Choriocarcinoma of the gastrointestinal tract is rare. Among them, that of the stomach is the most common. Six cases of choriocarcinoma of the colon were found in the review of the literature. All of these previously reported cases had multiple metastatic foci in the liver, lung, lymph nodes and the prognosis seemed to be very poor. Therefore we think that choriocarcinoma of the colon should be distinguished from conventional adenocarcinoma. A 66-year old female patient, described in this case, was operated on under the impression she was suffering from acute appendicitis. The resected ascending colon revealed extensive hemorrhagic necrosis and perforation with fibrous adhesion in the cecum. On the cut section, the mural tumorous thickening was not definite. Histologically, the tumor showed a focus of typical adenocarcinoma arising from glandular epithelial cells, which were transformed into highly anaplastic tumor cells. There were frequent vascular invasions of tumor cells, similar to syncytiotrophoblasts. In the immunohistochemical stains, both glandular and highly anaplastic tumor cells reacted with cytokeratin. The glandular cells were also reactive for carcinoembryonic antigen (CEA) and anaplastic tumor cells for human chorionic gonadotrophin (hCG). This is the first report of choriocarcinoma of the colon in Korea. We describe this case with a review of the literature.

In tiis study, an expenmental model of glaucoma filtering surgery in rabblts was used to evaluate the effect of single intraoperative application of Mitomycin Full-thickness filtering surgery, posterior lip sclerectomy, was performed after application of 0.5mg/ml Mitomycin-soaked Week-Cel(TM) sponge for 5 minutes in one eye of 15 pigmented rabbits and was irrigated copiously with balanced salt solution(BSS(TM)). The same procedure was done in the contralateral eye as a control, using BSS(TM). In Mitomycin-treated group, the filtering blebs were more prominent with sparse vascular tissues and were maintained through postoperative 8 weeks or more. Histologically, there loas was amount of inflammatory reactions in Mitomycin-treated group. The fibroblastic activity and proliferations of the collagen were also suppessed markedly in Mitomycin-treated group. These results suggest that a single intraoperative application of Mitomycin can be used adjunctively to improve the success rate of glaucoma filtering surgery.

OBJECTIVES: This study was designed to evaluate the problems of pre-hospital Emergency medical care system (EMS) in workplace. We analysed 25 fatal work-place injuries during the recent 4 years and the work-place EMS of 8 enterprises located in Masan-city, Changwon-city and Kuje-island. METHODS: The safety managers and the members of Dept. of safety in the labor unions were interviewed about the work-place EMS. And we investigated on the injury reports, the work-place medical-room records and the medical records of emergency center for fatal 25 cases. RESULTS: The enterprises had the at-risk machines and processes, volatile materials and high-altitude working processes. There were duty doctors in only 3 enterprises but a few duty nurses or health-care providers in the others. The time spent for the education to the workers on safety was 24hrs/yr in 3 enterprises in 1998 but less than Bhrs in the others. There were medical service center in all enterprises but the ambulances in three. The time for activation of the ambulance was ranging from 5 minutes to 10 minutes in 6 enterprises, and from 10 minutes to 30 minutes in two. The patient transportation to the emergency center was possible within 30 minutes in all enterprises but there were no equipments for airway maintenance and shock management in all enterprises. The 15 (60%) fatal injuries were occurred at one enterprise. The 64% of casualties had the duration of job-employment more than 10yrs and the 68% were suffered the typical type of work-place injury as descending injuries, collisions and falls. Most of all primary calls for rescue were concentrated on the fire-service agencies. But in 85% of fatal injtories, the tome for the activation of ambulance was more than 10 minutes and no emergency care was taken in the field in 48 percent of casualtles. The transportation time to the emergency center was more than 30 minutes in 50 percent. It toolk from injury to death was less than one hour in the 40 percent of all cases, and from one hour to four in the 50 percent. The causes of death in the 68 percent were the head-and-neck injuries or thoracic injuries. CONCLUSIONS: We found that there was Insufficiency of the education associated with work-place injury for workers, manpower and facilities, equipments related to the work-place EMS, the problems of the delay in transportation system.

BACKGROUND: The purpose of this study was to analyze the relationships between cardiorespiratory fitness and body mass index (BMI), metabolic syndrome risk factors, homeostasis model assessment-insulin resistance (HOMA-IR), and high sensitivity C-reactive protein (hsCRP) in male high school students in Korea. Furthermore, the effects of the cardiorespiratory fitness levels on these four factors were examined. METHODS: The level of cardiorespiratory fitness, BMI, percent body fat, waist circumference (WC), systolic blood pressure, glucose, triglycerides (TG), high-density lipoprotein-cholesterol (HDL-C), HOMA-IR, and hsCRP of 227 male high school students were measured. Analyses of multiple correlation and simple regression were applied. RESULTS: The results showed that the level of cardiorespiratory fitness correlated negatively with BMI, percent body fat, WC, TG, and HDL-C, in addition to HOMA-IR and hsCRP, and strongly influenced BMI, percent body fat, WC, TG, HDL-C, HOMA-IR, and hsCRP. Comparative analysis of our subjects showed that higher cardiorespiratory fitness levels had positive effects on BMI, metabolic syndrome risk factors, HOMA-IR, and hsCRP. CONCLUSIONS: This study found that there are close correlations between cardiorespiratory fitness and BMI, metabolic syndrome risk factors, HOMA-IR, and hsCRP. It also showed that, compared to lower levels of cardiorespiratory fitness, higher levels had beneficial effects on BMI, metabolic syndrome risk factors, diabetes, and cardiovascular disease risk factors.
