Ultrafiltration and high sodium concentration dialysis: pathophysiological correlation.

Five stabilised uraemic patients underwent two different procedures using the Gambro Ultradiffuser: ultrafiltration alone for one hour (mean body weight loss 2.97 +/- 0.24 kg) and ultrafiltration with simultaneous dialysis for one hour (mean body weight loss 2.92 +/- 0.22 kg) using a given dialysate sodium concentration which reproduced the changes in osmolality which occur during ultrafiltration alone. This mean sodium concentration was 154.75 +/- 2.02 mEq/L. The results did not show significant differences for the two procedures as regards tolerance to dehydration. These results underline the key role of osmolar stability in making dehydration tolerable.

[Relationship between rhodamine 6G accumulation and fluconazole resistance in Saccharomyces cerevisiae S288c].

Severe mycotic infections are a source of concern in immunocompromised patients or in those who receive chemotherapy for hematological malignant diseases. One of the causes is referred to the appearance of antimycotic resistant microorganisms. Fluconazole is one of the antimycotic used for invasive mycoses treatment. Therefore it is necessary to evaluate the factors that originate this resistance. In the present report the yeast Saccharomyces cerevisiae S288c was used as a model system. In resistant strains the accumulation of the lipophilic cation Rhodamine 6G, L-leucine uptake and growth inhibition by crystal violet dye were determined. The results presented herein demonstrate the correlation between the membrane potential and the resistance to fluconazole presented by S. cerevisiae strain S288c.
