  1. 6. Studies on Prostanoid Production in the Umbilicoplacental Circulation

    Författare :Pia Saldeen; Malmö Reproduktionsmedicin; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; gynaecology; Obstetrics; Umbilical; Thromboxane; Pulsatility Index; Prostacyclin; Pregnancy; Placenta; Peroxidation; Growth restriction; Endoperoxides; Endothelium; Doppler; Diabetes; sexualitet; reproduktion; andrologi; gynekologi; andrology; reproduction; sexuality; Obstetrik;

    Sammanfattning : The fetoplacental circulation is a low pressure system with a high vascular prostacyclin to thromboxane (Pc/Tx)synthesis ratio. In intrauterin growth restriction (IUGR) and diabetes the prostanoid balance may be altered. LÄS MER

  3. 7. Maternal renal artery Doppler velocimetry in normal and hypertensive pregnancies

    Författare :Marius Kublickas; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :Atrial natriuretic factor Cyclicguanosine monophosphate Doppler ultrasoundKidney Modeling Preeclampsia Pregnancy Preg-nancy induced hypertension Pulsatility index Re-nal artery Renal blood flow Repeatability.Stockholm 1966;

    Sammanfattning : Background: The measurement of effective renal plasma flow (ERPF) by calculation of p-aminohippurate (PAH) clearance is an invasive, time-consuming procedure. In nonpregnant humans, the clearance of isotopes can be used to measure renal plasma flow, but the use of these radioactive substances during pregnancy is unsuitable. LÄS MER

  4. 8. Renal hemodynamics in renal artery stenosis and angiotensin II-dependent hypertension. Pathophysiological and diagnostic aspects

    Författare :Aso Saeed; Göteborgs universitet; []
    Nyckelord :angiotensin II; autoregulation of renal blood flow; color duplex sonography; endothelin-1; oxidative stress; renal artery stenosis; renal hemodynamics; renovascular hypertension;

    Sammanfattning : Patients with renovascular hypertension have a poor renal and cardiovascular prognosis. To improve the care of these patients, we need to increase knowledge about the pathophysiological mechanisms involved. LÄS MER

  5. 9. Hypoglycaemia in pregnancy : hypoglycaemic clamp studies during and after pregnancy in women with IDDM

    Författare :Anders Björklund; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :Adrenaline; cardiotocography; cognitive function; Doppler; fetal; fetal monitoring; growth hormone; hormonal counterregulation; hypoglycaemia; insulin; insulin-dependent diabetes mellitus; metabolic clearance rate; placenta; pregnancy; subjective symptoms;

    Sammanfattning : Problem: In pregnant women with IDDM a strict insulin regimen is generally instituted, which permits the possibility of a normal fetal outcome. This, however, increases the risk of hypoglycaemia, and a high prevalence of severe hypoglycaemia has been reported during pregnancy in these women. LÄS MER
