Badano wpływ wapnia i rodzaju tłuszczu w diecie na gospodarką lipidową w osoczu krwi szczurów. Stwierdzono, że wyższa zawartość wapnia w diecie miała korzystny wpływ na stężenie lipidów w osoczu badanych zwierząt, a z zastosowanych tłuszczów najlepszy wpływ na oznaczane składniki lipidowe, z wyjątkiem cholesterolu HDL, miał olej słonecznikowy.

The aim of this study was to investigate the effect of calcium and type of fat in diet on blood serum lipid metabolism in rats. Female Buffalo rats were divided into 6 groups (n= 10) and fed diets with 15% of fat (butter, sunflower oil or fish oil) and 0.5% or 1 % Ca for 4 weeks. At the end of the experiment the rats were anaesthetised with bioketane and blood samples were collected by heart puncture into tieparinized test-tubes. After centrifugtion, total lipid blood serum content was determined by the Lachema test kit and total choresterol, HDL choresterol and triacylglycerol contents werw determined by the Biosystems test kit. It was found that the blood serum lipid content in rats depeneded on the type of fat and quantity of Ca in the diet. The lowest blood serum lipid content was found in rats fed diets with sunflower oil. In the rats receiving diets with 1% Ca, blood serum total lipid and choresterol contents were significantly lower than in rats fed diet with 0,5% Ca. The diets with 1% Ca did not have a significant effect on blood serum HDL choresterol and triacylglycerol concentrations in rats. The only thing that affected this lipid content in blood serum was the type of fat in diet. The highest concentration of HDL choresterol in blood serum was found in rats fed diets with fish oil, and the lowest in rats fed diets with sunflower oil. the highest concentration of triacylglycerols in blood serum was found in rats fed diets with butter, and the lowest in rats fed diets with sunflower oil.
