Biofiltration with bicarbonate as dialysate buffer.

The biofiltration with bicarbonate as dialysate buffer (BiBF) was used in 10 patients on RDT: the patients were treated for 10 months on standard BF and for 10 months on BiBF. The amount of fluid infused varied between 3 and 5 liters and Na-bicarbonate (100 mEq/h) was infused during BF. The dialytic protocol was 3 hours every other day.

Muzolimine in advanced chronic renal failure.

27 patients with creatinine clearances ranging from 20 to 2 ml/min were treated daily with 6.9 mg/kg of muzolimine, for 10 to 25 days. The hyperhydration state with oedema decreased gradually in all patients without hypotensive phenomena.

Favourable effects of bicarbonate dialysis on the body pool of phosphate.

An intravenous infusion of 3,430mg of PO4- has been given to 11 patients on acetate and to 11 patients on bicarbonate haemodialysis. The 'phosphate spaces' and dialytic removal were determined. The bicarbonate dialysis causes lower values of phosphate pool, total phosphate space, cellular space and phosphate cellular clearance.
