Abstract Guanidine (G), 1-methylguanidine (MG), and 1,1-dimethylguanidine (DMG) have long been implicated as uremic "toxins." A method has been developed for determining G, MG, and DMG in serum and urine. Specimens were chromatographed on carboxylate resin, with use of 1 molar NaOH, and quantitated colorimetrically with a modification of the Voges— Proskauer reaction. The mean values for G and MG in the serum of uremic patients were 0.3 and 0.4 mg per liter, respectively. DMG was not detected. Although the urinary excretion of MG is significantly increased in renal failure, the concentrations of G, MG, and DMG in serum are not markedly increased, and it is therefore unlikely that G, MG, or DMG contribute to the toxic manifestations of the uremic syndrome.

1. Urinary clearance of antidiuretic hormone (ADH) has been measured under basal conditions and during intravenous administration of arginine vasopressin in ten healthy subjects, and only under basal conditions in 18 patients with chronic renal failure and seven patients with acute renal failure at the polyuric phase of the disease. 2. In healthy subjects studied under conditions of mild water diuresis, plasma concentration, urinary excretion rate, urinary clearance and fractional clearance of ADH were 3.3 ± 0.36 pg/ml, 25.2 ± 5.5 pg/min, 7.5 ± 1.2 ml/min and 6.4 ± 1.0% (means ± sem) respectively. When plasma ADH was raised to levels between 7 and 26 pg/ml during intravenous administration of the hormone, urinary excretion rate and urinary clearance of ADH increased. Tubular reabsorption of ADH did not reach a plateau but progressively increased in the range of plasma ADH studied. 3. In patients with chronic renal failure, plasma concentration, urinary excretion rate, urinary clearance and fractional clearance of ADH were 2.8 ± 0.19 pg/ml, 9.4 ± 2.0 pg/min, 3.4 ± 0.6 ml/min and 10.0 ± 2.9% (means ± sem) respectively. Urinary excretion rate and urinary clearance were significantly lower than in healthy subjects. 4. In patients with acute renal failure, plasma concentration, urinary excretion rate, urinary clearance and fractional clearance of ADH were 4.6 ± 0.47 pg/ml, 52.8 ± 15.8 pg/min, 9.5 ± 2.7 ml/min and 24.9 ± 4.4% (means ± sem) respectively. Urinary excretion rate and fractional clearance were higher than in healthy subjects and patients with chronic renal failure. 5. These results demonstrate that most of the filtered ADH is reabsorbed by the tubules. The reabsorptive capability is markedly diminished in patients with acute renal failure at the polyuric phase of the disease.

Base Balance

The effect of a meat load on the renal handling of acid-base balance was studied in ten healthy subjects (GFR by inulin clearance = 98.5 +/- 8.14 ml.min-1.1.73 m-2) and in ten patients affected by chronic renal failure (CRF) (GFR = 39.9 +/- 5.3 ml.min-1.1.73 m-2). After the meat load (2 g.kg-1 body weight of cooked unsalted red meat), GFR increased by 26.9% (peak value) over baseline in healthy subjects and by 32% in CRF patients. The acid-base status of the healthy subjects was in the normal range, whereas the CRF patients disclosed a slight metabolic acidosis. After a meat load, there was, in the healthy subjects, an increase in the filtered load of bicarbonate coupled to an enhanced tubular reabsorption and urinary excretion. The time course between bicarbonate load and urinary excretion was coincident. In CRF patients, the increase of bicarbonate tubular load after the meal was associated with an increase in tubular reabsorption but not in urinary excretion of this anion. The relationship between bicarbonate load and reabsorption was linear in both groups up to the highest filtered loads. Baseline titratable acidity (TA) and ammonium (NH4+) excretion (expressed per ml GFR) were increased in CRF patients as compared with control subjects, but no changes were found after the meat load in both groups in these experimental conditions. The data indicate that the renal tubules contribute to the maintenance of acid-base balance both in healthy subjects and in CRF patients by reabsorbing most of the additional bicarbonate load. The transient, but significant, increase in bicarbonate excretion observed in healthy subjects could be related to the increased tubular load of bicarbonate. In CRF patients, tubular bicarbonate reabsorption was more complete, possibly because of the stimulation of H+ secretion by the mild metabolic acidosis. TA and NH4+ did not participate in tubular compensation of the increased buffer load.
