Outpatient evaluation of dietary intake and nitrogen removal in continuous ambulatory peritoneal dialysis.

Five patients on continuous ambulatory peritoneal dialysis were studied to evaluate dietary intake, glucose absorption from the dialysate, and urinary and dialysate nitrogen removal. The study was done on an outpatient basis, while the patients ingested their usual diets and went about their usual activities. The results indicate that patients greatly overestimated their caloric and protein intake, which was 0.

Filtration of protein in the anti-glomerular basement membrane nephritic rat: a micropuncture study.

Production on an anti-glomerular basement membrane (anti-GBM) nephritis in the rat results in a 30-fold increase in glomerular membrane permeability to albumin. The concentration of albumin in glomerular filtrate, estimated from proximal tubular fluid samples, is ten times the normal value. Tubular reabsorption of albumin is not enhanced so that essentially the filtered load is excreted.

Investigations on pituitary and Leydig cell function in chronic hemodialysis and after renal transplantation.

The hypothalamus-pituitary-Leydig cell axis was investigated in 20 male patients undergoing intermittent hemodialysis and in 21 male patients following renal transplantation compared to normal controls. Plasma testosterone as well as luteinizing hormone and follicle stimulating hormone were determined by radioimmunoassay under basal conditions and after stimulation with choriongonadotropic hormone and hypothalamus releasing hormone respectively. Suppressed Leydig cell function has been demonstrated in dialysed patients as well as in patients after renal transplantation.
