목적: 부인 종양에서 가장 심각한 문제중 하나인 난소암은 항암화학요법에 비교적 민감하게 반응하는 고형 종양이나 다양한 노력에도 불구하고 사망률은 큰 변화가 없는 실정이다. Cisplatin은 이들 항암제의 중심이며 가장 효과적인 약제이지만, Cisplatin에 대한 약제내성의 출현은 치료 실패의 중요한 원인이 되고 있고, 최근 Hereditary nonpolyposis colorectal cancer에서 입증된 DNA 부정합 보수 유전자의 변이가 여러 약제에 대하여 약제내성을 초래한다는 사실이 밝혀지고 있다. 이에 따라 Cisplatin 내성을 갖는 난소암 세포주에서 DNA 부정합 보수 유전자인 hMLH1과 hMSH2의 돌연변이와 Microsatellite instability 여부를 알아보고, 약제내성을 갖는 난소암 세포주에서 얻은 단일 세포의 clone들중 부정합 보수 유전자에 변이가 있는 clone과 정상인 clone을 분류하여, 이들에서 난소암의 2차 약제로 많이 쓰이는 Taxol, Topotecan의 항암제 민감도에 차이가 있는지 밝히고자 연구를 시행하였다. 연구방법: 상피성 난소암 세포주 2008과 이 세포주에 Cisplatin의 농도를 반복적으로 증가시켜 만들어진 2008/C13*5.25 세포주에서 추출한 cell clone으로 hMLH1과 hMSH2 단백질로 immunoblot을 시행하고 각각의 clone에 대하여 taxol 및 topotecan의 colony forming assay를 이용하여 항암제 민감도 검사를 시행하였다. 결과: 1. 2008 세포주와 2008/C13*5.25 세포주에서 hMLH1과 hMSH2에 대한 항체를 이용하여 immunoblot을 시행한 결과 각각의 세포주에서 모두 hMLH1과 hMSH2 단백질의 발현을 확인 할 수 있었다. 2. 2008 세포주에서 hMLH1(+)인 clone은 78개, hMLH1(-)인 clone은 22개 였고, 2008/C13*5.25 세포주에서는 hMLH1(+)인 clone은 73개, hMLH1(-)인 clone은 27개로, hMLH1(-)로의 변이는 2008/C13*5.25에서 약간 많았지만 통계적으로 유의한 차이는 없었다. 3. 2008과 2008/C13*5.25 세포주에서는 Taxol에 대한 민감도에 차이가 없었다. 그러나 2008/C13*5.25 hMLH1(-)의 clone들이 hMLH1(+)인 경우 보다 유의하게 Taxol에 민감하였고(P=0.049), 2008 hMLH1(+)인 clone들은 hMLH1(-) clone보다 유의하게 Taxol에 민감하였다(P=0.003). 4. 2008과 2008/C13*5.25 세포주에서는 Topotecan에 대한 민감도에 차이가 없었고. 2008/C13*5.25 hMLH1(-)의 clone들이 hMLH1(+)보다 유의하지는 않았지만 Topotecan에 약간 민감하였고, 2008 세포주에서는 hMLH1(-) clone들이 hMLH1(+)보다 유의하게 Topotecan에 민감하였다(P=0.001). 또한 2008과 2008/C13*5.25 두 세포주에서 hMLH1(-)인 clone들은 cisplatin 내성에 관계없이 유의하게 Topotecan에 민감하였다(P=0.001). 5. BAT25, BAT26, BAT34 primer에 대한 2008 hMLH1(+), hMLH1(-) clone과 2008/C13*5.25 hMLH1(+), hMLH1(-) clone의 microsatellite instability 결과는 모두 정상의 allele 소견으로 microsatellite instability를 나타내지 않았다. 결론: 이상의 연구 결과로 미루어 난소암에서 DNA 부정합 보수 유전자의 변이와 Cisplatin의 약제내성 사이에는 뚜렷한 관련이 없어 보이고, 난소암에서 hMLH1의 소실이 있는 경우는 오히려 Taxol이나 Topotecan에 민감한 것으로 나타났으며, 이러한 결과는 난소암 치료에서 1차 및 2차 약제의 선택에 도움을 줄 것으로 사료된다. Objective: Ovarian cancer represents a relatively chemosensitive solid tumor, with responsiveness to a range of agents. Cisplatin is the mainstay of drug treatment and is one of the most active single agent. However, the overall outcome for patients remains unsatisfactory and the emergence of drug resistance is a major factor in treatment failure. Loss of DNA mismatch repair is a common finding in many types of sporadic cancer as well as in patients with hereditary nonpolyposis colon cancer. Cells that lack DNA mismatch repair are resistant to commonly used chemotherapeutic agents. Selection of cells for resistance to cisplatin, a well-recognized mutagen, could result in mutation in genes involved in DNA mismatch repair. Methods: This study evaluated the mutation of hMLH1 and hMSH2, and its relation to the Taxol and Topotecan chemosensitivity in the clones from the ovarian cancer cell line 2008 and cisplatin-resistant cell line 2008/ C13*5.25. Results: 1. Cells from 2008 and 2008/C13*5.25 expressed both hMLH1 and hMSH2 when analysed with immunoblotting. 2. Twenty two out of 100 single-cell clones from 2008 and 27 of clones from 2008/C13*5.25 expressed no hMLH1. hMSH2 was expressed in all clones. 3. There was no difference of Taxol chemosensitivity between 2008 and 2008/C13*5.25 cell lines. In the 2008/C13*5.25 cell line, the hMLH1-deficient clones were more sensitive to Taxol than the hMLH1-proficient clones(P=0.049), but in 2008 cell lines hMLH1-proficient clones were more sesitive to Taxol(P=0.003). 4. There was no difference in Topotecan chemosensitivity between 2008 and 2008/C13*5.25 cell lines. In the 2008/C13*5.25 cell line, the hMLH1- deficient clones were not more sensitive to Topotecan than the hMLH1-proficient clones. In the 2008 cell lines hMLH1-deficient clones were more sesitive to Topotecan(P=0.001). Overall, hMLH1-deficient clones from both 2008 and 2008/C13*5.25 cell lines were significantly more sensitive to Topotecan(P=0.001). 5. Microsatellite instability was not demonstrated in all 4 types of single-cell clones from 2008 and 2008/C13*5.25 cell lines. Conclusions: The present results indicate that there is no relation between mutation of mismatch repair gene and cisplatin resistance. But hMLH1-deficient ovarian cancer cells are more sensitive to Taxol or Topotecan in this study. The latter finding mandates the examination to assess the mutation of hMLH1 in tumor cells before treatment or at the time clinical resistance to cisplatin develops in ovarian cancer.

This study aims to understand the reasons why the elderly become interested in and engage in dance as a leisure activity and give up the activity early. It will also explore methods that will attract and continually engage the elderly (60 and above) in dance classes for a long-term period. The participants of the study are all 60 years old and above who have voluntarily enrolled in dance classes. The dance classes are 50 minutes per class, twice a week. Most participants of this study drop out at the one years point. This study participants were selected using reputable case selective inductive category analysis which is widely used in the qualitative field of research. As such, the study is based on reputable case selection. The results are as follows: One reason that the elderly in the research chose to join a dance class was to enhance their health in their post 60’s while not being perceived as the “old generation” by the younger generations. A common excuse given to the younger generation for their participation is that they did not have the opportunity to engage in activities such as dance, at a young age and wanted to take advantage of their new found freedom. Another common reason given for participation in dance classes was the “fun factor.” The “fun factor” includes their interest in music in general, being able to participate in the dance activity with a partner, and the various genres of dance that they were exposed to. Finally, the research explored many reasons that the stress factors their class at the half way point. These reasons include the difficulty in learning musical terminology, the inability of the dance teacher to keep the participants’ interest, and the inability of the participants to keep up with the fast pace of the class. The Study The proposed study aims to further explore the motives for the participation of the elderly in dance activities as well as the reasons why the elderly choose to give up dance. The data collected will be useful for community leaders who wish to engage the elderly in long term dance classes. This is particularly important as the number of elderly is greater than ever before.

Pelvic actinomycosis is a chronic, progressive, granulomatous and suppurative disease caused by an anaerobic or microaerobic Gram-positive organism, not fungi. Actinomyces species exhibit branching, filamentous growth and appear in the human skin, oral cavity, gastrointestinal tract. Actinomyces infection in human is relatively rare, however, prolonged use of an intrauterine contraceptive device (IUD) is a well known risk factor of pelvic actinomycosis. Pelvic actinomycosis can mimick pelvic malignancy leading to mutilating surgical excision, and diagnostic problems necessitated a laparotomy in many patients. The pathohistological diagnosis is based on the characteristic microscopic image and specific staining of sulfur granule. Adequate surgical excision and administration of antibiotics show good prognosis. We experienced 2 cases of pelvic actinomycosis with the intestinal obstruction, confirmed pathohistologically after laparotomy.

The malignant lymphomas are neoplastic transformation of cells that reside predominantly in lymphoid tissues. The two major variants of malignant lymphoma are non-Hodgkin's lymphoma and Hodgkin's disease. Although both of these tumors infiltrate reticuloendothelial organs, their biologic and clinical behaviors suggest that they are probably not related. More than 90% of all cases of non-Hodgkin's lymphomas are of B-cell derivation. This observation is based upon the expression of B-lineage-restricted antigens as well as clonal rearrangements of immunoglobulin heavy and light chain genes. The malignant lymphoma localized in uterine cervix is rare and characteristically symptom-free expressed. We experienced a case of malignant lymphoma originated from uterine cervix, so we report with a brief of literature.
