황지숙,송경식,김양섭,석순자,이태호,유익동 한국미생물생명공학회 ( 구 한국산업미생물학회 ) 1996 한국미생물·생명공학회지 Vol.24 No.5

담자균류로부터 지질과산화 저해물질을 탐색하던 중 강원도 오대산 지역에 자생하는 버섯의 한 종류로 부터, Sparague-Dawley계 rat의 간 mirosome 분획의 지질과산화를 강하게 억제하는 물질이 있음을 발견하였다. 이 버섯의 미생물학적 특성을 관찰한 결과 민주름버섯목, 굴뚝버섯과에 속하는 까치버섯(Polyzellus multiplex)으로 동정하였으며 본 버섯의 자실체 methanol 추출물을 benzene, ethylacetate로 순차적으로 추출하고 각종 chromatography를 이용하여 활성물질을 정제한 결과, ethylacetate층으로 부터 황산화활성을 나타내는 PM1을 benzene층으로 부터 지방산 계열의 PM2와 PM3 화합물을 순수하게 분리 정제하였다. PM1은 정색반응 및 각종 기기분석 결과 thelephoric acid계의 화합물로 동정되었으며 PM2 및 PM3는 각각 linoleic acid와 oleic acid로 동정되었다. 지질과산화 활성물질로 분리정제한 PM1 화합물의 IC_50 값은 1.96 ppm이었으며 LD_50 값은 500 mg/Kg 이상이었다. In the course of screening lipid peroxidation inhibitor from basidiomycetes, a mushroom, which was collected at O-Dae mountain in Kangweon-Do, was found to have active compound. The mushroom was identified as Polyzellus multiplex, which belongs to Aphylloporalles Thelephoraceae, on the basis of macroscopic and microscopic characteristics of the fruiting body. The methanol extract of fruiting body was extracted with benzene and ethylacetate, sequentially. By using various kinds of chromatographies, PM1, and PM2 and PM3, were purified from the ethylacetate extract and the benzene extract, respectively. Color reaction and analyses of IR, UV, and NMR spectra indicated that PM1 was a derivative of thelephoric acid, and PM2 and PM3 were linoleic acid and oleic acid, respectively. IC_50 of PM1 for inhibition of lipid peroxidation was 1.96 ppm and LD_50 was 500 mg/kg.

2.9%의 과산화수소를 함유한 시험용 부착형 미백제(Medison dental whitening strip, Samsung medical Co.,Anyang,Korea)를 실험군 피험자 23명, 시험용 미백제에서 과산화수소를 제외한 동일한 제재를 대조약으로 대조군 피험자 24명에게 매일 1시간 30분씩, 2주간 적용하여 임상적 효능과 안전성을 평가하였다. 미백 효과는 Shade Vision, Chroma Mete 및 Vitapan classical shade guide를 이용하여 색변화를 측정하여 다음과 같은 결론을 얻었다. 1. 실험군에서의 전체 치아의 색변화량(ΔE^(*))은 세 가지 측정법에서 모두 대조군에 비해 통계적으로 유의한 차이를 보였고 (p < 0.05). 쉽게 인지할 수 있는 정도였다. 2. 색변화는 색좌표 상에서 명도의 증가와 녹색조 및 청색조로의 변화에 의해 얻어졌다. 3. 치아별로는 어두운 견치의 색변화량이 가장 컸고, 측절치, 중절치 순으로 감소하였다. 4. 47명의 피험자 중 5명이 경도의 과민증을 경험하였으나 곧 완화되었다, 치은염증지수와 전기치수검사 결과 시험 전후에 차이가 없어 안전성을 확인하였다. This study evaluated the effectiveness and safety of an experimental bleaching strip (Medison dental whitening strip, Samsung medical Co., Anyang, Korea) containing 2.9% hydrogen peroxide. Twenty-three volunteers used the bleaching strips for one and a half hour daily for 2 weeks. As control group, the same strips in which hydrogen peroxide was not included were used by 24 volunteers with the same protocol. The shade chang (ΔE^(*), color differnce) of twelve anterior teeth was measured using Shade Vision (X-Rite Inc., S. W. Grandville, MI, USA), Chroma Meter (Minota Co., Ltd. Osaka, Japan) and Vitapan classical shade guide (Vita Zahnfabrik, Germany). The shade change of overall teeth in the experimental group was significantly greater than that in the control group (p < 0.05) and was easily perceivable. The change resulted from the increase of lightness (CIE L^(*) value) and the decrease of redness (CIE a^(*) value) and yellowness (CIE b^(*) value). The shade change of individual tooth was greatest in canine, can smallest in central incisor. The safety of the bleaching strip was also confirmed. 〔J Kor Acad Cons Dent 31(4):269-281, 2006〕

This study was performed to identify risk factors for depression among the elderly in a rural area. A survey was done for the elderly living in Gosam-myenn, Ansung-kun during the period of July 28, 1997 and July 30, 1997. Demographic and sodoeconornic characteristics, and functional and health Status were assessed using a structured questionnaire, and the level of depression was measured by GDS score. The data obtained were analyzed by frequencies, percentage, t-test, ANOVA, and multiple regression, and the results were as follows: 1. The total sample consisted of 133 elderly. Of them, 47 elderly (35.4%) showed significant depressive Symptoms. 2. The GDS score was the highest for the group over 85 years of age (p < 0.05). Those living alone or widowed showed lower GDS score than those living with someone or married (p < 0.05). 3. The GDS score was the highest in the absolutely dependent group, followed by the partially dependent group, and the independent group (p < 0.01). The elderly who perceived their health Status as excellent showed the lowest GDS score. In contrast, those who had more than five chronic diseases showed the highest GDS score. 4. The elderly receiving financial and emotional support from their family or friends showed lower GDS score compared to those without any support. 5. The economically dependent group showed higher GDS score than that of independent group. 6. The elderly who involved in leisure activities showed lower GDS score than those without any involvement. 7. In terms of risk factors for depression, we found that perceived health Status, subjective economic Status, leisure activities, living arrangement and financial support were inversely associated with GDS score, whereas labor support was positively associated with GDS score. Based upon the above findings, this study suggests that these risk factors for depression in the elderly should be taken into consideration for a comprehensive mental health program for the elderly living in the rural area.

Purpose: This study researched the comparison of oral care methods between the wet gauze and the water gargling for nasal surgery patients. It executed to find out more effective method to relieve thirst. Method: We divided two groups; the wet gauze and the cold water garaling. We assessed patient's oral cavity state and sebjective oral dryness for three times; firstly before the intervention, secondly 15 minutes after 1st intervention and thirdly 15 minutes afrer 2nd intervention. Result: As the intervention, there was no difference on oral condition subhectvely, but there was a difference on thirsty reduction objectively. As the aral dryness has relieved through both methods. It showed the repeated gargling helps more to relieve oral dryness effectively than the wet gauge. At PACU, post nasal surgery patient's oral dryness was decreased with gauze more than two times, patient's oral dryness was relieved. Whereas the dryness was relieved after applying the cold water gargling for just one time. Conclusion: The water gargling is more effective intervention than the wet gauze. Especially, oral dryness was improved in the section of objetive oral assessment index.

Purpose: Given the increased frequency of operative therapy and radiation therapy on breast cancers and uterine cancers, there is very little information on lymphedema associated with these treatments in Korea. Thus, the authors conducted this study to describe and analyze the data which they had obtained from the patients. Method: A retrospective study was undertaken on 840 patients who registered to the Lymphedema Clinic of Samsung Seoul Hospital throughout the period of February 1995 to August 2001. Result: Out of 840 patients, 205 patients (24%) were confirmed as having primary lymphedema, while 635 patients (76%) had secondary lymphedema. The ratio of male to female for primary lymphedema was 1 :1.8(Male : Female), while secondary lymphedema demonstrated to be 1:21 (Male : Female), demonstrating a female preponderance. Secondary lymphedema mostly developed after undergoing treatment for uterine cancer (341 patients, 53.7%) and breast cancer (226 patients, 35.5%) The lesions of occurrence for both primary and secondary lymphedema were mainly in the lower extremities than the upper extremities. In regards to the degree of clinical edema, a large number of the patients, that is 633 patients (76%) had progressed to Stage Ⅱ~Ⅲ. Among the patients who developed edema after undergoing treatment for cancers, only 43 patients (7%) were provided information on the possibility of developing lymphedema, while the majority of the patients had no knowledge about this possibility. When the patients' subjective experiences were investigated on the degree of the edema, there was no significant increase in pain despite an increase in the degree of the edema (P<0.05), nevertheless, a significant increase was found in cosmetic problems (P>0.05). Conclusion: As a general rule, complete recovery from chronic lymphedema is not expected. However, early detection of lymphedema and timely appropriate treatment as well as aggressive patient education on lymphedema and its related complications can prevent its progression.
