location of placenta below uterine incision in cesarean section is important in the development of maternal complications in placenta previa patients. METHODS The study was conducted on 409 patients 414 parturition at 3 hospitals in affiliation with the Catholic Medical Center, Seoul, Korea from May 1999 to De...

METHODS Female Wistar rats were exposed to filtered air (F) or to concentrated fine particulate matter (P) for 15 days. After mating, the rats were divided into four groups and again exposed to F or P (FF, FP, PF, PP) beginning on day 6 of pregnancy. At embryonic day 19, the placenta was collected. The placental structure, the protein and gene expression of TGFβ1, VEGF-A, and its receptor Flk-1...

In spite of much research work within recent years comparatively little has been discovered concerning the causation of accidental haemorrhage. Most writers, including Gordon Ley1 and Whitridge Williams,2 have agreed in ascribing it to toxaemia of pregnancy, while others, led by James Young of Edinburgh, have looked upon the toxaemia as secondary to, and consequent upon the haemorrhage. Accordi...
