Effect of renal nerve stimulation on NaCl and H2O transport in Henle's loop of the rat

DiBona, G. F., Sawin, L. L.·1982·American Journal of Physiology-Renal Physiology

Abstract

To assess the effect of renal nerve stimulation on sodium, chloride, and water transport in the loop of Henle, experiments were performed in anesthetized hydropenic and isotonic saline volume-expanded rats using renal clearance and Henle's loop microperfusion techniques (end-proximal convoluted tubule perfusion site, early distal convoluted tubule collection site). As compared with the control period values, low-frequency (less than 1.0 Hz) renal nerve stimulation decreased absolute and fractional urinary flow rate and sodium and chloride excretion without affecting mean arterial pressure, glomerular filtration rate, renal blood flow, or renal vascular resistance. In the loop of Henle, the absorptive transport of water was not affected, whereas the absorptive transport of sodium and chloride was increased in both hydropenic (Na 111 +/- 49 peq/min) and isotonic saline volume-expanded rats (Na 154 +/- 69 peq/min, Cl 180 +/- 52 peq/min) during low-frequency renal nerve stimulation. Low-frequency renal nerve stimulation decreases urinary sodium and chloride excretion via a direct effect of increasing renal tubular sodium and chloride reabsorption. In addition to the established effect of increasing proximal tubular sodium reabsorption, Henle's loop sodium and chloride absorption are also increased, supporting a physiological role for the adrenergic innervation of these structures.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
