Objectives : To observe the changes in the serum proteins after intravenous injection of cultivated wild ginseng pharmacopuncture. Methods : Blood was collected before and after the administration of cultivated wild ginseng pharmacopuncture and only the serum was taken. Then differences in the spots on the scanned image after carrying out 2-Dimensional electrophoresis were located and conducted mass analysis and protein identification. Results : Following results were obtained from the comparative analysis of serum proteins before and after the administration of cultivated wild ginseng pharmacopuncture. 1. 28 spots were identified before and after the administration. 2. In confirming manifestation degree, spots with more than two-times increase were 204, 1302, 2205, 3105, 7104, 8006, spots with more than one-time increase were 1101, 1505, 2013, 2403, 3009, 3010, 4002, 4009, 6704, 8101, and spots with decrease were 205, 801, 803, 3205, 5202, 6105, 6106, 7103, 9001, 9003. 3. After conducting protein identification, proteins 205, 804, 1302, 4009, 6105, 6106 are unidentified yet, and 1l01 is unnamed protein. Protein 204 is identified as complement receptor CR2-C3d, 801 as YAPl protein, 803 as antitrypsin polymer, 1505 as PRO0684, 2013 and 3010 as proapolipoprotein, 2205 as USP48, 2403 as vitamin D binding protein, 3009 as complement component 4A preprotein, 3105 as immunoglobulin lambda chain, 3205 as transthyretin, 4002 as Ras-related protein Ral-A, 4204 as beta actin, 5202 and 7104 as apolipoprotein Ll, 6704 as alpha 2 macroglobulin precursor, 7103 as complement component 3 precursor, 8006 as testis-specific protein Y, 8101 as transferrin, 9001 as (Alpha-Oxy, Beta-(Cl12g)deoxy) T-State Human Hemoglobin, and 9003 as human hemoglobin. 4. Immune protein CR2-C3d(204), which acts against microbes and pathogenic organisms, was increased by more than two-times after the administration of pharmacopuncture. 5. Antitrypsin(803), which is secreted with inflammatory response in the lungs, was reduced after the administration of pharmacopuncture. 6. Proapolipoprotein(2013, 3010) and apolipoprotein(7104), key components of the HDL-cholesterol which plays an important role in preventing arteriosclerosis, were increased after the administration of pharmacopuncture. 7. Vitamin D binding protein(DBP, 2403), protecting the lung at the time of inflammatory response, was increased after the administration of pharmacopuncture. 8. Transthyretin(TTR, 3205), which is the main protein causing familial amyloid polyneuropathy(FAP), was decreased after the administration of pharmacopuncture. 9. Ras-related protein Ral-A(4002) that controls phospholipid metabolism, cytoskeletal formation, and membrane traffic, was increased after the administration of pharmacopuncture. 10. Testis-specific protein Y(8006), which takes part in determination of the gender, was increased by more than two-times after the administration of pharmacopuncture. 11. Transferrin(8101), which balances the iron level in the body, was increased after the administration of pharmacopuncture. Conclusion : Above results support the notion that intravenous injection of cultivated wild ginseng pharmacopuncture induce changes in serum proteins and this research can be a pioneer work in finding biomarkers.

Objective: Chronic obstructive pulmonary disease(COPD) is characterized by persistent airflow limitations associated with chronic inflammatory response due to noxious particles or gases in the lung. Iron deficiency is associated with chronic inflammation, such as COPD. The aim of this study was to evaluate the relationship among iron deficiency, iron homeostasis, and inflammation in retired miners with COPD. Methods: The serum levels of ferritin, soluble transferrin receptor(sTfR), and transferrin saturation(TSat) as biomarkers for iron deficiency and high-sensitivity C-reactive protein(hsCRP) as a biomarker for inflammation and hepcidin as a biomarker for iron homeostasis were measured in 93 male subjects. Iron deficiency was defined as any one or more of (1) sTfR>28.1 nmol/L, (2) TSat<16%, and (3) ferritin< $12{\mu}g/L$. Results: Iron deficiency was found 28% of the study subjects. Median levels of serum hsCRP was significantly increased related to airflow limitation of COPD(GOLD 1, $0.09{\mu}g/dL$ vs. GOLD 2, $0.17{\mu}g/dL$ vs. GOLD $3{\leq}$, $0.30{\mu}g/dL$, p=0.010), and was positively correlated with hepcidin(p=0.009). Mean level of serum hepcidin was lower in COPD subjects with iron deficiency(p=0.004) and serum levels of hepcidin was negatively correlated with %$FEV_1$ predicted(p=0.030). Conclusions: These results suggest that high serum levels of hepcidin are related to severe airflow limitation or inflammation and can decrease iron availability, regardless of iron status.

This study was performed to investigate the effect of sources of protein on iron bioavailability in 10 healthy young Korean women. The 18-day metabolic study consisted of a 6-day adaptation period, 6-day moderate protein(60g protein/day, 18mg Fe/day) and 6-day high protein period(90g protein/day, 18mg Fe/day). During the moderate and high protein period, 5 subjects were fed the high plant protein meals(80% plant protein). Fecal excretion of dietary iron was significantly higher(p<0.05) in high protein high plant diet group(HPP, 9.48$\pm$1.61mg/day) than in high protein high animal diet group (HPA, 14.40$\pm$0.89mg/day). Apparent absorption and bioavailability of iron was also significantly higher(p<0.10) in HPA(40.7$\pm$5.3%, 6.46$\pm$1.61mg/day) than in HPP(14.4$\pm$5.3%, 2.39$\pm$0.89mg/day). But there was no significant difference between the high animal protein group and high plant protein group in moderate protein period. Serum iron concentration and transferrin saturation increased as animal protein intake increased, from 106.0$\pm$5.1ug/이 and 30.6$\pm$1.5% for MPA to 129.1$\pm$6.7ug/이 and 37.1$\pm$1.3% for HPA. Statistically positive correlations were shown not only between the level of dietary heme iron and apparent absorption(r=0.95, p<0.05), but also between serum iron concentration and apparent absorption(r=0.64, p<0.05). Negative iron balance was shown in two subjects fed the moderate protein meals. These results suggest that recommanded dietary allowances of iron may be under the need to maintain the positive balance, and iron bioavaliability increase by only high level of animal protein intake.

To investigate the effects of dietary phytate reduction and zinc supplementation on biochemical iron parameters in elderly Korean women consuming inadequate iron, fifteen healthy women aged 64-75 years were recruited for a feeding study. A high-phytate diet (27.8 phytate:zinc molar ratio) was provided for 9 days, followed by a nine-day low-phytate diet(12.3) and a subsequent 28-day period of unregulated meals with zinc supplementation (22 mg/d as zinc gluconate). Serum iron increased significantly with the low-phytate diet (130.4 $\mu g$/L) but returned to the level observed during the high-phytate diet (113.0 $\mu g$ /L) period when subjects were taking zinc supplements (105.8 $\mu g$ /L). However, serum ferritin in the subjects decreased significantly with the low-phytate diet (73.8 $\mu g$ /L) as well as with zinc supplementation (57.2 $\mu g$ /L), compared to levels following consumption of the high-phytate diet (89.6 $\mu g$ /L). Transferrin receptor and transferrin saturation were unchanged with the treatments. In summary, zinc supplementation might result in deteriorated iron status in elderly Korean women who consume inadequate iron, while there was no significant effect from reducing dietary phytate.

This study was carried out to evaluate the iron nutrition status of 212 middle school students(106 males and 106 females) residing in Seoul(13-14 years old ) using eating patterns and a measurement of anthropometrical determination and hematological indices. Fasting blood samples were taken from all subjects, serum iron (SI) and total iron binding capacity(TIBC) concentrations were measured, and transferrin saturation(TS) levels were calculated. Iron and other nutrient intakes were estimated by a semi-quantitative frequency questionnaire. The level of TS(%) which was calculated with TIBC and SI in females(20.4$\mu\textrm{g}$/dl) was significantly lower(p<0.050 than that of males (27.4$\mu\textrm{g}$/㎗). The prevalence of iron deficiency was found to be 36.7% when defined by TS(%) (<05%). Mean daily intake of total iron in the study subjects was 14mg and heme iron intake was 5.4mg(38.1%) . There was a significant negative correlation between the level of SI and the income level and a positive correlation with the level of TIBC and the income level. TIBC had a positive correlation with the anthropometric variables(Ht, Wt, BMI, RI and PIBW). SI and TS had a negative correlation with body fat percentage. There was a positive correlation between energy intake and TIBC only among females. The logistic regression analysis revealed that income level, body fat percentage , weight and energy intake were major determinants of low SI levels. Among the determinants of abnormal TIBC levels were weight , height, income level and energy intake. Finally , among those of low TS% were iron and energy intake and income level. These observations suggest that physical status, body fat percentage energy and iron intakes and income level are risk factors for iron-deficiency anemia among the middle school students in Seoul.

The objective of this study was to investigate the effects of iron supplementation and nutrition education on the iron status and anemia of middle school girls in Ulsan city in Korea. The subjects were already diagnosed as having anemia (hemoglobin < 12 g/dL) or iron deficiency (ferritin < 12 ng/mL and/or transferrin sataturation < 14 %). Over a period of three months, one iron tablet (80 mg Fe as ferrous sulfate/day) was administered to the iron deficient subjects and two tablets (160 mg Fe as ferrous sulfate/day) were administered to the anemia subjects. Total calorie intake of subjects was 82.1 % of RDA. The iron intake of subjects was 91.3 % of RDA and the Ca intake was 78.8 % of RDA. The basal hemoglobin concentration of subjects averaged 12.8 1.2 g/dL, and this increased significantly (p < 0.001) to 13.2 0.9 g/dL after iron supplementation. The basal ferritin concentrations were 14.9 14.2 ng/mL and these significantly increased to 26.6 19.8 ng/mL (p < 0.001). The level of total iron binding protein (TIBC) significantly decreased from the initial 523.1 108.7 $\mu\textrm{g}$/dL to 462.2 90.2 $\mu\textrm{g}$/dL (p < 0.001) after iron supplementation. Anemia symptoms such as‘Being bruised easily’, ‘Inflamed inner mouth’, and ‘Pale face’ improved significantly after iron supplementation in the subjects. There was a negative correlation between their class & year ranking and serum iron level, transferrin saturation after nutritional education and iron supplementation. It was shown, therefore, that the higher the improvement of their anemia level after iron supplementation, the higher their academic performance. It was shown that there was some improvement of their dietary attitudes after nutritional education, and that their serum level related to anemia symptoms and iron nutrition was improved after iron supplementation.

The purpose of this study was to investigate the nutritional status before and after gastrectomy of gastric cancer patients in Jeonbuk Province. The subjects were 136 patients with gastrectomy of gastric cancer. We assessed the nutritional status before and after an operation by general characteristics (age, clinicopathological stage, type of operation, method of reconstruction), anthropometric characteristics (height, weight, skeletal muscle mass, body fat mass, body mass index (BMI), percent body fat, arm muscle circumference AMC, arm circumference AC) and biochemical characteristics (hemoglobin Hb, hematocrit Hct, mein corpuscular volume MCV, mean corpuscular hemoglobin MCH, total lymphocyte count TLC, serum albumin, serum transferrin). Mean ages were 60.0 yrs in males and 58.8 yrs in females. Age, clinicopathological stage, types of operation and reconstruction methods were not significantly different between males and females. Weight, skeletal muscle mass, body fat mass, BMI, percent body fat, AMC and AC significantly deteriorated by gastrectomy. There were severe weight losses in males and females after gastrectomy. Hemoglobin, Hct, MCV, MCH, TLC, albumin and transferrin significantly deteriorated by gastrectomy. After gastrectomy, subjects who were assessed as malnounrished in Hb and Hct were increased in male and those who were assessed as malnounrished in Hb were increased in females. These results suggest that a nutrition intervention, specially for energy, protein and iron, is necessary to improve the nutritional status of gastric cancer patients with gastrectomy.

To evaluate the effectiveness of nutritional supplements for cancer patients, the study was performed in 30 cncer patients, receiving chemotherapy. Patients were randomly divided into two groups -15 patients for the nutritionally supplemented group and 15 patients for the control group. Patients of the supplemented group were nutritionally supported with a commercial product for 9 weeks. Nutritional status of the patients was detrmined by dietary intake data, anthropometric measurements and hematological analysis at the beginning and after 3, 6 and 9 weeks of supplemental priod. Mean daily intake levels of energy, protein, calcium, phosphorus, thiamin, riboflavin, niacin and asorbic acid for the supplemented group were significantly higher than those of control group. Significant increase in mid-arm circumference, triceps skinfold thickness and arm fat area were observed in supplemented group during the study period. However, the changes of body weight, body mass index and arm muscle area were not significantly increased. Serum transferrin level improved slightly by nutritioal support, but serum albumin levle did not change significantly. There data show that nutritional status of cancer patients receiving chemotherapy can be improved by utritional supplementation for 9 weeks.
