BACKGROUND: Complete resection by the surgery has been selected as the treatment of choice in lung cancer patients, but in cases of recurrence after excision or inoperable cases, the importance of anticancer chemotherapy has been emphasized. If one can select a set of the sensitive chemotherapeutic agents before anticancer chemotherapy, it will give more favourable results. Subrenal capsular assay has been recognized as a useful in-vivo chemosensitivity test of thoracic and abdominal tumors and it can be done in a short time for a rapid interpretation of tumor responsiveness to anticancer chemotherapeutic drugs. It has been reported that various kinds of cancer cells can be implantable to the kidney, but so far there is no comparative study of xenogeneic cell implantation on liver, spleen and kidney. The author implanted the human lung cancer cells under the capsule of S.D rat's liver, spleen and kidney respectively and compared the pattern of growth and histology. MATERIAL AND METHOD: After incubation of human lung cancer cell line (SW-900 G IV) in RPMI 1640 (Leibovitz L-15 medium) culture media, 3x3x3 mm size fibrin clots which contain 108 cancer cells were made. Thereafter the fibrin clots were implanted at subcapsule area of liver, spleen and kidney of S.D. female rat. For immune suppression, cyclosporin-A (80 mg/Kg) was injected subcutaneously daily from post-implantation first day to sixth day. The body weight was measured at pre and post implantation periods. The growth pattern and the size of tumor mass were observed and the pathologic examination and serum tumor marker tests were performed. RESULT: Body weight increased in both of control and experimental groups. Serum Cyfra 21-1 was not detected. Serum levels of CEA and NSE revealed no significant change. The SCC-Ag increased significantly in implanted group. The growth rate of human lung cancer cells which was implanted on spleen was higher than on liver or kidney. The surface area, thickness, and volume of tumor mass were predominant at spleen. The success rates of implantation were 80% on kidney, 76.7% on spleen and 43.3% on liver. Pathologic examination of implanted tumors showed characteristic findings according to different organs. Tumors that were implanted on kidney grew in a round shape, small and regular pattern. In the spleen, tumors grew well and microscopic neovascularization and tumor thrombi were also found, but the growth pattern was irregular representing frequent daughter mass. Human lung cancer cells that were implanted in the liver, invaded to the liver parenchyme, and had low success rate of implantation. Microscopically, coagulation necrosis and myxoid fibrous lesion were observed. CONCLUSION: The success rate of implantation was highest in the kidney. And the mass revealed regular growth that could be measured easily. The SCC-Ag was presented earlier than CEA or Cyfra21-1. The Cyfra21-1 was not detected at early time after implantation. The best model for tumor implantation experiment for chemosensitivity test was subrenal capsular analysis than liver and spleen and the useful serum tumor marker in early period of implantation was the SCC-Ag.

A 43-year-old woman who had had an invasive mole 5 years previously required emergent pulmonary embolectomy under cardiopulmonary bypass. Curative resection was impossible because the tumor invaded the right main pulmonary artery and left lower pulmonary artery. The pathologic diagnosis made by the tumor emboli specimens was choriocarcinoma. The patient received post-operative chemotherapy over a 6-month period and had complete remission. Although rare, choriocarcinoma should be considered in the differential diagnosis of fertile women presented with pulmonary embolism.

Two rare cases of intraventricular arachnoid cyst locating in the posterior portion of the third ventricle are presented. A diagnosis was based on the radiological and operative findings and the microscopic features. Cyst wall fenestration by a direct approach resulted in good outcome. The orgin and the management of arachnoid cyst are discussed.

PURPOSE: To describe the use of an emergency department (ED)-based, in-depth injury surveillance system to determine the incidence and mechanism of preschool children injury. METHODS: We prospectively studied and registered injured children under 7 years old, (n=5,921) whose injuries resulted in ED treatment from August 2006 to July 2008. We upgraded the checklist surveillance items, included place, accident mechanism, and agent factors. The ED physicians recorded the injury data on checklists in real time as they gave the ED orders. The recorded data were stored in computer networks and automatically coded, which enabled access to the raw data sources. The statistical data were calculated in detail by using relative frequency distribution from the raw data. RESULTS: A total of 29,548 injured patients visited the ED from August 2006 to July 2008. Preschool children injuries, except those from traffic accidents, were 5,921(20.0%). The most common sources of injuries were from blunt trauma (37%), slips(17%), and falls(16%). Among those admitted to our hospital, fall injuries and inhalation of foreign body accidents accounted for 7.6% and 7.5%, respectively. The larger proportion of fall injuries occurred from a height of less than 1 meter(82.2%). The frequency of injury mechanism differed according to age: fall(35%), blunt(19%), and burn(14%) were noted under 1 year old, compared to blunt(34%), fall(14%), and slip(13%) from between 1 to under 3 years of age, and blunt(37%), slip(19%), and fall (11%) between 3 to under 7 years of age. CONCLUSION: The ED-based preschool children injury surveillance system could provide a useful and efficient method to determine injury incidence and injury-related factors.

BACKGROUND: Investigation of the factors affecting blood donation practice is essential to develop the ways of making blood donation campaign, as well as efficient and facilitating blood donation practice. A few studies has been made concerning the factors affecting blood donation in Korea. METHODS: 637 participants were examined using self-administered questionnaires including demographic variables, experience, knowledge and attitude for blood donation and others. RESULTS: 51.5% of participants had experienced the blood donation. Students who donated blood in high school days showed tendency to donate blood more than those who didn t donate blood in high school days. Students who had more knowledge and desirable attitude about blood donation experienced more blood donations. CONCLUSION: It is necessary for adolescents to take the opportunity of blood donation. It is important to clarify factors affecting blood donation practice and to encourage the public education and campaign which enable public has accurate knowledge and positive attitude about blood donation.
