The amniotic fluid volume (AFV) is regulated by several systems, including the in-tramembranous pathway, fetal production (fetal urine and lung fluid) and uptake (fetal swallowing), and the balance of fluid movement via osmotic gradients. The normal AFV across gestation has not been clearly defined; consequently, abnormal volumes are also poorly defined. Actual AFVs can be measured by dye dilut...

Introduction: meconium is the thick, Green - Black, with a bad odor material,  that founded around the third month of pregnancy in the intestines of fetus. 8 to 15 percent of infants has the evidence of meconium stained fluid at birth. In this study the factors affecting maternal and neonatal meconium-stained amniotic fluid be examined. Methods: This study was done in the Vali-e- asr hospital ...

OBJECTIVE This cross-sectional study was carried out to assess the influence of Ramadan fasting on amniotic fluid volume. METHODS For this purpose 2 groups of fasting (n=28) and non-fasting (n=25) pregnant women were investigated for amniotic fluid index (AFI) and deepest vertical pocket of amniotic fluid in November (Ramadan month) of 2001-2002 in Kerman Prenatal Clinics in Kerman, Iran. Mea...

Somatostatin-like immunoreactivity (SLI) is widely distributed in tissues and biological fluids. To determine whether SLI is also present in amniotic fluid, samples obtained by amniocentesis from 30 normal and 27 abnormal pregnancies were studied by radioimmunoassay. Direct incubation of [(125)I-Tyr(1)]tetradecapeptide somatostatin (SRIF) with amniotic fluid resulted in 89% tracer degradation. ...

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...
