The cytotoxic effects of S hyodysenteriae strain B 204 on the mucosal surface were studied in surgically prepared ligated colonic loops in two male convenitonal mixed-breed pigs. In each one of four loops was inoculated with either sterile trypticase soy broth(TSB) of Serpulina, filtrate of Serpulina TSB culture. washed Serpulina cells or whole culture of Serpulina. Mucosal tissues were examined by transmission and scanning electron microscopy 24 and 48 hours after inoculation(p.i.). The filtrate did not induce any significant effect on the mucosal surface. The washed cells produced early lesions similar to those caused by the whole culture. These observations suggest that cytotoxins of the culture do not play a significant role in invasion of the epithelium in this experimental infection. The possible role of toxins associated with the organism at the site of interaction with the epithelial cells was not elucidated.

Low grade fibromyxoid sarcoma (LGFM) is a rare, deep soft-tissue malignant tumor. Although its histologic features are benign, the clinical course is malignant. The usual tumor locations are the lower extremity and chest wall. LGFM originating from the visceral pleura is extremely rare. We report here on a 37 year old man with a LGFM of the visceral pleura. Thirty three months after surgery, the patient is alive without any sign of local recurrence or distant metastasis.

Multiple coronary aneurysms are rare in adults. The cause may be atherosclerosis, congenital malformations, post-traumatic or post-syphilitic vascular lesions, connective tissue diseases like Marfan and Ehler-Danlos syndromes or Kawasaki disease, all of which cause weakening of the media. Surgical intervention is indicated to prevent rupture, embolization or compression symptoms. The successful management of multiple coronary artery. aneurysms, associated with previous rupture and arrhythmia, originating from proximal potions of ramus intermedius and left circumflex artery are reported.

The definition of fascial spaces are latent spaces between fascial planes. If infections which spread from dental origin to soft tissue are mild, they are restricted by fascial planes. But, when infections are severe, fascial spaces are often used as a natural pathway which spread to the deep cervical region. If they are not treated at early stage, they may result in the fatal complications as followings; airway obstruction, septicemia, cerebral abscess, and thrombophlebitis etc. The early treatment of fascial space abscess is very important for young children. These case reports present the successful result of fascial space abscess treatment through intracanal drainage without surgical excision. It is proven that the treatment through intracanal drainage has some benefits to the surgical excision, which are as follows: 1) It is economic to the patients or their parents avoiding admission. 2) The treatment procedure is more simple. 3) Childrens can avoid the fearful environment.

Two dogs presented to the Dueckso Animal Hospital with a history of intermittent lameness of the left forelimb. On physical examination, a visible antebrachial deformity that resulted in gross external rotation of approximately $90^{\circ}$ was observed in two dogs. Medial-lateral radiographic views revealed distal ulnar subluxation, cranial bowing of the radius, radial and ulnar shortening, and external rotation of the paw. A distal ulnar ostectomy and distal radial closing wedge osteotomy were performed in two dogs. A proximal ulnar osteotomy was performed, adjacent to the elbow joint in case 1. Then, the osteotomized site was supported with an intramedullary pin. A T-plate and cortical screws were applied to the proximal and distal radial segments after derotating the distal segment internally. Postoperative radiographic view verified the correction of the angular deformity in two dogs. The follow-up was completed by physical examination 6 and 10 months after surgery respectively. There was no evidence of lameness of the left forelimb in two dogs. Gross observation of the limb revealed an apparent appropriate correction of the rotational and angular deformity in two dogs.

Loss of mandibular continuity due to neoplasm, trauma, or infection results in major esthetic and biologic compromise. The use of costochondral grafts for reconstruction of temporomandibular joint, described first by Gillies in 1920, has been accepted as a suitable method for replacing the mandibular condyle, especially in growing children. Autogenous iliac bone graft has been a satisfactory source of mandibular reconstruction since Sykoffs report in 1900. Autogenous bone grafts from the posterior aspects of the ilium provide large amount of PMCB with acceptable donor site morbidity. In timing of reconstruction, initial disease, age, medical history, growth and development, esthetic and psychologic factors should be considered. We present a case of osteosarcoma in the mandible that was treated by a hemimandibulectomy and the defect was reconstructed 20 months later with composite method of costochondral and posterior iliac bone graft.

Solitary fibrous tumor is an uncommon sybnesitgekuak mesenchymal neoplasm that arises primarily from the pleura. Extrapleural solitary fibrous tumors are rare. Solitary Fibrous tumors are often asymptomatic and discovered incidentally but may become symptomatic when vital structures are involved or they grow large. In general, solitary fibrous tumor is diagnosed on the basis of radiologic findings and its histologic features, with immunohistochemistry serving to support the diagnosis. Most solitary fibrous tumors pursue a benign course, and the single most important predictor of clinical outcome is the ability to excise the entire lesion. We experienced a case of intrapulmonary solitary tumor arising from the right lower lobe which was treated with wedge resection. We report this case of the patient.

Overall 25,095 cases of general thoracic surgery were analysed, which were performed by 48 institutes in Korea during recent 6 years[242 hospital-years]. The proportions of tumorous disease and infectious disease to be operated were 6,864 cases[27.4%] and 6,775 cases [27.0%], The most common organ involved for operation was lung-bronchus 16,542 cases [69.5%], and remainders were pleura 2,500 [10.0%], esophagus 2,433[9.7%], mediastinum 1,902[7.6%], chest wall 1,297 [5.2%], and diaphragm 421 [1.7%] in order. Among 6,864 cases of tumorous diseases, the most common causes for operation were lung-bronchus tumor 3132 cases [45.6%] and most of them were lung cancer 2,731 cases [88.7%]. In the 2,019 cases of primary lung cancer with known cell type, squamous cell carcinoma 1,296 cases [64.2%] and adenocarcinoma 460 cases [22.8%] were the most. The common types in the 1,207 cases of mediastinal tumor with known cell type were neurogenic tumor 348 cases [28.8%], thymoma 311 [25.8%], and teratoma 252[20.9%]. The annual cases of operation for tumorous disease including malignant tumor were increased steadily. Operation for infectious lung diseases [including bronchiectasis and tuberculosis] were about twice common than infectious pleural disease [i.e. empyema], and operations for tuberculous disease occupied about half cases of infectious lung disease. In 11,456 cases of other disease entities, excluding tumorous and infectious disease, there were bullous lung disease 9,074 cases[79.2%], benign esophageal disease 484[4.2%], myasthenia gravis 356[3.1%], chest wall deformity 483[4.2%], and diaphragmatic lesion 421[3. 7%] in order. We propose that above results for inquiry can be used as the basic data of general thoracic surgery in Korea.

Pulmonary artery aneurysms are extremely rare conditions usually associated with congenital cardiac defects that cause increased pulmonary blood flow and pulmonary hypertension. The prognosis of pulmonary artery aneurysms is fatal due to the potential for rupture of the aneurysm and the underlying severe pulmonary hypertension. A 40-year old woman was admitted to our hospital with headache following traffic accident. On admission a continuous murmur was heard over the 2nd to 3rd intercostal space along left sternal border and a calcified cystic mass at left hilar portion was incidentally discoverd on chest reontgenogram. Cardiac catherization was diagnostic of a left to right shunt at main pulmoanry artery level and pulmonary hypertension. Pulmonary angiogram demonstrated a large aneurysm of main pulmonary artery extending into proximal left pulmonary artery. The pulmonary artery aneurysm associated with patent ductus arteriosus was diagnosed definitively and the patient was underwent resection of pulmonary artery aneurysm, closure of PDA and Dacron prosthetic graft replacement under cardiopulmonary bypass. The postoperative course was uneventful and the patient was discharged without any problem.

일반적으로 개심술에는 많은 양의 실현이 따르게 마련이고 그 결과로 많은 수혈을 하게 되는데, 응혈 이상증, 과민반응, 급성호흡곤란증 등의 수혈부작용과 간염 및 후천성면역결핍증 등의 질병 감염의 위험성, 그리고 종교적인 이유 등으로 최근들어 동종수혈을 줄이고자 하는 노력이 계속되고 있다. 개심술시 동종수혈에 따른 부작용을 피하기 위해, 동종수혈 없이 자가수혈만으로도 성인개심술이 가능한지 연구하였다. 서울대학교 의과대학 흉부외과학 교실에서는 1996년 1월부터 12월까지 1년 간 자가수혈만으로 개심술을 시행한 실험군 126명과 동종수혈을 시행한 대조군 45명을 대상으로 양군을 비교하였다. 양군 간에 환자의 성별, 대동맥 질환을 제외한 기타 질환, 대동맥수술과정을 제외한 단순 및 복잡수술과정, 평균 대동맥 겸자시간, 수술전 및 수술후 1일째와 7일째 혈색소수치 및 적혈구용적, 수술 전후의 protein 수치와 수술후 albumin 수치, 자가수혈량과 혈장증량제 사용량 등에서는 유의한 차이가 없었으나, 연령, 대동맥질환 및 대동맥수술과정, 평균체외순환시간, 수술 후 회수된 피의 양, 수술직후의 혈색소수치와 적혈구용적, 수술 전 albumin 수치, 그리고 3일간 흉관으로 배액된 양에 있어 차이가 있었다. 본 연구를 통해 동종수혈 없이 자가수혈만으로도 큰 차이없이 여러 종류의 성인 개심술을 성공적으로 할 수 있음을 보고한다.
