Microorganisms were isolated and identified from bovine 296 quarters which showed positive reaction by California Mastitis Test (CMT) in 40 farms of Jeju from September 1999 to June 2000. The organisms associated with the mastitis of bovine were 11 different bacterial species in this study. Which of them, Staphylococcus aureus was the most predominant species as 152 (51.4%) isolates. Other identified species included 49 (16.5%) coliform, 47 (15.8%) Streptococcus dysgalactiae, 15 (5.1%) Bacillus spp., 8 (2.7%) Staphylococcus epidermidis, 6 (2.1%) Streptococcus agalactiae, 5 (1.7%) Enterococcus faecalis, 5 (1.7%) Corynebacterium spp., 3 (1.0%) Streptococcus uberis, 1 (0.3%) Pseudomonas aeruginosa and 1 (0.3%) Pasteurella haemolytica. Almost of all the islolated beacterial species showed high sensitivity against kanamycin (98.6%), cephalothin (98.0%), streptomycin (94.9%), gentamicin (94.6%), ampicillin (92.2%) and polymyxin B (90.2%). On the contrary, they showed resistance against penicillin (47.0%), tetracycline (37.2%), cefazolin (26.0%), bacitracin (22.6%) and erythromycin (19.9%). Eighty-one isolates were not resistant to any antibiotics and 215 drug resistant isolates showed 89 different drug resistance patterns from single to nine multiple antibiotics resistance patterns.

Objectives : We analyzed the changes from 1996 to 2002 in distributive equity of the contribution burden in the Korean National Health Insurance. Methods : The study subjects were a total of 8,923 employee households and a total of 7,296 self-employed households over the period from 1996 to 2002. Those were the households meeting the two criteria as completing each annual survey and having no change in the job of head of the household during that period from the raw data of the Household Income and Expenditure Survey annually conducted by the Korean National Statistical Office. The unit of analysis was a household, and this was the standard for assessing the contribution that is now applied on a monthly basis. Deciles Distribution Ratio, Contribution Concentration Curve and Contribution Concentration Index were estimated as the index of inequality. Multiple regression analysis was conducted to compare the annual ability-to-pay elasticity of the contribution to the reference year of 1996 for three groups (all households, the employee households, and the self-employed households). Results : For the index of inequality, the distributive equity of contribution was improved in all three groups. In particular, the employee group experienced a substantial improvement. Using multiple regression analysis, the ability-to-pay elasticity of the contribution in the employee group significantly increased ($\beta$=0.232, p<0.0001) in the year 2002 as compared to the reference year of 1996. The elasticity in the self-employed group also significantly increased ($\beta$=0.186, p<0.05), although its change was smaller than that in the employee group. Conclusions : The employee group had a greater improvement for the distributive equity of the contribution burden than the self-employed group. Within the observation period, there were two important integration reforms: one was the integration of 227 self-employed societies in 1998 and the other was the integration of 139 employee societies in 2000. We expected that the equity of the contribution burden would be improved for the self-employed group since the integration reform of 1998. However, it was not improved for the self-employed group until the year 2000. This result suggests that capturing exactly the beneficiaries' ability-to-pay such as income is the precedent for distributive equity of the contribution burden, although a more sophisticated imposition standard of contribution is needed.

목적 : 전이성 뇌종양은 성인 악성 종양환자의 흔한 합병증이다. 저자 등은 전이성 뇌종양의 임상적인 특징, 치료 효과, 생존에 영향을 미치는 예후 인자를 알아보고자 하였다. 대상 및 방법 : 1991년 1월부터 1997년 12월까지 본원에서 전이성 뇌종양으로 진단 받은 97예의 환자를 대상으로 하여 후향적으로 분석하였다. 결과 : 뇌전이의 원발종양으로는 폐암 (61예, 63%)이 가장 흔하였으며 그 외 원발 불명 전이성 뇌암 (15예, 16%), 위장관암 (13예, 13%), 유방암 (6예, 6%), 신장암 (2예, 2%) 순이었다. 단일성 뇌전이는 44예 (45%)였으며 다발성 뇌전이는 53예 (55%)였다. 치료 유무 및 종류를 고려하지 않을 경우 중앙생존기간은 3개월이었으며 1년 생존율은 8%였다. 생존율에 영향을 미치는 유의한 예후인자로는 진단당시 활동능과 신경손상의 정도 (p< 0.01)였다. 어떠한 치료도 시행하지 않는 군에 비해 스테로이드를 포함한 치료를 시행한 군에서 유의한 생존기간의 증가를 관찰할 수 있었다 (1.1개월 대 3.7개월). 스테로이드 단독 치료에 비해 전뇌 방사선 조사를 추가한 군에서 유의하게 생존기간이 연장되었다 (2.2개월 대 4.8개월). 추가적인 항암화학요법은 유의한 생존기간의 향상을 가져오지는 못하였다. 수술적 절제술을 시행한 군의 중앙생존기간은 8.8개월로 스테로이드와 전뇌 방사선치료만 시행한 군에 비해 유의한 생존기간의 증가를 보였다. 결론 : 전이성 뇌종양 환자에서 전뇌 방사선치료와 스테로이드는 유용한 완화치료 방법이며 진단 당시 활동능과 신경손상의 정도가 중요한 예후 인자로 분석되었다. 후향적인 연구로 인해 결과 해석에 한계가 있으나 수술적 절제 및 항암화학요법이 일부 선택된 환자 치료시 중요한 수단이 될 것으로 사료된다. Background : Brain metastasis is a common complication in cancer patients. We evaluated the clinical characteristics, treatment outcome and prognostic factors for patients with metastatic brain tumor. Methods : The records of 97 patients with metastatic brain tumor during the period from January 1991 to November 1997 were reviewed retrospectively. Results : The most common primary tumor is lung cancer (61 cases, 63%) followed by metastatic cancer unknown primary site (15 cases, 16%), gastrointestinal cancer (13 cases, 13%), breast cancer (6 cases, 6%) and renal cancer (2 cases, 2%). There were 44 patients with a single brain metastasis and 53 patients with multiple brain metastases. The median survival was 3.0 months and one-year survival rate was 8% irrespective of treatment. Favorable prognostic factors which affect survival were ambulatory status (p<0.01) and functional neurologic class 1, 2 (p<0.01). Median survival was 3.7 months for patients with steroid therapy and 1.1 months with no therapy (p<0.01). Median survival was 4.8 months for patients with steroid therapy plus whole brain radiotherapy (WBRT) and 2.2 months with steroid therapy alone (p<0.01). Additional chemotherapy did not appear to affect the survival. The patients treated with surgery had median survival time of 8.8 months compared with 2.5 months for patients treated with steroid therapy plus WBRT (p<0.05). Conclusion : In present study, we confirmed that whole brain irradiation and corticosteroid administration are effective palliative treatment for patients with metastatic brain tumor. Initial performance status and neurological function were identified as important prognostic factors. Although confounded by the limitations of retrospective study, more aggressive treatments including surgery and chemotherapy could be regarded to have a significant role to achieve better treatment outcome in some selected cases.(Korean J Med 62:444-452, 2002)
