OBJECTIVE To investigate the effect of different sodium concentrations in replacement fluids on haematological variables and endurance performance during prolonged exercise. METHODS Thirteen female endurance athletes completed three four hour runs on a 400 m track. Environmental conditions differed between the three trials: 5.3 degrees C and snow (trial 1), 19.0 degrees C and sunny weather (t...

Thirty six male Chall lambs (four-month old and 26  ±1.5 kg body weight) were randomly assigned into four treatments (nine lambs per treatment) to study the effect of Powerfeed® (a commercial mixture made from wheat processing by-product and wheat bran) on weight gain, feed intake, feed conversion ratio, serum sodium and potassium concentration and urine pH. Lambs in control group were fed with...

OBJECTIVE Health logos are introduced to distinguish foods with 'healthier' nutrient composition from regular foods. In the present study, we evaluated the effects of changed food compositions according to health logo criteria on the intake of saturated fat, sugar and sodium in a Dutch population of young adults. DESIGN Foods in the Dutch food composition table were evaluated against nutrient...

INTRODUCTION Contrast-induced nephropathy is one of the main causes of acute kidney injury and increased hospital-acquired morbidity and mortality. The use of sodium bicarbonate for nephroprotection has emerged as a preventative strategy; however, its efficacy is controversial compared to other strategies, such as hydration using 0.9% saline solution. OBJECTIVE To compare the effectiveness of...

The use of sodium bicarbonate for nephroprotection has emerged as a preventative strategy; however, its efficacy is controversial compared to other strategies, such as hydration using 0.9% saline solution.

OBJECTIVE Significant and poorly documented electrolyte losses result from prolonged sweating. This study aimed to quantify likely sodium losses during work in heat. METHODS Male subjects exercised in an environmental chamber on two consecutive days in both winter and summer. Sweat collecting devices were attached to the upper arms and legs. RESULTS Sweat rates were higher and sodium concen...

The mechanisms underlying the acute antidiuretic response to bendroflumethiazide (BFTZ; 0.25 mg/h for 3 h) in rats with nephrogenic diabetes insipidus (NDI) was investigated. NDI was induced in conscious chronically instrumented female Wistar rats either by chronic lithium administration (40-60 mmol Li/kg of diet for 4 weeks) or by acute infusion of V2 antagonist OPC-31260 (0.2 mg/h). Renal cle...
