Purpose : The aim of this study was to determine the reference ranges of serum albumin levels depending on the gestational ages of preterm infants. We also intended to compare the mean serum albumin levels between groups of preterm infants that did not develop clinical disorders later, and groups that did develop clinical disorders such as respiratory distress syndrome, intraventricular hemorrhage, retinopathy of prematurity, apnea and bronchopulmonary dysplasia. We also examined the significance of serum albumin as a predictor for the development of clinical disorders. Methods : The records of 208 neonates with gestational ages from 23 weeks to 41 weeks were reviewed retrospectively. The mean albumin concentrations with reference ranges by gestational ages were determined. Statistics for each two of group were compared. Logistic regression analysis was used to model odd ratio, and 95 percent confidence interval as a mean of the association between predictors and outcome. Results : Serum albumin levels were at 23-24 weeks gestation was 2.36 g/dL, rising to 3.43 g/dL in full term babies. There were significant mean differences between the clinical groups and control groups for each clinical disorder such as respiratory distress syndrome, intraventricular hemorrhage, retinopathy of prematurity and apnea in premature babies of 30-36 weeks of gestation. Low serum albumin appeared to be associated with increased risks of clinical disorders. Conclusion : The normal serum albumin levels in preterm infants should be defined according to the gestational ages. Lower albumin levels increase the risks of the later development of clinical disorders, which are common in premature infants.

We report that the gamma linolenic acid content of pork is higher in finishing pigs fed diets containing hemp seed oil, evening primrose oil or borage oil as the sources of gamma linolenic acid. Thirty-six three crossing swines ($Landrace{\times}Yorkshire{\times}Duroc$), 80 kg in body weight, were randomly separated into four treatment groups with three pens per treatment and three animals per pen. The finishing swines were fed the experimental diets for 35 days until they reached the market weight of 110 kg. The animals were assigned to the four experimental diets: control diet containing 5.00% tallow, T1 containing 5.00% hemp seed oil (hemp seed oil 40:soybean oil 60), T2 containing 5.00% evening primrose oil (primrose oil 40:soybean oil 60) and T3 containing 5.00% borage oil (borage oil 40:soybean oil 60). The plasma triacylglycerol and total cholesterol content of the swine in the gamma fatty acids-fed groups were significantly (p<0.05) lower than those in the control group. No gamma linolenic acid was detected in the plasma of the control group, while tile level of gamma linolenic acid treatment groups was significantly (p<0.05) higher than the control in the order of T3, T2 and T1. Moreover, the level of gamma linolenic acid increased with increasing number of feeding days. There was a significant difference between the treatment groups (p<0.05). There was a difference in the amount of saturated fatty acid and polyunsaturated fatty acid accumulated in the pork according to the treatment groups or the parts of the pork meat. The level of n-3 fatty acid of pork was highest in T1, which had been fed the hemp seed oil, followed in order by T3 and T2 (p<0.05). The content of gamma linolenic acid in pork was highest in T3, which had been fed the borage oil, followed in order by T2 and T1 (p<0.05). In particular, the level of gamma linolenic acid in pork increased in the order of the back fat, pork belly, ham and loin.

Objectives : This study aimed to investigate the association between depression with atypical features and metabolic syndromes in Korean adults using the 2016 Korean National Health and Nutrition Examination Survey (KNHANES) data. Methods : We used the 2016 KNHANES data to enroll 277 participants with a score of 10 or higher on Patient Health Questionnaire-9. Depression with atypical features was diagnosed when at least two of the following criteria were met : 1) sleeping more than 10 hours a day ; 2) weight gain of more than 3 kg in a year ; and 3) fatigue/anergia. Depression was divided into two groups based on the presence/absence of atypical features. Physical and mental health, and risk of metabolic syndrome were compared between the groups. Results : Among the 277 participants, 91 had depression with atypical features. We identified significant differences in age, sex, income, and education between the two groups. After adjusting for these variables, depression with atypical features had lower EuroQol-5D index scores (p<0.001) and higher prevalence of metabolic syndromes (p=0.035) compared to the depression without atypical features. Depression with atypical features had higher odds ratio (OR) in association with metabolic syndromes after adjusting for confounding variables (OR=1.923 ; 95% confidence interval : 1.069-3.460). Conclusions : Depression with atypical features increases the risk of metabolic syndromes and lowers the quality of life.

Objectives: The aim of this study was to assess how nutrient intakes are related to risk factors for metabolic syndrome according to dietary patterns in the middle-aged adults. Methods: The subjects (n = 187; 47 men, 140 women) consisted of middle-aged adults over 30 years old in Ilsan area. The metabolic syndrome was diagnosed according to the data collected from each subject, including anthropometric measurements and blood analyses. The dietary patterns were derived from the average of two-day dietary intake data. Results: Factor analysis identified three major dietary patterns which were "Meats and alcohol", "Mixed grains, vegetables and fruits", and "Rice, Kimchi and fish & shellfish". The daily intakes of energy, protein, and sodium increased across quartiles of "Meats and alcohol" pattern scores (p < 0.05), whereas the intakes of carbohydrates, potassium, calcium, and fiber increased across quartiles of "Mixed grains, vegetables and fruits" pattern scores (p < 0.001). The "Meats and alcohol" pattern scores were positively correlated with protein and sodium intakes but inversely correlated with carbohydrates, fiber and potassium intakes which were adjusted for age, sex and energy (p < 0.05). The highest quartile pattern score of "Meats and alcohol" pattern had elevated odds ratio of abdominal obesity and metabolic syndrome (p < 0.05). The risk of hypertriglyceridemia decreased in the highest quartile of "Mixed grains, vegetables and fruits" pattern (OR 0.35, 95% CI 0.12-1.00). Conclusions: Our results suggested that reducing the consumption of meat and alcohol along with increasing fruits, vegetables and mixed grains would be helpful for preventing the metabolic syndrome and chronic diseases.

This work was designed as basic studies on the development of diet for the treatment of obesity. The effect of alginic acid which is the major component of brown algae was investigated by comparing with agar, cellulose, carboxymethylcellulose (CMC), chitin, and lignin as dietary fibers. These dietary fibers ($10\%$) supplemented to basic diet were fed ad libitum to Sprague Dawley rat for 4 weeks, and the inhibitory effects on obesity were evaluated by measuring body weight gain and feed efficiency, the content of glucose and cholesterol in serum, lipase activity in serum, lipid content in liver, adipose tissue around epididymis and ovarium, and Lee index etc. Among the inhibitory effect of these dietary fibers on obesity, lignin was the most effective (p<0.001), followed by Na-alginate (p<0.01) for body weight gain, but lignin was the most effective, followed by CMC, and followed by Na-alginate for feed efficiency (p<0.001). In the inhibitory effects on lipid accumulation in liver and adipose tissue around epididymis and ovarium, lignin and Na-alginate group among these dietary fibers were more effective than others, but there was no significant difference between male and female. The inhibitory effect on obesity evaluated by Lee index was effective in the order of Na-alginate>lignin>CMC>chitin>cellulose (p<0.001). The decreasing effects of lipid content in liver by dietary fibers were found in the order of agar>CMC>cellulose>Na-alginate>chitin>lignin (p<0.001). Glucose content in serum was significantly decreased in cases of CMC, lignin and Na-alginate, whereas a slight difference was found in chitin, but cholesterol content in serum was decreased for all dietary fibers examined except cellulose group. The increasing effect of lipase activity in plasma was found in cases of Na-alginate and chitin, while cellulose, CMC and lignin groups were decreased.

This study was conducted to investigate the effects of dietary herbal plant mixture on growth performance, blood immunological parameters, fecal VFA and NH3-N concentrations in growing pigs. The dietary treatments were 1) NC (negative control; antibiotics-free diet), 2) PC (positive control; NC diet added 0.16% antibiotic), 3) NCK0.2 (NC diet added 0.2% herbal plant mixture (koppuul??)) and 4) PCK0.1 (PC diet added 0.1% herbal plant mixture (koppuul??)). Eighty crossbred (Landrace×Yorkshire×Duroc) pigs (16.35±0.05kg average initial body weight) were used for 42 days. The pigs were assigned to the treatments according to body weight and each treatment had 5 replicates of 4 pigs per pen in a randomized complete block design. During the whole experimental period, PCK0.1 and PC treatments had significantly higher ADG than NC treatment (P<0.05). Gain/feed of pigs fed PC diet was higher than that of pigs fed NC diet (P<0.05). For blood immunological parameters investigations, white blood cells (WBC) counts and IgG level increased in the pigs fed PC, NCK0.2 and PCK0.1 diets compared to pigs fed NC diet. In addition, higher (P<0.05) serum lymphocyte concentration was found in PCK0.1 treatment compared to NC treatment. NH3-N concentration in pigs fed NCK0.2% diet was lower than that in pigs fed PC and NC diets. There were no significant differences in DM and N digestibilities among the treatments. In conclusion, the results suggested that the dietary additions of herbal plant mixture or antibiotics increase ADG, the concentrations of WBC counts and IgG, lymphocyte, while decrease NH3-N concentration in feces.

Twenty eight Holstein steers 12 months old and weighing about 300kg were andomly allotted into one of four groups being fed ammoniated rice straw(ARS) and substituted 30%, 40% and 50% crushed bamboo chip for ARS to determine the effects of different levels of bamboo chip on performance, digestibility and carcass characteristics. Daily weight gain was reduced as the substitution levels of bamboo chip for ARS as a roughage source increased but there were no differences in daily weight gain between steers fed ARS alone and 30% bamboo chip for ARS. Concentrates intakes were not different between treatments by the substitution levels of bamboo chip for the whole fattening period. Roughage intake tended to increase as the substitution levels of bamboo chip increased. Total feed intake was not affected by the substitution levels of bamboo chip. However, feed efficiency got worse with increasing levels of bamboo chip. Animals fed the roughage substituting 30% bamboo chip for ARS were higher in profit by 13% than animals fed ARS alone as a roughage source. Digestibilities of Dry matter(DDM) and crude fiber(DCF) were highest in animals fed ARS alone as a roughage source. DDM's were lower in higher substitution levels of crushed bamboo chip but there were no differences in DCF among animals fed different levels of bamboo chip as a roughage source. Crude protein digestibility was not affected by ammoniated rice straw or by the different levels of bamboo chip. Dressing percentage and backfat thickness were not affected by ammoniated rice straw or by the levels of bamboo chip but ribeye area was narrowed as the levels of bamboo chip increased. Beef color, fat color, texture, maturity and marbling score were not affected by feeding of ammoniated rice straw or by the levels of bamboo chip. According to these results, it may be concluded that profit can increase when Holstein bulls are castrated and roughage containing ammoniated rice straw plus 30% bamboo chip is offered.

The objective of the present study was to investigate the effect of dietary supplementation of the ginseng by-product on growth performance and meat quality in finishing pigs. The animals used in the experiment were a total of 24 Landrace×Yorkshire and weighted 65.81±2.02kg. The experimental diets were basal diet(CON) and 2.5% ginseng by-product(GBP), which replaced lupin in basal diet. The pigs were allotted at 4 pigs per pen with three replicate pens per treatment by completely randomized design. In growth performance, ADFI was significantly lower(P<0.0001) in GBP than in CON. In plasma biochemical composition, total protein(P<0.01), blood urea nitrogen(P<0.03), glucose(P<0.01), albumin(P<0.02), calcium(P<0.01) and inorganic phosphate(P<0.01) were significantly higher in GBP than in CON. Carcass and meat quality were not significantly different between treatments. Total ginsenoside content on meat was significantly higher(P<0.0001) in GBP than in CON. TBARs was significantly lower in GBP than in CON for 6 days(P<0.03) and 12 days (P<0.06), respectively. Our research indicates that plasma biochemical composition, total ginsenoside content and TBARs were affected when replaced with ginseng by-product. Ginseng by-product in the pig diet increased pig muscle ginsenoside, indicating that ginseng by-product can be used as a feed additive.

An experiment was conducted to investigate the effects of dietary supplementation of a silicate mineral (D Lite) on growth performance, nutrient retention, carcass characteristics and meat quality in broiler chicks. A total of 640 broiler chicks were randomly allotted to four dietary treatments in a randomized complete block design. Each treatment had four replicates comprising 40 broilers in each replicate. Dietary treatments were as follows: control (0% D Lite), and diets supplemented with 0.15%, 0.30% and 0.45% of D Lite. The starter and finisher diets were fed from d 0 to 21 and d 21 to 35, respectively. Body weight gain during starter (p<0.05), finisher (p=0.057) and overall (p<0.001) experimental period and feed intake (p<0.05) during starter period decreased quadratically with increasing dietary D Lite levels. The birds fed 0.15% D Lite showed the greatest (p<0.05) overall weight gain, feed intake and retention of gross energy and calcium. There were no differences (p>0.05) in carcass characteristics, organ weights and breast meat composition. However, as the level of D Lite was increased in the diet there was a linear decrease in the TBARS values of breast meat (p<0.05) at d 12 of storage. These results suggest that D Lite supplementation at the level of 0.15% is shown to be effective in improving performance and nutrient retention in broilers.

Purpose : This study was performed to evaluate survival, failure patterns, and prognostic factors of MMR patients after radiation therapy. We also discussed the need for chemotherapy. Materials and Methods : A retrospective analysis was done for 23 patients with MMR who were treated with radiation therapy from June 1985 to November 1992. There were 19 male and 4 female patients, The patients' age ranged from 17 to 71 years (median 39 years). Systemic symptoms including fever, weight loss, or malaise were found in $30\%$ of the patients. The nasal cavity was most frequently involved No patients had nodal involvement at diagnosis. There were 2 patients with distant metastasis at presentation. Radiation therapy was delivered five times a week, 1.8 Gy daily, total $45\~54$ Gy (median 50.4 Gy) using 6 MV X-ray No patients received chemotherapy as initial treatment. Results : Overall 5-year and 10-year survival rates were $52.4\%$ and $44.1\%$, respectively. Seventy Percent(12/17) of the patients achieved complete response to radiotherapy, and $29.4\%$ (5/17) achieved partial response. The Patients with complete response showed a better 5-year survival rate than those with partial response ($66.9\%$ vs. $20\%$. p=0.004). Symptom duration before diagnosis, the presence of systemic symptom, and the number of primary sites had no influence on survival. The patterns of failure were as follows: local failure(1), failure in adjacent site(1), local and distant failure(1) distant metastasis(2). and conversion to malignant lymphoma(1). We could not find factors associated with the patterns of failure. Conclusion : The most important facto associated with survival was the response to radiotherapy. Seventeen percent of the patients had distant metastasis, and the salvage after distant metastasis was not successful. However. about $50\%$ of the patients could achieve long-term survival with local radiation therapy alone. Therefore, chemotherapy of MMR should be done after a prospective randomized study for the factors associated with distant metastasis.
