To study the effect of renal ischemia on the circulation in the inner medulla, blood flow in
descending and ascending vasa recta was determined by fluorescence videomicroscopy in …

Inner medullary blood flow has been found to remain nearly unchanged during postischemic
renal failure, despite a severely disturbed perfusion in the outer medulla. In order to …

Acute renal failure was induced in heparinized rats by clamping the renal artery for 45 min.
Ten minutes after recirculation the intrarenal blood flow distribution was measured. For this …

For the last 20 years ‚changes in renal cortical blood flow were thought to be of paramount
importance in the pathogenesis of acute renal failure. It was not until recently that a number …

We studied the responses of total renal blood flow (RBF) and renal medullary blood flow
(RMBF) to changes in renal perfusion pressure (RPP) within and below the range of renal …

Abstract Changes in medullary circulation may contribute significantly to the pathogenesis of
ischemic acute renal failure. The microcirculation of the outer medulla of the rat kidney was …

Thiel: For many years a reduction in total renal blood flow, which comprises mainly cortical
blood flow, has been considered to be an essential feature of acute renal failure. However, if …

Methods Experiments were performed on male, Sprague-Dawley rats (Charles River
Breeding Laboratory, Wilmington, MA), weighing 200 to 300 g. Two groups of animals were …

The effects of 2 hours of renal artery occlusion were studied in previously
uninephrectomized rabbits. Oliguric renal failure by arterial clamping was produced. Renal …

To test the thesis that ureteral obstruction causes medullary ischemia, we determined inner
medullary plasma flow (IMPF) in rats with bilateral or unilateral ureteral obstruction, and after …
