BACKGROUND/OBJECTIVES: Hydrolyzed formula is often fed to infants with gastrointestinal or immune issues, such as malabsorption or cow's milk allergy, because enzymatic treatment has rendered it more digestible and less allergenic than standard cow's milk formula (SF). Partially hydrolyzed formula (PHF) should be considered for those infants who are intolerant to extensively hydrolyzed formula. However, there are concerns about the nutritional insufficiencies of PHF. We aimed to evaluate the effects of PHF on the growth and health indicators in infants who were at high-risk of allergic disease and potential candidates for consuming PHF. SUBJECTS/METHODS: A total of 83 infants aged 0-2 mon with a family history of allergies were assigned to consume either PHF or SF until 24 weeks of age. Anthropometric measures were obtained at baseline, 12 weeks, and 24 weeks; blood samples were drawn and evaluated at the end of the study. RESULTS: No significant differences were observed in weight, height, and weight-for-height at any time point in each sex between the PHF and SF groups. At 24 weeks of age, the weight-for-age and height-for-age z-scores of the SF group were higher than those of the PHF group, but there was no significant difference in the weight-for-height z-score. There were no significant differences in levels of white blood cells, hemoglobin, ferritin, protein, albumin, aspartate aminotransferase, alanine aminotransferase, eosinophil cationic protein, and immunoglobulin E. CONCLUSIONS: In this study, there were no differences in growth and blood panels between the infants consuming PHF or SF. Therefore, infants who are unable to tolerate SF can be fed PHF without nutritional concerns about growth.

This nutrition survey was carried out twice(Spring and autumn) in Sam Chung-Ri, Song Kwang Myun, Soong Ju-Gun. The food intakes of 92 family members were measured by weighing method. Also 45 adults were examined for anthropometric, blood content and blood pressure. The results abtained were summarized as follows; In vegetable foods, the intake of rice was high, but that of legumina and other cereals was low. In animal foods, the intake of milk and eggs was low, and that of oils and fats was very low. However, the food intake between spring and autumn showed remarkable difference. The average intake of calorie, protein, Ca, Fe and vitamin $B_2$ except vitamin $B_1$ and niacin was below the RDAs. The percentage of carbohydrate, protein and fat for energy was 82.2, 11.6 and 6.2%, respectively. The results of anthropometry of height, weight and chestcircumference showed that both sexes Were below Korean Standards. The concentration of Hb & Hct was normal in both sexes, and the rate of anemia was low. The concentrations of plasma glucose, protein, lipids, and blood pressure were normal in both sexes. In case of male, the correlation between plasma albumin and nutrients intake was significant, but the case of female showed different tendency. In case of male, the correlation between weight, height and plasma protein was also significant but the case of female showed different tendency. The rate of parasite infection was very low $(2.17%{\ldots}3.26%)$

The purpose of this study was to investigate Bone Mineral Density(BMD) and affecting factors on BMD of college women in Seoul. The subjects were 47 healthy college women aged 18-25 years. Antrophometric and body fat measurements were performed by Bioelectrical Impedance Fatness Analyzer(Tanita TVF 202). Blood pressure and pulse frequency were measured. Dietary intakes and general living habits were examined through questionnaires and nutrient intakes were analyzed by Computer Aided Nutritional Analysis(CAN) program for professional. Serum total cholesterol, TG(triglyceride), HDL-cholesterol, total protein, albumin, GOT, calcium were measured by Spotchem(SP-4410). Serum osteocalcin and alkaline phosphatase(ALP) were measured to monitor bone formation. BMD of lumbar spine(L2-L4), right hip(neck, ward's triangle, trochanter) and right forearm were measured by Dual Energy X-ray Absorptiometry(DEXA). Muscle strength was measured by examining leg flexion strength(right and left), leg extension power(right and left), handgrip power(right and left) and back strength. All data were statistically analyzed by the SAS PC package program. BMD of college women was normal(by WHO, 1994). Their muscle strength was bad(by national fitness guidebook, 1995). Only a mall number of them exercised (32.6% of subjects). There was no significant difference among BMD, muscle strength and % body fat(p<0.05). There were significant differences between BMD and total cholesterol as well as TG and VLDL-cholesterol(p<0.05). Total cholesterol was associated with decreasing BMD of the right forearm(p<0.05). TG and VLDL-cholesterol are associated with increasing BMD of right hip ward's triangle(p<0.05). There were significant differences among BMD, ALP and serum total protein. ALP was associated with decreasing BMD of the right forearm(p<0.05). There were significant differences between BMD and Ca as well as between Na and K intakes (p<0.05). Intakes of Na and K were associated with decreasing BMD of the right forearm (UD)(p<0.05). There were significant differences between in BMD and pulse frequently and serum albumin (p<0.05). Serum albumin is associated with increasing BMD of L3-L4(p<0.05), right hip neck(p<0.05). %Body fat, TG, VLDL-C, Ca intake, pulse frequency and serum albumin were associated with increasing BMD(p<0.05). Intakes of Na and K, ALP, total cholesterol, total cholesterol, total protein and height are associated with decreasing BMD(p<0.05). Overall results indicate that Ca intake but to be moderate in protein and Na intakes in order to increase BMD. Body exercise was recommended to increase BMD as well.

Changes in nutritional and health status brought on by a two-year balanced diet were assessed with anthropometric measurements as well as hematological and lipid profiles in 56 healthy young men. Recommended dietary allowances (RDA) were adjusted with estimated daily weighted activity factor. The weighted resting energy expenditure factor of the subjects was 2.37 $\pm$ 0.05. Compared with RDA, all nutrient intakes were adequate and 56% of energy was supplied by carbohydrates, 18% by protein and 26% by fat. The vitamin and mineral intakes except vitamin B-2 were higher (26.46-129.88%) than RDA. Vitamin B-2 intake was 92.15 \ulcorner 14.16% of RDA. There was no seasonal variation on nutrient intakes. Height was increased and systolic blood pressure was decreased by balanced diet for two years. Body weight, diastolic blood pressure and body mass index (BMI) were unchanged. The level of hemoglobin and hematocrit was not changed, the level of plasma protein was decreased and the level of plasma total cholesterol and albumin was increased. These results suggest that a balanced diet can increase height and complement health status achieved through vigorous exercise, even in adults, and that the level of Korean RDA for energy is adequate to maintain existing body weight.

This paper describes the simple nanopatterning of proteins on polyelectrolyte surfaces using microcontact printing with a nanopatternable, hydrophilic composite nanomold. The composite nanomold was easily fabricated by blending two UV-curable materials composed of Norland Optical Adhesives(NOA) 63 and poly(ethylene glycol) dimethacrylate(PEG-DMA). NOA 63 provided stable nanostructure formation and PEG-DMA induced high wettability of proteins in the nanomold. Using the composite mold and functionalized surface with polyelectrolytes, the fluorescent, isothiocyanate-tagged, bovine serum albumin(FITC-BSA) was successfully patterned with 8 nm height and 500 nm width. To confirm the feasibility of the protein assay on a nanoscale, a glycoprotein-lectin assay was successfully demonstrated as a model system. As expected, the lectins correctly recognized the nano-patterned glycoproteins such as chicken ovalbumin. The simple preparation of composite nanomold and functionalized surface with a universal platform can be applied to various biomolecules such as DNA, proteins, carbohydrates, and other biomolecules on a nanoscale.

The purpose of this study is to discribe the nutritional status between female collegians on normal diet and lacto-ovo-vegetarian in the child bearing age. Physical examination, hematological parameters(hemoglobin, hematocrit, serum iron, serum albumin)and nutrient intake by dietary survey were carried out on each subject. Serum zinc, iron and copper concentrations were also determined. The results are summarized as follows : 1) Students on normal diet had higher values than lacto-ovo-vegetarian students in the height, weight, and skinfold thickness. 2) Hemoglobin, hematocrit, serum albumin values of the two groups showed no difference. But students on normal diet were higher in the serum irom and copper values than lacto-ovo-vegetarian students. 3) Serum zinc values differed significantly between the vegetarians and non vegetarians (Vegetarians') > non vegetarians') 4) On the nutrient intake of two groups, students on normal diet were higher than lacto-ovo-vegetarian students in the protein but students on normal diet were lower than lacto-ovo-vegetarian students in iron, vitamin A, $vitamin\;B_{2}$, vitamin C and crude fiber. 5) Intakes of calories and protein in the two groups were lower than RDA but Ca, vitamin A, $vitamin\;B_{1}$, $vitamin\;B_{2}$ niacin and vitamin C intakes of the two groups was higher than RDA. 6) Amounts of iron absorbed showed no difference in the two groups. But iron absorption rate was higher in students on normal diet than lacto-ovo-vegetarian students.

The Nutritional Anaemia due to Iron Deficiency is by for the most common variety of anaemia throughout the world, affecting many women in their reproductive years, infant and children. In Korea, several studies reported that most of the female was iron-deficient and anemic. The present study was undertaken to investigate the nutritional anaemic state of the college girls in kwang-ju city area. Seventy-five college girls in child-bearing age (from 17 to 22 years old) were selected and practiced physical examination, hematological and parasitological tests. The results obtained are summarized as follows; 1) The mean body height $(158.6{\pm}3.4cm)$higher tendency compared to other studies, but the mean body weight $(51.1{\pm}5.6kg)$was lighter. 2) The mean red blood cell number was $441.4{\pm}17.7\;10^4/mm^3$, and most of the subjects were included normal criteria. The average hemoglobin level was $12.5{\pm}0.7gm%$, and 25..7% of the subjects was anaemic. (l2gm% below) The average hematocrit value was $39.1{\pm}2.3%$ and 7.0% was anaemic. (below 37%) The average M C.H.C. value was $32.1{\pm}0.9%$, and 86.0% was anaemic. (32% below) These results showed that the incidence of anaemia was high and the anaemia was characterized by hypochromic in general. 3) The mean value of serum total protein and albumin were $6.6{\pm}0.4gm%$ and $4.2{\pm}0.4gm%$. These values were indicated total protein intake was insufficiency, but albumin value was comparatively high. 4) The infestation rate of helminthes was 25.4%, (Ascaris lumbricoides: 20.3%, Trichuris trichiura: 8.5%) and there was no hookworm infected case.

The purpose of this study was to investigate the relationship among calcium intake, blood parameters related with bone metabolism, and serum lipids in healthy adults on self-selected diet. Subjects were consisted of 40 female college students residing in Chungnam. Anthropometric measurements, dietary intake measurements and blood collection were conducted. Serum concentrations of total protein, albumin, alkaline phosphates, leucine amino peptidase, BUN, calcium, inorganic phosphorus, and lipids were measured by biochemical analyzer and ICP spectrometer. The results were as follows. The mean age of subjects was 22.34 years and weight, height and BMI were 52.89kg, 161.29cm and 20.34, respectively. The daily mean energy and calcium intakes were 81.75% and 64.38% of RDA. The mean animal 1:2. The mean serum concentrations were 6.54g/dl(total protein), 4.12g/dl(albumin), 123.24U/(alkaline phosphates), 36.59U/l(leucine amino peptidase), 8.26mg/dl(calcium), 3.29mg/dl(inorganic phosphorus), 60.73mg/dl(triglyceride), 138.49mg/dl(total cholesterol), 65.95mg/dl(HDL-cholesterol), and 60.39mg/dl(LDL-cholesterol). There were no significant differences among calcium intake, bone metabolism parameters, and serum lipids when analyzed by Pearson's correlation coefficient. More systematic studies are required to investigate the roles of calcium in healthy persons on self-selected diets containing different levels of calcium.

The purpose of this survey is to investigate the nutritional status and dietary intake of gastrectomized cancer patients in Asan Medical Center. The subjects were 98 patients, who underwent a gastrectomy due to gastric cancer and were admitted to the General Surgery Department during March 2007 to December 2007. We examined general characteristics (sex, age, clinicopathological stage, type of operation), anthropometric data (height, weight change), biochemical data (red blood cell RBC, hemoglobin HGB, hematocrit HCT, mean corpuscular volume MCV, total lymphocyte count TLC, albumin, total cholesterol), dietary intake and dietary intake related symptoms. Weight loss of gastrectomized patients was $9.0{\pm}4.3$% from preillness weight to visiting out-patient department (OPD) weight. Biochemical data (RBC, HGB, HCT, MCV, TLC, albumin, total cholesterol) significantly deteriorated after gastrectomy. However, outpatient visits were all restored to the normal range. Postoperative energy intake was $785.0{\pm}164.2$ kcal, which corresponds to $41.6{\pm}9.6$% of daily energy requirement. The cause of poor oral intake is mostly fear, abdominal pain and abdominal discomfort. Therefore, to control pre-or post-operative weight change in the future requires, focusing on the body weight to maintain a normal or usual nutrition by interventions and increased caloric intake during hospitalization for the development of nutrient-dense meals. In addition, as the main reason of the lack of intake of meals after the gastrectomy was fear, the patients should be actively encouraged to consider the importance of eating proper meals.
