[Ultraviolet spectrophotomerty studies of serum dialysate from patients with long term intermittent artificial kidney treatment].

In 16 chronically dialysed uraemic patients in the course of altogether 61 treatments with the artificial kidney the UV-absorption spectre of the in-vitro-dialysate of the serum was studied. In uraemia on account of the retention of the metabolic products the UV-absorption spectre of the serum dialysate is extremely increased, a decrease is to be registered after the dialysis. The method discussed is suitable for the control of the effectiveness of haemodialysis and gives a more complex picture concerning the changes during the treatment than the usual laboratory parameters.
