Východisko.
Oxidativní modifikace lipoproteinů, zvl. LDL, je považována za klíčový krok v rozvoji časnéaterosklerotické léze. Náchylnost lipoproteinů k oxidaci (oxidabilita) určuje jejich aterogenní potenciál. Sníženáodolnost LDL vůči oxidaci je pozorována např. u pacientů s hyperlipoproteinémií, hypertenzí a diabetes mellitus.Některé práce ukazují na možnost příznivého ovlivnění oxidability lipoproteinů hypolipidemickou léčbou.Metody a výsledky. 17 osob s primární hypercholesterolémií (fenotyp IIA/IIB) bylo po dobu 6 týdnů léčenopreparátem pravastatin (20 mg/den). Před nasazením a po skončení léčby byly stanoveny koncentrace plazmatickýchlipidů a lipoproteinů a zjištěny parametry lipoperoxidace lipoproteinů LDL hodnocené modifikovanou metodoustanovení kinetiky konjugovaných dienů LDL podle Esterbauera.

Overview
Background.
Oxidative modification of lipoproteins, in particular LDL, is considered a crucial step in thedevelopment of early atherosclerotic lesions. The oxidability of lipoproteins determines their atherogenic potential.A reduced resistance of LDL to oxidation is observed e.g. in patients with hyperlipoproteinaemia, hypertension anddiabetes mellitus. Some work indicates the possibility to influence the oxidability of lipoproteins in a favourableway by hypolipidaemic treatment.Methods and Results. 17 subjects with primary hypercholesterolaemia (phenotype IIA/IIB) was treated for sixweeks with pravastin (20 mg/day). Before onset and after termination of treatment concentrations of plasma lipidsand lipoproteins were assessed and parameters of lipid peroxidation of LDL lipoproteins evaluated by a modifiedmethod of assessment of conjugated LDL dienes according to Esterbauer. Treatment had a favourable effect on thelipid and lipoprotein profile (decline of total cholesterol by 24%, P
