The effect of enriched yoghurt on the antioxidant activities of rats poisoned with cadmium salts

Purpose Evaluation of the effect of yoghurts enriched with a complex of vegetable additives on the state of the antioxidant defense system, the content of triglycerides and cholesterol in rats exposed to toxic seeds with cadmium chloride. The purpose of this paper is evaluation of the effect of yoghurts enriched with a complex of vegetable additives on the state of the antioxidant defense system, the content of triglycerides and cholesterol in rats exposed to toxic cadmium chloride. Design/methodology/approach The studies were carried out on 72 male rats (Wistar), divided into six groups (n = 12): control, model of cadmium intoxication and receiving the developed dairy product, enriched with appropriate biologically active supplements (rosehip, rowan and hawthorn berries syrup and grape peel extract [rich in resveratrol]). Biochemical parameters of blood, homogenates of the liver and kidneys were analyzed. Findings The intensity of lipid peroxidation processes (in the liver, kidneys and erythrocytes) decreased in the group receiving dairy products enriched with berry syrups and grape peel extract (rich in resveratrol). The activity of catalase, total antioxidant activity and superoxide dismutase increased. In the groups receiving dairy products enriched with berry syrups, the total protein level in the blood increased, compared with Group 2. The content of triglycerides and cholesterol levels in groups receiving dairy products decreased significantly compared to animals intoxicated with cadmium chloride. Originality/value The topic of cadmium’s toxic effects on human and animal health and methods for solving this problem is very relevant.
