In order to evaluate the efficacy and safety of risperidone, 10 patients with chronic schizophrenia were examined for 8 weeks in a silgle-open study. After the wash-out period of 1 week, risperidone was administered. Efficacy was evaluated by means of Positive and Negative syndrome Scale for Schizophernia(PANSS) and Clinical Global Impression(CGI). Safety assessment included the Extrapyramidal Symptom Rating Scale(ESRS), vital signs, body weight, ECG, and laboratory tests. The results were as follows 1) On the PANSS total score, there was significant improvement of total score after 1 week (P<.05) of administratiom. 2) On the PANSS positive and negative subscal, there were significant improvement of posotive and negative scores after 2 weeks (P<.05) of administration. 3) On the PANSS general psychopatholgy subscals, there were significant improvement of general psychopathologyscores after 1 week (P<.05) of administratiom. 4) On the CGI, there was significant decreasement of clinical impression of severity of schizophrenia score after 2 week (P<.05) of administration. 5) A statistically significant increase in body weight (P<.05) was observed after 8 weeks of administration. 6) EPS reached the peak at the end of the 1st week of administration of risperidone (11.8± 24.25) but they were easily relieved by addition of benztropine and clonazepam. There was not significant change in laboratory tests, vital sign, ECG after 8 weeks of administration. These results suggest that Risperidone is an effective antipsychotics and clinically safe except for increased body weight in chronic schizophrenia.

Chemical Lumbar Sympathetic Block: Comparison of One- Versus Two-needle Techniques Chul-Jun Mun, M.D., Kyu-Jong Lee, M.D., Sang-Gon Lee, M.D., Jong-Il Kim, M.D.^* Jong-Suk Ban, M.D., and Byung-Woo Min, M.D. Department of Anesthesiology, Fatima Hospital, Daegu, Korea ^*Kim Jong Il Pain Clinic, Daegu, Korea Background: It was frequently noticed in the course of performing a two-needle sympathectomy, that satisfactory spread of contrast solution could be produced by injection through only one of the needles. This led to a closer examination of the merits of single-needle technique. Methods: Forty patients were randomized into two groups. Patients in the single-needle group (n = 20) were injected at the second or third lumbar sympathetic ganglia, while patients in the two-needle group (n = 20) were injected at the second and thired lumbar sympathetic ganglia. Lumbar sympathetic blocks were performed using 3 ml of alcohol and the spread of injectate was verified with C-arm fluoroscopy. The indicators of a successful sympathetic block are increasing skin temperature, decreasing pain, and anhidrosis in the distal extremity. Results: The duration of anhidrosis was 12.2 ?? 2.6 months (mean ?? SD) in the single-needle group versus 13.6 ?? 3.6 months (mean << SD) in the two-needle group. Conclusions: As these results were not significantly different from those obtained in patients having considered to be effective for a neurolytic ;i,bar sympathectomy.

Follicular stem cell was assumed as a hair matrix cell. But, recently it was suggested that follicular stem cells were in the bulge portion of outer root sheath of hair follicles, and its proofs were reported. We tried to culture outer root sheath keratinocytes in the bulge portion of human hair follicles, and it would be experimental base for many factors and drugs realated with hair growth and differentiation. The outer root sheath keratinocytes were isolated from plucked human hair follicles, and could be serially passaged for up to 2 times on used biologic feeder cell layer.

李圭寶,孫惠卿,黃基錫 慶北大學校 醫科大學 1982 慶北醫大誌 Vol.23 No.2

1982年 1月부터 1982年 8月사이에 慶北醫大附屬病院 核醫學科에서 甲狀腺製劑(Comthyroid)를 投與받고 있는 患者中 3∼6個月사이에 甲狀腺機能檢査를 比較觀察할 수 있었던 35例를 檢査한 結果 다음과 같은 所見을 얻었다. RAIU檢査는 甲狀腺製劑 投與前에 比하여 6時間値나 24時間値가 모두 有意하게 正常以下로 低下되었으나, 血中 T_3와 T_4 値는 少數例에서 上昇되어있었으나 全體的으로 別 有意한 上昇은 없었다. 臨床的으로 腺腫의 約半數例에서 縮小效果가 있었으며 藥濟服用으로 因한 副作用은 없었다. 甲狀腺腫의 抑制法으로 投與하는 甲狀腺製劑의 效果는 臨床的으로 甲狀腺 hormone의 生體에 對한 影響이나 副作用은 없이 뇌하수체-甲狀腺軸에만 作用하여 甲狀腺機能抑制 또는 腺腫縮小를 招來할 수 있다고 思料된다. In order to evaluate the effects of thyroid hormone preparation upon the thyroid function, authors investigated comparative thyroid function tests including of RAIU, serum T_3, and T_4 before and after Comthyroid therapy from January to August 1982 in 35 cases of nontoxic goiter. RAIU both in 6 hrs and 24 hrs were significantly decreased during medication, whereas serum T_4 and T_3 showed no appreciable change. There was no case of side reaction from the regimen, however size of goiter seemed regressed more or less in more than half of the cases.

인터넷은 디지탈 형태의 다양한 정보를 신속하게 전달한다는 점에서 매우 각광을 받고 있다. 그러나, 대량의 인터넷 정보 중에서 자신이 원하는 정보 자원을 정확하게 많이 얻어 낼 수 있는 방법의 제공은 매우 어려운 문제이다. 본 논문에서는 인터넷 정보 자원의 메타데이타를 관리하기 위해 SeriCore라는 SGML 형식의 메타데이타 DTD(Document Type Definition)를 정의하고, 이들 메타데이타를 효율적으로 저장하고 검색, 관리할 수 있는 시스템을 설계, 구현하였다 The Internet has gained popularity because ot provides various information in digital format. However, it is very difficult to provide methods which make it possible to search adequate information resource from bulk of Internet information. In this paper, we define a SGML metadata DTD, named SeriCore, and design and implement a metadata retrieval and management system which can store, retrieve and manage the Internet metadata efficiently

움직임 보상을 통한 움직임 기반의 디인테레이싱 기법

이성규,강석규,이동호 漢陽大學校 工學技術硏究所 2001 工學技術論文集 Vol.10 No.-

본 논문에서는 움직임 보상을 이용한 움직임 기반의 디인터레이싱 알고리즘을 제안한다. 정확한 움직임 추정을 위해 전처 리로서 EBMF(Edge Based Median Filter)를 사용하며 2 개의 같은 위상을 갖는 필드와 1개의 다른 위상을 갖는 필드를 이용한 새로운 BMA(Block Matching Algorithm) 움직임 보상 방법을 제안한다. 시간축 필터로서 모션 미싱 에러를 제거하기 위해 입력 영상의 움직임 영역에 따라 각각 다른 임계값을 적용하는 AMPDF(Adaptive Minimum Pixel Difference filter)를 적용하였으며 MMD(Maximum Motion Detection)와 SAD(Sum of Difference)를 이용하여 빠른 움직임 영역에서 화질을 향상시켰다. 최종적으로 잘못된 움직임 보상에 기인하는 화질의 열화를 방지하기 위한 후처리로서 움직임 보정 필터를 제안한다. 모의 실험을 통해 제안하는 방법이 기존의 방법에 비해 우수한 성능을 갖는 것을 확인하였다. In this paper, we propose a motion-adaptive de-interlacing method using motion compensated interpolation. In a conventional motion compensated method, a simple pre-filter such as line averaging is applied to interpolate missing lines before the motion estimation. However, this method causes interpolation error because of inaccurate motion estimation and compensation. In the proposed method, EBMF(Edge Based Median Filter) as a pre-filter is applied, and new matching method, which uses two same-parity fields and opposite-parity field as a reference, is proposed. For further improvement, motion correction filter is proposed to reduce the interpolation error caused by incorrect motion. Simulation results showed that the proposed method provides better performance than existing methods.

Although it is known that hypothyroidism can cause cardiac dysfunction, it is very hard to find a case report on sudden death due to hypothyroidism. There are only two reported cases on mediline; one is about a 15-year-old girl who died suddenly of Hashimoto's thyroiditis and the other is about a 31-year-old man who also died suddenly of hypothyroidism associated with chronic lymphocytic thyroiditis. Recently we found a young woman who unexpectedly died while she was sleeping. She was diagnosed as hypothyroidism when she went to hospital about a month before she died. At autopsy there were roughly four abnormal findings; Hashimoto's thyroiditis, mild chronic active hepatitis, diverticulosis and accessory spleen. Trace of chlorpheniramine was detected in gastric remains and blood alcohol level was 0.37 percent. To our knowledge, this is the first case reporting sudden and unexpected natural death associated with hypothyroidism in Korea.

이민하,양규호,오종석 전남대학교 치과대학 2000 전남치대논문집 Vol.12 No.1

Streptococcus salivarius is a normal inhabitant in the human oral cavity. Streptococcus salivarius 119 in this study was isolated from the oral cavity of child and identified, and its action mechanism on the formation of denal plaque by Streptococcus mutans was studied. 1. The optical density of absorbance at 550 nm was 0.327 in the culture of Streptococcus mutans in disposable cuvette, whereas being 0.119 in the combined culture of Streptococcus mutans and Streptococcus salivarius 119. 2. The mean weight of produced artificial plaque on the wires in the beaker was 84.7mg in culture of Streptococcus mutans only, whereas being reduced to 12.3 mg in the combined culture of Streptococcus mutans and Streptococcus salivarius 119. 3. When Streptococcus mutans was cultured in the media containing culture supernatant of Streptococcus salivarius 119 in BHI broth, the mean weight of produced artificial plaque was 100.5 mg on the wires, whereas being reduced to 20.4 mg in the media containing culture supernatant of Streptococcus salivarius 119 in BHIS broth. 4. The viable cells of Streptococcus oralis and Streptococcus salivarius 119 were 4.8×10^7 and 7.5×108 per ml respectively after each culture, wheras being 4.2×10^7 and 5.8×10^7 per ml in the combined culture of Streptococcus oralis and Streptococcus salivarius 119. 5. The polymer produced by Streptococcus salivarius 119 was glucan on the thin layer chromatography. 6. The glucan produced by Streptococcus salivarius 119 was water-soluble glucan containing 1→6 linkages as the main linkage on the thin layer chromatography. These results suggested that isolated Streptococcus salivarius 119 inhibited the formation of artificial plaque by the production of water-soluble glucan.
