Silver Nitrate溶液의 精巢內 注射에 衣한 家兎의 去勢效果에 關한 硏究

金鐘洙,趙聖均,李殷奉 順天大學校 1984 論文集 Vol.3 No.1

This experiment was carried out to develop a Chemical castration with a single intratesticular injection of silver nitrate solution in domestic rabbits. A total of 44 bucks of 4 to 5 months old were alloted at random into the following 4 groups; 9 bucks for controls; 6 bucks for 0.3㎖ injection of 1% AgNO₃to each testis; 14 bucks for 0.5㎖ injection of 1% AgNO₃: and 15 bucks for 0.5㎖ injection of 5% AgNO₃. Changes in body weight, testicuar width in scrotum sac, weight and histology of testis at slaughter, blood cell counts and serum levels of testosterone of the buck were measured for 4 weeks after treatment. The results obtained were summarized as follows: 1. Compared with the controls the body weght gain of bucks treated with AgNO₃was not significantly (P<0.05) different during the experimental period for 4 weeks. 2. The white blood cell counts were increased slightly but insignificantly 1 day after injection of AgNO₃and then decreased to normal level soon. There was no significant change in red blood cell counts in the bucks treated with AgNO₃. 3. Most of the testis of bucks were swollen significantly (P<0.05) by 6 to 12㎜ in the width of testis in scrotum sac 1 day after injection of AgNO₃, but decreased in size 3 days after treatment and regained their normal size in a week. 4. The AgNO₃injection was not sufficient for same bucks to be successfully castrated. Only 60.0 to 66.7% of the bucks treated with 0.5㎖ dose of 1 to 5% AgNO₃showed the serum level of testosterone of lower than 0.1ng/㎖ by 28 days after treatment. This was considered to be resulted from the fact that not a whole but a limited part of testis injured by this scheme of injection. 5. The weight of testis of the bucks showing less than 0.1ng/㎖ of serum testosterone by 7 to 28 days after treatment was not significantly (p<0.05) different between the treatments of periods after treatment. This result indicates that the period of 4 weeks might be not sufficient for the injured testicular tissue to be necrotized and absorbed. 6. The extent of damage of testis by injection of AgNO₃was much different by the local effect in the parts of distance from injection. A proximal portion of testis injected with AgNO₃was fully damaged and necrotized, but a distal part of testis was not severely damaged.

관엽식물의 잎모양, 크기, 수형에 따른 시각적 인식이 뇌파변화 및 이미지 평가에 미치는 영향

송종은,엄수진,김수연,손기철,이종섭 충북대학교 첨단원예기술개발연구센터 1999 연구보고서 Vol.4 No.-

실내 환경내에서 관엽식물의 보다 효과적인 이용과 시각, 심리환경 스트레스 경감을 목적으로 관엽식물의 형태적 특성이 인간의 정신생리와 심리에 미치는 영향을 알아보고자 잎모양이 다른 아로우카리아(Araucaria excelsa)와 벤자민고무나무(Ficus benjamina), 잎크기가 다른 네프로네피스(Nephrolephis exaltata)와 스킨답서스(Scindapsus aureas), 그리고 수형이 다른 관음죽(Rhapis humilis)과 아레카야자(Chrysalidocarpus lutescens)를 선정하여 각 식물당 남녀 24명 총 72명을 대상으로 뇌파(Computerized EEG)검사, 혈압, 맥박, 시각이미지 평가를 시행하였다. 각 식물에 따른 뇌파를 비교한 결과 뚜렷한 차이를 보이지 않아 관엽식물의 관상에서 잎의 모양, 크기 및 수형이 있는 상태에서 모두 유의한 감소를 보여 스트레스 감소 효과와 안정 효과를 보인 것으로 나타났다. 그러나 각 식물간에는 유의한 차이는 없었다. 이러한 사실은 기존 연구에서 보여준 결과인 식물의 녹색에 대한 정신생리적 반응과 녹(綠)면적에 의한 뇌파변화는 인정되었지만 식물종류에 따른 반응은 중요하게 작용하지 않는 것으로 보여진다. 관엽식물에 대한 이미지는 평가는 4개의 요인 심미성, 청량감, 안정성, 질감성 인자로 구성되었다. 각 인자에 대한 식물종류간에 차이를 조사한 결과 서로 다른 특성을 보였으나 4인자인 질감성 차원에서는 차이가 없었다 이는 의식적으로 인식되는 시각적 이미지 평가요소에서 제 1인자인 심미성과 제 2인자인 청량성이 더 중요하게 작용되는 것으로 판단되었다. 앞으로 보다 명확한 효과를 검정하기 위해 녹시율(綠視率)과 여러 식물 종류를 조합한 좀 더 세밀한 비교와 함께 시간흐름에 따른 뇌파비교를 동시에 조사 분석하는 것이 필요한 것으로 판단된다.

권은경,김은숙,곽주석,이황,이수종,임미경 大韓齒科保存學會 2002 Restorative Dentistry & Endodontics Vol.27 No.1

Black-pigmented bacteria have been implicated in the endodontic infections. This group of microorganisms includes Porphyromonass endodontalis, Porphyromonas gingicalis, Prevotella intermedia, and Prevotella nigresceus. The organisms display a wide variety of virulence factors that may be pertinent to acute endodontic infections. The aim of this study was to identify P.endodontalis, P.gingivalis, P.intermedia, and P.nigrescens by using special potency disk test, filter paper spot test, 16S rRNA gene-directed PCR, and API 32A. Microbial samples were collected from root canals of 33 intact teeth with necrotic pulp and/or apical periodontitis. Conventional laboratory methods were used for identification of the strains of black pigmented bacteria. Eighteen of 33 samples were positive for the growth of black-pigmented bacteria. Five colonies were cultured from each pure cultured colonies from Brucella agar plate. Seventy seven colonies were positive for the growth of black-pigmented bacteria. Thirty three of 77(42.6%) were identifed as P.nigrescens, 10 of 77(12.9%) were P.gingivalis, 6 of 77(7.8%) were P.endodontalis, 10 of 77(12.9%) were P.intermedia. On the contraty the reference strains of P.nigrescens, experimental strains of P.nigrescens was sensitive to kanamycin in special potency disk test. 16S rRNA gene PCR and API test after rapid presumptative identification methods. such as special potency disk test and filter paper spot test, would be accurate detection methods for black-pigmented bacteria.

Fibrothecoma are mesenchymal tumors deriving from the ovarian stroma and consisting of theca-like elements and fibrous tissues. The reported incidence is between 0.4 and 8.0% of all ovarian tumors and this side variability can be attributed to the difficulty in differentiation fibrothecoma from ovarian fibroma or hyperplastic stroma nodules. We experienced a rare case of ovarian fibrothecoma in woman at 38 weeks gestation with previous repeat cesarean section diagnosed after tertiary cesarean delivery and bilateral tubal ligation with a brief review of literature.

박수은,정혜선,곽영호,이환종 대한화학요법학회 1998 대한화학요법학회지 Vol.16 No.3

목적 : cefteram은 새로이 개발된 경구용 세펨계 항균제로서 종래의 세펨계 항균제와 비교하여 β-lactamase에 안정적이다. 저자들은 소아의 호흡기 감염의 주요 원인균인 group A streptococcus, Haemophilus influenzae, Streptococcus pneumoniae의 국내 분리 균주를 대상으로 하며 cefteram의 항균력을 다른 페니실린계 및 세펨계 항균제와 비교하였다. 방법 : 서울대학교 소아병원에서 각종 감체로부터 분리된 group A streptococcus 29주, H. influenzae 53주 (β-lactamase 음성 23주, 양성 30주) 및 S. pneumoniae 93주를 (페니실린 감수성 및 중등도 각각 21주, 내성 51주) 대상으로 하여, cefteram, penicillin 또는 ampicillin, ampicillin/sulbactam, cefaclor, cefuroxime, cefixime, cefpodoxime 및 ceftriaxone 등의 항균제의 최소 억제 농도(MIC)를 한천희석법의로 측정하였다. 항균제 감수성 검사 결과는 MIC 범위, MUC_(50) 및 MUC_(30)으로 나타내었다. 결과 1. Group A streptococcus에 대한 cefteram의 MIC 범위는 <0.015-0.015 ㎍/mL이었고, MIC_(50) 및 MIC_(90)은 모두 0.008 ㎍/mL으로서 검사한 항균제 중 가장 낮았다. 2. β-lactamase 음성인 H. inflenzae에 대한 cefteram의 MIC 범위는 <0.015-0.06 ㎍/mL 였으며, MIC_(50) 및 MIC_(90)은 각각 0.015 ㎍/mL , 0.03㎍/mL 로 ampicillin, cefaclor, cefuroxime보다 낮았으며, cefixime과는 비슷하였다. β-lactamase 양성인 균주에 대한 MIC 범위는 <0.015-0.125㎍/mL , MIC_(50) 및 MIC_(90)은 각각 0.015 ㎍/mL , 0.06㎍/mL 로 amplicillin/sulbactam, cefaclor, cefuroxime보다 우수한 항균력을 보였고, cefixime과는 비슷한 항균력을 나타내었다. 3. 페니실린 감수성 S. pneumoniae에 대한 cefteram의 MIC 범위는 ≤0.015-0.03 ㎍/mL 으로 매우 낮았다. 페니실린 중등도 내성주에 대해서, MIC_(50)이 cefteram 외의 각 항균제들은 0.125㎍/mL 이상이었으나 cefteram은 0.06㎍/mL 으로서 매우 낮았으며, MIC_(50)는 모두 0.25㎍/mL 이상이었으며 cefteram은 0.25㎍/mL 로서 비교적 낮은 값을 보였다. 페니실린 고도 내성균주에 대해서는 검사한 항균제의 MIC가 모두 0.5㎍/mL 이상이었으며, cefteram의 MIC 범위, MIC_(50) 및 MIC_(90)는 각각 0.5- >64㎍/mL , 1㎍/mL 및 4㎍/mL 이었다. Background : Cefteram is an orally administered aminothiazolyl iminomethoxy cephalosporin. I t has been reported to be highly active against group A streptococcus, Haemophilus influenzae and Streptococcus pneumoniae. However, there is a wide geographic variation in the prevalence of antimicrobial resistance, and antimicrobials should be evaluated against isolates from each of particular community where they are going to be used. Methods : Minimum inhibitory concentrations (MIC) of cefteram, penicillin or ampicillin, ampicillin/sulbactam, cefaclor, cefuroxime, cefixime, cefpodoxime, and ceftriaxone were determined by agar dilution method against 29 strains of group A streptococcus, 53 of H. influenzae and 93 of S. pneumoniae, isolated at the Seoul National Umversity Children's Hospital. The results of susceptibility test were presented by MIC range, MIC?? and MIC??. Results : 1. MIC range of cefteram against group A streptococcus was <0.015-0.015 ㎍/mL. MIC?? and MIC?? of cefteram were the lowest among the antimicrobials tested. 2. MIC ranges of cefteram against β-lactamase negative and plactamase positive H. influenzae were <0.015-0.06 ㎍/mL, and <0.015-0.125 ㎍/mL., respectnely. Cefteram was more active against β-lactamase positive H, infuenzae than amplilin/sulbactam, cefaclor, cefuroxime, and comparable with ceftriaxone, cefixime or cepfodoxime. 3. Cefteram had the lowest MIC?? and MIC?? against penicillin susceptible (0.008 ,㎍/mL and 0.015 ㎍/mL ) and intermediate S. pneumoniae (0.06 ㎍/mL and 0.25 ug/ml), but had rather high MIC?? and MIC?? (1 ,ug/mL and 4 ,㎍/mL) against penicillin resistank strains as other oral cephalosporins. Conclusion : The results indicate that cefteram has in vitro activity against group A streptococcus, H. influenzae and S. pneumoniae equal to or higher than other oral antimicrobials tested.

Enantiomeric separation of naproxen is necessary in drug evaluation processes as the pharmacological activity of naproxen resides mainly in the (S)-enantiomer, The enantioseparation of naproxen was carried out with three different stationary phases. The methods were validated with the terms of linearity, intraday and interday precision, accuracy, selectivity and recovery. Among the selected stationary phases, ChiroSil DMB column with hexane : t-butylmethylether : acetic acid (60:40:0.1, v/v/v) as mobile phase showed the best enantioseparation of the naproxen in the commercial preparations. The wavelength for detection was 270 nm and flow rate was 2.0 mL/min. The contents of (S)-naproxen in the commercial preparations were 92.7 - 98.3%, indicating that all tested preparations were satisfactory to current regulation. However, the contents of (R)-naproxen as impurity in the commercial preparations were varied from 0.08% to 1.08%.
