The study presented here was performed to determine the pharmacokinetics of intravenously administered clindamycin in pregnant women. Seven pregnant women treated with clindamycin were recruited. Maternal blood and arterial and venous umbilical cord blood samples were obtained. Maternal clindamycin concentrations were analyzed by nonlinear mixed-effects modeling with the NONMEM program. The dat...

The initiating event in preeclampsia is thought be to reduced uteroplacental perfusion. Although we have reported previously that chronic reductions in uterine perfusion pressure (RUPP) in pregnant rats results in hypertension and enhanced endothelin production, the factors linking placental ischemia and endothelial cell activation remain unclear. The purpose of this study was to determine the ...

BACKGROUND Fetal growth restriction (FGR) is a condition with heterogeneous pathophysiology which characterized by fetal weight less than the tenth percentile for gestational age. Several factors have impact on maternal, placental and fetal due to growth restriction. OBJECTIVE The aim of this study was to investigate the relationship between levels of leptin in the cord, and serum leptin of m...

OBJECTIVE To compare the maternal and umbilical cord serum selenium concentrations in Low and normal birth weight neonates. MATERIALS AND METHODS A case-control study was carried out in Vali-Asr and Akbarabadi Hospitals (Jan. to Dec. 2013). Two groups; case group; 91 mothers who delivered a low birth weight (LBW) neonate and control group; 86 subjects who delivered a normal birth weight neona...

The heptapeptide angiotensin-(1-7) is a circulating biologically active product of the renin-angiotensin system. In this study, we evaluated the role of the vascular endothelium in the formation of angiotensin-(1-7). Metabolism of 125I-angiotensin I was investigated using confluent cultured bovine and human aortic and umbilical vein endothelial cells. The fetal calf serum-supplemented medium wa...

The aim of this study was to investigate if anthropometric parameters are associated with both leptin and soluble leptin receptor (sLEPR) levels in newborns and their mothers. This cross-sectional study was performed in 118 mother-newborn pairs. The venous blood sample of mothers was taken before delivery and immediately after delivery an umbilical cord blood sample was collected. Levels of lep...

OBJECTIVES To investigate the role of biochemical changes in the umbilical cord and placenta in developing preeclampsia (PE). SUBJECTS AND METHODS Thirty women with PE and 15 healthy pregnant women as controls were enrolled in this study. Vascular endothelial growth factor (VEGF), soluble vascular endothelial growth factor receptor 1 (sVEGFR-1), platelet-derived endothelial cell growth factor...

Objective: This study was undertaken to describe the pharmacokinetics of intravenously administered clindamycin in pregnant women. Study Design: Pregnant women were recruited who needed treatment with clindamycin in the prevention of neonatal group B streptococcal disease or of endocarditis (900 mg every 8 hours and 600 mg every 6 hours respectively). Following delivery, both arterial and venou...

Transplacental transfer of genotoxic material has been determined by measuring the polycyclic aromatic hydrocarbon-albumin adduct level in serum isolated from the mother and the umbilical cord blood using a competitive enzyme-linked immunoadsorbent assay (ELISA) and the antibody (8E11( against benzo[a]pyrene (B[a]P) tetrols. Smoking women (median = 5.54 fmol B[a]P eq/micrograms albumin; n = 21 ...
