The purpose of this study was to investigate the relationship and lipids in healthy adults on self-selected diets. These subjects consisted of 40 female college students residing in Chungnam. Anthropometric measure-ments, diet intake measurements, and blood collection were conducted. Serum concentrations of 5 microminerals(As, Cr, Mn, Se, Ni), lipids(triglyceride, total cholesterol, HDL-cholesterol), and glucose were measured by an ICP spectrometer and biochemical analyzer. The results were as follows. The mean age of the subjects was 22.34 years and the mean weight, height, and BMI were 52.89kg, 161.29cm and 20.34, respectively. The mean serum concentrations appeared to be 14.60ug/dl(As), 1.87ug/dl(Cr), 0.18ug/dl(Mn), 23.50ug/dl(Se), 0.21ug/dl(Ni), 60.73mg/dl(triglyceride), 138.49mg/dl(total cholesterol), 65.95mg/dl(HDL-cholesterol), 60.39mg/dl(LDL-cholesterol) and 88.82mg/dl(glucose). When analyzed by Pearson’s correlation coefficient, the serum concentration of Cr was negatively correlated with Ca and vitamin B12 intake(p〈0.05, p〈0.05) respectively, Mn was negatively correlated with Na intake(p〈0.05), Ni, however, was positively correlated with K intake(p〈0.05). The serum concentration of Se was positively correlated with LDL-cholesterol(p〈0.05), Ni, however, negatively correlated with total cholesterol, HDL-cholesterol, LDL-cholesterol, and glucose, respectively(p〈0.001, p〈0.01, p〈0.05). Further studies are needed to clarify the precise micromineral intakes, nutritional assessment of microminerals, and cause-effect relation of microminerals and serum lipids.

The nutritional survey and blood sampling was conducted from May 23 to 27, 1971, in order to investigate the state of the nutritional intake in relation to blood contents of rural women. This survey covered a total of 47 women residing in Youngam-gun, Cholla-namdo, Korea. The daily diet of these subjects was observed by 24-hour recall method and weighing method for 3 days and hemoglobin (Hb), hematocrit(Hct), mean corpuscular hemoglobin concentration (MCHC), serum protein, serum albumin, A/G ratio, serum iron, total iron binding capacity (TIBC), transferrin saturation (TS), serum cholesterol and blood specific gravity (SG) were measured. The results were summarized as follows ; The rate of intake of vegetable foods was high, especially cereals, and that of animal foods was low, especially eggs and milk and milk products. The daily intake of niacin was sufficient, and the intakes of energy and iron were also tend to be adequate. On the contrary, the intakes of vitamin A, $B_2$ and C, calcium and protein were insufficient. The mean red blood cell number was $410.8{\pm}26.4{\times}10^{4}/mm^{3},$ the mean values of Hb, Hct and MCHC were $12.5{\pm}0.9gm%$, $37.5{\pm}2.4%$ and $33.2{\pm}0.5%$ thus the anemic prevalences were 21.3%, 12.8% and 93.6% comparing with the anemic criteria of WHO. The levels of serum protein and serum albumin were $7.1{\pm}0.4gm\;%$ and $4.3{\pm}0.3gm\;%$so the A/G ratio was indicated $1.6{\pm}0.2.$. The levels of serum iron and TIBC were $91.9{\pm}27.5{\mu}g/100ml and $297.5{\pm}31.4{\mu}g/100ml,$ so TS was calculated $31.2{\pm}9.7\;%$. The mean value of SG was $1.044{\pm}0.002,$ and the level of serum cholesterol was $164.3{\pm}25.4mg/dl$. In the relation between each of bloood content, Hb showed positive correlation not only with Hct but also protein at the level of significance of 1 per cent and 5 per cent, and protein also showed a positive correlation with serum cholesterol at the 1 per cent level of significance. In the relation between the nutrient intake and blood contents, vitamin C intake showed a positive correlation with Hb, serum protein and serum iron at the level of significance of 1 per cent, iron intake also showed a positive correlation with serum iron and serum cholesterol at the same significant level, and protein intake showed a positive correlation with serum iron at the at the level of significance of 5 per cent.

This study was carried out to investigate the effects of vitamin E on the prevention and treatment of Babesia gibsoni. Fifteen mongrel dogs, uninfected with Babesia spp, were assigned to three groups according to vitamin E(${\alpha}-tocopherol$) concentrations in the RBC. The concentrations in each of the three groups were, respectively : ${\alpha}-tocopherol$ in RBC less than $30{\mu}g/{\mu}l$(Group I), $30{\mu}g/{\mu}l{\sim}60{\mu}g/{\mu}l$(Group II), more than $60{\mu}g/{\mu}l$(Group III). Artificial infection was accomplished by injecting $2{\times}10^7{\sim}2{\times}10^8$ erythrocyte of Babesia gibsoni-infected dog into the cephalic vein. We investigated the clinical signs, vitamin E concentrations in RBC and serum, Vitamin A concentrations in serum, hematological values, white blood cell(WBC) viability and RBC membrane osmotic fragility after infection of Babesia gibsoni for a period of 20 days at 5 day intervals. The results obtained are summarized as follows : 1. After infection by Babesia gibsoni, clinical examination revealed depression, anorexia, pale mucous membranes, dark brown urine and diarrhea in proportion as time went on. After 10 days of infection, one dog each of Groups I, II and III revealed depression and anorexia. Two dogs in Group I and one dog each of Groups II and III showed dark brown urine after 15 days. Diarrhea was observed in one dog in each of the 3 groups after 20 days of infection. 2. After 5 days of infection, two dogs in each of Groups I, II and III showed Babesia gibsoni in RBC of blood smear stained with Giemsa. At the 15th day after infection with Babesia gibsoni, they were observed in all experimental animals. After both 5 days and 10 days of infection, the rate of Babesia gibsoni parasitized RBC(permillage, ‰) was 1‰, and increased as time went on. 3. After 5 days of infection by Babesia gibsoni, Group I, which had the lowest vitamin E concentration, showed significantly decreased RBC and PCV levels(p < 0.01). Group II and group III also showed significantly decreased RBC and PCV levels after 15 days of infection(p < 0.05). Particularly after 10 days of infection, Group I showed lower values in RBC and PCV levels compared to Groups II and III. WBC, RBC, fibrinogen and total protein levels between the groups did not differ during experimental periods. 4. According to the WBC differential counts, the ratios of neutrophil to lymphocyte showed a tendency to be slightly higher in Group III (more than $60{\mu}g/{\mu}l$) than in Groups I and II. 5. WBC viability did not differ between the groups. 6. RBC membrane osmotic fragility did not differ between the groups.

The purpose of this study was to compare nutrient intakes and the serum iron status of 74 Food and Nutrition major, and 45 non-major, female students at a university in Incheon. This cross-sectional survey was conducted using a self-administered questionnaire and the data were analyzed by the SPSS 10.0 program. The nutrient intake data collected from three-day dietary recalls were analyzed by the Computer Aided Nutritional Analysis Program. Anthropometric data and hematological indices of iron in the blood were measured. Average heights, weights, body fat and mid-upper arm circumference of Food and Nutrition major and non-major female students were 160.3 cm, 53.5kg, 25.8%, 23.7cm and 159.8cm, 55.5kg, 28.9%, 24.8cm, respectively. There were significant differences in body fat percentage and mid-upper arm circumference between the major and non-major students. In all subjects, daily dietary intakes of nutrients- except protein, vitarrlin B1, vitamin C and phosphorus - were lower than the Korean RDA. In particular, calcium and iron intakes of all subjects were under 60% of the Korean RDA. Values of RBC (red blood cell) count, Hb (hemoglobin), Hct (hematocrit), MCV (mean cell volume), MCH (mean cell hemoglobin), and MCHC (mean corpuscular hemoglobin concentration) of the non-major students were significantly higher compared to those of the major students. The diastolic blood pressure of the major students was negatively correlated with MCV, MCH, TS, and serum iron levels. Triceps skinfold thickness, mid-upper arm circumference and waist-to-hip ratios of the non-major students were negatively correlated with TIBC. Fat intake was positively correlated with RBC, Hb, Hct, and TIBC (total iron binding capacity) in the major students. Vitamin C intake was positively correlated with serum iron in the major students. Carbohydrate intake was positively correlated with Hb, Hct, and MCHC in the non-major students. Niacin and iron intakes were positively correlated with Hb and Hct in the non-major students. Therefore, nutrition education is necessary for female university students to improve nutritional status and to practice optimal nutrition strategies. (Korean J Nutrition 35(9) : 952~961, 2002)

This study was conducted to investigate dietary and other factors affecting bone mineral density (BMD) in Korean premenopausal women. Seventy-eight premenopausal women who visited health promotion center for health examinations volunteered to participate in this study and they were divided into two groups according to the bone status by T-score : normal or osteopenic group and osteoporotic group. The demographic and general characteristics, and dietary intake were surveyed using the questionnaire. BMDs of the lumbar spine and femoral neck of subjects were measured by dual energy X-ray absorptiometry. Serum samples were measured for Lipid concentration, and calcium, phosphorus, alkaline phosphatase as bone formation indicators. Urine was analysed for creatinine as bone resolution indicators. The results are as follows:The mean BMDs of the lumbar spine and femoral neck were 1.21 0.02g/cm$^2$ and 0.97 0.04g/cm$^2$, respectively and the BMD levels of osteoporotic group were significantly lower than that of normal or osteopenic group (p<0.001, respectively). Height in osteoporotic group was significantly lower than that of normal or osteopenic group (p<0.01), and bodyweight did not show any significant difference but had a lower tendency. Mean daily intake of energy was 1720 52ka1. When nutrient intake was compared with recommended dietary allowances (RDA) of subjects, calcium, Fe, vitamin A and riboflavin intakes showed means lower than RDA. The nutrient intake did not show any significant difference between normal or osteopenic group and osteoporotic group except intakes of protein fat and niacin. Serum and urine levels did not show any significant differences between normal or osteopenic group and osteoporotic group and all were within normal range, however, serum alkaline phosphatase level of osteoporotic group was significantly higher than that of normal or osteopenic group (p<0.001). Height showed positive correlations with lumbar spine bone mineral density (LBMD, r=0.332, p<0.01), no correlation was found with femoral neck bone mineral density (NBMD). Age, age at menarche, bodyweight, body mass index (BMI) and obesity showed no correlation with BMD. The BMD of the lumbar spine was significantly and positively related to the intake of niacin and vitamin C (r=0.236, p<0.05; r=0.274, p<0.05). Serum levels of calcium and phosphorus showed a negative correlation with LBMD (r=-0.698, p=0.0001; r=-0.503, p=0.0001, respectively). The results suggested that the BMDs of the lumbar spine was positively related to the intake of niacin and vitamin C in premenopausal women. Therefore, this study confirmed that one of the most effective way to minimize bone loss would be higher intake of niacin and vitamin C rich foods and habitual physical activity may have a beneficial effect on BMD in premenopausal period.

Dietary and other factors affecting bone density of 32 Korean healthy college women aged 19-23 years were assessed. Data for food and nutrient intake was obtained by a semiquantitiative food frequency questionnaire. Serum samples were anlayzed for total Ca, P, Ca++, PTH, calcitonin and 25-hydroxycholecalciferol , (25-OH-Vit D3) and BMDs of lumbar spine(L2-L4), femoral neck(FN), ward's triangle (WT) and trochanter(TR) were measured by an XR-series X-ray bone densitometer. Relationships between the factors and BMDs were analyzed by stepwise multiple regression analysis and Pearson's correlation coefficient(r). The results are summarized as follows. Mean daily intake of energy(86.1%), Ca(74.3%), vitamin A (53.75), Fe(49.75) and vitamin B$_2$(86.6%) were lower while other notrients incuding P(126%) were higher than the Korean RDA. The BMDs of lumbar spines and femurs ranged from 0.73g/$\textrm{cm}^2$ to 1.23g/$\textrm{cm}^2$and 0.48g/$\textrm{cm}^2$ to 1.04g/$\textrm{cm}^2$, respectively. Both protein and P intakes were inversely associated with serum total Ca. Furthermore, Ca intake as well as Ca/P ratio (Ca/P) were inversely associated with serum ionized Ca(Ca++) concentration. The intakes of protein P and Ca , however, were not significantly associated with the BMDs measured in this study. There were little association between BMDs and alcoholic beverage or caffeine consumption. The only significant association detected was a positive relationship between caffeine consumption and BMD of WT. It seemed to be noticeable that BMDs of L2-L$_4$, FN and WT were significantly inversely associated with serum P concentration. However, there was no significant association between BMDs and the levels of total Ca to Ca++ in serum. Body weight was positively associated with BMD of lumbar spine and BMI was also positively associated with BMDs of FN and WT. The subjects who had an early menarche appeared to have higher BMDs than those who had had a late mearche. According to stepwise multiple regression analysis. Menarche and BMI were stronger determinants of BMDs in the young women than was diet. P intake appeared to be a more potent dietary determinant than Ca intake. The three factors, menarche, BMI , and P intake , additionally accounted for 24% and 378% of the variance in BMDs of FN and L$_2$-L$_4$, respectively. Further investigation is necessary to determine the factors needed to increase serum P level which negatively affects. BMD in young Korean college women.

This study was carried out to examine the association of age, nutrient intake, alcohol drinking and smoking on serum lipid and apolipoprotein levels in 100 healthy adults (54 males and 46 females). The serum total cholesterol, low density lipoprotein cholesterol (LDL-C) (p<0.05), apolipoprotein B (Apo B) levels, LDL-C:high density lipoprotein cholesterol (HDL-C) ratio, Apo B:apolipoprotein(Apo A-I) ratio and atherogenic index (AI) (p<0.001) were significantly higher in males than females, but HDL-cholesterol level was significantly lower (p<0.01) in males than females. The plasma ascorbic acid concentration had no difference in both genders. Most of nutrient intakes except Ca, vitamin A and vitamin $B_2$ were higher than RI (Recommended intake) in both males and females. The meal frequency per day was significantly higher (p<0.01) in males than females, while meal speed, the heaviest meal, meal quantity and meal regularity had no significant differences. The rates of drinking and smoking were significantly higher (p<0.01) in males (59.3%, 37.2%) than females (17.3%, 6.9%). The age was positively correlated with triglyceride level in males (p<0.05), and with total cholesterol (p<0.001), LDL-cholesterol (p<0.001), Apo B (p<0.01), LDL-C:HDL-C ratio (p<0.01), Apo B:Apo A-I ratio (p<0.05) and AI (p<0.01) in females. The levels of serum lipid and apolipoprotein were more correlated with protein intake than other macronutrient intakes in males, while those in females were more correlated energy, carbohydrate and lipid intakes than protein intake. The effect of drinking on serum lipid and apolipoprotein levels was bigger in males than females, while the effect of smoking on those was bigger in females than males. The plasma ascorbic acid concentration was positively correlated with HDL-cholesterol (p<0.05), Apo A-I levels (p<0.001), whereas negatively correlated with Apo B:Apo A-I ratio (p<0.05) in males. And that was positively correlated with HDL-cholesterol (p<0.05) in females. These results suggest that moderate macronutrient intake, less alcohol consumption and non-smoking were necessary to maintain healthy lipid profile with aging in adults.
