본 연구는 건강보조제 및 약제로서 전신의 염증반응 및 여러 약리적 효능을 가지고 있는 홍삼이 국소적인 안면 통증 의 완화에 영향을 끼치는지에 관해 조사하였다. 실험동물은 4그룹으로 대조군(n=6)과 5% 포르말린 주입군(n=6), 5% 포르말 린+D.W. 주입군, 홍삼(4.5 ml)(n=6) 복용군으로 나누어 45분간 안면을 긁거나 문지르는 행위를 계수하여 비교하였다. 홍삼 복용군에서 포르말린 주입군에 비해 유의하게 긁거나 문지르는 행위가 줄어들었으며, 15분부터 통증완화효과가 증가되기 시작되어 30분까지 유의한 효과를 보였다. 홍삼투여군에 대한 단백질정량분석 (western blot)으로 통증유발기전에 연관되는 염증과 항산화, NO생성에 관련된 신호전달 단백질 p38 MAPK와 iNOS, Nrf2를 뇌, 연수에서 활성정도를 비교한 결과 감소하 는 경향을 확인할 수 있었다. 이상의 결과들은 홍삼이 전신적 약리효과 뿐만 아니라 국소적인 염증, 통증완화에도 효능이 있음 나타낸다. The effects of korean red ginseng (KRG) extracts on orifacial pain control in terms of the systemic inflammatory response and pharmacological effects as health supplements were investigated. The experimental group were divided into three groups, the control group (n=6), formalin (5%, 50 ㎕) injection group (n=6), and formalin (5%, 50 ㎕) injection added KRG administrated group (4.5 ml/kg, n=6). The KRG administrated group prior to the formalin injection significantly attenuated the behavioral response compared to that of the control group. Pain reduction was suppressed mainly from 15 min to 30 min. The KRG administrated rats showed significantly reduced p38 MAPK, iNOS and Nrf2 expression in the brain and medulla oblongata according to Western blot analysis. These findings suggest that KRE may have a useful effect on orificial pain control functions by preventing the p38 MAPK pathway.

This research was conducted to investigate the impact of viewing scenery and walking in the urban forest onphysiological relaxation of humans. The experiment was conducted in Hanbat Arboretum located in Daejeon, and thecontrol experiment was conducted in front of Daejeon City Hall. The subjects that participated in the experimentcomprised 24 Korean male university students in their 20s (average age, 21.1±2.5 years), participated in the experimentas the subject, and these subjects were classified into three groups divided into three locations such as the pine forest inArboretum, the pond in Arboretum, and the city. The subjects sat down and viewed scenery for 10 min, and they thenwalked for 15 min. Further, physiological changes were measured using indicators such as heart rate variability (HRV),blood pressure, and pulse rate. As a result, when subjects viewed scenery and walked in the urban forest, a statisticallysignificant increase in the high frequency (HF) power of HRV and decrease in systolic pressure was observed comparedwith when subjects viewed scenery and walked in the city. Through this research, it was found that activities like viewingscenery or walking in Arboretum of the city are effective in increasing the physiological relaxation of the city residents.

Here, we show that radicicol, a fungal antibiotic, resulted in marked inhibition of inducible nitric oxide synthase (iNOS) transcription by the pancreatic beta cell line MIN6N8a in response to cytokine mixture (CM: TNF-${\alpha}$, IFN-${\gamma}$, and IL-$1{\beta}$). Treatment of MIN6N8a cells with radicicol inhibited CM-stimulated activation of NF-${\kappa}B$/Rel, which plays a critical role in iNOS transcription, in a dose-related manner. Nitrite production in the presence of PD98059, a specific inhibitor of the extracellular signal-regulated protein kinase-1 and 2 (ERK1/2) pathway, was dramatically diminished, suggesting that the ERK1/2 pathway is involved in CM-induced iNOS expression. In contrast, SB203580, a specific inhibitor of p38, had no effect on nitrite generation. Collectively, this series of experiments indicates that radicicol inhibits iNOS gene expression by blocking ERK1/2 signaling. Due to the critical role that NO release plays in mediating destruction of pancreatic beta cells, the inhibitory effects of radicicol on iNOS expression suggest that radicicol may represent a useful anti-diabetic activity.

Objectives : Community Screening Interview for Dementia (CSID) is a reliable screening instrument for dementia, irrespe-ctive of educational level and cultural differences among various populations. This study aimed to develop the Korean version of CSID (CSID-K) for screening of dementia in Korean community residing old people. Methods : Study sample consisted of a dementia patient group and three control groups (depression, education, no education), each of them was composed of 30 community residing elders. CSID-K was administered, and demographic characteristic, depression, and cognitive function were investigated. Results : Split half reliability (Guttmans'), internal consistency (Cronbach's α ), and inter-rater and test-retest (two weeks) reliabilities of the CSID-K were excellent. Scores on the CSID-K were significantly correlated with other measures for cognitive function, In addition, scores on the CSID-K were significantly different between the dementia patient group and three control groups. Conclusion : CSI-K was a reliable and valid instrument to screen dementia in Korean community residing old people, It could be used not only in community settings but also in clinical settings and for cross-cultural researches.

To investigate the clinical aspects of CHT in atopic dermatitis (AD) treatments, the effect of CHT in anti-oxidative and anti-inflammatory cytokines were tested. 100% or higher cell viability was observed in all tested groups from 25 to 200 ㎍/㎖using Raw 264.7 cells. CHT showed dose-dependent DPPH scavenging activity, with more than 90% scavenging activities at 800 ㎍/㎖concentrations. CHT showed dose-dependent suppression activity of ROS production, especially at 200 ㎍/㎖of 37.5%. CHT decreased NO production activity, with significant decrease of 33.2% at 200 ㎍/㎖. IL-6, MCP-1, TNF-α production rate were decreased by approximately 25% when Raw 264.7 cells were treated with LPS and with CHT of 200 ㎍/㎖. Also, IL-1β production rate was decreased by 25% at 100 ㎍/㎖. The results above indicate that CHT significantly reduces the effect of oxidative and inflammatory cytokines. The use of CHT in dermatitis can be widely suggested.

Background: Although cardiopulmonary resuscitation(CPR) is a very effective therapy in cardiac arrest, it is hard to prove the true effectiveness of CPR. Several studies about out-of-hospital and emergency department CPR exist, but only a few reports about in-hospital CPR are available. This study was designed to investigate in-hospital cardiac arrest, to analyze the result of CPR, and to evaluate the problems associated with in-hospital CPR. Methods: A clinical analysis of 71 cases of in-hospital CPR announcement from January 2000 to August 2000 was performed. The initial rhythm on cardiac arrest, return of spontaneous circulation(ROSC), and the survivals were analyzed in the case of the 46 true cardiac arrest patients. Results: During 8 months, there were 71 cases of in-hospital CPR announcement. Among them, there were 46 cases of true cardiac arrest and 25 cases of non-cardiac arrest. Of the 46 true cardiac-arrest cases, 27(58.7%) experienced ROSC, 15(32.6) survived for over 24 hours, and 7(15.2%) survived to be discharged. The initial rhythms on cardiac arrest were 30 cases(65.2%) of asystole, 14(30.4%) of PEA(pulseless electrical activity), and 2(4.3%) of ventricular fibrillation, with ROSC being 17 cases(56.7%), 9(64.3%) and 1(50.0%) cases and discharged survivors being 4 cases(13.3%), 3(21.4%) and 0(0.0%) cases, respectively. Conclusion: Extraordinarily high proportions of asystole and PEA were seen in the initial rhythm of cardiac arrest, and those were associated with high survival rates. Although further study is needed to evaluate the course leading to this high proportion of asystole and PEA, this result suggests that if the EMS system in the hospital is activated promptly and systematically, a better outcome will be achieved in case of cardiac arrest with asystole and PEA.

Objectives : This study aimed to investigate the prospective associations of premenstrual dysphoric disorder (PMDD) with quality of life, socio-occupational function and disability. Methods : 170 nurses were recruited 6om two general hospitals. Interviews were made at baseline and at four follow-up points (two mid follicular phases and two late luteal phases ofthe two consecutive menstrual cycles). The baseline evaluation Consis-ted of sociodemographic characteristics and menstmal history. PMDD was diagnosed by DSM-IV criteria after observation of the two menstrual cycles. The follow-up evaluations were consisted ofthe World Health Organization Quality of Life-Brief form, the Social and Occupational Functioning Assessment Scale, and the World Health Organization Disability Assessment Scale-II. Results : PMDD was detected 15 (8.8%) of 170 participants. The PMDD group showed significantly worse quality of life and socio-occupational functioning than the none-PMDD group particularly at the late luteal phases. No significant differences were found in sociodemographic characteristics and menstrual history between those with and without PMDD. Conclusion : PMDD was prospectively associated with worse quality of life and socio-occupational functioning in this study group.

연구목적 : 본 연구의 목적은 광주광역시의 도시 및 농촌 지역에 거주하는 노인에서 치매의 유병률과 위험인자를 조사하고자 하였다. 부가적으로 이 두 지역간에 치매의 유병률과 위험인자를 비교하고자 하였다. 방 법 : 광주광역시의 전형적인 도시와 농촌지역의 65세 이상의 노인(N=1,598)을 대상으로, 2단계의 역학연구를 수행하였다. 1차 선별 단계에서는 38명의 훈련된 연구보조원이 대상노인을 면담하여, 사회인구학적 특징을 조사하고 한국판 간이정신상태검사(Korean version of Mini-Mental State Examination ; MMSE-K)로 평가하였다. 2차 임상 진단 단계에서는 1차 단계에서 MMSE-K 점수가 24점 이하인 노인(N=431)을 대상으로, 전문연구팀의 임상적 평가를 통해 치매를 진단하고 원인질환별로 알쯔하이머병(Alzheimer's disease ; AD), 혈관성 치매(vascular dementia ; VaD) 및 기타 치매로 분류하였다. 대상노인에서 치매의 유병률을 측정한 후, 광주광역시 전체 노인의 연령보정 유병률을 산출하였다. 전체 대상에서 AD의 위험인자를 조사한 후, 도시와 농촌군으로 나누어 분석을 다시 시행하였다. 결 과 : 1차 및 2차 단계의 참가율은 각각 71.0%(N=1,134) 및 83.2%(N=410) 였다. 연구 참여 노인(N=1,134)에서 전체 치매, AD 및 VaD의 유병률은 최소 각각 9.7%, 5.2%, 1.8%였다. 광주광역시 전체 노인의 연령 보정 유병률은 각각 10.7%, 5.7%, 1.9%인 것으로 산출되었다. AD의 독립 위험인자는 고령, 여성, 무학이었다. 도시와 농촌에 따른 유병률의 차이는 파악되지 않았다. 그러나 AD의 위험인자는 지역에 따라 차이가 있었다. 도시 노인에게는 무학만이, 농촌 노인에게는 고령과 여성인 경우가 독립 위험인자였다. 결 론 : 광주광역시 노인에서 치매의 유병률은 높았고, 이는 국내 다른 지역에서 수행된 선행연구 결과와 유사하였다. 알쯔하이머형 치매의 위험인자는 도시와 농촌에 따라 다른 결과를 보였다. 본 연구 결과는 한국에서의 치매의 실태를 반영하며, 치매의 적절한 관리와 예방을 위해서는 지역성 특성이 고려되어야 함을 시사한다. Objectives : The purpose of this study was to investigate the prevalence rate and risk factors of dementia in an urban and a rural sample of older persons in the metropolitan Kwangju area, Republic of Korea. In addition, the prevalence rate and risk factors of dementia between the two samples were compared. Methods : A two-phase epidemiological study of residents aged 65 or over(N=1,598) was conducted in a highly developed, urban and a non-contiguous, poorly developed, rural area of metropolitan Kwangju. In the first(screening) phase, 38 trained research assistants collectively peformed in-home interviews for all participants. Detailed sociodemographic characteristics were gathered and the Korean version of Mini-Mental State Examination (MMSE-K) was administered. In the second (diagnosing) phase, diagnosis of dementia was established for those scoring 24 or less on the MMSE-K in the screening phase(N=431), and etiological types of dementia were classified to Alzheimer's disease(AD), vascular dementia(VaD) or miscellanous type by two teams of experts. Prevalence rate of dementia was determined in the participants, and age-standardized prevalence rate adjusted by age distribution in metropolitan Kwangju was estimated. For AD, the risk factors were investigated in all participants, and analyses were repeated for the urban and rural samples separately. Results : The participating rates in the first and second phases were 71.0%(N=1,134) and 83.2%(N=410), respectively. In the participants, the prevalence rates of dementia(all types), AD and VaD were 9.7%, 5.2% and 1.8%, respectively. The age-standardized prevalence rates were 10.7%, 5.7% and 1.9%, respectively. Aging, female gender and no education(complete lack of formal education) were identified as independent risk factors for AD. No difference between the urban and rural samples was observed in the prevalence rates of dementia(all types), AD and YaD. However, risk factors for AD differed between these areas. In the urban sample, no education was the only significant factor ; whereas, aging and female gender were identified as risk factors in the rural sample. Conclusion : A high prevalence rate of dementia was observed among old persons in metropolitan Kwangju, consistent with previous studies conducted in other Korean areas. The risk factor profi1es for AD differed between urban and rural settings. The results of this study reflect the current status of dementia in Korea and suggests that appropriate management and prevention strategies for dementia should be tailored toward the geographic settings.
