[New data on characteristics of the chemism of erythrocytes in patients with metabolic-alimentary obesity].

A study was made of the erythrocytic membranes in patients with stage II-III metabolic and alimentary obesity. The red blood cells may serve as model of the membranes of other cells of the internal organs, that is why their changes are likely to mirror the total impairment of the function of the cell membranes in the illness under consideration. The patients' red blood cells were characterized by high permeability, increased ATPase activity, catalase activation, reduction of the content of the thiol groups, and by the displacement of the thiol-disulfide balance towards oxidized forms.

[Programmed fluid removal during hemodialysis in patients with unstable hemodynamics].

In 7 anuric patients with chronic renal failure treated by hemodialysis for a period from 36 up to 73 months a programmed drawing out of fluids was applied by using a dialyzing solution with variable sodium concentration in order to avoid heavy hypotensive incidents. The concentrations of potassium, sodium in serum and erythrocytes, plasma osmolarity, arterial pressure, body mass, use of medicaments were examined. The "programmed dialysis" led to a greater with 1.

[Clinical testing of the Bulgarian Diamex dialyzers].

The Bulgarian dialyzers "Diamex" were clinically tried as well as original patterns of the firm Fresenius--"Hemaflow" in 28 patients from the Centre of hemodialysis at the Medical academy. The results obtained for the clearances of Bulgarian dialyzers (urea clearance--2.61 ml/s, creatinine clearance--2.
