Ingestion of amniotic fluid and placenta by rats has been shown to enhance opioid-mediated analgesia. The present studies were designed to examine the effect of several doses and volumes of placenta and amniotic fluid on tail-flick latency in rats treated with 3 mg/kg morphine. The optimal dose of amniotic fluid was found to be 0.25 ml, although 0.50 and 1.0 ml also produced significant enhance...
BACKGROUND The aims of this study were to evaluate the efficacy of current techniques for isolating mesenchymal stem cells (MSCs) from amniotic fluid obtained by second-trimester amniocentesis as well as to determine their differentiation potential. METHODS We collected 50 samples of amniotic fluid by second-trimester amniocentesis. To obtain MSCs from amniotic fluid, the fluid was cultured u...
Swallowing represents a primary physiological function that provides for the ingestion of food and fluid. In precocial species, swallowing activity likely develops in utero to provide for a functional system during the neonatal period. The chronically instrumented ovine fetal preparation has provided the opportunity for recent advances in understanding the regulation of in utero swallowing acti...
The fetal intestinal mucosa is characterized by elevated Toll-like receptor 4 (TLR4) expression, which can lead to the development of necrotizing enterocolitis (NEC)--a devastating inflammatory disease of the premature intestine--upon exposure to microbes. To define endogenous strategies that could reduce TLR4 signaling, we hypothesized that amniotic fluid can inhibit TLR4 signaling within the ...
the site of the placenta. Administration ofanti-D immunoglobulin is routine after invasive procedures in Rh negative patients but is not appropriate for those already sensitised, in whom it would be ineffective.'5 In patients undergoing intra-uterine transfusions, however, fetomaternal haemorrhage may enhance maternal sensitisation. Not only might the disease be worsened in a subsequent pregnan...
UNLABELLED AIMS AND OBJECTIVE(S): Evaluating feto-maternal outcome in pregnancies with abnormal liquor volume. MATERIAL AND METHOD(S) 200 pregnant subjects between 20 and 42 weeks of gestation, who were clinically suspected to have an abnormal amniotic fluid volume (oligohydramnios or polyhydramnios) were subjected to ultrasonographic (USG) assessment of amniotic fluid index. The subjects wer...
The presence of contaminating maternal cells in amniotic fluid is an important, though infrequent, cause of error in karyotyping the fetus. A method of detecting contaminating maternal cells in amniocentesis specimens by determining the HLA phenotype of the cells of amniotic fluid and the mother is described. Tissue typing of 15 amniocentesis specimens was performed, and in 14 cases the fetal o...
stem cells, the last of which can be obtained from fetal tissues, including amniotic fluid [5]. Analyses of human amniotic fluid have been used as safe and reliable screening tools for fetal genetic and congenital diseases for many years [6]. Amniotic fluid contains cells originating from both embryonic and extraembryonic tissues (amnion, placenta, fetus skin, and respiratory, gastrointestinal,...
We developed a new method for an objective assessment of the meconium content in amniotic fluid. By establishing a standard scale through a serial dilution of a known amount of meconium into the amniotic fluid, we developed a new method "mecometer" that can objectively measure the meconium content in meconium-stained amniotic fluid samples. The objectivity and reliability of this mecometer were...
