Quality Test of Buformin and Urinary Excretion in Man

Excretion of Urinary Kinin in Man.

In 1952, Beraldo1) discovered an active polypeptide in dog urine, and designated it Substance U. Two years later, Werle and Erdos2) reported the presence of similar principle in human urine under the name of Substance Z. Thereafter, the urinary substance has been investigated by several authors3-8) to characterize its pharmacological and biochemical properties. It has been found by these invest...

Urinary Excretion and Serum Concentration of Inorganic Phosphate in Man.

Urinary oxalate excretion during intravenous infusion of diuretics in man.

Factors influencing the urinary excretion of free catecholamines in man.

1. The 24 h urinary excretion of noradrenaline and adrenaline is significantly lower in recumbent than ambulant normal subjects. 2. A diurnal variation exists in catecholamine excretion, the lowest values occurring during sleep. 3. Diurnal variation in sodium excretion parallels that in noradrenaline and adrenaline loss but the cycles can be separated by acute alterations in sleep/awake pattern...

Silicic acid: its gastrointestinal uptake and urinary excretion in man and effects on aluminium excretion.

Silicon (Si), as silicic acid, is suggested to be the natural antidote to aluminium (Al) toxicity, and was recently shown to promote the urinary excretion of Al from body stores. The metabolism of Si in man, however, remains poorly investigated. Here we report on the pharmacokinetics and metabolism of Si in healthy volunteers following ingestion of orthosilicic acid (27-55 mg/l Si) in water. We...
