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...
INTRODUCTION Fever is a major criterion for clinical chorioamnionitis; yet, many patients with intrapartum fever do not have demonstrable intra-amniotic infection. Some cytokines, such as interleukin (IL)-1, IL-6, interferon-gamma (IFN-γ), and tumor necrosis factor alpha (TNF-α), can induce a fever. The objective of this study was to determine whether maternal plasma concentrations of cytokines...
PURPOSE Amniotic membrane transplantation is currently being used as an alternative approach to treat severe corneal surface disorders refractory to medical therapy. The authors report complications of corneal surface disorders after successful amniotic membrane transplantation. METHODS Case series. RESULTS Twenty-eight patients with corneal surface disorders due to severe chemical burns, c...
A 35-year-old pregnant woman visited our department and had been treated with 100 µg of daily oral levothyroxine for hypothyroidism. An ultrasonography screening was performed at 25 weeks gestation and revealed a fetal goiter and an increased amniotic fluid volume. Fetal hypothyroidism was confirmed by cordocentesis and amniotic hormone levels at 26 weeks gestation. We treated the mother with 2...
The objective of the present study was to compare the success rate of extra-amniotic saline with traction on the cervix with folly catheter for termination of second trimester pregnancies. A randomized trial of extra-amniotic saline infusion versus traction on the cervix with folly catheter was performed on 200 patients with gestational age of 14-28 weeks who required induction of lab...
Background and Aim: Puerperal infection describes any bacterial infection of the genital tract after delivery. It is the cause of 13% of pregnancy related deaths and the fifth leading cause of death. Some studies have addressed the role of meconium-stained amniotic fluid in puerperal infection. The aim of this study was to evaluate the association between meconium-stained amniotic fluid and pue...
purpose: to describe a novel surgical technique for in vivo limbal stem cell cultivation for reconstruction of corneal epithelium in total limbal stem cell deficiency (lscd). methods: patients suffering from chronic total unilateral lscd due to a chemical injury were sequentially included. one small limbal block (2x1 mm) harvested from contralateral healthy eye sutured over the amniotic membran...
Human fibronectin was isolated from second-trimester amniotic fluid, from amniotic fluid obtained at term and from adult plasma. The amniotic-fluid fibronectins had a slightly higher apparent molecular weight on sodium dodecyl sulphate/polyacrylamide-gel electrophoresis than the plasma fibronectin. Early- and late-amniotic-fluid fibronectin had 9.5 and 9.6% carbohydrate respectively, whereas pl...
Ingestion of amniotic fluid and placenta by rats has been shown to enhance opioid-mediated antinociception but not affect the nonopioid-mediated antinociception produced by aspirin, suggesting specificity for opioid-mediated processes. However, enhancement by the active substance(s) in amniotic fluid and placenta (POEF, for placental opioid-enhancing factor) of antinociception produced by other...
Introduction: Amniotic membrane, the innermost layer of extra-embryonic tissue, contains mesenchymal and epithelial stem cells. The amniotic mesenchymal cells have the capability of inhibition of growth of cancer cells. In this research, the effects of amniotic epithelial cells on the viability of cancer cells and the role of apoptosis in this procedure were evaluated. Methods: Amniotic mem...
