title: Renal tubular sodium reabsorption during the recovery from the oliguric phase of acute nephritis.
abstract: The urinary excretion of sodium, calcium, phosphorus and the reabsorption of solute free-water, were studied in seven water-restricted patients with post-streptococcal acute glomerulonephritis. During the recovery from the initial salt-retaining phase, there was a progressive increase in the urinary excretion of sodium, phosphorus and calcium either in absolute values or when expressed as their tubular rejection fractions. A progressive increase in free-water reabsorption as percentage of creatinine clearance was also demonstrated. The data suggest that in this phase of the disease there occurs a non specific supression of proximal tubular activity.
