Why the study?
Does efferent renal sympathetic nerve stimulation alter regional renal haemodynamics in Wistar rats?
Does efferent renal sympathetic nerve stimulation alter regional renal haemodynamics in Wistar rats?
Renal sympathetic nerve stimulation causes frequency-dependent vasoconstriction in the renal cortex and total renal blood flow, while medullary blood flow appears to be under strong local control that offsets neurogenic restrictions.
No takes yet. Share an insight, caveat, or question.
Renal sympathetic stimulation differentially vasoconstricts cortex while sparing medulla in rats; leaves open relevance to human renal denervation or hypertension therapies.
RUDENSTAM et al. (1995) studied this question.
