        The aim of the study were to investigate the influences of krill (Euphausia superba) meal on the body weight, lipid metabolism functional improvement, blood glucose level, protein component in the sera of rats which fed experimental diets for 5 weeks. Serum concentrations of total cholesterol, Low-Density Lipoprotein (LDL)-cholesterol, free cholesterol, triglyceride (TG), phospholipid (PL) and blood glucose were higher in the control diet group (G1 group) than the control diet plus 10% krill meal group (G2 group), the control diet plus 20% krill meal group (G3 group), the control diet plus 30% krill meal group (G4 group), and a general dose and time independent one-way analysis of variance was performed to assess efficacy. Conversely depending on the content of krill meal for the High-Density Lipoprotein (HDL)-cholesterol level, it showed higher results. The concentrations of total protein, albumin and globulin in sera, there were not significant difference among the groups (p<0.05). The results indicate that a krill meal diet effectively inhibited increases in lipid elevation, blood glucose level in the sera of rats.

        Although rice has been cultivated as a major food crop for approximately 5,000 years, the interest of customers in ‘scented rice’ is a recent trend in the Korean market. As a part of developing a germinated scented rice variety, the newly bred scented rice variety ‘Cheonjihyang-1 se’ was germinated for 24 h, and changes in profiles of flavor-related volatiles, lipophilic phytonutrients, and fatty acids were investigated. The profiling of volatile compounds by using a headspace-gas chromatography-mass spectrometry (HS-GC-MS) revealed a total of 56 odor-active flavoring compounds; 52 at the pre-germination stage, 51 at the post-germination stage, and 47 common at both stages. The major flavoring compounds were nonanol and benzene, which constituted 11.5% and 6.6%, respectively, of the total peak area in pre-germinated rice, and 19.4% and 6.5%, respectively, in post-germinated rice. Germination induced an increase in 13 flavoring compounds, including 3,3,5-trimethylheptane and 1-pentadecene, which increased by 763 and 513%, respectively by germination. However, we observed a germination-induced decrease in most of the other flavoring compounds. Especially, the most important scented rice-specific popcorn-flavoring compound, 2-acetyl-1-pyrroline, showed 89% decrease due to germination. Furthermore, the germination of scented rice induced a decrease in the content of various phytonutrients. For example, the total contents of phytosterols, squalene, and tocols decreased from 207.97, 31.74, and 25.32 μg g -1 at pre-germination stage down to 136.66, 25.12, and 17.76 μg g -1 , respectively at post-germination stage. The fatty acid compositions were also affected by germination. The composition of three major fatty acids, linoleic, oleic, and palmitic acids, increased from 36.6, 34.2, and 24.4%, respectively, at the pre-germination stage to 37.9, 36.9, and 20.7%, respectively, at the post-germination stage. All these results suggested significant changes in the flavor-related compounds and phytonutrients of the scented rice variety ‘Cheonjihyang-1 se’ during the process of germination, and subsequently the need for developing a more precise process of germination to enhance the flavor and nutritional quality of the germinated scented rice products.

        This study was designed in order to determine the influences of haw (Crataegus pinnatifida BUNGE) on the lipid metabolism syndrome. Sprague Dawley rats, 7 weeks old, were given four different types of diets for 5 weeks: ND group (noncholesterolemic diet), HE group (non cholesterolemic diet+haw extract), CD group (cholesterolemic diet), CH group (cholesterolemic diet+haw extract). Concentrations of LDL-cholesterol, triglyceride, phospholipid, free cholesterol, cholesteryl ester, blood glucose were remarkably higher in the CD group than the other groups. But by treatment of haw extract group with cholesterolemic diet (CH group) were significantly decreased compared with CD group. Cholesteryl ester ratio was no difference between CD group and CH group. These results indicate that Crataegus pinnatifida BUNGE would be effective in lipid metabolism syndrome.

        This study was conducted to examine the influences of chitosan, sericin and collagen extract complexes (1:1:1, w/w/w, CSC-F-005) in blood glucose and lipid concentrations in the sera of streptozotocin (STZ, 55 mg/kg BW, IP injection)-induced diabetic rats (SD strain) fed on experimental diets for 5 weeks. The concentrations of blood glucose, total cholesterol, HDL-cholesterol, ratio of HDL-cholesterol concentration to total cholesterol, atherosclerotic index, LDL-cholesterol, free cholesterol, cholesteryl ester, triglyceride (TG) and phospholipid (PL) in serum were effective on the metabolic regulation in diabetic rats. The activities of alkaline phosphatase (ALP) and aminotransferase (AST, ALT) in serum were lower in the extract complexes (CSC-F-005) than in the diabetic rats. The results shown above suggested that CSC-F-005 extract complexes supplementation effectively improvement of blood glucose and lipid components in the serum of STZ-induced diabetic rats.
