Biochemical evaluation of amniotic fluid during different stages of gestation in the goat
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...
متن کاملReproducibility of measuring amniotic fluid index and single deepest vertical pool throughout gestation.
OBJECTIVE The aim of this study is to assess the intraobserver and interobserver reproducibility of measurement of amniotic fluid index (AFI) and single deepest vertical pool (SDVP), also known as the maximal vertical pocket. METHODS A total of 175 fetuses were evaluated. For each fetus, two observers acquired duplicate sets of AFI and SDVP. Measurement differences were expressed as actual an...
متن کاملAmniotic fluid and hemodynamic model in monochorionic twin pregnancies and twin-twin transfusion syndrome.
We developed a mathematical model of monochorionic twin pregnancies and twin-twin transfusion syndrome (TTTS), combining both fetal fluid dynamics and fetoplacental growth and circulation alterations and assuming that transplacental fluid flow from mother to fetus accounts for normal fetal and amniotic fluid volumes. Ten coupled differential equations, describing fetal total body and amniotic f...
متن کاملHuman mid-gestation amniotic fluid contains interleukin-16 bioactivity.
CD4-positive cells are detectable in the human fetal gastrointestinal tract from 11 weeks of gestation. Interleukin-16 (IL-16) is a chemoattractant for CD4(+) cells and, via fetal swallowing of amniotic fluid, could mediate the influx of CD4(+) cells into the fetal gut. We have shown that IL-16 was detectable in human amniotic fluid at 16-18 weeks of gestation (mid-pregnancy) but was not detect...
متن کاملOutcome of monochorionic twin pregnancies with moderate amniotic fluid discordance adjoining twin-twin transfusion syndrome.
OBJECTIVES This study aimed to assess the perinatal outcome in monochorionic diamniotic (MD) twin pregnancies complicated by amniotic fluid discordance (AFD) adjoining twin-twin transfusion syndrome (TTTS). METHODS An observational study of 84 consecutive MD twin pregnancies complicated by AFD that resembled TTTS was conducted. AFD adjoining TTTS was defined by a maximal vertical pocket of am...
