The influence of dialysis fluid composition on the blood pressure response during dialysis.

To elucidate the relative role of osmolar (sodium) and acetate shifts during dialysis, 6 patients with problems of overhydration underwent rapid ultrafiltration for 1 hr (mean weight reduction 2.0 kg), using the 1 m2 RP 6 dialyzer. Ultrafiltration was carried out at the beginning of each of 5 dialysis treatments at weekly intervals. Ultrafiltration was undertaken without dialysis (controls) and with simultaneous dialysis using acetate (40 mmoles/1) or bicarbonate (25 mmoles/1) in the dialysis fluid with dialyzate sodium concentration of 133 and 145 mmoles/1. The systolic blood pressure and mean arterial pressure which were stable with ultrafiltration only fell slightly when a high dialyzate sodium concentration was used and much further when the dialyzate sodium concentration was kept low. These changes were apparently related to the changes in plasma osmolality. Acetate had no effect on blood pressure at the higher sodium concentration, but a slight (insignificant) additive effect when used in the low-sodium dialyzate. Shifts in osmolality (sodium concentration) seem to be more important than the effect of acetate in inducing dialysis-associated hypotension.

The effect of renal transplantation on middle molecules in plasma and urine.

The plasma level and urinary excretion of middle molecules were determined in 5 patients with chronic uremia undergoing renal transplantation. The results demonstrate that after successful transplantation, the uremic middle molecules disappear rapidly from plasma while being excreted in the urine. The reduction in plasma level of middle molecules after transplantation is more rapid than the reduction in creatinine concentration.

Hypersequestration of 51Cr-labelled erythrocytes as a criterion for splenectomy in regular hemodialysis patients.

The splenic uptake of 51Cr-labelled autologous erythrocytes was studied by body surface counting in 20 hemodialysis patients. Evidence for splenic hypersequestration of erythrocytes was obtained in 7 patients. Splenectomy was performed in 6 of these and led to a reduction in transfusion requirements. One patient without evidence of splenic hypersequestration of red cells was also subjected to splenectomy but was not improved. The importance of following the splenic uptake of 51Cr for a sufficiently long time to detect a delayed uptake of 51Cr is pointed out.

Lack of point mutation of the APP gene in sporadic Alzheimer's disease in Japanese.

We investigated point mutations of the APP gene in 66 patients with sporadic Alzheimer's disease (AD) and 180 normal individuals by use of the PCR (polymerase chain reaction) method. Both the AD patients and the normal individuals were Japanese. We extracted DNA from blood samples using the phenol-chloroform method and amplified exons 16 and 17 of the APP gene by PCR. PCR products were digested by MBO-II (exon 16) and BCL-1(exon 17). Electrophoresis was carried out with 3% agarose gel and the separated fragments were stained with ethidium bromide. In addition we investigated other point mutations of exons 16 and 17 by use of the PCR-SSCP (single stranded conformation polymorphisms) method, and found no fragments that exhibited point mutations in the AD patients and normal individuals. These findings indicate that the presence of point mutation of the APP gene is not a major cause of AD in the Japanese population.
