The aim of this study was conducted to investigate the proximate and nutritional compositions including mineral, vitamin, amino acids and fatty acids in Korean yam (Dioscorea batatas $D_{ECNE}.$). Carbohydrate (68.1%) possessed the large single constituent of yam. Small amounts of crude protein (16.9%), crude ash (5.8%) and crude fat (2.0%) contents were found. Yam was found to be good sources of essential minerals such as K (1295.5 mg/100 g), Mg (115.3 mg/100 g), Na (99.0 mg/100 g) and Ca (56.5 mg/100 g) but Zn (0.3 mg/100 g) content was low. Relatively abundant vitamin $B_1$ (11.5 mg/100g) could be observed while vitamin A, $B_3$ and $B_6$ were not found. The amino acid analysis revealed that the yam was superior with respect to glutamic acid (1770.6 mg%), lysine (1210.6 mg%) and urea (550.9 mg%). Essential amino acids were calculated to be 2954.5 mg%. The amino acid profiles showed that yam to be limiting in valine and leusine. Palmitic acid and linoleic acid were the most predominant fatty acids with the value of 31.5% and 41.5%, respectively. And the polyunsaturated fatty acids including linoleic acid and linolenic acid were present in a large quantities in yam. And it also contained higher amounts of unsaturated fatty acids compared saturated fatty acids.

The purpose of this study was to assess the nutrition education program for older adults at rural area. Eighty three adults (mean age ;55.6$\pm$11.9) participated in nutrition education program. Data collection includes serum and urine collections for health state. The impact of nutrition KAP (knowledge attitude and practice) and retention was examined among participants who were assessed at program entry 3 times of education and 1 month of follow-up. The results were as follows : The participants were composed 52 persons of under 60-year-old and 31 persons over 60 years. Of the 83 participants, 60 were females and 23 were males. Serum albumin and calcium content of females (3.5$\pm$1.2g/dl, 7.5$\pm$3.9mg/dl) were significantly lower than males(4.7$\pm$0.9g/dl, 11.2$\pm$4.6mg/dl). Serum TG and cholesterol contents of females (143$\pm$117mg/d1, 205$\pm$31mg/d1) were higher than males (101$\pm$86mg/dl, 192$\pm$19mg/dl) but not significantly different. The calcium (13.4$\pm$9.0mg/dl) and urea (743$\pm$440mg/dl) contents of urine excretion were also significantly lower in female than in males (19.7$\pm$11mg/dl, 1041 $\pm$535mg/dl). Via the question of nutrition attitude, the participants improved significantly between pre and post education (the score of pre, post and after 1 month, 6.7$\pm$1.8, 7.2$\pm$1.5, 7.2$\pm$1.8), and were also attributed to better personal feeling health by modified CMI test but food habit was not significantly improved. As the differences of age and gender groups were compared, under 60-year-old group had better nutrition practice score than over 60 years group.

This study was designed to observe the body growth and components of edible mugwort(Artemisia sp.) and medicinal mugwort(Kanghwa medicinal mugwort) . Twenty-four young rats of Sprague Dawley strain, body weight of about 89g were used in this study. They were fed on the basal diet(control diet) supplemented with 5% edible mugwort powder ( EM diet) and 5% medicinal mugwort powder( MM diet) for 4 weeks respectively. In proximate composition of nutrients of mugwort in dry basis(100g). crude protein (16.4g) and crude ash(11.8g) contents of EM were higher to about 2% than that of MM, but crude lipid content(4.3g) of EM was lower to about 2% than that of MM. However, the contents in calcium(6.9g) of MM was higher to 5.3 times than that of EM. but in Mn(17mg), Zn(0.5mg), Fe(131mg), Mg(337mg) of EM were higher to 2.8∼2.3 times and vitamin A(39,776 IU) of EM was higher to 2.9 times than that of MM respectively. Body wight gain rate and diet efficiency ratio of EM and MM diet group were similar to that of the control group. The contents of total protein, albumin, urea nitrogen. creatinine, uric acid, total cholesterol, HDL-C, LDL-C, glucose, amylase, transaminase (GOT, GPT) in serum exhibited no remarkable difference among of the EM and MM diet group but the level of LDH activity of MM diet group were significantly lower than that of the control group and EM diet group.

In other to find out the effect of N.K compound fertilizers, 17-0-17 and 17-0-14, a field experiment was conducted with rice (Oryza sativa L. Akibare). Results obtained were summarized as fellows: 1. The effect of compound fertilizer on the yield of paddy and nutrient uptake was not much differed from that of Urea and Muriate potassium. 2. It seemed that the compound fertilizer, 17-0-17, was rather pertinent for the top dressing at effective tillering stage than that at primodial stage, for its slow effectiveness. 3. From the viewpoint of increasing paddy yield and nutrients uptake as well as the exchangeable potassium content of soil after harvesting, it seemed necessary to give a serious consideration to the development of such a compound fertilizer as used in this experiment which was prepared by the Chosen Fertilizer Industrial Cooporation on a trial base.

Various products of karanj (Pongamia glabra) are utilized for industrial, health and animal agriculture applications in the Indian subcontinent. Despite a rich source of protein (CP, 28-34%), karanj cake was found to be slightly bitter in taste and toxic owing to the presence of flavonoid (Karanjin), restricting its safe inclusion in the livestock diets. Feeding trials with raw cake revealed its poor palatability and adverse performance among different categories of livestock including poultry. The present study was, therefore, aimed to detoxify karanj cake by various physico-chemical methods like solvent extraction, water washing, pressure cooking and alkali and acid treatments. The level of residual karanjin in raw and variously processed cake was quantified using high performance liquid chromatography (HPLC). The raw expeller karanj cake was found to contain about 0.19% of karanjin. Though a non-polar solvent, soxhlet extraction of expeller pressed cake with petroleum ether drastically reduced karanjin content (0.01%). Soaking of cake for 24 h in 1% NaOH (w/w) solution was found to reduce karanjin to a major extent with little further benefit by increasing alkali level. Milder alkalies like lime and fertilizer grade urea reduced the karanjin levels marginally. Similar was the case with mineral acids such as HCl and glacial acetic acid. It was, therefore, concluded that solvent extraction of karanj seeds would be the best method of detoxification as well as for more recovery of oil and karanjin.

This experiment was conducted to investigate the effects of crystalline isoleucine supplementation of a low protein, corn-soybean meal diet on the performance and immune function of weanling pigs. Forty-five crossbred ($Duroc{\times}Landrace{\times}Large\;White$) piglets, weighing an average of $11.00{\pm}0.07kg$, were assigned to either a control diet containing 20% crude protein (0.64% isoleucine), a 16% crude protein diet without isoleucine supplementation (0.41% isoleucine) or a 16% crude protein diet supplemented with isoleucine (0.64% isoleucine). Reducing the crude protein content of the diet from 20 to 16% significantly (p<0.05) reduced both average daily gain and feed intake. Feed conversion also tended (p=0.07) to be poorer for a low protein diet without isoleucine supplementation. Isoleucine supplementation of the 16% crude protein diet increased both gain and feed intake to a level similar to that obtained by pigs fed the 20% crude protein diet (p>0.05). Blood urea nitrogen, serum total protein and serum globulin were significantly (p<0.05) higher for pigs fed the unsupplemented 16% crude protein diet than for pigs fed the isoleucine-supplemented diet or the control. Egg albumin antibody titre decreased significantly (p<0.05) in pigs fed the diet with isoleucine supplementation, whereas the antibody titre of pigs fed the low protein and low isoleucine diet was similar to that of pigs fed the diet containing 20% crude protein and 0.64% isoleucine. It was suggested that crystalline isoleucine supplementation of a low protein and low isoleucine diet improved pig performance but suppressed humoral immune function.

BACKGROUND/OBJECTIVES: Arsenic, which causes human carcinogenicity, is ubiquitous in the environment. This study was designed to evaluate modulation of arsenic induced cancer by resveratrol, a phytoalexin found in vegetal dietary sources that has antioxidant and chemopreventive properties, in arsenic trioxide ($As_2O_3$)-induced Male Wistar rats. MATERIALS/METHODS: Adult rats received 3 mg/kg $As_2O_3$ (intravenous injection, iv.) on alternate days for 4 days. Resveratrol (8 mg/kg) was administered (iv.) 1 h before $As_2O_3$ treatment. The plasma and homogenization enzymes associated with oxidative stress of rat kidneys were measured, the kidneys were examined histologically and trace element contents were assessed. RESULTS: Rats treated with $As_2O_3$ had significantly higher oxidative stress and kidney arsenic accumulation; however, pretreatment with resveratrol reversed these changes. In addition, prior to treatment with resveratrol resulted in lower blood urea nitrogen, creatinine and insignificant renal tubular epithelial cell necrosis. Furthermore, the presence of resveratrol preserved the selenium content ($0.805{\pm}0.059{\mu}g/g$) of kidneys in rats treated with $As_2O_3$. However, resveratrol had no effect on zinc level in the kidney relative to $As_2O_3$-treated groups. CONCLUSIONS: Our data show that supplementation with resveratrol alleviated nephrotoxicity by improving antioxidant capacity and arsenic efflux. These findings suggest that resveratrol has the potential to protect against kidney damage in populations exposed to arsenic.

We have studied the effects of red wine on brain oxidative stress and nephropathy in streptozotocin (STZ)-induced diabetic rats. Diabetes was induced in Wistar rats with a single intraperitonally injection of STZ (50 mg/kg). Two weeks before and four weeks after injection, red wine was given orally in both normal and diabetic rats. Blood samples were taken from the neck vascular trunk in order to determine the glucose, triglycerides, total cholesterol, HDL-cholesterol (HDL-c), atherogenic index (AI), total protein, blood urea nitrogen (BUN), creatinine, insulin, lipid peroxidation products, reduced glutathione (GSH) and superoxide dismutase (SOD) and glutathione peroxidase (GSH-Px) activities. As well, we estimated the lipid peroxidtion, GSH and SOD, GSH-Px and catalase activities in brain and renal homogenates, and the excretion of albumin, proteins and glucose in urine over 24 h period. The administration of STZ caused significant increases in levels of glycosuria, proteinuria, albuminuria, glycemia, total cholesterol and AI, as well as in lipid peroxidation products in the brain, plasma and kidney, whereas it decreased the GSH content and SOD, GSH-Px and catalase activities. Treatment with red wine significantly prevented the changes induced by STZ. These data suggested that red wine has a protective effect against brain oxidative stress, diabetic nephropathy and diabetes induced by STZ, as well as it protects against hypercholesterolemia and atherogenic risk.

A mold producing large amounts of lipid were isolated from leaves, arable soils, rice straw, cow feces, compost heaps and fermented soybeans. Among various sources, the microbes from leaves produced the large amount lipids, which were identified as Aspergillus sydowi SW 4-1. This study was focused mainly on the optimization of cultural conditions for lipid production by A. sydowi SW 4-1 and the characterization of the produced lipids. A. sydowi SW 4-1 was cultivated in a medium containing 27% sucrose for 17 days at $27^{\circ}C$. Biomass was 4.99g/100ml of the cultural medium and lipid content was 41.4% on a dry biomass basis. The major fatty acids were palmitic acid, stearic acid, oleic acid, and linoleic acid.
