Oxalate Balance in Peritoneal Dialysis Patients: A Potential Role of Dialysis-related Peritonitis.

Background: Little evidence is available on oxalate balance in peritoneal dialysis (PD) patients.

Patients And Methods: We performed a cross-sectional observational pilot study with 62 adult PD patients to document oxalate balance and explore its association with PD-related peritonitis. Plasma oxalate concentration, levels of oxalate excretion in 24-h urine, and peritoneal dialysis effluent were evaluated.

[Kinetic analysis of induced platelet aggregation].

Two mathematic models depicting the kinetics of induced platelet aggregation are suggested. The mechanisms of platelet aggregation involving the reactions of the inductor molecules with membrane receptors and intercellular interactions of platelets are discussed. Analytical expressions depicting the changes in the amount of platelets in the aggregation population and in the course of aggregation are offered.
