The purpose of this study was to assess the nutritional status of iron and magnesium and the effect of von supplementation during 8 weeks(from 20 to 28 weeks of gestation) on serum iron and magnesium status of 31 pregnant women in Kyunsin area. The age, weight, and height of the subjects before pregnancy were investigated by questionnaires. At 20 and 28 weeks of gestation, data for food and nutrient intake were obtained by questionnaires and serum sample was obtained. According to the frequency of iron supplementation, subjects were divided into two groups(4$\geq$/wk) The mean iron supplementation of 5 $\geq$/wk group(63.mg/day) was significantly higher than 4$_2$ intakes were much less than the Korean RDA. Especially, calcium, iron and magnesium intakes showed half the levels compared with Korean RDA. At 28 weeks of gestation the serum total protein(p<0.001), albumin(p<0.01) and globulin(p<0.001) were significantly decreased. Total iron binding capacity(TIBC) was significantly increased(P<0.001), but serum ferritin(p<0.01) and magnesium(p<0.01) concentrations were significantly decreased. However, even 28 weeks of gestation 5$\geq$/wk group showed higher serum iron and ferritin concentration and lower TIBC than 4$\geq$/wk group. Therefore, iron supplementation should be conducted with concerning the mineral balance like magnesium.

BACKGROUND/OBJECTIVES: The prevalence of malnutrition among hospitalized children ranges between 12% and 24%. Although the consequences of hospital malnutrition are enormous, it is often unrecognized and untreated. The aim of this study was to identify the current status of in-hospital nutrition support for children in South Korea by carrying out a nationwide hospital-based survey. SUBJECTS/METHODS: Out of 345 general and tertiary hospitals in South Korea, a total of 53 institutes with pediatric gastroenterologists and more than 10 pediatric inpatients were selected. A questionnaire was developed by the nutrition committee of the Korean Society of Pediatric Gastroenterology, Hepatology and Nutrition. The questionnaires were sent to pediatric gastroenterologists in each hospital. Survey was performed by e-mails. RESULTS: Forty hospitals (75.5%) responded to the survey; 23 of them were tertiary hospitals, and 17 of them were general hospitals. Only 21 hospitals (52.5%) had all the required nutritional support personnel (including pediatrician, nutritionist, pharmacist, and nurse) assigned to pediatric patients. Routine nutritional screening was performed in 22 (55.0%) hospitals on admission, which was lower than that in adult patients (65.8%). Nutritional screening tools varied among hospitals; 33 of 40 (82.5%) hospitals used their own screening tools. The most frequently used nutritional assessment parameters were weight, height, hemoglobin, and serum albumin levels. In our nationwide hospital-based survey, the most frequently reported main barriers of nutritional support in hospitals were lack of manpower and excessive workload, followed by insufficient knowledge and experience. CONCLUSIONS: Although this nationwide hospital-based survey targeted general and tertiary hospitals with pediatric gastroenterologists, manpower and medical resources for nutritional support were still insufficient for hospitalized children, and nutritional screening was not routinely performed in many hospitals. More attention to hospital malnutrition and additional national policies for nutritional support in hospitals are required to ensure appropriate nutritional management of hospitalized pediatric patients.

Deflazacort, an oxazoline derivative of prednisolone, has been claimed to have anti-inflammatory effects with fewer side effects compared to prednisone. The objectives of the study were to evaluate efficacy and safety of deflazacort in children with nephrotic syndrome. Eligible Patients were the children with nephrotic syndrome who were treated with deflazacort from October. 1994 to April. 1999. Nephrotic syndrome was defined as having albumin level of less than 2.5 mg/dL and 24-hour urinary protein excretion of greater than $40\;mg/m^2/hr$. The primary parameters evaluating the efficacy of deflazacort were response rate, time to respond and relapse frequency. The safety profiles were the impact on children's growth, calcium sparing effect, glucose metabolism, lipid profile and adverse drug reactions. As results, total of 60 children were evaluated (47 boys, 13 girls). Response rate was $95\%$ (57/60) for initial and late responders. Median time to respond was 12 days (range 7-110 days) and median relapse frequency was one time (range 0-6). Weight/height ratio increased from $22.05\pm3.47\;to\23.20\pm3.44\;kg/m$ (p<0.001) and plasma calcium level, from $7.55\pm3.86\;to\;9.98\pm3.77\;mg/dL$ after treatment (p<0.001). Change of fasting glucose level was not statistically significant $(91.92\pm3.53\;vs.\;98.19\pm4.78\;mg/dL,\;p=0.072)$, while change of total cholesterol was significant $(362.3\pm12.0\;vs\;251.4\pm11.5\;mg/dL$, p<0.001). In conclusion, patients on deflazacort showed similar efficacy in treatment of nephrotic syndrome as reported for prednisone with less impact on growth inhibition and metabolic side effects of hyperglycemia and hyperlipidemia.

Purpose: The aim of this study is to examine the tolerability and effect of early high-dose amino acid administration in extremely low birth weight infants (ELBWIs). Methods: This retrospective cohort study included ELBWI (birth weight <1,000 g, n=142). Biochemical, nutritional, and neurodevelopmental data were compared between infants who received conventional low amino acid (LAA; 1.5 g/kg/day) and those who received high amino acid (HAA; 3 g/kg/day) within the first 48 hours after birth. Neurodevelopmental data included weight, height, and head circumference at discharge, 12 to 14 and 18 to 24 months of corrected age and the Korean Bayley Scale of Infant Development II (K-BSID-II) score at 18 to 24 months of corrected age. Results: The HAA group demonstrated higher peak plasma albumin ($3.0{\pm}0.4$ vs. $3.2{\pm}0.5$, P<0.05) and lower serum creatinine ($1.7{\pm}0.9$ vs. $1.4{\pm}0.8$, P<0.05) during the first 14 days than the LAA group. Full enteral feeding was achieved significantly earlier in infants in the HAA group than in infants in the LAA group ($46.2{\pm}23.0days$ vs. $34.3{\pm}21days$, P<0.01). There was no difference between the two groups in the z score changes in all growth indicators from birth to discharge and at 12 to 14 and 18 to 24 months of corrected age, as well as in the K-BSID-II score at 18 to 24 months of corrected age. Conclusion: Aggressive administration of amino acids during the first 2 days of life in ELBWI was well tolerated and correlated with earlier full enteral feeding, but did not improve growth and neurodevelopment.

Objective: Present study was designed to evaluate the efficacy of Acacia nilotica bark extract as an alternative to antibiotic growth promoters in broilers. Methods: Six hundred, day-old broiler chicks were randomly divided into six groups (NC, without any supplementation; AB, NC+Zinc Bacitracin; PB, NC+Safmannan; ANBE1, NC+A. nilotica bark extract 0.1%; ANBE3, NC+A. nilotica bark extract 0.3%; ANBE5, NC+A. nilotica bark extract 0.5%), with ten replicates per group (10 chicks/replicate) and feeding trial was lasted for 35 days. Results: Results showed that weight gain (1,296.63 g) and feed conversion ratio (FCR, 1.59) of AB was better than NC, during the finisher phase. Overall FCR of AB (1.53), PB (1.54), and ANBE5 (1.54) was significantly (p<0.05) better than NC. From carcass parameters relative weight of wing and heart were highest in ANBE3 (2.5% and 1.51%, respectively). Significantly (p<0.05) highest blood glucose level was observed in NC (264.5 mg/dL) and highest albumin concentration was found in AB (1.46 mg/dL). In addition, antibody titer levels against ND and IBD were higher in ANBE5 than NC, while higher relative weight of bursa was observed in ANBE3 than NC. The villus height to crypt depth ratio in all experimental groups was better than NC. Conclusion: Acacia nilotica bark extract could be a suitable alternative to antibiotic growth promoters to support the growth in broilers.

Objective: The objective of this study was to investigate the effect of supplementation with enzymolytic soybean meal (ESBM) on broilers fed low crude protein (CP) diets. Methods: A total of 360 one-day-old broilers were randomly assigned to six treatments with 6 replicates per treatment and 10 chicks per replicate for a period of 42 days. Chicks were fed a basal standard high-CP diet as a positive control (PC), a low-CP diet (reducing 10 g/kg CP from the PC) as a negative control (NC), or an NC + 0.5%, 1.0%, 1.5%, or 2.0% ESBM diet. Results: Compared to chicks fed the PC, chicks fed the NC had a decreased body weight gain (BWG, p<0.05) from 1 to 42 days, but supplementation with 2.0% ESBM restored BWG (p<0.05) and even linearly improved the feed conversion rate (FCR, p<0.05). Digestibility of CP and ether extract was increased (p<0.05) in chicks fed a 1.0% ESBM diet compared to the PC. With increasing levels of ESBM, nitrogen (N) excretion decreased (p<0.05). The addition of ESBM to the diet did not affect (p>0.05) serum concentrations of total protein, albumin and total cholesterol but led to a descending trend in triglycerides and an ascending trend in calcium and urea N at 42 days (p<0.10). There were no differences (p>0.05) in villus height (VH), crypt depth (CD), and VH/CD (V/C) of the duodenum and jejunum between the PC and NC at both 21 days and 42 days, while increasing dietary ESBM levels linearly (p<0.05) decreased CD and increased V/C of the duodenum and jejunum at both 21 days and 42 days. Conclusion: The findings indicated that ESBM could be used in broiler low-CP diets to improve production performance, decrease N excretion, and enhance intestinal health.

Objective: This study was conducted to evaluate the effects of tannins and cellulase on growth performance, nutrient digestibility, blood profiles, intestinal morphology, and carcass characteristics in Hu sheep. Methods: A total of 48 three-month-old meat Hu sheep ($25.05{\pm}0.9kg$) were blocked based on body weight, and randomly allotted to 4 treatments with 3 replicates of 4 sheep each. The experiment lasted for 80 d, and dietary treatments were as follows: i) CON, control diet; ii) TAN, CON+0.1% tannins; iii) CEL, CON+0.1% cellulase; iv) TAN+CEL, CON+0.1% tannins and 0.1% cellulase. Results: Compared with CON, CEL, and TAN+CEL had greater (p<0.05) final body weight (FBW) and average daily gain but lower (p<0.05) feed conversion ratio, while FBW of TAN+CEL was lower (p<0.05) than that of CEL. The apparent total tract digestibility (ATTD) of dry matter in TAN, CEL, and TAN+CEL groups were higher (p<0.05) than that in CON. CEL and TAN+CEL groups had greater (p<0.05) ATTD of crude fiber compared with TAN and CON, while TAN group had lower (p<0.05) ATTD of crude protein than other treatments. TAN, CEL, and TAN+CEL groups increased (p<0.05) serum globulin and alkaline phosphatase but decreased (p<0.05) albumin/globulin. Serum total protein was greatest for TAN+CEL, intermediate for TAN and CEL and least for CON (p<0.05). TAN+CEL group increased (p<0.05) dressing percentage compared with CON, while the backfat thickness of CEL was lower (p<0.05) than that of CON. The villus height of jejunum and ileum in CEL and TAN+CEL groups were greater (p<0.05) than that in CON, and the crypt depth and villus height: crypt depth of jejunum were increased (p<0.05) in TAN, CEL, and TAN+CEL groups. Conclusion: The addition of tannins and cellulase together promoted nutrient digestion, liver protein synthesis and intestinal development and thus improved growth performance and carcass characteristics.

The purpose of this study is to investigate initial nutritional status of stomach cancer patients. The study subjects were 88 patients with stomach cancer admitted at Kosin University Gospel Hospital in Busan. We assessed the initial nutritional status by anthropometric, biochemical and dietary intake data along with subjective global assessment(SGA). The results are as follows. 1. The mean age, weight, height, triceps skinfold thickness, mid arm circumference, and mid arm muscle circumference of the subjects were 55.9$\pm$11.0years, 60.0$\pm$9.8kg, 162.4$\pm$8.5cm, 10.9$\pm$5.7mm, 26.8$\pm$3.8cm, and 23.4$\pm$3.5cm respectively. The mean body mass index was within the normal range, with 22.7$\pm$2.8kg/m2, while 15.4% of the patients was underweight. The result shows that body fat mass and body protein mass of the patients with stomach cancer were decreased. 2. The mean biochemical data of the subjects were 4.0$\pm$0.5g/dl for albumin, 174.7$\pm$41.9mg/dl for cholesterol, 107.6$\pm$57.2mg/dl for triglyceride, 92.1μg/dl for Zn, 　297.0$\pm$103.1mg/dl for transferrin, 1980.0$\pm$0.8$mm^3$ for total lymphocyte count. 3. Daily energy intake was 1997.8$\pm$579.3kcal. And the ratio of carbohydrate, protein, and lipid to energy intake was 72:14:14. 4. The patients were divided into three groups according to SGA performed by an observer. Group A(well nourished) was 55.7% with 49 patients, Group B(moderately malnourished) was 22.7 % with 20 patients, and Group C(severely malnourished) was 21.6 % with 19 patients. The three groups showed a significant difference in body weight(p<0.01), 1 month weight loss %(p<0.001), 6 months weight loss %(p<0.001), body mass index(p<0.01), and mid arm circumference(p<0.05), albumin(p<0.01), energy intake(p<0.05) as well as carbohydrate intake(p<0.05). From these results, it may be concluded that SGA can be used as a nutrition screening tool, and comprehensive nutrition assessment is desirable for those malnourished.
