The volumetry by cineangiocardiography is known to have the most diagnostic and prognostic value in theevalutaion of various valvular heart diseases and ischemic heart diseases. Athough many authors favor thearea-length method for the voulmetry of left ventricle, 45degrees RAO projection seems to be more simple,inexpensive and acurate technique, considering the positional relationship of cardiac valves and obliquity of thelong axis of left ventricle within the chest cage. Authors present the anatomical, geometrical and radiologicalbasis for the superiority of 45degrees RAO projection by analyzing 20 normal heart specimen and 115cineangiocardiograms of valvular heart disease, and the results as follows; 1. Blood flow and motility of themitral and aortic valves can be more clearly demonstrated by 45degrees RAO projection than by AP view. 2. The longdiameter of left ventricular silhouette made 45degrees RAO projection reflects 90% or more of real diameter. 3. InRAO 45degrees position, patient's left nipple is optimal and convenient level for the ruler offering accuratemagnification coefficient of left ventricle. 4. Ejection fration after the extrasystole is exaggerated regardlessof the left ventricular function, so it is desirable to exclude the 2 or 3 beats after extrasystole.

PURPOSE: This study was performed to evaluate the features of pulmonary lobes and fissure in Korean and to compare with the previous results. MATERIALS AND METHODS: HRCT scans of 82 healthy Korean adults, performed with scan interval of 1.5/2.0 cm, were reviewed. RESULTS: Located mostly on inner aspect, incidences of incomplete oblique and horizontal fissure were 60% (Rt 48%, Lt 39%) and 51% respectively, lower than 70--80% and 60--75% of western studies. Superolateral oblique fissure, inferior accessory fissure, left horizontal fissure and other accessory fissure were shown in 1%, 13%, 7%, and 8% respectively. Lower lobe upper part faced laterally (Rt 91%, Lt 82%) while lower part faced medially (Rt 61%, Lt 79%). Right middle lobe ws highest posteromedially (49%) and was convex (97%). CONCLUSION: Features of pulmonary lobes and fissure in Korean were similar to the results of previous reports but with lower incidence of variation.

With development of immunochemical methods for anlysis of serum proteins, quantitative determination of serum immunoglobulin levels and purification of them have been made possible in recent years. There are numerous reports about immunoglobulin levels in various diseases. A search of the literature reveals very few reports of quantitative immunoglobulin determinations in allergic dermatoses. The present study was conducted to find quantitative changes of serum immunoglobulins in a few allergic dermatoses. To quantify the IgG, IgA and IgM, one hundred and two sera were analysed form 30 normal control group, 30 contact dermatitis patients, 12 stopic dermatitis patients and 30 urticaria patients by modified Oudin's capillary tube method. The results are as follows. 1.In contact dermatitis the IgG was significantly increased to compare with control group(p<0.01) 2.In atopic dermatitis the IgA was significantly increased to compare with control group(p<0.01) 3.In urticaria the IgG was increased (p<0.05) 4.The IgM has no differences between allergic dermatoses and control group.

Fractures of the femoral head associated with hip dislocation are uncommon injury and all traumatic fracture-dislocation of the hip must be treated as surgical emergencies. But, there was no uniformity of treatment of fracture-dislocations of the hip were treated by operative and conservative methods in Chonbuk National University hospital were observed between March 1983 and January 1987; Operative treatment is included screw fixation method and fixation with bone pegs. And so, the followings were summsrized: 1. The most common cause was dash-board injury and patients sex was msle in majority. 2. Frequency of the type of femoral head fracture was the most in Pipkin type I, the next was type IV. 3. The better result was noted in operative treatment than in conservative method as above good. 4. Bone pegging method was relatively not superior to screw fixation. 5. The following complications were encountered, 1 case of sciatic nerve palsy, 1 case of traumatic arthritis.

PURPOSE: Diffuse panbronchiolitis(DPB) is a chronic inflammatory airway disease of unknown causes mainly affecting the respiratory bronchioles and the more proximal bronchi. Findings on chest radiographs and high-resolution CT(HRCT) are well known and Akira classified HRCT findings of DPB into four types. Purpose of this study is to evaluate the relationship between findings of HRCT and PFT. METHODS AND MATERIALS: We retrospectively analyzed the chest radiographs and HRCT images of eleven patients with DPB and compared CT classification with pulmonary function test. RESULTS: Chest radiographs usually showed small nodular opacities throughout the both middle and lower lungs. The HRCT findings of DPB were centrilobularly distributed small nodular densities, branching linear densities contiguous with small round densities, dilated and thickened peripheral and central airways including bronchioles. More than one CT type by Akira's classification, usually two or three types, were found in nine patients. There was good correlation between CT types and FEV1%(p<0.05), CT types and FEV1/FVC (p<0.05) respectively. CONCLUSION: HRCT seems to be more useful for diagnosis and disease progression of DPB as compared with the chest radiographs or clinical stage such as pulmonary function test.

We present a case of acquired tracheoesophageal fistula (TEF) which was found during induction of general anesthesia for clipping of aneurysm. The patient had been intubated with endotracheal tube for 10 days and then done tracheotomy for 45 days. Thereafter, TEF was confirmed by MRI and treated with fistula repair and tracheal fenestration. Acquired TEF can occur under the condition of prolonged tracheal intubation with high cuff pressure (>30 mmHg) and can also result from intratracheal neoplasm, mediastinitis, and other tracheal or esophageal damages. If unrecognized during anesthetic induction, TEF can cause gastric dilatation and rupture, pulmonary aspiration and respiratory failure. So early diagnosis and proper management is very important whenever TEF is suspected during anesthetic induction.

Double outlet left ventricle (DOLV), even defined as origins of both great vessels from left ventricle,implies varieties of morphology in concern with loop pattern, location of ventricular septal defect, conotruncalanatomy, and presence or adsence of pulmonary stenosis. With the improvement of surgical tenchnique, correctivesurgery of DOLV became possible, and preoperative diagnosis and determination of the accurate anatomicalrelaltionship between great vessels, ventricular septal defect, and ventricles is very important in surgicalimplication. Authors have recently experienced two cases of DOLV. The one is with subpulmonic conus, subpulmonicventricular septal defect, patent ductus arteriosus, and preductal type coarctation of aorta. The other is withbilateral coni and subaortic ventricular septal defect. Loop patterns are [S,D,D] in both cases.

PURPOSE: To evaluate in reperfused myocardial infarction in a cat model, the time-course of signal enhancement as seen on Gadomer-17 enhanced MRI, and to correlate the size of the enhanced area with that of the infarct area as revealed by on histochemical examination. MATERIALS AND METHODS: Five cats which had undergone occlusion of the LAD followed by reperfusion underwent MR imaging. After T2-weighted imaging, Gadomer-17 enhanced T1-weighted images were obtained in four cats during a six-hour period, and in one during a three-hour period. Signal intensities were measured in the enhanced and non-enhanced areas of enhanced T1-weighted images. and using 2,3,5-triphenyl tetrazolium chloride (TTC) histochemical staining, the size of the abnormal signal area on each image was compared with that of the infarct area. RESULT: The enhanced area seen on enhanced T1-weighted images showed rapidly increased signal intensity following the administration of Gadomer-17. Maximum enhancement was detected during a 40 -60 minutes period, with an average enhancement of 168 +/-9.9% of normal myocardium. TTC staining revealed that the size of the high signal area on T2-weighted images and of the enhanced area on enhanced T1-weighted images was greater than that of the infarct area (p<0.05). CONCLUSION: In reperfused myocardial infarction in a cat model, Gadomer-17 enhanced MR imaging delineates both reversibly and irreversibly damaged myocardium, with strong enhancement and a broad temporal window. We may therefore expect that Gadomer-17 is useful for demonstrating myocardial injury.

In hypertensive patients it is very important to detect renal artery stenosis or pheochromocytoma, since both diseases are curable causes of hypertension. However, renal artery stenosis can be induced by pheochromocytoma, when the diagnosis of the two simultaneous disease is very difficult. We experienced two cases of pheochromocytoma presented as renal artery stenosis. Pheochromcytoma was overlooked when renovascular hypertension was diagnosed. Pheochromocytoma was found during surgery in one patient and after angioplasty in the other. In both cases, BP returned to normal after surgical removal of pheochromocytoma without repair of the stenosis. Prevention of ineffective and unnecessary renal artery angioplasty of surgery requires knowledge of this unusal association between pheochromocytoma and renal artery stenosis and a high degree of clinical alertness for pheochromocytoma.
