Objectives: This study was designed to evaluate the anti-diabetic effects of Spargaium stoloniferum Buchanan-Hamilton (Sparganii Rhizoma, SR) extract on diabetic rats. Methods: Diabetes was induced with Sprague-Dawley rats by high fat/high sucrose (HF/HS) diet for 4 weeks and injection of a single low dose of streptozotocin (STZ; 35 mg/kg). SR water extract at 500 mg/kg was orally administrated once a day for 4 weeks. Body weights, food and water intakes and urine volumes were measured. The levels of glucose, insulin, total cholesterol, glutamic oxaloacetic transaminase and glutamic-pyruvic transaminase (GPT) were measured in the sera of rats. Histological changes were observed in pancreas, liver, and kidney tissues by H&E staining. Results: The administration of Sparganii Rhizoma extract at 500 mg/kg in diabetic rats did not shown a significant difference in body weight changes and GPT levels, but showed meaningful changes in an increase of urination volume, and decrease of serum glucose and insulin levels. Total cholesterol and GPT levels were also significantly decreased after SR extract administration in diabetic rats. Furthermore, the abnormal changes of pancreas, liver and kidney were also improved by Sparganii Rhizoma extract administration. Conclusions: These results indicate that SR extract can improve HF/HS-diet and STZ-induced diabetic damages in rats through inhibition of the blood glucose and insulin increase.

Purpose: The purposes of this study were to identify the segments of the Home Meal Replacement (HMR) market according to food-related lifestyle of Japanese consumers, and to investigate its demographic characteristics, the HMR purchase status and needs of new HMR product development. Methods: A total of 2,720 domestic consumers living in Japan were surveyed using a self-administered questionnaire and 488 responses were returned. Excluding responses with significant missing data, 467 responses were used for data analysis. Results: As a result of cluster analysis, three consumer segments were identified. The diet-highly concerned segment had the highest food-related lifestyle score, followed by the diet-moderately concerned segment, and the diet-unconcerned segment (p<0.001). A significant difference in demographic characteristics among the three segments was found with respect to the type of residence (p<0.05). There were significant differences in the main place (p<0.01) and average expense (p<0.001) for HMR purchases by food-related lifestyle segments. In the case of new HMR products that need further development, 'low-sodium products' had the highest demand scores in all three segments. In the diet-highly concerned segment, the mean scores of demand for new products were significantly higher than those in the other segments (p<0.001). Conclusion: The findings of this study can be used to develop new products for the Japanese' HMR market. The segments identified in this study should be updated and revised regularly to reflect changes in the characteristics of each food-related lifestyle segment.

To estimate the amount of daily salt intake by source of food and urinary sodium excretion, a dietary survey was conducted from August 27th to September 3, 1980. The salt concentration of six kinds of food was measured. The families of 25 womens' club leaders and 25 families of hypertensive patients were studied after they had been given a short course of education on lowsalt diet. The results were as follows: 1. The average amount of high-salt foods eaten daily by the study group were as follows: 4.5 Gm. in the form of table salt 16.8 ml of home-made soy sauce 6.20 ml of commercial soy sauce 11.9 Gm. of home-made red-pepper bean paste 12.0 Gm. of home-made soy-bean paste 120.7 Gm. of Kimchi 2. The average NaCl concentration of each food was as follows: 99.5% in table salt, 22.5% in home made soy sauce, 11.9% in Commercial soy sauce, 6.8 Gm% in home made red pepper bean paste, 9.2 Gm% in home-made soy-bean paste and the average concentration of various kinds of Kimchi was 2.7 Gm%. 3. The total amount of daily salt intake per adult was calculated as 14.3 Gm. By sources of food 4.5 Gm from table salt, 3.9 Gm from home-made soy sauce and 3. 3 Gm from Kimchi were taken daily Three other kinds of food were also minor sources of salt intake.4. The average amounts of individual daily salt intake were not significantly different between the hypertensive group and the normotensive group: the median of the normotensive group (11.7Gm.) was significantly lower than that of the hypertensive group (14.9Gm.). Therefore the womens' club leaders appeared to respond more quickly than the hypertensive group after low-salt diet education. 5. The average amount of sodium excretion in the 24 hour urine specimen was 234.7 mEq. From this finding the daily NaCl intake was estimated to be 15.8Gm.

This study was performed to provide basic for predicting the usefulness of Gastrodiae rhizoma(Cho'nma) as a food material for oriental applied diet therapy(YackSun). Thus, Gastrodiae rhizoma was used to develop a traditional Korean snack, Dasik. As a useful food resource, Gastrodiae rhizoma along with Cortex fraxini powder, was used to prepare Dasik. Cho'nma powder was added to the Dasik 63.2%(Dasik-1), 42.2%(Dasik-2) and 21.0%(Dasik-5) of Cho'nma powder to Dasik in one piece(5 g). The moisture and crude ash contents of the Dasik-1, 2 and 3 were analyzed. Physio-chemical analysis and a sensory test were also performed on the Dasik. Moisture and crude ash contents of Dasik-1 were 20.16% and 0.65%, respectively. Moisture and crude ash contents of Dasik-2 and Dasik-3 were 22.92 and 27.17% and 0.49 and 0.23% respectively. from the color test, the t value of Dasik-1 was found to be significantly low but the b value of Dasik-1 significantly high compared with the other preparations. The addition of Cho'nma had a tendency to impart high hardness, fracturability, gumminess and chewiness. Therefore, the addition of Cho'nma made the texture of Dasik denser. From the sensory test, the color, chewiness and overall acceptability of Dasik-1 were found to be significantly high. In conclusion, the addition of 63.2% Cho'nma per piece would be a useful recipe to enhance the quality of Dasik, and the flour Cho'nma showed better result than the Dasik-2 and Dasik-3.

Five type of formulated diet from agricultural by-products (ABP) were fed to four breedtype of cattle in feedlot. The ABP used are palm kernel cake (PKC), palm press fibre (PPF), palm oil mill effluent (POME), cocoa pod (COP), coffee pulp (COF) and pineapple waste (PAP). The formulated diets are PS (52% PKC, 15% PPF and 30% POME), PF (57% PKC, 20% PPF and 20% POME), PA (2% PKC and 55% PAP), CO (42% PKC and 55% COP) and CF (67% PKC and 30% COF) with 1% urea, 1% NaCl and 1% vitamins premix. The cattle breedtypes are Kedah-Kelantan (KK), Brahman-KK (BK), Hereford-KK (HK) and Sahiwal-Friesian (SF). The result showed that breedtype significantly affect all the carcass characteristic except dressing percentage. Each breedtype has it's specific carcass characteristics. HK cattle gave high marbling, BK has high % of carcass bone, KK has high % of carcass meat and low % of carcass fat (lean meat type) and SF has high % of carcass fat. Diet-type significantly affect the deposition of fat in the carcass. High moisture diets (PA and CO) produced significantly higher % carcass bone, the lowest % carcass fat and the highest % carcass meat (65.3%). PF, CF, PA and CO diets produced 63.4%, 59.9%, 55.3% and 54.1% carcass meat respectively.

Author have already reported that urinary aldosterone excretion of the Korean who usually eat high sodium diet is significantly lower comparing with the American, although the plasma aldosterone concentration is identical in the former with that of the latter. Measurement of urinary aldosterone excretion and Plasma concentration only is insufficient to establish the pressence and/or mode of evolution of the Korean. In this experiments, aldosterone secretion rate(ASR) was measured in normotensive Korean during high and low dietary sodium intake with or without additional potassium supply. Results were as follows; 1) In normal Korean, dietary sodium restriction resulted in appreciable increase in ASR, and a sustained increase in urinary aldosterone excretion with an increase in plasma level. 2) Oral potassium loading easily stimulated the adrenal cortex of the Korean who already adapted to a high sodium diet when dietary sodium is still identical with not·mal American. 3) Quantitative relationships between aldosterone secretion rate, plasma concentration and urinary excretion of aldosterone were altered by potassium loading. 4) Urinary aldosterone excretion didn't reflect concurrent increase aldosterone secretion in subjects with Potassium intake. It was discussed that the changes of tile relationships and of adrenal hyper response on Potassium Beading in the Korean will be elucidated by measuring the metabolic clearance rate.

The objective of this study was to investigate the influence of ambient temperatures on carcass characteristics of lambs fed concentrate diets with or without $NaHCO_3$ supplementation. A slaughter study was carried on 12 male Black Belly Barbados lambs randomly drawn from a growth trial (35 weeks). The lambs were divided into four equal groups and allotted in a $2{\times}2$ factorial design. The lambs were allotted at random to two dietary treatments of a basal diet (35:65 roughage:concentrate) or basal diet supplemented with 4% $NaHCO_3$ at different ambient temperatures ($20^{\circ}C$ and $30^{\circ}C$) in an environment controlled chamber for 10 days. Lambs were slaughtered for carcass evaluation at about 262 days of age (245 days of growth trial, 7 days adaptation and 10 days of experimental period). Ambient temperature had significant (p<0.05, p<0.05, p<0.01, and p<0.001) effects on meat color from the ribeye area (REA), fat, leg and longissimus dorsi muscles with higher values recorded for lambs in the lower temperature group than those from the higher ambient temperature group. Significant differences (p<0.05) in shear force value ($kg/cm^2$) recorded on the leg muscles showed higher values (5.32 vs 4.16) in lambs under the lower ambient temperature group compared to the other group. Dietary treatments had significant (p<0.01, p<0.01, and p<0.05) effects on meat color from the REA, fat, and REA fat depth ($cm^2$) with higher values recorded for lambs in the $NaHCO_3$ supplementation group than the non supplemented group. Similarly, dietary treatments had significant differences (p<0.05) in shear force value ($kg/cm^2$) of the leg muscles with the $NaHCO_3$ groups recording higher (5.30 vs 4.60) values than those from the other group. Neither ambient temperature nor dietary treatments had any significant (p>0.05) effects on pH, and water holding capacity on both muscles. These results indicated that $NaHCO_3$ supplementation at low ambient temperatures had caused an increase in carcass characteristics leading to significant effect on meat quality.

마그네슘, 칼슘 및 인삼을 첨가하여 사육한 토끼의 혈청콜레스테롤 농도에 미치는 영향을 조사하여 다음과 같은 결론을 얻었다. 1. 인삼분말의 급여로 체중증가는 별차가 없었으며 간장의 무게는 상당한 증가를 나타냈다. 2. Total cholesterol은 인삼 4mg을 첨가한 실험군에서 가장 낮았고, 마그네슘과 칼슘이 1:2로 급여한 군에서 낮게 나타났다. 3. Free cholesterol과 cholesterol ester도total cholesterol의 경우와 같이 인삼 4mg을 첨가한 것과 마그네슘과 칼슘을 1:2로 급여한 실험군에서 가장 낮았다. 4. Total cholesterol이 가장 낮은 실험군에서 LDL이 가장 낮았으며, HDL/T-CHOL의 비는 가장 높게 나타났다. 5. Triglyceride와 phospholipid에 있어서는 인삼 첨가로 TG의 양은 점점 감소되었으나 PL의 경우는 상당히 증가되었다. 6. 전해질의 경우는 마그네슘과 칼슘을 1:2로 첨가하고 인상 4mg을 급여한 실험군의 $Na^+$이 120mEq/l, $K^+$이 6.8mEq/l를 보여 인삼이 전해질의 이동에 크게 작용하고 있는 것으로 생각된다. 이상과 같은 결과로 인삼은 토끼의 혈청 전해질의 분포상태와 콜레스테롤의 농도에 영향은 주며, 콜레스테롤 농도를 저하시키는 작용을 함과 동시에 지방질을 감소시키고 인지질은 증가시키는 작용을 하는 것으로 추정된다.

In order to investigate the differences of nutrient intakes by the economic status and different age groups and to identify the nutritional risk group and its specific nutrition problem, 2001 Korean National Health and Nutrition Survey were analyzed. The subject's numbers of 9,391 were classified into four classes such as low (14.2%), medium (37.2%), high (26.0%), and high above (22.6%) on the basis of the family monthly income and the 2001 Korean minimum cost of living according to the family size. Mean intakes of energy and all nutrients assessed by the RDAs, lipid-energy %, and MAR were increased as the economic status were going up. Na intake expressed per 1,000kcal was in reverse. Nearly a half(45.5%) of the low-income people seemed to take nutritionally inadequate diet in consideration with MAR values. Deficiencies of iron and even energy in the toddlers (1 to 2 years) of low-income class were of great concern. Adolescent age group has been observed that their calcium and iron intakes, and possibly energy, were appeared to be the most deficient among all the age groups regardless of the economic status. For the elderly in all the economic status except high-above class, calcium, vitamin A, and riboflavin were commonly deficient nutrients. Calcium deficiency was appeared throughout nearly all the ages except toddlers and all the economic classes. Even in the high-above class 57.3% took insufficient amount of calcium.
