Alendronate is a bisphosphonate that selectively inhibits osteoclast-mediated bone resorption. Dosing convenience is an important element for the enhancement of patient compliance and the effective management of osteoporosis. The purpose of this study was to compare the effectiveness and compliance among alendronate pharmaceutical products (oral once-weekly alendronate 70 mg, daily alendronate 10 mg, and once-weekly alendronate 70 mg with Vitamin $D_3$ 2800 IU) in terms of the change in bone mineral density (BMD), biochemical markers, and compliance estimates. A retrospective chart review was conducted in patients with osteoporosis who received alendronate 70 mg (Group 1), alendronate 10 mg (Group 2), or alendronate 70 mg with Vitamin D3 2800 IU (Group 3) at the endocrinology department of a hospital in Korea from Jan. 1, 1998 to Mar. 31, 2008. The primary endpoints were the increases in spine antero-posterior BMD T-score and femur trochanter BMD T-score, and the compliance of alendronate products. Secondary endpoints included changes in bone turnover-related biochemical markers including bone-specific alkaline phosphatase, urinary N-terminal telopeptides (NTX) and osteocalcin, and in serum vitamin $D_3$ concentration. There was no statistical difference in the BMD increase among the three alendronate products; spine BMD T-score increased by $0.49{\pm}0.52$, $0.39{\pm}0.48$ and $0.50{\pm}0.41$, and femur trochanter BMD T-score by $0.29{\pm}0.42$, $0.21{\pm}0.53$ and $0.24{\pm}0.22$ in Group 1, 2 and 3, respectively. With respect to the increases in femur trochanter BMD T-score and the decreases in NTX and osteocalcin, 70 mg once-weekly group was remarkably superior to 10 mg daily group (p < 0.05) The compliance of 70 mg once-weekly group was significantly higher than that of 10 mg daily treatment group (p < 0.001). In conclusion, all three alendronate treatment groups were equivalent in effectiveness, and the compliance of 70 mg once-weekly group was better than that of 10 mg daily treatment group.

Recently, it was reported that enamel matrix derivative may be beneficial in periodontal regeneration procedures in expectation of promoting new bone and cementum formation. The aim of present study was to evaluate the effect of enamel matrix derivative($Emdogain^?$)and Caso4 sulfate paste in 1-wall intrabony defects in beagle dogs. Surgically created 1-wall intrabony defects were randomly assigned to receive root debridement alone or $Emdogain^{(R)}$ or $Emdogain^{(R)}$ and Caso4. Clinical defect size was 4 X 4mm. The control group was treated with root debridement alone,and Experimental group I was treated with enamel matrix derivative application, and Experimental group II was treated with enamel matrix derivative and Caso4 sulfate paste application,. The healing processes were histologically and histometrically observed after 8 weeks and the results were as follows: 1. The length of junctional epithelium was $0.41{\pm}0.01mm$ in the control group, $0.42{\pm}0.08mm$in the experimental group I and $0.50{\pm}0.13mm$in the experimental group II. 2. The connective tissue adhesion was $0.28{\pm}0.02mm$ in the control group, $0.13{\pm}0.08mm$ in the experimental group I and $0.19{\pm}0.02mm$ in the experimental group II. 3. The new cementum formation was $3.80{\pm}0.06mm$ in the control group, $4.12{\pm}0.43mm$ in the experimental group I and $4.34{\pm}0.71mm$ in the experimental group II. 4. The new bone formation was $1.43{\pm}0.03mm$ in the control group, $1.53{\pm}0.47mm$ in the experimental group I and $2.25{\pm}1.35mm$ in the experimental group II. Although there was limitation to present study, the use of enamel matrix derivative in the treatment of periodontal 1-wall intrabony defect enhanced new cementum and bone formation. Caso4 sulfate paste will be the candidate for carriers to deliver enamel matrix derivative, and so enhance the regenerative potency of enamel matrix derivative.

Objectives : The purpose of this study was to correlation between the index of dental caries in primary teeth and the habits of diet and snack which are expected to influence on the index. The subjects of this study were 165 parents of the children who visited a pediatric dental hospital located in Gyeong-gi do from Jun. 15th to Sep. 26th, 2009, and the self-report questionnaire survey was performed. Methods : A questionnaire used in a previous study was revised and completed for this study and it consisted of 15 items on general characteristic, nine items on dietary habit, and five items on snack intake habit. The collected data was analyzed using SPSS program and findings are as follows Results : 1. The index of dental caries in primary teeth by ages was that children of four years old has 4~5 with 27.5%, children of five years old has 2~3 and 4~5 with 33.3% and children of six years old has 1 and 8~9 with 25.6%, showing a statistically significant(${\chi}^2$=37.72, p<.01). 2. The frequency of brushing teeth was found to have statistically significant negative correlation with the number of primary teeth with dental caries (${\chi}^2$=61.20, p<.001). 3. The frequency of taking snack was found to have statistically significant positive correlation with the number of primary teeth with dental caries (${\chi}^2$=51.42, p<.001). 4. The desirability of dietary habit was found to have statistically significant negative correlation with the number of primary teeth with dental caries (${\chi}^2$=36.51, p<.001). 5. The frequency of taking biscuit was found to have statistically significant positive correlation with the number of primary teeth with dental caries (${\chi}^2$=67.74, p<.001). 6. The frequency of taking bread was found to have statistically significant positive correlation with the number of primary teeth with dental caries (${\chi}^2$=29.63, p<.01). 7. The frequency of taking caramel and candy was found to have statistically significant positive correlation with the number of primary teeth with dental caries (${\chi}^2$=38.85, p<.001). 8. The frequency of taking soft drinks was found to have statistically significant positive correlation with the number of primary teeth with dental caries (${\chi}^2$=52.92, p<.001). 9. The frequency of taking ice-creams was found to have statistically significant positive correlation with the number of primary teeth with dental caries (${\chi}^2$=75.07, p<.001). Conclusions : Those findings show that the children with undesirable dietary habit and higher frequency of taking snack have higher index of dental caries in primary teeth, therefore, it is considered that the regular brushing teeth and establishment of desirable dietary habit are very important for keeping health oral cavity. It is recommended that the continuous concern and repeated learning are needed in house and group of rearing infants so that the children take foods of fruits which have function of self-purification than the food of carbohydrates which has high adhesion and level of sweetness.

The purpose of this study was to examine the effects of sensory integration therapy (SIT) on sensory' motor development and adaptive behavior of cerebral palsy children. The design of this study was quasi experiments with a non-equivalent pre- and post-test control design. Subjects of the study were arbitrarily chosen based on predetermined selection criteria among the cerebral palsy children who were treated as out-patients at two rehabilitation hospitals one in Seoul, and the other in Kyunggi-do. The study was conducted between early April and late July in 2000. Fifteen children were in the experimental group and eleven in the control group. The allocation was done based on ease of experimental treatment. A five-step SIT program was devised from a combination of SIT programs suggested by Ayres(1985) and Finks(1989), and an author-designed SIT program for cerebral palsy children. The experimental group was subjected to 20 to 30 minutes of SIT per session. two sessions a week for ten -week period. The effects of SIT were measured with respect to 9 sub-areas that can be administered to cerebral palsy children out of a total of 17 sub-areas in the Southern California Sensory Integration Test (SCSIT) developed by Ayres (1980). In addition. the scale developed by Russell (1993) for Gross Motor Function Measure (GMFM). and Perception Motor Development Test developed by 中司利一 et al.(1987) were also applied. Adaptive behavior was analyzed using guidelines in two unpublished documents - School-Age Checklist for Occupational Therapy by the Wakefield Occupational Therapy Associates, and the OTA-Watertown Clinical Assessment by the Watertown Occupational Therapy Associates-, and an author-developed Adaptive Behavior Checklist. Collected data were statistically analyzed by SPSS PC for chi square test, Mann-Whitney test, Wilcoxon signed rank test, and paired t-test. The results were as follows: 1. In sensory development, the experimental group exhibited a score increase compared to the control group, but the difference was not statistically significant, Although the experimental group showed improvements in all. 9 sub-areas compared to the control group, only right-left discrimination exhibited statistically significant change. 2. In gross motor development, the experimental group showed improvements in score compared to the control group, but it was not statistically significant. In fine motor development, the experimental group exhibited statistically significant improvements compared to the control group. In sub-area analysis, figure synthesis showed positive change. 3. In adaptive behavior development, post-experimental adaptive behavior scores were higher compared to pre-experimental scores with statistical significance. Furthermore, sub-areas emotional behavior, perception behavior, gross-fine motor function, oral-respiration function, motor behavior, motor planning, and adaptive response exhibited higher scores after SIT. In conclusion SIT was found to be partially effective in sensory and fine motor development, effective in all adaptive behavior areas, and not effective in gross motor development. Thus, this study has shown that SIT is an effective intervention for sensory development, fine motor development, and adaptive behavior for cerebral palsy children. But, for the effectiveness of SIT on gross motor development, further studies employing longer-time experiments are recommended.

치과방사선 검사에 있어 방사선작업종사자의 위치에 따라 방사선 노출 정도를 평가하고자 촬영실과 납유리, 조작대에서 방사선량률을 측정하였다. 사용된 장치로는 Standard(Max-GLS, Shinhung), 파노라마(PCH-2500, Vatech), 세팔로(PCH-2500), Cone beam CT(PHT-30LFO, Vatech)이며, 방사선측정기는 PM1405 장비이다. 촬영조건은 임상에서 사용하는 인자와 동일하게 설정하였다. 그 결과 촬영실 안에서는 Cone beam CT가 98 uSv/h로 가장 높았으며, standard가 0.4 uSv/h로 가장 낮은 수치를 보였다. 또 파노라마가 촬영방식이 다름으로 인하여 세팔로 보다 높게 측정되었다. 납유리 표면과 조작대에서는 구강내와 파노라마, 세팔로는 모두 기록준위 이하로 측정되었지만, Cone beam CT는 누설선량이 있는 것으로 측정되었다. 이에 방사선작업종사는 적절한 방호도구를 하고 촬영시간을 최대한 줄여야 한다. 또, 방사선실의 구조 또한 효율적으로 설계해야 할 것이다. 치과방사선검사는 최근 지속적으로 증가하고 있기 때문에 환자와 방사선작업종사자에 대한 적절한 방호 대책이 필요하다.

Background: Gastric cancer (GC) is one of the most common cancers in China. Adjuvant chemotherapy (AC) is a routine auxiliary treatment for GC recommended by the guidelines issued in 2011 by the Ministry of Health of the People's Republic of China, but the relevant credible consequences in China have been insufficient because of China's late start and ethical concerns. Methods: A series of databases, including Cochrane Library, MEDLINE, EMBASE, the Chinese database of the National Knowledge Infrastructure and the VIP database, were searched by 2 reviewers independently for studies investigating AC for GC through March 2012. The retrieved literature was screened according to the eligibility criteria. Results: A total of 35 randomized control trials (RCTs) were subjected to the final analysis, including 4,043 patients in treatment group and 3,884 in the control group, as well as 4 clinical-control trials (CCTs), which accessed the final analysis with 238 and 252 patients, respectively. AC reduced the risk of death as a protective treatment with statistical significance (HR=0.91, 95%CI: [0.85, 0.97], P=0.002), and it seemed more effective for Asian than non-Asian patients. The effects of AC were not influenced by the starting time (P>0.05). D2 lymphadenectomy-based chemotherapy was effective (HR=0.89, 95%CI: [0.80, 0.99], P=0.04). Oral S-1 40 mg/m2 after D2 lymphadenectomy might be a better choice for Asians with advanced GC and might result in a greater reduction of adverse events than in non-Asian patients. GRADE quality assessment determined that the strength of the evidence from foreign studies from Europe, the United States and Asian countries other than China was high, while it was moderate for Chinese studies. Conclusion: AC was effective or even curative in Chinese patients in general, although it is still necessary to optimize a targeted AC scheme for Chinese patients with GC.

본 연구는 약쑥의 기능성 성분인 jaceosidin이 제1형 당뇨병에서 혈당과 체내 항산화 상태에 미치는 영향를 조사하고자 실시되었다. jaceosidin을 식이에 농도별(0.005%, 0.02%)로 혼합시켜 준비하였으며, 실험 동물은 C57BL/6J 5주령 수컷 마우스를 사용하여 정상군(Normal)과 당뇨군으로 나눈 뒤 당뇨군의 마우스는 5일간 streptozotocin (55 mg/kg bw)을 복강으로 주사하여 당뇨를 유발하였다. 당뇨군은 당뇨대조군(D-Control), jaceosidin 0.005% 섭취군(D-0.005%), jaceosidin 0.02% 섭취군(D-0.02%)으로 나누어 사육하였다. 8주간의 식이 섭취 결과, 당뇨군의 체중이 Normal과 비교하여 유의적으로 감소되었고, 식이효율은 유의적으로 낮아졌으며, jaceosidin의 섭취는 당뇨로 인한 체중 및 식이효율 저하에 영향을 미치지 않는 것으로 나타났다. 제1형 당뇨시 jaceosidin의 섭취가 장기 무게와 간 기능에 영향을 미치지 않는 것으로 나타났으나, 공복 혈당은 D-0.005%가 D-Control과 비교하여 유의하게 감소하는 것으로 나타났으며, 농도의존적은 경향은 보이지 않았다. 당부하검사에서는 당뇨군이 normal에 비해 혈당과 AUC 값이 유의적으로 높게 나타났으나, jaceosidin 섭취에 의한 차이는 없는 것으로 나타났으며, 인슐린 내성검사 결과에서는 D-0.02%가 당뇨 대조군보다 AUC값이 감소하는 경향을 보였다. Jaceosidin의 섭취가 당뇨병로 인한 산화적 스트레스에 미치는 영향을 측정한 결과, jaceosidin의 섭취가 과산화지질 생성에는 영향을 미치지 않는 것으로 나타났으나, 항산화효소인 GSH-px의활성은 D-Control과 비교하여 유의적으로 증가시켰다. 이상의 결과로 미루어 볼 때, jaceosidin은 제1형 당뇨병시 간의 항산화 효소계를 활성화 시킴으로써 공복혈당을 낮추고, 인슐린민감성을 증가시키는 것으로 생각되는 바 당뇨병이나 당뇨로 인한 합병증 예방 및 치료에 활용될 수 있을 것으로 판단된다.

Objectives: The purpose of this study was to observe the reaction kinetics and the degree of polymerization of composite resins when cured by different light sources and to evaluate the effectiveness of the blue Light Emitting Diode Light Curing Units (LED LCUs) compared with conventional halogen LCUs. Materials and Methods: First, thermal analysis was performed by a differential scanning calorimeter (DSC). The LED LCU (Elipar Freelight, $320{\;}mW/\textrm{cm}^2$) and the conventional halogen LCU (XL3000, $400{\;}mV/\textrm{cm}^2$) were used in this study for curing three composite resins (SureFil, Z-250 and AEliteFLO). Second. the degree of conversion was obtained in the composite resins cured according to the above curing mode with a FTIR. Third, the measurements of depth of cure were carried out in accordance with ISO 4049 standards. Statistical analysis was performed by two-way ANOVA test at 95% levels of confidence and Duncan's procedure for multiple comparisons. Results: The heat of cure was not statistically different among the LCUs (p > 0.05). The composites cured by the LED (Exp) LCUs were statistically more slowly polymerized than by the halogen LCU and the LED (Std) LCU (p < 0.05). The composite resin groups cured by the LED (Exp) LCUs had significantly greater degree of conversion value than by the halogen LCU and the LED (Std) LCU (p =0.0002). The composite resin groups cured by the LED (Std) LCUs showed significantly greater depth of cure value than by the halogen LCU and the LED (Exp) LCU (p < 0.05).

This study compared the short-term(4 months) clinical results of regenerative therapy with bioabsorbable membranes($BioMesh^{(R)}$) and bone allograft for the treatment of periodontal(intrabony and furcation) defects in smokers and nonsmokers.(16 smokers) 32 subjects with 92 defects participated in the study(46 in smokers and 46 in non-smokers). This study also evaluated a bioresorbable barrier with and without decalcified freeze-dried bone allograft(DFDBA). The 92 periodontal defects were randomly treated with either the resorbable barrier alone or resorbable barrier in combination with DFDBA following thorough defect debridement and root preparation with tetracycline. Each patient received both types of treatment modalities. Clinical examinations(probing depth, gingival recession, clinical attachment level, plaque index and gingival index) were carried out immediately before and 4 months after surgery. Significant(p<0.001) gains in mean attachment level were observed for both smokers(2.93mm) and non-smokers(3.30mm) but there were not significant difference between two groups. Similarly, significant reductions in mean probing depthshowed for smokers(4.52mm) and non-smokers(4.26mm). However, when comparing gingival recession, smokers were found to exhibit significantly poorer treatment results(1.59mm vs 0.96mm, p<0.05). Using the split-mouth-design, no statistically significant difference between the two modalities could be detected with regard to pocket depth reduction, gingival recession, or attachment gain. These results illustrate that the attachment gain is better in the non-smoker and the best in the non-smoker with the combination therapy of resorbable barrier and DFDBA than with resorbable barrier alone but smoking had no significant effect on clinical treatment outcome, even though smokers show more significant gingival recession. In addition, both treatments, either resorbable barrier plus DFDBA or resorbable barrier alone, promoted significant resolution of periodontal defects but the addition of DFDBA with a bioabsorbable membrane appears to add no extra benefit to the only membrane treatment.
