Smyth et al. examined the association between urinary sodium and potassium excretion and adverse renal outcomes in adults at high cardiovascular risk. They found no association between urinary sodium excretion and adverse renal outcomes, but a reduced odds of adverse renal outcomes with higher urinary potassium excretion. It will be important to ascertain whether this finding holds true in indi...

We examined sex differences in kidney mineral concentrations and urinary albumin excretion in rats given feed containing various phosphorus (P) levels. With feed that was 0.6%, 0.9%, 1.2%, and 1.5% P, kidney calcium and P concentrations were higher in female rats than in male rats. With 1.2% or 1.5% P, urinary albumin excretion was higher in the female rats. The sex of the animal affected the k...

BACKGROUND Phyllanthus amarus (Schum & Thonn), a plant belonging to the family of Euphorbiaceae is used in Ivorian traditional medicine to treat cardiovascular disorders such as hypertension. However, although this plant has been described as a diuretic agent, the underlying mechanism remains unclear. Therefore, the aim of the present study was to investigate the mechanism action of diuretic ef...

The results obtained in the present investigations point to a definite correlation between the onset of myocardial injury, electrocardiographic changes and biochemical changes. Changes in the electrocardiogram and elevated serum levels were paralleled by an increased excretion of magnesium in urine as early as one hour. Serum calcium and serum potassium levels did not show any significant ...

Background and Aims: Hypertyrosinemia type 3 (HT3) is an inherited error in tyrosine metabolism caused by a mutation in the 4-hydroxyphenylpyruvate dioxygenase (HPD) gene. Here we report a one and half-year-old girl infant who was diagnosed based on increased serum tyrosine levels and increased urinary excretion of p-hydroxyphenyl derivatives. Materials and Methods: The proband was one and ha...

INTRODUCTION Previous studies have demonstrated that the urinary excretion of angiotensinogen is significantly increased in ANG II-infused hypertensive rats, which is associated with an augmentation of intrarenal ANG II levels. These findings suggest that urinary angiotensinogen excretion rates provide an index of intrarenal ANG II levels in ANG II-dependent hypertensive states. However, little...

BACKGROUND Serum γ - glutamyltransferase (GGT) is implicated in the pathogenesis of endothelial dysfunction and atherosclerosis. Albuminuria is a marker of endothelial damage and correlated with structural and functional integrity of the vasculature. Our objective was to evaluate the association between serum GGT level and prevalence of albuminuria in a Chinese population. MATERIALS AND METHO...

Lithium therapy's most common side effects affecting the kidney are nephrogenic diabetes insipidus (NDI) and chronic kidney disease. Lithium may also induce a distal renal tubular acidosis. This study investigated the effect of chronic lithium exposure on renal acid-base homeostasis, with emphasis on ammonia and citrate excretion. We compared 11 individuals on long-term lithium therapy with six...
