1.Pharmacometabolomics: Current Applications and Future Perspectives.
Translational and Clinical Pharmacology 2014;22(1):8-10
Metabolomics, a novel "omics" platform, is a powerful tool for the discovery of clinically useful biomarkers and biochemical processes to improve diagnosis and therapy. Through the use of advanced analytical technologies, metabolomics enables the assessment of comprehensive metabolic profiles that are affected by both genotype and environmental factors. Recently, attention has been focused on the concept of pharmacometabolomics, an emerging field that is derived from metabolomics. Pharmacometabolomics is focused on the use of individual metabolic signatures for the prediction and evaluation of drug efficacy and safety, eventually accelerating clinical pharmacology toward personalized drug therapy.

To determine the impact of intake large amount whole cow's milk (WCM) on iron status during early childhood (18~36 months), selected indices of complete blood count(CBC) and iron status were compared between the WCM large amount intake group (n=20)and small amount intake group (n=20). WCM large amount intake children's mean hemoglobin and mean hematocrit were 9.6+/-1.7 g/dL and 30.8+/-4.5% respectively. These range of peripheral blood with other indices of CBC disclosed the hypochromic microcytic anemia. WCM large amount intake children's some indices of CBC-hemoglobin, hematocrit, MCV, MCH-were significantly lower than those of small amount intake children (P<0.01). WCM large amount intake children had significantly lower mean iron, transferrin saturation and ferritin (P<0.01) and greater mean total iron binding capacity (P<0.05) than did small amount intake children. It is concluded that intake large amount of WCM for long duration impacts on the iron status of 18~36 months old children disadvantageously. It should be avoided for the protection of irreversible recognitive impairment and behavioral change.

4.The Factors Influencing on Health Promotion Behavior in Low-Income Vulnerable Elementary Students.
Journal of Korean Academy of Community Health Nursing 2008;19(2):167-176
PURPOSE: The goal of this study was to find out factors influencing the health promotion behavior of low-income vulnerable 4th, 5th and 6th-grade elementary school students. The specific goals were: first, to find out difference in health knowledge, self-esteem and health promotion behavior according to general characteristics; second, to investigate the correlations among health knowledge, self-esteem and health promotion; and, third, to analyze factors influencing health promotion behavior. METHODS: The subjects of this study were 137 low-income vulnerable 4th, 5th and 6th-grade elementary school children who were participating after-school programs in Seoul. RESULTS: Statistically significant differences were observed in health knowledge, self-esteem and health promotion behavior between girls and boys. In the sub categories, differences were observed in personal hygiene and health responsibility, stress management and personal relationship. The correlation of health promotion behavior with self-esteem and health knowledge was statistically significant. Regression analysis revealed that the influencing factor is self-esteem with the other variables under control. CONCLUSION: Health promotion education requires low-income vulnerable elementary children to increase their self-esteem. We recommend that it should be one of the most effective ways to split boys and girls to educate them in disparate classrooms.

6.Fatty acid oxidation disorders.
Hanyang Medical Reviews 2005;25(3):79-91
Inborn errors of fatty acid mitochondrial oxidation (FAOD) have drawn considerable attention in recent years because of rapid pace of discovery of new defects and an ever-increasing spectrum of clinical phenotypes. This review describes a clinical and biochemical phenotypes, diagnosis and treatment of FAOD. Some of FAOD can not be detected by conventional biochemical investigations, even when a patient is symptomatic with fasting intolerance or functional failure of fatty acid dependent tissue (s). Diagnosis must ultimately be based on direct assay of the involved enzyme, however, preliminary indicators may come from determination of carnitine and intermediate metabolites in plasma, profiling of urine organic acid, and radioisotopic screening assays with lymphocytes or cultured fibroblasts. We are faced with the following major challenges: whether to include FAOD in newborn screening programs, the investigation of the rules played by individual disorders in maternal complication during pregnancy, sudden and unexpected death in early life, and pediatric acute/fulminant liver failure.

Intraventricular hemorrhage is a common hemorrhagic cerebral disorder in premature, but occurs much less frequently in the full-term newborn. In order to obtain documentation of clinical and ultrasonographic characteristics of intraventricular hemorrhage in full-term, we performed cerebral ultrasonography on 602 newborn infants who had been admitted to neonatal intensive care unit at the Deppartment of Pediatrics, Yonsei University College of Medicine between December 1989 and June 1991. 15 cases (2.5%) of intraventricular hemorrhage were analysed. The results were as follows: 1) Among 15 cases with intraventricular hemorrhage, there was no obstetrical and perinatal complication in 8 cases (53%) and 13 cases (87%) were neurologically normal at birth. 2) Sudden onset of dramatic neurologic abnormalitis inclued seizures, fever, bulging fontanel, irritability, lethargy, vomiting in cases (73%) and the remainder (27%) had no clinical symptoms and signs. 3) The age at diangosis of hemorrhage was before 72 hours in 5 cases (33%), between 4 and 7 days in 2 cases (13%), at 8 to 28 days in 8 cases (53%), 8 of 15 cases (53%) had Grade 1 IVH, four with Grade 2, cases with Grade 3, and 1 case of these infant demonstrated Grade IV IVH. The source of hemorrhage was subependymal germinal matrix in 12 cases (80%) and choroid plaxus in 3 cases (20%). 4) Precipitating factors were cerebral venous infarction in 7 cases, hypoxic injury in 5, and 3 other infants had no identifiable medical risk factors. 5) Among all 15 survivors, 2 of 3 infants with choroid plexus hemorrhage required placement of a ventriculo-peritoneal shunt, in the other case, ventriculomegaly decreased spontaneously.

We report a case of porokeratotic eccrine ostial and dermal duct nevus in a 28-year old man. The skin lesions, present since birth, were multiple keratotic papules and punctate pits on the palms, soles and heels bilaterally. Histopathologically, the lesion was characterized by dilatation and hyperplasia of the eccrine sweat ducts with parakeratotic plugs related to sweat gland pores. This entity should be considered the differential diagnosis of other types of porokeratosis and comedo-like keratosis on palms and soles.

PURPOSE: The purpose of this study was to measure the level of job stress and health status and find out factors affecting the health status among circulation enterprise workers. METHOD: This study was a cross-sectional descriptive study. The subjects were 128 workers whose mean age was 33.2 years. Korean occupational stress questionnaire Short Form was used to measure job stress. Todai Heath Index that was made by Aoki in 1977 and translated by Kim(1997) was used to measure the health status. RESULTS: The total job stress scores of men and woman fell in the lower 50% of Korean workers. Job autonomy and interpersonal conflicts as a subcategories fell in upper level 50% in both men and women and job insecurity fell in the upper level 50% in women. The mean score of health status was 51.47, indicating slightly higher frequency of complains of health symptoms. There was no significant correlation between total job stress and total health status. Finally, factors influencing the health status were organizational system and age. CONCLUSION: Based on the results of this study, it is necessary to develop comprehensive stress management programs including interventions of personal and organizational levels for promoting workers' health.

We investigated the optimal culture conditions for Cryptosporidium muris in a human stomach adenocarcinoma (AGS) cell line by determining the effects of medium pH and of selected supplements on the development of C. muris. The optimum pH of the culture medium required for the development of C. muris was determined to be 6.6. The number of parasites significantly increased during cultivation for 72 hr (p < 0.05) at this level. On the other hand, numbers decreased linearly after 24 hr of incubation at pH 7.5. When cultured in different concentrations of serum, C. muris in media containing 5% FBS induced 4-7 times more parasites than in 1% or 10% serum. Of the six medium supplements examined, only 1 mM pyruvate enhanced the number of C. muris in vitro. Transmission electron microscopic observation showed the developmental stages of C. muris in the cytoplasm of the cells, not in an extracytoplasmic location. The growth of C. muris in AGS cells provides a means of investigating its biological characteristics and of testing its response to therapeutic agents. However, a more optimized culture system is needed for the recovery of oocysts on a large scale in vitro.
