Effect of Elevation of Intraluminal Pressure on Renal Vascular Resistance

Abstract

Elevation of renal venous pressure in pentobarbitalized laparotomized dogs elicits renal vascular constriction. Part of the vasoconstriction appears to be dependent upon a venous-arteriolar reflex. The reflex pathway is not distributed locally. A portion of the vasoconstriction is dependent upon still unrecognized local factors.
