李定相,李元求 全北大學校 1987 論文集 Vol.29 No.-
A taxonomic investigation was carried out on the mites of the family Tenuipalpidae, plant feeders, which were collected in Cholla-Do Province from October, 1985 to September, 1986. We report the following 3 species belonging to 2 genera: Brevipalpus californicus(Banks, 1904) ; B obovatus Donnadieu, 1875; Tenuipalpus zhizhilashviliae Reck, 1953. Among them, Brevipalpus californicus (Banks, 1904) is recorded from Korea for the first time.

1986년 12월부터 87년 11월까지 채집된 애응애과 응애를 분류학적으로 정리한 바 Brevipalpus속의 B.californicus와 B.ovovatus 2종과 다음의 한국4미기록종을 얻었다: Aegyptobia nothus Pritchard and Baker,Pentomerismus taxi Hailer, P. oregonensis McGregor,Brevipalpus lewisi McGregor. 따라서, 한국산 애응애과 응애는 Tenuipalpus속의 T.zhizhilashiliae(감나무애응애)를 포함하여 4속 7종이 보고되는 셈이다. 또한 P. oregonensis,B.californicus,B.ovovatus 및 B.lewisi에 대하여 polyacrylamide slab gel electrophoresis로 esterase와 alkaline phosphatase pattern을 조사한 바 esterase는 band수와 이동도에서 종과 속간에 뚜렷한 차이를 보였다. Six species of false spider mites were collected and ciassifled in South Korea. Among them, a taxonomic description was carried out on the following four species new to Korea: 1. Aegyptobia nothus Pritchard and Baker, 2. Pentomerismus taxi (Hailer), 3. P. oregonensis McGregor, 4. Brevipalpus lewisi McGregor. And also esterase and alkaline phosphatase patterns obtained by polyacrylamide slab gel electrophoresis were compared on some spades. Esterase rymogram showed difference among species in band number and mobility.

카드뮴이 마우스의 면역반응 및 세포증식능에 미치는 영향
이정상 서강정보대학 1995 論文集 Vol.14 No.-
This study was designed to investigate the effects of cadmium on the antibody production to sheep red blood cells(SRBC) and proliferation of mitogen-stimulated spleen cells in mice. Cadmium treated groups were devided into two groups. One is pretreated subcutaneously with low dose of cadmium chloride(0.5㎎/㎏) for 5 consecutive days from the -7 day relative to the time of primary SRBC immunization (Low dose cadmium treated group). The other is not pretreated with low dose of cadmium chloride (Low dose cadmium non-treated group). Both groups were injected intraperitonealy with high dose of cadmium chloride(5㎎/㎏) 8 hours before primary immunization. Mice were immunized intraperitonealy twice with 0.2m1 of 2% SRBC suspension (10^(8)). The results obtained were as follows, Ⅰ. The number of plaque forming cells to SRBC in control group was higher than both cadmium treated groups, but there was no significancy. Ⅱ. The total antibody titers to SRBC in cadmium treated groups were similar to that of control group, but titers of IgG antibody were elevated significantly(p<0.01). Ⅲ. The proliferation response of spleen lymphocytes to various mitogens was suppressed on proportion to the concentration of cadmium and the degree of cadmium accumulation in liver was increased in the cadmium treated groups. These results suggest that cadmium induced immmune response of mouse was affected by some protective substance such as metallothionein produced intracellulary by various divalent heavy metals.

A case of nonfunctioning paraganglioma of the anterior mediastinum in a 64-year-old woman is presented. The tumor was adherent to the pericardium and parietal pleura but not to the phrenic nerve. Complete excision of the tumor is the treatment of choice, but partial excision may provide long-term survival. A new classification and terminology suggested by Glenner and Grimley is emphasized. This aorticopulmonary paraganglioma is the first case in the Korea.

We have performed 28 single lung transplantation in mongrel dogs transplanting the left lung exclusively from November 1989 to September 1991, in the department of thoracic surgery of Seoul National University Hospital. In the donor dogs, the main pulmonary artery was divided proximal to its bifurcation, and the left atrium was incised freeing the left veins with a generous atrial cuff. We used cold saline in the first 7 transplantations and Euro-Collins or modified Euro-Collins solution in the remaining 17 transplantations as a lung preservatives. The bronchus was divided at two cartilage rings proximal to the upper lobe bronchus take off. In the recipient procedure, we used a Fogarty catheter as a bronchus block. Left atrial anastomosis was performed first using 5-O prolene and the pulmonary artery was anastomosed using 6-O prolene. The bronchus was anastomosed next with 4-O vicryl interruptedly and covered with a greater omentum which had been prepared previously. All dogs received cyclosporin A and azathioprine as immunosuppressants and were divided into two group. In the 10 Group I dogs, they survived within 6 days, mean survival time was 66.8$\pm$53.4 hours. In remainder 14 Group lI dogs, they survived above 6 days, mean survival time was 9. 5$\pm$5.6 days. The cause of death were as follows: 2 cases of sacrifice, 2 cases of respiratory insufficiency during operation, 2 cases of arrhythmia immediate postoperatively, 2 cases of bleeding, others in Group I, and 6 cases of sacrifice, 4 cases of sepsis, 3 cases of bleeding, others in Group lI. Results of bronchoscopic findings were obstruction above 50% in 12 cases of 16 performance cases within 5th day. Early chest radiologic haziness were showed, and total lung perfusion defect was frequently showed in both group within 7th day. Main autopsy findings were left atrial and pulmonary arterial thrombi and bronchial obstruction The major histologic findings of Group I were pleural exudate, hemorrhagic infarct, pulmonary congestion, and interesting histologic findings of Group II were 3 cases of perivascular or peribronchial lymphocyte infiltration, 3 cases of hemorrhage infarct, 2 cases of interstitial pneumonitis. The structual change of bronchioles, suggesting bronchiolitis obliterans was not observed due to improper preparation of proximal pulmonary tissue and short term survival times.
