Purpose: Although kidney is located in the retroperitoneal space laparoscopic radical nephrectomy is usually performed by the transperitoneal approach. At our institution the retroperitoneal approach is preferred. We evaluated the surgical outcomes, safety, oncologic outcomes, and compared with the results those of open radical nephrectomy in a contemporary cohort. Materials and Methods: Between January 2000 and December 2005 we performed retroperitoneal laparoscopic radical nephrectomy for renal cell carcinoma in 37 patients with clinical stage cT1 and cT2. Data from the these patients were retrospectively compaired with 30 contemporary cases treated with open radical nephrectomy. The clinical parameters including perioperative outcomes, complications, pathologic data, learning curve and recurrence were evaluated. Results: For the 37 retroperitoneal radical nephrectomies mean tumor size was 4.6cm (range 2.3 to 8.0), surgical time was 203.6min (range 110-410) and blood loss was 241.8cc. Mean specimen size was 10.4cm (8.7-14.4). Mean analgesic used day was 1.3 (0-4) and mean postoperative hospital stay was 4.2 days. minor complications occur in 16 cases and no major complications occurred. Surgical margins were negative for tumor in all patients. Variable parameters were comparable between patients undergoing laparoscopic and open radical nephrectomy. However, laparoscopy resulted in decreased blood loss, surgical times, analgesia use, time to oral intake, time to drain removal and postoperative hospital stay. No different complication rate is between two groups Conclusions: Retroperitoneal laparoscopic radical nephrectomy can be a safe and effective treatment in renal cell carcinoma. Although no long-term follow-up is available, our follow up to mean 31 months confirm the effectiveness of retroperitoneal laparoscopic radical nephrectomy in terms of surgical principles and oncological effectiveness.

The purpose of this study was to investigate and analyze effect of needle transcutaneous electrical nerve stimulation with the change of immunohistochemistry method through the change of c-fos in spinal dorsal horn(pre, 4, 8, 12 and 24h). An experimental arthritis induced in 100 Sprauge-Dawley rats with a mixture 3% carrageenan and 3% kaolin(0.1 ㎖ in sterile saline) into the joint cavity of one knee. Each group was randomly divided into four groups; Group Ⅰ : control group, Group Ⅱ : arthritic limb-induced group, Group Ⅲ : Needle TENS application on ipsilateral arthritic limb(2 Hz, 200 μs, 20 min) group, Group IV : Needle TENS application on contralateral arthritic limb(2 Hz, 200 μs, 20 min) group. The results of this study were as follows: 1. In naked eyes opinion, c-fos immunoreactive positive neurons are increased markedly 4 hours after arthritis limb-induced in Rexed Ⅰ, Ⅱ of superficial dorsal horn. Group Ⅲ and group Ⅳ are more decreased than Group Ⅱ at 8 hours after arthritis limb-induced. 2. The c-fos immunoreactive positive neurons after application needle like transcutaneous electrical nerve stimulation on arthritic limb-induced model group are more decreased than only arthritic limb-induced group. 3. The number of c-fos immunoreactive positive neurons in superficial dorsal horn was decreased markedly 4 hours after arthritis limb-induced. Group Ⅲ and group N are more decreased than Group Ⅱ at 8 hours after arthritis limb-induced(p<0.001). Specially Group Ⅲ showed the most significantly effect at 8 hours(p<0.01). The above results suggest that needle transcutaneous electrical nerve stimulation effectively reduced in arthritic limb-induced model. In addition, greatly decreased the number of c-fos neurons explains needle transcutaneous electrical nerve stimulation application on ipsilateral arthritic limb is more effective than that on contralateral arthritic limb.

Purpose : This preliminary study was done to identify sex related characteristics and sex knowledge of high school students. Methods : 622 high school students participated in the survey living in Gangreung city area. The data collection was done from May 1st to October 31st, 2000 using the self administered questionnaires. Results : The teachers and the peer students had a critical position in high school sex education. Reproductive physiology such as relations with the opposite sex, AIDS, STI, and contraceptions should be intensified in further sex education for high school students. There were sex differences in contraception and permission with sex relationship. And the false belief regarding sex assaults and knowledge deficit in AIDS were discovered. Conclusion : Sex education program development and application are necessary based on the educational needs and attitude evaluation for the sexual health improvement of high school students. In further study, developing the reliable measurement tool and various educational methodologies will be studied which are enough for the include the sex education concepts.
성견에서 교정적 고정원으로서의 티타늄 미니스크류에 대한 연구 : An experimental investigation in dogs

교정치료에서 원하는 치아이동을 위해서는 안정된 고정원이 필요한데 티타늄 미니스크류가 매식과 제거가 쉽고, 구강 내 여러 부위에서 적용이 가능하고, 환자가 느끼는 불편감이나 비용적인 부담이 적고, 제거 후에 치유가 빠르게 진행될 수 있는 등의 장점이 있어 최근에 교정적 고정원으로 사용되기 시작하였다. 티타늄 미니스크류를 교정적 고정원으로 사용한 임상 예들이 여러 편 발표되었는데 미니스크류의 이완이 가장 큰 실패의 원인으로 보고되고 있다. 그러나 지금까지 보고된 논문들에서 교정적 고정원으로 안정성을 줄 수 있는 스크류의 식립 길이에 관한 연구가 없는 상태이다. 교정적 고정원으로 미니스크류를 효과적으로 사용하기 위해서는 식립 부위에 따른 골구조와 골밀도 차이를 고려한 식립 길이에 관한 기준이 필요하다. 이에 본 연구에서는 성견의 상악골과 하악골에서 직경 2mm 티타늄 미니스크류를 다양한 길이로 식립하고 교정력을 적용한 후 그 안정성을 평가하여 교정적 고정원으로 사용될 수 있는 미니스크류의 식립 길이를 결정하고자 하였다. 미니스크류가 상악에서는 6mm이상, 하악에서는 4mm 이상이 골 내에 식립될 때 8주 동안 200g의 교정력에 동요도나 위치변화를 보이지 않았다. 식립 부위로는 부착치은 부위 치근 사이에 식립될 때 구강청결이 유지되고 미니스크류 주변 치은조직에 자극을 주지 않아 정상적인 조직으로 유지 될 수 있었다. 또한 교정력 적용 8주 후 치근단 방사선 사진검사에서 스크류 주변 치근 흡수나 치조골 흡수, 치주 인대 손상이 관찰되지 않았다. 따라서 상 ㆍ 하악 골밀도와 골구조의 차이를 고려하여 미니스크류의 골내 식립 길이를 적절히 조절함으로써 교정적 고정원으로 티타늄 미니스크류가 효과적으로 사용될 수 있다고 생각된다. Titanium miniscrews are being used increasingly as an anchorage for tooth movement, because they are easy to place and to remove, increase the number of sites available, give minimum strain to patients regarding surgical procedures, and offer uneventful healing after removal. The use of titanium miniscrews as an orthodontic anchorage has been reported in clinical case reports, but clinicians hove experienced screw loosening when using such screws. To our knowledge, there are no published reports evaluating the stability of miniscrews. Information about the length of miniscrews used in relation to the location is of some importance, as stability will vary depending on bone quality. The purpose of this study was to evaluate a variety of lengths of miniscrews (diameter: 2mm) which were inserted in maxilla or mandible and to demonstrate in a dog moedl which miniscrew provides fundamental stability in the jaws. 10 mm long miniscrews in the maxilla and 8mm long miniscrews in the mandible showed no clinical mobility and retained their position throughout an 8 weeks force (200g) application. The mucosal condition around the screws was healthy in cases in which miniscrews were inserted in the alveolar bone between the roots and the head of the screws emerged into the attached gingiva. When the force application was terminated, radiographic analysis revealed neither root resorption nor periodontal pathology around the miniscrews that remained stable during the entire treatment period. This study suggests that if titanium miniscrews with adequate length are properly used depending on the location, they provide sufficient stability for orthodontic anchorage.
