천영국,김영태,홍수진,김진오,조주영,이문성,심찬섭 순천향의학연구소 2001 Journal of Soonchunhyang Medical Science Vol.7 No.1
Background/Aim: It is difficult to dignosis of Borrmann type 4 gastric cancer at the early stage, because of its special morphology. Most of the cases have been detected at the advanced stage with poor survival rate. We reviewed patients with advanced gastric cancer, to define clinicopathologic characteristics of Borrmann type 4 gastric cancer comparing other types of gastric cancer. Methods: 1033 patients with advanced gastric cancer were divided into two groups, consisting of 50 patients with Borrmann type 4 gastric cancer, and the remaining 983 patients with all other types of gastric cancer, which were then compared clinicopatologically. Results: The proportion of Borrmann type 4 gastric cancer to advanced gastric cancer was 4.48%(50/1,033). The patients with Borrmann type 4 gastric cancer to advanced gastric cancer was 4.48%(50/1,033). The patients with Borrmann type 4 gastric cancer were composed 20 males and 30 males and revealed the highest frequency 3rd decade (24.0%) in age (range 26-78). In giant folds group (n=27), the number of poorly differentiated cell type, lymph node metastasis, peritoneal seeding were 20 (74.1%), 17 (63,0%), 12 (44.4%). In non-giant folds group (n=23), the number of poorly differentiated type, lymph node metastasis, peritoneal seeding were 17 (73.9%), 15 (65.2%), 6 (26.1%). Rate of tumor invasion in serosa and beyound serosa was 88.9% in giant fold group, 63.0% in non-giant fold group. Surgery was performed in only 32% as a modality of treatment (vs. 82.5%). Characteristics findings of Borrmann type 4 gastric cancer in EUS showed a thickening of the third (submucosa) and fourth (muscularis propria) layers in 72% of 50 patients, and a well preserved five-layered gastric wall structure in 33 patients. Conclusions: We concluded that Borrmann type 4 gastric cancer was diagnosed more in females, as a more advanced disease, early detection was needed. And endoscopic ultrasonography is useful for diagnosis of Borrmann type 4 gastric cancer in the cases of suspicious results of gastroscopy.

장재영,천영국,최우봉,김진오,조주영,이준성,이문성,심찬섭 순천향의학연구소;Soonchunhyang Medical Research Institute 2000 Journal of Soonchunhyang Medical Science Vol.6 No.1
Background/Aims: Retroperitoneal fibrosis is a fibrosing disease process which frequently develops ureteral obstruction. Malignant retroperitoneal fibrosis has been reported that various types of cancer including cancer of the breast, stomach, prostate, lung, cervix, uteri, colon, pancreas, ovary, and even Hodgkin's disease. While the pathogenesis remains obscure, small foci of metastatic neoplasm in the retroperitoneal space can elicit a desmoplastic reaction in secondary form to malignancy. Methods: Recently we experienced 7 cases of retroperitoneal fibrosis with advanced gastric cancer. So, we report 7 cases of retroperitoneal fibrosis with clinical and radiologic characteristics. Results: The most common signs and symptoms were related irreversible renal dysfunction. The urologic finding noted medial deviation of the involved ureters and hydronephrosis Conclusions: Clinical manifestations are abdominal pain, back pain, hydronephrosis, and uremia. When sudden back pain and hydronephrosis develop in advanced malignancy, physicians should be considerd for retroperitoneal fibrosis.

The cultural interchanges have been dramatically increased between Korea and China since the diplomatic agreement on the 24th of August, 1992, Among the several discussions between the two countries, particularly building up Korea traditional garden will take concrete shape in Kwan-dong in China. These followings are the basic plans. First, the project approaches the garden as a place for the interchange and the cooperation between the counties, and where people can experience Korea traditional garden. Secondly, it is plotted to express the distinct character and originality of Korea traditional garden. Third, it applies the same materials, subject matters and the same construction method of Korea traditional garden. We can use the most similar materials if it is not possible. Fourth, the project is plotted to make the efficient use of the land form to decrease the damage of natural environment.

The College of Engineering was specialized to have a sole function for supplying technical high school teachers in 1977 and referred to as the College of Industrial Education according to the Government's policy. The economic impact mainly due to the oil-crises caused a severe problem to this college, namely discrepancy of supply to demand scale. Accordingly the number of student enrollment was to be fluctuated from 479 in 1979 through 800 in 1979 and 900 in 1980 to 430 in 1981. And the engineering departments have been attached to this Engineering Education College since 1981. These circumstanses met singnificant inefficiency in facility operation. This program aims at providing an overall relocation of the college facilities and preparing the practical system to make the joint-operation possible taking into account circulation, academic stream, budget, maintenance, etc. However this study could not get optimal spacing but some trade-off, considering the current situation.

Apoptotic Effect of Co-treatment with Chios Gum Mastic and HS-1200 on G361 Human Melanoma Cell Line
Young-Joo Hur,Young-Ki Kim,Hyun-Ho Kwak,Gyoo-Cheon Kim,Seung-Eun Lee,In-Ryoung Kim,Chul-Hoon Kim1,Bong-Soo Park 대한해부학회 2009 Anatomy & Cell Biology Vol.42 No.2
Chios gum mastic (CGM) is a resinous exudate obtained from the stem and the main leaves of Pistacia lenticulus tree native to Mediterranean areas. Recently it reported that CGM induce apoptosis in a few cancer cells in vitro. Bile acids and their synthetic derivatives induced apoptosis in various kinds of cancer cells and anticancer effects. It has been reported that the synthetic chenodeoxycholic acid (CDCA) derivatives showed apoptosis-inducing activity on various cancer cells in vitro. This study was undertaken to investigate the synergistic apoptotic effect of cotreatment with a natural product, CGM and a CDCA derivative, HS-1200 on G361 human melanoma cells. To investigate whether the co-treatment of CGM and HS-1200 compared with each single treatment efficiently reduced the viability of G361 cells, MTT assay was conducted. To investigate augmentation of apoptosis in G631 cells co-treated with CGM and HS-1200, DNA electrophoresis, Hoechst staining, proteasome activity assay, flow cytometry, Westen blot analyses, immunofluorescent staining and confocal microscopy were performed. In this study, G361 cells co-treated with CGM and HS-1200 showed several lines of apoptotic manifestation such as nuclear condensations, DNA fragmentation, the reduction of MMP and proteasome activity, the decrease of DNA content, the release of cytochrome c into cytosol, the translocation of AIF and DFF40 (CAD) onto nuclei, activation of caspase-9, caspase-3, PARP and DFF45 (ICAD), and up-regulation of Bax whereas each single treated G361 cells did not. Although the single treatment of 40 μg/mL CGM or 25 μM HS-1200 for 24 hrs did not induce apoptosis, the co-treatment of them induced prominently apoptosis. Therefore, combination therapy of CGM and HS-1200 could be considered, in the future, as an alternative therapeutic strategy for human melanoma.

Outcome of Photodynamic Therapy for Early Esophageal Cancer
( Young Koog Cheon ),( Wan Jung Kim ),( Joo Young Cho ),( Joon Seong Lee ),( Moon Sung Lee ),( Chan Sup Shim ) 대한소화기기능성질환·운동학회 2007 Gut and Liver Vol.1 No.2
Background/Aims: Endoscopic treatment as an alternative to surgery has become increasingly popular for improving the quality of life. Although photodynamic therapy (PDT) has been used for the endoscopic treatment of digestive cancer, its curative efficacy remains unclear. We evaluated the curative efficacy of PDT in superficial esophageal cancer in inoperable patients. Methods: Ten male patients with histologically proven early esophageal cancer (surgery was contraindicated for age > 80 years, surgery was contraindicated, Karnofsky performance status of at least 30%, or refusal of surgery) were intravenously injected with a hematoporphyrin derivative (2 mg/kg), and PDT was performed 48 h later. The response to treatment was assessed by gastroscopy with biopsies. Results: The mean follow-up period was 27.6 months (range, 9.6-58.7 months). Endoscopic ultrasonography revealed that all ten cases were at tumor stage T1. Complete remission (CR) to initial and subsequent PDT was observed in all patients. For the CR cases, the recurrence rate was 10% (1/10) and the time from initial PDT to recurrence was 9.6 months. Conclusions: For patients in whom surgery is risky or refused, PDT may represent an acceptable alternative treatment modality, especially for superficial esophageal cancer without lymph node metastasis. However, a study involving long-term follow-up in a large population is needed for confirmation. (Gut and Liver 2007;1:126-131)

PM Emission Characterizations of Waste Biomass Through Pre-Treatment
( Young-joo Lee ),( Young-chan Choi ),( Sea-cheon Oh ),( Kyong-hwan Lee ) 한국폐기물자원순환학회(구 한국폐기물학회) 2019 ISSE 초록집 Vol.2019 No.-
Nowadays, it is widely considered that biomass combustion technology is attractive for removing carbon dioxide emissions, and therefore could become a viable option for the next generation co-combustion power plants with coal. Among biomasses, the faster growing herbaceous biomass is relatively inexpensive as a solid fuel, but has higher mineral contents (especially high levels of alkali metals) than that of a lignocellulosic biomass which leads to ultrafine particle emissions during combustion. We hereby propose a dual stage treatment method to extract the inherent minerals in an herbaceous biomass prior to the combustion test which consists of initially a basic solution treatment and a sequentially acidic solution treatment. To verify the proposed method, we investigated the variations in both the mineral contents and the PM, NOx and SO2 emissions between raw- and treated samples. The experimental results show that sodium, potassium and chloride in the treated herbaceous sample, which are the major minerals that generate ultrafine particles, were removed up to 96.3, 99.4 and 98.3%, respectively. The proposed method is more effective for herbaceous biomasses due to its higher Brunauer-Emmett-Teller (BET) value. Furthermore, the treated herbaceous biomass is even environmentally superior to raw lignocellulosic biomasses currently used in co-combustion power plants with coal in terms of the PM2.5, NOx and SO<sub>2</sub> emissions, of which rejection are measured as 60, 25 and 46%, respectively. These results will help the energy and cost savings in De-NOx (selective catalytic reduction, SCR system) and De- SO<sub>2</sub> (scrubber) units.
