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.

The purpose of this study is the approach to I.I.C.P. centered on the meaning of consciousness disorder and the pathological aspect of Kwul(lose consciousness ; faint, fall, into a coma). The meaning of consciouseness disorder and apoplexy is evidently involved the definition of Kwul. 1. It is found that the etymological interpreation on Kwul which the energy rises back to go through blocked space and the meaning interpretation of regarding Kwul as apoplexy with medical viewpoint, are related with consciousness disorder and motor distrubance in IICP in the aspect of the rise fo Kwul and the abnormal rising of vital energy and blood, In addition, the overall of meaning of Kwul is showed in table <1-1> by reference to doctors of many generations. 2. The pathology of Kwul includes abnormal rising, sthenia-syndrome in the upper part and asthenia in the lower, the origin of Kwul, the lower, looking like Yin by too sthenic Yang and looking like Yang by too sthenic Yin. The headache, vomiting, papilledema, paralsis of nervi craniales, coma, blood pressure rising, tachycardia by I.I.C.P can be regarded as a conception of trouble of vitalenergy, sthenia-syndrome of Kwul. The pulse pressure, brachycardia, bradypnea can be regarded as the conception of looking like Yin by too sthenic Yang. 3. In the emergency of Kwul, the abnormal ternimal reversion of the Kwulyin channel, Kuyang channel, and three Yins are realted with the phenomenon in I.I.C.P. It is considered that the reverse movement of materials, I,I.C.P. can be closely observed by giving meaning on the meridian of Kwul in Somunkwulron. And the content of phrases of Naelyung which includes consciousness disorder refered in the chapter of Kwul, is compared with I.I.C.P. 4, The followings should be considered ; examination of optic symptom and abnormal posture in cerebral herniation ; understanding and working out counterplans of factors and symptoms of consciousness disorder by the observation of vital sign, check of general stages, neurologic inverstigation, clinical diagnosis, and subsidiary diagnosis ; application of morphological change of opinion ; addtion of the conception of demonstration centered on Yunkyoungm, Samyinkwulruk, asthenia and thenia of healthy energy in oriental medicine. 5. The similarity of Kwul and I.I.C.P. can be found from etilolgy and pathotenic factor. The similarity is clearly found by investigation of etiology, pathotenic factor, symptoms and thrapy of Kwul, disease symptom and other symptoms.

본 연구는 치열궁 길이 부조화(Arch length discrepancy : 이하 ALD)의 원인요소간의 상대적 중요성과 혼합치열기에서의 예측가능성을 알아보고자 시행되었다. Angle씨 I급 대구치관계이며 근기능 이상이나 골격형태의 이상이 없다고 판단되는 142명의 진단모형을 이용하여 성별과 ALD의 양에 따라 여섯군으로 나누어 각 치아의 크기와 치열궁 각 부위의 크기를 계측하였다. SPSS 통계처리 프로그램을 이용하여 각군의 평균, 표준편차를 구하고 Student t-test, 상관관계 분석, 요인분석, 다중회귀분석을 실시하였으며 혼합치열기에서 얻을 수 있는 자료들을 이용한 ALD의 예측가능성을 평가하여 다음과 같은 결과를 얻었다. 1. 성별에 따른 차이는 정상군에서는 거의 보이지 않았으며 spacing군은 대부분의 계측치에서, crowding군은 몇가지 치열궁의 크기에 관한 계측치에서 유의한 차이를 보였다. 2. 남자 crowding군과 여자 spacing군은 해당 정상군에 비해 주로 치아크기에 관한 계측치에서 유의한 차이를 보였다. 3. 남자 spacing군과 여자 crowding군은 해당 정상군에 비해 치열궁의 크기에 관한 계측치에서 유의한 차이를 보였다. 4. 상관관계분석과 요인분석결과에서는 주로 치열궁의 크기에 관한 계측치들이 ALD와 큰 연관성을 나타내었다. 5. 혼합치열기에서 얻을 수 있는 정보인 중절치, 측절치, 제1대구치의 폭경과 제1대구치간 폭경, 치열궁 장경을 이용한 ALD의 다중회귀분석은 최소 63%에서 최대 80%의 예측도(R square)를 보였다. The purpose of this study was to estimate relative importance among the causative factors of arch length discrepancy(ALD) and possibility of prediction of the ALD in the mixed dentition. The sample consisted of the casts of the 142 young adults who had no abnormal muscle function, no skeletal abnormalities and Class I molar relationship. We classified the sample by gender and the extent of ALD, and measured mesiodistal diameters of each tooth and the dimensions of the dental arch. The computerized statistical analyses was carried out with SPSS win program. The results were as follows ; 1. Most of the variables of spacing group and some variables of dental arch dimension of crowding group were significantly different between genders. But in normal group, there were few differences. 2. In male crowding and female spacing group, mainly measurements of tooth dimension were significantly different from those of normal group. 3. In male spacing and female crowding group, measurements of dental arch dimension were significantly different from those of normal group. 4. The measurements of dimension of dental arch were highly correlated with ALD in correlation analysis and factor analysis. 5. Prediction equations for adult`s ALDs by means of what can be measured in the mixed dentition(mesiodistal dimensions of incisors and first molar, intermolar width and arch length) showed R square from 63% to 80%.
