Abstract

The aim of this work was to study the impact of modification of fatty acids composition of laboratory animals' diet in the presence of plasmalogenes (PG), astaxanthin (ASTA) and their combination on animals' adaptation potential in stress conditions. The fatty acids composition of diet was altered with the use of lipid module, containing 88.7% of high oleic sunflower oil, 6.3% of coconut oil and 5% of micralagae Schizochytrium sp. oil. The experiment was conducted with the use of 80 male Wistar rats with initial body weight 125±5 g. Selected animals (n=50) were divided into 5 groups according to their activity in tests «Open field» (OF) and «Elevated plus-maze» (EPM). The animals of control group 1st were not exposed to physiological tests - this was an intact control group. The animals of control groups 1st and 2nd were treated with standard half-synthetic diets for 30 days [381 kcal/100 g of dry food, 20.1% of casein on calories, 10% of fat (the mixture of lard and sunflower oil in 1:1 ratio)]. In the diet of 3d group animals the sunflower oil (50% of fat in the diet) was substituted with lipid module, enriched with ASTA (4.0±0.3 mg/day/kg b.w.); in the diet of group 4 animals - with lipid module, enriched with PG (79.0±2.0 m...Continue Reading

ApoE, Lipids & Cholesterol

Serum cholesterol, triglycerides, apolipoprotein B (APOB)-containing lipoproteins (very low-density lipoprotein (VLDL), immediate-density lipoprotein (IDL), and low-density lipoprotein (LDL), lipoprotein A (LPA)) and the total cholesterol/high-density lipoprotein (HDL) cholesterol ratio are all connected in diseases. Here is the latest research.
