[Effects of polyphenols on activity of glycosyl hydrolases in the cecum of rats fed obesity inducing diets].

The results of experimental studies indicate that the preventive and therapeutic effects of polyphenols in obesity are accompanied by a significant decrease in the severity of dysbiosis caused by the predominance of fats and simple carbohydrates in the diet, especially fructose, and the restoration of the functional state of the microbiota. of the work was to study the effect of quercetin and resveratrol - polyphenols, widely represented in the daily human diet, on the activity of bacterial glycosidases in rats receiving diets high in fructose or fat and fructose. .

[Effects of quercetin on protective capacity in rats fed a high-fructose diet].

The purpose of the study was to determine effects of quercetin on protective capacity parameters in the experiment on rats fed a high fructose diet. Rats of the control group received a semi-synthetic (s/s) diet and water; animals from the 1st experimental group - s/s diet and 20% fructose solution instead of drinking water; rats of the 2nd experimental group- s/s diet with quercetin (0.1% indiet) and 20% fructose solution instead of drinking water for 20 weeks.

[Toxicological evaluation of colloidal nano-sized silver stabilized polyvinylpyrrolidone. III. Enzymological, biochemical markers, state of antioxidant defense system].

Nanosized colloidal silver (NCS) with primary nanoparticles (NPs) size in the range of 10-80 nm in aqueous suspension was administered to rats with initial weight 80±10 gfor the first 30 day intragastrically and for lasting 62 days with the diet consumed in doses of 0.1; 1.0 and 10 mg/kg of body weight b.

[Effects of rutin on protective capacity in rats].

The purpose of the study was to determine effects of rutin dietary administration on the activity of xenobiotic-metabolizing enzymes and antioxidant status. The study has been carried out on 3 groups of male Wistar rats (n = 8 in each), with initial body weight 100-120 g. Animals of the control group (1st group) received standard semi-synthetic diet, the experimental groups--the same diet with rutin in the amount of 40 mg/kg b.

[Effects of rutin on the activity of antioxidant enzymes and xenobiotic-metabolizing enzymes in liver of rats fed diets with different level of fat].

The study has been carried out on 6 groups of male Wistar rats, which received semi-synthetic diets within 28 days. Rats of 1st and 4th group received fat-free diet, 2nid.and 5th - diet containing standard amount of fat (10% by weight, 26% by caloric content; lard/sunflower oil - 1/1); 3rd and 6th group - a high-fat diet (30% by weight, 56% by caloric content).
