This study was carried out to determine the folate status of adolescent girls. Serum and red blood cell(RBC) folate levels of 132 Korean adolescent girls aged 12 to 15 years were evaluated by micorbioligical assay using Lactobacillus casei(ATCC 7469). Serum folate concentrations were less than 3ng/ml in 4.5% and 3 to 4.9ng/ml in 42.4%. Of the RBC folate values, 4.5% were less than 120ng/ml and 40.2% were 120 to 159ng/ml. These findings demonstrated that serum folate levels were subnormal in 46.9% and RBC folate levels were subnormal in 44.7% of the adolescent girls. Serum and RBC folate concentration tend to be high in folate supplemented subjects. There was no significant difference in serum and RBC folate levels, hemoglobin, and hematocrit values between regular meal group and irregular meal group.

The purpose of this study was to investigate of the dietary life and nutritional status of the Buddhist priests. Dietary life, the state of prepare a meal and menu are carried out through the questionnaire and the nutritional status is carried out through the analysis of the constituents of the blood. The results of this study can be summarized as follows. 1. The traditional temple's foods undergo a change with the variety and westernization of dietary life. 2. Buddhist priests take a carbohydrate centered meal and the intake of protein and lipid is tendency to lack, but the intake of vitamin and mineral is sufficient with various vegetables. 3. The content of the lipid compoents and glucose of blood are low and they are free from the danger of geriatric diseases but the content of triglyceride is very higher than the healthy general adults. Therefore it is necessary to improve the nutritional status of the buddhist priests with decrease the intake of rice and increase the various side dish and to develop the standard menu for the Buddhist priests.

This study was conducted to investigate the effect of ingestion of rice meal with red pepper(Capsicum annuum) as a seasoning upon the plasma gastrin concentration of normal human subjects in Korea. Thirteen normal human subjects including male and female(mean age: 21 years, range: $20{\sim}24\;years$) were studied. After an overnight(about 15 hrs) fast each subject ingested a test meal and a control meal on different days. The test meal consisted of 250 g toiled rice, 250 ml radish soup containing red pepper(dried powder, 3 g), 50 g vegetables and 200 ml barley tea, corresponding to 7.0 g protein, 9.0 g fat and 82 g carbohydrate and the control meal consisted of the same amount as the test meal except that the radish soup was supplied without red pepper. The venous blood samples were drawn before and after the ingestion of meals at the following times: -30, 0, 15, 30, 45, 60, 90, and 120 min for the measurement of plasma gastrin concentration by means of radioimmunoassay. 1) Plasma gastrin concentration in response to the ingestion of control meal without red pepper increased significantly compared with the concentration in fasting state. 2) The increase of plasma gastrin concentration after the ingestion of test meal(containing red pepper) was significantly higher than that after the control meal. It is inferred from the above mentioned results that the ingestion of red pepper as a seasoning has a stimulatory influence on gastrin release in normal human subjects.

The laying performance of Japanese quails fed graded levels of high glucosinolate ($92.5{\mu}mole/g$) rapeseed meal (RSM) was assessed. One hundred and twenty Japanese quails aged 1 day-old were assigned at random to four dietary treatments consisting of 0, 50, 75 or 100 g/kg RSM in the diet replacing part of the soybean meal and de-oiled rice bran in a standard quail ration. 12 female representative quails from each diet were selected at random and housed in individual cages from 7-20 wk of age. The egg production, feed intake and FCR was comparable among the different dietary groups. The egg quality characteristics, organoleptic evaluation of boiled eggs as well as the haematological (haemoglobin, total erythrocyte count, total leucocyte count) and biochemical (glucose, protein, cholesterol, aspartate amino transferase, alanine amino transferase and alkaline phosphatase) constituents did not differ significantly among the groups. The gross and histopathological studies of vital organs did not reveal any appreciable changes. The feed cost was reduced by the incorporation of RSM in the diet, but only the production cost of quails fed the 75 g/kg RSM was lower in comparison to other groups. In the present study, the laying potential of Japanese quail was well-maintained up to the 100g/kg dietary level of rapeseed meal.

The purpose of this study was to investigate the effects of nutrition counseling on diabetes management by determining changes in anthropometry and blood components as well as knowledge and practice of diet therapy and nutrient intake in 34 (male 11, female 23) type 2 diabetes patients. The knowledge and the practice of diet therapy, drinking, smoking and exercise were analyzed by questionnaires. Dietary nutrient intake were obtained from the patients by the 1 day 24-hr recall. Blood glucose level and blood pressure were measured before and 3 months after the treatment. The results are summarized as follows: Average weight (p<0.05) and body mass index (p<0.05) were significantly lower post-counseling. Fasting blood glucose levels (p<0.01) and postprandial-2hour blood glucose levels (p<0.01) were also significantly lower post-counseling. In lifestyle changes for self-management the patients showed significantly higher exercise habits post-counseling (p<0.01). Regarding their level of diet knowledge, they showed significantly higher levels post-counseling in six items such as importance of diet therapy for diabetes (p<0.001), principles of diet therapy (p<0.001), nutrient composition of foods (p<0.01), carbohydrate composition of foods (p<0.001), the prescribed calories (p<0.001) understanding food item and exchange units of cereals, grains (p<0.001) and fruits, juices (p<0.001). Regarding their diet practices, the patients showed significantly higher levels of practice post-counseling in keeping within permitted meal size (p<0.001), using food exchange lists (p<0.001), keeping exact meal times (p<0.01), and controling sweet foods (p<0.001). Protein (p<0.05), animal lipid (p<0.05), and vitamin C (p<0.05) intakes were significantly higher post-counseling.

Sodium restricted diets are known to lower blood pressure in salt sensitive, hypertensive patients. Thare is increasing evidence that potassium plays an important role as a protective factor in the regulation of blood pressure. The objective of the current study was to measure parameters of sodium, potassium, and chloride utilization as affected by feeding of substantial quantities of bread made from whole ground white torn meal, whole ground yellow corn meal, and whole ground wheat flour. The breads provided 40 percent of a caloric content of the constant, measured laboratory diet. The 28-day study was divided into an introductory period of 7-days and three experimental periods of 7-days each. Order of assignment to specific treatments for 12 healthy subjects were according to a complete randomized block design. Yellow corn bread diets resulted in the highest potassium retention (243 mg/day) and the lowest urinary sodium and potassium ratio (1.53 $\pm$ 0.26) numerically in comparison to the other test breads. The excretions of sodium and chloride were higher during controlled feeding periods than during the self-selected diet period(p < 0.05). This indicates a response to the higher intake of these electrolytes from the experimental diets than from self-selected diets. There was no significant difference in the effect of white corn bread, yellow corn bread, or whole wheat bread diet on electrolyte status in humans. However, the yellow corn bread diet resulted in a somewhat more favorable urina교 sodium to potassium ratio than that from white corn bread or whole wheat bread diet.

Objective: This experiment was conducted to investigate the influence of rapeseed meal (RSM) supplementation in weaning pig diet on growth performance, blood profile, carcass characteristics and economic analysis on weaning to finishing pigs. Methods: A total of 120 cross bred ([Yorkshire${\times}$Landrace]${\times}$Duroc) weaning pigs were allotted to 5 treatments in a randomized complete block design. Each treatment had 4 replications with 6 pigs per pen. Five different levels of RSM (0%, 2%, 4%, 6%, and 8%) were used as dietary treatments. Results: Overall, no treatment showed significant differences in growth performance with increased dietary RSM levels. The concentration of blood urea nitrogen (BUN) decreased as dietary RSM levels increased in 6 weeks (linear response, p<0.01). Total cholesterol, high density lipoprotein cholesterol, low density lipoprotein cholesterol, triiodothyronine, and thyroxine showed no significant differences, neither were there any significant differences in the immune response (IgG and IgA). As the dietary RSM levels of weaning pig diet were increased, no differences were found among dietary treatments upon performing proximate analyses of the pork after finishing. The influence of RSM supplementation on nutrient digestibility and nitrogen retention were not affected by dietary RSM levels either. With increased dietary RSM levels in the weaning pig diet, no differences among dietary treatments were found after performing proximate analyses of the pork's physiochemical properties. In addition, there were no significant differences observed in pork colors, pH levels, and economic benefits. Conclusion: Consequently, this experiment demonstrated that weaning pig's diet containing RSM influenced BUN concentration, but there were no detrimental effects on the growth performance of weaning pigs with up to 8% RSM in the diet.

The objective of this research was to evaluate the effects of dietary supplementation of blood meal (BM) as a source of histidine, and magnesium oxide (MgO) as a catalyst of carnosine synthetase, on carnosine (L-Car) content in the chicken breast muscle (CBM), laying performance, and egg quality of spent old hens. Four hundred eighty laying hens (Hy-Line$^{(R)}$ Brown), 95wk old, were allotted randomly into five replicates of six dietary treatments: T1; 100% basal diet, T2; 100% basal diet+MgO, T3; 97.5% basal diet+2.5% BM, T4; 97.5% basal diet+2.5% BM+MgO, T5; 95% basal diet+5% BM, T6; 95% basal diet+5% BM+MgO. Magnesium oxide was added at 0.3% of diets. The layers were fed experimental diets for 5wk. There were no significant differences in the weekly L-Car content in CBM among all treatments during the total experimental period, but some of the contrast comparisions showed higher L-Car in CBM of T6. The L-Car contents linearly decreased (p<0.01 or p<0.05) as the layers got older except in T4 (p>0.05). There were significant differences in egg weight (p<0.01) and soft and broken egg ratio (p<0.05). The control (T1) was highest in egg weight and T6 was lowest in soft and broken egg ratio. Among the parameters of egg quality, there were significant differences in eggshell strength (p<0.01) and egg yolk color (p<0.05). Magnesium oxide supplementation increased the eggshell strength and BM tended to decrease egg yolk color. Eggshell color, eggshell thickness, and Haugh unit were not influenced by BM and MgO. In conclusion, BM and MgO did not significantly influence the L-Car in CBM of spent layers. The L-Car content rapidly decreased as the layers became senescent. Eggshell strength was increased by MgO supplementation.
