The nature of brain edema in dialysis disequilibrium syndrome (DDS) was investigated by diffusion-weighted magnetic resonance imaging (DWI). DWI was performed on normal or bilaterally nephrectomized rats before, and immediately after, hemodialysis. Hemodialysis was performed with a custom-made dialyzer (surface area 150 cm2) against a bicarbonate-buffered bath for 90 min with or without 70 mM u...

Some plant extracts showed the ability to retard the diffusion of glucose across the dialysis tube. The present study was designed to investigate the effect of aqueous and ethanolic extracts of Teucrium polium (T. polium) on glucose movement across the dialysis tube. The T. polium powder was dissolved in ethanol and distilled water. Then glucose was added to make a final concentration of 0.2 - ...

BACKGROUND Chronic inflammation in haemodialysis (HD) patients indicates a poor prognosis. However, therapeutic approaches are limited. Hydrogen gas (H(2)) ameliorates oxidative and inflammatory injuries to organs in animal models. We developed an HD system using a dialysis solution with high levels of dissolved H(2) and examined the clinical effects. METHODS Dialysis solution with H(2) (aver...

1. Free amino acids were determined in the plasma and in the muscle tissue of 14 patients with chronic uraemia; eight were not on dialysis and six were having regular peritoneal dialysis. The concentration of each amino acid in muscle water was calculated with the chloride method. 2. In both groups of patients there were low intracellular concentrations of threonine, valine, tyrosine and carnos...

Understanding the means of acquisition, sources, and reservoirs of nosocomial pathogens is crucial for developing methods to reduce the incidence of nosocomial infections. The article in this issue by Graman et al1 highlights the continued importance of the environment, especially water sources, as a reservoir for nosocomial pathogens. Important water reservoirs in the hospital include potable ...

According to the present extent of our knowledge it appears that the pressor and the antidiuretic activities of Pitressin 1 both reside in the same substance. Since Kamm (1) showed that the pressor activity dialyzes from aqueous solution, the antidiuretic activity should dialyze also. But Ralli (2) found that when Pitressin mixed with normal urine was dialyzed against water the full antidiureti...

background protein-bound toxins such as indoxyl sulfate (is) are not efficiently removed by conventional hemodialysis (hd). objectives to improve the removal of is, we performed an in vitro study to evaluate the effects of high dissolved hydrogen on the dissociation of is from albumin using simulated hd. materials and methods wasted dialysate from peritoneal dialysis was concentrated a hundred ...

BACKGROUND Water treatment systems are a critical variable in dialysis therapy. Rigorous control of hemodialysis water quality is particularly important in order to guarantee a better quality of life of the hemodialysis patients. The objective of the study was to evaluate the chemical, microbiological quality and antimicrobial resistance of bacteria isolated from water and dialysate in a public...
