THE NUMERICAL SOLUTION OF THE TIME-DEPENDENT NERNST-PLANCK EQUATIONS.

Calculations are reported of the time-dependent Nernst-Planck equations for a thin permeable membrane between electrolytic solutions. Charge neutrality is assumed for the time-dependent case. The response of such a membrane system to step current input is measured in terms of the time and space changes in concentration, electrical potential, and effective conductance. The report also includes discussion of boundary effects that occur when charge neutrality does not hold in the steady-state case.

A clinical evaluation of peritoneal dialysis.

A total of 18 peritoneal dialyses were performed on 14 patients at the Hamilton Civic Hospital over a period of 11 months. Nine of these patients were in uremia, four had non-nephrotoxic intoxication, and one had hepatic coma. Patients with chronic uremia may present with acute renal failure which may be treated by peritoneal dialysis with resultant significant prolongation of life. A decreased mortality rate might be expected in acute renal failure if dialysis is implemented before the classical picture of uremia develops. Many non-nephrotoxic intoxicating substances are readily dialysable. Considerable benefit to the patient and decreased time in hospital may result from the use of this procedure in cases of intoxication with such substances. Peritoneal dialysis may be of value in treatment of intractable congestive heart failure. This procedure may eventually provide another means of treating hepatic coma.
