    Notes: : We investigated the effect of a commercial plant extract, Rosmol-P (RP) on the stability of fish during frozen storage. Horse mackerel (Trachurus trachurus) fillets were soaked in water (water control) and 2 RP concentrations (RP-1 = 0.333%; RP-2 = 1.333%) and compared with untreated fillets (blank control). Fluorescence detection and thiobarbituric acid index showed a lower oxidation development for both RP treatments than for both controls, especially in the case of the highest concentration (RP-2). The decrease in glutathione peroxi-dase activity was found to be slower in the case of the RP-2 treatment. The sensory analysis showed an increased shelf-life according to the sequence blank control 〈 water control 〉 RP-1, RP-2.

    Description / Table of Contents: Zusammenfassung Bei 70 fettsüchtigen Personen (26 Männer, 44 Frauen) wurden im Blutserum einige Lipidkomponenten und der Gehalt an Malondialdehyd (MDA) vor ihrer Abmagerungskur bestimmt. Aufgrund der klinischen Laborbefunde waren diese Patienten bei der Gruppe der Personen mit Hyperlipo-proteinämie einzuordnen (Einteilung nach Fredricksson und Lees). Bei 32 Personen war der Blutcholesteringehalt hoch (über 5,7 mmol/1), es bestand eine negative Korrelation zwischen MDA und hochdichten Lipoproteinfraktionen (HDL). Der größte Korrelationskoeffizient wurde in der Gruppe II/a bei Hyper-lipoproteinämie festgestellt (HDL-C, r=−0,74; HDL-2-C, r=−0,54; HDL-3-C, r=−0,78). Bei Personen mit normalem Serumcholesteringehalt konnte keine Korrelation nachgewiesen werden. Die Ergebnisse werden mit den durch Lipidperoxidation oxidierten Cholesterin-derivaten, welche die HDL-Synthese mindern, erklärt. Es scheint, daß bei Hyper-cholesterinämie der Fettsüchtigen die Lipidperoxidation beim Rückgang des HDL-Wertes eine bedeutende Rolle spielt und damit also einen wichtigen Schutz gegen kardiovaskuläre Erkrankungen bildet.
    Notes: Summary In the blood sera of 70 obese persons (26 men, 44 women) some lipid components and malondialdehyde (MDA) level were determined before slimming. The people were classified into groups of hyperlipoproteinaemia on the basis of laboratory results, according to Fredrickson and Lees. In 32 people with high blood cholesterol level (above 5.7 mmol) there were negative correlations between MDA and high-density lipoprotein (HDL) fractions. Correlation coefficients were the greatest in the group IIa of hyperlipoproteinaemia (HDL-C. r=−0.74; HDL-2-C. r=−0.54; HDL-3-C. r=−0.78). Correlations were not found in subjects with a normal cholesterol level. The results were attributed to the formation of oxidized cholesterol products, caused by lipid peroxidation, which may decrease the HDL synthesis. It seems that in hypercholesterolaemia coupled with obesity, lipid peroxidation can contribute to the reduction in HDL levels, which is an important protective factor against cardiovascular diseases.

    Description / Table of Contents: Zusammenfassung Es wurden vor und nach einer 7tägigen Entfettungskur (2,1 MJ/Tag) von 54 Fettsüchtigen stammende Blutproben auf einige Lipidkomponenten (Malondialdehyd [MDA] und die Aktivität der vor freien Radikalen schützenden Enzyme Superoxid-Dismutase [SOD] und Glutathionperoxidase [GSHpx]) untersucht. Nach 7tägiger Krankenhausbehandlung wurde eine Erniedrigung des Körpergeichts, der Triglyceride, des HDL-Cholesterin- und des HDL-3-Cholesterins sowie eine Zunahme von Gesamtcholesterin festgestellt. Nach einer zu Hause fortgesetzten drei Monate dauernden Kur (5,0–6,3 MJ) wurde eine Zunahme von HDL-2-Cholesterin und ein Rückgang von Gesamtcholesterin auf den Ausgangswert beobachtet. Bei an Hyperlipoproteinämie leidenden Vpn. und auch bei denen, die einen erhöhten Cholesterin- und Triglyceridgehalt aufwiesen, wurde eine höhere MDA-Konzentration festgestellt. Nach der Entfettungskur, unabhängig von den Lipiden, fällt die SOD-Aktivität. Die GSHpx-Aktivität ist unverändert, ausgenommen bei Männern mit hohem Cholesterinniveau. Weitere Untersuchungen über die vor freien Radikalen schützenden Enzyme sind erforderlich.
    Notes: Summary In blood samples of 54 obese persons (13 men, 41 women) some lipid components, malondialdehyde (MDA), and the activities of free radical protecting enzymes superoxide-dismutase (SOD) and glutathione-peroxidase (GSHpx), were determined before and after a seven-day slimming diet of 2.1 MJ/day. Body weight, triglycerides, HDL-cholesterol, and HDL-3-cholesterol all decreased, total cholesterol increased after the seven days hospitalization. After continuing the slimming diet (5.0–6.3 MJ/day) at home, HDL-2-cholesterol increased and total cholesterol returned to the initial value after three months. MDA decreased in the groups of hyperlipoproteinemia II/a and II/b and also in the group with high cholesterol and triglyceride levels (above 5.7 and 2.7 mmol/l). Correlation coefficients refer to the dominant role of high TG in the intensity of lipid peroxidation. The activity of SOD fell after the slimming, independent of lipid parameters. GSHpx activity remained unchanged except a drop in the male participants having high cholesterol levels. The behavior of the free radical protecting enzymes needs further examination.
