Objectives : This study aimed to examine the effect of biofeedback treatment on the clinical symptoms and stress responses in chronic headache patients. Methods : We recruited 18 chronic headache patients who were treated with 8 sessions of biofeedback treatment and 18 age and sex-matched control headache patients. All subjects consisted of patients with chronic tension headache and migraine hea-dache. Stress responses were measured using Symptoms of stress (SOS) inventory and all subjects performed Beck depression inventory (BDI), Spielberger state anxiety inventory (STAIS), and visual analogue scale (VAS). Biofeedback physiological vaiiables including frontal and forearm EMG, electrodermal response (EDR) and skin temperature at pre-and post-treatment were also measured in all subjects. Results : Compared with control patients, patients on biofeedback treatment showed significant reduction in scores of STAIS(t=3.705,P<.001),andVAS (t=3.392, p=.001) as well as SOS subscales ; peripheral manifestations (t= 1.788, P=.042), habitual pattems (t=2.008, P=.027), depression (t=2.081, P=.023), anxiety (t= 1.990, P=.028), and total score (t=2.045, p=.025). There was a significant increase of skin temperature (t= -1.835, P=.038) only in the biofeedback treatment group. Conclusion : These results suggest that biofeedback treatment may be effective in relieving chronic headache by reducing psychological and physiological stress responses.

장범철,김기홍 용인대학교 대학원 2010 특수체육연구 Vol.7 No.-

본 연구는 운동선수, 일반인, 지적장애인을 대상으로 키네시오 테이핑 처치가 유연성과 최대근력에 변화에 미치는 영향을 알아보는데 목적이 있다. 실험에 참가한 대상자들은 키네시오 테이핑 전 유연성(좌전굴, 체후굴)과 최대근력(상완이두근, 대퇴사두근)을 측정하였으며 키네시오 테이핑 처치 후 유연성과 최대근력을 측정하였다. 결과에 따른 자료처리는 세 집단의 차이를 알아보기 위해 각 변인에 대하여 평균 및 표준편차를 산출하기위해 기술통계분석(Descriptive Statistics Analysis)을 실시하였다. 평균과 표준편차를 산출한 후 유연성 변인(가설1)과 최대근력 변인(가설2)의 사전·사후 변화 분석을 공변량 분석(ANCOVA)으로 실시하였다. 통계적 유의수준은 P<.05 수준으로 하였다. 이러한 방법으로 연구한 결론은 다음과 같다. 첫째, 키네시오 테이핑 전·후 유연성(좌전굴, 체후굴)의 변화에서 유연성이 증가하였으나 통계적으로 유의한 차이는 없었다. 둘째, 키네시오 테이핑 전·후에 최대근력의 변화(상완이두근, 대퇴사두근의 flexion, extension)에서 상완이두근의 extension에서 통계적 유의한 차이를 보였으며 통계적으로 유의한 차이를 보이지 않는 집단에서도 테이핑 처치 전보다 후에 최대근력이 증가하였다. 요약하면 키네시오 테이핑 처치 전·후에 유연성과 최대근력이 증가하였으며 이는 집단에 상관없이 테이핑 처치 후에 유연성과 최대근력이 향상되어 효과가 있었다. 본 연구에서 밝혀진 결과를 종합하면 지적장애가 있는 사람들을 대상으로 더욱 다양한 방법으로 테이핑 효과를 연구하여 테이핑 처치 전과 후의 유연성과 최대근력이 증가하는 효과뿐만 아니라 심리적인 요인을 분석하는 연구가 이루어 져야 할 것이며 키네시오 테이핑의 효과를 스포츠 현장의 다양한 기록경기에서 분석하는 연구가 이루어져야 할 것이다. This study was to investigate the effects of kinesiotaping methods on the flexibility and maximum muscle strength in targeting of the athletes, general people, and people with intellectual disability. The body flexibility was measured by bending upper body front at sitting position and bending behind in standing position and the maximum muscle strength of upper arm bicep and quadriceps femoris muscle was measured within pre and post kinesiotaping period. The descriptive statistical analysis to calculate mean and standard deviation on each variance were used for data analysis within three groups of sample subjects. After getting mean and SD, the variance of flexibility as the first hypothesis and the variance of muscle strength as the second hypothesis were statistically analyzed by ANCOVA between pre and post test results in the significance level of .05. The results of this study were as follows:First, there were no significant differences between pre and post kinesiotaping treatment in the body flexibility of bending upper body front and back, however, the improvement was shown in the body flexibility. Second, there were significant differences between pre and post kinesiotaping treatment in maximum muscle strengths of bicept flexion and quadriceps femoris flexion and extension both. Even though no significant differences was shown in the test results, the positive improvement of body flexibility and muscle strength were indicated. In conclusion, the positive enhancement in body flexibility and maximum muscle strengths were shown in all subject groups before and after kinesiotaping treatment. Therefore, the taping methods specially kinesiotaping treatment could be assistive for the people with intellectual disability in their enhancement of body flexibility and muscle power to be effective for their own physical activities or performances. Further, the other research such as psychological approach could be examined using this kinesiotaping on the people with intellectual disability.

Lidocaine에 의한 경련이 뇌조직에서 c-fos 발현에 미치는 영향

조성범,채한정,강장숙,김형룡 원광대학교 생체재료·매식연구소 1998 원광생체재료·매식 Vol.7 No.1

Recently, a variety of stimuli including convulsion, ischemia and noxious stimuli have been shown to induce the expression of c-fos mRNA in central nervous system (CNS). In this study, c-fos expression in both mRNA and protein (Fos) levels is examined up to 72 hr in brain regions, including hippocampus, piriform cortex, neostriatum, amygdala, dentate gyrus, cerebral cortex, and thalamus during lidocaine-inducced convulsion. Intraperitoneal administration of lidocaine (120 mg/kg) induces generalized convulsion of rats within 10 min and subsequent increase of c-fos expression in both mRNA and Fos protein levels in dentate gyrus, piriform cortex, amygdala, neostriatum, cerebral cortex, hippocampus, and thalamus. A prominent induction of c-fos mRNA and Fos protein in dentate gyrus suggests that dentate gyrus plays an important role in the process of lidocaine-induced convulsion. These results suggest that c-fos may participate in plastic changes of central nervous system associated with stimuli such as seizure activity.

All-in-one 접착제에서 초음파진동이 법랑질과 상아질의 결합강도와 레진침투에 미치는 영향

이범의,장기택,이상훈,김종철,한세현 大韓小兒齒科學會 2004 大韓小兒齒科學會誌 Vol.31 No.1

초기의 접착 시스템은 여러 단계의 술식을 필요로 하였으며 술자의 기술과 재료의 성질에 크게 좌우되었으나 최근 산부식, priming, adhesive를 한번에 적용할 수 있는 a11-in-one adhesive system이 등장하였다. 치과에서의 vibration의 이용은 치석의 제거 및 접착제의 점도를 낮추는데 이용되어왔으며 vibration은 접착제의 흐름성을 향상시켜 film thickness를 낮추어 수복물 주위의 미세누출을 줄이는데 도움을 준다. 이에 저자들은 all-in-one adhesive system에서 vibration이 법랑질과 상아질의 접착강도와 레진침투에 미치는 효과를 알아보고자 하였다. 법랑질 시편은 발거 후 실온에서 0.1% thymol 용액에서 보관된 30개의 건전한 사람의 대구치를 무작위로 10개씩 세군으로 나누고 근원심 방향으로 두 부분으로 분리하여 각각은 같은 접착제를 사용하고 초음파진동여부를 다르게 하였고, 아크릴 레진을 이용하여 직경 1-inch의 PVC관에 매몰한 후 협설면이 아크릴봉과 동일한 높이가 되도록 220-, 600-grit 연마지로 순차적으로 연마하였고 군당 10개씩 여섯 군으로 분류하였다. 1군과 2군은 Prompt L-Pop(3M-ESPE, Seefeld, Germany), 3군과 4군은 One-Up Bond F(Tokuyama Corp., Tokyo, Japan). 5군과 6군은 AQ bond(Sun Medical Co., Kyoto, Japan)를 제조사의 지시에 따라 도포하였다. 2군, 4군, 6군은 초음파 치석제거기를 이용하여 치면에 대고 15초간 진동을 가한 후 광중합하였다. 상아질 시편은 치관부 법랑질을 제거한 후 상아질면을 아크릴 봉과 동일한 높이가 되도록 하고 법랑질 시편과 동일하게 처리하였다. 이후 직경 2mm, 높이 3mm의 Teflon mold(Ultradent, U.S.A.)를 이용하여 복합레진을 충전한 후 40초씩 두 번에 나누어 광중합한 후 24시간동안 실온에서 증류수에 보관하였다. 열순환 시행한 후, 만능측정 기(Instron4465)로 전단결합강도를 측정하였으며 Resin tag의 양상을 비교하기 위해 각 군의 시편의 치질을 완전히 용해 시킨 후 표면을 주사전자현미경사진으로 관찰하여 다음과 같은 결과를 얻었다. 1. 법랑질에서 초음파 진동을 가한 군(2,4,6군)은 가하지 않은 군(1,3,5군)에 비해 평균 전단결합강도가 높게 나타났다. 그 차이는 AQ bond 군을 제외하고 통계적으로 유의하였다(p<0.05). 2. 상아질에서 초음파 진동을 가한 군(2,4,6군)은 가하지 않은 군(1,3,5군)에 비해 평균 전단결합강도가 높게 나타났다. 그러나 그 차이는 One-Up Bond F군을 제외하고는 통계적으로 유의한 차이가 없었다. 3. 전자 현미경 관찰에서 초음파 진동을 가한 군에서 더 많은 법랑질의 소실과 상아질에서 resin tag의 길이가 길었고 lateral branch의 수도 많이 관찰되었다. The objective of this study was to apply the vibration technique to reduce the viscosity of bonding adhesives and thereby compare the bond strength and resin penetration in enamel and dentin achieved with those gained using the conventional technique and vibration technique. For enamel specimens, thirty teeth were sectioned mesio-distally. Sectioned two parts were assigned to same adhesive system but different treatment(vibration vs non-vibration) Each specimen was embedded in 1-inch inner diameter PVC pipe with a acrylic resin. The buccal and lingual surfaces were placed so that the tooth and the embedding medium were at the same level. The samples were subsequently polished silicon carbide abrasive papers. Each adhesive system was applied according to its manufacture's instruction. Vibration groups were additionally nitrated for 15 seconds before curing. For dentin specimen, except removing the coronal part and placing occlusal surface at the mold level, the remaining procedures were same as enamel specimen. Resin composite(Z250 3M. U.S.A.) was condensed on to the prepared surface in two increments using a mold kit(Ultradent Inc., U.S.A.) Each increments was light cured for 40 seconds. After 24 hours in tap water at room temperature, the specimens were thermocycled for 1000cycles.. Shear bond strengths were measured with a universal testing machine(Instron 4465, England). To investigate infiltration patterns of adhesive materials, the surface of specimens was examined with scanning electron microscope. The results were as follows : 1. In enamel, the mean values of shear bond strengths in vibration groups(group 2,4,6) were greater than those of non-vibration group(group 1,3,5). The differences were statistically significant except AQ bond group. 2. In dentin, the mean values of shear bond strengths in vibration groups(group 2 4, 6) were greater than those of non-vibration groups(group 1,3,5). But the differences were not statistically significant except One-up Bond F group. 3. The vibration group showed more mineral loss in enamel and longer resin tag and greater number of lateral branches in dentin under SEM examination.

정중과잉치로 인해 회전된 상악 중절치의 치험례

이범의,김영재,김정욱,장기택,이상훈,김종철,한세현 大韓小兒齒科學會 2004 大韓小兒齒科學會誌 Vol.31 No.4

정중과잉치의 원인은 잘 알려지지는 않았지만 dental lamina의 hyperactivity에 의해 발생한다는 가설이 가장 많이 받아들여지고 있다. 이러한 정중과잉치의 병발증으로는 주변 영구절치의 맹출 장애, 만곡 치근, 치근흡수, primordial 혹은 follicular cyst의 형성, 회전, 이환된 부위의 총생 및 비정상적인 정중이개를 일으킬 수 있다. 이러한 이유로 영구전치의 회전이 야기되면 보통 공간의 부족은 적거나 없으며 재발이 흔하므로 과개선이 요구된다. 재발의 방지를 위해서는 조기치료, 과개선, 긴 보정기간, 적절한 접촉면의 형성, 짝힘의 사용, 그리고 수술적인 방법 등이 제안되어왔다. 이에 저자는 정중과잉치로 인하여 심하게 회전된 상악중절치를 주소로 내원한 환아에서 교정적, 외과적 술식을 이용하여 양호한 결과를 얻은 두 증례를 보고하는 바이다. The etiology of mesiodens is unknown but the most widely accepted theory is the hyperactivity of the dental lamina. Complications of mesiodens are delayed or prevented eruption of maxillary central incisors, displacement or rotation of permanent teeth, crowding of affected region, abnormal diastema or permanent space closure, dilaceration or abnormal root development of permanent teeth, primordial or follicular cyst formation, root resorption of adjacent teeth, eruption into nasal cavity. If mesiodens rotate the maxillary central incisors, space deficiency is not common and relapse is very common. So overcorrection is needed. To prevert the rotational relapse, early treatment, overcorrection, long retention period, properly formed proximal surface, use of coupled force, and surgical techniques have been suggested. The authors present two cases, whose chief complain were severely rotated maxillary incisors by mesiodens, treated by orthodontic and surgical technique and showed good results.

EDTA의 적용 온도와 시간에 따른 도말층의 제거양상

신장식,조용범 大韓齒科保存學會 2002 Restorative Dentistry & Endodontics Vol.27 No.5

The purpose of this study was to evaluate the effect of EDTA irrigant according to application time and temperature. 31 human mature extracted teeth with a single canal were sectioned with microtome in 3mm thickness and gained 62 samples of root canals. They were distributed randomly into 6 groups of 10 specimens each and control group of 2 specimens. Each specimens was prepared with GT rotary file (Dentsply, Mallefer Co., Swiss) and irrigated with 3 ml sodium hypochlorite every minute. Then smear layer was removed with EDTA solution (PULPDENT®, PULPDENT Co., USA.) except two control specimens. Specimens of each group were irrigated with 17% EDTA. The time and temperature of application were as follows: <본문참조> All specimens were split longitudinally and prepared for examination by scanning electron microscopy. A set of reference micrographs was used to award a debris score as follows: 0 = no smear layer, all tubules clean and open; 1 = no superficial smear layer, tubule openings visible, but some contain debris plug or soft tissue remnants; 2 = moderate smear layer, some tubules open and others closed; 3 = heavy smear layer, most/all tubule openings obscured. Results were evaluated with Kruskal-Wallis test to determine whether there was statistically significant difference among six groups. Pairs of groups were analyzed using the Student-Newman-Keuls Method and Mann-Whitney test.. The results were as follows: 1. Control specimens showed heavy smear layer at the canal walls. 2. Among the groups applied with EDTA for 2 minutes, group 1 showed the heaviest smear layer, and there was statistically significant difference between group 1 and the other groups(p<0.05). 3. Among the groups applied with EDTA for 5 minutes, group 4 and group 6 showed smear layer, but there was no significant difference between them. 4. Among the groups applied with EDTA for the same temperature, group 1 showed heavier smear layer than group 4, and there was statistically significant difference(p<0.05). 5. Among the groups applied with EDTA for the same temperature, group 2 showed heavier smear layer than group 5 and group 3 showed heavier smear layer than group 6. But there was no statistically significant difference among them. From the results above, it could be concluded, EDTA solution is effective in removing of smear layer when it is applied for 5 minutes. If EDTA is applied for 2 minutes, it should be applied above room temperature.
