amniotic fluid volume (afv) is one of the important parameters in the assessment of fetal well-being. the ability of ultrasound measurements to represent the actual afv is unproven. this study was undertaken to compare correlation of conventional amniotic fluid index (afi) and radial amniotic fluid index (rafi) as a new method with actual fluid volume on phantom. as an experimental study, 10 to...

background: cadmium is an extremely toxic metal with ubiquitous environmental distribution. cadmium is a potent reproductive and developmental toxic agent, and intensive environmental exposure to this substance has been reported among the residents of tehran. in this study, we investigated the correlation between amniotic fluid cadmium levels and the risk of preeclampsia, prematurity and low bi...

background: there is evidence of antibacterial properties of human chorioamniotic layer. however, the distinctive contribution of its individual parts, amniotic and chorionic membranes, to these effects is still unknown. the aim of present study was comparison of the antibacterial effects between amniotic and chorionic membranes. methods: chorioamniotic layer was removed from placenta belonging...

UNLABELLED Amniotic fluid Gram stain and culture have been utilized as laboratory tests of microbial invasion of the amniotic cavity. The Gram stain of amniotic fluid has a low sensitivity in the detection of clinical infection or microbial invasion of the amniotic cavity, and amniotic fluid culture results are not immediately available for management decisions. Glucose concentration is used to...

To test the hypothesis that a substance present in the amniotic fluid could serve as a regulator of amniotic fluid volume, we drained and discarded amniotic fluid while replacing it with lactated Ringer solution that was isotonic to amniotic fluid. Seven ewes with singleton fetuses at 119 +/- 1 days of gestation (mean +/- SE) were instrumented with multiple indwelling catheters in the pedal art...

background different methods for dressing of donor site of skin graft in burn patients have similarly pain, limitation of mobility of donor site and local complications such as infection and scar. amniotic membrane has used for improvement of healing in some wounds. accordingly in this study amnion was used as biologic dressing for donor site of skin graft to evaluate it’s efficacy in improveme...

PROBLEM Inflammation and infection play a major role in preterm birth. The purpose of this study was to (i) determine the prevalence and clinical significance of sterile intra-amniotic inflammation and (ii) examine the relationship between amniotic fluid (AF) concentrations of high mobility group box-1 (HMGB1) and the interval from amniocentesis to delivery in patients with sterile intra-amniot...

PURPOSE Surgery to reconstruct the ocular surface is greatly facilitated by the use of amniotic membrane, either as a biologic drape or, more recently, as a substrate for the transplantation of cultivated corneal epithelial cells. This study was designed to compare the usefulness of intact and denuded human amniotic membranes as a substrate for corneal epithelial cell culture. METHODS Small (...
