On the glomerular tubular balance in the rat kidney.

Abstract

1. The concept of glomerular tubular balance implies the constancy of fractional reabsorption of glomerular filtrate by the proximal convoluted tubules despite alterations in the arterial blood pressure or GFR. This concept was investigated in the kidney of the nondiuretic rat during acute alterations in arterial pressures from 50–160 mm Hg.
