Growth hormone (GH) and prolactin (PRL) in maternal and fetal serum and amniotic fluid were measured simultaneously by radioimmunoassay at term deliveries of 20 normal mothers. The PRL level of amniotic fluid was significantly higher than that of maternal and fetal serum. The fetal GH level was significantly higher than the maternal and amniotic levels of GH. There was no significant correlatio...

Studies using in vitro analysis have shown that the interaction between pulmonary surfactant and vernix caseosa could explain the appearance of amniotic fluid turbidity. That phenomenon is interpreted based on the "roll-up" hypothesis. We tested the roll-up hypothesis by examining the presence of micelles of pulmonary surfactant in human amniotic fluid at term. Amniotic fluid samples were colle...

The determination of enzyme levels in cell-free amniotic fluid has proven useful in assessing fetal maturity and fetal well being, and is being utilized for the prenatal diagnosis of genetic disorders. The activities of amylase, alpha-galactosidase, phosphatidic acid phosphohydrolase, lysozyme and heat-stable alkaline phosphatase in amniotic fluid increase with gestational age and have an estab...

this study aimed to investigate the effects of different doses of sulfadiazine on embryonic chicken pectoral muscles. in total, 100 fertile eggs were obtained and divided into five groups of control (no injection) and sulfadiazine injection at doses of 2, 10, 30, and 70 mg/kg. after hatching, pectoral muscle tissues were harvested from the newly hatched chickens for histopathological examinatio...

Swallowing of amniotic fluid and lung fluid inflow were eliminated in 10 chronically instrumented fetuses. The urachus was ligated, and fetal was urine drained to the outside. At the beginning and the end of 21 experiments of 66 +/- 5 (SE) h duration, all amniotic fluid was temporarily drained to the outside for volume measurement and sampling. Amniotic fluid osmolalities and oncotic pressures ...

the purpose of this investigation was to study and compare the electrophoretic patterns of optic lensproteins of different species of domestic animals at pre- and post-natal ages. optic lenses were removed from the embryo or adult sheep, cattle, goat, camel and chicken at the slaughter-house then homogenized and subjected to sodium dodecylsulfate polyacrylamide gel electrophoresis (sds-page). i...

to study changes in concentrations of some biochemical factors of amniotic fluid, 115 normal goat uteri at different stages of pregnancy were collected from slaughterhouse. after expelling of each fetus accompanied by fetal membranes, 10 ml amniotic fluid was taken from amniotic sac for biochemical analysis. then approximate ages of fetuses were calculated by using age estimation formula. at fi...

results mode of delivery, nicu admission neonatal death and induction of labor. oligohydramnious is associated with a high rate of pregnancy complications and increased perinatal morbidity and mortality. women with oligohydramnious usually have low-birth babies. conclusion however, we can expect a safe and good outcome for pregnant women with oligohydramnious, should proper fetal surveillance a...

CONTEXT No molecular biological tests are available to monitor the ongoing development of human fetuses in vivo. OBJECTIVE To determine whether cell-free fetal messenger RNA (mRNA) in amniotic fluid can be detected using oligonucleotide microarrays to study large-scale gene expression in living human fetuses, with analysis of sex, gestational age, and fetal pathology as variables. DESIGN, S...
