  1. 1. Glomerular filtration rate in adults : a single sample plasma clearance method based on the mean sojurn time

    Författare :Margareta Gref; Kjell Karp; Börje Ljungberg; Umeå universitet; []
    Nyckelord :Clinical Physiology; klinisk fysiologi;

    Sammanfattning : Glomerular filtration rate (GFR) is a key parameter in evaluating kidney function. After a bolus injection of an exogenous GFR marker in plasma an accurate determination of GFR can be made by measuring the marker concentration in plasma during the excretion. LÄS MER

  3. 2. Physiological and morphological aspects of the glomerular barrier in health and disease. Results based on experimental studies in the rat

    Författare :Clara Hjalmarsson; Göteborgs universitet; []
    Nyckelord :glomerular permeability; isolated perfused kidney; charge; endothelial surface layer; glycocalyx; electron microscopy; orosomucoid; nephrotic syndrome; proteinuria;

    Sammanfattning : Tremendous amounts of fluid are filtered every day through the kidneys. The anastomosing capillary loops surrounded by Bowman s capsule, forming the glomerulus, function in accordance with the interplay between the hydrostatic and the colloid osmotic pressure. The result of the action of these mechanisms is the production of primary urine. LÄS MER

  4. 3. Functional Aspects of the Juxtaglomerular Apparatus : Control of Glomerular Filtration and Renin Release

    Författare :Johan Sällström; Erik Persson; Peter Hansell; Jürgen Schnermann; Uppsala universitet; []
    Nyckelord :MEDICINE; MEDICIN; Medical Cell Biology; Medicinsk cellbiologi;

    Sammanfattning : The juxtaglomerular apparatus (JGA) is a control unit of the kidney, that regulates glomerular filtration rate (GFR) and renin release, and hence extracellular volume and blood pressure. The tubuloglomerular feedback (TGF) mechanism is a negative feedback loop that regulates GFR. LÄS MER

  5. 4. Properties of the endothelial cells and the glomerular barrier

    Författare :Jenny Sörensson; Göteborgs universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Capillary permeability; kidney glomerulus physiology; isolated perfused kidney; endothelium; orosomucoid; charge; horseradish peroxidase; inflammation; proteoglycan; cAMP.;

    Sammanfattning : The kidneys are vital organs that filter plasma to produce 180 liters of primary urine per day. Only 1% of this volume is excreted and the rest is reabsorbed. Naturally, such huge amounts of fluid must be well controlled to maintain the homeostasis, which is a prerequisite for life. LÄS MER

  7. 5. A Study on Endoscopic Live Donor Nephrectomy and Elevated Intraperitoneal Pressure

    Författare :Pernilla Lindström; Bengt Rippe; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Surgery; Candesartan; cardiac output; glomerular filtration rate; hand-assisted laparoscopy; hand-assisted retroperitoneoscopy; kidney; living donor nephrectomy; morbidity; pneumoperitoneum; rat; renal transplantation; Kirurgi; Surgery; Kirurgi; Surgery; kirurgi;

    Sammanfattning : Live donor nephrectomy (LDN) is a unique surgical challenge where surgery is performed on healthy individuals. It is of great importance to keep the morbidity of donors as low as possible, as well as harvesting a kidney in optimal condition. Lowering morbidity is the motive for introducing the endoscopic technique in LDN. LÄS MER
