[Value of plasma fructosamine in non-diabetic and diabetic chronic renal failure].

Plasma fructosamine concentrations were measured in non-diabetic and diabetic patients with chronic renal failure divided into two three groups: patients without dialysis, under haemodialysis and under continuous ambulatory peritoneal dialysis. In non-diabetic patients plasma fructosamine values were consistently higher than in a control population (2.26 +/- 0.

[Serum zinc and copper in hypercholesterolemia].

For some authors, absolute or relative copper deficiency, with an elevated plasmatic zinc/copper ratio, could be a risk factor in the etiology of cardiovascular diseases by altering lipid metabolism. Animal or human studies carried out with zinc and/or copper supplemented or deficient diets on biochemical lipid parameters, led to inconsistent results. Nevertheless, no study was already done in hypercholesterolemic patients, concerning possible correlation between serum levels of these trace elements and cholesterol, HDL cholesterol and apolipoprotein B blood levels.
