...) quartiles of MAP change were associated with a decrease in sCr. A similar but stronger correlation was found among 14 patients treated with norepinephrine either after failing midodrine/octreotide (n = 10) or de novo (n = 4; p = 0.002), where a rise in MAP of +19.2 to 25 mm Hg was associated with a larger...

.... Simultaneously, myocardial perfusion was evaluated by 99m Tc-MIBI-SPECT. In addition, plasma norepinephrine and ET-1 concentrations were measured at baseline and at peak exercise. Results: The segmental radionuclide analysis showed a greater ischemic degree in hypertensive uremic patients. Yet, we were able...

..., extracorporeal bicarbonate haemodialysis (Na + D =138 mmol/l). Body fluid distribution and the release of vasoactive hormones (plasma renin activity, aldosterone, norepinephrine, epinephrine, and atrial natriuretic peptide) were investigated. Haemodialysis with constant ultrafiltration rate and constant...

...Anisul Islam; Miroslaw Smorgorzewski; Maysa A. Zayed; Shaul G. Massry Norepinephrine (NE) content, release and uptake by brain synaptosomes are reduced in chronic renal failure (CRF), and this has been attributed to the state of secondary hyperparathyroidism. The decrease in NE content in CRF could...

... vasopressin or norepinephrine in Eagle’s minimum essential medium, whereas glomeruli from rabbits recovering from ischemic ARF were refractory to the vasoconstrictor agents. The findings suggest that glomerular refractoriness to contractile stimuli does not provide resistance to an additional renal ischemia...

... catecholamines were constantly high. A dialysis-induced fall of all sulfated catecholamines and epinephrine was observed. Norepinephrine decreased in 5 patients and increased in 4, with a strong inverse correlation between predialysis norepinephrine and Δ norepinephrine (p < 0.0001). No correlation...

...Klaus Schafferhans; Ekkehart Heidbreder; Daniela Grimm; August Heidland The effect of the atrial natriuretic factor (ANF) on early norepinephrine-induced acute renal failure (ARF) was investigated. In anaesthetized female Sprague-Dawley rats, weighing 247 ± 36 g, ARF of the left kidneys was induced...

... and WK rats: mean arterial blood pressure (concious unrestrained rats) was lower, intravascular volume was higher, total body sodium was slightly higher, and plasma angiotensin II or norepinephrine levels were not different from CO groups. The acute hypotensive and chronotrophic effect of intravenous PTH...

...Rodger Loutzenhiser; Charles Horton; Murray Epstein The effects of the organic calcium antagonist diltiazem (DIL) upon the alterations in renal hemodynamics produced by norepinephrine (NE) were assessed in the isolated perfused rat kidney. In the presence of propranolol, the administration of NE (3...

...Clinton N. Corder; Jashwant Sharma; Robert H. McDonald, Jr. Plasma norepinephrine (NE), epinephrine (EPI), dopamine (DPM), dopamine β-hydroxylase (DBH), and renin were measured in patients undergoing maintenance hemodialysis. The predialysis NE, EPI and DPM concentrations were lower than normal...

...-pressure cardiopulmonary receptors and high-pressure arterial baroreceptors in response to changes in blood volume. Thus, a decrease in blood volume or in effective circulating blood volume leads to an increase in renal nerve activity, release of norepinephrine, α-adrenergic stimulation and increased...

...Raymond Lake Plasma concentrations of norepinephrine (NE) appear to reflect sympathetic nervous system (SNS) tone. Plasma NE increases substantially when the SNS is stressed by acute postural change or physical exercise. Standing up from the recumbent position elevates NE by about 90% in healthy...

...Robert W. Schrier; Tomas Berl; Judith A. Harbottle; Keith M. McDonald The in vivo mechanisms whereby systemic α- and β-adrenergic stimulation exert opposing effects on renal water excretion are reviewed. An extrarenal mechanism is suggested since the effect of intravenous infusion of norepinephrine...
