[The role of juxtaglomerular apparatus in regulation of renal hemodinamics]

ROSIVALL László

[The tubuloglomerular feedback mechanism (TGF) is one of the basic processes in the regulation of renal microcirculation. During the activation of TGF the macula densa senses the tubular fluid and ions loads and initiates a rather complex mechanism in juxtaglomerular apparatus resulting in a change of GFR and tubular load. During the activation of TGF there is humoral signaling in the interstitial extraglomerular area. The concentration of the mediator depends on the extraglomerular... tovább »

[Nutritional status of hemodialysis patients, and the role of dietician in the complex care of renal patients]

POLNER Kálmán, KOVÁCS Lívia, HARIS Ágnes

[In chronic renal failure severe cardiovascular complications develop, which are the cause of death in 50% of the patients. According to recent results, behind the accelerated atherosclerosis, malnutrition and inflammation, developing in patients with chronic renal failure, play significant role. Malnutrition and inflammation show close relationship to the serum albumin level, which is an independent predictor of mortality. Authors studied the nutritional parameters of 94 chronically... tovább »

[The prognostic role of placental growth factor in pregnancies complicated by hypertensive disorders]

GULLAI Nóra, MOLVAREC Attila, KAUKER Bea, RIGÓ János Jr.

[Placental growth factor (PlGF) is a member of the proangiogenic VEGF-family; it is mainly produced by throphoblast cells. During the last years numerous studies have shown that circulating PlGF-level in maternal plasma is decreased and its suluble receptor sFlt-1 shows increased expression. In the present study we examined the prognostic accuracy of Alere Triage® PlGF-Assay in hypertensive disorders of pregnancy and its relation with the length of pregnancy. 130 pregnant women were involved in... tovább »
