경상북도 영덕군의 하천에 서식하는 점몰개 spotted barbel gudgeon (Squalidus multimaculatus Hosoya et Jeon)의 근육에서 새인두흡충 Clinostomum complanatum (Rudolphi, 1814)의 피낭유충이 발견되었다. 감염된 점몰개는 "yellow grub"인 기생충의 피낭유충으로 인해 표면이 울퉁불퉁하게 보였으며, 수면위에 힘없이 유영하였고 일부 폐사한 개체도 발견되었다. 분리된 탈낭유충의 형태는 혓바닥 모양이었으며, 크기는 2.85~5.89 mm×0.8~1.99 mm였다. 어체당 1~98 개의 피낭유충을 분리하였으며 평균 감염수는 25개로 나타났다. 특히, 성어크기인 평균 7 cm 정도의 점몰개는 100% 감염되어 있었다. 본 연구는 한국의 자연수계에 서식하는 어류에서 C. complanatum 의해 질병이 발생하고 폐사가 일어난 첫 보고이다. The metacercariae of Clinostomum complanatum (Rudolphi, 1814) were isolated in the whole body muscle of wild freshwater fish, spotted barbel gudgeon (Squalidus multimaculatus Hosoya et Jeon) from the local river in Yeongdeok, Gyeongsangbuk-do, Korea. The infected fish with bumpy body surface by "yellow grub" showed erratic swimming behavior and some fish were died. The isolated excysted metacercariae were tongue shaped and 2.85~5.89 mm × 0.8~1.99 mm in size. 1~98 metacercariae were isolated in individual fish and mean infection intensity was 25. All examined adult spotted barbel gudgeon sizing 7 cm in body length were infected. This is the first report of disease outbreak and mortality caused by C. complanatum infection in wild freshwater fish in Korea.

전의찬,우정헌 東新大學校 1996 論文集 Vol.8 No.-
Due to the rapid economic development for the last 20 years, Asian countries' fuel consumption has doubled twice every twelve years. Also, serious environmental problems, especially air pollution, have followed rapid urbanization and development in Northeast Asia, where Korea is located. The pattern of long range transport of air pollutants was investigated in the Northeast Asia region. The focus of this study was the impact of air pollutants from China on the air quality of Korea. From the meteorological data from the 1st to the 5th of January 1995, the backward and forward trajectories were calculated using the Hybrid model 'HY-SPLIT', and the contributions of air pollutants from cities of China to the air quality in Korea were analyzed. It was concluded that the air pollutants from China could have a great influence on the air quality in Korea. The trajectories showed that the air pollutants from Beijing and Jinan, Shandong Province, the most heavily industrialized areas in China, could be influenced strongly to the air quality in Korea.

반유통형의 초임계유체 염색장치를 사용하여 333.2K, 373.2K, 413.2K의 일정온도와 150bar-300bar의 압력에서 이산화탄소에 분산염료를 용해하여 폴리에스터 직물을 염색하고 염색시간에 따른 염착량을 측정하였다. 같은 방법으로 HFC-134a를 사용하여 383.2K와 413.2K의 일정온도와 50bar-160bar의 압력에서 염료를 용해하여 염색을 실시하고 염색시간에 대한 염착량을 측정하였다. 염착랑에 대한 초임계유체의 온도와 압력의 영향이 검토되었다. 이산화탄소와 HFC-134a의 초임계 용매를 비교하기 위하여 두 용매에 대한 염료의 용해도와 평형염착량의 관계를 검토하였다. 동일한 온도에서 HFC-134a를 초임계유체로 사용할 때보다 이산화탄소를 사용하는 것이 큰 평형염착량을 나타내었다. HFC-134a에 대한 염료의 용해도는 이산화탄소보다 훨씬 크지만 직물을 염색하는 초임계용매는 이산화탄소가 더 유리하였다. The uptake of disperse dye into polyester fiber in supercritical carbon dioxide was measured in the pressure range between 150 bar and 300 bar at each temperature of 333.3K, 373.2K and 413.2K, and the uptake in supercritical HFC-134a was measured in the pressure range between 50 bar and 160 bar at each temperature of 383.2K, 413.2K, using a flow-type apparatus with a cylindrical dyeing vessel. The effect of dye uptake in supercritical fluids on temperature and pressure was investigated. The dye uptake at constant pressure was much increased with temperature than it did with the pressure at constant temperature. The equilibrium uptakes of disperse dye in supercritical carbon dioxide were compared with those in the supercritical HFC-134a. The equilibrium uptakes in the supercritical carbon dioxide were much great than those in the HFC-134a at the same temperature. The supercritical carbon dioxide is better supercritical media than the HFC-134a, even though dye in the supercritical HFC-134a is much solved than in the supercritical carbon dioxide.

The lyophilization of the solution extracted from 60 percent of acetone applied to persimmon leaves, the compounding process in accordance with the solution's concentration, and the gel filteration through Sephadex G-50 of biologically activated substances obstructing enzyme activity, such as tyrosinase, xanthine oxidase, and angiotesin converting enzyme (ACE) led to the assumption that polyphenol was the compound serving as biologically activated substances obstructing enzyme activity. Xanthine oxidase involved in pruine metabolism oxidizes hypoxanthine to xanthine and xanthine to uric acid. In the continuous study for natural compound, nine flavan-3-ois have been isolated from the persimmon leaves. The structures of (+)-catechin, (+)-gallocatechin, procyanidin B-1, pyrocyanidin C-1, prodelphinidin B-3, gallocatechin-(4α→8)-catechin, procyanidin B-7-3-O-gallate, procyanidin C-1-3'-3''-3'''-O-trigallate and (-)-epigallocatechin-(4β→8)-epigallocatechin-(4β→8)-catechin were established by NMR and their inhibitory effect on xanthine oxidase activity was investigated. Procyanidin C-1-3'-3''-3'''-O-trigallate showed 94%, 90.69%, 80.90% inhibition at 100(μ)M and inhibited on the angiotension converting enzyme respectively. Procyanidin B-7-3-O-gallate and procyanidin 1-3'-3''-3'''-O-trigallate showed 66%, 63% inhibition at 100(μ)M and inhibited on the xanthine oxidase competitively. Procyanidin C-1-3'-3''-3'''-O-trigallate showed 70% inhibition at 100(μ)M inhibited on the thyrosinase competitively.

Coronary stent implacement is known as an effective treatment in the intimal dissection after percutaneous transluminal coronary angioplasty and the prevention of restenosis. However, In-stent restenosis still remains a major concern in clinical stenting. The stents were placed in 103 patients from July 1996 to March 1999 and performed follow-up coronary angiograms in 59(57.3%) patients. To identify the clinical, angiographic and procedurerelated variables 'which predict late restenosis within the stented artery, 59 patients(58.3±9.9, M:F= 41:18) were studied. The clinical characteristics of the patients were stable angina in 23(39.0%), unstable angina in 14(23.7%), acute myocardial infarction in 21(35.6%) and old myocardial infarction in 1(1.7%). Coronary stenting was performed in 1 patient(1.7%) for primary lesion, 50 patients(84.7%) for suboptimal results after PTCA, 6 patients(10.2%) for bail-out procedure, and 2 patients(3.4%) for restenotic lesions. All patients were treated with aspirin and ticlopidinc. The follow-up angiograms were obtained at 7±4 months. The overall in-stent restenosis rate was 27.1%. The coronary angiographic findings were 32 single vessel(54.2%), 19 two vessel(32.2%) and 8 three vessel disease(13.6%). The angiographic morphological characteristics were type A in 33(55.9%), type B in 14(23.7%), type C in 12(20. 3%) cases. Variables of 16 patients with restenosis were compared with those of 43 patients without restenosis. Previously known predictors for in-stent restenosis were multiple stenting, stenting for restenotic lesions, residual stenosis after stenting, stenting for total occlusion lesions, reference diameter, balloon to vessel ratio, acute gain and minimal luminal diameter after procedure, design and characteristics of stents, ostial lesion of aorta, high pressure method for stenting, lesion length, diabetes mellitus, size of artheroma, saphenous vein grafts, ulcerlating lesions and calcified lesions. In this study, Reference diameter before stenting(2.43±0.54mm vs. 2.88±0.65mm, p=0.016) and balloon-to-artery ratio(1.28±0.26 vs. 1.11±0.18, p=0.006) were predictors for in-stent restenosis. 1) The overall in-stent restenosis rate was 27.1%. 2) In the analysis of predictors for in-stent restenosis, there was no significant differences in clinical, angiographic factors between group with restenosis and without restenosis. But, Only reference diameter before stenting and balloon-toartery ratio were predictors of late in-stent restenosis. In conclusion, stenting is effective revascularisation method for selected patients with ischemic heart disease, and to minimize in-stent restenosis rate, stent implanting is achieved in a large vessel on the basis of an artery-to-stnet ration of 1:1, if possible.
