a prospective study of 550 consecutive mothers delivered in amin ob. gyn center of isfahan university was performed to determine the relationships between maternal anemia, placental weight and neonatal birth weight. the important findings were marked placental hypertrophy in anemic mothers. (r= -/9.95) .it is probable that in anemic mothers placental hypertrophy is a compensatory mechanism resp...
Healthy placental development is essential for reproductive success; failure of the feto-maternal interface results in pre-eclampsia and intrauterine growth retardation. We found that grainyhead-like 2 (GRHL2), a CP2-type transcription factor, is highly expressed in chorionic trophoblast cells, including basal chorionic trophoblast (BCT) cells located at the chorioallantoic interface in murine ...
Maternal undernutrition (MUN) during pregnancy may lead to fetal intrauterine growth restriction (IUGR), which itself predisposes to adult risk of obesity, hypertension, and diabetes. IUGR may stem from insufficient maternal nutrient supply or reduced placental nutrient transfer. In addition, a critical role for maternal stress-induced glucocorticoids (GCs) has been suggested to contribute to b...
The efficacy of mother-to-child placental transfer of antibodies specific to malaria blood stage antigens was investigated in the context of placental malaria infection, taking into account IgG specificity and maternal hypergammaglobulinemia. The impact of the resulting maternal antibody transfer on infections in infants up to the age of 6 months was also explored. This study showed that i) pla...
Angiotensin-converting enzyme (ACE) activity in the guinea pig fetal-placental unit was assessed at the different oxygen tensions found in utero, during labor, and at birth. To determine fetal-placental ACE activity, we separately perfused in situ term guinea pig fetuses and their placentas via the umbilical vessels under controlled conditions of flow, temperature, and pH. ACE activity was defi...
One hundred endometrial biopsies of various histological patterns, and material from 10 tubal pregnancies together with their associated uterine decidua, were examined for the presence of human placental lactogen using affinity-purified first and second antibodies and an indirect immunoperoxidase technique. Positive cells in endometrial curettings were seen only in association with an intrauter...
Th e aim of the present study was to evaluate the eff ect of ovine placenta extract, obtained by affi nity chromatography on immobilized wheat germ lectin, on mammogenesis, lactogenesis, and galactopoiesis in pregnant and lactating sheep. Placental extract (100 μg/mL protein concentration) was subcutaneously injected to pregnant sheep in days 1, 4, 7, 10, and 13 of the experiment (totally 10 mL...

BACKGROUND Pregnancy induced hypertension results from defective trophoblast invasion and increased umbilical artery resistance which in turn results in decreased blood supply to the placenta and hence to the foetus. This arterial resistance varies in different cases of PIH thus causing variable effects on placenta and foetus. The objective of this study was to study the morpho-metric changes i...
