In general social opinions of developed cultural state, tattoos induced psychological and social problems. Since Hellenic times, the removal of unwanted tattoos has been a challenge: for example, salabrasion, dermabrasion, LASER surgery, skin graft and cryosugery, etc. But the availability of manay methods for the removal of tattoos appears to indicate that there is no one absolute method. So we studied macroscopical color changes and microscopical histological changes in tattooed rabbits and rats, and overtattooed rabbits and rats. The results were as following: 1. Inflammatory reactions was nearly almost disapperared within 3 weeks. 2. The major fade―out of tattooed color was occurred from post―tattooing 5 days to 3 weeks. 3. Dye particle was located mainly in upper & mid dermis and it was not relafted with tattooing depth. 4. Masking effect of black colored tattoos was definitely improved in the overtattooing group. But complete masking was impossible.

본 연구의 목적은 복합레진을 이용한 비우식성 치경부 5급 병소 수복에 있어서, 3가지 다른 접착제를, 유지구를 부여한 치아와 부여하지 않은 치아에 적용하였을 때의 임상적인 효능의 차이를 비교하기 위함이다. 총 150개의 치아를 각각 25개씩 6개의 군으로 나누었다. A군 Scotchbond Multi-Purpose (SBMP, 3M ESPE, St, Paul, MN, USA, 4세대 접착제)를 사용하고 유지구를 부여하지 않음. B군: SBMP를 사용하고 유지구를 부여. C군: BC Plus (Vericom Co., Anyang, Gyeonggido, Korea, 5세대 접착제)를 사용하고 유지구를 부여하지 않음. D군: BC Plus를 사용하고 유지구를 부여. E군: Adper Prompt (3M ESPE, Seefeld, Germany, 6세대 접착제)를 사용하고 유지구를 부여하지 않음. F군: Adper Prompt를 사용하고 유지구를 부여. 모든 치아는 복합레진인 Denfil(Vericom Co., Anyang. Gyonggido. Korea)을 이용하여 충전하였다. 수복 직후와, 수복 6개월 후에 modified USPHS (United States Public Health Service) criteria에 따라 수복물을 임상적으로 평가하였다. 추가적으로 임상사진을 촬영하였으며, 에폭시 레진을 이용하여 복제한 후 주사전자현미경을 이용하여 이를 관찰하였다. 6개월 후 관찰 결과. alpha rating의 수가 각 실험군마다 동일하지는 않았지만, 통계적으로는 3가지의 접착제간에 유의할만한 차이는 없었고, 기계적인 유지구를 부여한 군과 부여하지 않은 군 간에도 유의할만한 차이는 없었다 (p > 0.05). 그러나 6개월의 관찰 기간은 일반적으로 기대되는 레진의 수명보다 짧기 때문에, 각 실험군 간의 차이를 알아보기 위해서는 추후 더 오랜 기간의 관찰이 요구된다. The purpose of this study is to evaluate prospectively the effect of different bonding systems and retention grooves on the clinical performance of resin restorations in non-carious cervical lesions (NCCLs). Thirty nine healthy adults who had at least 2 NCCLs in their promolar areas were included in this study. One hundred and fifty teeth were equally assigned to six groups; (A) Scotchbond Multi-Purpose (SBMP, 3M ESPE, St, Paul, MN, USA, 4th generation bonding system) without retention grooves; (B) SBMP with retention grooves: (C) BC Plus (Vericom Co., Anyang, Gyeonggido, Korea, 5th generation bonding system) without retention grooves; (D) BC Plus with retention grooves; (E) Adper Prompt (3M ESPE, Seefeld, Germany, 6th generation bonding system) without retention grooves: (F) Adper Prompt with retention grooves. All cavities were filled with a hybrid composite resin, Denfil (Vericom Co., Anyang, Gyeonggido, korea) by one operator. Restorations were evaluated at baseline and at 6-month recall, according to the modified USPHS (United states Public Health Service) criteria, Additionally, clinical photographs were taken and epoxy resin replicas were made for SEM evaluation. At 6-month recall, there were some differences in the number of alpha ratings among the experimental groups. But, despite the differences in the number of alpah ratings, there was no significant difference among the 3 adhesive systems (p > 0.05). There was also no significant difference between the groups with or without mechanical retention (p > 0.05). Follow-ups for longer periods than 6 months are needed to verify the clinical performance of different bonding systems and retention grooves. 〔J Kor Acad Cons Dent 31(4):300-311, 2006〕

Objective To elucidate the effect of task-specific lower extremity training (TSLET) on cognitive and gait function in stroke patients. Methods Thirty-eight patients were assigned to either the TSLET group or the control group. The individuals of TSLET group went through a TSLET plus conventional physical therapy. The control group received two sessions of conventional physical therapy. The primary outcome involved the assessment with visual and auditory digit span test. The secondary outcome was evaluated by the Korean version of Mini-Mental State Examination (K-MMSE) and Global Deterioration Scale (GDS) for cognitive function, Berg Balance Scale (BBS), Time Up and Go Test (TUG), 10 meters Walking Test (10mWT), 6 minutes Walking Test (6MWT), and Korean version of Modified Barthel Index (K-MBI) for gait, balance, and functional ability. Results After intervention (3 weeks) and 2 weeks of follow-up, the TSLET group showed statistically significant improvement in the visual digit span test backwards compared with the control group. In secondary outcome, a significant improvement was observed in GDS, BBS, TUG, and 10mWT in the TSLET group. There was no significant difference between the two groups concerning visual digit span test forward, auditory forward and backward digit span tests, K-MMSE, 6MWT, and K-MBI. Conclusion TSLET could be a useful alternative strategy for improving cognitive and gait function in stroke patients.

Objective:This study examines the risk factors of the falls of the dementic elderlies in the nursing home. Especially we investigated how the psychotropics affect them in the aspect of the falling tendency. Methods:We investigated the falls of the 262 patients living in the Seoul JungGae Nursing Home for six month since March 1 1999. Among these we recruited 182 patients whom the exclusion criteria was applied to, and then we measured the relative risks of risk factors known from the previous studies. Results:The incidence rate of falls is 40.1/100person year. The relative risk of gender, age, disease of central nervous system, chronic illness, cognitive function, antipsychotics, antidepressants and anxiolytics had no significance (p>0.05). BADL, mobility, mood stabilizers were related with the falls significantly, and the relative risks were 0.904 (95%CI 0.840-0.973), 1.744 (95%CI 1.064-2.858), 4.683 (95%CI 1.412-15.532) relatively. Conclusions:The average rate of falling was 40.1/100person year showing less frequent accidents than that of other foreign studies, which was assumed the large number the care-givers and sitting life style on the floor helped preventing the elderlis' falling. Although The gender, age, disease of central nervous system, chronic illness, cognitive function, antipsychotics, antidepressants and anxiolytics did not influence the rate of the falling tendendy of the elderlies, the mobility and impaired activity of daily living increased the rate of their falling. The elderlies taking psychotropics more fell than others not taking pills. The imbalance between the mobile potency and imposed real activity causes the falls. When the psychotropics affect negatively on the mobility, it increases the falling rate of the elderlies. On the other hands, when these affect positively, these prevent elderlies falling.

Objective: To investigate the effects of long-acting injectable 3-monthly paliperidone palmitate on the clinical and social functioning of patients with schizophrenia. Methods: This study enrolled patients with schizophrenia receiving long-acting injectable 1-monthly paliperidone palmitate for at least 4 months and who subsequently received 3-monthly paliperidone palmitate. Accordingly, 418 patients were followed up for 24 weeks. Their clinical symptoms and social functioning were measured using the Clinical Global Impression-Severity of Illness and Personal and Social Performance scales. Results: The Personal and Social Performance total score was significantly higher after 3-monthly paliperidone palmitate treatment than at baseline (baseline vs. week 24: 54.3 ± 18.0 vs. 61.0 ± 14.5 [mean ± standard deviation]; p < 0.001; Wilcoxon signed-rank test); the proportion of patients in the mildly ill group (scores 71−100) also increased significantly (baseline vs. week 24: 16.5% vs. 20.6%; p < 0.001; McNemar-Bowker test). The mean Clinical Global Impression-Severity of Illness score decreased significantly (baseline vs. week 24: 3.7 ± 1.0 vs. 3.4 ± 0.9; p < 0.001; Wilcoxon signed-rank test), as did the proportion of patients in the severely ill group (baseline vs. week 24: 4.1% vs. 2.1%; p < 0.001; McNemar-Bowker test). Conclusion: Continuous 3-monthly paliperidone palmitate treatment significantly enhances the personal and social performance of patients with schizophrenia and reduces the proportion of those with severe illness. These findings suggest that long-acting injectable antipsychotic administration at intervals longer than 1 month might improve the social functioning of and promote return to activities of daily living in patients with schizophrenia.
