Abstract
Summary
After section of the left or right vagus nerve in two groups of dogs in mild water diuresis, triphasic responses in urine flow, free-water clearance, and osmolal U/P ratio occurred. However, significant quantitative differences in these responses for the two groups indicate a superior influence of the left vagus nerve on the mechanism controlling the renal reabsorption of solute-free water. During the various phases, glomerular filtration rate, effective renal plasma flow, or osmolal clearance did not change significantly from control values.
