Stenosis of central vein is a common complication arising after percutaneous subclavian vein catheter insertion performed for temporary vascular access in chronic renal failure patients undergoing hemodialysis. There are several treatment methods for the condition like percutaneous angioplasty(PTA), stent insertion, and surgery, but recent trend is toward PTA and stents. Among the patients diagnosed with chronic renal failure from March 1993 to May 2002 and undergoing hemodialysis through AV fistula, the 14 Patients in whom central vein stenosis arose were selected for the study. A total of 28 percutaneous interventions(5 PTA and 23 stent placement) were performed, and restenosis rate and the time taken till the restenosis in de novo lesions and instant lesions were compared. All 28 cases were operated successfully. The 14 cases that received both anigioplasty and stent placement initially. (de novo lesion : 14 cases), Among the 10 cases with de novo lesion that followed up more than 1 year, 3 cases are currently undergoing hemodialysis without restenosis, and the remaining 7 cases have recurred stenosis with the mean time to restenosis of 10.9 months. In the 7 cases in whom stenosis recurred, 11 interventions were done(instent lesion: 11 cases). 4 of these were using only ballon angioplasty with 100% restenosis rate and the mean time of 3 months until restenosis. The remaining 7 cases were using both balloon angioplasty and stent placement, also with 100% restenosis rate but with the mean time of 12 months until restenosis, which was later than the group receiving only balloon angioplasty. In treating the patients with central vein stenosis, stent placement seems to be more advantageous over PTA in terms of restenosis rate and the mean duration of patency. In the case of instent lesion, inserting the stent for the second time after stenosis recurred lengthened the duration of patency compared to performing balloon angioplasty alone.

These results were analyzed aerobic capacity power and blood lactate concentration of before and after exercise with Rhythmic Sportive Gymnastic Player. These were measured respiratory gas analysis blood lactate concentration by gradual increment treadmill exercise test to all out with rhythmic sportive gymnastics players (n = 7) and general female collegians (n = 8)in S-university. The results are summerized as follows: 1. The V˙ O_2max. ㎖/㎏ of rhythmic sportive gymnastics players appeared 51.98 ± 2.3 ㎖/㎏, according to gradual increment treadmill exercise method. But in case of general female collegians, the Vo max was calcurated 42.74 ± 3.11 ㎖/㎏. Two groups showed significant difference statistically(P<.001). 2. Anaerobic threshold levels showed that rhythmic sportive gymnastics players remained 34.83 ± 1.24 ㎖/㎏ and general female collegians were measured 29.41 ± 2.02㎖/㎏. Two groups appeared significant difference statistically(P<.001). 3. The maximum of blood lactate concentration showed that rhythmic sportive gymnastics players were calibrated 9.08 ± 2.19 mmoles/ ℓ and general female collegians were measured 8.05 ± 1.05 mmoles/ ℓ. Two groups seem to be different statistically(P<.05). 4. The blood lactate concentration recovery rate in 15-minute rest after achieving gradual increment treadmill exercise method to all out showed rhythmic sportive gymnastics players recovered faster than general female collegians did, as 37.14% and 23.44% respectively. Two groups appeared significant difference statistically(P<.001). According to these results, the critical contents in the time of training of rhythmic sportive gymnastics players are the exercise should be at the state which maximum blood lactate concentration accumulated over 9 mmoles and in addition, if we should study abreast with the field of anaerobic power afterwards, we would present lost of matterials for the future.

연구 배경 : 급성 신부전은 술 후 발생할 수 있는 합병증 중에서 사망률은 큰 영향을 줄 수 있으므로 이 연구를 통해 위험인자를 알아보려고 한다. 재료 및 방법 : 2004년 1월부터 2006년 12월까지 3년간 영남대학교 의과대학 부속병원에서 대장 수술을 받은 570명의 환자들을 대상으로 하였다. 환자들의 성별과 연령, 미국 마취과학회 신체등급, 동반질환, 수술의 종류, 응급수술의 여부, 수술 시간, 재수술의 여부, 술 중의 투약 상황, 술 후에 자가 통증 조절기에 사용한 약제, 술 중에 저혈압의 유무, 수혈 여부, 술 후 기계적 환기를 시행한 경우를 비교하였다. 결과 : 비교 결과에서 성별과 수술의 종류, 응급 수술의 여부, 개복여부 등에는 유의한 차이를 보이지 않았다. 반면 환자의 나이와 수술 시간, 재수술의 여부, 술중에 이뇨제 등을 사용한 경우, 술 중에 저혈압의 유무, 술 후에 기계적 환기를 시행한 경우 등에는 유의한 차이를 보였다. 결론 : 이상의 결과로 급성신부전의 원인은 어느 한 가지라고 하기 보다는 위험인자에 얼마나 노출되어 있는가가 결정하는 것 같고, 그 원인들이 모여서 상승효과를 내는 것 같다. 그러므로 수술 전부터 많은 위험에 노출된 환자는 술 중 더 적극적인 감시를 시행하여 수술 후의 합병증 발생을 줄이는 노력을 기울여야 하겠다. Background : Acute renal failure is one of the leading causes of postoperative morbidity and mortality. The purpose of this study was to determine the risk factors that are associated with acute renal failure after colorectal surgery. Materials and Methods : Five hundred seventy patients who operated colorectal surgery at the Yeungnam University Medical Center over three years from 2004 to 2006 were enrolled in this study. The effects of gender, age, ASA classification, concomitant disease, surgery type and duration, reoperation, urogenital manipulation, medication, hypotension, hypovolemia, transfusion, and postoperative ventilatory care on the occurrence of acute renal failure after colorectal surgery were studied. Results : The major risk factors of acute renal failure after colorectal surgery were age of patients (P=0.003), ASA classification (P<0.001), concomitant disease (P<0.001), duration of the time surgery (P=0.034), reoperation (P=0.001), use of intraoperative diuretics (P=0.005), use of postoperative diuretics (P<0.001), intraoperative hypotension (P=0.018), intraoperative transfusion (P<0.001), postoperative transfusion (P<0.001), and postoperative ventilatory care (P=0.001). Conclusion : Multiple factors cause synergistic effects on the development of acute renal failure after colorectal surgery. Therefore, efforts to reduce the risk factors associated with acute renal failure are needed. In addition, intensive postoperative care should be provided to all patients.

한국에서 절멸된 것으로 알려진 종어 (Leiocassis longifostris)를 국내에 복원하고, 양식대상종으로 개발하기 위하여 중국에서 도입하여 외부형태를 비교하고, 난발생 과정 및 부화자어의 형태를 연구하였다. 도입된 표본의 계수·계측형질을 국내와 중국에 알려진 문헌과 비교한 결과 큰 차이를 보이지 않았다. 중국에서 도입한 암수 한쌍의 성어에서 채란하였고, 습식법으로 수정하였다. 수정란의 크기는 2.01∼2.10 mm(n=10)이었으며, 알의 형태는 원반형이고, 난막은 무색투명하였으며, 강한 접착력이 있었다. 난황은 담황색이고 유구는 없었다. 수정 1시간 후에 배반이 완성되었고, 1시간 30분 후에 난할이 시작되었다. 수정란의 수온을 21.5∼23.0℃로 유지할 때 30∼50분 간격으로 이후 난할이 계속되었다. 수정 후 상실기는 6시간에 도달하였고, 낭배기는 20시간 20분 후에 완성되었다. 난황 표면에서 관찰되는 특이한 연동운동은 상실기에 시작되어 포배기 말기인 30% epiboly기까지 계속되었다. 수정 75시간 후에 부화에 이르렀고, 부화 직후 자어의 크기는 전장 5.91∼6.10 mm 이었다. 부화 3일 후에 입이 열리고, 수염과 부레가 완성되었으며, 전장 9.07 ∼9.37 mm까지 자랐다. 부화 15일후에는 모든 지느러미가 완성되어 후기자어기 상태이었고, 전장 14.80∼16.50 mm로 자랐으며, 부화 25일 후에는 체형, 체색 그리고 생활습성 등이 성체와 유사하고, 전장은 18.59∼22.35 mm까지 성장하였다. The Long-snout bullhead, Leiocassis longirostris, is an introduced fish from China which had become extinct in Korea. Its morphological characteristics and early life history was studied to obtain useful information required for restoration of the species and also for its utilization as an aquaculture fish. Measurements and counts of specimens introduced into Korea were included in the range of those taken from the known literature of Korea and China. Eggs were obtained by fertilization by wet method in the laboratory using one mature male and female adults of introduced L. longirostris. The fertilized eggs measured 2.01-2.10 ㎜ (n = 10) in diameter. The eggs were diskshaped and strongly adhesive, with colorless transparent membrane. The yolk was pale yellow in color with no oil globule. The blastodisc was formed in about 1 hour and cleavage started around 1 hour 30 minutes after fertilization. The cleavage intervals were about 30-50 minutes at 21.5-23℃. The morula stage was reached at 6 hours, and gastrulation was completed at 20 hours 20 min. after fertilization. Peristalsic movements of the yolk surface started at the morula stage and continued to the blastula stage (30% epiboly). Hatching occurred 75 hours after fertilization, and newly hatched larvae were 5.91-6.10 ㎜ (n = 10) in total length (TL). The mouth was open, and barbels and the air-bladder were completely formed 3 days after hatching, at 9.07-9.37 ㎜ TL. All the fin rays were completely formed and the larvae became a postlarva 15 days after hatching at 14.80-16.50 ㎜ in TL. Body shape, color pattern, and habitat behavior were similar to those in the adult at 25 days after hatching and a size of 18.59-22.35 ㎜ TL.

To evaluate the status of the contact to lascivious computer programs and sexual attitude and behaviour by the grades of middle school boy students, the questionnaire survey was done on 715 students of five middle schools in Pusan and Kimhae area from December 15 to December 24, 1997. The data were analyzed by PC SAS; X² -test. The level of significance was 0.05. 404 students (56.5%) had a personal computer in their home. 516 students (72.2%) have experienced of using a computer program. 294(57%) of them usually played a game with computer. 514 students(71.9%) had experiences of the contact to a lascivious computer program, which increased with the grades of the students(p〈0.05). The first exposure to a lascivious program was when they were elementary school students in 24.6% of first grade middle school students, 13.8% of second grade, and 11.3% of 3rd grade students. 92% of the students was introduced to first contact through their friends. 63.7% of them watch the program at their friends home. The most common drives to contact to a lascivious programs were curiosity (53%). Sexual desire was a higher drive in third grade students (20.6%) than lower grades. After contacting to a computer lascivious program, desire of masterbation was more frequent in lower grade students, and feeling disgust was more frequent in higher grade students (p〈0.05). Frequence of masterbation or sexual intercourse was higher in high grade students(p〈0.05). In conclusion, distribution and popular use of computer attributes to the increased exposure to lascivious programs and lowering the age of first exposure. there was the difference according to the grades in the feeling and sexual behaviour after contacting to computer lascivious program. Appropriate methods to protect young students to contact a lascivious program should be sought. The use of computer should be educated in elementary school students accompanied by proper sex education.
