        Acinar cell carcinoma is a rare tumor that represents 1~2% of al1 pancreatic cancers. Clinical and radiologic findings are inconclusive in this disease Acinar cell carcinoma is characterized by rapid progression and early metastasis, which lead to its poor prognosis. A 41-year-o1d man was admitted to our hospital for abdominal pain. Abdominal computed tomography (CT) and positron emission tomography-computed tomography (PET-CT) showed a splenic mass, which was being invaded by a pancreatic tail mass and which had increased ^(18)F-fluorodeoxyglucose (FDG) uptake Primary radical distal pancreatectomy and splenectomy were performed. Pathologic findings revealed an acinar cell carcinoma of the Pancreas The patient underwent a total gastrectomy three months later because of gastric recurrence Four months later, multiple hepatic metastases were discovered, and the patient underwent a left hepatectomy During treatment with capecitabine, there was no evidence of tumor progression for 14 months. We report a case of metastatic pancreatic acinar cell carcinoma, which did not progress for an extended period while the patient was being treated with capecitabme.

        20년전과 비교한 한국청년의 미소 변화에 관한 연구

        범승균,정지혜,김태영,이경은,동진근 大韓齒科補綴學會 2012 대한치과보철학회지 Vol.50 No.3

        Purpose: Teeth are generally exposed when people smiling. Moreover, the exposed teeth and soft tissue when smiling becomes an important guideline for esthetically prosthetic restoration. This research is to compare and find out differences of Korean young men's smile living in presence and twenty years ago. Materials and methods: Subjects, 100 young men (50 male and 50 female), were required about several aspects; normally developed physical condition, no psychological or genetic disorders, a fine face with no loss of teeth, no experience in orthodontic or prosthetic treatment, relatively normal occlusion, aged between 20 - 29. The photos of the subject at rest position and front face when fully smiled were taken three times. 100 photos (50 male and 50 female) were chosen at random from the 240 university students' smile photos taken by Yoon and his colleagues in 1991. By Hulsey's method of measuring smile, several factors; the change of upper lip curvature, the change of the relation between the upper lip and teeth, parallelism between Mx. incisor and lower lip, contact relation between Mx. incisor and lower lip and teeth displayed in a smile, were measured and analyzed. Meanwhile, ten dentists assessed aesthetic evaluation about men and women's smile for twice and recorded and compared smile score. The -test (P<.05) was used to compare the measured value. The difference of smile score was analyzed by t-test (P<.05). Results: The smile score calculated in 2011 (60.22) was higher than that of 1991 (52.80). Among five measurement categories, the noticeable difference was distinguished from two factors; the change of upper lip curvature and contact relation between Mx. incisor and lower lip. Conclusion: The Korean young men's smile has been considerably improved for twenty years. And it is found that the change of upper lip curvature plays an important role, that is, the smile formed with an ascended labial commissure has been increased significantly. 연구 목적: 일반적으로 치아는 미소 지을 때 가장 많이 노출되며, 미소 시에 나타나는 치아와 연조직과의 관계 등은 심미적인 보철 수복에 있어서 중요한 지침이 된다. 본 연구는 20년 전 한국 청년들의 미소와 현재 한국 청년들의 미소를 비교하여 그 차이를 알아보고자 하였다. 연구 재료 및 방법: 신체적인 발육 상태가 정상적이고 전신적 또는 유전적 질환이 없으며, 안모가 양호하고 치아의 결손이 없으며 교정 및 보철치료를 받은 경험이 없고, 교합상태가 비교적 정상적인 20 - 29세 사이의 청년 100명(남자 50명, 여자 50명)을 대상으로, Cephalometer에 사용되는 두부 고정 장치를 사용하여 피검자의 F-H plane이 지면에 평행하도록 한 후, 35 mm 카메라(400D. Cannon, Japan), 120 mm 렌즈 그리고 삼각대를 사용하여 피검자의 midsagittal plane에 카메라 렌즈의 중심을 맞추고 상악 중절치 절단과 렌즈와의 거리를 930 mm로 하여 안정위 및 full smile 시의 안모 정면 사진을 3회씩 촬영하였다. 1991년 윤 등이 촬영한 대학생 240명 중 무작위로 선택한 100명(남자 50명, 여 자 50명)의 미소사진과 함께 개인용 컴퓨터 및 V-ceph 6.0 프로그램을 이용하고 Hulsey의 미소 계측 방법을 참고로 하여, 상순의 형태, 상순과 치아와의 관계, 하순과 상악 전치 절단연과의 평행 관계, 하순과 상악 전치 절단연과의 접촉 관계, 미소시 나타나는 치아 등을 계측하고 분석하였다. 한편 치과의사 10인이 남,녀 각 2회씩 미소에 대한 미적 평가를 시행하여 미소평점을 기록하고 비교하였다. 결과: 지난 20년간 한국 청년의 미소가 크게 향상되었으며 이러한 변화는 주로 상순의 형태가 영향을 준 것을 알 수 있었다. 즉 입꼬리가 위로 올라가는 형태의 미소가 괄목할 만한 증가를 보인 반면 입 꼬리가 아래로 처지는 형태의 미소는 현저한 감소를 보였다. 결론: 지난 20년간 한국 청년의 미소가 크게 향상되었는데 이러한 변화는 주로 상순의 형태가 영향을 준 것으로 나타났다.

        A 4-month-old female Great Dane dog with abdominal distention and non-productive retching after gulping of food and water yesterday was referred to the Veterinary Medical Teaching Hospital of Chungnam National University. Depression and abdominal distention with tympany were observed on physical examination. Decreased RBC and PCV were observed on CBC. And ALKP, BUN, Glu and P were increased on a serum chemistry. Severe gas filled distention of the stomach and intestines were shown on the abdominal radiographs. Pylorus was displaced craniodorsally toward the left side and gastric body was deviated to the right side on the abdominal radiographs. Deviating cranially of the diaphragm and decreased size of the heart were observed on thoracic radiographs. Therefore this case was diagnosed as gastric dilatation-volvulus.

      • 실험동물에서의 내분비계 교란물질인 DEHP, DBP의 생체내 영향

        정지윤,이성호,박영석,박병권,김병수,김상기,박창식,강경선,이영순 충남대학교 형질전환복제돼지연구센터 2007 논문집 Vol. No.10

        The major protocol features of the rodent uterotrophic assay have been evaluated using a range of reference chemicals. The protocol variables considered include the selection of the test species and route of chemical administration, the age of the test animals, the maintenance diet used, and the specificity of the assay for estrogens. The rodents were ovariectomized under general anesthesia via bilateral flank incisions and randomly assigned to groups of 5 animals. This study investigated the estrogenic effects of phthalates, which are DEHP and DBP, suspected as endocrine disruptors. It is concluded that three daily subcutaneous administration of test chemicals, which are di-ethylhexyl phthalate(DEHP) and di-n-butyl phthalate(DBP), to 9 week-old rodents. The results revealed that DEHP & DBP show similar uterotrophic activity in the rat and the mouse, using subcutaneous administration. DEHP and DBP failed to affect any of these parameters, which are body weight, mammary gland, vaginal and uterus histopathology. but, DBP increased uterus weight to only one rat of 1.0 g/kg group. The results conform the need for rigorous attention to experimental design and criteria for assessing estrogenic activity.

        Background: With reports on the relation between smoking and depression appearing since 1980, it has become clear that depression is one of the psychodynamics of smoking, though there has been little or no progress made in the study of whether or not there is indeed a relation between depression and nicotine dependence. Purpose: The purpose of the study was to investigate the effects of depression on the amount and period of smoking and nicotine dependence among university man student smokers. Method: In periodical examination between 14 and 21, May, 2003, using 170 university male. The CES-D(Center for Epidemiologic Studies Depression) Scale and the FTQ(Fagerstrom Tolerance Qustionnaire) were utilized to measure the level of depression and nicotine dependency. The amount of smoking was calculated based on the number of cigarette used. Result: Results indicated that depression had something to do with amount of smoking. Nicotine dependence also was related to depression but total value was relatively low. finally the period of smoking had nothing to do with depression. Conclusion: The results of this study revealed that the amount of smoking of university man student smokers was very high. Both the amount of smoking and nicotine dependence were affected by levels of depression. Accordingly psychiatric nursing access such as emotional support is needed to manage depression and decrease smoking.

The purpose of this study was to evaluate a 3-Dimensional laser scanner for the space analysis after loss of a primary first molar. Six children with premature loss of a primary first molar were examined using study models taken before and after the extraction. The results were as follows: 1. There was no change in primary molar space after the extraction of a maxillary primary first molar However, 2 out of 3 children experienced primary molar space loss in extraction side of a mandibular primary first molar. 2. Arch width and arch perimeter showed no difference between initial and final model. 3. All primary canines did not show any changes in inclination. Maxillary primary second molars had similar changes in both extraction and control side. However, 2 out of 3 mandibular primary second molars in extraction side showed more lingual tipping compared to control side. Mandibular permanent first molars tipped more lingually in extraction side. 4. In angulation, primary canines showed nothing of significance. Mandibular primary second molars tipped more mesially in extraction side than in control side. Maxillary permanent first molars have increased distal angulation after extraction of primary first molars in both side.

      • 반려동물의 기생충검사 이론 및 실제

        이성호,박영석,박병권,김상기,정지윤,박수진,박창식,김병수 충남대학교 형질전환복제돼지연구센터 2007 논문집 Vol. No.10

        The aim of this article is to improve human health and that of companion animals by improving the diagnosis and control of parasitic diseases. This is achieved by research into parasites of veterinary significance including zoonoses and the use of comparative systems to increase our understanding of some human parasitic diseases. We should promotes learning and teaching through knowledge and operates a diagnostic unit that offers a service to pet owner for indigenous and exotic parasitic diseases of companion animals. We must diagnose and treat them early. Zoonotic parasites are very important because many of animal parasites are zoonoses and give pain and death to human. Parasites are divided Protozoa, Helminthes and Arthropods. There are many protozoa, about 65,000 species. Arthropods are the vector of another diseases, such as virus, bacteria, protozoa and nematodes. Helminthes are composed of Trematoda, Cestoda, Nematoda and Acanthocephala. The target of Veterinary Parasitology is to recognize the characteristics of these parasites and subsequently diagnose, treat and control them. This article is intended to familiarize you with the essential facts and concepts of companion animal parasitology. Emphasis is placed on fecal sample techniques (comparison of fecal examination techniques; frequently found artifacts in fecal smears; direct Smear; zinc sulfate flotation; etc.) We recommend that the study be done to more references on animal parasites.

        운동 행동 분야에서는 어포던스 개념을 적용해서 효율적인 움직임을 이끌어내기도 하고, 인간의 움직임을 로봇에 적용하는 등의 시도가 계속 되고 있다. 따라서 학문별 어포던스 연구가 다양하게 이루어지고 있다. 하지만, 어포던스의 연구 활용도에도 불구하고 아직 체육학 분야에서 어포던스의 이해는 부족한 상황이다. 따라서, 이 연구의 목적은 어포던스 개념의 이해를 돕고 앞으로의 연구 방향을 제시하는데 있다. 연구 목적에 맞게 다음과 같은 내용으로 기술되었다. 첫째, 모호한 개념으로 생각되었던 어포던스 개념에 대해 학자별 발전 내용을 살펴보았다. 둘째, 운동 행동과 관련된 다양한 분야의 어포던스 연구에 대해 논의하였다. 셋째, 인간이 어떻게 어포던스를 지각하는지, 지각 척도에 대해 기술하였다. 넷째, 어포던스 연구를 범주화하고 과제별로 연구의 내용을 기술하였다. 마지막으로 앞으로 스포츠 현장에서의 연구 방향을 제시하였다. The attempt to apply the motion of human to robots has still continued, which derived efficient motion by applying the concept of affordance in the field of motor behavior. Accordingly the study of affordance in each discipline has been accomplished variously. Application of affordance in studies, however, the level of understanding of affordance in athletics is still low. So the purpose of this study is to help people to understand the concept of affordance and suggest the direction of study in the future. The following things have been described suitably to the purpose of study. First, this study reviewed how the concept of affordance considered to be ambiguous has been developed from a vantage point of each scholar. Second, the study of affordance in various fields concerning motion activity was discussed. Third, how human being perceives affordance and the criterion of perception has been described. Fourth, the affordance studies were categorized and the studies were described for each task. Finally the future direction of study in sports site was suggested.
