To evaluate the differential elects of chlorpromazine, haloperidol, and clozapine on electroencephalographic (EEG) changes, EEG findings were compared in normal, relaxant, and schizophrenic animal models produced with MK-801 by using power spectral EEG analysis. Under pentobarbital anesthesia, the screw electrodes were implanted on the skull over the frontal cortex for EEG recording. The EEG was recorded before and after intraperitoneal administration of clozapine(5mg/kg), chlorpromazine(5mg/kg) and haloperidol(1mg/kg) in rats while awake(the normal group), rats pretreated with a relaxant pancuronium bromide(the relaxant group) and rats pretreated wish MK-801(0.2mg/kg, i.p., the MK-801 group). Spectrum analysis of the EEG was used to calculate the powers of each band (delta 1-4Hz; theta 4-8Hz; alpha 8-l3Hz; beta L 13-21Hz; beta H 21-30Hz; gamma 30-50Hz; and total 1-50Hz). The EEG activity was presented as the log value of the relative band power. In the relaxant group, clozapine increased the activity of the delta, theta and alpha bands. Chlorpromazine increased the activity of the betaL band as well as the delta, theta and alpha bands and it decreased the activity of the gamma band. However, haloperidol did not change the activity of all bands significantly. In the MK-801 group, clozapine increased the activity of the delta and gamma bands and chlorpromazine increased the activity of the delta, betah and gamma bands significantly, Haloperidol increased the activity of the alpha and betaL bands significantly. To evaluate the differential effects of antipsychotics on EEG between the groups, the ratio of power change after a drug as referenced to pre-drug power in each group was calculated and compared between the groups and was represented by star-like display. In the star-like display, clozapine showed the smallest change and caused a slight shift upwards and to the left, chlorpromazine showed irregular changes, haloperidol showed similar increases along each band.

산성강하물의 영향을 받는 대천공단지역과 영향을 받지 않는 청정지역인 대전 계족산 자연휴양림에서 자라는 밤나무(Castanea crenat)의 잎표면에서 서식하는 총세균수, 생존세균수, 종속영양세균수, 내산성세균수를 1996년 8월부터 1997년 8월까지 5회에 걸쳐 조사하였다. 공단지역 잎표면 평균 총세균수, 생존세균수 및 종속영양세균수는 각각 9.9×10^(5) cell/㎠, 1.6×10⁴cell/㎠, 7.1×10³cell/㎠,로서 청정지역에 비하여 각각 1.5배, 2배, 2.6배 정도로 관찰되었다. MPN법으로 측정한 pH 5.6애서의 잎표면 내산성세를수는 공단지역 3.3×10⁴, 청정지역 3.4×10⁴MON/㎠로 거의 같았고, pH 4.0에서의 내산성세균수는 공단지역애서 1.9×10^-(-1)MPN/㎠인 반면 청정지역에서는 전혀 검출되지 않았다. pH 3.0에서의 내산성 잎표면세균수는 공단지역과 청정지역의 잎권 어느 곳에서도 검출되지 않았다. 한편 계절별 잎표면세균수의 분포는 대체로 잎이 나기 시작하여 크기가 가장 작은 5월에 최대를, 그리고 낙엽이 지는 11월에 최소를 나타내었다. 이런 결과는 공단지역의 대기오염물질의 침적이 주변의 식물 잎표면 세균수를 감소시키지는 않으며, 특히 산성강하물의 영향으로 내산성세균수가 증가함을 보여주고 있다. Total, direct viable count, and acid-tolerant epiphytic bacterial population sizes were quantified on leaves of chestnut tree (Castanea crenata S. et Z.) near Taejon Industrial Estate affected by acid precipitation and deposition as well as in the clean natural forest area, Mt. Kyejok, in Taejon city from August 1996 to August 1997. Geometric mean numbers of total, direct viable count, and acid-tolerant epiphytic bacteria were 9.9×10^(5) cell/㎠, 1.6×10^(6)cell/㎠, and 7.1×10³cfu/㎠ respecfvely, being 1.5, 2, and 2.6 times those in the clean area. Acid-to-lerant epiphytic bfcterial numbers at pH 5.6 by MPN method were 3.3×10" in the industrial area, about the same as the number,3.4×104 MPNicni, of the clean area. Acid-tolerant bacterial number at pH 4.0 was 1.9×10^(-1)MPN/㎠ in the industrial area, whereas none was detected in the clean area. Acid-tolerant bacteria at pH 3.0 were not detected at all in the industrial area as well as in the clean area. Epiphytic bacterial population sizes were generally the greatest in May when leaves are emerged and grew but the lowest in November when defoliation occurs. These results showed that air pollutant deposition on leaves did not cause a deuease of epiphytic bacteria at least and acid deposition on leaves did cause an increase of acid-tolerant bacteria.

김준희,백남섭,정훈,김진표,김윤태 龍仁大學校 2001 용인대학교 논문집 Vol.19 No.-

The purpose of this study was to provide basic materials available to establish the recognition of dance sport on status of dance sport as sport for all. For this purpose, this study used th questionnaire research so as to investigate how middle-aged were conscious of dance sport and the level of their participation in dance sport. In conducting the questionnaire research, questionnaires were distributed to 456 middle-aged in Seoul and Kyonggi Province. Based on the study results, the following conclusion was drawn: First, Cognition of the dance sport of those middle-aged women who are currently receiving dance sport training represents for the most part a high response. When viewed from varied social aspects, magazines or books of dance sport are deemed to be short of, and insead cultivation of specialists related to it is considered a prerequisite. And the notion that general cognition of dance sport came enhanced today than in the past might be ascribed to the fact that dance sport was recently taken as an exhibition came at the Sydney Olympics. Second, cognition of the effects and values of dance sport of those middle-aged women who take part in dance sport reflects a positive response on the whole. Their perception indicates that dance sport is conducive to the maintenance and promotion of health. Furthermore, they think that dance sport contributes to the development of culture and simultaneously is of much help to relieving stress, along with the notion taht it is one of the most necessary leisure activities in contemporary society. Third, as a result of having analysed participation into and preference for dance sport of those middle-aged women who take part in dance sport, they do not lapse much time for it, and their dance sport techniques are thought not bo be so mood by their own evaluation. This is presumed to be caused by so lisle time spent for it, and their preference covers dance sport of varied genre musics. Fourth, those middle-aged women who take part in dance sport disclose a very mood response on dance sport socialists.

이호섭,탁희상,신성훈,김양수,남성진,김혜수,박진희,정수현,김성빈,김예나 고신대학교 의과대학 2010 고신대학교 의과대학 학술지 Vol.25 No.1

배경 : 헤르페스바이러스과에는 단순포진 바이러스(HERPES SIMPLEX VIRUS, HSV), 수두대상포진 바이러스 (VARICELLA-ZOSTER VIRUS, VZV), 엡스타인-바 바이러스 (EPSTEIN-BARR VIRUS, EBV), 그리고 거대세포 바이러스 (CYTOMEGALOVIRUS, CMV) 등이 있다. 헤르페스바이러스 감염은 혈액암환자에서 조혈모세포 이식 환자에서 전파 (dissemination), 이차감염, 세균 중복 감염의 심각한 합병증을 일으킬 수 있다. 하지만 항암약물치료를 받는 림파종 환자에서 항 바이러스 약제의 사용 용량과 기간에 대한 concensus는 없다. 헤르페스바이러스 감염에 대한 발생율과 위험인자를 후향성으로 분석하였다. 방법 : 고신대학교 복음 병원에서 1995년 6월부터 2009 년 2월 사이에 새롭게 진단되어 조혈모세포 이식을 받은 전체 58명의 환자들이 후향적으로 현 연구에 등록했다. 헤르페스 바이러스 감염은 임상적 진단, 혈청학적 검사 또는 병리학적 진단에 기초하여 확진한다. 환자들의 특성은 다음과 같다: 평균 연령은 44세 (범위 19-62세)였고 남녀비는 30:28이었다. 등록된 질환은 백혈병 (n=9, 15.5%), 림프종 (n=30, 51.7%), 다발성 골수종 (n=12, 20.7%), 재생불량성 빈혈 (n=6, 10.3%) 그리고 골수이형성증후군 (n=1, 1.7%)이 포함되었다. 결과는 chi-squre test나 independent samples T test를 사용하여 분석되었다. Multivariate analysises에 대해 logistic regression test를 사용하였다. 결과 : 15명의 환자들 (25.9%)에서 조혈모세포 이식후 헤르페스 바이러스 감염이 발생하였다. 조혈모세포 이식 5년간 누적 발생율은 53.9%였다. Univariate analyses에서 헤르페스 바이러스 감염에 대한 유의한 위험 인자는 없었다. 하지만 조혈모세포 이식후 생존 기간(40.18 ± 30.14 months vs 20.06 ± 26.67 months, p=0.018)은 헤르페스 바이러스 감염의 낮은 발병율과 유의한 관련성이 있었다. 이식 편대 숙주질환 (GVHD)의 존재 (37.5% in developed GVHD vs 0% in no GVHD, p=0.200), 동종조혈 모세포 이식에서 면역억제요법의 기간 (15.98 ± 14.02 months vs 6.78 ± 3.67 months, p = 0.374)은 헤르페스 바이러스 감염에 대한 위험인자가 아니었다. 결론 : 조혈모세포 이식 후 생존 기간은 어사이클로비어 예방을 받은 혈액암 환자에서 헤르페스 바이러스 감염의 낮은 발병율과 연관성이 있는 것으로 보인다. 저용량의 어사이클로비어 예방은 헤르페스 바이러스 감염의 고위험군인 조혈모세포 이식을 받은 혈액암 환자에 필요하리라 생각된다. Background : Herpesviridae family includes herpes simplex virus, varicella zoster virus, Epstein-Barr virus, and cytomegalovirus, etc. Herpesviridae viral infection (HVI) can lead to serious complications including dissemination, secondary infection, bacterial superinfection in patients with hematologic malignancy following hematopoietic stem cell transplantation (HSCT). But there was no consensus on the dose and duration of antiviral agents prophylaxis in patients undergoing chemotherapy. We retrospectively analyzed the incidence and the risk factors for HVI. Method : A total of 58 patients who newly diagnosed and received HSCT with prophylaxis of acyclovir at the Kosin University Gospel Hospital, Busan, Korea between June 1995 and February 2009 were enrolled retrospectively in the current study. HVI was confirmed based on clinical diagnosis, serologic test or pathologic diagnosis. The characteristics of the patients were as follows: the median age was 44 years (range 19-62 years) with a female-to-male ratio of 30:28. The enrolled diseases included leukemia (n=9, 15.5%), lymphoma (n=30, 51.7%), multiple myeloma (n=12, 20.7%), aplastic anemia (n=6, 10.3%) and myelodysplastic syndrome (n=1, 1.7%). The results were analyzed using a chi-square test and independent samples T test. For the multivariate analysis, we used logistic regression test. Results : Fifteen patients (25.9%) developed HVI after HSCT. The cumulative incidence of HVI was 53.8% at 5 years after HSCT. In univariate analysis, there was no significant risk factor for HVI. The presence of graft-versus-host disease (GVHD) (37.5% in developed GVHD vs. 0% in no GVHD, p=0.200), duration of immunosuppressive therapy (IST) in allo-SCT (15.98 ± 14.02 months vs. 6.78 ± 3.67 months, p = 0.374) were not risk factors for HVI. Conclusion : The incidence of HVI was similar to that in historical other studies. There was no risk factor associated with development of HVI. Most of the HVI occurred within the first 24 months after transplantation. So long term use of antiviral prophylaxis may be needed to prevention of HVI after HSCT.

목 적 : 본 연구는 직업성 연 폭로근로자에서 연폭로가 남성 생식기계 독성중 성호르몬에 미치는 영향과 그 정도를 평가하고자 시도되었다.방 법 1998년 하반기에 실시한 일반, 특수건강진단자중 경기도 지역 직업성 연 폭로 근로자 33명과 과거 직업력에서 연 폭로가 없었던 사무직 근로자 33명을 연구대상으로 선정하였다. 연의 생물학적지표로는 혈색소, ZPP, 혈중 연, 및 요중 연을 이용하였으며, 성호르몬으로는 LH, FSH, testos-terone, SHBG 및 FTI를 이용하였다. 연 폭로 지표와 성호르몬과의 상관관계를 조사하였다. 결 과 : 연의 생물학적 지표중 혈색소는 폭로군에서 대조군보다 유의하게 낮았으며, ZPP, 혈중 연및 요중 연등은 폭로군에서 대조군보다 유의하게 높았다. 성호르몬에서 FSH, testosterone, SHBG및 FTI는 모두 폭로군에서 대조군보다 낮았으나 통계적 유의성은 없었다. 폭로군의 성호르몬중에서 연령은 FSH 및 FTI, ZPP는 FSH, 혈중 연은testosterone과 유의한 상관관계가 있었다. 대조군에서 연령은 FSH, testosterone, SHBG 및 FTI와 흡연량은 FSH와 유의한 상관관계가 있었다. 연령군별 폭로군과 대조군의 성호르몬 비교에서 30-39세군의 FTI에서 폭로군이 대조군보다 유의하게 낮았으며 그 밖의 호르몬에서는 모두 유의한 차이가 없었다. 결 론 : 연 폭로군의 FSH, Testosterone, SHBG 및 FTI가 대조군에 비교하여 낮았으나 통계적 유의성은 없었다. 그러나 폭로군에서 연의 생물학적 지표와 일부 성호르몬간에 유의한 상관관계를보였으며 이는 본 연구 대상 근로자의 연 폭로 수준이 일부 성호르몬에 영향이 있음을 보여주는 것으로 판단된다. 향후 이에 대한 지속적인 연구가 진행되어 야 할 것이다. Objectives : This study was performed to evaluate the relationship between biological markers of lead exposure and level of sex. hormones in men occupationally exposed to lead. Methods : In this study, 33 male workers who employed at smelting and battery factories were compared with 33 male workers who were not exposed to lead. As biological markers of lead exposure, hemoglobin, ZPP, blood lead and urine lead were measured. As sex hormones, FSH, LH, testosterone, SHBG and FTI were determined. Results : Hemoglobin level was significantly lower in exposed than in nonexposed group. Level of ZPP, blood lead, and urine lead were significantly higher in exposed than in nonexposed group. There was a trend that level of FSH, testosterone, SHBG, and FTI was lower in exposed than in nonexposed group respectively, but there were no statistical significance. In exposed group, FSH level was correlated with age, ZPP, and blood lead; testosterone level was correlated with hemoglobin, blood lead, urine lead, and SHBG ; and FTI level was correlated with age. Conclusions : Level of some sex hormones were lower in exposed than in nonexposed group but there were no statistical significance between the exposed and the nonexposed group. But level of sex hormones were correlated with several biological markers of lead in exposed group. It suggests that occupational lead exposure might affect sex hormones.

저자들은 호흡곤란, 흉부불쾌감, 심계항진 등을 주소로 내원한 환자에서 경흉부 및 경식도 심초음파 검사상 주폐동맥에서 이완기에 전행하는 지속적인 혈류의 흐름을 관찰하고, 관상동맥 조영술을 통해 좌전하행지 중간부위와 우관상동맥 근위부에서 각각 기시하여 공통경로를 이루면서 주폐동맥으로 유입되는 양측성 관상동정맥루를 보이는 드문 1예를 경험하였기에 문헌 고찰과 함께 보고하는 바이다. A coronary arteriovenous fistula is infrequently encountered vascular communication between a coronary artery and a cardiac chamber, a great artery or the vena cava. It is the most common congenital anomaly that can affect coronary perfusion. Bilateral involvement of coronary fistula constitutes an uncommon subgroup of coronary arteriovenous fistulas. A 69 year-old female patient presented with chest discomfort, palpitation, and dyspnea. In the echocardiography, doppler color flow imaging visualized abnormal flow signals with mosaic appearance in the main pulmonary artery during diastolic phase. Coronary angiography revealed arteriovenous fistula arising from the left anterior descending artery and the right coronary artery. Both coronary arteriovenous fistulas drained into the main pulmonary artery. We report a case of bilateral coronary arteriovenous fistula that was confirmed by echocariography and coronary angiography.
