  • 본 연구는 우리나라 식품첨가물공전의 18개유형과 72개 개별품목으로 구성된 합성착향료를 국내$\cdot$외 규정 및 관리제도를 고려하여 국제적 조화 및 안전성을 확보하고 이에 따른 최적의 관리제도를 마련하기 위해 수행되었다. 제외국의 합성착향료 관리제도와 안전성평가원칙을 검토하고 국내 착향료 관련 업체를 대상으로 제조현황, 이상적인 관리제도에 대해 설문조사를 실시하였다. JECFA와 FEMA에서는 합성착향료를 우리나라와는 달리 허용물질목록 (positive list)으로 관리하고 있으며 유럽과 일본 역시 이러한 체제로 전환할 예정인 것으로 나타나 이에 따른 국내 관리체제의 변화가 요구된다. 국내의 합성착향료 제조현황에 대해 설문지를 통해 조사한 결과, 수용성 향료는 음료에 많이 사용되고 있으며 주요 수입국가는 일본, 유럽, 미국의 순으로 나타났다. 합성착향료의 수입이나 제조시 가장 이상적인 관리제도를 묻는 의견에는 유럽과 Codex를 선호하는 것으로 나타났으며 국내에 적용하기에 가장 이상적인 관리방법에서도 유럽의 제도를 가장 이상적인 것으로 생각하는 것으로 나타났다. 식품첨가물공전 중 합성착향료의 허용물질목록화에 대해 조사대상기업의 $70\%$가 핀성하였으며 시행시기는 $44\%$가 제외국의 시행후가 가장 적절하다고 답변하었다. 상기 조사를 기반으로 현행 식품첨가물공전의 개별 및 유형별 관리체계를 허용물질목록으로 전환한 1800여 품목의 목록(안)을 제시하였다.

  • 쇠고기를 오존수(0.2 ppm)로 0, 5, 10, 30, 60분간 침수 처리하여 $5^{\circ}C$에서 24일 동안 저장하면서 3일 간격으로 쇠고기의 품질 측정 지표라 할 수 있는 휘발성 염기태질소(volatile basic nitrogen, VBN), 지방산패도(thiobarbituric acid reactive substances, TBARS), 산가(acid value, AV), pH 를 측정하여 오존수 처리가 냉장 저장중의 쇠고기의 품질에 미치는 영향을 평가하였다. 휘발성 염기태질소와 pH 변화를 측정한 결과 오존수 비처리구는 9일째 부패로 인정되는 수치가 측정된 반면 오존수(0.2 ppm)로 60분간 처리한 쇠고기에서는 15일까지 안전한 수치가 측정되었다. 지방산패도와 산가 또한 모두 오존수 처리한 쇠고기가 비처리구 쇠고기보다 낮은 측정치를 나타내었다. 본 실험의 내용을 종합한 결과 저 농도 오존수가 냉장 쇠고기 화학적 특성에 영향을 끼치며 저장성 향상에 효과적이라고 판단된다.

  • This study is peformed to investigate the effect of water extract from Vaccinium uliginosum L., on melanin production in B 16 melanoma cells, procollagen production and matrix metalloproteinase-1(MMP-1) inhibition in human fibroblast cells. One hundred grams of the Vaccinium uliginosum L. was extracted with 2000 mL of water($90^{\circ}C$, 16h, 2times). The water extracts were lyophilized and stored at $4^{\circ}C$ until used. Dry weight yields of extracts of Vaccinium uliginosum L. were $3\%$(w/w). Extracts from Vaccinium uliginosum L. showed scavenger activities on DPPH radical, superoxide anion radical, hydroxyl radical, hydrogen peroxide and singlet oxygen radical. And these substances inhibited release of cyiokines from human keratinocyte after UV B exposure. Therefore we confirmed that extracts from Vaccinium uliginosum L. had antioxidative effect. These substances inhibited purified tyrosinase activity and melanogenesis in B 16 melanoma cells treated/untreated IL-$1{\alpha}$. Moreover this extract stimulated procollagen production and inhibited MMP-1 production in human fibroblast cells treated/untreated IL-$1{\beta}$. Therefore we confirmed that extracts from Vaccinium uliginosum L. had whitening effect. And these substances decreased degree of wrinkle in hairless mouse skin that induced by UV B irradiation. Therefore we confirmed that extracts from Vaccinium uliginosum L. had anti-wrinkle effect. From the above results, it is possible that Vaccinium uliginosum L. may be developed to be an anti-melanogenesis agent and anti-wrinkle agent.

  • Acupuncture as a therapeutic intervention has been widely used for treatment for many functional disorders, such as substances abuse and mental dysfunction. In general, acupuncture is known to be simple, economic; painless, non-traumatic, and without untoward reaction, being able to inhibit the abstinence syndrome. Although a number of studies on acupuncture have been reported, a few studies described acupuncture effect on drug addiction. Evidences suggest that substances abuses including nicotine, cocaine and alcohol are in part related to its effects on dopamine neurons in the reward pathways of the brain. The effects of acupuncture on drug addiction may be mediated through the neuronal cells within the limbic structures, which are known to be involved in rewarding properties of drug abuse. This essay reviews clinical and experimental evidences for its effectiveness on the drug addiction, and discusses a plausible explanation for the mechanism of acupuncture on substances abuse.

  • Bone health is maintained by balance between bone resorption and bone formation, and bone homeostasis requires balanced interactions between osteoblasts and osteoclasts. Most of drugs and functional foods for bone health have been developed as bone resorption inhibitors, which maintain bone mass by inhibiting the function of osteoclasts. The recent studies have shown beneficial effects of marine natural products on bone health. Therefore, this review is aimed to study effects of marine-derived natural substances on osteoarthritis inhibition via attenuation of MMPs and osteoblastic differentiation via activation of alkaline phosphatase (ALP), osteoclacin (OC), bone morphogenic protein-2 (BMP-2) as an important factor for bone formation, and mineralization. The present review can provide new insights in the osteoblastic differentiation of marine natural products and possibility for their application in bone health supplement.

  • Allergic contact dermatitis (ACD) is an allergen-specific T-cell-mediated inflammatory response, albeit with unclear pathogenesis. Exosomes are nanoscale extracellular vesicles secreted by several cell types and widely distributed in various biological fluids. Exosomes affect the occurrence and development of ACD through immunoregulation among other ways. Nevertheless, the role of exosomes in ACD warrants further clarification. This review examines the progress of research into exosomes and their involvement in the pathogenesis, diagnosis, and treatment of ACD and provides ideas for exploring new diagnostic and treatment methods for this disease.

  • 본 연구에서는 새로운 개념의 항균처리 기술을 도입하여 항균 물질을 플라스틱 용기에 혼입하지 않고도 항균기능이 발휘되도록 하는 기술을 개발하고자 하였다. 기술의 요체는 항균기능정보를 물에 각인한 다음에 이를 플라스틱 제조용 원료 수지에 전사하여 최종 제품에서도 같은 기능이 나타나도록 한 것이다. 이러한 개념에 입각한 기능 정보 각인 기술의 실용화 가능성을 검토하기 위하여 시제품을 만들어 항균 실험을 수행한 결과 세균 증식 억제율이 75% 전후의 수준인 것으로 나타났다. 앞으로 이러한 기술이 보다 더 다듬어지고 그 작용기전이 밝혀진다면 더욱 뛰어난 제품이 개발될 가능성이 높다고 하겠다.

  • Lactic acid bacteria (LAB) are used as fermentation starters in vegetable and dairy products and influence the pH and flavors of foods. For many centuries, LAB have been used to manufacture fermented foods; therefore, they are generally regarded as safe. LAB produce various substances, such as lactic acid, ${\beta}$-glucosidase, and ${\beta}$-galactosidase, making them useful as fermentation starters. Existing functional substances have been assessed as fermentation substrates for better component bioavailability or other functions. Representative materials that were bioconverted using LAB have been reported and include minor ginsenosides, ${\gamma}$-aminobutyric acid, equol, aglycones, bioactive isoflavones, genistein, and daidzein, among others. Fermentation mainly involves polyphenol and polysaccharide substrates and is conducted using bacterial strains such as Streptococcus thermophilus, Lactobacillus plantarum, and Bifidobacterium sp. In this review, we summarize recent studies of bioconversion using LAB and discuss future directions for this field.

  • Antibiotics supplementation in animal feeds results in bacterial resistance to the antibiotics and residue of the antibiotics in animal products, which can cause serious problems in human health. Therefore, the finding of new substances replacing antibiotics are needed. New substances are egg york antibody, probiotics, organic acid, mannanoligosaccharide(MOS), fructooligosaccharide(FOS), and chitosan etc. Egg york antibody is antibody to obtain from egg york of the chicken injected the specific antigen. Probiotics can prevent the problems of residue of the antibiotics and resistance to the antibiotics. Organic acids ctrl preservation of colostrum inhibit the rottenness and increase the beneficial bacteria. MOS and FOS increase the beneficial bacteria, too. Chitosan is used the immune material to active the anti-bacteria.
