A case-control study was conducted to investigate the association between the risk of cancer and selenium concentration in blood and toenails. Seventy three patients and two hundreds eighty three controls were selected at the Yeungnam University Hospital between May and September in 1991. The selected cases were patients who had been hospitalized for stomach or colon cancer at the Department of General Surgery. The controls were people who visited to check physical examination at the Automated Mediscreening Center. The selenium concentration in whole blood and toenails were measured by atomic absorption spectrophotometer equipped with graphite furnace atomizer. The following information was ascertained for all cancer patients and controls: sex, age, body mass index, blood pressure, total serum cholesterol, and history of smoking and drinking. The mean selenium concentration in blood and toenail for all cancer patients were 143.6±10.8 µg/l and 1.04±0.62 µg/g and for the controls. 167.0±14.5 µg/l and 1.15±0.55 µg/g, respectively. The difference in blood and toenail selenium concentrations of the two cancer sites was not statistically significant. Metastasis did not influence the concentration of selenium in blood and toenails. In the multiple logistic regression analysis, the blood selenium concentration (aOR: 0.888, 95% CI: 0.860-0.918), age, BMI and total serum cholesterol were significant variables for risk of cancer, but the selenium concentration in toenail was not shown to be a significant variable in this regression analysis. The coefficient for blood selenium concentration adjusted for age, sex, diastolic blood pressure, total serum cholesterol, body mass index and smoking was -0.1184 (p<0.01). These findings suggest that low selenium concentration is associated with gastrointestinal cancers. Further epidemiologic studies including important variables such as other antioxidant micronutrients will be necessary.

PURPOSE: The main object of treatment in chronic occlusive arterial disease is to increase blood flow and to prevent progress of ischemic ulcer. In case of the symptoms and signs such as rest pain, ischemic ulcer and gangrene with poor angiographic distal run-off, conservative medical treatment is recommended. Argatroban (Novastan(R) ) has an arginine structure, is the first selective antithrombin in the world, showing the inhibitory effect of thrombin-induced fibrin formation, platelet aggregation and vasoconstriction. METHOD: From September 1995 to January 1999, 39 patients with chronic arterial occlusion as subjects, ulcers, resting pain and feelings of coldness participated in Novastan treatment in 3 institutions (Department of Surgery, Yeungnam University College of Medicine, Department of Surgery Vascular Division, Ulsan University College of Medicine and Asan Medical Center, Department of Surgery, Gachon Medical School) and 30 patients completed the study:thromboangitis obliterance (TAO) in 19 and atherosclerosis obliterans (ASO) in 11 cases. Administration dose was 20 mg (2 amples, q.d or b.i.d) and medicated for consecutive 4 weeks. To detect the changes of symptoms, ulcer size and occurrence of side effects, inquiries, photography and laboratory tests were checked at prior to medication and 2, 3 and 4 weeks after medication. RESULT: There were 29 men and 1 women, ranging in age from 18 to 80 years old with mean of 50 years old and in body weight from 44 to 86 kg with mean of 64 kg. Improvement rate on ulcer size and granulation appearance was 73.3% (22 cases/30) and 86.7% (26 cases/30) respectively. General improvement rates were 76.7% (23 cases/30), general safety rates were 97.4% (38 cases/39), and utility rates were 70.0% (21 cases/30). Side effects were observed in 3 cases (7.7%), and abnormal changes in laboratory tests were observed for 15 items in 9 cases. But there noted no significant side effects and abnormalities in laboratory tests. CONCLUSION: Argatroban had a beneficial effect in improving such clinical symptoms as ischemic ulcer, resting pain and the feeling of coldness, accompanying chronic arterial occlusion, it causes no serious side effects and it shows high clinical utility.

PURPOSE: Buerger's disease (Thromboangiitis obliterans, TAO) is characterized by non- atheromatous inflammatory disease, and segmental inflammatory thrombotic occlusions of the small & middle-sized arteries and veins of the upper or lower extremities. Any epidemiological study of Buerger's disease in Korea has not been carried out until now. This study was undertaken to investigate the incidence of Buerger's disease in Korea among the patients suffering with arterial disease. METHODS: We collected and analyzed the data on 11,128 patients who were admitted to or visited the participating 22 hospitals for chronic arterial diseases throughout the major region of the South Korea from January 1986 to December 2003. The clinical diagnostic inclusion criteria for Buerger's disease were the followings: (1) a history of smoking or tobacco abuse; (2) an age of onset less than 50 years; (3) infrapopliteal, segmental arterial occlusions with sparing of the proximal vasculature; (4) frequent distal upper extremity arterial involvement (Raynaud's syndrome or digital ulceration) or-superficial phlebitis; and (5) the absence of arteriosclerotic risk factors other than smoking. RESULTS: The incidence rate of Buerger's disease among the arterial disease (11,128 patients) was 93 patients (0.83%) when the strict criteria of Shionoya was applied. 699 male-patients (6.55%) and 30 female patients (4.12%) who met the less strict criteria (the extended clinical diagnostic criteria group) were also reviewed. The 4th and 5th decades were the most common ages with-249 patients (34.2%) and 222 patients (30.5%) respectively, being found at these ages. The mean age was 40.4+/-1.6 years (age range: 16~83 years) and this was similar in both the strict criteria group and the less strict criteria group. CONCLUSIONS: This study suggests there was a low incidence of Buerger's disease in Korea among the patients who visited the participating hospitals when the strict diagnostic criteria were used. The incidence was lower than expected even when the less strict criteria were used. The more accurate incidence of Buerger's disease among the general population can be obtained by performing careful prospective study that is participated in by not only vascular surgeons, but also the other medical specialists with utilizing the strict diagnostic criteria.

While endovascular aneurysm repair (EVAR) is prevailing for the treatment of abdominal aortic aneurysm (AAA) in modern vascular practice, PURPOSE: we conducted nationwide questionnaire survey to investigate the current status of AAA treatment and their results in Korea. METHOD: We reviewed the replies from 28 hospitals (33 departments) to the questionnaire inquiring annual number, clinical features, mode of treatment and results of AAA patients during the period from Jan. 2000 to Jul. 2004. Results: 980 AAA patients were reported including 292 ruptured AAA (29.8%) and 688 non-ruptured AAA (70.2%). For treatment of AAA, 834 (85.1%) surgical repairs (SRs) and 111 (11.3%) endovascualr aneurysm repairs (EVARs) were performed while 35 patients (3.6%) died of AAA rupture before operation. The locations of AAA were infrarenal in 889 (90.7%), juxtarenal in 62 (6.3%), and suprarenal in 29 patients (3.0%). Among 834 patients undergoing SR, 577 patients (69.2%) had non-ruptured AAAs and 257 patients (30.8%) had ruptured AAAs. Mean operative mortality rate was 4.1% after elective SRs, 30.7% after SR for ruptured AAAs, and 2.3% after EVARs. The reported brand name of stent graft devices were various including domestic custom-made in 56 (50.5%), imported brand in 18 (16.2%) while 37 (33.3%) stent grafts were not reported their brand name. The frequencies of type I and III endoleaks after EVAR were reported 5.8% and 5.8% respectively in 86 patients with an available data. CONCLUSION: SR has been used as a major treatment option in Korea for the treatment of AAA patients while EVAR is increasing. The mortality rate of SR of AAA was comparable to western multi-center trial reports but mortality or morbidity rates of EVAR were unable to know in this questionnaire survey.
