Kyung Ok Jung(鄭卿玉),Don Koo Lee(李敦求) 한국육종학회 1986 한국육종학회지 Vol.18 No.4

This study was conducted to compare phenolic constituents in leaves and stem barks of Alnus hirsuta Alnus hirsuta(sex inversed), Alnus hirsuta var. sibirica, Alnus japonica, Alnus borealis, and Alnus maximowicz growing widely in Korea. The above alders were clustered using the Euclidean distance based on the phenolic composition. Eight phenolic compounds were identified in the leaves, while nine phenolic compounds in the stems. Phenolic constituents in leaves were not exactly same as those in stems. Total amount of phenolic compounds was higher in stems than in leaves. Thus, phenolic constituents differed not only among alder species but between organs.

The purpose of this study lies in clarifying the grammatical function of Korean particles ‘kkeseo, eseo, seo(께서, 에서, 서)’ and establishing their grammatical position. In addition to their features discovered in a number of discussions, it is claimed that through the analysis of their syntactic structure and passive sentences, ‘kkeseo, eseo, seo(께서, 에서, 서)’ are revealed to play a role of the subjects of noun phrase. However, ‘kkeseo, eseo, seo(께서, 에서, 서)’ are defined as auxiliary particles rather than nominative particles.

위지향(Ji-Hyang Wee),정현정(Hyun Jung Jung),정경옥(Kyung Ok Jung),성혜미(Hea Mi Sung),신유림(Yu-Rim Shin),박주현(Ju-Hyun Park),서현영(Hyeon-Young Seo),임정민(Jung-Min Lim),채한정(Han-Jeong Chae),이기웅(Ki Yung Lee) 한국식품영양과학회 2015 한국식품영양과학회지 Vol.44 No.4

본 연구는 난소 적출 동물 모델을 이용하여 고흥산 석류 농축액 시험군과 함께 이란산 석류 농축액을 주성분으로 하는 시판 제품의 혈청 생화학적 지표, 골밀도 등 몇 가지 지표를 분석하여 갱년기 증상 개선 효과를 비교하였다. 고흥산 석류 농축액과 시판 제품은 난소 절제 동물 모델의 골밀도(bone mineral density, BMD) 및 percent bone volume(bone volume/tissue volume), bone surface density(bone surface/tissue volume)를 증가시켰으며, 특히 고용량의 고흥산 석류 농축액(PE3)은 통계적으로 유의하게 골밀도 및 골볼륨을 증가시켰다. 시판 제품을 투여한 군도 골밀도를 증가시키는 양상을 보였으나 통계적 유의성은 없어 고흥산 석류 농축액이 이란산 석류 제품보다 골밀도 등 뼈 건강에 관련한 갱년기 증상 개선에 더 효과적이라고 사료된다. 고흥산 석류 농축액은 난소 절제에 의한 체중 증가 및 복부/내장지방 축적을 개선하였으며, 농도 의존적으로 HDL-C(high density lipoprotein cholesterol)는 증가시키고 low density lipoprotein cholesterol은 감소시켰다. 또한 고농도 석류 농축액(PE3)의 HDL-C/total cholesterol이 통계적으로 유의하게 증가하여 고흥산 석류 농축액이 갱년기 여성의 비만 및 혈중지질을 개선할 수 있을 것으로 기대된다. 불안장애 실험에서는 고흥산 석류 농축액 투여로 인해 불안장애가 개선되는 경향을 보였으나 통계적 유의성이 없었고, 이란산 시판제품 투여 시에는 대조군에 비해 유의하게 개선시키는 것으로 나타났다. 우울증 또한 시판 제품 투여군에서는 대조군에 비해 유의하게 개선 효과를 나타내었으나 고흥산 석류 농축액 투여군에서는 우울증 개선 효과가 확인되지 않았다. 이상과 같은 결과를 통해 고흥산 석류 농축액은 난소를 적출한 rat의 골 소실을 현저히 개선하고 복부/내장지방 및 혈중지질을 농도 의존적으로 개선하여 골다공증, 비만 및 심혈관 질환과 같은 갱년기 증상에 효과가 있음을 확인하였다. 그러나 고흥산 석류 농축액 투여군에서 대표적인 갱년기 증상인 우울증과 불안장애 개선에 유의성 있는 효과가 나타나지 않는 것은 동물실험 모델에서 사람에게 나타나는 다양한 갱년기 증상을 모두 평가하기에 한계가 있는 바, 향후 추가적인 연구를 통해 고흥산 석류 농축액이 갱년기 여성에게 나타나는 여러 가지 증상 중 특정 증상에 대해 선택적으로 효과를 나타내는지에 대해 임상시험을 통해 검증할 필요가 있겠다. In this study, the effect of Goheung pomegranate extract on postmenopausal syndrome was evaluated both in vitro and in vivo in ovariectomized Sprague-Dawly (SD) rats. Sixty female SD rats were divided into six groups: sham, sham operation and distilled water; OVX, ovariectomized and distilled water; PE1, ovariectomized and pomegranate concentrate (0.75 mL/twice/d); PE2, ovariectomized and pomegranate concentrate (1.5 mL/twice/d); PE3, ovariectomized and pomegranate concentrate (2.2 mL/twice/d); and CE, ovariectomized and commercial pomegranate concentrate (2.2 mL/twice/d). Percent bone volume (bone volume/tissue volume) and trabecular thickness (Tb.Th) improved in a dose-independent manner in PE1, 2, and 3. Especially, bone mineral density was significantly improved in PE3 (P<0.05) compared to OVX. Pomegranate extract reduced body weight and visceral fat mass. High density lipoprotein cholesterol (HDL-C) level slightly increased in a dose-independent manner in the experimental group. In addition, HDL-C/total cholesterol level of PE3 significantly increased (P<0.05) compared with OVX. These results show that pomegranate concentrate improved blood lipid levels and bone metabolism in ovariectomized rats. Therefore, Goheung pomegranate concentrates are expected to improve cardiovascular and bone-related diseases in menopausal women.

본 연구는 녹차씨 압착박의 활용성을 증가해 보고자 녹차씨를 압착한 후 남은 박을 추출하여 총 페놀, 조사포닌, 카테킨, 나린게닌 함량을 확인하고 3T3-L1 세포에서의 지방세포분화 억제 관련 효과를 확인하였다. 또한 기존에 체지방 감소 효능이 있는 것으로 알려진 녹차와도 비교하였다. 녹차씨 압착박 추출물과 녹차추출물의 페놀, 조사포닌, 카테킨, 나린게닌 함량을 비교한 결과 녹차씨 압착박 추출물에서 나린게닌 함량이 높음을 알 수 있었다. 3T3-L1 세포에서 Oil Red O 염색법을 이용한 지방 축적저해 정도 및 세포내 중성지방 함량을 측정한 결과, 녹차씨 압착박 추출물에서 지방 축적저해 및 중성지방의 함량이 감소하는 것을 확인하였다. 녹차씨 압착박이 지방합성 및 에너지 조절 효소에 미치는 영향을 알아보기 위해 단백질 발현 실험을 실시한 결과, 녹차 또는 녹차씨 압착박 추출물에 의해서 AMPK 및 ACC의 인산화 증가 및 FAS의 발현이 감소하는 것을 확인 할 수 있었으며, 이러한 효능은 녹차 추출물보다 녹차씨 압착박 추출물에서 더 강하게 나타나는 것을 알 수 있었다. 이상의 결과로부터 녹차씨 압착박 추출물이 녹차 추출물 보다 지방세포분화 억제 효과가 높게 나타나는 것이 확인되어져, 녹차씨는 추후 체지방 감소 효능을 갖는 식품 소재로도 활용이 가능 할 것으로 생각되어진다. The effect of the hot water extract of defatted green tea seed cake (GTSE) on lipid metabolism and the underlying mechanisms of lipolysis in mature 3T3-L1 adipocytes were investigated. In this study, we found that the naringenin content of GTSE was 5.5 ㎎/g; however, catechins were not detected. The intracellular lipid droplets were stained with Oil Red O dye and quantified. Compared to the control, lipid accumulation was significantly decreased by 52%, and intracellular triglyceride (TG) level was reduced by 33% after treatment with GTSE at a concentration of 40 ㎍/mL. To determine the mechanism of reduction in TG content, we determined the level of fatty acid synthase (FAS), phosphorylation of adenosine monophosphate-activated protein kinase (AMPK), and acetyl-coenzyme A carboxylase (ACC) in the cell model. Incubation of the 3T3-L1 adipocytes with GTSE stimulated AMPK and ACC phosphorylation in a dosedependent manner, and decreased the expression of FAS.

Asthma is the most prevalent chronic chilodhood illness. Asthma is a variable disease that parents and patients must of necessity make key observations and exercise considerable judgment. They must be educated and trained to take appropriate under a wide variety of circumstances. Parents and children need to be taught that well-child visits to a primary care provider and attention to optimal health habits increases the likelihood of remaining well and detecting and adverse problems early. A second important is that prevention of episodes is the best approach to controlling asthma. Thirdly, educating families on the principles of daily management is absolutely necessary. Action in theses three areas minimizes the effect of chronic illness and allow for fewer stressors to interfere with normal growth & development and a healthy lifestyle. Pediatric home care is rapidely growing area in home health agencies across the United States. The fundamental goal of planning and implementing the specific pediatric home care program should be to allow acutely and chronically ill children to remain in the most comforting and nurturing environment possible. Programs that combine quality patient-family care while decreasing health care costs can be initiated from this general model.
