Purpose: Non-alcoholic fatty liver disease (NAFLD) in children has become an important public health issue because of its high prevalence and severity. Several noninvasive methods for estimating NAFLD are under investigation. We aimed to evaluate the usefulness of serum ferritin as a biomarker of severity of pediatric NAFLD patients. Methods: A total of 64 NAFLD patient were enrolled from Severance Children's Hospital from March 2010 to February 2013. Serum ferritin levels, liver related laboratory tests, liver magnetic resonance imaging (MRI) (2-dimensional [2D] proton density-fat fraction) and NAFLD severity markers were compared between obese group and overweight group. Correlation analyses were performed between serum ferritin and laboratory values including NAFLD severity markers. Results: In obese group, serum ferritin, alanine aminotransferase (ALT), total bilirubin, international normalized ratio (INR), MRI 2D proton density-fat fraction, aspartate aminotransferase (AST) to platelet ratio index (APRI) and fibrosis- 4 (FIB-4) (an index score calculated from platelet count, ALT, AST and age) were significantly higher than those of overweight group. NAFLD severity markers, APRI and FIB-4, and liver specific important laboratory values, AST, ALT, INR, cholesterol, triglyceride and low density lipoprotein show significant correlation with serum ferritin in NAFLD patients. Conclusion: Serum ferritin concentrations could be a candidate of useful severity marker in the pediatric NAFLD patients.

Total iron content and ferritin distribution have been determined in red pepper(Capsicum annuum L.) during development stage under conditions of iron nutritional status from hydroponic culture. Color of the leaves become chlorotic on iron deficient and high concentration. The plant height on each iron concentration had retarding effect at concentration lower than $25\muM$ and greater than 125$25\muM$. In normal green leaves. Total iron content was almost constant with a mean value of $2.5\mumole$ of iron/mg of dry matter, except at 63day, for which it increases slightly to $4\mumole$. Howere, iron content of chlorotic plants grew on iron free medium was not almost detectable. Also in post chlorotic leaves(++Fe), iron content was evidently increase unitl 7days after transfer on liquid medium, but decreased from after 14days. Also, ferritin protein analysed total protein extracts prepared from leaves of different ages using antibodies raised against ferritin protein. Ferritin protein deereased progressively during the first week of germination and was not detectable in vegetative tissues. Ferritin protein in post chlorotic leaves wasevidently strongly cnhanced until 11days after transfer on liquid medium but decreased until the leves became chlorotic.

This paper has studied the nutritional iron status of adults in the city of Taegu. The subjects of the experiment were twenty six men and women living in the city of Taegu. The iron intake was 26.1mg for men and 17.1mg for women, which were respectively 217.5% and 95% of RDA. For men heme iron was 5% and nonheme iron, 95% for women heme iron was 5.8% and nonheme iron, 94.2%. The absorption rate of dietary iron was 6.2% for men and 9.1% for women. The hemoglobin was 14.5g/dl for men and 11.9g/dl for women, and the rate of developing anemia was 8.3% in men and 57.1% in women. The serum ferritin was 57.8ng/ml with men, which was found to be normal, and 14.7ng/ml with women, which showed that 57.1% of women were in the condition of iron depletion or iron deficiency anemia. The rate of developing anemia resulting from the deficiency of serum ferritin was as high as that from the deficiency of hemoglobin. The correlation between iron intake based on the dietary record, and energy intake, vegetable protein intake and dietary fiber intake was found to be positive. So was the correlation between the iron intake, and hemoglobin, serum ferritin and urinary iron excretion. There was also a positive correlation between hemoglobin, and hematocrit and serum ferritin. The correlation between fecal iron excretion and serum ferritin was positive. Fecal iron excretion and urinary iron excretion can be complemented by iron intake but the fact should be considered that 95% of iron intake is nonheme iron, which is difficult to absorb. Based on the above-mentioned things, serum ferritin and hemoglobin can be used as the standards of measuring anemia. As women in their child bearing years show the high rate of 57.1% of developing anemia, the more thorough nutritional education of iron is required.

Purpose: Recently, the role of serum tumor marker has been studied for an important issue on diagnosing and treating tumors in the head and neck region because tests using tumor markers need relatively simple procedures and are acceptable to patients, compared with other test methods. Tumor marker tests were performed on patients with squamous cell carcinoma, which were known to have the highest prevalence among tumors in the head and neck region. Association between each tumor marker, and diagnosis and prognosis of tumors was assessed. Materials and methods: Tumor marker tests were carried out on 31 patients who visited Oral and Maxillofacial Surgery Department in Dankook University Dental Hospital between January 2003 and August 2008 and who were diagnosed as primary oral squamous cell carcinoma through out histopathologic diagnosis. Blood sample from these patients was performed to measure tumor markers using nuclear medicine diagnostic equipment. Measured entries were as follows: PSA(prostate-specific antibody), SCCAg( Squamous Cell Carcinoma Related Antigen), CA 19-9(Cancer Antigen 19-9), Ferritin, $\alpha$- FP(Alpha-Fetoprotein), Cyfra 21-1, CA125 (Cancer Antigen 125) and p53. Results: Analyses on each tumor marker indicated that squamous cell carcinoma in the head and neck region had statistically significant correlation with p53, SCC-Ag(TA-4), Cyfra 21-1 and Ferritin. p53 demonstrated the highest sensitivity. Especially, 4 cases among 18 cases which Ferritin was measured exhibited metastasis. In all those 4 cases, Ferritin values were higher than the standards (15 - 332ng/ml). Therefore, Ferritin is considered to have a close relation with metastasis of squamous cell carcinoma. Conclusion: This study shows that tumor marker tests are more useful in evaluating progression and prognosis of tumors rather than in diagnosing them. Particularly, serum Ferritin is considered to be beneficial in assessing metastasis of squamous cell carcinoma in the head and neck region and in developing treatment plans based on the assessment.

The purpose of this study was to assess the iron nutritional status and dietary iron availability of postmenopausal women residing in Jeonju area. The anthropometric parameters, nutrient intake and biochemical status of iron were measured from 57 postmenopausal women aged 50∼74 years old. Mean values of hemoglobin(Hb), hematocrit(Hct), serum iron(Fe), total iron binding capacity(TIBC) and serum ferritin(Ferritin) concentration were 12.82${\pm}$1.03g/dl, 37.68${\pm}$2.99%, 92.60${\pm}$46.66ug/dl, 353.0${\pm}$54.48ug/dl, 86.86${\pm}$100.7ug/ιrespectively. Prevalence of iron deficiency greatly varied by indices from 14.04% when judged by Ferritin(<20ug/ι) to 40.4% by TIBC(>360${\mu}$g/dl. The anemic subjects assessed with Hct percent(36%) represented 22.8%, whereas 21.1% of the subjects possessed less than 12g/dl of Hb. Ferritin concentration showed a significantly negative correlation with TIBC(r=-0.343, p<0.01) and a positive correlation with MCHC(r=0.361, p<0.01). The mean daily intake of iron was 10.62mg and intake of heme iron was 5.3%(0.56mg) of total iron intake. Total absorbable iron caculated by the method of Monsen was 0.49mg anti bioavailability of dietary iron was 4.61%. Ferritin Concentration was positively associated with total iron intake(r=0.264, p<0.05), dietary nonheme iron(r=0.286, p<0.05) and iron of animal food (r=0.364, p<0.01). But Ferritin concentration was not correlated dietary heme iron(r=-0.137, p>0.05). Major food groups of iron intake were vegetables(20.15%), cereals(19.59%) and fishes(12.34%) in postmenopausal women. Intake of eggs was positively associated with Ferritin(r=0.473, p<0.01).

BACKGROUD/OBJECTIVES: Obesity is globally a major public health issue. Evidence suggests that elevated ferritin levels are associated with obesity, dyslipidemia, insulin resistance, and metabolic syndrome. This study was undertaken to examine the relationship between the serum ferritin level and depression in Korean male adults with respect to classification of the prevailing obesity. SUBJECTS/METHODS: This was a case-control study; subjects were classified into obese group (${\geq}25.0kg/m^2$, 28 subjects) and normal group ($18.5-22.9kg/m^2$, 27 subjects). A survey was conducted to assess the depression levels as per the guidelines suggested by the Center program for Epidemiological Studies-Depression (CES-D). Blood was collected from each group for assessing biomarkers, and isolated plasma was evaluated for fasting glucose, insulin, quantitative insulin sensitivity check index, and ferritin levels. Data were analyzed, and groups were compared with respect to Body Mass Index (BMI), depression scale and biomarkers. RESULTS: The average depression score of the obesity group was 16.86, which was higher than the normal group (12.56). Subjects scoring more than 16 points comprised 53.6% of the population in the obese group, which was more than double that in the normal group, as assessed by the CES-D program. Furthermore, the serum ferritin level of the obesity group was 207.12 ng/mL, which was higher than that of the normal group (132.66 ng/mL). Lastly, the BMI appeared to be significantly correlated with both depression (r = 0.320, P = 0.017) and elevated ferritin levels (r = 0.352, P = 0.008). CONCLUSION: This study provides evidence of existing correlation between ferritin and depression with obesity.
