The questionnaire was designed to evaluate socirydeweraphic background, the subjects' nutrition knowledge, and the support systerns for geriatric nutrition. Fasting venous blcod was colected for the analysis of biochemical parameters. Blood pressure, bene mineral contents (BMC), body weight (BW) and they height (BH) were measured at the same time. Only 49. 7% of the subjects correctly an swered four basic questions on nutrition. Food patterns for the elder1y were simple and modest. Several nutrition-related disorders for the elderly were including high systolic bbo pressure (44. 6 % ), hyPertriglyceridemia (25. 9 % ), high diasto1ic blood pressure (25. 1% ),obesity (24. 5% ), high PBG (20. 6% ), emaciation (19. 9%), high FBG (17.9%) and osteoporosis (16. 8%). These data indicate that the support systems for the geriatric nutrition will have to be improved.展开更多

(i) In the H22 hepatoma-transplanting test, MCP had antitumor action, but MCP residue did not show such action; 5-FU appeared to have more potent antitumor activities and more harmful effects than MCP. (ii) In the micronucleus (MN) test, MCP significantly decreased MN frequency. (iii) In the cancer cell culture systems, the MCP fat-soluble extract revealed inhibitory effects on the growth and proliferation of the human hepatoma and the gastric cancer cells in a dose-response manner. (iv) In the colony formation test, MCP also altered the morphology of human gastric cancer cells. It was suggested that MCP could be consumed not only by healthy subJects for cancer prevention but also by patients with cancer as supplernentary treatrnent in combination with anticarcinogenic drug such as 5-FU, cyclophosphamide (CP)展开更多

The data analyzed by multiple F test indicate that the fasting blood glucose (FBG) and the 2-h postprandial blood glucose (PBG) on the 30th and the 65th days after the food was ingested were significantly reduced (P = 0.001, P < 0.001, respectively), as was the glycosylated hemoglobin level at the end of the trial (P < 0.05). The final FBG and PBG of the subjects with initial FBG-O >200 mg% decreased on the average by 51.8 and 84.6 mg%. respectively; those with FBG-0 150-200 mg% decreased by 24.1 and 68.7 mg%; and those with FBG-O < 150 mg% decreased by 4.8 and 21.4 mg%. No significant changes in blood lipid indexes were observed, except that the triglycer-ide values of subjects with hypertriglyceridemia (>200 mg%) significantly decreased by 118.7 mg%. It was concluded that Konjac food is very useful in the prevention and treatment of hyperglycemia. (C)1990 Academic Press. Inc.展开更多

Samples of these vegetables were quantitatively examined by highperformance liquid chromatography (HPLC) on a C-18 reversed-phase column for individual carotenoid content. Pure reference compounds (alpha-carotene, beta-carotent, lycopene, canthaxanthin, and lutein) and internal standard (beta-Apo-8'-carotenal) were employed to quantify xanthophylls and carotenes in these vegetables. The results indicated that fresh, dark-green, leafy vegetables were high in beta-carotene (0.94-9.36 mg/100 g) and oxygenated carotenoids or xanthophylls, primarily lutein (0.94-7.39 mg/100 g),whereas lycopene and alpha-carotene were not prominent and canthaxanthin was non existent in these vegetables. These analyses suggest that consumption of carotenoids such as lutein in addition to beta-carotene may be associated with a lower risk of cancers展开更多
