N/A Background : Nonspecific elevations of CK-MB, cTnT have been well known in patients with chronic renal failure(CRF) on maintenance hemodialysis. It has been suggested that recently developed cTnI seldom shows nonspecific elevations in these patients. Status of CRF patients can be divided into three groups: predialysis group, hemodialysis group and peritoneal dialysis group. Until now, most researchers have studied CK-MB, cTnT and cTnI only in CRF patients receiving maintenance hemodialysis. No previous studies have ever compared the differences of the nonspecific positivity of CK-MB, cTnT and cTnI according to the different status of CRF patients. Methods : Nonspecific positive ratios of cTnI, cTnT, & CK-MB in were evaluated 20 predialysis patients, 13 CAPD patients and 20 hemodialysis patients. No one had had any evidence of myocardial ischemia during the previous 3 months before the study entry. The predialysis group was again divided into two groups according to the cut off level of serum creatinine of 3.0 mg/dl. Authors also compared the nonspecific positive ratios of cTnI, cTnT, CK-MB between diabetic CRF group and non diabetic CRF group. The sensitivity, specificity and false positive ratios of each enzymes were examined on and 6 hours after arrival in 21 CRF patients who visited the emergency room with the complaint of chest pain. Results : 1) There were no nonspecific significant elevations of cTnI in CRF patients regardless of the status of CRF. But there were significant nonspecific elevations of CK-MB, cTnT in them. It was more marked in cTnT especially with the cut-off value of 0.1 ng/ml. 2) Nonspecific positive ratios of cTnT was significantly increased in diabetic CRF patients. 3) The sensitivity and specificity of cTnI were 100% and 93.3% each, which were significantly higher than those of CK-MB(83.3%, 66.7%) & cTnT(66.7%, 53.3%). Conclusion : In CRF patients, the nonspecific positive ratios of CK-MB, cTnT were higher than that of cTnI, and only cTnI did show significant specific elevations in all the CRF patients with acute myocardial infarction. It is likely that the status of CRF patients, dialysis mode, the sampling time point would not give significant changes in the nonspecific positive ratios of CK-MB, cTnT and cTnI.(Korean J Med 58:204-212, 2000)
인터넷비지니스에서의 서비스퀄러티가 고객만족에 미치는 영향에 관한 연구

At first, I have to classify exactly the typology of interned business. I have to define the internet business. Internet business is the cyber space which the customers require the service. communication information A/S etc in computer. There must be clear differences about the service quality between conventional business transactions and electronic commerces. I would try to analyse the determinants of the service quality on electronic commerces. So. I supposed that there could be 4 types of determinents named as information. technology, products, logistical support. The internet business must have the several determinents which will evaluate the service quality. These determinants are intermediary variables and this ones can influence the user satisfactions. The consumers could be immediately affected by the service quality of internet business and they would appreciate the measuring dimensions of the service quality by some preferences. These dimensions are definitely different from the ones of service quality on the traditional transactions. In some cases, the personal experiences can be included in the service quality and they can be more valuable in point of Influencing the user satisfaction. After establishing the research model and hypotheses, I am planning to analyse the results of field survey. Of course, I think I should prepare the survey questionnaires like SERVQUAL which could be respondent to internet environment. In the future, all consumers over the world would be affected by internet business environments because any transactions in any area would be dealer with internet system. At result, all internet transactions would be appreciated by the service quality or service experiences. The better service quality would be or the more movable service experiences would be, the consumers were easy to satisfy with the internet business and visit it again. In this time, the enterprise could advertise its brand values(business values) to all consumers.
혈액투석으로 전환하여 성공적으로 치료한 복막투석치료중인 당뇨병성 만성신부전환자에서 발생한 고삼투압성 혼수

Continuous ambulatory peritoneal dialysis(CAPD) is now the most important and effective therapeutic modality as well as hemodialysis(HD) and renal transplantation in patients with chronic renal failure. It is frequently recommended to diabetic renal failure patients because of poor, athersclerotic vascularity of them. Hyperglycemia and obesity are not uncommon complications of CAPD therapy. But there were only few reports of very severe hyperglycemia or hyperosmolar coma in CRF patients on CAPD therapy, especially with 7% dextrose CAPD dialysate in foreign countries in the past. Moreover, no specific management for hyperosmolar coma is established in those situations yet. In Korea, only three cases of hyperosmolar coma in non diabetic renal failure patient on CAPD therapy have been reported in one case report. And only one case among them whose CAPD therapy was changed to HD survived. Authors also experienced a case of diabetic hyperosmolar coma treated successfully with conversion to HD in chronic renal failure patient on CAPD therapy. So we report this case with a review of literature. Taken together with this case and review of literature, changing CAPD therapy to HD is regarded to be an important part of treatment when hyperosmolar coma develops in chronic renal failure patients.

오소리 생식 후 발생한 선모충증(Trichinosis) 1예

Trichinosis is a worldwide parasitic infection developed after the ingestion of uncooked meat containing viable larvae of the nematode Trichinella spiralis. Fever, myalgia, periorbital edema and eosinophilia are characteristic features and most infections are mild and asymptomatic, but a few cases have a severe clinical course due to cardiac or cerebral complications. This parasitic infection is spread in nature among a large number of carnivorous animals, human being an incidental host. While the highest prevalence is in North America and Europe, some outbreaks of trichinosis have been reported in the areas of Southeast Asia, China and Japan recently, but it has not been reported in Korea yet. We experienced a case of trichinosis with typical clinical features and laboratory findings of trichinosis after eating a raw liver and blood of wild badger which was poached in Chi-ri mountain.
