The effects of vegetable oils („non-erucic-acid” rapeseed oil and sunflower oil) and animal fat (butter) on the development of experimental atherosclerosis were studied in rabbits kept during 12 weeks on a cholesterol-rich diet. The degree of atherosclerotic changes by calculating planimetrically the site of the areas of fatty infiltrations in the aorta, the concentrations of total cholesterol, HDL-cholesterol, triglycerides lipid peroxides in the serum and ascorbic acid content in the tissues was determined. The cholesterol-rich diet caused development of atherosclerotic changes, increased serum cholesterol and lipid peroxide levels and ascorbic acid concentration in the studied tissues. „Non-eru- cid-acid” rapeseed oil slowed down the development of experimental atherosclerosis in a degree comparable to the effects of sunflower oil.

Using Wistar rats the effect of exercise was studied on the level of lipid peroxides, superoxide dismutase activity in the serum and certain tissues, and the contents of triglycerides (TG), total cholesterol (TChol), cholesterol in high density lipoprotein fractions (HDL -chol and HDL3-chol) and alpha-tocopherol in the serum. Low-grade exercise decreased by about 10% the lipid peroxide level in the serum, the soleus muscle and myocardium. Greater exercise increased the lipid peroxide level in the studied tissues. In the liver the lipid peroxide level rose by 20% independently of the degree of exercise. Superoxide activity increased proportionally to the grade of exercise in the myocardium, the soleus muscle and the liver. The serum alphatocopherol level increased in the groups of animals subjected to exercise. In the group with higher grade of exercise a slight fall of TChol in the serum and a fall of HDL and HDL3, cholesterol.

The aim of the study was to determine the effect of the perinatal period on redox status indicators in the blood of ewes before and after lambing and during lactation. The study was performed on 12 ewes of the synthetic SCP line. Blood for testing of redox parameters was collected seven times: before pregnancy, 1.5 months and 24 h before lambing, 2 and 24 h after lambing, and in the fourth and eighth weeks of lactation. The following blood indices were determined by spectrophotometry: lipid peroxides, malondialdehyde, superoxide dismutase, catalase, plasma total antioxidant capacity, uric acid, urea, bilirubin, and creatinine. The tests showed that during the perinatal period reactions are generated which lead to oxidative stress. Oxidative stress in pregnant ewes was found to increase during the period before lambing and may persist even up to weeks 4-8 of lactation.

Celem pracy było zbadanie czy palmitynian retinylu redukuje stres oksydacyjny wywołany wysiłkiem fizycznym. Badania przeprowadzono na rosnących szczurach samcach rasy Wistar, które przez 10 dni biegały na bieżni z prędkością przesuwu 20 m/min. Szczurom podawano palmitynian retinylu w ilości 7,5, 15 lub 60 µg dziennie na zwierzą. Po tym okresie w osoczu oznaczano poziom retinolu, nadtlenki lipidowe i potencjał anty oksydacyjny oraz estry retinyłu w wątrobie. Stwierdzono, że palmitynian retinylu redukował stres oksydacyjny wywołany wysiłkiem fizycznym, a efektywność tego procesu nie zależała od dawki podanego palmitynianu.

Badano wpływ soli kadmu na zawartość nadtlenków lipidowych i aktywność enzymów przeciwutleniających w wątrobie ciężarnej samicy oraz wątrobie płodowej i siedmiodniowego szczura. Zatruwanie solami kadmu przez 20 dni powodowało wzrost poziomu peroksydacji lipidów i obniżenie aktywności enzymatycznej obrony przeciwutleniającej w wątrobie matczynej i płodowej. Zmiany te ( za wyjątkiem spadku aktywności reduktazy glutationowej) nie utrzymywały się w wątrobie siedmiodniowego szczura. Podawanie witaminy E obniżało poziom nadtlenków lipidowych w badanych narządach.

The sources of free radicals and antioxidant defence systems in living organisms are reviewed. Attention is focused on the role of dietary lipid oxidation products and antioxidants to maintain balance between factors promoting free radical mediated oxidation and the antioxidant defence mechanisms. Particular attention is paid to the influence of intake of vitamins with oxidative properties (vitamin C, vitamin E and ß-carotene) and polyphenols compounds in the prevention of coronary heart disease and cancer.

The increase in the lipid peroxide level in the serum and liver of female mice after bilateral ovariectomy evidenced antioxidant activities of female hormones. This increase was abolished upon administration of female hormones. Similar increase in the level of lipid peroxide was observed in the serum of women who had undergone bilateral ovariectomy. Injection of 2-hydroxyestradiol suppressed the increase in the lipid peroxide level in the liver of rats receiving whole-body gamma-ray irradiation. Considering that the mechanism of coronary atherosclerosis is ascribed at least in part to the increased level of lipid peroxides, estrogen therapy could be applied to women who had undergone bilateral ovariectomy prior to menopause or to normal women after menopause. 2-Hydroxyestradiol might be applied also to men.

There is growing evidence that proteins are early targets of reactive oxygen species, and that the altered proteins can in turn damage other biomolecules. In this study, we measured the effects of proteins on the oxidation of liposome phospholipid membranes, and the formation of protein hydroperoxides in serum and in cultured cells exposed to radiation-generated hydroxyl free radicals. Lysozyme, which did not affect liposome stability, gave 50% protection when present at 0.3 mg/ml, and virtually completely prevented lipid oxidation at 10 mg/ml. When human blood serum was irradiated, lipids were oxidized only after the destruction of ascorbate. In contrast, peroxidation of proteins proceeded immediately. Protein hydroperoxides were also generated without a lag period in hybrid mouse myeloma cells, while at the same time no lipid peroxides formed. These results are consistent with the theory that, under physiological conditions, lipid membranes are likely to be effectively protected from randomly-generated hydroxyl radicals by proteins, and that protein peroxyl radicals and hydroperoxides may constitute an important hazard to biological systems under oxidative stress.
