PURPOSE We verify the sodium fraction excretion rate (FE Na) and potassium fraction excretion (FE K) rates in monosymptomatic nocturnal enuresis. We also correlate FE Na and FE K to urinary osmolality, nocturnal polyuria and vasopressin in the same population. MATERIALS AND METHODS A total of 438 children 6 to 15 years old (mean age 9.7) presenting with monosymptomatic nocturnal enuresis were...

The rate and cumulative volume of diuresis were measured sequentially for each incremental infusion dose of 5 ml/kg body weight till a 100 ml/kg or more dose was reached. Normal saline (NS), Ringer-Locke (RL) and tender coconut water (TCW) were infused in three groups each of paraldehyde (PLD), and chloralose and urethane (C & U) anaesthetised dogs. The slow infusion rate of about 0.5 ml/kg/min...

A B S T R A C T In the present studies, the effect of ampicillin (40 mg intramuscularly twice a day) in combination with water diuresis, produced by the ingestion of 5% dextrose in water, was determined on renal titers of enterococci after intravenous inoculation of 4 X 10'-2 X 109 enterococci into rats. Ampicillin injections with or without diuresis were started 4 or 21 days after initiation o...

Water diuresis has different effects on the outcome of urinary infections in rodents depending on the test organism, the route of inoculation, and the species of animal used. In rats, the production of pyelonephritis following hematogenous inoculation of Staphylococcus aureus, Candida albicans or Streptococcus fecaelis was prevented or cured by water diuresis."' The possible mechanisms by which...

With diabetes mellitus, the ability of the kidneys to maintain fluid balance is affected. Hyperglycaemia increases production of hyaluronan in cultured kidney cells implying that diabetes promotes induction of hyaluronan in the kidney. The aim of the present study was to determine if the interstitial matrix component hyaluronan is differently distributed within the kidney in diabetic rats compa...

The hypertonicity of interstitial fluids of renal medulla and papilla, present during antidiuresis, is reduced during water diuresis. This is the result of a decrease in the absolute amount of sodium in the medulla and papilla as well as dilution by an increase in the tissue content of water."2 It is not clear whether the decrease in tissue content of sodium which accompanies water diuresis is ...

DELL, RALPH B., AND ROBERT W. WINTERS. Lactate gradients in the kidney of the dog. Am. J. Physiol. 2 I 3(2) : 301-307. r g67.Previous studies have shown that the inner medulla of the antidiuretic kidney has a higher concentration of lactate than the renal cortex, blood, or urine and that medullary lactate rises even higher during osmotic diuresis. The present study was designed to ascertain whe...

It has recently been shown that the diuresis of fed 5th-stage larvae of Rhodnius is brought about by a hormone that appears in the haemolymph (Maddrell, 1962, 1963). This diuretic hormone is released from the fused ganglionic mass in the mesothorax, probably from its posterior neurosecretory cells. This paper examines some of the features of this diuresis in the light of this discovery and incl...

The mechanism of ascites formation has been a subject of interest for many years and remains a challenge to the investigator. In previous reports (1, 2) on 61 patients with cirrhosis of the liver, it was pointed out that those with ascites have lower values for serum albumin than do those without ascites and that the tendency to diuresis (and the loss of ascites) was correlated with a rise of t...
