<P><B>Purpose</B></P><P>To determine changes in autonomic nervous system activity after treatment in men with lower urinary tract symptoms (LUTS), we evaluated changes in patients' symptoms, uroflowmetry, and heart rate variability (HRV) after treatment with alpha-blockers for 12 weeks.</P><P><B>Materials and Methods</B></P><P>Ninety-five men who had LUTS (International Prostate Symptom Score [IPSS] ≥8) were included in this study. We divided them into two groups on the basis of a low frequency/high frequency (LF/HF) ratio of 1.6. After treatment with Xatral XL (Handok Inc., Korea) 10 mg for 3 months, we rechecked their IPSS, uroflowmetry, HRV and compared these with the baseline measurements.</P><P><B>Results</B></P><P>Fifty-four men were assigned to the low LF/HF group (group A: LF/HF ≤1.6) and 41 men to the high LF/HF group (group B: LF/HF >1.6). At baseline and 12 weeks, none of the parameters differed significantly between the groups except for HF, which is one of the parameters of HRV. IPSS, the IPSS-voiding subscore, and the IPSS-storage subscore decreased and maximal uroflow increased significantly after 12 weeks of treatment. Whereas the baseline LF/HF ratio increased from 0.89±0.407 to 1.80±1.804 after treatment in group A, it decreased from 3.93±5.471 to 1.79±1.153 in group B.</P><P><B>Conclusions</B></P><P>The efficacies of Xatral XL were clear in both groups. We found that the LF/HF ratio in the two groups merged to a value of approximately 1.79 after treatment. We suggest that this could be a clue to the importance of balance in autonomic nervous system activity in men with LUTS.</P>

The results were compared with clinicopathologic parameters, and the prognostic value of <I>DBC1</I> was evaluated by Kaplan-Meier analysis and a multivariate Cox regression model.</P><P><B>Results</B></P><P><I>DBC1</I> expression was significantly decreased in patients with MIBC compared with those diagnosed with NMIBC (p=0.010). Patients with aggressive tumor characteristics had lower <I>DBC1</I> expression levels in NMIBC (each, p<0.05). By multivariate Cox regression analysis, low <I>DBC1</I> expression was a predictor of progression to MIBC (hazard ratio, 7.104; p=0.013). Kaplan-Meier estimates revealed a significant difference in tumor recurrence, progression to MIBC, and cancer-specific survival depending on the level of <I>DBC1</I> expression in NMIBC (log-rank test, each, p<0.05).</P><P><B>Conclusions</B></P><P>The expression of <I>DBC1</I> was associated with tumor aggressiveness, progression to MIBC, and survival in NMIBC. Our results suggest that <I>DBC1</I> expression can be a useful prognostic marker for patients with NMIBC.</P>

Shim Dong-Wook,Shim June-Sung,Lee Seok-Hyung,Lee Keun-Woo The Korean Academy of Prosthodonitics 2004 대한치과보철학회지 Vol.42 No.3

Statement of problem. Glass fiber post is one of recent developments to accommodate esthetic restoration for endodontically treated teeth. This has many advantages over conventional post system in physical properties, esthetic factor, risk of root and restoration fracture, adhesion to core, radiopacity, removal and retrievabilty, biocompatibility and chemical stability. Purpose. This in vitro study was to evaluate the most suitable type of resin core for the glass fiber post through surveying the fracture modes and the maximum load that fractures the tooth. Material and methods. 50 sound maxillary premolars restored with glass fiber posts($ParaPost^{(R)}$ Fiber White) and different types of resin cores(ParaCore, $Z100^{TM}$, $Rebilda^{(R)}$ and $Admira^{(R)}$) were prepared and loaded to faiure in a universal test machine. The maximum fracture load and fracture mode were investigated in the specimens that were restored with resin and those of metal cast and core. With the data, Wilcoxon rank sum test was used to validate the significance between the test groups, and Tukey' s studentized range test was used to check if there is any significant statistical difference between each test group. Every analysis was approved with 95% reliance. Results. On measuring the maximum fracture load of teeth specimens, there was a significant difference between the maximum fracture loads of the tooth specimens. ParaCore showed the highest mean maximum fracture load followed by $Z100^{TM}$. And, the distribution of fracture mode of tooth specimens showed generally Type D, the three parted fracture of the core around the post was mostly seen(62.5%), and specifically, ParaCore showed 90% and $Z100^{TM}$ showed 100% Type D fracture. Conclusion. Referring to the values of maximum fracture load and mean compressive fracture load, ParaCore and $Z100^{TM}$ had high values and are recommended as tooth colored resin core material for glass fiber post. CLINICAL IMPLICATIONS. This study was carried out intending to be of aid in selecting the appropriate resin core for the glass fiber post. The dual cure type composite resin ParaCore and light cure type composite resin $Z100^{TM}$ have good properties and are recommended as tooth colored resin core material for glass fiber post.

목적 : 전체 임신의 약 1%를 차지하고 있는 모성 심 질환이 동반된 임신의 결과에 대해 알아보기 위함이다. 연구 방법 : 1994년부터 2001년까지 최소한 임신 20주 이후에 분만하였으며 모성 심 질환이 동반된 산모의 의무기록을 고찰하였다. 결과 : 심장질환을 동반한 산모는 총 195명으로 224예의 분만이 있었다. 224예의 임신 중 류마티스성 심질환군이 117예 (52.2%), 선천성 심 질환군이 96예 (42.9%)에 해당하였으며, 나머지는 11예로 부정맥, 심근병증, 승모판막 탈출 증후군 등이었다. 임신과 관련된 모성사망은 2예 (0.9%)가 있었으며, 대부분의 산모 (91.9%)가 분만 전, 분만 중, 분만 후의 뉴욕 심장협회 운동기능 평가상 class I, Ⅱ에 해당하였다. 태아의 평균 재태 기간과 출생시의 평균체중은 37.9주와 2883 gm 이었다. 주산기 사망률이 17.9/1000이며, 선천성 기형은 6예로 전체의 2.7%를 차지하였으며, 선천성 심기형의 재발률은 2.1%였다. 결론 : 모성 합병증 및 조산, 저 체중아의 대부분이 뉴욕 심장협회 운동기능 평가상 class Ⅲ, Ⅳ 심 질환 산모군에서 발생하였다. 산모의 운동기능상태 평가가 산모 및 태아의 예후에 중요한 인자라 할 수 있다. Objective : To assess the pregnancy outcomes complicated by maternal heart diseases. Methods : From 1994 to 2001, medical records of pregnant women who had reached at least 20 weeks of gestation with maternal heart diseases were reviewed. Results : 224 deliveries of 195 women were enrolled in this study. In 117 (52.2%) cases the heart diseases were of rheumatic origin, in 96 (42.9%) cases congenital, and the remaining 11 (4.9%) cases were miscellaneous group that included arrhythmia, cardiomyopathy, and mitral valve prolapse. There were 2 (0.9%) cases of maternal death related to pregnancy. Majority (91.9%) were in New York Heart Association functional classes I, Ⅱ before, during, and after delivery. Mean gestational age at birth and birth weight were 37.9 weeks and 2883 gm. Perinatal mortality rate was 17.9/1000 and the rate of congenital malformation was 2.7%. Recurrence risk of neonatal congenital heart disease was 2.1%. Conclusion : Most complications were developed in the pregnancies complicated by maternal heart diseases with New York Heart Association functional classes Ⅲ, Ⅳ. Functional status of the pregnant women is the important risk factor in maternal and fetal outcomes.

목적: 인터넷상에서 위식도역류질환에 대해서 검색되는 웹사이트들이 정확한 의료 정보를 제공하고 있는지 평가하였으며 이를 통해 위식도역류질환에 대한 인터넷 정보의 지향점을 제시하고자 하였다. 대상 및 방법: "위식도역류질환"과 "역류(성) 식도염"을 핵심 단어로 2006년 7월 1일부터 9월 2일까지 7개의 검색엔진에서 검색된 각각 상위 15개 웹사이트(총 108개)를 대상으로 JAMA 핵심기준과 대한소화기 운동학회의 위식도역류질환의 진단, 치료 가이드라인을 참조하여 만든 점검표를 이용해서 평가하였다. 결과: 전체 108개의 사이트 중 개인 병의원의 검색 빈도가 가장 높았고(21.3%) 대부분 환자나 일반인을 대상으로 하고 있었다(87.0%). JAMA 기준에 3개 이상 부합하는 사이트는 11개(9.3%)였고 3개 미만으로 만족시킨 웹사이트보다 정보의 불확실성이 유의하게 더 낮았다(p=0.002). "Heartburn"에 대한 정의는 50%의 웹사이트에서 비교적 정확히 언급되었고 진단 시 초기에 위내시경 검사를 시행한다고 언급한 사이트는 48.1%, 내시경 검사 없이 24시간 pH 검사 등을 초기에 시행한다는 언급은 26.9%, 식도내압 검사나 번스타인 검사, 식도조영술을 일반적으로 시행한다고 언급한 웹사이트는 28.7%였다. 치료에서는 65.7%에서 생활습관 조정을 언급하였고 생활습관 조정 단독만으로 증상 관해를 유도할 수 있다는 웹사이트는 47.2%였다. 치료약물 중 양성자펌프억제제를 언급한 웹사이트는 57.3%였는데 임상적으로 가벼운 경우에 양성자펌프억제제 4주 투여 후 필요 시 투여나 단계적 하향 투여에 대한 언급은 8.3%, 임상적으로 심한 경우에 양성자펌프 억제제 8주 투여 후 지속 투여에 대한 언급은 11.1%의 웹사이트에서 있었다. 결론: 일반인들이 검색엔진을 통하여 접근할 수 있는 인터넷에서 사이트에서 제공되는 위식도역류질환 진단과 치료에 대한 정보는 대부분 기초적인 수준에 머물러 있었고, 구체적인 부분에서는 사이트마다 정보의 양과 내용에서 차이가 많았다. 이는 인터넷에서 정보를 구하고자 하는 환자에게 적지 않은 혼란을 초래할 수 있을 것으로 판단한다. Background/Aims: Internet has become an important source of medical information not only for medical personnels but also for patients. The aim of this study was to evaluate the quality of internet based medical information about ``gastroesophageal reflux`` or ``reflux esophagitis`` in Korea. Methods: The first 15 internet sites using the key words ``gastroesophageal reflux`` or ``reflux esophagitis`` were retrieved from the 7 most frequently used internet search engines. The quality of information from a total of 108 websites was evaluated using a checklist. Results: Among total 108 sites related to ``gastroesophageal reflux`` or ``reflux esophagitis``, fifty-six sites (51.8%) were made by hospitals or clinics and 94 sites (87.0%) were made for patients. Of the 108 sites, eleven web sites (10.1%) had more than three JAMA benchmarks (authorship, references, currency, and disclosure). Higher quality sites (at least three JAMA benchmarks) were less likely to contain inaccurate information than lower quality sites (fewer than three JAMA benchmarks)-3/11 (27.2%) vs. 60/97 (61.9%) (p<0.01). Despite the fact that articles in the literature emphasized an insufficient evidence to support an association between the lifestyle, dietary behaviors, and GERD, such guidelines continue to be recommended as first-line therapy in most websites. Conclusions: Informations about gastroesophageal reflux disease were incomplete in the majority of medical web sites. These would bring about confusion to patients seeking for an information about GERD through the internet. There is a need for better sources in evidence based informations about gastroesophaeal reflux diseases on the web. (Korean J Gastroenterol 2007;49:231-237)

N/A The leiomyoblastoma of the stomach is an unusual smooth muscle tumor, which was first described by Martin and others in 1960. The gastric leiomyoblastoma is similar to the smooth muscle tumor of leiomyosarcoma in gross and composed of round or polygonal cells instead of spindle cells microscopically. Most of these tumors are benign but some tumors behave in malignant manner. The leiomyoblastoma has better prognosis than other smooth muscle tumors. Recently we experenced a case of leiomyoblastoma of the stomach and report with brief review of literatures.

The role of rhFGF-2 soaked polymer membrane for enhancement of guided bone regeneration

Lee, Sang-Hoon,Park, Young-Bum,Moon, Hong-Seok,Shim, June-Sung,Jung, Han-Sung,Kim, Hyung Jun,Chung, Moon-Kyu Informa UK (TaylorFrancis) 2018 Journal of Biomaterials Science. Polymer Edition Vol. No.

<P>The purposes of this study are to confirm the role of Fibroblast Growth Factor-2 (FGF-2) in bone regeneration by adding various concentrations of FGF-2 to the collagen membrane and applying it to the Biphasic Calcium Phosphate (BCP) bone graft site for guided bone regeneration, to explore the potential of collagen membrane as FGF-2 carrier, and to determine the optimum FGF concentration for enhancement of bone regeneration. Four bone defects of 8mm in diameter were created in 18 New Zealand rabbit calvaria. After BCP bone graft, graft material was covered with collagen membranes adding various concentration of FGF-2. The concentration of FGF-2 was set at 1.0, 0.5, 0.1mg/ml, and same amount of saline was used in the control group. To confirm the bone regeneration over time, six New Zealand rabbits were sacrificed each at 2, 4, and 12weeks, and the amounts of new bone and residual bone graft material were analyzed by histologic and histomorphometric analysis. Qualitative analyses are also conducted through immunohistochemistry, Tetrate-resistant acid phosphatase (TRAP) stain and Russell-Movat pentachrome stain. As the healing period increased, the formation of new bone increased and the amount of residual graft material decreased in all experimental groups. Immunohistochemistry, TRAP staining and pentachrome staining further showed that the addition of FGF-2 promoted bone regeneration in all experimental groups. It was also confirmed that polymer collagen membrane can be used as a useful carrier of FGF-2 when enhanced early stage of new bone formation is required.</P>
