      • 전립선 기질세포의 증식과 COX-2 발현에 대한 프로게스테론의 영향

        정수련,김성한,최이화,박지은,전은미,강영진,이광윤,최형철 영남대학교 의과대학 2006 Yeungnam University Journal of Medicine Vol.23 No.1

        전립선비대증은 노인 남성에서 흔히 유발되는 질환이며, 노화가 진행될 수록 빈도가 높아지는 특징을 가진다. 이 질환의 원인은 전립선기질세표의 과도한 증식으로 유발된다고 알려져 있지만 그 자세한 기전에 대해서는 잘 알려져 있지 않다. 전립선비대증에서 progesterone 수용체 양성 세포가 다른 전립선 종양에 비해서 많고, progesterone은 testosterone에서 DHT로 전환되는 것을 감소시키는 역할을 가진다고 알려졋다. 또한 남성 전립선 평활근의 과증식에 의한 질환이므로 평활근 세포의 증식과 관련성이 있다고 보고된 COX-2의 전립선비대증에 대한 영향에 대한 연구가 필요하다. 전립선 기질세포에 progesterone을 3일간 투여하여 배양한 경우 기질세포 증식은 차이가 없었다. Progesterone을 단독 또는 DHT와 같이 투여한 기질세포에서 남성호르몬 수용체 mRNA 발현은 비처리군과 비교하여 유의한 차이가 없었다. 또한 progesterone과 DHT 동시 투여에 의한 COX-2 mRNA 발현에도 차이가 없었다. 그러나 progesterone에 의한 남성 호르몬 수용체와 COX-2 단백 발현에서는 대조군과 비교하여 유의하게 감소시켰다. 이상의 결과는 progesterone은 남성호르몬 수용체에 대해 전사 후 반응 (post-transcriptional response)에 효과를 나타내어 남성호르몬 수용체 발현을 감소시키는 작용은 가지며, COX-2 발현 억제효과를 나타내므로 전립선비대증의 치료에 이용될 수 있을 것으로 사료된다. Background: Benign prostatic hyperplasia (BPH) is the most common benign tumor in older men; the etiology of this disease remains poorly understood. Testosterone and dihydrotestosterone (DHT) both act as androgen via a single androgen receptor. Testosterone is converted to DHT by 5α-reductase in prostatic stromal cells. Progesterone has been reported to inhibit DHT conversion; howevwe, its effect on prostatic stromal cells remains to be elucidated. Materials and Methods: In this experiment, we investigated the effect of progesterone on androgen receptor expression induced by DHT. We also tested the effect of progesterone on cyclooxygenase-2 (COX-2) expression, as well as prostate stromal cell proliferation using the cell count kit-8. Results: Progesterone did not cause an increase of prostate stromal cell proliferation. The mRNA expression of the androgen receptor and COX-2 were not changed by progesterone; the expressions of androgen receptor and COX-2 proteins were decreased by progesterone in prostate stromal cells. Conclusion: These results suggest that in prostate stromal cells, progesterone decreases androgen receptor protein expression, which results in decrement of COX-2 protein expression. This effect might be mediated by post-transcriptional regulation.

        People are getting more interested in their “quality of life” as they achieved certain level of economic development. Governments pay great attention on well-being and happiness of people as well and try to find the best way to improve citizens' quality of life. However, South Korea is still on 27th out of 39 OECD and G20 countries in quality of life index, which means that there are great needs to improve Koreans' quality of life. Moreover, it is expected that Korean women's quality of life might be worse than this in its patriarchal environments. In fact, there are few research regarding Korean women's quality of life and it is unknown what personal and social factors affect Korean women's quality of life and how we can improve it. This research attempts to find out factors related to Korean women's quality of life through the surveys of 536 Korean women. The results show that quality of life is most influenced by factors such as self-fulfillment, socio-economic independence, satisfaction with the residence, and satisfaction with cultural activities. In addition, happiness of Korean womem is greatly affected by various factors such as mental health, interpersonal relationship, self-respect, self-fulfillment, socio-economic independence, satisfaction with the residence, and satisfaction with cultural activities. Among various factors related to quality of life and happiness of Korean women, scores of self-respect, self-fulfillment, and interpersonal relationship are high, while scores regarding income are relatively low. Key words:Quality of Life, Happiness, Maslow

      • 청소년 문화축제참여가 자아정체성과 사회공존지수에 미치는 영향

        정명수,송은미,이강욱,정진영 朝鮮大學校 스포츠科學硏究所 2006 스포츠科學硏究 Vol.17 No.-

        This study aims to examine the influence of the participation in the festivals on the development of the self identity and the influence of the emotional outlooks based on the participation in the festivals and the emotional outlooks produced by the interaction with others on the development of the self identity with the young people who participated in the 2004 Yeosu International Youth Festival as the subjects. Putting these findings together, it is shown that the participation of the adolescents in cultural festivals has a positive influence on the development of their self-identity, and, in particular, it is also shown that the emotional outlooks produced by the participation in cultural festivals and the emotional outlooks obtained through the interaction with others have a positive influence on the self-identity of the adolescents. Accordingly, it is necessary to study those programs producing no oppositions and the methods of participation for the development of the self-identity of the adolescents, and it is also necessary to develop natural programs and incentives to smooth the complex and diverse interactions among the participants.

        Objectives : Pneumoconisis and noise-induced hearing loss (NIHL) have been reported as main occupational diseases by the Special Health Examination. The Industrial Accident Compensation Insurance has reported various work-related diseases, however, these two diseases occupied almost a half of compensated cases. Therefore, it was not well known about the status of occupational diseases other than pneumoconiosis, NIHL, and cardio-cerebrovascular accident (CVA). This study was conducted to analyze claimed cases as an occupational disease, that was requested to the Korea Industrial Safety and Health Agency (KOSHA). Methods : The local office of the Korea Labor Welfare Corporation (KLWC) has asked the KOSHA for confirmation of claimed cases as an occupational disease. We analyzed 379 cases requested from KLWC, the Ministry of Labor, employers, unions and occupational health agencies from 1992 to 1999. Results : Male was 80.7 % of the requested cases. Their mean age was 42 years old and 75.5 % of them were more than 35 years old. The requested cases were increased rapidly from 25 cases in 1992 to 108 cases in 1999 and the accept rate was 50.7 %. The majority of requested cases were respiratory diseases(22.4%), cancers(18.5%), Neuropsychiatric problems(14.5%), and musculoskeletal problems(13.5%). The accept rate was high in reproductive, respiratory, musculoskeletal and digestive disorders and low in neuropsychiatric, renal and otologic problems and occupational cancers. 73.6% of them were caused by chemical agents, especially 28.5 % were by organic solvents. 67% of them were clinically confirmed at university hospitals. A half of the cases were from KyongIn area, even the request came from the whole country. Conclusions : A claim was common in workers whose age was over 35 years old and exposure history was over 10 years. The respiratory diseases and neuropsychiatric disorders were still main problems in occupational health and occupational cancers was increasing even though its accept rate was not high yet.

        Background : There is increased recognition that rigorous approach to functional assessment will complement the assessment of clinical status. This study is to develop the appropriate visual function index in Korean patients with cataracts by the assessment of the reliability, validity of visual function indexes including VF-14. Methods : An prospective study was performed with 92 patients who had undergone either one eye or both eye cataract surgery by 3 ophthalmologists practicing at a university-hospital. Patients were interviewed, and clinical data were obtained. Doctors were questioned with self-entered questionnaire forms. Medical record was examined to understand surgery-process. The survey was conducted at 1-2 days before cataract surgery. Results : We used following measures : 7 visual function indexes, global measures of patients' trouble and satisfaction with vision, and best-corrected visual acuity (VA) in each eye. 7 visual function indexes showed a high internal consistency reliability (Cronbach's alpha coefficients ≥0.86). The better visual acuity(operated eye. better eye), the higher patient satisfaction with vision, the lower symptom score, the lower patient trouble with vision was correlated with preoperative visual function index scores. Among 7 indexes, VF-12 with the exclusion of 2 items drivings from VF-14 is a high Cronbach's alpha coefficient and correlation coefficient and the highest R². Conclusion : We conclude that VF-12 is reliable and valid in Korea. So we suggest that in Korea, all items of VF-14, the visual function index, which is in use internationally, ought to be surveyed and VF-12 which has been excluded by 2 items of drivings from VF-14 ought to beused for analysis.
