Objective : The aims of this study were to observe how body weight and gastric morphology were changed and whether gastric emptying was impaired in rats with partial pyloric obstruction. and to evaluate whether electroacupuncture was able to restore delayed gastric emptying. Methods : Partial pyloric obstruction was induced by wrapping a nonabsorbable rubber ring around the 1st portion of the duodenum for 2 weeks. Body gain and morphologic changes of stomach were investigated and compared with normal intact rats. Gastric emptying was measured by numbering expelled glass of beads in rats. Rats were divided into 4 groups(non-acupuncture, manual acupuncture. 3Hz-electroacupuncture. 60Hz-electroacupuncture). Stimulus intensity in two electroacupuncture groups was 1.2 times of pain threshold. Results : Partial pyloric obstruction produced a significant loss of body weight and induced a significant increase of gastric surface area. The 60Hz electroacupuncture-stimulated group significantly restored the delayed gastric emptying compared to the other groups of rats with partial pyloric obstruction. Conclusion : 60Hz electroacupuncture stimulation on Zusanli(ST36) showed significant restoration of delayed gastric emptying in rats with partial pyloric obstruction.

Retrophayngeal hematomas frequently develop in patients who had cervical vertebra fracture. The hematoma develops in the space between buccopharyngeal fascia and prevertebral fascia. But it rarely causes severe airway obstruction. We recently treated a patient who had dyspnea and dysphagia due to a retropharyngeal hematoma without any significant trauma history. First, tracheostomy was performed to maintain the airway. Then, incision and drainage was done under suspension laryngoscope. This case shows the fact that a retropharyngeal hematoma can result in severe airway obstruction even after a minor trauma.

In the presence of clinical evidence and chest roentgenogram suggestive of bronchogenic carcinoma, reliance is almost wholly placed on Papanicolaou staining of the sputum, bronchoscopy, and biopsy of peripheral lesion, together referred to as the "diagnostic triad". However, bronchography remains relatively non-utilized. Our experience with 56 bronchograms in which the modality of bronchial obstruction, distance to obstruction and reduction rate of caliber in leading bronchus were used in an attempt to explain underlying chest pathology and operability of bronchogenic carcinoma, indicated as follows: 1. The bronchographic findings in bronchogenic cancer consist of malignant bronchial obstruction in which the modality of obstruction is classified as abrupt type, conical type and compressed type in incidence of 50.0%, 23.2% and 26.8%, respectively. 2. Abrupt type of bronchial obstruction is more common in hilar type and particularly in squamous cell and undifferentiated cell type of bronchogenic cancer. In this type of obstruction the inoperability revealed in 57.8% and resectability in 17.8%. 3. Conical type of obstruction was a sign of most malignancy, in which 61.5% was undifferentiated cell type and 38.4% was squamous cell type. All this type of obstruction was inoperable even feasibility was presumed in simple roentgenograms. 4. Compressed type of obstruction was more common in peripheral type of bronchogenic cancer and showed 50.0% of resectability. 5. The distance from carina to bronchial obstuction revealed average 3.8cm in undifferentiated type, 5.76cm in squamous cell type and 7.60am in adeno cell type of carcinoma. 6. The reduction rate of caliber in leading bronchus to obstruction (mm per unit cm lenghth of leading bronchus) revealed average 2.15mm/cm in undifferentiated type 1.90mm/cm in squamous cell type and 1.13mm/cm in adeno cell type of carcnoma. 7. The reduction rate of caliber in leading bronchus showed 2.14mm/cm in inoperable cases and 1.42mm/cm in resectable cases. 8. The modality of bronchial obstruction and estimation of the reduction rate of caliber seemed to be a most reliable key-point to decide feasibility of resection.

목적: 조영 증강 삼차원 자기공명혈관촬영술에서 관찰되는 내경정맥 폐쇄의 원인을 조영 증강 전산화단층촬영술을 이용하여 분석하고자 한다. 대상과 방법: 2005년부터 2008년까지 두경부 조영증강 자기공명혈관조영술과 조영증강 전산화단층촬영술을 함께 시행한 30명의 환자를 대상으로 하였다. 조영증강 자기공명혈관조영술에서 내경정맥의 폐쇄가 있는 경우 폐쇄군으로 하였고 내경정맥의 폐쇄가 없는 경우 대조군으로 구분하였다. 다음의 지표를 조영증강 전산화단층촬영술에서 분석하였다 : 1) 내정정맥의 직경; 2) 경상돌기와제일경추의 외측돌기와의 거리; 3) 제일경추의 외측돌기의 최대넓이 이후 각각의 지표를 폐쇄군과 대조군에서 비교하였다. 결과: 폐쇄군에서 내경정맥의 직경 그리고 정상돌기와 제일경추의 외측돌기와의 거리는 각각 $1.6{\pm}1.0\;mm$ 그리고 $4.1{\pm}2.1\;mm$로 평가되었으며 이는 대조군과 비교하여 유의하게 작게 분석되었다 (p < 0.01). 폐쇄군에서 제일경추의 외측돌기의 최대 넓이는 $103.4{\pm}25.3\;mm^2$로 평가되었으며 이는 대조군과 비교하여 유의하게 넓은 것으로 나타났다 (p < 0.05). 결론: 조영증강 자기공명혈관촬영술에서 보이던 대경정맥 폐쇄의 원인은 제일경추의 비대칭적인 큰 넓이에 의한 것 일수 있다.

CGD 환자에서는 면역 체계의 결함으로 인한 반복적인 감염과 육아종 형성이 특징적이다. CGD 환자에서 육아종의 형성에 의한 식도 폐쇄는 매우 드문 합병증 중 하나로 CGD 환자의 육아종 형성에 의한 식도 폐쇄의 치료에 대해서는 불현성 감염이 동반될 가능성이 있어 스테로이드 치료와 항생제 치료에 대한 논란이 있어왔다. 저자들은 항생제 치료에 반응하지 않는 육아종 형성에 의한 식도 폐쇄 증상을 보인 8세 만성육아종질환 환자를 보고하는 바이다. 환자는 스테로이드 치료 이후에 임상적 증상과 영상 검사 상의 급격한 호전을 보였으나 스테로이드 치료를 중단한 지 한 달 뒤 환자의 식도 폐쇄 증상은 재발하였고, 이는 스테로이드를 재 투약 후 호전되었다. 스테로이드 중단 이후 한 차례 다시 재발하였으나, 항생제 치료 후 호전되었고 이후 추가적 재발 없이 경과 관찰 중이다.

소아에 비해 성인에서 발생한 신우요관이행 부폐색의 두드러진 임상적 특징은 소아에 비해 양측성인 경우가 현저히 적었으며, 진단이 지연되었음에도 불구하고 수술 성공률은 소아에서와 비슷하였다. 향후 소아 및 성인의 신우요관이행부폐색 환자에 대한 광범위한 임상 통계가 이루어진다면 이 질환의 정확한 자연사를 알 수 있으며, 또한 성인에서 발생한 이 질환이 태아나 소아 때부터의 질환인지, 아니면 성인이 되어 발생한 질환인지 확인할 수 있을 것이다.

X-ray를 기반으로 하는 장 폐색 진단 방법은 검사자의 주관적인 요소가 포함되기 때문에 객관적 진단에 영향을 미칠 수 있다. 따라서 본 논문에서는 허프 변환과 PCM 클러스터링 기법을 적용하여 장폐색 영역을 추출하는 방법을 제안한다. 제안된 방법은 X-ray 장폐색 영상에서 ROI 영역을 추출한 후, 허프 변환 기법을 이용하여 ROI 영역에서 직선을 검출하고, 검출된 직선을 이용하여 공기 액체층의 형태학적 특징을 이용하여 대장 폐색을 추출한다. 그리고 추출된 ROI 영역을 PCM 클러스터링을 적용하여 ROI 영역을 양자화 한다. 양자화된 ROI 영역 중에서 대장 폐색의 특징이 포함된 클러스터의 그룹을 선정하고, 선정된 클러스터의 그룹에서 객체를 탐색하여 소장 장폐색 영역을 추출한다. 장폐색 환자의 X-ray 영상 30개를 대상으로 PCM 클러스터링을 적용한 결과, PCM의 초기 클러스터의 수를 4개로 설정한 경우가 장폐색 검출 성능이 우수하였고 TPR은 81.47%로 나타났다.

Experimental obstruction of urethra was induced for 66 hours on 5 male dogs to determine the diagnostic value of ECG and blood chemical values. The results obtained in the examination were summarized as follows ; 1. Changes of ECG, blood chemical values and clinical sings were observed from 30 hours after urethral obstruction. 2. In ECG, the peaked and amplitude of T wave were increased remarkably. p wave were decreased, and intervals of PR(Q) and QRS complex were prolonged after urethral obstruction. 3. The levels of BUN, potassium, creatinine in serum after urethral obstruction were increased remarkably and correlation between these levels and the increase of amplitude in T wave were recognized to be significant.

An 8-year-old spayed female Maltese (2.5 kg of body weight) presented with the primary complaint of loud heart murmur and exercise intolerance. Diagnostic imaging revealed severe pulmonic stenosis (peak velocity 5.2 m/s) with right ventricular hypertrophy. The dog revisited after 2 years, at which time, diagnostic imaging revealed severe biventricular hypertrophy, dynamic left ventricular outflow tract obstruction, left atrial dilation and pulmonary hypertension with worsened pre-existing pulmonic stenosis. Postmortem investigation revealed hypertrophic cardiomyopathy and regional myocardial infarction. The case was diagnosed as hypertrophic cardiomyopathy secondary to severe right and left ventricular outflow tract obstruction.

Seven patients [six women and one man] with obstruction of hepatic portion of inferior vena cava was operated on, from May, 1969 to January, 1985. Of seven patients, six were undergone corrective operation for IVC obstruction and another one was not operated because of far advanced liver cirrhosis. The occlusions were found at or close to the level of diaphragm and they were membranous or diffuse with or without thrombi. Most of their symptoms were referable to either inferior vena caval or hepatic venous obstruction and onset of the symptoms was usually gradual, beginning between the age of their thirties and forties. Most of the patients showed marked elevation of peripheral venous pressure of lower extremity [29-40 cm H2O] preoperatively, which decreased significantly after corrective operation [17-30 cm H2O]. Venous catheterization for pressure study and venography were essential for confirming the diagnosis. Of six cases, in which corrective operations were done, Transatrial membranotomy with or without IVC dilatation were performed in five cases [case 1, 2, 3, 5, 6], using cardiopulmonary bypass and in another one case, bypass operation between IVC, distal to obstruction, and RA was done using Dacron tube graft under the thoracoabdominal incision. All survived and their conditions were improved.
