[Sorption unit for regeneration of dialysis solution in artificial kidney].

The authors present the results of the tests of an adsorption unit model for a renal dialyzer comprising ligand-metabolic material. The solution is effectively purified of urine, ammonium, creatinine, uric acid, sulphates and phosphates. Hydrodynamic properties of the unit were investigated.

[Urea balance in the treatment of acute renal failure by hemofiltration].

Hemofiltration efficacy was assessed in 14 patients with acute renal insufficiency. Purification quality was controlled by the balance of urea as a marker of low molecular mass substances. Ten patients survived.

[Comparative evaluation of the effectiveness of plasmapheresis and lymphocytoplasmapheresis in the combined treatment of rheumatoid arthritis].

The authors compared 2 methods of apheresis: plasmapheresis (PA) and lymphocytoplasmapheresis (LPA) in 24 patients with rheumatoid arthritis (RA). Both methods were shown to produce a positive effect on a course of rheumatoid process decreasing clinical and laboratory parameters of its activity, improving articular function. Under LPA influence the production of autoantibodies by B-lymphocytes was significantly lowered.
