Excretory urography is a type of contrast study used to verify and localize upper urinary tract disease. It is an inexpensive and easy way to visualize of anatomic and functional status of the kidney and has been used as a primary imaging modality for the evaluation of urinary tract abnormalities. We describe urological signs of 7 dogs who examined with excretory urography and ultrasonography. Six cases were referred to veterinary medical teaching hospital. Chungnam national university (VMTH, CNU) to evaluate renal function after the treatment for renal failure and one case was referred showing hematuria. In case 1, 2 and 4, blood test and urinalysis was normal and the results of excretory urography presented that renal function were normal range. In case 3, the results of urinalysis, ultrasonography, and excretory urography except blood test presented abnormal kidney and hydronephrosis was diagnosed. In case 5 and 6, blood test, urinalysis, ultrasonography and excretory urography indicated renal failure. In case 7, blood test, urinalysis and ultrasonography presented partially abnormal signs, however, the results of excretory urography was normal range.

A 10-year-old spayed female dog with history of persistent nasal discharge and halitosis was presented. In oral examination, there were severe dental calculi and gingivitis. The radiographic imaging showed lesions of left nasal cavity and periodontal membrane. In computed tomographic imaging, there are increased density of left nasal cavity, loss of nasal concha and partial defect of nasal septum. Many inflammatory cells were observed in nasal cytology. The result of culture from nasal smear was negative. All these findings result in rhinitis by dental calculi and gingivitis. The dog got improved after scaling, tooth extraction, and medical treatment.

목적 : 바렛식도는 지속적인 위식도역류 등으로 원위부 식도에 정상적으로 존재하는 편평상피세포 대신에 배상세포를 포함하는 장형 원주세포로 식도 점막이 피복되는 것을 말한다. 그리고 이형성을 거쳐 선암종으로 진행할 수 있기 때문에 이형성 이전 단계인 바렛식도의 발암과정에 대한 연구가 필요하다. 이에 바렛식도와 배상세포를 포함하지 않은 원주세포만 있는 식도를 대조군으로 하여 점액유전자 및 세포증식능에 대해 비교 연구하였다. 대상 및 방법 : 임상 및 내시경적으로 바렛식도가 의심되어 원위부 식도에서 생검한 환자들 중에서 배상세포가 있어 조직학적으로 바렛식도로 증명된 25명의 환자와 배상세포가 없었던 환자들 중에서 무작위로 선택한 30예를 대조군으로 하였다. 생검 당시의 나이와 성별 그리고 MUC1, MUC2, Ki-67에 대한 면역조직화학적 염색을 시행하였다. 결과 : 바렛식도의 평균 나이 및 남자 비율은 각각 65.3±10.1세, 76.0%이였고, 대조군의 평균 나이 및 남자 비율은 각각 53.0±14.8세, 60.0%로 바렛식도의 나이가 대조군식도보다 의의있게 높았다. MUC1은 바렛식도 및 대조군 모두에서 100% 발현되었고, MUC2 발현율은 바렛식도 및 대조군에서 각각 92%, 20%이었다. Ki-67 발현율은 바렛식도 및 대조군에서 각각 80.0%, 70.0%이였고, Ki-67 발현 강도의 평균은 바렛식도 1.20±0.76, 대조군 0.77±0.57로 발현 강도에서 바렛식도가 의의있게 높았다. 결론 : 바렛식도는 원주세포만 있는 식도에서 보다 좀더 지속적인 위식도역류 등의 자극으로 생긴다. 그리고 MUC2는 주로 바렛식도에서 발현되고 세포증식능은 바렛식도에서 좀더 높으며 이는 MUC2 발현과 관련될 수 있다고 생각된다. Background/Aims: Barrett`s esophagus is characterized by the presence of metaplastic columnar epithelium with goblet cells in the distal esophagus. Barrett`s esophagus progresses through low grade dysplasia and high grade dysplasia to adenocarcinoma. We studied the patient age, the mucin gene and the proliferation activity of biopsy-proven Barrett`s esophagus and simple columnar epithelium-lined esophagus. Methods: To evaluate the mucin gene expression and proliferation activity, twenty five cases of Barrett`s esophagus and thirty cases of control esophagus were examined immunohistochemically with using the monoclonal antibodies to MUC1, MUC2 and Ki-67. Results: The Barrett`s esophagus patients were older (mean: 65.3±10.1 years) than the control patients (mean: 53.0±14.8 years). The MUC1 expression was 100% in both Barrett`s esophagus and the control esophagus. An MUC2 expression was observed in 92.0% of the Barrett`s esophagus and 20.0% of the control esophagus. The rate and intensity of the Ki-67 expression was higher in the Barrett`s esophagus (80.0%, 1.20±0.76) than that in the control esophagus (70.0%, 0.77±0.57). Conclusions: Barrett`s esophagus is a metaplastic lesion due to the more long-standing gastroesophageal reflux than that in a simple columnar epithelium-lined esophagus. The cause of increased proliferation activity in Barrett`s esophagus may be related to the MUC2 expression. (Kor J Neurogastroenterol Motil 2007;13:21-25)

Purpose : This study was conducted to develop field triage, transportation, distribution, and prehospital care at a fire disaster by analyzing the victims of the fore that broke out at a bar in Incheon. Method : We analyzed the cases of the victims of a fire in Incheon in Oct. 1999. We determined the primary care hospital, the arrival time, the burn size, the outcome, and the injury type from the medical records, the concerned organ records, and interviews with concerned persons. Result : The total number of victims was 137: 56 prehospital deaths, 1 hospital death, and 80 survivals. The Pearson correlation coefficient between the burn size and the severity was -0.175. There were 121(89.6%) cases of inhalation injury, 59 (43.7%) cases of flame burns, 66 (48.9%) cases of hypoxic brain damage, and 16 (11.9%) cases involving other types of injury. Conclusion : The causes of death of the fire victims were inhalation injury and hypoxic brain damage due to CO poisoning and other toxic inhalants. We propose the use of a simple triage and rapid treatment(START) system and a reassessment the delayed category in fire disasters.

펄프섬유로부터 잉크입자를 효율적으로 제거하여 잉크함량이 적고 백색도가 높은 재생펄프용 탈묵제를 제조하였다 본 연구의 또 다른 목적은 고백색도에 필요한 여러 계면활성제의 적정조건을 찾고 재생펄프의 수율을 높이는 것이다. 본 연구에서 우리는 우수한 탈묵효과를 위해 스테아르산과 여러 유형의 계면활성제를 사용하였다. 그리고 탈묵효율에 미치는 여러 가지 고형 탈묵제의 효과를 알기 위하여 부상탈묵실험을 수행하였다. 그 결과 고백색도와 높은 수율을 얻을 수 있는 새로운 고형 탈묵제의 적절한 조합조성은 스테아르산 75%와 폴리옥시알킬렌알킬아릴에테르 6%를 혼합한 것이었다. 또한 탈묵효과를 폭넓게 적용하기 위해 기포력과 피 안정도, 분산능을 테스트하였다. 새로운 타입의 탈묵제는 폐지 탈묵시 우수한 분산능과 적당한 기포력과 안정성을 나타내었다. A new feinting agent for recycling of waste paper was produced. This agent efficiently removed ink particles from the pulp fiber and the resulting recycled pulp had a high brightness and a low content of residual ink. Efforts were made to find an optimum condition of various surfactants used for high brightness and yield of recycled pulp. In this study, stearic acid was used for various types of general surfactants for deinking. Flotation deinking experiments were conducted in order to examine the effect of various solid-type deinking agents. As a restult, an optimum combination of this new solid-type deinking agent, which resulted in high brightness and yield, was 75 wt% stearic acid mixed with 6wt% polyoxyalkylene alkyl aryl ester. This new type deinking agent had good dispersability, suitable foaming power and foam stability in deinking of waste paper.

In the GIS(Geographic Information System), the construction of a map-database requires vast expense and efforts. The manual and semi-automatic digitizing techniques which are generally used to make a digital map nowadays have limit to productivity, even to experts. Also, the existing methods have problems in maintaining consistent data precision by individual character of operators. In this thesis, we propose a new technique that automatically constructs a map-database by using a domain segmentation algorithm. The proposed technique minimizes the problems of the existing techniques. The reason is that it separates text and pictures domain automatically for coverages and the constructs data for each coverage.

Dictyostelium discoideum의 세포융합

최호형,이기현,서정열 公州大學校 基礎科學硏究所 1996 自然科學硏究 Vol.5 No.-

Dictyostelium discoideum에서 세포 융합율을 높이기 위한 최적조건들을 찾기 위해서 세포 융합율이 빛, 온도, pH 그리고 ?? 의해 어떻게 영향을 받는지를 조사하였다. 빛이 있는 조건 하에서 배양시킨 HN₁과 NC₄를 혼합하였을 때 융합율은 10% 낮아졌다. 빛이 있는 조건하에서 배양된 HN₁과 빛이 없는 조건하에서 배양된 NC₄를 혼합하였을 때 융합율은 위와 같다. 그러나 빛이 없는 조건하에서 배양된 HN₁과 NC₄를 혼합하였을 때 융합율은 60% 높아졌다. 10℃ ~ 25℃ 사이에서 모든 세포들은 융합할수 있지만 시간적인 차이를 보였다. pH 5.5-6.5에서 융합율이 가장 높으며 ?? 농도는 500μM 일때 가장 효과적이고 200μM의 농도는 영향을 미치지 못했다. 그러므로 D. discoideum에서 세포융합을 증진시키는 최적조건들은 : 빛이 없는 조건하에서 HN₁과 NC₄를 배양시키고, pH 5.5, 20℃ 또는 25℃의 온도 그리고 500μM의 ?? 농도이다. In order to find the optimum conditions to raise the rate of cell fusion in Dictyostelium discoideum, we investigated how the rate of cell fusion was affected by light, temperature, pH and ??. When HM₁ and NC₄ cultured in light were mixed, the fusion rate of these was lower by 10%. When HM1 cultured in light and NC4 cultured in dark were mixed, the fusion rate was the same as above. But when HM₁and NC₄both cultured in dark were mixed, the fusion rate was 60% higher. In the range of 10℃∼25℃, all cells can fuse but there was a difference of time. The fusion rate was the highest in pH 5.5∼6.5, and the concentration of ?? was the maximum effective at 500μM and had no effect at 200μM. Therefore, the optimum conditions to elevate the cell fusion rate in D. discoideum were : HM₁and NC₄, that both cultured in dark, pH 5.5, temperature of 20℃ or 25℃ and 500μM ??.
