Potassium has long been known to be almost completely confined to the intracellular compartment, and the neutral fat present in muscle has been shown to have a low chloride content (1). It seemed probable, therefore, that the error associated with predictions of total exchangeable electrolyte from total body weight would diminish if the variable of depot fat was eliminated by the use of lean bo...

In a randomized, double-blind study, we administered placebo and diclofenac sodium 100 mg suppositories 1 h pre-operatively and on the first post-operative morning to 22 adult patients undergoing minor orthopaedic surgery. A standardized post-operative intravenous fluid regimen was instituted until oral fluids were tolerated. Renal function was assessed pre-operatively, and on the first and sec...

The urinary excretion of cyclic adenosine 3',5'-monophosphate (cAMP), corrected for urinary creatinine, was determined in 177 patients with primary or metastatic tumours and in 149 normal subjects. In 26 patients with malignancy and in 10 control subjects the excretion of cyclic guanosine 3',5'-monophosphate (cGMP) was also evaluated. The urinary cAMP/Cr ratio in human neoplasms of epithelial o...

BACKGROUND Hypertension is the leading cause for heart disease and stroke, for mortality and morbidity worldwide, and a high sodium-to-potassium intake ratio is considered a stronger risk factor for hypertension than sodium alone. OBJECTIVE This study aims to evaluate sodium and potassium urinary excretion, and assess the food sources of these nutrients in a sample of Portuguese adolescents. ...

Background and Aims: Post exercise proteinuria and increased urinary Gamma-Glutamyl transferase (GGT) levels can be indicative of exercise-induced renal damage. The aim of this investigation was to study the effect of one session of intensive training on renal tubular injury markers and compare their values to those 6 hours after training, for evaluating tubular damage after intensive ...
