본 연구에서는 한방이화주의 피부 생리기능 활성을 알아보기 위해 70% EtOH 추출물의 피부 미백, 주름 개선 및 항염증 효과를 조사하였다. HEE은 tyrosinase 활성 억제 및 tyrosine을 기질로 melanin이 형성되는 pathway에 관여하는 주요한 인자인 TRP-1과 TRP-2를 저해하는 작용 기전을 통해 피부 색소침착의 주요 원인 물질인 melanin 생합성을 농도 의존적으로 저해하는 것을 확인하였다. HEE은 피부진피 내 피부 탄력을 유지하는 elastin을 분해하는 효소인 elastase의 활성을 저해하였고, 피부의 keratinocyte가 생성분비하는 MMP-2와 MMP-9의 단백질 발현과 proteolytic 활성을 억제하여 노화에 따른 피부 주름 생성 억제할 수 있는 가능성을 확인하였다. 또한 세포 독성 없이 LPS에 의해 유도된 염증 반응을 50% 저해하는 HEE의 농도(IC50)는 24.9 μg/mL이며, 50 μg/mL 농도로 처리하였을 때 염증 반응 저해 효과가 70%로 높은 효과를 가지는 것을 확인하였다. 이상의 결과를 종합하면 HEE의 피부 미백, 주름 개선 및 항염증에 우수한 효과를 나타내고 있으므로 기능성 화장품의 주요한 소재로 이용 가치가 높을 것으로 사료된다. Extrinsic skin aging is characterized by the loss of skin tone and resilience, irregular pigmentation, and deep wrinkles. The aim of this study was to investigate the effects of Ehwa Makgeolli containing oriental herbs (Glycyrrhiza uralensis Fisch., Lycium chinense MILL., Morus alba L., and Saururus chinensis Baill) on skin whitening and wrinkling in human skin cells. We prepared Makgeolli extracts (HEE) with 70% ethanol. HEE significantly inhibited in vitro mushroom tyrosinase activity and reduced the cellular and secreted melanin content of mouse melanoma melanocytes (B16F1 cells). HEE down-regulated the protein expression of tyrosinase related protein (TRP)-1/-2, a key player in melanogenesis. Treatment with HEE in human keratinoctyes (HaCaT cells) inhibited the proteolytic activities of matrix metalloproteinase (MMP)-2/-9 in a dose-dependent manner and dramatically reduced the expression of MMP-2/-9. In addition, HEE attenuated lipopolysaccharide (LPS)- induced nitric oxide production in murine macrophages (RAW264.7 cells). These results indicate that HEE may be a great cosmeceutical ingredient for its whitening, anti-wrinkle, and anti-inflammatory effects.

Background and objective: This study was conducted to determine the preferences in flower jewelry by conducting a surveyusing conjoint analysis on the perception of flower jewelry and provide basic data for development of flower jewelryproducts. Methods: For the conjoint analysis, four attributes of flower jewelry were selected. Attribute 1 was related to the mainmaterial of flower jewelry, presented in three levels: cut flowers, potted flowers, and processed flowers. Attribute 2 wasrelated to wearing area presented in five levels of wearing area: hair, neck, ear, arm (wrist) and chest (shoulder). Attribute3 was related to price provided for selling products in flower shops, presented in three levels: less than 30,000 won,50,000-70,000 won, and more than 100,000 won. Attribute 4 was related to flower jewelry wearing time, presented inthree levels: less than 6 hours, 12-24 hours, and more than 24 hours. After extracting 25 profiles through orthogonaldesign, a questionnaire survey was conducted on 402 general participants, from which the responses of 343 participantswere analyzed. Results: By attribute of flower jewelry, the respondents attached most importance to price (34.14%), followed by wearingarea (29.18%), wearing time (18.51%), and material (18.17%), proving that the general public attached most importanceto price (Pearson's R = .987, p = .000). The preference in levels by attribute was highest for processed flowers in material,less than 30,000 won in price, hair in wearing area, and 12-24 hours in wearing time. Conclusion: By making flower jewelry based on the results of the analysis, it would be possible to help increase items soldin flower shops as well as their income.

Objectives : The aim of this study was to examine the behavioral and emotional problems associated with nocturnal enuresis in Korean children. Methods : Three hundred eighteen children with nocturnal enuresis, together with their parents, completed the Child Behavior Checklist (CBCL), Disruptive Behavior Disorder Scale according to DSM-IV (DBDS), Children's Depression Inventory (CDI), State-Trait Anxiety Inventory for Children (STAIC), and Piers-Harris Children's Self-Concept Scale (PHCSC). Ninety-three normal students were selected as the control group. Results : Compared to the normal control group, the mean scores with regard to the withdrawn, social problems, attention problems, delinquent behavior, aggressive behavior, externalizing problems and total problems profiles were significantly higher in the nocturnal enuresis group according to the CBCL results. The nocturnal enuresis group also scored significantly higher in the ADHD and ODD profiles of the DBDS. The nocturnal enuresis group was more depressed and anxious than the control group according to the results of the CDI and STAI. The mean score of the PHCSC was significantly lower in the nocturnal enuresis group when compared to the normal control group. Conclusion : The results of this study suggest that children with nocturnal enuresis in Korea have clinically relevant behavioral and emotional problems. The findings support the link between nocturnal enuresis and psychopathology in Korean children.

Multiple bilobar liver matastases (MBLM) are the main cause of low resectability in the colon cancer liver metastases. The authors experienced one case of initially non-resectable colon cancer liver metastases. He was curatively and safely treated with a two-stage hepatectomy using the new method of future remnant liver volume growing. A 54-year-old man was referred to our department with the sigmoid colon cancer combined with MBLM, which were checked in two small metastatic lesions in the left lobe and five large sized lesions in the right lobe in the computed tomogram (CT). A laparoscopic assisted anterior resection was primarily performed. We performed the 1^(st) stage hepatectomy 3 weeks after the colon resection. Intra-operative Ultrasonogram (US) found 9 small superficial metastatic lesions in the left lobe. All that lesions were completely removed by non-anatomical wedge resection. An occlusion ballon catheter was placed in the right portal vein through a small branch of the inferior mesenteric vein at that time. The future remnant liver volume was sufficiently increased 3 weeks after the 1^(st) hepatectomy. A right hepatectomy was safely performed 22 days after the 1^(st) hepatectomy. The patient received a regional chemotherapy (interleukin2 based immuno-chemotherapy through hepatic artery) for 4 months, then received 9 cycles of systemic chemotherapy (biweekly Oxaliplation, leucovorin, plus 5-fluorouracil) without any recurrence evidence.

脾胃의 氣機升降의 生理·病理·治法에 대한 考察 및 臨床例

元泰喜,文九,文錫哉 한국전통의학연구소 1997 한국전통의학지 Vol.7 No.2

氣의 升降은 생체에서지의 가장 중요한 형태이다. 협의의 의미로 氣의 升降운동은 脾胃의 升降운동으로 요약할 수 있다. 그러므로 脾胃의 升降은 氣의 생리적인 운동에 있어서 매우 중요하다. 臟腑의 치료효과를 제고하기 위해서 본 눈문은 臟腑의 생리, 병리, 치료면에 있어서 氣의 升降의 중요성을 연구하였다. 다음과 같은 결론을 얻었다. 1. 脾胃의 생리는 脾主升과 脾主降이다. 2. 臟腑의 생리와 병리는 脾胃의 升降과 관련된 五臟六腑의 氣機와 관련되어 있다. 3. 脾胃의 병리상태는 升淸降濁의 정상적인 생리가 이루어지지 않는 상태이다. 4. 병리적인 脾胃의 升降은 升降太過, 升降不及, 升降反作으로 분류할 수 있다. 5. 脾胃病의 치료관건은 氣의 升降을 조절하는 것이다. 6. 脾胃升降失調의 치료는 氣의 升降을 조절하여 和胃柔肝시키는 치법 등을 사용하여 원인과 증상에 따라 치료한다. The function of ki (氣) is ascending and descending (升降) , which is the fundamental formality of the vital energy. If we interpret it in a narrow sense, the ascending and descending (升降) of ki (氣) is that of Biwi (脾胃). Therefore the ascending and descending(升降) of Biwi (脾胃) is very important in physiological function of ki (氣). For increasing the efficiency about the treatment of Jang Bu (臟腑 internal organs), this study was to investigate the importance of the ascending and descending (升降) of ki (氣) on the physiology, pathology and treatment of Jang Bu (臟腑 internal organs). The condusion could be summarized as follows: 1. The physiology of Biwi (脾胃) is that Bi (脾) sends clarity (food essence) upward and Wi (胃) sends disested food downward. 2. The physiology and pathology of Jang Bu (1lJlJ1f internal organs) is associated with the ascending and descending (升降) of Biwi (脾胃) and the vital function of Jang Bu (臟腑 internal organs) has casual relation with the ascending and descending (升降) of Biwi (脾胃). 3. The pathology of Biwi (脾胃) is the disturbance of the ascending clarity (升淸) and descending turbidity (降濁). 4. The pathological ascending and descending (升降) of Biwi (脾胃) is classified into the excess, deficiency and reaction of the ascending and descending. 5. The point of treatment Biwi (脾胃) disease is the regulation of the ascending and descending (升降) of ki(氣). 6. The method of treatment about the disturbance of the ascending and descending (升降) of Biwi (脾胃) is to replenish and elevate ki (氣), check upward perverted flow ki (氣) and regulate Wi (胃), soothe Gan (肝) and regulate Wi (胃) etc. according to the cause and symptom.

It is important to interpret the soil chemical properties in order to effectively manage the farmland. This study was conducted to investigate the soil chemical properties of upland soybean field according to the soil series at 32 upland fields located in the parts of Gangwon-do. Soil sampling sites were selected by using the National Statistics DB and KSIS DB that is a soil environment information system provided by the Rural Development Administration. Soil samples were collected from 0~15 cm of top soil before seeding or transplanting, air-dried, passed through a 2 mm sieve, and analyzed for soil pH, EC, organic matter, available phosphorus (P2O5), exchangeable potassium, exchangeable calcium and exchangeable magnesium. The average chemical properties have exceeded the each nutrient optimum range level of RDA, except the organic matter in experimental soil 2015. And despite application of conventional fertilization, each soil series nutrient contents were change respectively. The results of this study suggest that conventional fertilization should be applied based on the analysis about the amount of accumulated nutrient contents in the soil.
