본 연구는 남자 대학생 유도선수들의 체급별 ACTN-3 유전자 다형성의 분포 특성과 유·무산소성 파워와의 관련성을 규명하여 선수들의 경기력 향상을 위한 기초자료를 제공하는 데 목적이 있다. 연구 대상은 Y대학교 남자 유도선수 60kg급 5명, 66kg급 8명, 73kg급 11명, 81kg급 10명, 91kg급 8명, 100kg급 7명 합계 49명을 대상으로 하였으며, ACTN-3 유전자 다형성은 공복시 혈액으로, 유산소 파워는 Bruce 방법을 이용한 점증부하 법으로, 무산소 파워는 Wingate 방법으로, DEXA로는 근육량과 체지방량을 분석하였으며, 이들의 특성과 유, 무산소성 파워 변인과의 관련성을 분석한 결과 다음과 같은 결론을 얻었다. 남자 유도선수들의 ACTN-3 유전자 다형성은 체급별로 볼 때 60kg은 RX>XX>RR, 66kg은 RX>RR, 73kg은 RX>RR=XX, 81kg은 RX>RR>XX, 90kg은 RX>RR=XX, 100kg은 RR>RX 순으로 각각 나타났으며, 대립유전자 간에도 R형이 X형보다 높은 것으로 나타났다. ACTN-3 유전자 다형성과 유산소 파워 및 무산소 파워 변인간에는 모두 유의한 차이가 나타나지 않았으나 유, 무산소성 파워 변인과의 상관성은 유산소성 파워변인의 경우 근육량과 지방량 모두 XX형에서 최대산소섭취량 간에 역 상관이, 무산소 파워변인의 경우 체중당 피크파워와 평균파워에서 모두 높은 상관성이 나타났다. 이상의 결과를 미루어 볼 때 유도선수들의 체급별 ACTN-3 유전자 다형성은 90kg 이하에서는 RX가 가장 많았지만 100kg급에서는 RR이 가장 많게 나타나 체급에 영향이 있는 것으로 생각된다. 또한 유산소 파워는 최대산소섭취량과 역 상관이, 무산소 파워는 체중 당 피크파워와 평균파워에서 근육량과 지방량 모두 상관성이 높은 것으로 나타났다. 그러나 유전자 다형성과 유, 무산소 파워와는 관련성이 낮은 것으로 생각된다. Purpose: The purpose of this study is to investigate the distribution characteristics of ACTN-3 gene polymorphism and relationships among the ACTN-3 gene polymorphism, aerobic and anaerobic power by weight categories in college-aged male judo athletes. total 49 college-aged male judo athletes in Y University were participated in this study and they were consist of various weight categories(60kg(n=5), 66kg(n=8), 73kg(n=11), 81kg(n=10), 90kg(n=8), 100kg(n=7). Fasted blood was obtained for analyzing ACTN-3, aerobic capacity was measured by VO2max test with bruce protocol, anaerobic power was determined by wingate test, body composition was measured by DEXA. The results in this study were shown as follows: 1. The ACTN-3 gene characteristics were shown with 60kg RX>XX>RR, 66kg RX>RR, 73kg RX>RR=XX, 81kg RX>RR>XX, 90kg RX>RR=XX, 100kg RR>RX according to each weight categories in male Judo athletes. 2. There are no significant differences among the ACTN-3 gene characteristics of aerobic and anaerobic performance. The above results, although there is no significant difference among ACTN-3 gene polymorphism and aerobic and anaerobic power, we observed that in the case of aerobic power FFM and Fat have inverse correlation for VO2max in types of XX and in the case of anaerobic power FFM and Fat have high correlation for peak power and mean power in type of RX and XX.

One of the current treatment methods for chronic osteomyelitis is removal of the infected and necrotic tissue to reduce the bacterial concentration as much as possible. This is performed concomitantly with antibiotic therapy. Chronic osteomyelitis(C.O.) implies chronic ischemia of the diseased bone. Thus, the treatment for C.O. requires high systemic level of antibiotics. In some cases, however, inherent undesirable adverse effects(for example, nephrotoxicity, ototoxicity, and others) may render this course of treatment difficult. Knowing that residual monomers are released from hardened bone cement, installation of antibiotic-impregnated PMMA(polymethylmethacrylate) beads in situ have been one of treatment methods of C.O. When introduced into the wound, they established an exceedingly high level of local antibiotics for prolonged period without high systemic level of antibiotics. We experienced favorable results with vancomycin-impregnated PMMA beads for the treatment of C.O. of the mandible. So, we report it with literature reviews.

Ectropion is a drooping or eversion of the lower eyelid as a result of lower lid laxity, canthal tendon laxity, or cicatrix formation from scarring. Ectropion can also be congenital or develop with aging. This complication can arise from primary trauma to the lower lid apparatus or as a result of unfavorable healing and scar contracture. To prevent development of ectropion, a careful attention in case of operation for orbital frature repair or blepharoplasty is necessary. Especially, excessive dissection or retraction of skin and orbicularis muscle should be avoided, and formation of edema and hematoma should be prevented by complete hemostasis. It might be helpful to massage on the eyelid frequently. In spite of endeavors mentioned above, lareral canthoplasty or skin graft must be performed when postoperative ectropion is occurred. With literature review the authors present a case report that good clinical result is achieved by lateral tarsal strip procedure on cicatricial ectropion caused by a complication of reconstruction of blow-out fracture.
