This study investigated the anti-obesity effects of lactic acid bacteria ferments cultured in industrial medium with ethanol extract of ramie leaf (Boehmeria nivea L.). On the 4th day of fermentation, the maximum live cell counts were 8.75-8.85 log CFU/mL, pH was 3.74-3.79, and total acidity was 2.07-2.19%. The fermentation of lactic acid bacteria on the fourth day resulted in the amount of lactic acid reaching 1,676.03-1,910.12 mg%. The lipase inhibitory activities of Lactiplantibacillus plantarum (L. plantarum) JBLAB0101 (FRLPLA) and Lactobacillus rhamnosus GG (LGG, (FRLLGG)) ferments were 30.10%, and 25.63%, respectively, at a concentration of 0.5 mg/mL. The lipid accumulation, leptin production, PPAR-γ and SREBP-1c mRNA levels were decreased to 37.54%, 54.64%, 24.18%, and 31.32%, respectively, at 200 ㎍/mL concentration of FRLPLA. These results suggest that anti-obesity effect could be increased by lactic acid bacteria in industrial medium with extract of ramie leaf.

Ground beef에서 처음으로 분리된 conjugated linoleic acid (CLA)는 mouse epidermal carcinogenesis, mouse forestomach tumor, rat mammry carchnogenesis 및 colon carcinogenesis를 억제하는 항암성 효과를 지니고 있다. CLA는 항암성뿐만 아니라 anti-atherosclerosis, immune function과 항산화성 등의 생리활성 효능이 있는 것으로 밝혀졌으며, CLA의 주요 source는 반추동물에서 유래된 meat, 우유 및 유제품이며 일반 식물성유에도 미량으로 존재한다. 최근 국내외에서 CLA를 이용한 기능성 meat 및 식품을 생산하기 위한 연구가 수행되고 있다. 본 발표에서는 CLA에 관한 간단한 review와 본 연구진의 연구결과를 소개하고자 한다.

최근 20여년 동안 Panax ginseng의 다양한 효과가 연구 되어져 왔다. Panax ginseng의 주요 활성 성분인 ginsenosides는 오직 인삼에서만 발견되어지는 saponin이다. 최근 들어 신경, 非신경 또는 복합적으로 분포된 세포에서 ginsenoside가 $Ca^2+$, $K^+$,$Na^+$,$Cl^-$ channel이나 ligand gated ionchannel (5-HT3, nicotinic acetylcholine, NMDA receptor)과 같은 다양한 ion channel을 조절하는증거들이 발표되고 있다. Ginsenoside는 voltage-dependent $Ca^2+$, $K^+$,$Na^+$ channel의 활성을 억제하는 반면 $Ca^2+$-activated $Cl^-$ channel이나 $Ca^2+$-activated $K^+$ channel의 활성은 증가 시키는 것으로 나타났다. 또한 흥분성 ligand-gated ion channel인 $5-HT_3$, nicotinic acetylcholine, NMDA receptor의 활성은 억제한다. 본 총설에서는 현재까지 알려진 ion channel 활성에 대한 ginsenoside의 조절작용과 이것으로 인해 어떻게 생물학적 효능과 연결이 되어있는지에 대하여 이야기하고자 한다.

Wrinkle formation and dryness are the most well-known symptoms of skin aging. This study investigated skin anti-aging and moisturizing effects of Mugunghwa (Hibiscus syriacus L.), the national flower of Korea. The effect of H. syriacus L. flower extract was examined in skin cells originating from humans in vitro and in hairless mice exposed to UVB in vivo. The in vivo study results showed that skin hydration-related factors such as involucrin, filaggrin, HAS1, HYAL1, and matrix metalloproteinase-I (a primary skin photoaging factor) were regulated by H. syriacus L. Additionally, epidermal thickness and collagen disruption, which resulted in wrinkle formation and skin dryness, were ameliorated by oral administration of H. syriacus L. These results indicate that H. syriacus L. flowers can play important roles in preventing aging and promoting skin moisturizing.

The purpose of this study was to find a relationship between eating behavior, dietary self-efficacy and nutrition knowledge by comparing these items in elementary school students according to food service type. The survey was made through a questionnaire from 759 students in the 6th grade of elementary school in 39 Gangwon Province. The average score of eating behaviors according to food service type was highest for urban type, followed by agri-fishery type, and finally remote island and country type, for the questions asking about the application of nutrition knowledge and the frequency of eating out. The average score of nutrition knowledge according to food service type showed significant differences for the questions about eating snacks before going to sleep and weight increase as well as calorie comparisons between foods. For the correlation of eating behavior, dietary self-efficacy and nutrition knowledge, the agri-fishery type showed positive in all of the three items with significant differences. In the remote island and country type, there was a positive relationship between nutrition knowledge and dietary self-efficacy, and between eating behavior and dietary self-efficacy. However, there was no significant difference of correlation between nutrition knowledge and eating behavior. In order to confirm the predictable variables for eating behavior, a regression analysis was made by injecting variables in every stage with independent variables of dietary self-efficacy and nutrition knowledge, which showed a significant relationship with eating behavior. The results showed that, in the urban type, dietary self-efficacy and nutrition knowledge affected the eating behavior and, in the agriculture type and the remote island and country type, only dietary self-efficacy affected the eating behavior.

This research was planned and executed to evaluate how the composition of Yak-sun (oriental diet therapy) can effect health conditions of people who are suffering from diet-related diseases like obesity and hyper lipidemia by taking Yak-sun in a form of nutritional supplement with our daily meals. We produced Yak-sun tea with $Ky\hat{a}lmy\hat{a}ngja$, Kamguk, $K\hat{u}m\hat{u}nhwa$, Ch'onkung and observed nutritional composition and evaluated how this tea effects on serum lipids and homocystein concentration by clinical practices. With this observation, we found out that this tea has significant effect on increasing of HDL-cholesterol, decreasing of LDL-cholesterol and homocysteine concentration, and we think that scientific and objective evaluation was done on the components of Yak-sun tea prescription. We concluded that we could apply the components not only in a form of tea, but also in other forms of various food. The information we received from this conclusion will be a basic information on how we can apply oriental medicinal resources into other food and will also be a stepping stone for medicinal herbs to step foot in the field of functional food research, which already draws sizable attention world-wide.

4차 산업시대로의 진입과 함께 인구 고령화 현상이 지속되면서 정보, 의료, 식품 분야 등의 역할이 중요해지고 있다. 특히 건강한 삶을 영위하기 위해 식품과 의료가 융합한 식치 정보에 대한 사람들의 관심과 필요성이 증가하고 있는 것에 비해 이에 대한 연구는 부족한 실정이다. 따라서 본 연구는 식품과 한의 정보를 수집하고 융합하여 식품 또는 식재료의 영양, 성질, 효능, 질병 등이 결합된 하나의 식치 데이터를 시스템 상으로 구축하고자 하였다. 이를 위해 고조리서, 한의서, 역사서 등의 고문헌과 논문, 특허 등의 현대 과학적 연구 자료를 수집하였으며, 수집된 자료들을 일정 기준에 따라 분류하고 코드화 하였다. 이후 정제된 각각의 데이터들 간의 연관성을 파악하고 연결 지어 식품과 한의 정보가 통합된 하나의 새로운 식치 데이터를 구축하였다.
