Two experiments were conducted to search factor(s) affecting the plasma allantoin concentration in infant calves. In experiment 1, five male Holstein calves aged 1 week were given only milk replacer free from nucleic acids for 28 days Plasma allantoin concentration varied in a reverse proportion to daily amounts of milk replacer, and the concentration when calves received 750 g/d of milk replacer was significantly lower than that when they received 250 g/d. Contrary to plasma allantoin concentration, glomerular filtration rate(GFR) was directly proportional to daily amounts of milk replacer, leading to a constant filtration of allantoin across the glomeruli. Renal handling of allantion was also unaffected by the amount of milk replacer, resulting in the constant urinary excretion of allantoin. These results suggested that GFR, which was affected by the nutritional status, could affect plasma allantoin concentration. In experiment 2, the effect of age-related changes in nutritional status after weaning on GFR was examined in eight calves weaned at 5 weeks of age. The GFR expressed as body weight basis was lower immediately after weaning, but linearly increased up to the 19th week post-weaning. The present results suggested that the changes in GFR in response to nutritional status would be one of the possible causes of atypical plasma allantoin concentration immediately after weaning. We conclude that plasma allantoin concentration would not be a proper estimator of intestinal flow of microbial protein in cattle.

The prognosis of maintenance hemodialysis (HD) patients is closely related to their nutritional status. It is important to develop and use of a reliable, useful and easy method of nutritional assessment scale for evaluation of nutritional status and progression of the patients. This study was initiated to evaluate the clinical usefulness of Instant Nutritional Assessment Scale(INAS) by cross-sectional and longitudinal studies. One hundred HD patients entered a continuing nutritional study and followed for 1 year. The results were as follow ; 1. 24% of patients was normal to mild, 43% was moderate and 33% was severe deficit of nutritional status. 2. The mean INAS score of the patients was 8.00(S. D.=2.83), and there didn't reveal any differences in INAS score by general characteristics. The mean transferrin score was 1.98, whih was the highest of 5 nutirtional parameters of INAS. Only 7 patients had within nomal range of transferrin concentration. 3. Within one year since this study was initiated, 10 patients died. Six of them were with severe deficit and one of them was normal to mild deficit groups. The death rate in severe deficit group was higher than that of normal to mild deficit group (P=.0640). 4. Occurrence of acute complication during HD in severe deficit guoup was higher than that of normal to mild deficit group(P=.001). 5. The number of consultation to the doctor and hospital admission in severe deficit group was higher than that of normal to mild deficit group(P=.0001). 6. INAS score was significantly correlated with occurrence of acute complications during HD and the number of consultation to the doctor. In conclusion, INAS based on the levels of body mass index, midarm circumference, triceps skinfold thickness, transferrin concentration and total lymphocyte count seems to be a reliable predictive nutritional index for prognosis. So nurses are encouraged to adopt INAS in care of the chronically illed patients. Recommendations for further research was suggested.

The purposes of this study are to evaluate nutritional status and dietary intake of vitamin A in 5th and 6th grade primary school children in Chungbuk. Also the relationships between nutritional status and factors relevant to dietary intake of vitamin A were examined. For the study, total 180 children in urban area of Chongju city(37 boys and 40 girls) and rural area of Eumsong gun(56 boys and 47 girls) were recruited. For the assessment of dietary nutrients intake including vitamin A, 1-day, 24-hr recall method was applied. And serum retinol contents were analyzed by HPLC to diagnose the nutritional status of vitamin A. The average of daily vitamin A intake was 490R.E., 81.8% of RDA. Vitamin A intake of urban was higher than that of rural children(p < 0.001). Of the total dietary vitamin A intake, only 25.8% came from animal retinol, means that children still heavily depend on plant carotenoids as vitamin A floods. The average serum retinol concentration of total 180 children was 37.2$\mu\textrm{g}$/100ml. Serum retinol concentration of urban children was 37.3$\mu\textrm{g}$/100m1, significantly higher than rural children of 35.6$\mu\textrm{g}$/100m1(p < 0.05). According to the biochemical criteria, no one was in critical vitamin A nutritional status. Because of relatively large day-to-day vitamin A intake, 1-day, 24-hr recall method may not be the proper way to assess the usual intake of vitamin A. In conclusion , to diagnose the nutritional status of vitamin A by dietary survey, it is necessary to develop new survey technique which measure the dietary habit of the people.

Observations were made on the total serum protein values of 532 Korean cattles(341 females and 191 males and 191 males) and 90 milk cows in order to determine the effects of age, sex and nutritional status upon serum protein. Results obtained in this studies were summerized as follows; 1. The concentration of total serum protein was higher in the adult than in the younger and was generally increased with the advance of age in Korean cattle. The rate of increase in total serum protein content was more significant in the young than that of adult. 2. The average concentration of total serum protein of male did not differ significaltly from that of females in Korean cattle. 3. The concentration of total serum protein in milk cows were significaltly higher than that of Korean cattle cows and this difference seemed to be influenced by rations high in protein 4. A general tendency showed that the concentration of total serum protein was significaltly higher in the Korean cattle keeping with good nutritional status than that of poor nutritional status.

The present study was conducted to investigate the effects of beverages containing fermented Akebia quinata extracts on alcoholic hangover. For this study, 25 healthy young men were recruited. All participants consumed 100 mL of water (placebo), commercial hangover beverage A or B, fermented A. quinata leaf (AQL) or fruit (AQF) extract before alcohol consumption. After 1 h, all participants consumed a bottle of Soju, Korean distilled liquor (360 mL), containing 20% alcohol. Blood was collected at 0 h, 1 h, 3 h, and 5 h after alcohol consumption. The plasma alanine transaminase (ALT) activity was highest in the placebo group. Compared with the control group, the AQL and AQF groups showed decreased ALT activity at 5 h after alcohol consumption. Plasma ethanol concentration was increased after alcohol intake and peaked at 3 h after alcohol consumption. Compared with the control group, the A group showed a higher plasma ethanol concentration at 1 h (P<0.05). At 3 h after alcohol consumption, the AQF group showed the lowest mean plasma ethanol concentration compared to the other groups; however, there were no statistical differences. After 5 h of alcohol consumption, the AQL and AQF groups showed lower plasma ethanol concentrations compared with the B group. The sensory evaluation score for the fermented A. quinata fruit extract was lower than for the commercial hangover beverages. In conclusion, the present intervention study results suggest that fermented A. quinata extracts alleviate alcoholic hangover and reduce plasma ethanol concentrations.

BACKGROUND/OBJECTIVES: Concerns about regional disparities in heathy eating and nutritional status among South Korean adults are increasing. This study aims to identify the magnitude of regional disparities in diet and nutritional status among Korean adults who completed the 2017 Korea National Health and Nutrition Examination Survey (KNHANES). SUBJECTS/METHODS: The participants were a nationally representative sample of Korean adults aged 19 years and older from the 2017 KNHANES (n = 6,126). We employed the svy commands in STATA to accommodate the complex survey design. The relative concentration index (RCI), absolute concentration index (ACI) and index of disparity were used to measure regional nutritional inequalities. RESULTS: Overweight and obese adults were more prevalent among the poor than among the rich in urban areas (RCI = -0.041; P < 0.05), while overweight and obese adults were more prevalent among the rich than among the poor in rural areas of South Korea (RCI = 0.084; P < 0.05). Economic inequality in fruit and vegetable intake ≥ 500 g per day was greater in rural areas than in urban areas in both relative size (RCI = 0.228 vs. 0.091, difference in equality = 0.137; P < 0.05) and absolute size (ACI = 0.055 vs. 0.023, difference in equality = 0.032; P < 0.05). CONCLUSIONS: This study provides useful information identifying opposite directions in the relative concentration curves between urban and rural areas. Adult overweight/obesity was more prevalent among the poor in urban areas, while adult overweight/obesity was more prevalent among the rich in rural areas. Public health nutrition systems should be implemented to identify nutritional inequalities that should be targeted across regions in South Korea.

Insufficient dietary intake of vitamin A is one of the major nutritional problems for elderly adults in some parts of Korea. The objective of this study was to determine the vitamin A nutritional status of elderly adults in Asan, Korea by assessing the dietary intake and serum retinol concentration. Five hundred twenty four subjects (218 male and 306 female) over 65 years were recruited from city of Asan. Each subject was interviewed to assess the intake of vitamin A using a 24hr recall method and data were analysed from computer-aided nutrient analysis program. Blood samples after 12hr fasting were collected for serum retinol concentration and reverse phased HPLC with UV detector used. The results showed that subjects did not consume the sufficient amount of energy (82-85% of Korean RDA for male and 77-79% RDA for female) and vitamin A (59% RDA for male and 50% RDA for female). Range for retinol intake was 0 to $4342\;{\mu}g$ a day while that of beta-carotene was 65 to $31595\;{\mu}g$. Serum retinol concentrations were within a normal range for both male ($80\;{\mu}g/dl$) and female ($67\;{\mu}g/dl$) subjects. Many subjects (n=342) consumed less than 50% RDA of vitamin A. However, if retinol intake was high (> $37\;{\mu}g$), even with less than 50% RDA of vitamin A intake, serum retinol concentration was high ($75\;{\mu}g/dl$). Subjects showed normal serum retinol status even with low vitamin A intake. The results suggested that optimal intake ratio of dietary retinol and carotenoid is important to maintain an appropriate serum retinol concentration.

Long-term hemodialysis(HD) patients manifest various signs of protein and caloric malutrition due to poor intake of nutrients and other causes. Poor nutritional status increases the mortality and morbidity rates in HD patients. Thus, mataintnance of adequate nutritional status has been a major task in taking care of patients receiving HD. This study was to evaluate the nutritional status of HD patients and to clarify the degree of nutritional deficit based on usual dietary intake, anthropometric and biochemical indicators. Sixty HD patients comprised a HD group, while the control group consisted of 60 healthy adults whose age and sex matched those of the HD group. Nutritional status was evaluated by dietrary intake using instant nutritional scale, anthropometric measures, serum protein concentrations and the number of lymphocytes. The data were analyzed by using Chi-square test and unpaired t-test. The results are as follows. 1. Regarding usual dietary intake of HD group. 1) Estimated caloric intake was significantly lower than the recommended daily allowance(RDA) and among them, 35% were taking calories less than 85% of the RDA. 2) Estimated protein intake was significantly higher than the RDA and among them 40% were taking protein more than 115% of the RDA. 3) Estimated fat intake was lower than the RDA. 4) Vitamin A, B, $B_1,\;B_2$, C and niacin in take was lower than the RDA respectively. 5) Estimated ferrous intake was within the normal limit the RDA while estimated calcium intake was higher than the RDA. 6) Both calorie and protein intake were higher for the 10 patients who had been under continuous ambulatory peritoneal dialysis than for the patients under HD from the beginning. 2. Regarding anthropometric measures : 1) Body mass index(BMI), midarm circumference(MAC), and triceps skinfold thickness(TSF) were lower in the HD group than in the control group. 2) Among HD group, 47.1% were within the normal limit of BMI, while 86.7% were within the same limit in the control group. 3) Among HD group, 35.0% were within the normal limit of MAC, while 83.3% were within the same limit in the control group. 4) Among HD group, only 8.3% were normal, 30.3% were mild deficit status of TSF, while 50% were normal and 48.3% were mild deficit status in the control group. 3. Regarding biochemical laboratory tests 1) Albumin, transferrin concentrations and the number of lymphocytes were lower in HD group than in the control group. 2) Among HD group, 98.3% were within the normal limit of albumin concentration and all were within the same limit in the control group. 3) Among HD group, only 11.7% were within the normal limit of transferrin concentration, while 81.7% were within the same limit in the control group. 4) Among HD group, 25% were within the normal limit, while 93.3% were within the same limit in the control group. The above findings suggest that HD patients were in nutritional deficit status. Adequate diet therapy and periodical evaluation of the nutritional status in HD patients are needed. Accordingly, it turned out that anthropometric measures were very reliable parameters and easy to use to evaluate nutritional status. So nurses are encouraged to adopt anthropometric measures to examine nutritional deficit status of HD patients.

BACKGROUND/OBJECTIVES: The elderly are reported to have a high prevalence of nutritional anemia when they have lower intakes of nutrients or chronic diseases. This study was conducted to compare nutritional status according to nutritional anemia and to determine associations between nutritional anemia and chronic diseases in Korean elderly. SUBJECTS/METHODS: This study utilized data on 3,258 elderly aged ${\geq}65$ years gathered during the $6^{th}$ Korea National Health and Nutrition Examination Survey 2013-2015. Subjects were divided into nutritional anemia (NA) group (n = 415) and non-NA group (n = 2,843) by hemoglobin concentration. Nutrient intakes were assessed using dietary intake data obtained using the 24-hour recall method. The odds ratios (ORs) for nutritional anemia by chronic diseases were determined. Statistical analysis was performed using SPSS Ver. 23.0. RESULTS: Of 3,258 subjects, 12.7% had nutritional anemia. Intakes of potatoes, pulses, and mushrooms by males and potatoes, fruits, meats, eggs, and seafood by females were significantly lower in NA group than in non-NA group. The proportion of the subjects whose intakes of protein, vitamin A, vitamin $B_1$, vitamin $B_2$, niacin, and iron less than estimated average requirement (EAR) were significantly higher in NA group compared to non-NA group. After adjusting for age, the number of family members, energy intake, and alcohol drinking, ORs for nutritional anemia in the subjects with diabetes and myocardial infarction or angina pectoris were significantly higher by 1.74 times and 1.59 times as compared to the subjects without those diseases, respectively. However, ORs for nutritional anemia in the subjects with obesity, abdominal obesity, and hypertriglyceridemia were significantly lower by 0.64 times, 0.60 times, and 0.59 times as compared to the subjects without those diseases, respectively. CONCLUSIONS: The results of this study suggested that nutritional management should be done to enable the Korean elderly to consume foods with high hematopoietic nutrients density to prevent nutritional anemia. Korean elderly need to make regular efforts to check for nutritional anemia.
