Food allergy refers to an immunologically mediated adverse reaction to food, mainly to proteinaceous constituents. Health implications vary between those individuals who experience mild physical discomforts to those with fast-acting, life-threatening anaphylactic reactions. The prevalence of food allergy is higher in children than in adults, estimated around 4-8% and 1-2% respectively in developed countries. Food allergy has no effective cure at the present time and total avoidance of causative foods is the most reliable prophylactic method currently recommended by the medical community. To help food allergic patients to make informed choices of their foods, mandatory labeling of selected food allergens has been introduced in several countries. All food allergen labelling provisions specify a set of allergens common to the regulated countries. Policy divergence, however, exists between countries by inclusion of additional allergens unique to specific countries and enforcement of specific labelling requirements. Such variations in food allergen labelling regulations make it difficult to manage allergen labeling in imported pre-packaged food products. This paper addresses two current issues in food allergen regulation: 1) an urgent need to determine true prevalence of food allergy in the Asia-Pacific region. This will enable refinement to the food allergen regulation to be more country-specific rather than simply adopting CODEX recommendations. 2) There is an urgent need for harmonization of food allergen regulation in order to prevent food allergen regulation becoming a trade barrier.

표고버섯에는 다양한 효능성분들이 존재하며 특히, β-glucan과 polyphenol 성분들은 항산화, 광노화, 주름개선 등의 피부개선 효능이 알려져 있다. 본 연구에서는 표고버섯 물 추출물에서 polyphenol과 β-glucan 함량을 확인하였으며 이러한 연구결과를 바탕으로 피부노화 억제효능을 조사하였다. Scratch wound healing assay를 통해 표고버섯 물 추출물 처리시 자외선 조사에 의해 손상된 HaCaT cell의 증식 유도 효과를 확인하였다. 또한 세포 내 생성된 ROS를 효과적으로 소거함으로써 세포 내 과도한 산화 스트레스를 줄여 다양한 염증성 사이토카인의 유발을 억제하고 피부노화 인자의 발현을 억제하는 것으로 생각된다. 세포 외 기질과 단백질을 분해하는 MMPs의 발현양상을 확인한 결과 표고버섯 물추출물은 MMP-1과 MMP-9의 발현을 억제하였으며, type I collagen의 생합성을 증가시켰다. 이를 통해 표고버섯 물 추출물은 세포를 활성화시켜 세포의 이동 및 증식을 유도함으로써 피부를 재생 및 collagen 합성을 촉진하고 collagen 분해 인자를 억제시킴으로써 피부의 주름억제 활성에 효능을 가지는 것으로 확인되었다. 따라서 본 연구를 통해 표고버섯 물 추출물은 화장품 분야에서 피부 노화 예방 및 개선소재로서의 개발 가능성을 확인하였다.

This study aims to research on the actual state of the ways that the aged people live in Seoul use intentionally or unintentionally to maintain in their health. The aged people selected randomly for the study are 541 men and 902 women who are all more than 65 years old. This survey carried out from April to May in 1980. The results of this study are summed up as follows: 1. The main means of making a living engage was agriculture with the per cent of 57. 3 and next was commerce (11.9%). 2. As for their staple foods, the majority of them eat mixed food of rice and barley, and the rest eat rice or minor-grain mixed rice. As subsidiary foods, vegetables are the most common side dishes (68.9%) and see-weeds (6.7%) are taken by the minority of them. 3. Most of them (74.6%) frequently or occasionally take special health foods to maintaing their health. The most common health food turned out to be tonic liquor to men, while honey to women. 4. The majority of them(23.2% of men and 45.5% women) refrain from drinking and smoking. 5. 39.5 per cent of men and 25.5 per cent of wome) take light exercise such as going up hill and walking. 6. The majority of them undergo routine health check with the per cent of 10.8 or occasioanal health check with the 42.9. As medical treatment, many of them(45.9%) take Chinese remedies, western remedies(39.1%) and folk remedies (15.0%). 7. Many of them (66.0%) feel subjective symptoms about some geriatric diseases such as neuralgia, hypertension and cough. 8. Many of them (63.2%) free from mental trouble, while 17.7 per cent of them appeal to no job to do, 10.0 per cent of alienation and 9.1 per cent of domestic troubles. 9. Their subjective judgements of their secrets of health and longevity attach more importance to leading a regular life. 10. Most of them want to be served appropriate medical care, rest place, health consultations, etc. All these results reveal that health and longevity of the aged people are maintained by necessary cares and efforts, not by accident nor by apathy.

Inhibiting the bioactivities of circulating endothelial progenitor cells (EPCs) results in significant inhibition of neovessel formation during tumor angiogenesis. To investigate the potential effect of phloroglucinol as an EPC inhibitor, we performed several in vitro functional assays using $CD34^+$ cells isolated from human umbilical cord blood (HUCB). Although a high treatment dose of phloroglucinol did not show any cell toxicity, it specifically induced the cell death of EPCs under serum free conditions through apoptosis. In the EPC colony-forming assay (EPC-CFA), we observed a significant decreased in the small EPC-CFUs for the phloroglucinol group, implying that phloroglucinol inhibited the early stage of EPC commitment. In addition, in the in vitro expansion assay using $CD34^+$ cells, treatment with phloroglucinol was shown to inhibit endothelial lineage commitment, as demonstrated by the decrease in endothelial surface markers of EPCs including $CD34^+$, $CD34^+/CD133^+$, $CD34^+/CD31^+$ and $CD34^+/CXCR4^+$. This is the first report to demonstrate that phloroglucinol can inhibit the functional bioactivities of EPCs, indicating that phloroglucinol may be used as an EPC inhibitor in the development of biosafe anti-tumor drugs that target tumor angiogenesis.

Objectives: This systematic review of cohort studies aimed to identify any association between specific dietary patterns and risk of colorectal cancer (CRC). Dietary patterns involve complex interactions of food and nutrients summarizing the total diet or key aspects of the diet for a population under study. Methods and materials: This review involves 6 cohort studies of dietary patterns and their association with colorectal cancer. An exploratory or a posteriori approach and a hypothesis-oriented or a priori approach were employed to identify dietary patterns. Results: The dietary pattern identified to be protective against CRC was healthy, prudent, fruits and vegetables, fat reduced/diet foods, vegetables/fish/poultry, fruit/wholegrain/dairy, healthy eating index 2005, alternate healthy eating index, Mediterranean score and recommended food score. An elevated risk of CRC was associated with Western diet, pork processed meat, potatoes, traditional meat eating, and refined grain pattern. Conclusion: The Western dietary pattern which mainly consists of red and processed meat and refined grains is associated with an elevated risk of development of CRC. Protective factors against CRC include a healthy or prudent diet, consisting of vegetables, fruits, fish and poultry.

Objectives: The purpose of this study was to examine the relationship between dietary habits and concentrations of urinary phthalate metabolite in elementary school children. Methods: This study was conducted in Seoul, South Korea. We collected urine samples from 156 children from a single school in September 2016. Information on dietary habits was obtained from the parents of the children. Five types of urinary phthalate metabolites were analyzed using a high-performance liquid chromatography tandem mass spectrometer. Multiple linear regression analysis was used to determine the factors affecting the concentrations of urinary phthalate metabolite. Results: Girls had a significantly lower concentration of urinary mono-n-butyl phthalate (MnBP) (p=0.006) than did boys. When the consumption of bean processed food and wrapped delivery food were more than once a week, urinary MnBP (p=0.021) and monobenzyl phthalate (MBzP) (p=0.032) concentrations were the highest, respectively. Conclusion: Several urinary phthalate metabolite concentrations were associated with demographic and dietary habits. Particularly, urinary MnBP and MBzP were associated with several processed foods. The findings of this study might be useful as basic data for establishing and educating on environmental health policy.

Purpose: This study was conducted to analyze the change in the obesity index in girls receiving a gonadotropin-releasing hormone agonist (GnRHa), based on treatment duration, and to aid in nutritional counseling by investigating dietary habits and lifestyle. Methods: Anthropometric examinations were conducted on 62 girls treated with GnRHa from January 2010 through July 2014. Parents were asked to fill out questionnaires on patient dietary habits and lifestyle. Results: The group taking GnRHa for over 1 year had a higher rate of obesity increase than the group taking GnRHa for less than 1 year, but they had common habits related to obesity, which should be corrected. In addition, 69.2% of the normal weight group taking GnRHa for over 1 year gained weight, and needed more intensive programs, which include physical exercise and nutritional education. Although girls with precocious puberty showed a decrease in the intake of high-calorie foods with nutritional intervention regardless of treatment duration, they still had problems that needed improvement, such as shorter meals and lack of exercise. Conclusion: Girls with precocious puberty and their parents should emphasize maintenance of proper body weight, especially when treatment for over 1 year is anticipated. Consistent education in nutrition, ways to increase intensity and duration of physical activity, and the need to slow down mealtimes are important in managing obesity; doctors need to perform regular checkups and provide nutritional counseling.
