  • Evaluation of soy milk as an iron-rich milk substitute was conducted by feeding commercial soy milk , cow milk and mixed formula(soy and cow milk) to Wistar rats for 8 weeks. Body weight gains were significantly lower in the soy milk and mixed formula groups. Hematocrit, serum iron concentration and TIBC (total iron binding capacity) were measured to determine the iron status of the rats. In these respects, the iron status of the soy milk group was normal. Both serum iron concentration and TIBC as well as hematocrit were abnormal in the cow milk group , which is indictive of severe iron deficiency . Although hematocrit was normal in the mixed formula group, serum iron concentration was lightly low. The work capacities of each group were correlated with serum iron concentration and tIBC rather than hematocrit. The running distance of the soy milk group was about 10 -fold longer than that of the cow milk group. Soy milk may be considered an iron- rich substitute for cow milk due to its higher iron content and bioavailability.

  • 인삼 (Panax ginseng C.A. Meyer)의 뿌리로부터 유도한 모상근의 proton 방출은 철이온의 결핍 또는 nitrate나 ammonium이온에 의해 증가되었다. 철이온 결핍에 의한 수소이온 방출의 증가는 정단 조직에서 나타나는 반면에 nitrate와 ammonium 이온에 의한 수소이온 방출은 기저부위에서 높게 나타났다. 배지의 pH변화에 따른 무기이온의 흡수는 무기이온의 종류에 따라 다양한 양상을 나타냈다. $Ca^{2+}$, $Mg^{2+}$ 그리고 Fe$^{2+}$ 는 pH 4.8 에서 가장 높은 흡수를 나타냈으며, Mn$^{2+}$, $Zn^{2+}$ 그리고 Cu$^{2+}$ 는 pH 3.8에서 가장 높았다. HPLC를 이용한 유리당 및 ginsenoside분석에서, 인삼모상근 유리당 구성의 주성분은 sucrose, glucose 그리고 fructose 였으며, glucose와 fructose는 pH 6.8에서 sucrose는 pH 4.8 에서 함량이 가장 높았다. 반면에 ginsenosides와 phenolic compound의 함량은 MS 배지의 표준인 pH 5.8 에서 가장 높았다. pH 변화에 대한 인삼모상근의 이러한 생리적 반응은 인삼근의 적변유발과 관련된 무기이온의 mobilization 및 흡수기작의 구명을 위한 모델 시스템으로 이용할 수 있는 가능성을 제시하였다.

  • 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.

  • Trace element are involved in enzymatic activities, immunological reactions. physiological mechanisms. Deficiency in some trace elements, such as iron and iodine. is still an important health problem, The role of trace elements deficiency is suspected in various clinical situations and is now confirmed by well designed supplementation studies. However, the importance of trace elements as chinese herbal constituents is not sufficiently appreciated by the oriental medical profession, although in recent years a significant increase of new finding on their essential character in chinese herbal medicine occurred. It is well known that herbal medicine contains a variety of trace elements which would show therapeutic effects with active components in herbal medicine . In china, recent work showed some positive correlation between trace element and traditional chinese medicine (TCM) in terms of therapeutic effects even if their role in therapeutic effects is still obscure. In korea, not much attention has been on the therapeutic importance of trace element contained in herbal medicine Here, the therapeutic effects of trace element in TCM were reviewed and summarized. 1. Iron, copper, zinc and manganese are mainly contained in TCM. In addtion, chromium, magnesium, molybdenum, nickel, alminium, cobalt, arsenic and selenium has been studied for their therapeutic effects 2. Zinc, is decreased in patients who have deficiency of kindney(腎虛) and chronic disease. Fe is decreased in patients who have deficiency of blood(血虛). However copper is increased in patients who have chronic disease and hepatic disease.3 Iron concentration is high in herbs used for tonifying and nourishing yin or blood(補陰補血藥) Zinc concentration is high also in herb used for tonifying kidiney and vital essence(補腎補精藥). In addition. copper concentration Is high in herb used for replenishing qi(補氣藥) 4 In herbal drugs, the therapeutic substances in TCM are not only organic but also inorganic. It seems that trace elements would be one of components in herb for its therapeutic effects. This indicates that therapeutic effects of TCM should be extended not only to herb itself, bur also to trace elements contained in herb.

  • The soluble transferrin receptor(TfR) in human serum has been shown recently to be a truncated form of intact membrane bound receptor containing most of the extracellular domain. We purfied the transferin-free TfR from human serum by immounoaffinity chromatography which produced the single protein identity in high resolution gel chormatography. The monoclonal antibodies(MAb) against purifed serum TfR were produced by fusion of spleen cells o fimmunized Balb/c mice and SP2 cells. Ten hybrids producing MAb specific for serum TfR were identifed and determine their iostypes. A immunoraddiometric assay (IRMA) for serum TfR was established using two monoclonal IgG1 antibodies as the coating and indicator antibodies on the bosis of their suitability in sandwich IRMA of serum TfR. The mean serum TfR levels in the 15 normal male, 15 normal female, and 19 iron-deficient subjects were 5.4$\pm$0.98, 4.6$\pm$0/76, and 18.0$\pm$12.8mg/1, respectively, and the difference in mean values between normal and iron deficient subjects was significant(p=0.0005). There existed the inverse logarithmic relationship(r=-0.9336, p<0.0001) between the serum TfR and ferritin levels.

  • 목 적 : 철 결핍 빈혈과 열성경련은 6개월-2세 사이에 호발하며 철 결핍 빈혈은 영아에서 다양한 신경학적 장애를 일으키고 열성경련은 간질과 관련이 될 수 있다. 그러나 이들의 연관관계에 대해서는 상반된 보고가 있어 그 관련성을 규명하고자 본 연구를 시행하였다. 방 법 : 2007년 1월 1일부터 2009년 7월 31까지 원광대학교병원 소아청소년과에 입원치료 받은 9개월에서 2세사이의 발달 지연이나 신경학적 결함 및 중추신경계 감염이 없는 열성 경련 환아 100명과 열성 경련이나 이전의 경련 병력이 없이 발열 증세를 보인 100명을 대조군으로 선정하여 의무 기록지를 이용하여 후향적으로 조사하였다. 결 과 : 열성경련 군과 대조군, 단순 열성경련 군과 복합 열성 경련 군 사이의 평균 연령, 성별, 원인질환별 차이는 없었다. 복합 열성경련 군에서 단순 열성경련 군에 비해 총 경련 횟수, 내원시 경련 시간과 횟수가 의의 있게 높았으며, 경련 시 최고 체온과 전체 열 발생 기간은 높았으나 통계적 차이는 없었다. 철 결핍 빈혈은 열성경련 군에서 39%로 대조군의 28%에 비해 많았으나 의미 있는 차이는 없었다. 평균 적혈구 용적, 평균 적혈구 혈색소는 열성경련 군에서 높았으나 차이는 없었고, 열성경련 군에서 평균 적혈구 혈색소 농도는 의미 있게 높고 적혈구 분포 폭은 낮았다. 단순 열성경련 군과 복합 열성경련 군 사이에는 혈액학적 소견의 차이는 없었다. 단변량 분석에서 P 값 0.010 미만인 몇가지 인자들의 다변량 로지스틱 회귀분석을 시행한 결과 열성경련 군에서 빈혈의 빈도가 의미 있게 높았다. 결 론 : 열성경련과 철 결핍 빈혈이 상호 관련성이 비록 단변량 분석 시에는 의미가 없었으나 다변량 분석에서 밀접한 관련성을 보여 주어 열성경련의 재발이나 악화를 막기 위해 적극적인 빈혈에 대한 평가와 치료가 필요할 것으로 사료된다.
