Injuries are serious problem common to all societies. Yet even within a single community, groups of injured persons differ as to the nature and severity of their injuries. The difficulty of adjusting for such variations has hampered scientific study of injured persons. Neverthless it is essential to take differences in severity of injury into account when comparing the morhidity & mortality of various groups for the purpose of evaluating their emergency & subsequent care. In order to provide the guidelines of mass emergency care & transportation, the authors analysed the 206 injured patients of train accident at Kyungsan, May 14th, 1981 and compared mortality with severity and body system of the injuries. The results were obtained as follows: l. Of 206 injured patients, most were young people & the ratio of male & female was about equal. 2. Extremities were the most frequently injured parts of body system & single injury was more common. 3. According to most severe injury of AIS, 78% of injured persons belonged to below AIS grade 3 and none was dead. 4. Average ISS of survival groups was 6 and that of death groups was 34. None was dead below average ISS of 15. 5. Death rate was higher for patients above 50 years of age, than that for young patients and there was no age difference in mortality for ISS of 50 and higher. 6. Majority of death group were invclved in multiple injuries and major cause of death were chest and head injuries. 7. Average ISS and age of hospital death group were less than those of DOA group. 8. The authors thought that it was necessary to estahlish Emergency Service System including training and education of both professionals and the pulic, hospital categorization, communication and transportation system for the mass emergency care.

Eighty cases of malignant effusion were cytologically studied to elucidate the incidence of primary tumor site and cytologic characteristics of each tumor types. Eighty fluid specimens were composed of 43 ascitic, 35 pleural, and 2 pericardial effusion and primary tumor site had been confirmed by histology. The frequent primary sites were stomach (22 cases, 28%), lung (21 cases, 26%), ovary (11 cases, 14%), liver (7 cases, 9%), and breast (4 cases, 5%). The principal malignant tumors were adenocarcinoma (56 cases, 70%), squamous cell carcinoma (7 cases, 9%), liver cell carcinoma (7 cases, 9%), small cell carcinoma (4 cases, 5%), and non-Hodgkin's lymphoma (4 cases, 5%). The distinctive cytologic findings according to primary tumor types were as follows; the gastric adenocarcinomas were mainly characterized by isolated cells and irregular clusters sometimes with signet ring cells. Papillary serous cystadenocarcinoma of ovary showed frequently papillary clusters and occasional psammoma bodies. Breast carcinoma of ductal type showed cell balls with smooth margins. Colonic adenocarcinoma showed rather irregular clusters o palisading pattern of cylindrical cells. Metastatic squamous cell carcinoma, liver cell carcinoma, small cell carcinoma, and non-Hodgkin's lymphoma showed also characteristic features. These findings indicate that the cytological features observed in the great majority of malignant effusion are similar to those of primary tumor types, which are very helpful to indentify the primary tumor site.

7.Homograft or Autograft Valve Replacement.
Hanyang Medical Reviews 2007;27(2):44-48
Since 1960s, when Ross and Barratt-Boyes introduced homograft replacement of the aortic valve, the valvular replacement using homografts or autografts has been gained increasing acceptance. Aortic or pulmonary valves (with or without associated vascular conduits) transplanted from one individual to another have exceptionally good hemodynamic profiles, a low incidence of thromboembolic complications without chronic anticoagulation, and a low re-infection rate following valve replacement for endocarditis. The homografts were primarily used for complex congenital reconstructions in infants, and children. However, more recently they have been increasingly used in adults requiring aortic valve replacement. Even though there are many advantages, the lack of available homografts, as well as concerns of long-term stenotic problems, may limit their use.

10.Characteristics of Training Materials for Successful Microvascular Anastomosis and Preclinical Assessment of The Surgical Skills.

Korean Journal of Cerebrovascular Surgery 2007;9(4):243-246
The need for microvascular anastomosis is on the increase for the prevention or treatment of hemodynamic stroke or planned major vessel occlusion for the treatment of complex intracranial vascular lesions or tumors. The surgical skill of the microsurgeon is the most important factor for successful microvascular anastomosis. Thus, surgical experience in the laboratory is essential. With a review of the literature, we demonstrate characteristics of several training materials for the laboratory and preclinical assessments of surgical skills.
