The purpose of this study was to evaluate the effect of a subsequent infection of porcine reproductive and respiratory syndrome(PRRS) virus to pigs with A. pleuropneumonia in pigs. Twenty three 7-weeks-old commercial pigs were infected with PRRS virus and/or A. pleuropneumoniae serotype 5 intratracheally. Feed conversion, clincal signs, gross and histopathological lesions and immunohistochemical findings were examined. 1. Feed conversion ratio in dual-infected pigs with PRRS virus and A. pleuropneumoniae were higher than that of single- infected pigs with PRRS virus or A. pleuropneumoniae. 2. Dual-infected pigs with PRRS virus followed by A. pleuropneumoniae showed more severe clinical signs and gross, histopathological and immunohistochemical pulmonary lesions. The results indicated that dual infections with PRRS virus and A. pleuropneumoniae caused more severe respiratory lesions and growth retardation in pigs than single infection with PRRS virus or A. pleuropneumoniae.

Radiograph and serum activities were investigated in six dogs with experimental portal vein branch ligation. Operative mesenteric portography showed the incomplete portal vein circulation due to ligation of portal vein branch. Several serum enzyme activities were measured after portal vein branch ligation. Albumin and total protein were decreased following the time. Others were increased. In microscopic findings, hepatocellular necrosis and haemorrhage were identified in midzone and centrilobular zone. And reverse lobulation pattern was found in dogs with portal vein branch ligation.

A 50 year old man with acute aortic dissection DeBakey type I, involving right coronary artery and aortic valve, underwent replacement of the ascending aorta and aorto-right coronary bypass grafting. The operative findings showed a large transverse intimal tear was at about 4cm above the aortic valve. The dissection extended out into the proximal right coronary artery. And we found that the right coronary artery originated from the left sinus of Valsalva, run transversally in the aortic wall, with partial rupture. Postoperatively he had no ischemic cardiac symptoms and neurologic complications. He was discharged on postoperative 9th day with good result.

This 51 years old male patient was admitted to the department of thoracic and cardiovascular surgery via OPD because of anterior chest pain. 7days before admission, He got the chest trauma after traffic accidents,the lateral chest roentgenogram showed complete transverse sternal fracture. He also complained of mild dyspnea. We also noticed that he had depressed anterior chest wall. It looks like funnel chest. The operative findings revealed dislocated & callus formations at the both 4th and 5th costochondral junction and transverse fracture of sternal body between 4th and 5th costochondral junction, the upper end of sternal fracture was situated below the lower end of sternal fracture. The two ends of sternal fracture were situated at the same level and reapproximated the two ends by two-interrupted wire sutures. The patient is well on the road to recovery after the operation.

Autologous blood transfusion is a common method of reducing the need for homologous blood transfusion during cardiac operations. Between June 1991 and May 1992, 12 cases [Group I] were experienced autologous blood transfusion using Cell Saver undergoing double valve replacement or redo-valve replacement. Control group [N=12, Group II] was selected to above similar operation during same period. The Cell Saver system [Haemonetics Corp.] was employed for autologous blood transfusion. The blood shed in the operative field before and after cardiopulmonary bypass and remained cardiotomy reservior was aspirated by means of a locally heparinized collecting system. After centrifused salvaged blood, the resulting red cell concentrate reinfused subsequently. The patient receiving autologous blood transfusion required significantly less homologous blood transfusion than their control group. [Group I; 3519 $\pm$ 869, Group II; 4622 $\pm$ 856, Respectively; P=0.005] There were no clinical infections in the autotransfusion group. And there was no apparent intergroup difference of the clinical findings, hematologio datas and coagulation parameters. We conclude the autotransfusion using Cell Saver is effective for reducing of the hom-ologlous blood transfusion in cardiac surgery.

More than one cerebral aneurysm on the same artery is uncommon. Furthermore multiple aneurysms on the anterior communicating artery(ACoA) is very rare. We surgically experienced one case of two separate aneurysms on the ACoA ; one developed at the junction of the ACoA with the right second branch of anterior cerebral artery, and the other on inferior wall of the ACoA itself. The former, confirmed as ruptured on operation, projected superiorly and the latter directed inferiorly toward the prechiasmatic cistern. Radiographic and operative findings are presented with review of literature.

The gallbladder is a pear-shaped, thin walled sac located on the inferior surface of the liver between the right and quadrate lobe, in a recess called fossa vesicae felleae. It is 7.5cm-12.5 cm in length, 3.5 cm in the largest width, and has a volume of about 45 ml with a remarkable capacity for expansion. There are many kinds of diagnostic methods to evaluate diseases of biliary tract including gallbladder-Plain abdomen, Oral cholecystography. Intravenous cholangiography, Percutaneous transhepatic cholangiography(PTC), Endoscopic retrograde cholangiography(ERCP), Operative or T-tube cholangiography, Ultrasonography, Radioisotope study, Computed tomography, and Angiography. Especially, ultrasonography is the most effective and noninvasive study in these days. Plain abdomen, oral cholecystography, intravenous cholangiography, and ultrasonography have been performed in our clinic. Methods and findings of above mentioned study are discussed with consideration of references.

Subannular aortic aneurysm is a word-wide rare disease entity occurring predominantly in young black men. In Korea, there has been no report. We report one patient, 46 years old man, who had been operated urgently because of acute aortic insufficiency and aortic valvular vegetation after antibiotics treatment of Subacute bacterial endocarditis for 6wks. At the operative field, We found the bulging aneurysmal mass between the aorta and superior vena cava above the right pulmonary artery, which has subannular communicating opening into the left ventricular cavity, beneath the anterior commissure of the bicuspid aortic valve. Pathologic findings are consistent with "portion of vascular wall with features of aneurysm.* The patients survived aortic valve replacement and patch closure of subannular aneurysm, with no symptoms at one-year postoperative follow-up.w-up.

Morgagni, in 1760, 1st. described the findings of substernal herniation of abdominal contents into the thoracic cavity, based upon 25 postmortem dissections. Herniation through the foramen of Morgagni is the rarest occurrence of the congenital diaphragmatic hernias and is usually a few symptoms. With the increasing use of routine chest roentgenogram & the need to exclude the possibility of a mediastinal neoplasm, most such cases are brought to the attention of a surgeon. We had experienced 2 cases of Morgagni hernia, which one caused a simple mechanical intestinal obstruction & diagnosed as acute appendicitis with perforation & another one was diagnosed as mediastinal lipoma on routine chest X-ray film at arrival due to traffic accident. We had performed left paramedian abdominal incision as misdiagnosis of acute appendicitis with perforation and repair of the defect and returned transverse colon & stomach into abdominal cavity in one patient. And in another patient, we preferred to approach through right thoracotomy incision and then left upper paramedian abdominal incision and returned the omentum into the abdominal cavity. The post-operative courses were in uneventful and we report these cases and review and discuss the literatures.

The selection of an appropriate surgical technique for repair of aneurysm of the ascending aortia with aortic insufficiency is unsettled. The etiology of the disease process has been the best indicator for the type of repair. Placement of a supracoronary graft[seperate graft and valve] is a compromise if the coronary ostia are displaced cephalad by the aneurysm, where as insertion of a valved conduit is difficult and unnecessary if the coronary ostia are normally placed. A 53 year old female patient underwent primary repaiar of proximal dissected layer and aortic valve replacement with 24mm carbomedics, The operative findings consisted of a supravalvular intimal tear, cicumferential dissection, dilated aortic annulus and normal position of coronary ostia. She is good physical activity now llmonths posoperatively.
