The study was undertaken to evaluate the radiological and microscopic findings of radiation pneumonitis. All 50 rats, which were used for the experiment, received a single dose of 2,000 rads of radiation on right lung using 60 Co teletherapy. Chest teleroentgenograms were checked weekly for 13 weeks and microscopic examination of irradiated lung were performed monthly after irradiation. The resuls obtained are summerized as follows. 1. Inroentgenologic examination, radiation pneumonitis began to appear 4 weeks after irradiation and progressed withtime intervals and began to resolve after 11 weeks. 2. Chest roentgenologic findings were pneumonic consolidation,atelectasis, and pleural effusion of irradiated right lung with compensatory hyper-inflation of left lung. 3. Inthe microscopic examination, pneumonitis appeared 2 weeks after irradiation and progressed with time intervals andbegan to resolve after 8 weeks. 4. The microscopic findings were fibrin deposit in alveoli and increased septalcellularity, vascular thickening, edema and congestion. After septal fibrosis and hyperplasia of bronchialmucosa, suggseting early regenerative change of radiation fibrosis, were noted 12 weeks after irradiation.

Billiary cystadenoma and cystadenocarcinoma are rare neoplasms of the biliary ductal system. The authorspresent 2 cases of biliary cystadenoma and 3 cases of cystadenocarcinoma. The typical sonographic apearance ofthese tumors is a large intrahepatic gloular or ovoid thickwalled cystic mass which often containes multipleseptations with papillary growth and solid portion. Low-level internal echoes may be seen within the cystic mass.The characteristic CT findings of these tumors are multiloculated cystic mass, thick sepatations with papillaryprojection sand solid portion within the cystic mass. Angiographical characteristics of these tumors arehypovascular mass with frequent abnormal clusters of tumor vessels within the walls on arterial phase andaccumulation of contrast material along the wall or internal septation on delayed film.

Nine cases of gastrointestinal leiomyosarcoma were studied by ultrasound. Abdominal sonogram disclosed a largelobulated iso or hypoechoic mass containing a few or multiple central sonolucent cavitations in seven cases. Twocases arising from mesentery and abdominal wall were hypoechoic mass without central sonolucent area. Thesecentral sonolucent areas were condirmed to be necrotic or hemorrhagic cavities in the solid mass pathologically.Although not pathognomonic, a large lobulated exophytic gastrointestinal mass with central sonolucent areastrongly suggests the diagnosis of leiomyosarcoma.

OBJECTIVE: To verify the effect of Matrigel, a ECM complex from Engelbreth-Holm-Swarm(EHS) mouse sarcoma on the preimplantation development and apoptosis of mouse fertilized eggs. METHOD: Late Pronucleus stage eggs were cultured through the blastocyst stage in the presence of Matrigel (0.5%, v/v). Characteristics of apoptosis and cell number assessed by Hoecst staining and TUNEL labeling at the blastocyst stage, respectively. RESULTS: Morphological development, number of cells per embryo was significantly increased but rate and number of TUNEL positive nuclei of the embryo were decreased in the presence of Matrigel. CONCLUSION: This result suggested that at low concentration of Matrigel improves both viability and morphological development in the preimplantation mouse embryos.

Embolization of a carotid cavernous fistula(CCF) by means of a detachable balloon is a well-established method for treating CCFs while preserving a patent parent internal carotid artery(ICA). However, failure to embolize the CCF may occur on a few occasions. Herein we describe a stent-assisted Guglielmi detachable coil embolization that completely occludes the fistulous opening rather than fills the cavernous sinus. By applying this technique, we successfully treated a CCF, without compromise of the parent ICA in patients who has failed with balloon technique previously.

The purpose of this study is to review epidemiological and clinical characteristics of diverticular disease of the colan in Korea and to discuss the difference of the findings from those in other countries. Reviewing all thebarium enema films taken at the Seoul National University Hospital retrospectively for the last 8 years. that is, from January 1, 1980 to December 31, 1987, we observed the annual and overall incidence of the disease, the number and location of the diverticula, and the presenting symptoms of the cases. The results are summarized as follows: 1) Out of the patients examined, 237 cases had one or more diverticula in the colon, the overall incidence being 1.32%, 2) The annual incidence increased progressively for the last 8 years, from 0.25% in 1980 to 2.53% in 1987. 3) The mean age of the patients at the time of diagnosis was 51 years. The male to female ratio was 2.5. 4) The diverticula were located on the right side in 81.0% of the cases, on the left side in 10.6%, and on both sides in 8.4%. 5) In 82 cases (34.6%) single diverticulum was found, whereas 34 cases (14.3%) had more than 10 diverticula. 6) The most frequent symptoms for taking barium enema were abdominal discomfort and pain (34. 2%) and changes in bowel habits (33.8%}, whereas 45 casea (19.0%) had the examination just for a routine health check. In conclusiion, the diverticular disease of the colon is still uncommon in Korea as compared with in western countries, and the right colon type is far more freqtaent than the left colon type. However in recent years the incidence increases quite rapidly and the left colon type is getting more common.

Since the introduction of surgical microscope in microvesael surgery by Jacobson and Suarez in 1960, many surgeons have succeeded replantation, transplantation of composite segment of tissues so called free fiap-free bone graft and toe to hand transfer. McCraw & Furlow reported successfully transfered dorsal foot flap using dorsalis pedis artery in 1975 and Cobett transfered great toe to band for reconstruction of the amputated thunb. The authors experienced six cases of microsurgery using dorsalis pedis artery durig the recent two years in the department of Orthopaedic surgery of Soon Chun Hyang College and results in this paper. 1. Four cases out of six were dorsalis pedis free flap, one case was second toe to thumb and tbe other one was reconstruction of an amputated thumb in one stage using iliac bone graft and dorsalis pedis flap. 2. One case out of four cases of dorsalis pedis free flap was performed for reconstruction of contracted first web and the other cases were performed for foot. 3. Five cases out of six were successfully transfeed, one case which was toe to thumb was failed. The cause. of fail was probably due to post-operative hematoma. 4. Composite tissue using dorsalis pedis artery is one of the good donor site for composite tissue transfer for not only skin defect and scar contracture of the hand and foot but also reconstruction of the amputated fingers because it has several advantages; an acceptable thickness, a constant arterial supply, venous drainage through the saphenous system, and constant innervation through the terminal branches of the superficial and deep peroneal nerve.

To differentiate amebic and pyogenic liver abscesses, sonography(US) and CT findings of 21 amebic and 22 pyogenic liver abscesses were reviewed retrospectively. US was performed in all cases and CT in 15 cases of each group. Eleven cases of amebic abscesses had well defined margin which was observed in 10 cases of pyogenic abscessed. Amebic abscesses showed hyperechoic wall in 7 cases and calcification in 4 cases. Ten cases of pyogenic abscesses had mearby intrahepatic duct dilatation which was observed in 2 cases of amebic abscesses. Pneumobilia was seen in 6 cases of pyogenic abscesses. US findings of clear margin and hyperechoic wall, and CT findings of intrahepatic duct dilatation, pneumobilia, and calcification were helpful in differentation of amebic pyogenic liver abscesses.
