  • Anemia is a usual finding in advanced malignant diseases. Various mechanisms were reported as to be involved in the development of anemia of this kind, and they may differ in individual cases. Tumor anemias may be due, for instance, to chronic blood loss, shortened life span of the red blood cells or a decreased hemopoiesis in the bone marrow. The serum iron and copper levels, total iron binding capacity, apparent half survival of $^{51}Cr$-labelled red blood cells were measured along with the ferrokinetic studies using $^{59}Fe$ in 64 patients with various malignant tumors. Following were the results: 1. The serum iron levels were decreased in all cases. There existed no correlation between the serum iron levels and the severity of the diseases. 2. The serum copper levels were increased, particularly in lung cancer, rectal cancer, hepatoma and various sarcomas. There was also no correlation between the serum copper levels and the severity of the diseases. 3. The serum iron levels appeared to be inversely proportional to the serum copper levels. 4. The total iron binding capacities were within normal limits in all cases. There were also no correlations between the total iron binding capacities, serum iron levels and the severity of the diseases. 5. The patients could be classified according to the ferrokinetic patterns, namely, that of iron deficiency anemia in 10 cases, that of refractory anemia in 6 cases, normal in 1 case and that of atypical abnormal in 9 cases. 6. Apparent half survival time of $^{51}Cr$-labelled red blood cells were definitely shortened in half of the cases.

  • Purpose: The purpose of this study was to investigate the relationship between Helicobacter pylori (H. pylori) infection and iron-deficiency anemia in pubescent children, susceptible to iron deficiency due to the high iron requirements for growth. Methods: Hemoglobin, serum iron, total iron-binding capacity, serum ferritin, and serum IgG antibodies to H. pylori were measured in 937 children (475 boys and 462 girls). Their ages ranged from 10 to 18 years. The prevalences of H. pylori infection were compared between groups, based on the presence or absence of anemia, hypoferritinemia, iron deficiency, and iron-deficiency anemia. The levels of hemoglobin, serum iron, total iron-binding capacity, transferrin saturation, and serum ferritin were obtained according to the presence or absence of H. pylori infection. Results: The prevalences of anemia, iron deficiency, iron-deficiency anemia, and H. pylori infection were 8.1%, 9.1%, 3.1%, and 20.8%, respectively. The H. pylori-positive rates in anemia, hypoferritinemia, and iron-deficiency group were 34.2%, 29.5%, and 35.3%, respectively, compared to 19.6% in the non-anemia group, 19.2% in the non-hypoferritinemia group, and 19.4% in the non-iron deficiency group. The H. pylori-positive rate in the iron-deficiency anemia group was 44.8% in comparison with 20.0% in the non-iron-deficiency anemia group. Hemoglobin and iron levels did not show any significant differences between the H. pylori-positive and -negative groups, whereas the serum ferritin level decreased significantly in the H. pylori-infected group. Conclusion: H. pylori infection is thought to be associated with iron deficiency in pubescent children.

  • To evaluate iron nutritional status and to compare biochemical indices used for evaluation of iron nutriture, fasting blood sample was taken from 96 Korean female college student and hemoglobin(Hb) concentration, hematocrit(Hct), serum iron, total iron binding capacity(TIBC) and serum ferritin concentration were measured and transferrin(TF) saturation was calculated. Prevalence of iron deficiency varied from 4.2% when judged from Hb concentration and Hct to 38.5% and 40.6% when TIBC and serum ferritin concentration were used. TIBC was negatively correlated with serum ferritin(r=0.4561, p<0.001), while other indices showed positive but less significant correlations(p<0.05). Regarding iron status judged by serum ferritin was regarded as true iron status, the present cutoff points of Hb, Hct, serum iron, TF saturation were very insensitive in identifying the subjects with iron deficiency. Only TIBC was suitable for detecting iron deficiency in the study subjects. It is concluded from the study results that iron deficiency in young Korean adult women would be significantly underestimated with presently used biochemical measurements except TIBC and new cutoff points of these indices were proposed based on sensitivity, specificity measured prevalence, and positive and negative predictive values.

  • The purpose of this study was to examine nutritional status of iron in 27 rural elderly subjects. The daily intake, urinary excretion and serum level of iron were determined by 24-hr food collection method, and 24-hr urine and serum collection for 3 days. The results were summarized as follows. 1. The mean age, height, weight, and blood pressure were 67.7 years, 163.2cm, 55.9kg, and 121.1/80. 0mmHg in men and 69.9 years, 146.5cm, 47.6kg, and 108.9/71.1mmHg in women, respectively 2. The daily intake of energy, protein, vitamin A, vitamin B$_1$, vitamin B$_2$, niacin, vitamin C, and iron were lower than Korean recommended dietary allowances. 3. The daily iron intake was 7.82mg. The proportion of heme iron and nonheme iron to the total iron intake were 8.05% and 91.94%, respectively Major iron sources of the rural elderly were cooked rice, Ko Chu Jang, beef blood, anchovy, soybean paste, and leafy radish. 4. The hemoglobin, hematocrit, serum iron, and total iron binding capacity were 14.3g/㎗, 42.9%, 79.4 $\mu\textrm{g}$/㎗, and 268.4 $\mu\textrm{g}$/㎗ in men and 12.9g/㎗, 38.8%,92.4 $\mu\textrm{g}$/㎗, and 277.9$\mu\textrm{g}$/㎗ in women, respectively. 5.

  • Essential metals have been known to interact with non-essential toxic metals in the aspects of absorption, transport and deposition in the body. Iron deficiency has been reported to increase lead and/or cadmium absorption. The relation between iron and lead has been understood well in children but not in adults. Two hundred seventy adults (118 males and 152 females) were recruited from 3 different residental areas (rural, coastal and urban) to investigate the effects of environmental lead exposure on body iron status. The subjects were interviewed for life-style and diet of the last 24 hours, and measured for blood lead and body iron. The lead concentration in the whole blood was determined by a flameless method using an atomic absorption spectrophotometry. The body iron was evaluated with values of hemoglobin, hematocrit, RBCs, serum total iron, unsaturated iron binding capacity, total iron binding capacity and ferritin. The mean concentration of blood lead in adult was $3.31{\mu}g/dL$. The concentration was higher in male ($3.97{\mu}g/dL$) than in female ($2.86{\mu}g/dL$). The blood lead was influenced by residental area, life-style, smoking and drinking, occupation and diet habit of subjects, but not by age. A positive correlation was observed between the blood lead level and the serum iron or ferritin. These results suggest that environmental lead exposure in Korean adult may not be higher than other developed and developing countries. It is further indicated that blood lead in adult could be influenced by life-style, and environmental and genetic factors but no inverse relation with body iron as shown in children.

  • Nutritional Status of 74 elderly Koreans(35 men and 39 women) from middle-income households in Incheon were evaluated in terms of dietary nutrient intakes, anthropometric measurements and biochemical blood analysis. The mean consumptions of all nutrients were lower than R.D.A except iron, thiamine and niacin. However, 25.7% of men and 33.3% of women consumed less amount of iron than 75% of R.D.A. Average body mass index of women was sightly but significantly higher than that of men (P<0.05). Obesity rate and triceps skinfold thickness of women were much higher than those of men (23.3% vs 5.4% and 14.9mm vs 9.6mm, respectively). By judging from amounts of hemoglobin, hematocrit, serum iron, total iron binding capacity, mean corpuscular hemoglobin concentration and transferrin saturation of the elderly, 5.6-33.3% of men and 5.0-33.3% of women seem to be possibly anemic.

  • This study was performed to investigate the iron status and its related factors in female college students residing in Gyeongnam. The prevalence of iron deficiency among subjects ranged from 3.4% in mean corpuscular hemoglobin concentration (MCHC) to 43.7% in ferritin. Weight, lean body mass (LBM) and body mass index (BMI) were positively correlated with ferritin concentration, but negatively correlated with total iron binding capacity (TIBC). Among the nutrients, vitamin A and B2 were major predictors of elevated iron status. Meal regularity was positively correlated with Fe and ferritin concentration, and meal number with transferrin saturation (TS), meal quantity with red blood cell (RBC) and hematocrit (Hct). Consumption of fruit, meat, fish and poultry showed strong positive correlation with hematological indices. Therefore, increasing vitamin A, B2, C, and iron intakes as well as maintenance of a healthy weight may be helpful in preventing iron deficiency in female college students.

  • This research analyzed the iron status, clinical symptoms and physical characteristics between normal and anemic group of middle school girls in the Ulsan metropolitan area. It was carried out with 237 subjects (normal 190, anemic subject 47). They were evaluated with a questionnaire and measurement of hematological indices. BMI $(kg/m^2)$ of the two groups were $19.54{\pm}2.44$ (normal girls) and $19.22{\pm}2.27$ (anemic girls). The hemoglobin concentration of the anemic girls were $10.84{\pm}1.17g/dl$ and the serum iron of the anemic girls represent $35.15{\pm}27.47{\mu}g/100ml$. The TIBC (Total Iron Binding Capacity) of the anemic girls showed significantly high to $449.30{\pm}64.87{\mu}g/100ml$. The serum ferritin of the anemic girls was $20.53{\pm}42.29{\mu}g\ell$, it represented significantly low. The symptom of 'pale face' of the anemic girls were higher than the normal girls. Hemoglobin and serum iron were negatively correlated with 'pale face'. The TIBC was negatively correlated with 'Get a cold easily'. The duration and amount of menstruation were correlated with iron status. This research is to be utilized as basic data for dietary support and nutritional education to improve their iron status.

  • 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.
