This study was designed to assess the iron nutritional status and anemia of high school students. 383 female subjects in Ulsan Metropolitan city were evaluated using a questionnaire, and a measurement of hematological indices. The average height and weight of the respondents were 161.24$\pm$4.90 cm and 53.12$\pm$6.37kg, repectively. The average BMI(body mass index) was 20.43$\pm$2.26 which was in the normal ramge. The average hemoglobin(Hb) concentration of the subjects was 13.14$\pm$0.97g/dl, and the average hematocrit(Hct) level was 40.84$\pm$17.40%. Transferrin saturation{TS(%)} was 20.86$\pm$10.32%, and the ferritin by Hct(＜36%), 27.2%by TS(＜14%),26.6% by ferritin(＜12 ng/ml). As for clinical symptoms, the greatest number of respondents reported that they experienced ‘decreased ability to concectrate’. Mean daily intakes of iron were 14.89$\pm$4.48 mg and heme iron intakes were 5.04$\pm$2.13 mg, which was 29.6% of total iron intake. The total iron binding capacity(TIBC) was negatively correlated with Hb concentration(r= -0.222, p＜0.01). Serum ferritin was positively correlated with Hb concentration(r= - 0.323, p＜0.05) and negatively correlated with TIBC(r= -0.367, p＜0.01). TS(%) was positively correlated with Hb concentration(r= 0.402, p＜0.01) and positively correlated with serum ferritin(r=0.413, p＜0.01). As for the correlation between blood biochemistry and clinical symptoms related to anemia, the Hb concentration was negatively correlated with ‘shortening of breath when going upstairs(p＞0.05)’ and ‘cold hands and feet’ significantly(r= -0.109, p＜0.05). The level of Mean corpuscular volume(MCV) was negatively correlated with ‘feel dizzy when standing up’,‘tired out easily’, and ‘decrease ability to concentrate’ significantly(p＜0.05). In particular, the level of Fe was negatively correlated with ‘shortening of breath when going upstairs’ and ‘feeling blue’ significantly(p＜0.01). These results suggest That the prevalence of iron deficiency of female high school students is very high, therefore guidelines for diet supports and nutrition education to improve their iron status should be provided.

Many women in the world have suffered from anemia produced by menstruation, pregnancy and delivery. In the theory of oriental medicine, a sour taste is believed to have a tonic effect on the blood. Thus this paper is to investigate the effect of sour tastes on the improvement in anemia-induced female mice, using citric acid and Fructus schizandrae(五味子). The method used in this experiment was the change of RBC, WBC, Hemoglobin, Hematocrit, Fe, and TIBC in the blood of female mice who were fed citric acid and Fructus schizandrae(五味子). The results obtained were as follows ; 1. Compared with the control group (anemia- induced group without treatment), the mean number of RBC in the blood of mice was significantly increased only in evaluating the change of sample group fed Fructus schizandrae (五味子) 500mg/kg. 2. Compared with the control group (anemia- induced group without treatment), the mean number of WBC in the blood of mice was not significantly larger in both sample groups fed citric acid and Fructus schizandrae(五味子). 3. Compared with the control group (anemia- induced group without treatment), the mean number of Hemoglobin in the blood of mice was significantly larger only in evaluating the change of the sample group fed Fructus schizandrae(五味子). 4. Compared with the control group (anemia- induced group without treatment), the mean percentage of Hematocrit in blood of mice was significantly increased only in evaluating the change of sample group fed Fructus schizandrae(五味子) 500mg/kg and sample group fed Fructus schizandrae(五味子) 250mg/kg for 3days. 5. Compared with control group (anemia- induced group without treatment), the mean volume of Fe in serum of mice was significantly increased only in evaluating the change of sample group fed Fructus schizandrae(五味子) 500mg/kg. 6. Compared with control group (anemia- induced group without treatment), the mean TIBC in serum of mice was significantly increased only in evaluating the change of sample group fed Fructus schizandrae(五味子) 500mg/kg and sample group fed Fructus schizandrae(五味子) 250mg/kg for 7days. According to these results, a sour taste is presumed to have a general tonic effect on anemia, but more study must be taken on the effects of citric acid in improving female anemia.

This study is to investigate the status of anemia, especially iron deficiency anemia among pre-school children in rural area in Korea. The survey was conducted in Sang-dae Ri, Yusong Myon, Daedok Gun, Chung Chong Nam-Do from July 30 th to August 12th, 1968. The measurements were done of height, weight, hematologist and biochemical levels on ninety-two pre-school children, 47 male, and 45 female, one to six years of age. Hemoglobin was determined by the method of cyanmethemoglobin and hematocrit by micro hematocrit centrifuge. The determination of serum iron, iron-binding capacity was done by the method of Ramsay using bathophenanthroline and the serum albumin was determined by Biuret Reaction. The results of this study are as follows: 1) 54.4 percent of the pre-school children weighed less than 90 percent of the Korean General Standard Weight level. 2) The average hemoglobin level was $11.0{\pm}1.57gm/100ml$, 38.0 percent of the children were anemic with less than 1.0gm/100ml. Of the anemic children 60 percent were below the Korean General Standard Weight level. 3) 27.5 percent of the pre-school children were found to have below 32 percent of a hematocrit values and 28.0 percent showed less than 33 percent in M.C.H.C. These results showed that the incidence of hypochromic anemia in these pre-school children was high. 4) 37.9 percent of these children had a serum iron level less than $50{\mu}g/100ml\;and\;31.0\;percent\;had\;a\;TIBC\;above\;400{\mu}g$ while 48.3 percent showed a transferrin saturation lower than 15 percent. On the basis of these findings, it is concluded than the cause of this anemia was iron deficiency. 5) In this group there was a little evidence of low total serum protein levels. However, 10.4 percent of the children had a deficient serum albumin level, below 2.80 gm/100ml while 51.7 percent had a low level, less than 3.50gm/100ml, and 34.5 percent of the children had a low level of TIBC, less than $350{\mu}g/100ml$, and considering these facts, it is suggested that some of the anemias have a multiple causes through protein deficiency and repeated chronic infection apart from iron deficiency.

This study was designed to investigate the effect of iron supplementation on the iron nutritional status and anemia of high school girls in Korea. One hundred thirty-five female students residing in Ulian metropolitan city in Korea diagnosed as having anemia or iron deficiency participated in this study. One or two tablets of iron medicine(80-160 mg Fe as ferrous sulfate/day) were administered to all participants for 3 months. Subjects were evaluated with a questionaire, measurement of hematological indices before and after iron supplementation. The average height and weight of respondents were 161.62 $\pm$ 4.68 cm and 53.87 $\pm$ 6.10 kg, respectively. Daily intakes of energy were 1597.8 $\pm$ 302.35 kcal(76.0% RDA). Iron intakes were 13.72 $\pm$ 4.17 mg (76.3% of RDA) and calcium intakes were 580.74 $\pm$ 177.21(72.5% of RDA) before iron supp]ementation. At baseline, 63% of all participants had depleted store(serum ferritin 12 ug/ml and/or transferrin saturation(TS) < 14%). After iron supplementation, this proportion declined to 19.3%. 55.6% of subjects had 12 ug/m1 of basal ferritin concentration before iron supplementation, and this proportion declined to 16.3% after iron supplementation. The basal hemoglobin(Hb) concentrations were 12.13 $\pm$ 1.01 g/dl and they increased to 12.79 $\pm$ 0.81 g/dl, which showed significant difference artier iron supplementation(p < 0.001). The basal ferritin and TS(%) were 13.24 $\pm$ 11.66 ng/ml, 18.42 $\pm$ 10.12% and they significantly increased to 32.95 $\pm$ 21.14 ng/ml, 33.53 $\pm$ 16.64%, respectively(p < 0.001). The basal total iron binding protein(TIBC) were 467.81 $\pm$ 97.24 ug/dl and they significantly decreased to 325.05 $\pm$ 48.89 ug/dl(p < 0.001) after iron supplementation. The number of tablets administered was positively correlated with serum iron(t = 0.553, p < 0.01), serum ferritin(t = 0.557, p < 0.01), TS(%)(t = 0.588, p < 0.01) and negatively correlated with TIBC(t= -0.409, p <0.01). The anemia symptoms such as ‘Shortening of breath when going upstairs(p < 0.01)’, ‘Tired out easily(p < 0.01)’, ‘Feeling blue(p < 0.001)’, ‘Decreased ability to concentrate(p < 0.01)’, and ‘Poor memory(p < 0.001)’improved significantly after iron supplementation. In this study, daily iron supplementations were efficacious in improving the iron status and anemic symptoms of female high school students. Regular check-ups and nutrition education for adolescents are necessary because of their vulnerability to iron deficiency. Further studies are needed to determine the minimum effective dose of iron and to examine the adverse effect of long-term iron supplementation.

고강도운동 시간이 레트의 혈액학적 조성과 염증관련 인자의 변화에 미치는 영향을 연구하였다. 고강도운동을 매일 20, 60, 그리고 120분 동안 8주간 실시하였다. 거의 모든 혈액세포수의 측정에 있어서 고강도운동이 미치는 영향은 거의 찾아볼 수 없었으나 백혈구의 경우 대조군보다 47% 더 증가한 것으로 나타났고 60분 이후로는 대조군의 70% 수준까지 감소하였다. 60분 혹은 그 이상의 시간 동안 운동을 했을 경우 혈청 내 $Fe^{++}$, UIBC, 그리고 TIBC수준이 대조군에 비해 유의성 있게 증가한 반면 20분간의 운동에서는 이들의 변화를 볼 수 없었다. 염증촉진성 사이토카인인 IL-6와 항염증성 사이토카인인 IL-10 모두의 혈청 내 수준이 고강도운동에 의해 증가하였으나 운동시간 대비 IL-6의 증가폭이 훨씬 높은 것으로 보아 염증반응의 내재 가능성을 보여주었다. 혈청 내의 인터페론-감마는 20분과 60분의 고강도운동에서 증가하였으나 120분에서는 그 수준이 대조군보다 낮아졌다. 혈청내의 nitric oxide 농도는 고강도운동에 의해 높아졌다. 전반적으로, 본 연구에서 보여진 장시간의 고강도운동에 의한 유사염증 반응은 혈류의 상승과 산소요구량이 높아진 결과로 사료되며 본 연구의 조건하에서는 고강도의 운동은 단시간운동이 건강관리에는 도움이 되는 것으로 사료된다.

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.

Magnesium (Mg) plays an essential role in physiological and metabolic reactions. Recently, there has been an increased interest in the role of Mg deficiency, particularly the relationship between serum Mg value and inflammatory response. This study was designed to determine the relationship between serum Mg deficiency with inflammatory response, electrolytes and hematological alteration over long-term periods. Sixteen male Sprague-Dawley rats were divided into two groups: control (n=8), and Mg deficiency group (MgD group, n=8). Chow and normal water (tap water) were regularly provided to the control group and Mg-depleted chow and third distilled water were regularly provided for 60 days to the MgD group. Body weights, Serum Mg, $K^+$, inorganic phosphorus (IP) and total iron binding capacity (TIBC) levels in the MgD group were lower than those of the control group (P<0.05). Granulocyte fraction and MCV, RDW and PDW levels were higher, whereas lymphocyte fraction, erythrocyte, hemoglobin and MCHC levels were lower in the MgD group than in the control group (P<0.05). MCP-1 and TNF-${\alpha}$ levels in the MgD group were greater than those of the control group (P<0.05). In conclusion, the results of the present study suggest that Mg deficiency over a long-term period had not altered total leukocyte concentration in the blood, but had detrimental effects, including disturbances of electrolytes balance, disturbance of iron indices, potential anemia and elevation of pro-inflammatory cytokine. However, further studies should be performed to determine the relationship between serum Mg deficiency and major organ damage or alteration.

The purpose of this research is to measure nutrition counseling effects for improving iron status. The major components of the nutrition counseling were iron, MPF(Meat, Poultry, Fish) and vitamin C rich diet therapy, the provision of nutrient supplements and eatting attitude education. Fifteen female volun teers participated and the mean level for hemoglobin(Hgb), hematocrit(Hct), serum iron(S Fe), total iron binding capacity(TIBC), serum ferritin(SF) of subjects was 11.9±1.3g/dl, 37.0±2.7%, 57.7 ±33.9 g/dl, 409.1±56.2 g/dl, 8.6±3.5ng/ml, respectively. To evaluate the effect of iron status improvement by the nutrition couseling, 10 subjective symptoms, hematological indice and eating attitude were measured after implementation the nutrition counseling. Some subjective symptoms such as 'cold hands and foot', 'slow to recover', 'reduced concentrate', 'poor memory', 'inflammed inner mouth' were improved significantly. The hemoglobin, hematocrit, mean cell volume(MCV), mean cell hemoglobin(MCH) and mean cell hemo globin concentration(MCHC) were increased significantly. And eating attitude was improved significantly as well. It is suggested from the results that the nutrition counseling of this study can be effective to improve iron status.

This study investigated the effects of dietary phyate reduction on the apparent absorption and biochemical parameters of iron status in young Korean women. Fourteen healthy, young women consumed low and high phytate diets for ten days of each experimental period. Duplicate diet samples, a fasting blood sample on day 9, and complete fecal samples for five consecutive days starting from day 5 of each diet period were collected. The iron content of diet and fecal samples were analyzed to calculate apparent absorption. Serum samples were analyzed for iron, ferritin, transferrin receptor and TIBC; transferrin saturation was also calculated. The apparent absorption of iron tended to increase in the low phytate period (32.51%) compared to the high phytate period (17.91%), but the difference was not significant (p=0.06). Serum ferritin decreased and serum transferrin receptor increased significantly during the low phytate diet although the mean values were within the normal range. Serum iron and transferrin saturation did not change significantly. In conclusion, the results indicated that reducing dietary phytate for ten days negatively affected iron nutritional parameters, but it moderately and positively affected apparent iron absorption in young Korean women. Further research on the long-term effects of a low phytate diet with an adequate iron content for vows Korean women is necessary.
