Introduction: Iron plays an important role in myelination. Ferritin is a reliable indicator of the tissue iron store and umbilical cord ferritin level reflects the in utero iron stores. Objective is to study the effect of the umbilical cord ferritin level on the ABR recording in the newborn.   Materials and Methods: The study was conducted in a ...

Reductions in uterine perfusion pressure (RUPP) in pregnant rats is associated with increased tumor necrosis factor-alpha (TNF-alpha). This study was designed to determine the role of endogenous TNF-alpha in mediating changes in arterial pressure and endothelin-1 (ET-1) in RUPP rats. To achieve this goal we examined the effect of RUPP in the presence and absence of a TNF-alpha-soluble receptor,...

To study vascular endothelial growth factor (VEGF) and placenta growth factor (PlGF) concentrations and their possible binders, serum from 22 non-pregnant and 55 pregnant women (15 at weeks 10-13; 40 at term), umbilical vein (n = 24) and artery (n = 13) and amniotic fluid (a pool of 50 at weeks 15-17; 11 at term) were assessed for VEGF and PlGF by an enzyme-linked immunosorbent assay. In amniot...

Pregnancy induced hypertension (PIH) is major contributor to maternal death in developing countries. Endothelin-1 (ET-1) is the most potent vasoconstriction agent known and its serum levels are increased in PIH. Therefore it is important to elucidate maternal and neonatal factors which influence endothelin-1 serum levels. 100 pathological pregnancies and 88 controls were analyzed for blood endo...

OBJECTIVES The aim of the study was to determine serum adiponectin levels among patients with gestational diabetes mellitus (GDM) and normal pregnant women without glucose intolerance, and to investigate the relationship between these levels and clinical factors at the time of the diagnosis, at delivery and in the post-partum period. MATERIAL AND METHODS The subjects' serum adiponectin concen...

INTRODUCTION: Endometriosis, commonly occurs in the pelvic organs, mostly the ovaries, with dysmenorrhea, menorrhagia Umbilical endometriosis is rare .Symptoms include umbilical masses with swelling and pain.. SO it is often not recognized  based on  its clinical appearance. PRESENTATION OF CASE: A 32-year old female, was presented  with  umbilical bulging and  mild cyclic umblical  pain. with...

We have examined the effects of purified human alpha-thrombin on factor VIII antigen (FVIII-Ag) release by human umbilical vein endothelial cells in culture. Alpha-thrombin induced a time and dose-dependent release of FVIII-Ag into supernatant medium. Alpha-thrombin-mediated FVIII-Ag release was not dependent on protein synthesis and was observed in both serum-free and serum-containing media. F...

Although the literature on the permeability of the placenta to many substances either of a metabolic or foreign origin is extensive, there is a paucity of data on comparisons of maternal and infant total base. In 1920 Stander and Tyler (1) reported identical values for the ash of maternal and fetal plasma, while Levy-Solal, Dalsace, and Gutman (2) in 1934 reported the maternal and fetal plasma ...

OBJECTIVE Anti-endothelial cell antibodies in serum of patients with different inflammatory diseases can be detected by a whole cell enzyme-linked immunosorbant assay, using primary cultures of human umbilical vein endothelial cells. To avoid repeated isolation, it would be of great value if an immortal endothelial cell line could be used to perform anti-endothelial cell antibody assays. METH...

A method is described for measurement of human chorionic somatomammotropin (HCS) by use of a double-antibody technique, for concentrations ranging from 2 ng/ml to 20 tg/mI. The cross-reactive characteristics of rabbit anti-human HCS serum No. CT 3399 from NIAMD are explored. A dilution plan is presented utilizing a standard curve from 0.75 to 80 ng/ml. Concentrations (mean and ranges) for HCS i...
