  • 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.

  • Nutritional anemias are an important nutritional problem affecting large population groups in most developing countries. Many reports on investigations of nutritional anemias have been published and there is good evidence that prevalence of iron deficiency anemias in vulnerable groups is high in many areas of the world. However, there is a general lack of accurate data on its prevalence throughout the world. Methods used to measure different factors have been variable and often of poor quality. Furthermore recent comparison of values obtained in different laboratories have shown a much greater discrepancy in iron binding capacity measurements as compared with serum iron determinations. Since the major cause of these differences appears related to the technique employed, the efforts of the central laboratory will be directed initially to standardization of methodology. My laboratory has been joined interlaboratory comparison of WHO studies of iron standardization. The determination of serum iron, iron-binding capacity and transferrin saturation was done on healthy adults, 79 males and 20 females, who visited hospital for health certificate from January to July 1970. The serum iron was determined by the method of modification of Bothwell and Mallett and total iron blinding capacity by Ramsay method and Bothwell and Mallett method. The results of this study are as follows; 1) The serum iron concentration of seventy nine adult male by the method presented is $131.5{\pm}37.3{\mu}g/100ml\;(range\;52.5{\sim}225.0{\mu}g/100ml)$ and of twenty female adult is $108.5{\pm}40.2{\mu}g/100ml\;(range\;45.0{\sim}202.5{\mu}g/100ml)$. 2) The adult male level of serum iron-binding capacity is $330.9{\pm}48.9{\mu}g/100ml\;and\;adult\;female\;is\;291.2{\pm}55.2{\mu}g/100ml$. 3) The transferring saturation of healthy male is $35.6{\pm}12.8%\;(range\;15.1{\sim}18.0%)\;and\;of\;female\;as\;25.4{\pm}12.4%\;(range\;10.1{\sim}60.0)$.

  • Iron intake and nutritional status of 99 female college students of Chungnam Natiional Unive-rsity were estimateed with dietary survey and measurement of hematological indices including the level of serum ferritin Food intake was measured using the weighing method and iron availability per meal was calculated according to Monsen and Hallberg. The average daily intakes of protein vitamin C. total iron and also total available amount of iron were higher than the Korean R.D.A. The blood indices for iron status however showed that iron status of the subjects was inade-quate. Furthermore the serum ferritin levels indicated marginal iron storage in 75% of the subjects.

  • The purpose of this research is to compare the effdct of the new weekly iron supplementation on maternal iron and zinc nutritional status with the effect of the present daily iron supplementation. To assess the iron ad zinc status of rpegant women visiting public health center in Ulsan, interview for dietary survey and general aspect of each subject was given and biochemical analysis of blood and urine was performed. The study subjects were divided to two groups randomly, but the subjects whose Hgb level was very low were allocated in daily group ethically because theeffect of weekly supplementation was not yet established as safety. Daily group received 80mg elemental Fe(250mg Fe as ferrous sulfate) per day for 100days, while weekly group received 160mg elemental Fe once a week for 15 weeks. After treatement, Hgb(p<0.01), Hct(p<0.01) , serum iron(p<0.05) and serum ferritin(p<0.001) in weekly group but RBC, Hgb , Hct , serum iron and serum iron and serum ferritin increased slightly. After correction for the initial Hgb by including it in the MANIVA, the difference in treatment effects of Hgb and TIBC between groups was statistically significant. The effect of weekly vs, daily iron supplementation program on zinc status was also studied. The difference in treatment effect between two groups was, however, not sifnificant. It is concluded that once weekly rion supplementation program in pregnant women was less effectgive to improve the iron status than daily iron supplementation program. However, because the weekly dose prevented a decline in Hgb as well as in ferritin, itw effect was positive , given the fact that non-supplemented women almost always exhibit a sifnificant drop in Hgb values. It seems that it will improve the iron status well if the amount or frequency of supplements is to be adjusted . Biweekly supplementation of a different dose or antother type of iron supplement, such as through a gastric delivery system, might be better.

  • 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.

  • The aim of this was to investigate whether the regular consumption of kimchi influences the iron status (RBC , Hb, Ht, MCH, MCV, MCHC, transferrin , serum iron, and ferritin) in volunteers. Healthy male adults(n=12) took part in the study subdivided into the control Ⅰ-phase(for 2weeks), kimchi-phase (for 4 weeks), and control Ⅱ-phase(for 2 weeks). In addition to their normal diet, participant consumed 300g of lactic acid fermented Chinese cabbage kimchi daily for four weeks. In the control Ⅰ and control Ⅱ phases, the participants kept up their normal diets without consuming any fermented foods. Dietary intakes were recorded for 3 consecutive days in each phase, with the aid of household measures. Every two weeks. blood specimens were analysed. Significant differences(p<0.05) between the phases were found in MCHC, and transferrin in blood were not significantly changed during kimchi consumption. However, serum iron and ferritin levels were significantly increased(p<0.05) during kimchi consumption, achieving the highest levels in the fourth week of the kimchi components(ascrobic acid, sulfer compound, organic acid, capsaicin, gingerol , allicin). Because of lacticacid fermented kimchi's potential to prevent anemia , the consumption of this food can be recommended.

  • The purpose of this study is to assess the maternal iron status during pregnancy and to evaluate the relationships bet-ween the iron indices of maternal, umbilical cord serum, placenta and pregnancy outcomes. Venous bloods samples were drawn from 54 pregnant women just before delivery and cord bloods of their newborn babies were collected immediately after birth. And also, placental tissues were extracted. We investigated the difference of the iron status indices of maternal, umbilical cord serum and placental tissue between two gestational age group (PT group, NT group : preform delivery and normal term delivery at 34.9wk and 39.0wk of mean gestational length, respectively) and also assessed correlations of iron status indices of maternal, umbilical cord serum and placenta tissue. And lastly, we related between birth weight and iron status indices of maternal, umbilical cord serum and placental tissue. The concentrations of maternal serum ferritin and of placental iron were significantly higher in NT group (32.1 $\pm$ 21.1 ng/ml, 68.5 $\pm$ 16.7 $\mu$g/g), than those of NT group (20.8 $\pm$ 11.6 ng/ml, 53.2 $\pm$ 17.4 $\mu$/g) respectively (p<0.001). However the serum ferritin of umbilical cord were significantly higher in NT group (PT : 109.4 $\pm$ 65.7 ng/ml, NT : 147.0 $\pm$ 56.8 ng/ml) than those of PT group (p<0.05). Our results showed that a negative association between birth weight (r=-0.361) and maternal serum ferritin and that a positive association between birth weight and umbilical cord serum ferritin (r=0.261). Despite not a significant difference, there was tendency that highest concentration of maternal serum ferritin was associated with the lowest birth weight. These findings indicate that birth weight of newborn is dependent of multiple factors such as maternal iron status during pre-pregnancy, body size, general nutritional status. Although for women who enter pregnancy with low iron stores, enough intakes of iron during pregnancy could produce undesirable pregnancy outcome. Therefore we suggest for successful pregnancy outcome and delivery differential iron supplementation program will be carried out individual pregnant women on the basis of pre-pregnancy nutritional status.

  • This study was designed to estimate mean daily iron intake and its bioavailabi- lity and to assess nutrition knowledge for 144 pregnant women in the last trimester. Serum ferritin concentration was analyzed to estimate their iron stores. Dietary intakes of iron(heme iron and nonheme iron), the amounts of MPF(meat, poultry and fish) and ascorbic acid were assessed by modified 24-hr recall method. The food frequency questionnaire was used to assess subjects usual food consumption patterns. The mean value of serum ferritin was $21.3\pm{15.2ng/ml}$ and 26.4% of the pregnant women had a serum ferritin level <12ng/ml(i.e. depleted iron stores). The mean daily intake of total orin in the pregnant women was 56.5%(17.0mg) of RDA and heme iron intake was 0.94mg which was 5.5% of total iron intake. Total absorbable iron calculated by the method of Monsen was 2.41mg and bioavailability of dietary iron was 2.41%. Food frequency test score of meats group was positively correlated(r=0.443) with the bioaavailability of dietary iron. The mean score on the nutrition knowledge test of subjects was 12.76(out of a possible 20 points). These results indicate that the nutritional iron status may be improved by increasing either the amount of iron in the diet or its availability.

  • The purpose of this study is to evaluate the iron nutritional status by investigating dietary intake and analyzing the hematological iron status indices including serum transferrin receptor (sTfR) in 8 to 28 month old infants md young children taking supplementary foods. The nutrient intake of 60 healthy infants and young children from 8 to 24 months of age was investigated by means of a 24-hour recall method, and the subjects were divided into 2 groups (8- 12 months and 13-28 months) according to age. Venous blood samples from these groups were collected and measured for the following : hemoglobin(Hb), hematocrit(Hct) , mean corpuscular volume (MCV), mean corpuscular hemoglobin, mean corpuscular hemoglobin concentration (MCHC), serum ferritin, serum iron, total iron binding capacity (TIBC), and sTfR. Anemia is defined as hemoglobin < 11g /dl , serum ferritin level < 10ng1m1 for iron deficiency , serum transferring receptor(sTfR) > 4.5mg / 1 for iron deficient erythropoiesis. Total daily calorie intake was 934.6 ${\pm}$ 284.5kcal (98.32% of RDA) on average. Average daily iron intake in infants aged 8 to 12 months was 8.92 ${\pm}$ 3.32mg. The mean daily iron intake in infants aged 13 to 28 months was 7.15 ${\pm}$ 3.35mg (90% of Recommended Dietary Allowance, RDA). Mean values for Hb, Hct sew ferritin and sTfR were 12.10 ${\pm}$ 0.77g141,36.02 ${\pm}$ 2.31%,20.91 ${\pm}$ 11.58ng/m1 and 3.78 ${\pm}$ 1.47mg /1, respectively. In the young children from 13 to 28 months of age, the prevalence of anemia was 5.6%. The prevalence of iron deficiency was 9.5% in those from 8 to 12 months of age, and 27.8% in those from 13 to 28 months of age. The prevalence of iron deficient erythropoiesis was 16.7% in infants aged 8 to 12 months and 44.4% in those aged 13 to 28 months. The prevalence of both serum ferritin level < 10ng/m1 sTfR > 4.5mg/1 was 22% in the young children aged 13 to 28 months. The measureand ment of sTfR may be a promising new tool in diagnosis of iron deficiency in early childhood when the iron deficiency is prevalent. It seems appropriate to emphasize nutritional education and evaluation to promote the iron nutritional status of infants and young children.
