Renal perfusion in blacks: alterations caused by insuppressibility of intrarenal renin with salt.
We have reported that an increased intrarenal renin-angiotensin system activity may be responsible for the reduction in renal plasma flow (RPF) in apparently healthy blacks in comparison to healthy whites during high salt balance. To ascertain whether these differences only exist in the high salt state, we performed the following study, concentrating on the manipulation of the renin system duri...
متن کاملThe role of myocardial perfusion SPECT in short-term cardiac prognosis of end-stage renal disease
Introduction: One of the most important causes of death in patients with end-stage renal disease (ESRD) and even after kidney transplantation is cardiovascular diseases. Thus, cardiac evaluation is of utmost importance in the management of these patients especially during preoperative work up before renal transplantation. The aim of present study is to evaluate the role of myoc...

The metlhodls usedl for perftusinig isolatedi renal tul)ules are generally clifferent from microptuncture, as are the prob)lems encounteredl. Altlhotuglh I will concentrate maiinly on the teclhnical aslpects of perfuision, it seems to me most important to evaluate to wlhat extent the restults are p)ertinent to the stt(ly of kidney function.

متن کاملThe Effect of Altered Renal Perfusion Pressure
Controversy persists regarding the role of tubular reabsorption and secretion in the renal handling of digoxin. To determine the effect of reduction in renal perfusion pressure and blood flow on digoxin clearance during acute and chronic digoxin administration, renal clearances of digoxin and inulin were measured in pentobarbital-anesthetized dogs before and after repeated unilateral renal arte...
متن کاملNeural control of renal medullary perfusion.
There is strong evidence that the renal medullary circulation plays a key role in long-term blood pressure control. This, and evidence implicating sympathetic overactivity in development of hypertension, provides the need for understanding how sympathetic nerves affect medullary blood flow (MBF). The precise vascular elements that regulate MBF under physiological conditions are unknown, but lik...
