Fluoxetine is a nontricyclic antidepressant which blocks serotonin reuptake selectively. Its N-demethyl metabolite, norfluoxetine is also selective inhibitor of serotonin uptake. This study was carried out to compare the bioavailability of Myung-in fluoxetine (20 ㎎/cap with that of Prozac?. The bioavailability was conducted on 24 healthy volunteers who received a single dose (80 ㎎) of each drug in the fasting state, in a randomized balanced 2-way crossover design. After dosing, serial blood samples were collected for a period of 48 hours. plasma was analyzed for fluoxetine and norfluoxetine by a sensitive and validated HPLC assay. The major pharmacokinetic parameters (AUC_0-48hr, Cmax, Tmax. AUC_inf.. MRT. T_1/2. Vd and Cl) were clculated from the plasma fluoxetine concentration-time data of each volunteer. The microcomputer program. "WinNonlin' was used for compartmental analysis. A two-compartment model with first-order inpot, first-order output and no lag time was chosen as the most appropriate phamacokinetic model. The data were best described by using a weighting factor of 1/y^2. Though the plasma fluoxetine concentrations of Myung-in fluoxetine were higher than those of Prozac® at all observed time from 7.9% to 16.9% (P<0.05 at 6, 7 and 10 hr), the bioavailability of Myung-in fluoxetine appeared to be bioequivalent with that of Prozac®. There were no statistical significant differences between the two drugs in al pharmacokinetic parameters including AUC_0-48hr of norfluoxetine.

지하매설관 조사는 구조물을 설계하고 시공할 때 매우 중요하기 때문에 정확하게 조사하여야 한다. 지하매설관 조사는 도면획득, 현장확인 및 수정, 수치지도작성의 순으로 이루어진다. 도면획득은 지하매설관을 관리하고 있는 각각의 관공서에서 담당하고 있어 각각의 관공서를 방문하여 도면을 획득하여야 한다. 현장확인 및 수정은 현장에서 각각의 관공서에서 획득한 도면과 실제 현장에 있는 지하매설관의 위치를 비교하는 것이다. 수치지도작성은 기존도면과 현장 조사를 통해서 지하매설관들의 정확한 위치 및 선형을 수치지도상에 중첩하는 작업이다. 부산 지하철 3호선 공사는 3구간로 나누어져서 수행되고 있다. 1구간은 대저동에서 미남교차로까지의 구간이다. 2구간은 미남교차로에서 수영교차로까지의 구간이다. 3구간은 미남교차로에서 기장까지의 구간으로 되어 있다. 본 논문은 부산 지하철 3호선 공사를 위한 지하매설관조사의 작업중 생긴 여러 가지 문제점을 고찰하고, 앞으로의 대안을 제시하는데 그 목적이 있다. Underground facilities must be investigated in the importance of construction safety. The investigation of underground facilities consists of acquisitting map, convicting field and correcting map, and inputting underground facilities to digital map. Maps of underground facilities must be acquired from public offices managing maps. Convicting field and correcting map is to compare map acquired by public officials to positions of field underground facilities. Input of underground facilities to digital map is to overlay accurate position and line acquired by field work on digital map. Third Subway Construction in Pusan is divided 3 sections. First section is from DAEJEDONG to MINAM rotary, second section is from MINAM rotary to SUYOUNG rotary, and third section is from MINAM rotary to JIJANG. The purpose of this study is to investigate problems of underground facilities for Pusan third subway construction. As the results this paper propose a substitute proposal in future.

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.

Distribution of Taste Receptors in Submandibular and von Ebner Salivary Glands

Yong-Ku Jun,Se-Nyun Kim,Cil-Han Lee,Young-Kyung Cho,Ki-Myung Chung,Stephen D. Roper,Kyung-Nyun Kim The Korean Academy of Oral Biology 2008 International Journal of Oral Biology Vol.33 No.1

Taste is a critically important sense for the survival of an organism. However, structure and distribution of taste receptors were only recently investigated. Although expression of the ion channels responsible for the sense of salty taste and acidity was observed in the non-taste cells, receptors for sweet and bitter taste were only identified in taste cells. Salivary glands are involved in the sensing of taste and plays important roles in the transduction of taste. The purpose of this study is to examine whether taste receptors are present in the salivary glands and to provide clues for the investigation of the taste-salivary glands interaction. Using microarray and RT-PCR analyses, the presence of taste receptor mRNAs in the rat von Ebner gland and submandibular gland was confirmed. Type I taste receptors were preferentially expressed in von Ebner gland, whereas type II taste receptors were expressed in both von Ebner gland and submandibular gland. The tastespecific signal tranducing proteins, Gαgustducin and phospholipase C β2, were also detected in both salivary glands by immunohistochemistry. Finally, the activation of the calcium signal in response to bitter taste in the acinar cells was also observed. Taken together, these results suggest that taste receptors are present in the von Ebner gland and submandibular gland and that type II taste receptors are functionally active in both salivary glands.

Poster Session : PS 1464 ; Infectious Diseases : A Case of Brain Abscess Caused by Aggregatibacter Aphrophilus in Korea

Backgrouond: Aggregatibacter aphrophilus (A. aphrophilus) is a gram negative, capnophilic, fermentative, coccobacillus that is occasionally isolated from patients with infective endocarditis. It has also been reported to cause brain abscess, empyema, meningitis, osteomyelitis and joint infection. Herein we report the first case of brain abscess caused by A. aphrophilus in Korea. Case: A 26-year-old man visited hospital for a headache during three weeks. He presented fever, nausea and vomiting for three days. His blood pressure was 108/69 mmHg and his body temperature was 36.9 ℃ at that time. His past medical history was unremarkable. Brain magnetic resonance imaging (MRI) was performed and revealed the 4 cm sized abscess in the frontal lobe with profound perilesional edema and subdural empyema. He received empirical intravenous antibiotic treatment with ceftriaxone 2.0 g every 12 hours, vancomycin 1.0 g every 12 hours and metronidazole 500 mg every 8 hours. On the 4th hospital day, he had decompressive craniectomy and drainage of the abscess. On the 8th hospital day, A. aphrophilus was identified in the culture of abscess. Vancomycin and metronidazole were discontinued and ceftriaxone monotherapy was maintained because it was susceptible to the 3rd generation cephalosporin. On the 11th hospital day, transthoracic echocardiography was performed, but there was no evidence of endocarditis. After a eight-week course of intravenous ceftriaxone therapy, follow-up MRI revealed almost resolved abscess. Intravenous ceftriaxone was changed to oral cefixime 100 mg every 12 hours and he was discharged. He treated with oral cefixime for 12 weeks in outpatient clinic until the complete resolution of brain abscess on MRI.
