N/A Minima1 deterioration of cerebral perfusion or microanatomical changes were undetectable on conventional Brain CT or MRI. So evaluation of focal functional changes of the brain parenchyme is essential in chronic head injury patients, who did not show focal anatomical changes on these radiological studies. However, the patients who had longstanding neurologic sequelae following head injury, there had been no available imaging modalities for evaluating these patients precisely. Therefore we tried to detect the focal functional changes on the brain parenchyme using Tc-99m-HMPAO Brain SPECT on the patients of chronic head injuries. Twenty three patients who had suffered from headache, memory dysfunction, personality change and insomnia lasting more than six months following head injury were included in our cases, which showed no anatomical abnormalities on Brain CT or MRI. At first they underwent psychological test whether the symptoms were organic or not. Also we were able to evaluate the cerebral perfusion changes with Tc-99m-HMPAO Brain SPECT in 22 patients among the 23, which five patients were focal and 17 patients were nonfocally diffuse perfusion changes. Thus we can predict the perfusion changes such as local vascular deterioration or functional defects using Tc-99m-HMPAO Brain SPECT in the patients who had suffered from post-traumatic sequelae, which changes were undetectable on Brain CT or MRI.

연구목적 : 본 시험의 목적은 임상시험 시작전에 연구자들을 대상으로 PANSS Workshop을 통하여 PANSS, ESRS에 대한 국내에서의 표준화 작업을 구축하고 새로운 정신병 치료제인 리스페리돈의 효과와 안정성을 재확인하여 리스페리돈 사용에 대한 적정화를 이루는데 있다. 연구방법 : 1996년 4월부터 1996년 9월까지 국내 39개 대학병원 정신과에 입원중인 혹은 증상이 악화되어 입원하는 정신분열병 환자 377명을 대상으로 다시설 개방 연구를 시행하였다. 1주일간의 약물 배설기간을 가진후, 리스페리돈을 8주간 투여하였고, 기준점, 1주, 2주, 4주, 그리고 8주후에 평가되었다. 용량은 제1일에는 리스페리돈 1mg씩 1일 2회, 제2일에는 2mg씩 1일 2회, 제3∼7일에는 3mg씩 1일 2회 투여하였다. 이후 환자의 임상상태에 따라 임의로 증량할 수 있으며, 최대 일일 16mg을 초과하지 않도록 하였다. 추체외로 증상을 조절하기 위한 투약을 허용하였다. 임상증상 및 부작용의 평가는 PANSS(Positive and Negative Syndrome Scale), CGI(Clinical Global Impression) 그리고 ESRS(Extrapyramidal Symptom Rating Scale)을 사용하였다. 연구결과 : 377명중 343명(91%)이 8주간의 연구를 완결하였다. 치료 종결시점인 8주후 PANSS 총점수가 20% 이상 호전된 경우를 약물 반응군으로 정의할때, 약물반응군은 81.3%였다. 리스페리돈에 반응하는 예측인자로는 발병연령, 이전의 입원 횟수, 유병기간이 관련 있었다. 리스페리돈은 1주후부터 PANSS양성, 음성, 및 일반정신병리 점수상에 유의한 호전을 보여 효과가 빨랐다. CGI의 경우도 기준점에 비해 1주후부터 유의한 감소를 나타내었다. ESRS의 경우, 파킨슨 평가점수는 기준점과 비교해 투여 1주, 2주, 4주후 유의하게 증가되었다가 8주후 기준점과 차이가 없었다. Dystonia 평가점수는 1주후만 유의한 증가를 보였으며, dyskinesia 평가점수는 유의한 차이가 없었다. 혈압, 맥박수의 생명징후 및 일반 혈액학 검사, 생화학적 검사, 심전도 검사에서 유의한 변화는 없었다. 결 론 : 이상의 다시설 개방 임상 연구를 통해 리스페리돈은 정신분열병 환자에서 양성증상뿐만 아니라 음성증상 및 전반적인 증상에도 효과적인 것으로 사료된다. 보다 명확한 평가를 위해서는 다른 항정신병약물과의 이중맹검 연구가 필요할 것으로 생각되며, 또한 장기적 치료에 대한 평가도 함께 이루어져야 하겠다. Objective : The purpose of this study was to investigate the efficacy and safety of risperidone in the treatment of Korean schizophrenic patients. Method : This multicenter open study included 377 schizophrenic patients drawn from 39 university hospitals. After a wash-out period of 1 week, the schizophrenic patients were treated with risperidone for 8 weeks and evaluated at 5 points ; at baseline, and 1, 2, 4 and 8 weeks of treatment. The dose was increased from 2mg/day(1mg twice daily) to 6mg/day(3mg twice daily) during the first week and adjusted to a maximum of 16mg/day over the next 7 weeks according to the patient's clinical response. Medication to control extrapyramidal symptoms was permitted. The psychiatric and neurological status of the patients was assessed by PANSS, CGI, and ESRS scales. Results : 343(91%) of 377 patients completed the 8-week trial period. Clinical improvement, as defined by a 20% or more reduction in total PANSS score at end point, was shown by 81.3% of patients. The predictors of response to risperidone were associated older age, shorter duration of illness, fewer previous hospitalization. Risperidone had rapid onset of action ; a significant decrease of the total PANSS and three PANSS factor(positive, negative, general), and CGI was already noticed at the end of first week. For the ESRS, parkinsonism rating scores were significantly increased until week 4 comparing with baseline. Dystonia rating scores were significantly increased until week 1, and dyskinesia rating scores were not significantly changed during the study. Laboratory parameters including vital sign, EKG, hematological, and biochemical values showed no significant changes during the trial. Conclusions : This study suggests that risperidone is generally safe and effective against both the positive and negative symptoms in our group of patients.

Gold Nanoparticles-Based Colorimetric Assay for Cathepsin B Activity and the Efficiency of Its Inhibitors

Kim, Chan-Jin,Lee, Dong-Ik,Kim, Cheonghee,Lee, Kangtaek,Lee, Chang-Ha,Ahn, Ik-Sung American Chemical Society 2014 ANALYTICAL CHEMISTRY - Vol.86 No.8

<P>Cathepsin B has been suggested to be a prognostic marker of melanoma, glioma, and a variety of cancers such as brain, breast, colon, esophageal, gastric, lung, ovarian, and thyroid cancers. Cathepsin B inhibitors have also been considered as anticancer drug candidates; hence, there has been a growing need for a probe which enables the selective and simple detection of cathepsin B and its inhibitors. For the purpose of selective assay, a cathepsin B-specific substrate, <I>N,N</I>′-diBoc-dityrosine-glycine-phenylalanine-3-(methylthio)propylamine (DBDY-Gly-Phe-MTPA) was synthesized in this study. Phe-MTPA, which was produced via cathepsin B-catalyzed hydrolysis of DBDY-Gly-Phe-MTPA, allowed aggregation of gold nanoparticles (AuNPs) leading to a color change from red to blue. When tested for cathepsins B, L, and S, this assay method exhibited AuNPs color change only in reaction to cathepsin B. The limits of detection for cathepsin B was 10 and 5 nM in the 1 and 2 h hydrolysis reactions, respectively. The efficiency of cathepsin B inhibitors such as leupeptin, antipain, and chymostatin was easily compared by the degree of color change. Moreover, IC<SUB>50</SUB> values of leupeptin, antipain, and chymostatin were found to be 0.11, 0.48, and 1.78 μM, respectively, which were similar to the results of previous studies. Therefore the colorimetric assay of cathepsin B and cathepsin B inhibitors using DBDY-Gly-Phe-MTPA and AuNPs allowed not only the selective but also the simple assay of cathepsin B and its inhibitors, which was possible with the naked eye.</P><P><B>Graphic Abstract</B> <IMG SRC='http://pubs.acs.org/appl/literatum/publisher/achs/journals/content/ancham/2014/ancham.2014.86.issue-8/ac4039064/production/images/medium/ac-2013-039064_0009.gif'></P><P><A href='http://pubs.acs.org/doi/suppl/10.1021/ac4039064'>ACS Electronic Supporting Info</A></P>

The objective of this study is to analyze clinical evaluation of 313 patients in Obstetrics and Gynecology who visited Emergency Room in Dankook University Hospital from June, 1994 to December, 1994 for the purpose of successful and perfect emergency care of the patients in Obtetrics and Gynecology in Cheonan-Chungcheong District in the futrure. Today, the goal of modern obstetrics is the well-being of both mother and fetus. And there are many gynecologic diseases which lead the female patient to emergency room with the chief complaint of severe abdominal pain or vaginal bleeding, etc. We have of emergency patients, clinical characteristics of the patients, the time of patient's entrance in emergency room, the monthly distribution of visit, the crowding day of visit, the distribution of the patients according to living area, the admission rate, and the management of the patients, etc. Followings are the results summarized : 1. The mean age was 29.8 years(range form 10 to 85). The mean number of gravidity and parity were 2.0 and 1.1 respectively. The mean number of abortion and living child were 1.0 and 1.0 respectively. 2. The most predominant monthly distribution of visit were August and December. 3. The admission rate was 48.2% and the discharge rate was 49.5%. 4. Distribution of department was Internal Medicine, Pediatrics, Orthopedics, and Obstetrics & Gynecology, in order. 5. The most crowding day of visit was Sunday(22.0%). The peak time of patint's entrance in emergency room was between 20:00 PM and 24:00 PM(24.3%), and the second peak time was between 16:00 PM and 20:00 PM(21.4). 6. Of 313 patients, 53% were known to live in Cheonan city and Cheonan county. 82.7% were known to live in Chungcheong District. 7. In 151 patients who admitted the ward, 53% were obstetric patients and 47% were gynecologic patients. 8. In 80 obstetric patients of admission, the most common chief complaint was labor pain(76.3%). In 71 gynecologic patients of admission, the incidence of disease was abortion(32.3%), ectopic pregnancy(25.4%), and pelvic inflammatory disease(11.3%), in order. 9. Major operations were performed in 40 patients of 151 admitted patients(26.5%). Minor operations including Dilatation and Curettage were performed in 12 patients(7.6%). 10 In 155 patients of discharge, the incidence of disese was abortion(36 patients), pelvic inflammatory disease(20 patients), false labor(15 patients), and uterine bleeding(11 patients), in order.

Korean universities have developed rapidly since its liberation from hapanese rule in 1945. Korean higher education system has contributed to the socio-economic development of the country. However, Korean higher educational system has some problems. One of the problems is its unbalanced development of higher educational institutions between the capital city and other cities. Koreans traditionally regarded highly colleges and universities in the capital city. The government including private foundations have invested large resources in building colleges and universities in cities and providences had been neglected. However, colleges and universities play crucial role in the local, regional development of the country. It is important to raise academic quality of the colleges and universities in non-capital cities. The quality of colleges and universities depended primarily on faculty, finance, etc. Therefore, it is an imperative condition to recruit academically excellent students for the development of colleges and universities in non-capital cities. Three research questions have guided the research. 1) How the college entrants' academic performance has changed. 2) What colleges and universities have utilized admission policy to recruit excellent students. The research has found out the following results. 1) The academic performances of college entrants in non-capital city were lowered in the 1980s. 2) Colleges and universities have emphasized the academic excellence, which is primarily related to research and academic activities of the faculty. 3) High school students and teachers in Pusan city give local university lower rate than what it is The findings suggest that local college and university make sustained, ststematic efforts in order to develop its status among the institutions. The efforts should include short-term and long-term policies : 1) Marketing activities about scholarship programs, graduates' career prospects, facilities, and the faculty etc. 2) Hiring excellent faculty members 3) Strengthening graduates' gaining job 4) furnishing required facilities and making attractive campus 5) Upgrading the quality of academic and research activities

ABSTRACT The discrepancy between centric relation and centric occlusion have a great role on the successful prosthodontic and occlusal treatment. This study was performed to investigate the effect of the discrepancy between centric relation and centric occlusion on condylar guidance inclination and Bennett shift (immediate and progres- sive side shift). Sixteen adults who have physiologically normal occlusion and are free of TMJ dysfunction were selected. The amount of the sagittal CR-CO discrepancy in lower anterior incisor was ob- tained by Saphon Visi-Trainer. The amount of the CR-CO discrepancy in condylar level was measure.d on the individualized corrected tomography. Pantronic survey was performed by using a arbitrary hinge axis according to manufacturer's direction. All subjects were divided into two groups, group I (small) and group II (large), according to the amount of CR-CO discrepancy. At first the amount of the CR-CO discrepancy in condylar level between two gro was compared and then the condylar guidance inclination and Bennett shift be" "si-i two grou -^ were compared and analyzed. The results were as follows; 1. The average CR-CO discrepancy in lower anterior incisors was 0./'in;r: ? . i., 0.49mm anteroposteriorly, and 0.88mm in total. The average CR-CO di lar level was 0.43mm. 2. The CR-CO discrepancy measured on teeth level and condylar level were highly correlate d (p<0.01). 3. The correlation of the condylar position in the glenoid fossa between two groups was not statistically significant. 4. The large CR-CO discrepancy group showed greater amount of Bennett shift ?-nd >,, guidance inclination, but there is no statistical significancy. 5. It seems that the CR-CO discrepancy have greater effect on progressive side shift than ol""r elements of mandibular movements. Keywords: centric occlusion, centric relation, immediate side stuti.
