Cleft of the secondary palate is one of the most common congenital birth defects in humans. The primary cause of cleft palate formation is a failure of fusion of bilateral palatal shelves, but rupture of the once fused palate has also been suggested to take place in utero. The possibility of post-fusion rupture of the palate in humans has hardly been accepted, mainly because in all the cleft pa...

Purpose:Human amniotic fluid contains several growth factors and hyaluronic acid. It has positive effect in healing the tendon, nerve bone injuries. Human membrane effects on is also used for skin burns complex wounds. We hypothesized that human have stimulating fracture healing. The aim of this study to investigate rat tibial model.

OBJECTIVE To describe the association between echogenic amniotic fluid and first-trimester fetal acrania. METHODS Nine fetuses with acrania were examined between 11 weeks' and 13 weeks 6 days' menstrual age for the presence of echogenic free-floating particles in the amniotic fluid. Cases were classified into 3 types according to the echogenicity of the amniotic fluid: similar to (type 0), sl...

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...

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...

OBJECTIVE Microbial biofilms are communities of sessile microorganisms formed by cells that are attached irreversibly to a substratum or interface or to each other and embedded in a hydrated matrix of extracellular polymeric substances. Microbial biofilms have been implicated in >80% of human infections such as periodontitis, urethritis, endocarditis, and device-associated infections. Thus far,...

Currently it is the hope of both patients and investigators that human progenitor cells and stem cells can be widely used to replace dysfunctional cells within a tissue. It is speculated that such cells may prove to have the potential to treat or cure a myriad of diseases, including Parkinson's and Alzheimer's diseases, heart disease, diabetes, stroke, spinal cord injuries, and burns. A major g...

Phospholipids were extracted from human amniotic fluid by various procedures, including the two most commonly applied to amniotic fluid for evaluation of fetal lung maturity. We find that the yield of phospholipid is greatly procedure dependent. This should be taken into account when one is considering the various reported methods of evaluating fetal lung maturity, because in some of them phosp...

Cells cultured from second trimester human amniotic fluid were characterized in indirect immunofluorescence (IIF) microscopy using specific antibodies against the subunit proteins of different types of cytoskeletal intermediate filaments. Most of the amniotic fluid cell cultures contained only epithelial cells as indicated by the positive keratin-fluorescence in IIF. Five distinct types of kera...

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...
