Objective: To compare COH characteristics and IVF outcomes among IVF-ET patients who were treated with various therapeutic modalities for ovarian endometriomas and to propose effective pre-cyclic therapeutic modalities to improve IVF-ET outcomes in the patients with ovarian endometriomas. Methods: All cases that had undergone IVF-ET after laparoscopy between January 1997 to August 2003 were reviewed. Forty-eight patients with tubal factor were assigned to Group I. Twenty seven, 22 and 38 patients diagnosed as severe pelvic adhesion with ovarian endometriomas by laparoscopy received only medical therapy (Group II), cyst aspiration (Group III), and sclerotherapy (Group IV), respectively. Laparoscopic cystectomy was performed in 20 patients (Group V). Resistance index was measured on day administering hCG. Results: As compared with Group I, in Group II resistance index increased (p<0.05) but number of oocytes, good-quality oocyte ratio (mature and intermediate oocytes/total retrieval oocytes), fertilization rate, and embryo development rate decreased (p<0.05). In Group III fertilization rate and embryo development rate decreased (p<0.05). There was no difference between Group IV and Group I in all parameters except basal FSH which increased (p<0.05). In Group V basal FSH, and resistance increased (p<0.05) and number of oocytes and good-quality oocytes ratio decreased (p<0.05). Conclusion: Sclerotherapy is an effective therapeutic option which can be done prior to IVF-ET cycles in the patients with ovarian endometriomas. Further studies on a large scale are necessary to confirm these data.

Objective : This study seeks to define the expression of epidermal growth factor(EGF) and transforming growth factor(TGF)-α and epidermal growth factor receptor(EGFR), and the relationship to the tumor progression of human cervical epithelial neoplasia. Methods : To confirm the expression of EGF, TGF-α and EGFR immunohistochemically in normal cervix, cervical intraepithelial neoplasms and cervical carcinomas, we used monoclonal antibodies to EGF, TGF-α and EGFR. Results : Immunohistochemical stainings using anti-EGF, anti-TGF-α and anti-EGFR antibodies showed weak or moderate stainings in all cases. Normal and CIN cases showed predominantly basal and parabasal expression of EGF, TGF-α and EGFR, and its expression decreased as the cells became increasingly differentiated toward the surface of the epithelium. In the cervical carcinoma EGF and TGF-α expressed weakly to moderately focally, and EGFR expressed intensely in all malignant cells. Conclusion : These results suggest that EGF, TGF-α and EGFR may involved in cellular proliferation of cervical squamous epithelium and have a significant role in the progression of cervical cancer.

The purpose of this study is to find out the historical background of people``s negative perceptions on and attitudes to the persons with mental disorder in current Korean society, which perceive those persons as ``dangerous people who behave impulsively violent and aggressive`` and try to ``separate them from the local community`` by reviewing the changes of the environment surrounding them during Japanese Colonial period. For this purpose, I looked into the related movement at that times both in main land of Japan and its colony Chosun referring to ChosunChongdokbuKwanbo or the official gazette of Japanese Government-General of Korea, MaeilShinbo, ChosunIlbo, DongaIlbo and other Japanese publications. The study found that there was a procedure in which ``wandering`` persons with mental disorder were separated from the local community and confined to asylums by social hygienic perception and attitude of Japanese Imperialism under close cooperation between the colonial sanitary police and modern psychiatric system in the colony Chosun. In this procedure Japanese Imperialism gave image of ``dangerousness`` and ``impulsiveness`` to persons with mental disorder and it is inferred that it was due to the result of pursuing convenience to dominate Chosun as its colony. It is meaningful that this study deduced the historical background of perceptions and attitudes of separation and exclusion towards persons with mental disorder in current Korean society by reviewing organizing the series of incidents surrounding those people during Japanese Colonial period. However, it is not likely that such efforts of Japanese Imperialism would have directly affected perceptions and attitudes of people in Chosun at that times. While it is true that the policy and activities of Japanese Imperialism had much influence on Korean society due to the unique historical circumstance or the Colonial period, there could be a collision between the policy of Japanese Imperialism and the traditional custom of Chosun which had been inherited from the past. And in terms of medical sector, the activities of missionaries from western countries also have left significant marks after the ``OpenPort``ofChosun. Accordingly, the changes of people``s perception in the colony Chosun on the person with mental disorder can be found out and deeply understanding of the people``s attitudes towards those people in Korea after the Independence can be achievable only in the inter-relationship among the 3 active parties above.

본 연구의 목적은 개화기(1876-1910)에 이루어졌던 의료복지활동의 양상을 살펴보고자 하는 것이다. 이를 위해 해당 시기를 연구한 선행 연구들을 중심으로 문헌고찰 하였다. 개화기의 시대적 상황과 공공 의료체제, 민간의 의료사업을 고찰하였고, 이들의 의료 복지 활동을 주체, 대상, 형태에 따라 탐색 및 정리하였다. 그 결과, 의료 복지 활동의 주체로는 크게 공공(조선 후기 정부, 대한제국 황실, 통감부)과 민간(선교사 단체, 한의사 단체) 주체가 두축이 되어 활동을 전개한 것으로 나타났다. 의료복지활동의 대상은 대부분 빈곤한 환자, 전염병자가 주를 이루었고 그 당시 사회적으로 소외된 계층이었던 여성, 고아를 포함한 어린이, 한센병자, 행려병자, 죄수, 무의무탁한 자, 군인, 그리고 농촌 지역주민들에 대한 복지활동이 펼쳐졌다. 활동의 형태는 주로 ``구료``, ``시료``로 표현되는 무료 진료, 무료 치료, 약제비무료 혹은 저가 치료와 순회 진료로 이루어졌다. 연구의 결과로 나타난 활동들은 그 시기에만 국한된 것이 아니라 현재까지 이어지는 하나의 연속선으로 볼 수 있었으며, 본 연구는 그와 같은 역사적 고리를 탐색하고 정리하였다는 것에서 의의를 가진다. 특히 현재 의료사 회복지의 역사에 관한 연구가 전무한 실정에서 본 연구의 결과는 추후 연구를 위한 초석을 마련했다는 점에서 함의가 클 것으로 사료된다. The aim of the research is to see how the medical welfare activities during the civilization age fared. To do this, we studied preceding researches with related documents. We studied on the situation of the age, public medical system, civil medical businesses and we broke down their activities into the subject, the object and the forms. As a result the public sector(later Chosun dynasty, the emperial Daehan Royalty, the Residence-General) and the civil(missionaries, the oriental medicine organizations) were shown to be thought of as two main bodies. The target of their activities were mostly poor patients, and poor patients with contagious diseases who were regarded as major body of patients and others include socially marginalized people who were women, children including orphants, people with Hansen``s disease, persons fallen sick on the road, criminals, people with no protector, soldiers, and people living in rural areas. The activities were practiced mainly as ``kuryo``, ``shiroy`` which mean free diagnosis, free treatment, free medication or low priced treatment and itinerant treatment. These activities were not confined to the mentioned age but have continued to the present arranged the historical link. Particularly given that there has been no research on the history of medical social welfare, this research is meaningful in that it laid the basis for further studies.

토양검정에 의한 유기자원 시비처방이 감자의 생육 및 양분이용효율에 미치는 영향

In this study, we verified the effects of organic amendment application based on soil testing in potato cultivation. The application rate of organic amendments was determined based on the inorganicization rate of nitrogen, phosphoric acid, and potassium in the organic amendments. There was no significant difference in the length, stalk number, stalk diameter, and leaf color of potato plants under organic amendment application compared with those under chemical fertilization. The quantity of potato tubers and yield of marketable tubers under organic amendment application were higher than those under chemical fertilization. The top fresh weight and top-to-root ratio were the highest under organic amendment application, followed by those under chemical fertilization and the control. The inorganic nitrogen content in the leaves and stems of potato plants was the highest under chemical fertilization. There was no difference in the phosphoric acid content between the potatoes under chemical fertilization and those under organic amendment application. The potassium content in potatoes was higher under chemical fertilization than that under organic amendment application. While the change trend of inorganic nitrogen content in the roots was similar to that in the leaves and stems, the potatoes under organic amendment application, with the highest yield, showed the highest dry weight. The tuber weight showed a positive correlation with plant length, stalk number, and stalk diameter. The higher the weight of the tuber, the higher the weight of the marketable tuber, and the higher the top fresh weight, the higher the yield. Therefore, to increase yield, it is necessary to supply nutrients to improve the top fresh weight to the optimal level. There was no difference in the utilization efficiency of nitrogen and potassium between the potatoes under chemical fertilization and those under organic amendment application. The utilization efficiency of phosphoric acid was increased by 0.1% in potatoes under organic amendment application compared with that under other treatments. Regarding soil chemistry after harvest, the soils under organic amendment application showed a higher electrical conductivity and higher nitrogen and phosphoric acid content than those under other treatments. Therefore, the organic amendment method used in this study can be an alternative to chemical fertilization. It is also advantageous for the cultivation of subsequent crops in potato fields.

Background : Several angiogenic factors such as bFGF and VEGF have been shown angiogenesis of placenta. PGE2 and PGI2 may be important in successful establishment of pregnancy. Objective : We studied to investigate whether PGE2 and PGI2 regulate expression of VEGF and bFGF gene in the cultured human trophoblast cells. Methods : Human trophoblasts were isolated from the placenta of early gestation (6-12 weeks). Isolated trophoblasts were cultured in the different concentration of PGE2 and PGI2 and according to the different cultured time of PGE2 and PGI2, respectively. Total RNA was extracted and RT-PCR was performed. Result : Expression of bFGF was increased in 10-7M and 10-6M of PGE2 and was always increased in the all different concentration of PGI2. Four isoforms (VEGF121, VEGF165, VEGF189, VEGF206) were always expressed in the all different PGE2 and PGI2 concentration compared to the control group. However, there was no significant difference in the all different PGE2 and PGI2 concentration. In both PGE2 and PGI2 treatment group, expression of bFGF was decreased at 60 min compared to the control group and was gradually increased in time-dependent pattern. At 180 min, its expression was similar to the control group. Conclusion : Our data suggest that the expression of bFGF gene is influenced by cultured time and concentration of PGE2 and PGI2, although the expression of VEGF gene is not influenced.
