Abstract

The aim of our study was to determine the ability of broccoli sprouts to influence the intensity of lipid peroxidation in mice fed a high-calorie cafeteria diet. Materials and methods. In this study, C57BL/6J mice were used. For determinatiom of lipid peroxides (LOOH), we used a method based on the ability of lipid peroxides to convert Fe2+to Fe3+. Then Fe3+ forms a complex with xylenol orange that absorbs light at 580 nm at low pH. The reaction mixture contained coumene hydroperoxide (1 mM), FeSO4*7H2O(1 M), xylenol (4 mM), water and supernatant. Differences between groups were analyzed by Duncan's test for multiple comparision. Results. During the experiment, we monitored the changes in body mass of mice fed with different diets. There were no differences in LOOH levels in cortexes of mice from all experimental groups, but there was a tendency to the lower content of LOOH in the brain of mice fed with cafeteria diet and broccoli. No statistical differences in levels of LOOH were found between groups, but LOOH levels tended to the highest in the groups fed with broccoli sprouts alone and cafeteria diet. A significant difference was observed in the muscles (C) between the broccoli sprout group and the cafeteria diet + broccoli group. We also found a significant difference between the group fed with the cafeteria diet and the cafeteria diet + broccoli, which may indicate protective effects of broccoli on lipid peroxidation on cafeteria diet. Conclusions. Mice fed with cafeteria diet and broccoli spouts had higher body mass than control mice fed with standard group. Hypothalamus of mice fed with standard diet with broccoli spouts or with cafeteria diet showed a tendency to higher LOOH levels, whereas no effects of the diets were found on cortexes LOOH levels. The cafeteria diet + broccoli group had the lowest muscle LOOH content compared to all other groups. Also, LOOH levels tended to be lower in the cortexes in the hypothalamus of mice fed with cafeteria diet + broccoli as compared with the cafeteria diet group. This suggests the potential protective effects of broccoli spouts.
