Some tricuspid valve endocarditis can be controlled effectively with specific antibiotic treatment. However, surgical intervention Is necessary when there are continuing sepsis, moderate or severe heart failure, multiple pulmonary emboli, and echocardiographycally demonstrated vegitations. We are repoting a 19 year-old male patient who was admitted for the treatment of infective endocarditis. He previously had an operation for ventriculer septal defect (perimembranous type) about 9 years ago . An echocardiogram showed a large vegetation on the anterior cusp area and a left to right shunt through VSD, which was previously closed with dacron patch. A valve replacement in addition to antibiotic therapy was recommended for the patient. The patient underwent on operation : tricuspid valve replacement was done with 51. Jude medical valve prosthesis (33 mm), and in addition to above procedure, removal of vegetation and direct closure of VSD were done Postoperative echocardiogram showed that replaced tricuspid valve functioned well and vegeta ion and shunt flow were not observed. The patient recovered without complication and discharged at Postoperative day 25. Early aggressive surgical intervention is indicated to optimize surgical results, and this case seems to be a typical right sided bacterial endocarditis, which is caused by residual VSD. We are reporting a case of tricuspid valve endocarditis with a review of the literature. (Korean J Thorax Cardiovasc Surg 1996 ; 29: 440-3)

Abundant amount of Chiamydia trachomatis could be amplified in mammalian McCoy cells and purified using descontinuous Uroarafin gradient centrifugation. As a chemical means io increase the Chlamydia trachomatis inclusions in McCoy cells IUdR treatment was found to be more effective than the cycloheximide treatment and was recommendanble for the proliferation of Chlamydia trachomatis. Centrifugation promoted Chlamydia trachomatis adhesion to McCoy cell surface, and maximal percentage of infected cells was obtained at about 3000g. The purified Chlamydia trachomatis could be kept in SPG solution for 48 hours at +4$^{\circ}C$ but for longer storage freezing to -7$0^{\circ}C$ was necessary.

Purpose: To describe the recent clinical results and complications of total elbow arthroplasty based on the literature review. Materials and Methods: The indications of total elbow arthroplasty include rheumatoid or inflammatory arthritis, posttraumatic arthritis, anklylosed elbow, tumor resection which cannot recover elbow function by other reconstructive procedures, and comminuted distal humerus fracture in elderly patients. Complications are aspetic loosening, infection, prosthesis fracture, periprosthetic fracture, ulnar neuropathy, ectopic ossification, triceps insufficiency, dislocation, and bushing wear. Results and Conclusion: Mean 10 year survival rate following total elbow arthroplasty has been reported 85% on the basis of revision. The prognosis in patients with an inflammatory arthritis is reported to be best, and loosening rate in patients with a posttraumatic arthritis tends to be high. Complication rate is known to be higher than that of other joint arthroplasty. In particular, deep infection occurs in 3~5% of the patients. Total elbow arthroplasty provide satisfactory results when it is performed properly in selected patients who have an elbow joint with irreversible dysfunction and low level activities.

본 연구는 운비요법(運脾療法)이 脾虛 동물모델 Rat의 흡수기능에 미치는 영향을 관찰하기 위한 것이다. 이혈평(利血平)으로 Rat의 비허(脾虛) 상태를 유발시킨 다음 최초로 비허(脾虛) 상태에서의 혈청 중 Zn 및 소장검막의 구조변화를 관찰하였고, 임상적으로는 소아의 편식증, 영양실조성 빈혈, 반복적인 소아감염증상(RRI) 등에 대한 운비법(運脾法)의 효과를 관찰하였다. 청결상태로 관리한 체중이 220-240g의 Wester계 웅성 Rat 15마리를 무작위로 각 5마리씩 정상군, 비허군(脾虛群), 중약투여군에 배분하여 3group으로 나누었다. 비허군과 중약투여군에는 모두 이혈평(利血平)을 소량으로 서서히 투여하였고, 중약투여군에는 동시에 중약 시럽(당장(糖漿))을 경구투여시켜 3주간 실험관찰하였다. 결과 : (1) 섭취량(g/일/마리) : 정상군은 22.1, 비허군(脾虛群)은 9.04, 중약투여군은 17.3으로 각각 나타났다. (2) 체중(g) : 정산군은 $284.2{\pm}32.51$, 비허군(脾虛群)은 $193{\pm}15.26$, 중약투여군은 $231.8{\pm}22.76$으로 각각 측정되었다. (3) 혈청 중 Zn함량(ug/1) : 정상군 $1911{\pm}993.8$, 비허군(脾虛群) $1094{\pm}249.4$, 중약투여군 $2599.8{\pm}1282.1$로 각각 측정되었다. 이와 같은 결과에서 중약투여군의 섭취량, 체중 및 혈청 중 Zn의 함량 모두 대조군에 비교하여 현저하게 개선되었음을 알 수 있다. (4) 소장의 정막구조 : 비허군(脾虛群)은 정상군에 비해 소장의 점막이 현저하게 얇고 융모상 돌기가 오그라들며 퇴화되는 변화를 나타냈고, 일부 융모상 돌기 끝의 상피세포는 국소적 괴사 및 퇴행성 변화를 일으키기도 하였다. 중약투여군은 이에 비해 소장점막이 거의 정상에 가깝게 회복되었다. 결론 : 운비요법(運脾療法)은 비허(脾虛) 동물모델에 대한 흡수기능의 개선에 효과가 있음을 본 실험에서 입증할 수 있었다.

Bovine viral diarrhea virus (BVDV) is an economically important worldwide disease in livestock industry. In this study, the occurrence of BVDV in Korean indigenous cattle was performed by RT-PCR using nasal swab. Twelve of 21 cattle were identified as BVDV positive and classified as persistently infected (PI). These animals showed the occurrence of diseases such as diarrhea and pneumonia. BVDV PI outbreaks were found mostly in PI calves. Sequencing and phylogenetic analysis based on the 5'-untranslated region (UTR) showed that our case belonged to BVDV-2a. These results suggested that the nasal swab sampling was available method for the detection of PI animals, underscoring the need for BVDV control strategies in Korean indigenous cattle.

4231년 농림부산림국에서 송충구제책으로 경기도 임업시험장에서 인공배양한 No.7호균외 수종을 사용할 계획인바 비에 대한 임업시험장 시험보고에 의하면 핵균은 송충에 대하여 맹독성이지마는 잠아에 대하여서는 기독성이 경미하다는 보고 이였으므로 양잠가에 대한 의문을 풀기 위하여 송충 및 잠아에 대한 전염성의 강약을 비교 시험하여 그 독성정도를 구명코저 함. 1. 경기도 임업시험장 연구보고 제1호에 기재된 No.7 호균의 시험성적과 본시험성적과를 대조하면 그 이병률은 일정한 경향을 표시치 않으며 다소 상치된 결과이었다. 즉 별표에 의하면 송충은 72~100% 잠아에 있어서는 4289년도에 0~2% 4290년도이 0~20%였으나 본시험결과 (표 1,2,3)는 송충은 표준구에 6.6% 처리구에 13.3~20%이고 잠아는 5~50%의 이병률이였다. 따라서 송충에는 그 감염도가 높으며 잠아는 그 감염도자 낮다고하는 근거를 인정키 난하다. 2. 본시험에 공시된 접종균 No.7호균은 경기도 임업시험장에서 호칭하는 황황강균(Insarica farinosa)이 었으나 핵균 배양시에 이균이 침입된 관계인지는 모르나 본시험에서 폐사를 검정한 결과 백강균(Botrytis Bassiana)이였다. 따라서 No.7호균에 대한 순도가 의심되며 시험결과의 정확을 기할수가없었다. 3. 경기도 임업시험장연구보고 제1호에 접수된 양년간시검성적에 의하면 경화병균 28종중 가장 이병률이 낮다고하는 No.7호균이 본시험결과에서 잠아에 5~50%의 이병률을 나타내는것으로 보아 소위 경기도 임업시험장에서 순수분리한 균은 어느것이라도 송충에 접종하여 산지에 산포하면 그 균이 중간기생 (인교목, 직교목)을 통하여 야생화되어서 더욱 잠아에 대한 전염력을 강렬하게됨으로 양잠상 위험할것이다. 일본의 소산씨 문헌(경기도 임업시험장도서관)에 의하면 야생혼충에서 전염되는 경화병균의 독성은 잠아에 대하여 강력하다는 점과 $\ulcorner$잠업지조선$\lrcorner$제11호에 전라남도 원잠종제조소 강본태대랑씨의 시험성적(참고문헌)이 이를 여실히 입증하는 바이다.

Mushroom consumption causes changes in the immune system and gut microbiota via the actions of mushroom probiotic components. β-Glucan structure-related substances suppress secretion of inflammatory mediators, and induce macrophage activation, enhancing immunity and immune function. Substances other than directly useful components can be metabolized into short-chain fatty acids by gut microbiota. These short-chain fatty acids can then induce immunity, alleviating various diseases. Substances used to stimulate growth of health-promoting gut bacteria, thereby changing the gut microbiota community are defined to be probiotics. Probiotic altered intestinal microflora can prevent various types of bacterial infection from external sources, and can help to maintain immune system balance, thus preventing diseases. Research into beneficial components of Pleurotus eryngii, Lentinula edodes, Pleurotus ostreatus, Flammulina velutipes, Auricularia auricula-judae, and Agaricus bisporus, which are frequently consumed in Korea, changes in microbiota, changes in short-chain fatty acids, and correlations between consumption and health contribute to our understanding of the effects of dietary mushrooms on disease prevention and mitigation.

Medical institutions remodel existing hospital buildings rather than construct buildings to satisfy patient satisfaction and enhance competitiveness with other medical institutions. Medical institution remodeling is gradually increasing due to enhanced laws and systems to improve the quality of medical services and the level of patient safety. However, prior studies were discussed only within a limited range, including architectural elements, about medical institution remodeling. Therefore, this study aims to provide basic data to medical institutions planning future remodeling by examining the legal issues of medical institution remodeling in various ways. Medical institution remodeling extends the construction period due to restrictions on construction conditions, and causes damage such as noise and dust to patients. So it is necessary to prevent damage to patients in advance and to support appropriate remodeling of medical institutions. Therefore, it is necessary to prepare an Act on promotion of and support for remodeling of medical institutions. In addition, medical institutions should prepare a checklist for voluntary compliance with construction standards, preventive measures and post-improvement measures, and measures for infection and radiation exposure in hospitals.

Purpose : The purpose of this study was to examine the molecular epidemiology and genetic variability of adenovirus(Ad) serotypes Ad1, Ad2, and Ad5 over 14 years in Korea. Methods : A total of 382 adenoviral strains isolated from the nasopharyngeal aspirates of children with lower respiratory tract infections in Seoul, Korea from November 1990 to February 2003 were serotyped by neutralization assay with type-specific antisera. Viral DNAs were extracted from infected cell lysates by the modified Hirt procedure. Genome type(GT) was determined by DNA restriction analysis with 12 restriction enzymess(BamHI, BclI, BglI, BglII, BstEII, EcoRI, HindIII, HpaI, SalI, SmaI, XbaI, and XhoI). To evaluate the genetic relatedness, pairwise comigrating restriction fragments(PCRF) analysis was performed. Results : Of 382 strains, 33 strains(9%) were Ad1, 45 strains(12%) were Ad2, and 24 strains(6%) were Ad5. Eighteen GTs(Ad1p1-Ad1p7, Ad1a, Ad1b, Ad1b1-Ad1b3, Ad1c, Ad1d, Ad1e, Ad1e1, Ad1e2, Ad1f) among Ad1, 24(Ad2p1-Ad2p11, Ad2a, Ad2a1-Ad2a6, Ad2b, Ad2c, Ad2d, Ad2e, Ad2e1-Ad2e3) among Ad2, and 10(Ad5p1, Ad5p2, Ad5a, Ad5a1-Ad5a7) among Ad5 strains were identified. One or two strains of the vast majority of GTs were isolated during the study period while a few GTs were identified sporadically with more than 2 strains. It is notable that some GTs such as Ad1p5 and Ad5a1 appeared in cluster during a short period. In analysis of genetic relatedness, the degree of PCRFs(pairwise comigrating restriction fragments) for Ad1 varied from 79 to 99%, for Ad2, 82 to 99%, and for Ad5, 85 to 99%. Conclusion : This study established the comprehensive nomenclature systems of Ad1, Ad2, and Ad5. Diverse GTs identified in this study have crucial implications in the genomic diversity and epidemiological characteristics of Ad1, Ad2, and Ad5.
