Background : In recent years, gonorrhea has been pandemic and remains one of the most common STDs in the world, especially in developing countries. Objective & Methods : For the detection of a more effective therapeutic regimen and assessing the prevalence of PPNG, we have been trying to study the patients who have visited the Venereal Disease Clinic of Choong-Ku Public Health Center in Seoul since 1980 by means of the chromogenic cephalosporin method. Results : In 1997. 99 strains of N. gonorrhoeae were isolated, among which 45(45.5%) were PPNG. Conclusion : The prevalence of PPNG in Seoul, which had been decreased to 39% in 1996 after a peak of 74.3% in 1993, is increased to 45.5% in 1997.

Purpose: Endovascular repair is a alternative treatment with favorable short-term result, but long term results are not available compared to standard operation. The authors have reviewed experiences of Asan Medical Center on stented graft, performed from Aug. 1998 to Feb. 2000, and the results as to age, operative indication, clinical condition, anatomic location, complication, follow-up are reported. Method: Seven patients who has received stented graft between Aug. 1998 and Feb. 2000 are reviewed retrospectively. Result: Of the seven patients, 6 were male and 1 was female. The mean age was 46.4 years (17~71). Indication for stented graft were two pseudoaneurysms, two iatrogenic arterio-venous fistulas, one thoracic aorta aneurysm, one abdominal aortic aneurysm, and one iliac artery occlusion with blue toe syndrome. Three different types of stented graft devices were utilized: Dacron-covered nitinol stented graft (made by the Asan Medical Center medical device team), Vanguard II (by Boston Scientific Corp.), and PTFE with nitinol stented graft (by Tae-woong). There was no perioperative mortality, and the technical success was achieved in five cases (71%). The patency at 14-month were 1009o (5/5). Two immediate complications are hemorrhage due to iliac & femoral artery avulsion requiring emergency bypass grafting, and deployment failure of stented graft requiring removal of retained graft device. Conclusion: Stented graft may be utilized even in complicated vascular situation but will need further development of device and more experience to prevent possible catastrophic complication. Indication should be decided by team approach and vascular surgeon should be prevent or participate during the procedure.

This study was designed to compare segmental body composition and bone mineral density in spinal cord-injured(SCIS; n=9, SCIA; n=9) and non-injured control(AB; n=9) subjects. Dual-energy X-ray absorptiometry(DEXA) was used to measure %body fat, body fat mass, lean body mass, bone mineral contents, and bone mineral density in total and various body regions(arms, legs, trunk). The present results showed that body fat mass and %body fat were significantly higher and lean body mass was significantly lower in the SCIS group compared to AB group, while there was no difference between the SCIA and AB group in those of parameters. In BMC, there was no difference among groups and in BMD, SCI group was significantly lower that AB group, but there was no difference between SCIA group and AB group. Based on these results, in can be suggested that long-term regular exercise can reduce the negative changes in body composition, bone mineral density by spinal cord injury.

Rheumatoid arthritis, fibromyalgia, and spondylarthritis are important diseases causing chronic pain and disability in rheumatologic areas. The classification and diagnostic criterias of them were made on the basis of clinical features, radiologic and laboratory findings and have been used decades ago. According to the development of new knowledge about etiology and pathogenesis of rheumatic diseases, the need for new criteria has been increased. In recent years, new criteria for these diseases have been developed, and they allow the early assignment of diseases and early start of therapy. In this review, the author summarizes recent advances and changes in diagnosis of rheumatoid arthritis, fibromyalgia, and spondylarthritis.

Monascus anka로부터 유기배양에 의한 적색소의 대량생산

김희구,박근태,손홍주 한국식품영양학회 1998 韓國食品營養學會誌 Vol.11 No.6

Monascus anka KFCC 4478의 적색소 생산력을 증가시키기 위하여 발효조 배양조건을 검토한 후, 탄소원을 연속적 또는 간헐적으로 공급하는 유기배양을 하였다. 5l 용량의 발효조를 이용하여 배양시 교반속도 200rpm, 통기량 1vvm 및 종균 접종량 10%(v/v)일 때 색소 생성량이 최대였다. 또한 벽면에 부착된 균사체를 재접종함으로써 색소 생성력이 향상되었다. Intermittent feeding fed-batch culture에 의하여 배양 9일만에 30g/l의 건조균체와 350(A_495)의 색소가 생성되었으며, continuous feeding fed-batch culture에 의하여 22g/l의 건조균체와 190(A_495)의 색소가 얻어졌다. 따라서 본 균주에 의하여 적색소를 생산코자 할 경우는 회분배양보다 유기배양이 더 우수한 것으로 나타났다. The production of red pigment from glucose by fed-batch culture of Monascus anka was investigated. In batch culture using fermentor, 200 rpm of agitation speed, 1vvm of aeration volume, and 10%(v/v) of inoculum size were optimal, respectively. The red pigment production was increased by removal of wall-attached mycelium. In an intermittent feeding fed-batch culture, dry cell weight increased to 30g/l, and the red pigment content reached 350 of absorbance at 495nm. In a continuous feeding fed-batch culture, dry cell weight increased to 22g/l, and the red pigment content reached 190 of absorbance at 495nm.

Streptococcus mutans의 치태형성에 대한 Leuconostoc lactis 51의 영향

김태근,양규호,오정석 전남대학교 치과대학 2000 전남치대논문집 Vol.12 No.1

Dental caries is a bacterial disease of the dental hard tisssus, characterized by a localized, progressive, molecular disintegration of tooth structure. The action of Leuconostoc lactis 51 about plaque formation and replication by Streptococcus mutans was studied as follows. 1. Lower amount of plaque was produced at the mixed culture of S. mutans and L. lactis 51 than S. mutans alone on the wires in the beaker. 2. Fewer cells of S. mutans were replicated at the mixed culture of S. mutans and L. lactis 51 than S. mutans alone. 3. In M17Y broth, viable cells of S. mutans and L. lactis 51 increased for 12 hours, and decreased for 24 hours. In M17YS broth, viable cells of S. mutans showed time-dependent decrease at mixed culture of S. mutans and L. lactis 51. 4. The culture supernatant of L. lactis 51 didn't inhibit the replication of S. mutans and the formation of artificial plaque. 5. Sucrose and frutose were extracted from the culture supernatant of L. lactis 51 in M17YS broth. These results suggest that L. lactis 51 isolated from the oral cavity inhibits the replication of S. mutans and the formation of artificial plaque.

경상남도 양산천 일대의 토양시료로 부터 toluene을 유일한 탄소원 및 에너지원으로 생육하는 미생물들을 분리하였고, 그 중 toluene의 분해능이 가장 우수한 균주를 선별하여 공시균으로 선택하였다. 공시균의 형태학적, 배양적, 생화학적 및 화학분류학적 제반 특성들을 토대로 분류학적 위치를 검토한 결과 Rhodococcus 속으로 동정되어 편의상 Rhodococcus sp. EL-43P로 명명하였다. Rhodococcus sp. EL-43P는 phenol 및 다양한 phenol 유도체, benzene 등의 방향족화합물 기질에서 생육할 수 있었다. 특히 phenol 분해에 관련된 각종 환경조건을 최적화시키면 실제의 phenol 함유 폐수처리공정에서 충분히 적용가능성이 있음을 알 수 있었다. Rhodococcus sp. EL-43P는 catechol 1,2-dioxygenase의 활성을 가지고 있어 ortho pathway에 의하여 phenol을 분해함을 알 수 있었다. 또한 본 공시균은 toluene dioxygenase의 활성도 가지고 있었다. The microorganisms which degrade toluene as the sole and energy source were isolated from soil around Yangsan river. Among them, the strain EL-43P had the highest toluene degradability and identified as a Rhodococcus sp. according to morphological, cultural, biochemical and chemotaxonomical properties. Rhodococcus sp. EL-43P was able to grow at the various chlorinated phenols such as o-, p-chlorophenol, 2,3-,2,5-, 2,6- and 3,4-dichlorophenol, and benzene, respectively. If detailed phenol degradation conditions are established, the treatment of phenol wastewater using Rhodococcus sp. EL-43P would be possible. Rhodococcus sp. EL-43P had the catechol 1,2-dioxygenase which degrades Phenol derivatives by ortho pathway. This strain also had toluene dioxygenase.
