BACKGROUND Urological complications associated with sickle cell disease (SCD), include nocturia, enuresis, urinary infections and urinary incontinence. However, scientific evidence to ascertain the underlying cause of the lower urinary tract symptoms in SCD is lacking. OBJECTIVE Thus, the aim of this study was to evaluate urinary function, in vivo and ex vivo, in the Berkeley SCD murine model...

BACKGROUND Adenosine A(1) receptor blockade has been suggested as a treatment in conditions with sodium and fluid retention because it increases urinary Na(+) excretion and increases proximal tubular fluid output. In the present study, we examine the time course for the renal responses to adenosine A(1) receptor blockade in order to investigate whether the effects may be prolonged and not just ...

Dogs with sustained anemia and hypoproteinemia due to bleeding and a continuing low protein or protein-free diet with abundant iron will continue to produce much new hemoglobin and plasma protein for many weeks. The stimulus of double depletion (anemia and hypoproteinemia) leads to raiding of body and tissue protein to fill the demand for new hemoglobin and plasma protein. The blood proteins in...

The author first reviews, on the basis of personal and literature data, the main changes in three major parameters of potassium metabolism: serum potassium; daily urinary output ofpotassium; exchangeable potassium (Ke) at the three stages of the course of liver cirrhosis. The action of K-sparing diuretics (spironolactone, triamterene, amiloride) on these parameters is analysed. Although the int...

We read with interest the recent article by Dr Chawla and colleagues showing that a furosemide stress test was able to predict the development of renal damage stage III according to the Acute Kidney Injury Network classification in critically ill patients [1]. In this study, 25 patients that subsequently developed acute kidney injury (AKI) had lower urine output 2 hours following administration...

The metabolic effects of oral ingestion of minute quantities of carbohydrate during prolonged starvation were studied in nine obese subjects. Measurements were made during a control period of total starvation, during the ingestion of 7.5 g carbohydrate daily, and finally during the ingestion of 15.0 g carbohydrate daily. Daily ketoacid excretion fell after carbohydrate ingestion and was signifi...

This is a longitudinal study of the daily urinary output and the concentrations in whole blood of cobalt and chromium in patients with metal-on-metal resurfacings over a period of four years. Twelve-hour urine collections and whole blood specimens were collected before and periodically after a Birmingham hip resurfacing in 26 patients. All ion analyses were carried out using a high-resolution i...

BACKGROUND Because hyperinsulinemia acutely stimulates adrenergic activity, it has been postulated that chronic hyperinsulinemia may lead to enhanced sympathetic tone and cardiovascular risk. METHODS AND RESULTS In 21 obese (body mass index, 35+/-1 kg/m(2)) and 17 lean subjects, we measured resting cardiac output (by 2-dimensional echocardiography), plasma concentrations and timed (diurnal ve...

SYMX~mO-AVmNAL ~mVULLAaY ACTXVrrY during anaesthesia has been studied fluorometrically, measuring catechol amines in peripheral and adrenal vein blood. 1-u Results of these studies indicated that light anaesthesia did not produce any signi~cant rise in catechol amines, whereas deeper planes of anaesthesia employing ether, cydopropane, chloroform, and vinyl ether produced significant increases i...

Hypothermia is a common complication in patients with extensive burns, receiving massive volumes of fluid for resuscitation at ambient temperature. It is therefore important to maintain the body temperature of patients with extensive burns. The present study was performed to evaluate the usefulness of warm fluid for burn injury resuscitation. Ten dogs were used in this study. Full-thickness bur...
