Symphysis fundus heights (SF) were measured approximately 15 times during pregnancy in a consecutive series of 2941 women with regular menstrual cycles and known last menstrual period. A reference SF chart from 17 to 40 weeks of pregnancy was derived from measurements in 1350 of these women who were healthy, and heights and pre-pregnancy weights within the(More)
OBJECTIVE The aim of this study was to quantify the gene expression of ETA and ETB receptors within the different uterine segments of nonpregnant, normal pregnant, and preeclamptic women. STUDY DESIGN Biopsy samples from the cervix, isthmus, and corpus uteri were obtained from eight nonpregnant, nine term pregnant, and seven preeclamptic women. The(More)
The occurrence of endothelin (ET), a recently discovered polypeptide with potent vasoconstrictor properties, was studied in maternal and umbilical blood and amniotic fluid. The level of ET-like immunoreactivity (ET-LI) in maternal plasma was in most cases below the detection limit of the radioimunoassay, i.e. less than 2 pmol/l. The median concentration of(More)
To study the concentrations of endothelin-1 (ET-1) and its precursor, big ET-1, in samples of amniotic fluid, fetal urine, umbilical arterial and venous blood, retroplacental blood and maternal uterine and brachial venous blood obtained from normal and preeclamptic women. Samples were collected from 31 healthy pregnant women (16 in labor and 15 undergoing(More)
OBJECTIVE To compare the effect of endothelin on isolated resistance arteries from different vascular beds in normal and preeclamptic women before and after pretreatment with the ETA receptor antagonist BQ-123. MATERIALS AND METHODS Resistance arteries from myometrial and omental biopsies obtained at cesarean section of normal pregnant and preeclamptic(More)
OBJECTIVE To assess the occurrence of chronic hypertension and renal disorder after gestations complicated by pregnancy induced hypertension or pre-eclampsia and to define background factors and laboratory analyses at follow up examination which discriminate between women who remain normotensive and those who develop hypertension.

Salbutamol was administered intravenously in doses increasing from 3.75 to 22.5 μg/min to 5 non-diabetic and 7 diabetic women in the last trimester of pregnancy. In diabetic as well as nondiabetic women the diastolic blood pressure fell progressively with increasing doses, and the systolic BP and heart rate increased at doses above 7.5 μg/min. The effect on(More)
The transfer of atenolol and metoprolol to human breast milk was studied in 7 lactating women with hypertension. Concentrations of atenolol and metoprolol in maternal plasma and milk and in plasma of the nursed infants were determined. Blood samples were obtained from the women and from the infants during a dose interval. Milk was collected repeatedly from(More)
Fetal heart rate (FHR) patterns were analysed during last hour of labour and correlated to umbilical artery pH and catecholamine (CA) levels. Fetuses with pathological FHR had significantly higher levels of CA than those with normal FHR. Particulary high levels were found in fetuses with bradycardia and late decelerations. FHR was further analysed by a(More)
