Comparison between three mathematical models of KT/V.

In thirty anuric patients undergoing chronic hemodialysis the KT/V values obtained with the formula: (formula; see text) were compared with the values obtained with the following two formulae: (formula; see text) The results given by formulae B and C differed from those with formula A respectively by 12.81 +/- 11.98% and 10.38 +/- 3.64%. For routine determination of KT/V we suggest the use of formulae A and C as a means of establishing rapidly, in one step, whether the hemodialytic treatment examined is adequate.

The use of immobilized enzyme reactors in continuous-flow analyzers for the determination of glucose, urea, and uric acid.

We describe the use of immobilized enzymes in assay methods for the determination of glucose with glucose oxidase, uric acid with uricase, and urea with urease in serum samples. The enzyme reactor tubes were adapted to continuous-flow analyzers (Technicon AA II, SMA 12/60, and SMAC) used in routine laboratory determinations, and results with their use were compared to those from assays involving soluble enzymes. We substituted the reactors for the free enzyme reagents in the respective channels of the SMA 12/60 and SMAC, without modifying the parameters of the remaining channels. We compared assay sensitivity, precision, and carryover for immobilized and conventional liquid enzymes. Immobilized enzyme reactors provide accurate, reliable, convenient, and economical alternatives to the use of free enzyme reagents in these systems.

[Mass transfer of magnesium in hemodialysis].

The rate of mass-transfer (MT) of magnesium during hemodialysis was studied in thirty-five patients with hypermagnesemia (Mg = 3.75 +/- 0.72 mg/dl) undergoing chronic hemodialysis. The aim of the study was to verify which is the best dialytical approach to remove the excess of magnesium. The concentration of Mg in the dialysate was of 1.82 mg/dl for all patients. MT was -0.51 +/- 0.36 g and no statistical difference was found between patients treated with cuprophan hollow fibers dialyzers, PAN and cuprophan plates. Mg MT is not correlated with dialysis duration (r = -0.23; p:ns), urea clearance (r = -0.08; p:ns), KT/V index (r = -0.03; p:ns), blood flow (r = -0.15; p:ns). In conclusion from our data, in agreement with other Authors, reduction of serum Mg levels is more convenient by obtained by a decrease in Mg concentration in the dialysate under 1.82 mg/dl, in order to increase the blood-dialysate concentration gradient.
