배경: 삼첨판막친환술은 매우 드물게 시행되는 수술이며 그 장기 성적은 만족치 못한 수준이다. 또한 어떤 종류의 인공판막을 사용하느냐에 대하여도 논란이 많은 상황이다. 서울대학교병원 흉부외과에서는 1989년 1월부터 1998년 12월까지 10년동안 71명의 환자에서 72례의 삼첨판막 치환술을 시행하였으며 이 결과를 토대로 장단기 성적과 위험요인들을 분석하였다. 대상 및 방법: 평균나이는 42$\pm$13세(16~65세)였으며 남여비는 32/39였다. 술전진단은 50례의 후천성판막질환과 18례의 선천성심장질환이 있었고 삼첨판폐쇄부전만 단독으로 있었던 경우도 4례 있었다. 사용된 인공판막은 기계판막이 69개, 조직판막이 3개였다. 승모판막치환술 또는 대동맥판막치환술과 같이 시행된 경우는 50례였고 1례에서는 폐동맥판막 치환술이 같이 시행되었다. 결과: 조기사망은 7례(9.7%), 만기사망은 7례(13.0%)였고 10년 생존율은 59.2$\pm$7.2%였다. 삼천판막혈전증은 5례에서 11번에 결쳐 발생하였으며 그중 1례는 재수술을 시행받았다. 생존자들의 대부분은 심장기능분류 I-II의 상태로 현재까지 외래 추적관찰중이다. 결론: 삼첨판막치환술은 비록 혈전증등의 위험이 상존하기는 하지만 비교적 낮은 사망률과 이환율을 보이고 있으며 기계판막의 경우에도 조직판막과 비교하여 큰 차이 없이 좋은 장기성적을 얻을 수 있었다. Background: Tricuspid valve replacement is very rarely performed procedure and its long-term result is not yet satisfactory. Moreover, it is not well known whether bioprosthesis or mechanical prosthesis is the best selection for artificial valve. We reviewed 72 cases of tricuspid valve replacements in 71 patients between January 1989 and December 1998, trying to analyze the overall results and risk factors for mortality and morbidity. Material and Method: Average age of the patients at the time of operation was 42$\pm$13 years(range 16 to 65 years) and the sex ratio of male versus female was 32/39. Primary diagnosis consisted of 50 cases of aquired valvular heart disease and 18 cases of congenital heart disease, such as Ebstein’s anomaly. 4 cases had isolated tricuspid valve regurgitation. Implanted valves were 69 mechanical prosthesis and 3 bioprosthesis. Concomitant mitral or aortic valve replacements were performed in 50 cases. One patient received concomittant pulmonary valve replacement. Result: There were 7(9.72%) operative deaths and 7(13.0%) late deaths. Actuarial survival at 10 years was 59.2$\pm$7.2%. Prosthetic tricuspid valve thrombosis occurred 11 times in 5 patients. Reoperation for prosthetic tricuspid valve failure was performed in 1 patient. In this case, examination of the explanted prostheses showed that the tricuspid stenosis was the result of valve thrombosis. Among the 47 survivors, 46 patients(98%) were in functional class I or II. Conclusion: In our ten-year experience of tricuspid valve replacement, mortality and morbidity were satisfactory. Mechanical prosthesis in tricuspid position showed comparable clinical results as bioprosthesis.

This study was aimed to evaluate the effect of oxygen on motor activity and toxicity in male mice. The modified Porsolt forced swim test (FST) was used and the distance and time of movement by mice were analyzed in 15℃ water bath for 20 minutes using the automatic Ethovision videotracking system. Analyses were carried out before and after 20 minutes of exposure to 10%-70% concentration of normobaric oxygen. The effects of inspired oxygen tension on the distance and time of movement showed the similar trends, but changes in distance were more prominent. Both the<br/> distance and time of movement increased after exposure to 30% and 40% oxygen concentration. The distance and time of movement also increased upon exposure to 50% and 60% oxygen. In contrast,<br/> increases in movement and time under exposure to 21% oxygen concentration were suppressed when exposed to over 50% oxygen concentration. With exposure to 10% oxygen, there was a significant<br/> decrease in the distance of movement and a slight suppression of movement time. During the swim test, 12.5%, 37.5%, and 87.5% of the mice drowned after exposure to 10%, 60%, and 70% oxygen concentration, respectively. These results suggest that motor activity can be enhanced by inspired oxygen up to 40% concentration. When hypoxic and hyperoxic oxygen exposure over 50%,<br/> motor activity is reduced and toxicity may be induced.

Kikuchi-Fujimoto disease (KFD), also known as histiocytic necrotizing lymphadenitis, is an uncommon idiopathic, self-limiting disease characterized by cervical lymphadenopathy. Patients with KFD may present with a wide variety of nonspecific symptoms, including fever, night sweats, and weight loss. Although KFD can affect all lymph nodes of the body, involvement of the intrathoracic lymph nodes is relatively rare. In particular, isolated involvement of the intrapulmonary lymph nodes is extremely unusual. We herein report a case involving a 45-year-old man who presented with symptoms of myalgia, fatigue, and fever. Computed tomography performed during follow-up showed a slowly growing nodule in the upper lobe of the left lung. Results of laboratory tests did not reveal any evidence of infection or autoimmune disease, including systemic lupus erythematosus. Results of excisional biopsy by video-assisted thoracoscopic surgery revealed KFD in an intrapulmonary lymph node. His symptoms improved after a trial of nonsteroidal anti-inflammatory drugs.
