In this study, To investigate the antioxidant activities of Rhaponticum uniflorum extracts (RUE), we assessed scavenging activities on DPPH, ABTS radicals, and reducing power. The DPPH and ABTS radical scavenging activities (SC50) of RUE were 96.97±1.19 μg/mL and 31.26±0.13 μ g/mL, respectively, and the reducing power significantly increased dose-dependent manner. To study the antioxidant effecters of RUE in H₂O₂ induced human keratinocytes, expression of Nuclear factor erythroid-2-related factor 2 (Nrf2) and heme oxygenase-1 (HO-1) were determined by Western blot and qRT-PCR. RUE induced the expression of HO-1, a critical target enzyme of Nrf2, in a concentration-dependent manner. The expression of HO- 1 mRNA was also induced in H₂O₂-treated HaCaT cells but no significant difference in the level of HO-1 mRNA was observed. Taken together, these results suggest that RUE may be useful as a potential ingredient for anti-aging products.

It is important to interpret the soil chemical properties in order to effectively manage the farmland. This study was conducted to investigate the soil chemical properties of upland soybean field according to the soil series at 32 upland fields located in the parts of Gangwon-do. Soil sampling sites were selected by using the National Statistics DB and KSIS DB that is a soil environment information system provided by the Rural Development Administration. Soil samples were collected from 0~15 cm of top soil before seeding or transplanting, air-dried, passed through a 2 mm sieve, and analyzed for soil pH, EC, organic matter, available phosphorus (P2O5), exchangeable potassium, exchangeable calcium and exchangeable magnesium. The average chemical properties have exceeded the each nutrient optimum range level of RDA, except the organic matter in experimental soil 2015. And despite application of conventional fertilization, each soil series nutrient contents were change respectively. The results of this study suggest that conventional fertilization should be applied based on the analysis about the amount of accumulated nutrient contents in the soil.

자가치아이식이란 자신의 치아를 구강 내의 한 위치에서 다른 발치와나 외과적으로 형성된 치조와로 이동시키는 술식이다. 통상적으로 이 술식은 상실되거나 보존하기 힘든 제1대구치를 다른 치아로 대체하거나, 매복된 견치를 악궁의 정상 위치로 이동시키거나, 전치부와 같이 심미적으로 중요한 부위의 상실된 치아를 소구치로 대체하는 경우에 많이 사용된다. 자가치아이식을 성공적으로 수행하기 위해서는 세심한 수술 기법과 더불어 적절한 증례 선택이 중요한데, 이식할 치아는 치근 발육이 1/2~3/4 정도 이루어진 미성숙 치아가 유리하고 근단공이 넓을수록 치수 재혈관화의 가능성도 높아져 이후의 근관 치료의 필요성도 줄일 수 있다. 본 증례들은 소아에서 치근단 미완성 치아의 자가치아이식을 통해 임상적, 방사선학적으로 양호한 치유 결과를 얻었고, 별도의 근관 치료 없이 양호한 치수 치유 결과를 보였기에 보고하는 바이다. Autogenous tooth transplantation can be defined as the surgical movement of a tooth from one position in the mouth to another in the same individual. The most common reasons for tooth transplantation include replacement of a missing first molar, transplantation of impacted canines to their normal positions in the arch, and transplantation of premolars in areas of missing teeth, especially in the anterior area of the mouth. The key to successful tooth transplantation is proper selection of graft with adequate root development as well as the design of surgical operation. Root development stage with half to three-quarter-developed roots increase the success rate of autotransplantation. We report the cases of successful autotransplantation which resulted in ideal healing of periodontal ligament, gingiva and alveolar bone. All transplanted teeth presented immature root formation at the moment of the procedure. After surgical procedure, we can observe good healing pattern without endodontic problem.

서현우,김지혁,박호원 大韓小兒齒科學會 2004 大韓小兒齒科學會誌 Vol.31 No.1

Pilomatricoma(Calcifying epithelioma of Malherbe)는 모낭 세포 기원의 양성 연조직 종양으로, 보통 머리와 목 부위에 나타나며, 20세 이전의 여성들에게서 호발하고, 악성으로의 전이가 보고되기도 하나, 이는 극히 드물다. 임상적으로, 무통성, 표재성, 고형성이며 종종 적청색을 나타내고, 크기는 보통 0.5~3.Ocm 정도로 다양하게 나타난다. 조직학적으로, 세포기질 내에 상피조직이 존재하는 형태이며, 상피조직에서는 기저제포(basaloid cell)와 유령세포(ghost cell)가 특징적으로 나타나고, 세포내와 기질내 석회화가 종종 관찰되기도 한다. 진단은, 초진시 고형 물질의 촉진으로 병소를 의심해볼 수 있고, 조직병리학적 검사로 확진할 수 있다. 감별진단으로는 아가미낭(branchial cyst), 혈관종(hemangioma), 횡문근육종(rhabdomyosarcolna), 표피포함낭(epidermal inclusion cyst), 모낭(pilar cyst), 이하선 종양(parotid gland tumor), 피부의 골종(osteomas of the skin) 림프절의 석회화(calcified lymph nodes), 죽종(atheromas) 등이 있다. 치료로는 외과적 절제술이 추천되며 재발은 드물다. 본 증례는 우측 하악각 부위에 결절이 촉진되는 6세 여자 환아에게서 임상 검사와 방사선 검사 후 병소의 외과적 절제술을 시행하였으며, 조직병리학적 검사를 통해 pilomatricoma로 확진되었고, 양호한 치료 결과를 얻었기에 이에 보고하는 바이다. Pilomatricoma is a benign soft tissue tumor of hair follicle origin. They occur most commonly in the head and neck region and are usually found in girls during the first two decades of life. Although malignant transformation has been described, it is exceedingly rare. The clinical presentation is typically that of an asymptomatic, superficial, solitary, firm mass that is often accompanied by a reddish-blue discoloration of the overlying skin. Histopathologically pilomatricoma are seen as epithelial islands embedded in a cellular stroma. The epithelial component consist of two main cell types : basaloid cells and ghost cells. Intracellular and stromal calcification is reported in many cases. Diagnosis is usually suspected based on palpation of a superficial, rock-hard mass and confirmed by histopathologic examination. Surgical excision is both curative and the treatment of choice. Recurrence is rare. In this case, the radiographs showed a dense calcification, measuring about 1cm diameter. So simple excision was performed intraorally, and resultantly the lesion was proved to be a pilomatricoma by histological examination.

본 연구는 보다 효과적인 치료계획 수립과 행동조절을 시행하는데 도움을 얻고자, 1999년 1월 1일부터 2002년 12월 31일까지 강릉대학교 치과병원 소아치과에 내원한 환아를 진료기록부를 통해 조사하고, 진정치료를 받은 환아들 및 보호자의특성을 진료기록부 및 초진시 설문지를 통해 진정치료를 받지 않은 환아들과 비교, 분석하여 다음과 같은 결과를 얻었다. 1 내원 환아수 증가와 함께 진정치료환아들의 수가 1999년부터 2002년의 4년 동안 계속적으로 증가하였다. 2. 진정환아군은 비진정환아군에 비해 어린 연령 대에 집중되어 유의할만한 분포의 차이를 보였다(p<0.001). 3. 월별 내원경향에 있어서 진정환아군은 3, 7, 11월에 높은 비율을 보여 전체 환아에 비해 내원빈도 분포에 유의할 만한 차이를 보였다(p<0.001). 4. 보호자 직업의 분포에서도 추후 계속된 연구가 필요하지만, 진정환아와 비진정환아군 간에 통계적으로 유의한 차이가 있었다(p<0.001). 5. 진정환아군은, 비진정환아군에 비해 예방, 교정적인 치료보다는 충치치료를 주소로 내원하는 비율이 높아 내원동기의 분포에 유의할만한 차이가 있었다(p<0.001). 6. 이전 치과치료시 진정환아군에서 부정적 반응을 보인 비율이 더 높았고, 보호자 기대치에서도 진정환아군에서 부정적반응을 기대한 비율이 더 높았다(p<0.001). 7. 진정환아군의 31.2%는 소개를 통해 소아치과에 내원하였으며, 치과의사에 의한 소개가 가장 높은 58.3%를 차지하였다. 8. 달래도 치료를 거부할 경우, 진정환아군의 보호자들은 50.9%가 진정치료를 선호한 반면, 비진정환아군의 보호자들은 물리적 방법을 54.6%로 선호하여 유의할만한 분포의 차이를 보였다(p<0.001). Recently, many children have been treated under sedation in the department of pediatric dentistry of the dental hospital of Kangnung National University, and sedation cases are increasing gradually. So, in this study, the author analyzed and studied about the characteristics of sedated pediatric dental patients and their parents with patient chart and questionnaire at first visit, from 1999 to 2002 for the purpose of making pediatric dental treatment plan more effective and the improvement of behavior management for better pediatric dentistry. The results were follows : 1. The number of total pediatric and sedative patients increased from 1999 to 2002. 2. The sedated pediatric dental patients were younger than total pediatric dental patients(p<0.001). 3. In visit frequency per month, the sedated patients showed higher percentage on March, July, November contrast to non-sedated patients(p<0.001). 4. In parental occupation, there was a significant difference between sedated patients and non-sedated patients(p<0.001). 5. Caries treatment rather than preventive care or orthodontic treatment, was primarily composed of chief complaint of sedated patients (p<0.001). 6. The sedated patients showed worse response to previous treatment than non-sedated patients, and their parents also expected worse response contrast to non-sedated patients (p<0.001). 7. The patients who were introduced, occupied 31.2% of sedated pediatric dental patients and referral by the dentist were composed of the highest percentage(58.3%). 8. In case of uncooperative child at conventional behavior management. the parents of sedated pediatric dental patients prefered to sedation(50.9%), while the parents of non-sedated patients prefered to physical restraint(54.6%) (p<0.001).

Objectives : This study was conducted to evaluate the reliability and the validity of the Korean version of the Scale to Assessment Unawareness of Mental Disorder (SUMD-K). Methods : The subjects were 55 schizophrenic patients between ages of 26 and 58 who were recruited from the psychiatric unit of the university hospital and the out-patient clinic. The SUMD-K and insight scale of PANSS were applied to the patients. Results : The range of inter-rater (Spearman's rho) of the general items of SUMD-K were .97-.98 on the current illness and .58-.98 on the past illness. The correlation coefficient between the sum and the general items of the SUMD-K showed high scores. The concurrent validity between SUMD-K and insight item of PANSS was high (scores between .59-.96). However,the reliability and the validity of the attribution items of symptoms showed low scores compared to the current symptoms. Conclusion : The SUMD-K was confirmed in its reliability and validity. It can be a useful clinician-rating scale for evaluating insight in schizophrenic patients as well as patients with other neuropsychiatric conditions.
