Activity of paraoxonase 1 and lipid profile in rats fed cornelian cherry or chokeberry in different types of diet

The study investigates effects of addition of cornelian cherry fruits or chokeberry juice on: activity of paraoxonase 1, lipid profile as well as essential elements in 3 types of diet: control, fructose, high-fat in Wistar rats. For 5 weeks 9 groups of male rats were fed control, fructose, high-fat diets as well control, fructose and high-fat diets enriched with cornelian cherry fruits or chokeberry juice: Activity of paraoxonase 1 was marked both in plasma and liver. Lipid parameters, calcium and magnesium were determined in plasma.Chokeberry juice better than cornelian cherry influenced on activity of paraoxonase 1 and lipid profile in conjunction with different type of diet. Protective effect of antioxidant products such an cornelian cherry or chokeberry depends on type of diet in which is used.
