Background : Nowadays, it is possible to prolong the life. And to improve the quality of life of the dying patients, they need to receive not only the physical, pscychological, social and spiritual care but also comprehensive and continuous care. Also, doctors have to consider many ethical issues especially in the dying patients. The purpose of this study is to analyze the doctors' attitude of those ethical issues and emphasize the importance of hospice. Methods : During September 1996, doctors who worked for a university hospital participated in this study by responding to the pre-made questionnaire. It dealt with the most suffering pain, the preferred death place, the use of life maintaining equipments, the application of cardiopulmonary resuscitation(CPR) to terminal patients and the doctors' experience and attitude euthanasia. Results : ① The most suffering symptom in dying patients was pain(60.0%). ② The death place was recommended by doctors was home(58.8%) and hospital (15.4%) in order. ③ 56.9% of doctors answered 'the life maintaining equipments isn't needed', 29.2% of doctors answered' according to the case', and 'needed' was 12.3%. ④ The application of CPR to the terminal patients, without the DNR chart, the only 15.4% of doctors answered "Do not CPR." But with the DNR chart, the percents of 'Do not CPR' was increased to 69.2%. The resident group did more CPR than specialist group(p<0.01). ⑤ The 50.8% of doctors agreed with the passive euthanasia. Conclusions : Many doctors follow the family member's opinion in the ethical issues of the dying patients. Euthanasia is forbidden by the law in Korea, but many doctors agree with the passive euthanasia. Hospice can solve the debating ethical issues including the euthanasia.

In this report, the authors analyzed retrospectively 20 cases of pure traumatic basal ganglia hemorrhage(TBGH) which were diagnosed and treated in our hospital between January 1990 and Jun 1995. The TBGH incidence constitutes 1.4% of all head trauma. It occures were commonly among the younger male patient groups. The main causes of trauma was motor vehicle accidents. The overall mortality rate was 15%. Low initial GCS score, fixed pupillary reflex, pathologic reflex, poor motor response and large hematoma size were all poor prognostic factors, resulting a high mortality or passimistic outcome.

鄭然郁,嚴基善,林漢鍾 고려대학교 의과대학 1985 고려대 의대 잡지 Vol.22 No.3

Comparative studies were performed for Capillaric hepatica antibodies with following immunodiagnostic assays : circumoval precipitation reaction(COP) with lyophilized eggs as antigen, indirect fluorescent antibody test (IFAT) with sectioned egg antigen, enzyme-linked immunosorbent assay(ELISA) with soluble egg antigen and counterimmunoelectrophoresis (CIEP) with soluble egg antigen. In the first part of this study it was found that every type of egg antigens used were effective and showed almost equal sensitivities with proper immunodiagnostic methods. Additionally, antibodies to C. hepatica were detectable only during short period after experimental infection of embryonated eggs. Sera from 40 white rats infected with 2,000 eggs orally were collected randomly between three and nine weeks after infection and the infection with C. hepatica was identified by necropsy. COP, ELISA & CIEP had diagnostic sensitivities of 85.0% and IFAT, 82.5 %. Sera from 5 white rats infected with 2,000 eggs were collected periodically to observe the changing patterns of antibody titers by IFAT and ELISA, which showed that high titers were detected at weeks 3 and 5, then gradually declined through weeks 9 until to negatively converted at weeks 13. The immunodiagnostic method of choice was recommended as ELISA since the antibodies were detectable with lowest protein contents(1.25 ㎍/ml) of antigen and highest dilution of sera (1 : 3,000), even though the equal sensitivity with other methods by different antigen and antibody conditions.
