Many pictures must be taken for the presumption of the stereorelation of the cerebral artery, which obtained with ordinary cerebral angiography. And it is very difficult to understand the stereoimage and required many experiences. But it is able to presume the stereorelationship in only brief eye's training without the aid of the stereoscope using the prism. For the stereoview, we need the paired angiograms obtained only straight and tilting the X-ray tube. In practice, with this stereoview in cerebral angiogram, we could know the directions of the aneurysmal neck and fundus with the stereorelationship of the cerebral artery and indeed helps us greatly in operation field. In addition, we might guess the location and stereorelationships of the feeding artery and draining vein in arteriovenous malformation and other vascular tumors and it was great aid in diagnosis and operation. Now we present the methods of the pictures for the stereoview in cerebral angiogram and the methods for eye's training.

A 77-year old man living in Kyunggi-Do, Korea was surgically treated at Seoul National University Hospital on April 1981, because of acute abdomen. At laparotomy, a 1.77m long adult Taenia saginata was found both in gallbladder and in common bile duct to cause acute gangrenous cholecystitis. The relevant literature were reviewed and possible mechanisms of the disease were discussed.

Histopathological diagnosis of brain stem glioma should be performed for the purpose of the determination of its management and clinical course, but its surgical biopsy has been followed by high mortality and morbidity. We performed the tissue sampling for histological examination with BRW stereotaxic system under local anesthesia successfully.

To evaluate the effect of intertrochanteric femoral derotational osteotomy(IFDO) on the sagittal plane kinematics and kinetics of the hip and pelvis in spastic cerebral palsy, we compared the preoperative and post-operative results of 3 dimensional gait analysis. Intertrochanteric femoral derotational osteotomy alone without psoas procedure was performed in 34 hips of cerebral palsy patients with increased femoral anterversion regardless of preoperative dynamic or static hip flexion contracture. Those who had other concomitant hip procedures were excluded. There were 24 diplegics and 10 hemiplegics. Mean age of the patients at the time of operation was 9.1 years (range, 4.9 to 22). They were divided into three subgroups according to the degree of dynamic hip flexion contracture; 13 patients with normal hip extension in terminal stance (group I), 13 patients with maximum hip extension in terminal stance between 0 and 15 degrees (group II), and 8 patients with maximum hip extension in terminal stance of more than 15 degrees (group III). The gait analysis included clinical assessment, video-taping, 3D-kinematics and kinetics, and dynamic EMG. Linear parameters of gait, kinematic parameters, sagittal plane hip moment parameters, and total hip energy parameters were compared. Postoperatively, cadence and double support time decreased, whereas walking velocity and stride length increased in all groups. Maximum and minimum pelvic tilt were improved in all groups. The range of pelvic tilt improved in all groups except group I. Hip flexion-extension curve shifted into extension in all groups. Marked improvement in maximum hip extension in stance and the range of hip motion were observed in all groups. The sum of extensor moment decreased, whereas that of flexor moment increased significantly in all groups. The conversion timing from extensor to flexor moment significantly improved in group I and II. The decrease of power generations of Hl and the increase of power absorptions of H2 were significant in all groups. However, there were no significant changes in power generation of H3 in all groups. The changes of peak power generation timing of H3 was not consistent among the groups. Femoral derotational osteotomy at the intertrochanteric level brings the lesser trochanter forward resulting in iliopsoas lengthening effect. We found significant improvement of the sagittal plane kinematics and kinetics of the hip and pelvis when IFDO alone was performed without psoas tenotomy. The psoas lengthening procedure may be considered secondarily at the time of hardware removal after full evaluation of the psoas lengthening effect.

Henoch-Schonlein purpura is a common pediatric disease presenting most frequently with skin, gastrointestinal, joint and renal manifestations. But in cases are infrequently only severe gastrointestinal manifestations. It is hard to diagnose promptly and exactly. Clinical manifestations and laboratory findings were observed and analyzed in 20 cases with Henoch-Schonlein purpura which were considered as acute abdomen, hospitalized at Kyung Hee university Hospital during the period from December, 1982 to September, 1992. The following results were obtained; 1) The age distribution of Henoch-Schonlein purpura had a peak incidence between 7 to 9 year old. And male preponderance was observed with male to female ratio of 2.33 to 1. 2) The most prevalent season for the initial presentation of Henoch-Schonlein purpura was in fall: in 10 cases (50%). 3) The frequency of each type of clinical manifestations showed 20 (100%), 20 (100%), 18 (90%), 8(40%) cases for skin, gastrointestinal, joint and renal manifestation respectively in order of frequency. 4) The common previous illness were URI, 40 cases (50%) and allergy, 2 cases (10%). 5) The onset time of skin manifestation from admission were 1 to 4 days (75%0, 5 to 8 days (15%), 9 to 12 days (10%) explolaparotomies were done the last 2 cases. 6) In all cases, X-ray study (100%), abdominal sono (50%), Meckels scan and colon study (5%) respectively were done. 7) Hematologically leukocytosis over 10,000/mm3 was observed in 80% of cases and increase in ESR over 20 mm/hr in 65% of cases. Coagulation studies, immunologic and complement level revealed the result within normal range in most of the cases. 8) Among 8 cases with renal involvement, all cases had both hematuria and proteinuria. 9) Most cases were recovered within 4 weeks but in 4 cases, renal biopsies were done because of relapse. The results were Meadow classification grade I (1 case), II (1 case), IVa (2 cases). After renal biopsy, steroid pulse therapy was started.

The gross tissue specimens are a valuable aid to the teaching of pathology and anatomy. However, traditional methods for storage and handling of them are discouragingly difficult and, recently, minimal surgical resections as well as preoperative interventions make it more difficult to have instructive gross specimens. Plastination is a process of tissue preservation by impregnation with silicone polymers or epoxy resins. The process in our study involves dehydration by cryosubstitution in aceton, defatting, forced impregnation of silicon polymer in a vacuum, curing and finishing. We submitted 40 surgically resected specimens to plastination. The resulting specimens are odorless, relatively dry, durable, life-like, non-hazardous, maintenance-free, and do not deteriorate with time. Plastinated specimens are a useful adjunct to the teaching of pathology, particularly suited for use in small groups, and appropriate method of tissue preservation. They are much preferred to wet preparation and conventional pots by both students and teachers owing to their accessibility, superior illustrative powers, and comparative ease of interpretation.
