        Hyun Soo Kim, Jong Woon Cheon, Min Su Kim, Chang Kil Jung, Kyung Rok Kim, Jae Won Choi, Dong Woo Kang and Sun Young Kim1 Departments of Internal Medicine and Pathology1, DongKang Medical Center, Ulsan, Korea Actinomycosis is a chronic suppurative disease and caused by Actinomycosis species, principally Actinomyces israelii, which are part of the normal inhabitant on the mucous membrane of the oropharynx, gastrointestinal tract, and urogenital tract. It usually affects cervicofacial, thoracic and abdominal tissue. Cervicofacial type has the highest percentage of occurrence with 50%. Actinomycosis frequently occurs following dental extraction, jaw surgery, chronic infection or poor oral hygiene. It may also be considered as an opportunistic infection in immunocompromised patients such as malignancy, human immunodeficiency virus infection, diabetes mellitus, steroid usage or alcoholism. But, actinomycosis rarely occurs in adults with normal immunity and rare in the esophagus. We report an unusual case of esophageal actinomycosis which was developed in a patient with normal immunity and improved by therapy with intravenous penicillin G followed oral amoxicillin, and we also reviewed the associated literature.

        In Vitro Antiviral Activity of Ribavirin Against Severe Fever with Thrombocytopenia Syndrome Virus Myung Jin LEE1, Kye-Hyung KIM1, Jongyoun YI2, SuJin CHOI1, Chung-Jong KIM1, Nak- Hyun KIM1, Kyoung-Ho SONG1, Pyoeng Gyun CHOI1, Ji-Hwan BANG1, Wan Beom PARK1, Eu Suk KIM1, Sang-Won PARK1, Hong Bin KIM1, Nam Joong KIM1, Myoung- Don OH1 Seoul National University College of Medicine, Korea1, Pusan National University School of Medicine, Korea2 Background: Severe fever with thrombocytopenia syndrome (SFTS) is an emerging infectious disease caused by a novel Bunyavirus, severe fever with thrombocytopenia syndrome virus (SFTSV). No effective antiviral therapy is proven yet, but clinical use of ribavirin (RBV) has been tried. We investigated the antiviral effect of RBV against SFTSV in vitro. Methods: To test for cytotoxicity of RBV, Vero cells were treated with different concentrations of RBV (3.90 to 500 μg/mL, two-fold dilution) and analyzed by cell viability MTS assay 48h post-infection. To determine antiviral activity of RBV against SFTSV, Vero cells were infected with SFTSV strain Gangwon/Korea/2012 at 100 TCID50 (50% tissue culture infective dose) per well in a 96-well plate, and RBV was added at the concentrations showing no or minimal cytotoxicity. Viral RNAs were extracted from the culture supernatants and quantifi ed using one-step real-time reverse transcription- PCR to amplify the partial large segment of SFTSV. Statistical analysis was done by one-way ANOVA with Tukey`s post hoc test. Results: Cytotoxicity due to RBV was not observed at RBV concentration =31.3 μg/ mL. Viral RNAs at 24h post-RBV treatment were reduced with increasing RBV concentrations (1-32 μg/mL), compared with those of mock-treated cells (P <0.01, Figure). Half maximal inhibitory concentration (IC50) of RBV was 3.69 μg/mL at 24h post-RBV treatment. Conclusions: Our study shows that RBV has antiviral effect against SFTSV in a dose-dependent manner. Further studies are required to evaluate the effi cacy of RBV in SFTS.

        김종현,김성곤,신성현,박제민,김명정 大韓神經精神醫學會 2004 신경정신의학 Vol.43 No.6

        Objectives : We investigated the effects of naltrexone on acute alcohol response, stimulant and sedative, in healthy social drinkers using two doses of alcohol intake. Methods : Twenty four healthy male medical students were voluntarily participated. The experimental method was Cross-over design, Subjects received 25 mg/day or 50 mg/day of naltrexone on the experimental days. Biphasic Alcohol Effects Scale (BAES), alcohol craving, and blood alcohol concentration (BAC) were measured before drinking and at 15, 30, 45, 60, 90,and 120 min after drinking. Results : 1) Group of 0.6 mg/kg of alcohol intake. When the scores of stimulative subscale of BAES were compared bet-ween the naltrexone and control group, the scores were significantly lower in the naltrexone group at 15 and 90 min after drinking. Alcohol induced sedative effect was significantly higher in the naltrexone group at 90 min after drinking. The alcohol induced alcohol craving at 45 and 60 min after drinking was significantly lower in the naltrexone group as compared to the control. 2) Group of 0.3 ing/kg of alcohol intake. The alcohol induced stimulative effect evident in the control group seen in the time span of 15 to 45 min after drinking was not seen in the naltrexone group. The increase of alcohol induced alcohol craving noticed at 30 min after drinking in the control group was not seen in the naltrexone group. BAC at 15 min after drinking was lower in the naltrexone group compared to the control. Conclusion : Naltrexone is suggested to attenuate stimulative effect, to intensify sedative effect, and to block alcohol induced alcohol craving. These triple actions might be utilized for treatment and prevention of relapse of alcohol dependence.

      • 항암제 처리한 백혈병 세포주에서의 Apoptosis 발현

        김삼용,윤소현,김현수,김종숙,윤환중,김진경,조덕연 충남대학교 암연구소 1998 癌共同硏究所 硏究誌 Vol.2 No.1

        The bcl-2 proto-oncogene encodes a 26 kD protein that promotes cell survival by blocking apoptosis. The bax protein is a member of the bcl-2 familly, now known to form heterodimers with the bcl-2 protein. The ratio of bax to bcl-2 is be critical in determining the fate of the cell in response to stimuli that can induce apoptosis. Extract of Pulsatilla Koreana (SB-31) showed promising antitumor activity in vitro with Topo I inhibitory action. In the present study, the relationship between apoptosis and the apoptosis related proteins, bcl-2 and bax were investigated in human leukemic cell lines HL-60, U-937 and CEM-CM3. All anticancer drugs(adriamycin, etoposide, camptothecin, SB-31) induced extensive apoptosis in HL-60, U-937 cells and CEM-CM3 cells. The expression of bcl-2 and bax protein were determined in cell lines by western blotting before and after incubation with anticancer drugs at different time points. 1) In HL-60 or U-937 cell lines, down regulation of bcl-2 and up-regulation of bax were found after incubation with ADR, VP-16 or camptothecin. 2) In HL-60 or U-937 cell lines, no significant change in bcl-2 or bax protein expression resulted after incubation with SB-31. 3) In CEM-CM3 cells, virtually no change was noted in bcl-2/bax expression after incubation with ADR, VP-16, camptothecin or SB-31. It is suggested that different leukemic cell lines use different pathways of apoptosis activation and a given cell may utilize different pathways of apoptosis activation in response to different cytotoxic agents.

        김종달, 남덕현, 이한경, 반종진 용인대학교 체육과학연구소 2000 體育科學硏究論叢 Vol.10 No.1

        This study is for the purpose of examining effects related to duty stress & duty satisfaction due to Police of officers' Physical exercise participation, helping more efficient duty Performance, and positive self-formation. Furthermore, providing basic data that can be helpful to the improvement of police duty. The objects of the study were police officers who were taking part in education program in Police Comprehensive Academy, and the number of police officers who answered the questionnaire is 356 police officers, but data used for real analyzation consist of 300 police officers. The tools for the study were based on Ivancevich's duty stress model in order to measure stress. And also questionnaire used on Kim yoon hee, Kim mae ja, Jo kyung soon, Lee hart kyung's study was used as a complementary tool. The instrument for measuring duty satisfaction rate was developed by Paula. And I used the instrument based on questionnaire that was used by Ko hee soon, Park ki hyung, Kim bum sik, Lee jong kil, Lim bun jang, Jo young chang, Hackeman, Lawlar and Oldham's study. Data analysis is Processed statistically with SPSS/PC+, I Performed T-verification, ANOVA-verification in accordance with the purpose of study after getting the percentage and the real number in case of general characteristics of the objects, and examine an average and standard variation in case of duty satisfaction and duty stress rate. And I set an err rate to 0.5. I verificated co-relation between stress and duty satisfaction with Pearson Correlation Coefficient. The result of the study is as follows, The first, among sociological characteristic and external factor of duty satisfaction, The married is more significant statistically(p< .01, p<.05) compared to the unmarried in terms of compensation system and working condition , which are subfactor of duty satisfaction . In terms of the length of one's service, the longer service term one has the higher significance level one shows in compensation system, working condition, safety, and external factor which are sub-factors of duty satisfaction In terms of an academic background, one who graduated from a high school shows significance statistically only in working condition which is a subfactor of duty satisfaction compared to other people (p<0.5) The second, among sociological characteristic and internal factor of duty satisfaction, the married is more significant statistically(P<.05) compared to the unmarried in terms of achievement which is a subfactor of duty satisfaction. In terms of age the older one shows higher significance level in stability which is a subfactor of duty satisfaction compared to younker one(p<.05) In terms of the length of one's service the longer service term one has ,the higher significance level one shows(p<.01, p<.05). The third, in terms of duty stress due to sociological variable, the married is more significant statistically(p<.05) in case of stress stems from police duty than the unmarried Interms of age, welfare and duty stress are significant statistically(P<.05) Interms of the length of one's service, police's work is significant statistically(P<.05). One who graduated from junior college is significant statistically in police's work, welfare, stress and gets a lot of stress in personal relations(p<.05). The forth, groups participating in exercise are more significant statistically in stability(p<.001), feeling of stability(P<.001), achievement(p<.001), internal factor(p<.01), external factor(p<.05) than croups not Participating in exercise. The fifth, groups participating in exercise are more significant statistically only in personal management than groups not participating in. The sixth co-relation between duty satisfaction and duty stress is r=-0.3814, (P<.001) ,which shows opposite co-relation. so, a result the more stress one has, the lower duty satisfaction he gets.

        매복된 상악 중절치의 교정적 견인을 이용한 치험례 : CASE REPORT

        김종식,김은정,김현정,남순현,김영진 大韓小兒齒科學會 2005 大韓小兒齒科學會誌 Vol.32 No.1

        치아 매복이란 여러 가지 이유로 구강 점막이나 악골내에서 치아가 맹출하지 못하고 있는 상태를 의미한다. 상악 중절치 매복의 원인은 치아종, 과잉치, 공간의 상실, 선행유치의 만기잔존 또는 조기상실, 선행유치의 외상으로 인한 치관이나 치근의 기형, 치배의 이소위치 등이 있다. 매복된 상악 중절치의 경우, 측절치가 빠르게 근심으로 이동하여 공간을 상실하고, 정중선의 변이가 발생하며, 낭종을 형성할 가능성도 있다. 따라서, 매복치의 조기 진단과 그에 따른 적절한 처치가 즉각적으로 이루어져야 한다. 일반적으로 매복의 정도가 심하지 않거나, 각화조직에 의해 매복이 초래된 경우 외과적인 노출만으로도 맹출을 유도할 수 있지만, 외과적인 노출후에 일정기간의 관찰에도 맹출이 되지 않는다거나, 치아의 맹출 방향이 자가 교정될수 없을 정도로 심하게 변위되어 있는 경우, 매복의 위치가 너무 심부에 있는 경우에는 교정적 견인을 시도하는 것이 바람직하다. 본 증례는 매복된 상악 중절치 중 일정기간의 주기적 관찰후 맹출이 기대되지 않았기에, 교정적으로 견인하여 치료하였으며, 치료후 다소의 지견을 얻었기에 보고하는 바이다. A tooth impaction means a state that a tooth does not erupt out of oral mucosa or alveolar bone for many reasons. The reasons for an impaction of the Maxillary central incisor are an odontoma, supernumerary tooth, space loss, prolonged remaining or early loss of a preceding deciduous tooth, abnormalities of crown or root caused by trauma of a deciduous tooth and an ectopic position of a tooth germ. In the case of the impacted maxillary incisor, a rapid mesial movement of a lateral incisor leads a space loss and a midline deviation can be happened. Furthermore, it can cause a cyst. When we treated a patient with an impacted central incisor early, we could see a better prognosis. It means an early diagnosis and an exact treatment are very important. Generally if the impaction is not severe or it is caused by a keratinized covering tissue, a surgical exposure can induce an eruption easily but an orthodontic force is recommended when an eruption does not happen after a surgical method, when the eruption path is too transpositioned to be corrected spontaneously and when an impacted tooth is located so deeply. In the treatment using an orthodontic force, careful considerations about a root length, pulp, and a periodontal tissue can improve the periodontal and esthetic prognosis for the long follow-up results. This case is using an orthodontic traction following a periodic observation and in no expectation of spontaneous eruption. After treatment of this case, I have got some knowledges, so I report this case.
