N/A Determmation of the chomosomal constitution of human spermatozoa has been camed out though the human-hamster interspecific in vitro fertilization(IVF) system. In recent years, the introduction of fluorescence in-situ hybridization(FISH) technique has provided an alternative approach to evaluate the cbmmosomal constitution of human spermatozoa. The nuclei of mature spermatozoa are highly condensed with interpmtamine disulphide bridges, therefore the success of FISH on interphase human spermatozoa relies on partial decondensation of the sperm chromatin. In early studies, dithioothreitol(DTT) has been known as an efficient decondensation agent. Since then, several different decondensation methods using D1T have been establisdhed, and in terms of decondensation, we were tried to fix the optimal decondensation protocol using DlT. In our study, the optimal concentration and treatment time were 1-mM and 30 min, respectively. We examined chromosome complements of human sperm to investigate the effect of paternal age on the hequency of nondisjunction in human sperm. We investgated sperm karyotypes ftom two diffaent age groups)28+-0.5, 46+-6), A minimum of 1000 spermatozoa for one patient were analyzed. The mean frequencies of YY, XX, XY, 21-disamy spermatozoa ware 0.04%, 0.45%, 0.40%, 0.45% respectively in young age group and 1.06%, 0.62%, 1.06%, 0.76% in old ages. The mean frequency of disomy spermatozoa was higher in old age poup compare with those of young age group.

송승규,홍미애,오경창,안승인,태미현,신혜정,장진근,차성호,Song, Seung Kyu,Hong, Mi Ae,Oh, Kyung Chang,Ahn, Seung In,Tae, Mi Hyon,Shin, Hye Jung,Chang, Jin Keun,Cha, Sung Ho 대한소아청소년과학회 2002 Clinical and Experimental Pediatrics (CEP) Vol.45 No.8

목 적: A군 베타용혈성 연쇄구균은 급성 인두편도염의 원인이 되는 세균으로 류마티스성 열 및 사구체 신염과 같은 심각한 합병증을 유발할 수 있어 정확한 진단과 치료를 해야 하는 질병이다. A군 연쇄구균성 인두편도염은 증상만으로는 진단하기 어렵고, 가장 좋은 검사방법인 인두배양검사는 시간을 요하는 단점이 있다. 최근에 비교적 검사과정이 간단한 신속항원검사법을 이용할 수 있게 되었다. 이에 저자들은 두 종류의 신속항원검사법의 민감도와 특이도를 알아보고, 일치도를 평가하기 위해 본 연구를 시행하였다. 방 법: 2001년 11월부터 2002년 2월까지 한일병원 소아과 외래를 방문한 환자 중 인두의 발적과 부종, 인두의 삼출물, 인두의 점상 출혈이 있는 61명의 환자를 대상으로 인두배양검사와 신속항원검사를 시행하였다. 신속항원검사법은 BD $LINK2^{TM}$ Strep A(Becton, Dickinson & Company, U.S.A.)와 $QuickVue^{(R)}$ $In-LINK^{TM}$(Quidel Corporation, U.S.A.)를 사용하였다. 결 과 : 1) 61례의 검체 중 22례(36.1%)에서 인두배양검사상 A군 베타용혈성 연쇄구균이 배양되었다. 2) 집락수 1+는 2례(9.1%), 집락수 2+는 1례(4.5%), 집락수 3+는 10례(45.5%), 집락수 4+는 9례(40.9 %)로 배양되었다. 3) 인두배양검사에서 양성으로 나온 환자 중 3세에서 5세 사이가 14례(63.6%)로 본 연구에서 A군 연쇄구균성 인두편도염의 가장 흔한 연령층이었다. 4) 인두배양검사상 양성으로 나온 환자의 임상 증상 및 징후는 발열과 림프절 종대가 각각 18례(81.8%)에서 나타났고, 인두통 16례(72.7%), 구토 11례(50.0%), 성홍열양 피부발진 8례(36.4%), 두통 7례(31.8%), 복통 7례(31.8%), 딸기모양의 혀는 6례(27.7%)에서 관찰되었다. 5) 민감도는 BD $LINK2^{TM}$ Strep A가 81.8%(18례/22례), $QuickVue^{(R)}$ $In-LINK^{TM}$이 77.3%(17례/22례)이었다. 특이도는 BD $LINK2^{TM}$ Strep A가 89.7%(35례/39례), $QuickVue^{(R)}$ $In-LINK^{TM}$이 100%(39례/39례)이었다. 6) 양성 예측도는 BD $LINK2^{TM}$ Strep A가 81.8%, $QuickVue^{(R)}$ $In-Line^{TM}$이 100%이었다. 음성 예측도는 BD $LINK2^{TM}$ Strep A가 89.7%, $QuickVue^{(R)}$ In-Line$^{TM}$이 88.6%이었다. 7) 인두배양검사에 대한 BD $LINK2^{TM}$ Strep A의 k값은 0.72로 일치도 좋음을 보였고, $QuickVue^{(R)}$ $In-Line^{TM}$의 k값은 0.81로 일치도 아주 좋음을 나타냈다. 결 론 : 신속항원검사법인 BD $LINK2^{TM}$ Strep A와 $QuickVue^{(R)}$ $In-LINK^{TM}$은 민감도와 특이도, 일치도가 높을 뿐 아니라 신속하고 간편하게 결과를 알 수 있어서 인두배양검사와 병행하여 급성 인두편도염을 진단하고 치료하는데 많은 도움이 될 수 있을 것으로 사료된다. Purpose : Recently, a number of rapid antigen detection tests have been available to diagnose group A streptococcal pharyngotonsillitis. The purpose of this study was to determine the sensitivity, specificity and consistency of the two rapid antigen detection tests. Methods : Among the patients who visited our clinic from November 2001 to February 2002, 61 patients who had clinical findings of pharyngeal erythema or edema, pharyngeal exudates and soft palatine petechiae were enrolled in our study. A total of 61 patients were tested with rapid antigen detection tests and throat culture. BD $LINK2^{TM}$ Strep A(Becton, Dickinson & Company, U.S.A.) and $QuickVue^{(R)}$ $In-Line^{TM}$(Quidel Corporation, U.S.A.) were selected for rapid antigen detection tests. Results : Of the 61 patients tested, 22 patients were confirmed as group A streptococcal pharyngotonsillitis by throat culture. The BD $LINK2^{TM}$ Strep A had a sensitivity of 81.8% and a specificity 89.7%. The positive and negative predictive values were 81.8% and 89.7%, respectively. The $QuickVue^{(R)}$ $In-Line^{TM}$ had a sensitivity of 77.3% and a specificity of 100%. The positive and negative predictive values were 100% and 88.6%, respectively. The kappa values of BD $LINK2^{TM}$ Strep A and $QuickVue^{(R)}$ $In-Line^{TM}$ were 0.72 and 0.81, respectively. Conclusion : In addition to high sensitivity, specificity and consistency, both kits are easy to use and simple to interpret, and therefore have the potential to be used with backup throat culture for diagnosis of acute pharyngotonsillitis.

Objective : The purpose of this study was to assess the effect of acupuncture treatment for chronic headache patients using power spectrum analysis of the heart rate variability(HRV). Methods : 15 clinical experiment participants were gathered and through a questionnaire patients who experienced headache for more than 4 hours a day and more than 15 days per month were qualified as Chronic Headache patients. Treatment was applied 2 times a weeks for 8 weeks. The acupoints, GV20, HN23, ST8, HN46, TE17, GB20, LI20, LI11, LI14, ST36, and LR3 were stimulated for 20 minutes. The effects of acupuncture treatment were analyzed using power spectrum analysis of the HRV, HRV was recorded before and after acupuncture treatment. Results : HRV before and after treatment was compared after 8 weeks of acupuncture treatment. Increase in mean values of SDNN and RMSSD were observed but the increases were not statistically significants. Increase in mean values of TP, LF and HF were observed but, the increase was significant(p<0.05) only in TP. Conclusions : The results suggest that acupuncture treatment on chronic headache patients can increase the activity of autonomic nervous system. Further use of HRV for quantitative analysis of acupuncture treatment on autonomic nervous system related symptoms is suggested.

Objective : Because the cause and etiology of chronic headache are not yet fully explained, the treatment of this symptom is not simple. In order to study the effectiveness East-West pain treatment on chronic headache, we evaluated its effect of pain alleviation and quality of life improvement on chronic headache patients who were treated with nerve block and acupuncture, and only acupuncture for eight weeks. Methods : 92 clinical experiment participants were gathered and through a questionnaire patients who experienced headache for more than 4 hours a day and more than 15 days per month were qualified as chronic headache patients. The qualified patients were classified into two groups, nerve block and acupuncture group(EW group, n=49) and acupuncture group(E group, n=43). Treatment was applied 2 times a weeks for 8 weeks. The acupoints, GV20, HN23, ST8, HN46, TE17, GB20, LI20, LI11, LI14, ST36, and LR3 were stimulated for 20 minutes. The effects of two groups were analyzed using VAS scores and BPI(Brief Pain Inventory). Results : The VAS and BPI after four weeks of treatment showed significant improvement among two but differences between the three groups was statistically insignificant. The VAS and BPI of the EW group after eight weeks of treatment showed statistically significant improvement compared to the other two groups. Conclusion : The pain treatment for chronic headache might be contributed to improvement of quality of life as well as alleviation of pain of chronic headache patients. It was suggested that the West pain treatment in combination with East pain treatment might be an useful modality to improve the pain and quality of life in chronic headache patients.

Background : The cun measurement System, an essential and convenient method in locating acupoints, has been widely used in the practice of acupuncture. However, traditional cun measurement has been criticized for its lack of reliability. Objectives : The purposes of this study are to determine if one cun measured by the directional methods have a consistency with that of proportional methods and to investigate which factors are related with these differences, especially in forearm. Methods : The distance between the elbow crease and the wrist crease of forearm was compared to a reference value of one cun obtained by the directional method. In this method, one cun is one third of the distance between index finger and Small finger of a subject, measured at proximal interphalangeal joint. In addition, to investigate the factors influencing the differences between these two methods, we measured the height and body weight and calculated body mass index (BMI). Finally we analyzed the factors correlated with these lengths by linear regression test. Results : The results showed that one cun obtained by the directional methods were significantly different from one cun by the proportional methods in forearm. It was demonstrated that the length acquired with the directional method was more correlated with body weight and body mass index, while the length obtained by the proportional method was more correlated with the height.

할리우드의 映畵産業 戰略과 韓國映畵産業의 新 進路

차인태,전평국 경기대학교 1999 論文集 Vol.43 No.1

This paper discusses the American movie industry, represented by Hollywood. and its foreign market strategy and its overall impact on the korean movie industry. Especially, this paper focuses on analyzing the current crisis of the Korea movie industry and developing the possible alternatives or new path for its reinvigoration by comparing the Production, distribution, and promotion system between the movie industries of the two countries. This paper argues that the current world dominance of the American movie industry can be attributed to its economies of scale, mass production, windowing effect through the horizontal and vertical integration among the relevant industries, strong marketing and distribution system, successful creation of derivative industries through the utilization of mass communication, and the export push and price differentiation policy of the American government. In contrast, this paper argues, the Korean movie industry is handicapped by insufficient movie infrastructure, emphasis on import of foreign movies rather than on national production of its own movies, meagerness of movie production capital, absence of the cooperation system or structure among the movie-relevant industries, and non-transparency of capital flowing for movie production. Following these arguments, this paper suggests that establishment of the strong infrastructure, creation of its own new image and brand for Korean movies, aggressive and efficient marketing strategy, and appropriate policy support of the government are necessary for the reinvigoration and development of the Korean movie industry.

Periosteal osteosarcoma is a distinct entity of malignant bone tumor with characteristic clinical, morphological, and histological features within the group of juxtacortical osteosarcoma. Periosteal osteosarcoma is predominantly located in the tubular long bones, and extremely rarely involving the jaws. A case of periosteal osteosarcoma of the right mandible is presented. A 27-year-old woman complained of the gingival swelling and bleeding tendency of the right posterior mandible. Clinical examination revealed a reddish brown strawberry-like swelling on the affected mucosa, which measured 1.5㎝×1.5㎝. The tumor was located on the lingual cortex of the mandible and extended into the surrounding soft tissues. Microscopically, the tumor consisted exclusively of atypical chondroblastic cells with a small osteoblastic area. A minimal bone marrow involvement was noted and the adjacent cortex was free of tumor. These findings suggested that the tumor originated from the periosteal cambium layer, which lies between the periosteal fibrous layer and the cortex of mandible.
