Dental resin composites were introduced commercially in the mid-1960s for the restoration of anterior teeth. Since their advent, resin composites have undergone significant development, which continues to improve the longevity and application of resin composite restorations. Despite the development of new dentin-bonding agents, no system is currently available that completely withstands the formation of contraction gaps at the cementum/dentin-restoration junction, due to the unavoidable polymerization shrinkage of the resin composite during setting, therefore, a major aim of this study was to minimize or control the polymerization shrinkage of composites allowing flow of resin during setting reaction. A thermal dilatometer (DIL 402C, TASC 414/3A Controller, Netzche, Germany) was used to measure and compare conventional continuous cure and pulse cure polymerization shrinkage of seven light curing dental composites and three compomers. For conventional cure, restorative material were polymerized for 2 minutes using VIP (Bisco, U.S.A.) with 400 ㎽/㎠ intensity. After then, further polymerization was allowed for next 12 minutes that total 14 minutes of shrinkage was measured. For pulse cure, material was pre-polymerized irradiating light for 5 seconds with 200 ㎽/㎠ and post-ploymerized 3 minutes later with 400 ㎽/㎠ for 2 minutes. 9 minutes were allowed for further polymerization that total 14 minutes of shrinkage was measured. Polymerization shrinkage ranged from 3.758 ㎛/㎜ (SYC) to 6.897 ㎛/㎜ (P60) for conventional cure and 4.026 ㎛/㎜ (FLT) to 6.996 ㎛/㎜ (SRF) for pulse cure. The highest difference between the two methods was found at EAN (2.713 ㎛/㎜), followed by F20 and CRA which showed significant differences of 2.133, 1.274 ㎛/㎜ respectively (p<0.05). The least difference was found at SYC (0.489 ㎛/㎜). Universal resin composite group showed the highest polymerization shrinkage (6.514±0873 ㎛/㎜), and flowable composite showed the least shrinkage (4.139 ㎛/㎜). Packable composite showed 5.090±1.906 ㎛/㎜, and compomers showed 6.129±2.652 ㎛/㎜.

Peripheral nerve injuries are a commonly encountered clinical problem and often result in severe functional deficits. To understand the effects of various therapeutic measures on functional recovery after peripheral nerve injury, we made a crush injury to the sciatic nerve of 114 Sprague-Dawley rats, and one of the three therapeutic measures; exercise, electrical stimulation, and laser irradiation, was applied. And then, we analysed the sciatic nerve functional index (SFI) once a week following the injury. It was shown that sciatic nerve crush injury developed characteristic gait changes dropping the sciatic function index (SFI) value, and then this value was slowly recovered. Two to three weeks following the injury was the most important periods for the functional recovery regardless of the therapeutic measures applied. At the stages of recovery, laser irradiation has better effects than electrical stimulation, and exercise training. These results suggested that application of various therapeutic measures after nerve injury is effective in the functional recovery, and the appropriate selection of therapeutic measure according to the clinical stages may be important for the optimal functional recovery.

Acupuncture, an over 2500 years old therapeutic method stemming from traditional oriental medicine, is nowadays wide open to modern medical science. With the widespread usage of acupuncture, the number of article about biomechanical or therapeutic effects of acupuncture from animal experiments and clinical trials is largely reported. In a previous study, we have reported that Joksamlee(ST36) acupuncture increases serum protein and glucose but decrease serum lipid and cholesterol. For further study, we was examined effects of Shenshu(B23) and Samumgyo(SP6) acupuncture stimulation on differential blood components in growing and adult male rate. 24 male Sprague-Dawley rats were randomly assigned into three groups; A1 (B23 and SP6 acupuncture in adult rats) group, A2 (B23 acupuncture in growing rats) group, and control group. The results obtained were as follows; 1. Body weight was significantly decreased in A1 and A2 groups. 2. Serum TP level was not changed, but albumin level was significantly increased in A2 group. 3. Serum glucose level was significantly increased in A1 group. 4. Serum TG level was significantly decreased in A2 group: PL level was significantly decreased in both A1 and A2 groups; FFA level was not changed. 5. Serum T.CHO, HDL-C and LDL-C levels were not changed in both A1 and A2. 6. Serum amylase activity was significantly increased in A1 group.

광원의 종류에 따른 콤포짓트레진의 중합도

윤태호,이용근,임범순,김철위 대한치과기재학회 2001 대한치과재료학회지 Vol.28 No.1

콤포짓트레진의 중합도와 속도는 광원의 종류와 광조사 시간에 따라 영향을 받는다. 현재 할로겐 램프를 중합에 많이 사용하고 있으나 전구의 수명이 짧고, 시간경과에 따라 광선의 출력이 감소하므로 중합도는 낮아져 물성이 감소하고 수복물이 실패할 가능성도 높다. 이를 개선하기 위하여 콤포짓트레진 중합에 사용할 수 있는 LED (blue light emitting diode) 와 플라즈마 아크 기술이 소개되었다. 이 실험에서는 3 종의 광원(할로겐 램프, LED 및 플라즈마 아크) 에서 광조사시간을 달리하여 광에너지의 총량을 변화하는 조건으로 점주도가 서로 다른 3 종의 콤포짓트레진에서 깊이에 따른 중합도를 측정하여 각 광원의 효율성을 상호 비교하였다. 할로겐 램프, LED 및 플라즈마 아크 조사기로 광에너지 총량이 각각 8J/㎤와 16J/㎤ 이 되도록 중합하고 표면에서 1, 2, 3 및 4mm 위치에서 100㎛ 의 두께로 절단하였다. 시편 두께가 50~70㎛ 가 되도록 연마하고 FT-IR 로 표준기선법에 따라 중합직후의 중합도를 측정하였다. 중합방법 및 광조사 부위에서 깊이에 따른 평균 중합도를 계산하여 3 원 분산분석 및 Scheffe 의 방법에 따라 유의수준 0.05 에서 검정하였다. 이 실험에서 다음과 같은 결과를 얻었다. 재료, 깊이 및 광조사 시간 모두 전환율에 유의한 영향을 주었다(p〈0.01). 3 종 광원의 표층에서 1mm 깊이에서의 중합도는 저점도(RVN) 〉중점도(Z25) 〉응축형 콤포짓트레진(SRF) 순이었다(p〈0.05). 3종 광원의 중합도는 유의한 차이를 볼 수 없었다(p〉0.05). 3종의 조사광원 모두에서 광에너지 총량을 2배로 증가한 경우, 중합도는 2mm 깊이까지는 유의한 차이가 없었으나(p〉0.05), 3mm 부터는 광에너지 총량 증가에 따라 유의하게 증가하였다(p〈0.05).

연구목적 : 잠재성 간성혼수 환자들의 신경인지기능 장애 정도와 기저 핵이나 두정엽 백질부에서의 자기공명분광 (proton MRS)으로 측정한 양성자 함유 화합물의 변화와의 상관관계를 조사하고자 하였다. 방법: 한국판 웩슬러 지능 검사(KWIS) 중 토막짜기나 기호 바꾸기, 그리고 번호잇기 검사를 적용하여 잠재성 간성혼수로 정의된 18명의 간경변 환자를 대상군으로 하고 20명의 정상인을 대조군으로 하였다. 복합주의력과 시각 정보 분석능력 측정을 위해 Vienna 전산화 신경인지기능 검사 중, Cognitrone 검사. 미세 협응 운동능력을 위해 Grooved pegboard 검사를 적용하였단 1.5 Tesla 임상용 자기공명 촬영기를 이용해 자기공련명 분광을 얻었으며 두정엽 백질부와 기저핵의 각각 2×2×2cm3 vocel에서의 myoinositol(ml), N-acetyl-L-aspartate(NAA). creative(Cr), choline(Cho) 등의 농도를 측정하고 Cr 농도에 대한 상대적 농도비율을 구하여 분석하였다. 결과: 1) 잠재성 간성혼수 환자들의 기저핵과 두정엽 백질부에서 Cho/cr 및 ml/Cr 비가 감소하였다. 2) 미세 협응 운동능력을 반영하는 Grooved pegboard 검사의 수행능력이 기저핵의 ml 및 두정엽 백질부의 Cho농도와 유의미한 역상관관계를 보였다(r= -0.59. p<.05). 3) Cognitrone 검사 중 정반응하는데 걸리는 평균시간은 두정엽 백질부의 NAA와 역 상관관계를 보였다(r= -0.55, p<.05) . 결론 : 잠재성 간성혼수 환자들의 특정 신경인지기능의 장애는 양성자 자기공명분광법으로 측정한 기저핵 및 두정엽 백질부의 신경화학적 변화와 상관관계를 보인다. 하지만 이러한 신경화학적 변화가 잠재성 간성 혼수의 근본적 병리 생리인지 2차적 변화인지를 규명하기 위해서는 질병의 경과에 따른 신경인지기능 및 양성자 자기공명분광 소견의 추적연구가 필요하며 비슷한 인지기능의 장애를 보이는 다른 신경퇴행성 질환과의 비교 연구가 필요하다. 0bjectives To investigate the relationship of neurochemical changes of brain in SCHE patients and the level of cognitive function, the authors measured hydrogen containing neurochemicals in two brain regions using 1H MRS, and compared those changes with the level of cognitive performances such as attention, visual analysis, or fine motor function. Methods ; A total of patients with liver cirrohosis were defined as SCHE, for they performed poorly(out of 1 SD of normative data) in more than one neuropsychological tests conventionally used(digit symbol and block design tests in KWIS, trail making test A and B). They were further evaluated in attentional ability and efficacy of visual analysis using Cognitrone subtest in Vienna Neurocognitive Test battery. Fine motor coordination were also measured by Grooved Pegboard test. Patients and 20 nodal controls underwent proton MRS study. Proton containg neurochemirals , such as myoinositol(mI) , N-acetrl-L-aspartate(NAA) , creating (Cr) , choline(Cho) were measured from 2*2*2cm3 voxel of basal ganglia and parietal white matter using 1.5 tesla dinical MRI/MRS system. The ratios of above metabolites to Cr were analyzed. Results : 1) Patients with SCHE showed reductions in Cho/Cr and ml/Cr in both basal ganglia and parietal white matter compared to normal subjects. 2) Performance of Grooved Pegboard test were negatively correlated with ml level of basal gang1ia and with Cho level of parietal white matter(r= -0.59, p<.05). 3) Mean time of correct responses in Cognitrone test skewed negative correlation with NAA level of parietal white matter(r= -0.55, p<.05). Conclusion : Certain neurocognitive disturbances in SCHE patients seemed to be related with neurochemical changes in basal ganglia or parietal white matter. To further elucidate the relationship of focal biochemical changes and neurocognitive deficits in SCHE patients, however, fo11ow-up study according to the illness stage must be performed. Studies on other disorders showing similar cognitive deficit patterns would be helpful.
