Aortic Stiffening, Aortic Blood Flow Reversal, and Renal Blood Flow
Hypertension, 2015See related article, pp 61–67 Normal arterial aging is characterized by arterial enlargement, wall thickening, and stiffening, which predominates at large arteries.1 Patients with chronic kidney disease (CKD) have an early vascular aging,2 characterized by an accelerated arterial enlargement and stiffening, which occurs in parallel with the decline ...

Renal Blood Flow in Experimental Hydronephrosis
Acta Physiologica Scandinavica, 1957Summary.Renal blood flow has been estimated by measuring the venous return from both kidneys simultaneously in acute experiments on rabbits.Control experiments showed no significant difference between the two normal kidneys.From 1 to 17 weeks after ligation of one ureter the blood flow was reduced to about 40 percent on the obstructed side while there ...

Blood Flow to Experimental Renal Tumors
Investigative Radiology, 1986Radiolabeled microsphere techniques were used to measure renal blood flow (RBF) in rabbit kidneys with 14- to 16-day-old experimentally induced renal tumors. VX-2 carcinoma cells (25 microliters) harvested from carrier animal intramuscular tumors were injected supraselectively into an intralobar artery using fluoroscopically guided transcatheter ...

Rapid, Sequential Renal Blood Flow Scintiphotography
Radiology, 1969With the use of the Anger Scintillation Camera, the injection of a small bolus containing a large amount of radioactive tracer makes possible visualization of major vascular pathways as well as of the blood supply to certain critical organs, such as the kidney.

The microcirculation of the kidney is unique. Most organs are relatively homogeneously prefused by arteries and veins that are interconnected by a capillary bed that supplies oxygen and nutrients to the tissue. In contrast, the perfusion of the kidney is highly heterogeneous.

Methods of renal blood flow measurement
Urological Research, 1996Variations in regional renal blood flow have been implicated in a variety of disease states. Many techniques have been developed in an attempt to accurately assess these changes. The microsphere technique is the most widely used method at the present time.

Renal Blood Flow in Moderate Hypothermia
Archives of Surgery, 1960Although there is general agreement that renal blood flow is depressed by body cooling, there is some disagreement concerning the extent of this alteration. These discrepancies may be related to the wide variation in the degree of hypothermia induced1,6,7,10,11,15and, more particularly, to the methods for measuring renal blood flow.13Some evidence has ...

Regional Renal Blood Flow in Ewes
American Journal of Veterinary Research, 1981SUMMARY Regional blood flow to the kidneys was measured in 6 ewes by injecting carbonized microspheres (15 μm ± 5) labeled with 85Sr into the left ventricle. There was no significant (P > 0.25) difference in the mean arterial pressure before and after injection of the microspheres.

Renal Blood Flow during Acute Renal Failure in Man
Blood Purification, 2009<i>Background:</i>In the critically ill, ischemia secondary to decreased renal blood flow (RBF) is believed to be central to the pathogenesis of acute renal failure (ARF); however, the scientific basis for this conclusion has not been systematically evaluated.

Measurement of renal medullary blood flow
Experientia, 1969Toutes les methodes de determination du flux sanguin dans la medullaire renale sont basees, jusqu'a present, sur lemploi de substances traceuses. Les differentes techniques sont passees en revue dans le present artical. Quelques-unes manquent de fondation theoriques rigoureuse; cependant, les valeurs moyennes obtenues pour le temps de passage a travers
