본 연구는 치근첨부위의 급한 만곡을 가진 근관에서 엔진구동형 니켈-타이타늄기구를 이용해 근관 성형시 근관형태 변화에 대한 비교 연구를 함으로써 어떤 기구가 근관의 본래 형태를 잘 유지하는가를 구명하기 위하여 시행되었다. #15 finger spreader를 이용해 만곡된 근관의 주형을 형성하고 epoxy resin으로 모형 근관을 갖는 레진 블록 96개를 제작하였다. 모형 근관은 만곡의 반경이 0.5 mm, 3.0 mm.4.0 mm 및 6.0 mm를 가지며, 근관의 만곡도는 90도로 제작하였다. 엔진구동형 니켈-타이타늄 파일로 ProFile, ProTaper, Hero 642 그리고 K³를 사용하였으며 크라운다운법을 이용하여 제조회사의 지시에 따라 300 rpm으로 근관을 성형하였다. 시술 전·후사진을 디지털 카메라를 이용하여 촬영한 후, 이미지분석기를 이용하여 근관의 변화량을 측정하였다. 근관의 만곡을 따라서 치근첨 으로부터 1 mm 간격으로 계측점을 총 9부분을 설정하여 원래의 근관형태가 유지되는 정도를 측정하였다. 각 계측점에서 근관의 중심축의 변위량, 근관의 폭의 변화량을 측정하였다. 계측점에서 각 기구들간의 유의성은 Kruskal-Wallis 분석법을 이용하였고 기구간에 검정은 Mann-Whitney U-test분석법을 이용한 결과 급격히 만곡된 근관 성형시에 반경 1.5 mm의 만곡에서는 엔진구동형 니켈-타이타늄 파일을 사용시 주의를 요하며, 반경3.0 mm 이상의 만곡에서는 다른 엔진구동형 니켈-타이타눔 파일보다는 ProFile의 사용이 권고된다. The purpose of this study was to evaluate which type of Ni-Ti files are able to maintain canal configuration better in the simulated canal with abrupt curvature near it's apex. Ninety six simulated root canals were made in epoxy resin and #15 finger spreader was used as root canal templates. The simulated root canals were made with radius of curvature of 1.5 mm, 3.0 mm, 4.0 mm, 6.0 mm respectively and the angle of curvature of all simulated canals were adjusted to 90 degree. The simulated canals were instrumented by ProFile, ProTaper, Hero 642, and K³ at a 300 rpm using crown-down pressureless technique. Pre-instrumented and post-instrumented images were taken by digital camera and were superimposed with Adobe Photoshop 6.0 program. Images were compared by image analysis program. The changes of canal width at the inner and outer side of the canal curvature, canal transportation were measured at 9 measuring point with 1 mm interval. Statistical analysis among the types of Ni-Ti files was performed using Kruskal-Wallis test and Mann-Whitney U-test. The result was that ProFile maintain original canal configuration better than other engine driven Ni-Ti files in the canals above 3.0 mm radius of curvature, and in the 1.5 mm radius of curvature, most of Ni-Ti flies were deformed or separated during instrumentation.[J Kor Acad Cons Dent 30(4):303-311,2005]

In order to investigate the reinforcemental Effects of Acanthopanax Radicis Cortex about immunity and hematogenic action. The various immune responses were studied. The results were obtained as follows: 1. Positive cell was significantly increased at the 0.25 d r n P degree of density in the effect of CD4 about the spleen cell. 2. In the effect of IgG positive cell was significantly increased as comrared with the data of control only at the 0.25 mg/ml degree of density. 3. In the effect of Mac-1 positive cell was significantly increased in all treated degree of density. 4. In result of observing the change of WBC after Cyclophosphamide-processing the number of WBC was significantly increased in treated Group. 5. Measurement of RT-PCR in Hematopoietic stem cell TPO PCR products was increased as compared with medium at the 1 ㎛/ml degree of density. 6. In reinforcemental effect about Stem cell factor SCF PCR product was increased as compared with medium at the low degree of density. 7. In reinforcemental effect about IL-3 PCR product was increased as compared with medium at the low degree of density. 8. In reinforcemental effect about IL-6 PCR product was significantly increased as compared with all treated group. 9. Assay about positive cell in the spleen cell, the positive cell was significantly increased in CD4, CD19. 10. Created amount NO was treated group significantly increased all degree of density. 11. In promotional dissolution-effect, treated group was increased one and half times or twice all degree of density as compared with negative control. According to the above results, Acanthopanax Radicis Cortex increase coherence with T-cell by dint of activating CD of T-cell, presentate an antigen, activate IL-3, IL-6 which stimulate B-cell mading an antibody, activate IFN- y which appeal anti-viral activity by dint of activating macrophage, activate IgG which being made in B-cell neutralize Virus directly, increase immunity by means of promoting dissolution of Spleen cell which involve immune cell and strengthen hematogenic action by dint of activating TPO, SCF. Although Acanthopanax Radicis Cortex was used in retrogressional joint disease of deficiency syndrome by reinforcing Liver and Kidney, strengthening bones and sinews, because IFN- 7 which appeal anti-viral activity and IL-6 which almost appear in arthritis increased significantly, in future we should make an effort in looking into action of Acanthopanax Radicis Cortex about common cold by infection and arthritis of excess syndrome.

This study was conducted to find out the difference in the use of latissimus dorsi muscle and forearm muscles between skilled and unskilled people when performing pull-up. The subjects of the study were one skilled in the department of sports science at Soon-chun-hyang University, one unskilled person who had no problems with the musculoskeletal system over the past year, and a total of two people who could do pull-ups more than 20 times. A total of one experiment was conducted, and two tests were conducted. The electromyogram data of the light back and forearm muscles were compared using a wireless electromyogram measurement device (EMG). As a result of the study, first, when performing pull-up, the unskilled person performed the movement with the strength of the forearm muscle rather than the light back muscle compared to the skilled person. Second, when performing pull-up, the skilled person showed similar use of force in both pull-up movements, and for non-skilled people, the activity of the forearm muscle in the second movement was significantly increased.

수산화칼슘 처리된 Porphyromonas endodontalis Lipopolysaccharide가 다형핵백혈구의 IL-1과 TNF-α 생성에 미치는 영향에 관한 연구

박찬제,박동성,유현미,오태석,임성삼 大韓齒科保存學會 2002 Restorative Dentistry & Endodontics Vol.27 No.5

Bacterial lipopolysaccharide (LPS) plays a major role in stimulating the synthesis and release of the principal osteoclast-activating cytokines , namely, interleukin 1 and tumor necrosis factor-α from immune cells, Although monocytes/macrophages are the main producers of these cytokines, recent evidence has indicated that polymorphonuclear leukocytes (PMN) have the ability to release IL-1 and TNF-α. Calcium hydroxide has been shown to be an effective medicament in root canal infectionsm, reducing the microbial titre within the canal. It has been proposed that the therapeutic effect of Ca(OH)_2 may also be the result of direct inactivation of LPS. The purpose of this study was to investigate whether treatment of Porphyromanas endodonatalis LPS with calcium hydroxide alters its biological action as neasured by human PMN secretion of IL-1 and TNF-α, and it was compared with Escherichia coli LPS. P.endodonatalis ATCC 35406 was cultured in anaerobic condition, and LPS was extracted using the hot-phenol water extraction method and purified. Purchased E. coli LPS was also purified . 100 ㎍/ml of each LPS in pyrogen free water were incubated with 25mg/ml Ca(OH)_2 at 37℃ for 7 days. The supernatants were subjected to ultrafiltration. And the isolates were lyophilized and weighed. PMNs were obtained from peripheral blood by centrifugation layered over Lymphoprep. The cells were resuspended (4 × 10^6 cells/ml) in RPMI 1640 followed by treatment with various concentrations of LPS (0, 0.1, 1, 10㎍/ml) for 24 hours at 37℃ in 5% CO_2 incubator. The supernatants of cells were collected and the levels of IL-1α, IL-1β and TNF-α were measured by enzyme-linked immunosorbent assay. The results were as follows; 1. The levels of IL-1α, IL-1β, TNF-α from PMN treated with each LPS were significantly higher than those released from unstimulated PMN of the control group (p<0.05). 2. The levels of all three cytokines released from PMN stimulated with each calcium hydroxide treated LPS were significantly lower than those released from PMN stimulated with each untreated LPS (p<0.05). while they were not significantly different from those released from unstimulated PMN of the control group (p>0.05). 3. The levels of secretion or all three cytokines were affected in a dose-dependent manner in PMN stimulated with each LPS (p<0.05), but not in PMN stimulated with each calcium hydroxide treated LPS (p>0.05). 4. The levels of all three cytokines released from PMN stimulated with P.endodontalis LPS were significantly lower than those released from PMN stimulated with E. coli LPS (p<0.05).
