  1. 21. Effects of acute metabolic interventions on hemodynamics, endothelial function and forearm glucose uptake

    Författare :Andreas Fugmann; Uppsala universitet; []
    Nyckelord :Medical sciences; Insulin; glucose; lipids; bloodflow; endothelium; MEDICIN OCH VÅRD; MEDICINE; MEDICIN; Medicine; medicin;

    Sammanfattning : Hyperinsulinemia is known to augment endothelium-dependent.vasodilation (EDV). If physiological levels of insulin lead to peripheral, vasodilation and if this vasodilation is an independent determinant of skeletal muscle glucose uptake is however under debate. LÄS MER

  3. 22. Endothelium-derived substances and regional hemodynamics in experimental hypertension

    Författare :Sven-Olof Granstam; Uppsala universitet; []
    Nyckelord :Medical sciences; nitric oxide; endothelin; hypertension; rats; SHR; hemodynamics; blood pressure; blood flow; acetylcholine; carvedilol; microsphere method; MEDICIN OCH VÅRD; MEDICINE; MEDICIN; Medicine; medicin;

    Sammanfattning : The spontaneously hypertensive rat (SHR), a model for experimental hypertension, is considered to have similarities with essential hypertension in humans. Differences between SHR and normotensive Wistar Kyoto rats (WKY) in the vascular response to endothelial-derived substances such as nitric oxide (NO) have been intensively studied in vitro. LÄS MER

  4. 23. Cardiovascular and sympatho-adrenal responses to mental stress with special reference to the regulation of human forearm blood flow

    Författare :Madeleine Lindqvist; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :adrenaline; axillary blockade; beta-receptor blockader; calcium channel blockers; cholinergic blockingagents; felodipine; hypertension-primary; noradrenaline; skeletal muscle; sodium nitroprusside; stress-psychologicai; vascular resistance;

    Sammanfattning : The cardiovascular and sympatho-adrenal responses to a standardized mental stress test (Stroop's colour word conflict test CWT) were studied in 63 healthy and 11 hypertensive men by intraarterial pressure measurements, forearm blood flow by occlusion plethysmography and noradrenaline (NA) and adrenaline (ADR) determinations in arterial and venous plasma. One study included central hemodynamics by right heart catheterization and NA turnover by an isotope dilution method, permitting studies of NA kinetics in the whole body and in a regional vascular bed (the forearm) in hypertensive patients and age-matched controls.

  5. 24. Vascular functions in infants, children and their mothers

    Författare :Helena Martin; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : The function of the microvascular system was studied during early postnatal circulatory adaptation and in early-onset neonatal sepsis. We also studied large and small artery functions in infants and schoolchildren of low birthweight, a risk factor related to later development of cardiovascular disease and hypertension. LÄS MER

  7. 25. Antihypertensive treatment and endothelial vasodilatory function

    Författare :Bengt von zur Mühlen; Uppsala universitet; []
    Nyckelord :Medical sciences; Hypertension; endothelium; nitric oxide; antihypertensive treatment; MEDICIN OCH VÅRD; MEDICINE; MEDICIN; Medicine; medicin;

    Sammanfattning : The endothelium integrates vascular tone by the synthesis of vasoactive substances secreted abluminally to the underlying vascular smooth muscle. Endothelial function has previously been shown to be impaired in primary, secondary and experimental forms of hypertension. LÄS MER
