title: Rapana venosa consumption improves the lipid profiles and antioxidant capacities in serum of rats fed an atherogenic diet.
abstract: In the recent years, the consumption of seafood has increased. There are no results on the studies of Rapana venosa (Rv) as a supplementation to the diets. We hypothesized that Rv would increase antioxidant capacity and reduce blood lipids, based on the composition of bioactive compounds and fatty acids. Therefore, the aim of this investigation was to evaluate in vitro and in vivo actions of Rv from contaminated (C) and non-C (NC) regions of collection on lipid profiles, antioxidant capacity, and enzyme activities in serum of rats fed an atherogenic diet. Twenty-four male Wistar rats were divided into 4 groups of 6 each and named control, cholesterol (Chol), Chol/RvC and Chol/RvNC. Rats of all 4 groups were fed the basal diet, which included wheat starch, casein, soybean oil, cellulose, vitamin (American Institute of Nutrition for laboratory animals vitamin mixtures), and mineral mixtures (American Institute of Nutrition for laboratory animals mineral mixtures). During 28 days of the experiment, the rats of the control group received the basal diet only, and the diets of the other 3 groups were supplemented with 1% of Chol, 1% of Chol, and 5% of Rv dry matter from C and NC areas. Dry matter from C and NC areas supplemented diets slightly hindered the rise in serum lipids vs. Chol group: total Chol, 13.18% and 11.63% and low-density lipoprotein Chol, 13.57% and 15.08%, respectively. Cholesterol significantly decreased the value of total antioxidant capacity. The supplementation of Rv to the Chol diet significantly affected the increase of antioxidant capacity in serum of rats, expressed by the 2,2'-azinobis (3-ethylbenzothiazoline-6-sulfonic acid) method. The water extracts of Rv exhibited high binding properties with bovine serum albumin in comparison with quercetin. In conclusion, atherogenic diets supplemented with Rv from C and NC areas hindered both the rise in serum lipids levels and the decrease in the antioxidant capacity. Based on fluorescence and electrospray-ionization mass spectrometry profiles and in vivo studies, changes in the intensity of the found peaks were estimated in the serum samples after supplemented diets. These findings indicate that the supplementation of Rv to the atherogenic diets improve the lipid profiles and the antioxidant status in serum of rats.
