Perbaikan Parameter Lipid Darah Mencit Hiperkolesterolemia dengan Suplemen Pangan Bekatul

Dietary fiber is widely used as a functional food and recommended to reduce blood lipid level to prevent hypercholesterolemia. An experiment was conducted on the effects of rice bran that has high dietary fiber content on blood lipid parameters of hypercholesterolemic male mice, which was conducted at the Biology Education Department animal cages, Indonesia University of Education and the Veterinary Medicine Faculty Laboratory, Bogor Agricultural Institute from August 2011 to March 2012. The mice were randomly assigned into groups with 5 different treatments: negative control group i.e. normocholesterol mice with a standard diet without rice bran; positive control group i.e. hypercholesterolemic mice with a standard diet without rice bran; and groups with hypercholesterolemic mice with 16%, 38%, and 75% rice bran supplements. The parameters were body weight as well as blood serum, liver and feces cholesterol, triglyceride, high density lipoprotein (HDL-c), low density lipoprotein (LDL-c) and glucose levels. Body weight, blood serum and liver cholesterol as well as triglyceride and LDL concentrations decreased while serum HDL-c and feces cholesterol increased without any significant effect on blood glucose concentration with rice bran supplement. Supplementation of rice bran by 57% (14.30% of nonsoluble dietary fiber content) decreased body weight, total serum cholesterol, triglyceride, and LDL-c of 10.31%, 17.28%, 28.63%, and 79.35%, respectively, and increased HDL-c by 24.41%. Rice bran supplement reduced liver cholesterol levels by 57.76% and increased fecal cholesterol excretion by 39.68%. In conclusion, 57% rice bran supplementation is effective to improve blood lipid parameters of hypercholesterolemic male mice by increasing feces excretion and decreasing body weight with no change in blood glucose level.
