A nutrition survey of 198 children, 6 to 12 years old, in the Song Myeon Elementary School and Sam Song Elementary School, located in remote villages of Gaesan county, Chung Buk province, was undertaken between July 11 and 16, 1988, to investigate dietary and nutritional status. Mean values of height, weight, sitting height, arm circumference, girths of chest, and weight for height were 98%, 96%, 101%, 94%, 103% and 98%, respectively, of Korean standards. Compared with the standards for Korean children and values for Yun Jung Elementary School children of Youido, Seoul, anthropometric data of subjects surveyed showed slightly lower results than the standards and further lower results than those of Yun Jung Elementary School children. mean hematocrit value was 39.8±3.1%. 15.3% of subjects were proven to be anemic according to the hematocrit criterion established by the WHO. Mean urinary urea nitrogen/creatinine ratio was 7.9±3.3. Energy and nutrient intake were 61.2 to 134.4% of the RDA's; except for intake of ascorbic acid, most nutrients were below the RDA's. Carbohydrate provided 72% of total energy intake; protein accounted for 11%; fat provided 17%. Family environment, anthropometric data and results of biochemical tests were positively correlated with nutrient intake. The survey emphasizes the need for a nation wide school lunch program.

Thirty mael Sprague Dawley rats of 3 weeks of age were adopted to investigate changes in nutritive quality of the traditional, fermented soybean foods, Meju and Chungkugjang prepared by culturing with Aspergillus oryzae and the rice straw, respectively. The levels of each dietary protein were set at 10% . The effect of supplementation of fermented soybean on the rat diet was evaluated by measuring growth rate, feed efficiency. weight of the pancreas and biological values, such as NPU, PER and NPR on day 10. After incubation of soybean with Aspergilllus oryzae and the rice straw, the contents of crude protein, crude fat and crude ash were increased, but the levels of crude fiber and nitrogen-free extract were reduced. The amounts of feed intake, body weight gain an feed efficiency were greater for the rats fed dietscontaining heated unfermented soybeans or Meju compared to rats fed the diet containing raw soybeans. Pancreating enlargement was observed in the rats fed diets containing raw soybeans. The values of NPR and PER in rats fed diets containing Meju and Chungkugjang were significantly higher than those of rats fed diets containing raw soybeans. The values of NPU in rats fed diets containing raw soybans, heated unfermeted soybeans. Meju and Chungkugjang were 39.40%, 40.60%, 45.00% and 46.205, respectively, demonstrating no significant differences.

To evaluate the effect of the feeding program of brown rice flake with soy milk or cow's milk to school children in rural areas. The survey was conducted twice before and after practice of feeding in March and July of 1990. The survey covered a total of 87 children aged from 7 to 12 in Ypsuk elementary school located in remote village of Sangju county. Kyung Buk province and the branch school of Songmyun elementary school located in remote village of Goisan county. Chung Buk province. Family environment dietary intake anthropometric data and biochemical tests were examined. The results are summerized as follows: The mean balance and food diversity at lunch were significantly lower than those at breakfast and dinner. Mean daily energy and nutrient intakes were below the Korean RDA's except for intakes of niacin vitamin A and ascorbic acid Especially intake of calcium was not reached to 50% of Korean RDA's. Most of anthropometric data of subjects surveyed showed slightly higher results in summer than those in spring except for weight for height and sitting height for height. The percentage of anemic according to hematocrit criterion was not reduced during this period. however urinary urea nitrogen/creatinine ratio was improved. The conbined feeding program of brown rice flake with soy milk or cow's milk was not sufficient to support the children's growth. So the survey recommends the support of goberment to the school lunch program in the remote village.

Plant nutrients are believed to provide protection against various diseases including inflammation. Since interactions of the cell adhesion molecules are known to play important roles in mediating inflammation, inhibiting adhesion protein upregulation is a possible therapeutic target. In this study, the interacellular adhesion molecule-1 (ICAM-1) was induced in human umbilical endothelial cells (HUVECs) after stimulation with $TNF-{\alpha}$. In addition, alginate, ascorbic acid and allicin were demonstrated to inhibit the $TNF-{\alpha}$ induced expression of ICAM-1 on the HUVECs in a dose-dependent manner. These compounds also inhibited the production of NO and $H_2O_2$ induced by $TNF-{\alpha}$, which suggests that the inhibition of ICAM-1 expression by the three compounds may be due to the modulated production of the reactive oxygen/nitrogen components. Overall, these results indicate that these dietary components have a therapeutic potential in the treatment of various inflammatory disorders associated with an increase in endothelial leukocyte adhesion molecules.

A 152 day trial was conducted to see the effect of feeding naturally fermented wheat straw (FWS) with either energy, protein or energy protein supplements on the growth of buffalo calves. Twenty four male buffalo calves (10-12 months old) divided in 6 equal groups were individually offered FWS as sole roughage along with either conventional concentrate mixture (conc), maize grains (M), solvent extracted mustard cake (DMC), M-DMC mixture (50:50), deoiled rice bran (DRB) or uromol bran mixture (UBM) in 70:30 ratio. The digestibility of nutrients, nitrogen retention and nutritive value was maximum in FWS:UBM followed by FWS:DMC and FWS:Conc groups. Almost, all the blood parameters were observed well within the normal range except that of blood urea (FWS:UBM) and creatinine (FWS:DMC and FWS:DRB). The dietary combination in which FWS was supplemented with only conventional protein supplement like DMC proved to be highly efficient as far as live weight gain was concerned. FWS supplemented with energy-protein combination i.e. MDMC could also be used as complete feed for growing calves in comparison to conventional feeding system.

The present paper gives a general overview on amino acid nutrition mainly focused on the concept of ideal protein and amino acid requirements in swine and poultry. Also, the nutritional, economic and environmental roles of synthetic amino acids are presented. A special emphasis has been given to the protein sparing effect by the supplementation of synthetic amino acids into diet and to the effect of this supplementation on growth performance and reduction of environmental pollutants in swine and poultry manure. It is concluded that the supplementation of limited amounts of synthetic amino acids (0.1 to 0.3%) to diets for swine and poultry could spare 2 to 3 percentage units of dietary protein and substantially reduce nutrient excretion, especially nitrogen. Immunocompetency as affected by amino acid nutrition is also introduced and the importance of threonine for the synthesis of immunoproteins in colostrum and milk to maintain piglets' health and intestinal integrity has been emphasized. Finally, some speculation on the future of global amino acids market is presented in conclusion.

This study was performed to investigate the effects of different kinds of dietary protein [plant protein ; Isolated Soy Protein(ISP), animal protein ; casein] on protein and lipid metabolism in rats fed with coffee and/or methionine in diet during four weeks of growing period after weanling. Forty male growing rats fo Sprague-Dawley strain, weighing 92.5$\pm$1.8g, were distributed into 8 groups by randomized complete block design, and fed diets containing 15% of protein by weight either as ISP or casein and 10% ofcalories as corn oil, supplemented with coffee and /or methionine for 4 weeks. Coffee were added at a concentration of 1.4% of diet as instant coffee, and methionine were added to ISP or casein diet to be 0.6% of diet as DL-methionine. Results were followed ; Body weight gain, F.E. R and P.E.R tanded to be higher in methionine added groups than non-methionine groups. The nitrogen content of feces was significantly higher in coffee groups than non-coffee groups, and tended to be higher in ISP groups than casein groups. but was not significantly different with or without methionine. thus, apparent protein digestilbity was significantly lower in coffee groups than non-coffee groups and was significantly lower in ISP groups than cesein groups, but was not significantly different with or without methionine. Total cholesterol content of serum tended to be higher in coffee groups than non-coffee groups, and tended to be lower in methionine groups than non-methionine groups.

A 4-week energy balance study was conducted to estimate the energy expenditure (EE) of 16 college age men and women, 20 to 26 year of age, by measurement of energy intakes and changes in body energy(BE) content(intake/balance technique), keeping their normal living pattern and maintenance body weight. Energy intake was measured by bomb calorimetry and estimated by food table. Fecal energy loss was calculated from nitrogen excreted. Fat mass was determined from body density estimated from skinfold tickness. 1) Gross energy (GE) intakes calculated from food table was not only 13.4% lower than those of bomb calorimetry but also lower 4 and 5% than metabolizable energy(ME) intakes for the male and female subjects, respectively. 2) Fecal energy loss was 7.2% and 6.9% proportion of the gross energy intake for the male and female subjects, respectively. 3) Mean daily metabolizable energy intakes estimated by subtract fecal and urinary energy loss was 2467kcal for the male subjects and 1897kcal for the female subjects. 4) Total body energy change estimated from body composition change over 31 days was decreased 7672kcal for the male subjects and 2689kcal for the female subjects. 5) Mean daily energy expenditure was 2714kcal (45kcal/kg of body weight) for the male subjects and 1984kcal(40kcal/kg of body weight) for the female subjects. 6) The estimated energy expenditure of college-age subjects in this study provide evidence to support the Recommended Dietary Allowances for energy of Korean normal adult.

Urinary excretion of total amino acids was measrued in normal and diabetic rats, streptozotocin-induced diabetic rats excreted increased amount of urinary total amino acids and nitrogen. This suggested increased degradation of body protein. Although excretion of total amino acids increased in the diabetic rats, the amino acid pattern of amino acids for both groups were very similar. The efficiency of dietary protein utilization was significantly lower in diabetic rats then that of normal rats. Streptozotocin injeciton affected the urinary excretion of 3-methylhistidine whereas diet did not. These findings suggest that the rate of urinary excretion of total amino acids can be empolyed as an index of protein metabolism, particulary as a simple index in the assesing the status of protein nutrition.

Seventy two Black Bengal goats on road side grass based diet were fed on 0, 20, 40, 80, 100 or 120 g of fish meal (FM)/goat/day with or without ad libitum access to urea molasses block(UMB). The purpose was to assess the interaction of undegradable protein (UDP) and fermentable nitrogen(N) supplementation on feed intake, nutrient digestibility and growth of goats. Live weight gain of goats increased linearly with the increasing of dietary fish meal as an undegradable protein source. With the increasing level of fish meal the live weight gain(g/day) was 17, 23, 46, 48, 48 and 52 with urea molasses block and 12, 21, 31, 49, 47 and 47 without urea molasses block. It was concluded that the beneficial effects of urea molasses feeding to accelerate the dry matter intake, TDN intake and nutrient digestibility observed could not be exploited in terms of live weight gain.
