Pulmonary toxicity of talc containing tremolite asbestos (TCT) has been studied in term sequential in Sprague-Dawely rats. UICC chrysotile(average diameter 0.03${\mu}m$, average length 2.93${\mu}m$) was applied as the positive control. TCT was analyzed for its physicochemical properties by transmission electron microscope equipped with energy dispersive X-ray spectrometer(TEM-EDS). The effects of 2mg TCT(talc average diameter 9.7${\pm}$8.4${\mu}m$; tremolite average diameter 1.6${\pm}$1.6${\mu}m$, average length 10.8${\pm}$7.0${\mu}m$) on pathological changes were evaluated after 1, 8 weeks instilled into rat lungs. 2mg Chrysotile continuously affected lung pathological changes. Inflammation and granuloma response broke out from 1 week after instilled with chrysotile and the pathological examination further showed increased legions of lung after 8 weeks. But TCT did not showed lung pathological changes. The biopersistence of TCT and chrysotile was evaluated by TEM- EDS. Whereas chrysotile continuously have retained to 8 weeks instilled into rat lungs, talc of TCT showed statistically significant decrease of diameter from 1 weeks and statistically significant change in Si atomic % compositions at 8 weeks instilled into rat lungs. Physicochemical properties of tremolite of TCT were not affected until 8 weeks instilled into rat lungs. This study showed that the durability of TCT in the lungs is much weaker than chrysotile.

Bronchoartic Fistula Secondary to Pulmoanry Tuberculosis Bronch-aortic fistula is a exceptionally rare complication of pulmonary tuberculosis. We report herein, a case of 39 years woman who underwent successful repair of aor-tobronchofistula. She was admitted because of massive hemoptysis via emergency room, she had several bouts of massive hemoptysis prior to hospitalization. Thoracic-aortic pseudoaneurysm had detected by chest CT by chance. The eroded, perforated descending aorta was repaired with patch aortoplasty during temporarily clamping, followed by Left lower lobectomy and omentopexy. Pathological examination revealed pulmonary tuberculosis of superiror seg. of lerg lower lobe and aortitis. The patient had uneventful recovery was well at OPD follow-up check.

The bronchogenic cyst is not so rare in incidence, but it is rare for this cyst to cause compression of trachea and main bronchi. A 6-year old female child was evaluated for coughing, fever and left total atelectasis. This patient had a history of frequent upper respiratory symptom like bronchial asthma since 6month after birth. Fiberoptic bronchoscopy revealed external compression at distal trachea and both main bronchi. Computed Tomography revealed well demarcated homogeneous mass compressing distal trachea and main bronchi. The pathological examination showed bronchogenic cyst and this patient had uneventful recovery.

Fecal examination for survey of natural prevalence of Balantidium coli was performed on 1080 healthy bred pigs in Korea, and the positive rate was 56.2%. In order to observe if Balantidium coli might be a secondary invader after certain initiation of the intestinal lesions, the piglet groups preinfected with the protozoa experimentally were treated with Salmonella cholerasuis, Trichuris. cold stress, HCI, and immunosuppressive drug respectively, but no relation was found between them. Also the protozoa were not detected from the intestinal lesions spontaneously formed of 107 pigs which were checked in the slaughter house. According to the above results, Balantidium coli is not directly associated with the formation of any lesions in the pig's large intestine.

We report a rare case of a 38-year-old woman with a bronchial carcinoid tumor arising from an intralobar bronchopulmonary sequestration. The vascular supply to the sequestered left lower lobe originated from the descending thoracic aorta. A left lower lobe lobectomy was performed. The findings of the pathological examination revealed an atypical carcinoid tumor that was immunopositive for chromogranin and synaptophysin. At the 3-year follow-up examination, the patient was healthy.

Primary cyst of the diaphragm is a rather uncommon disease. This is a report of a case of diaphragmatic cyst, located in the tendinous portion of the right diaphragm. The patient had no specific symptoms in the respiratory systems, but suffered from gastrointestinal symptoms [indigestion, epigastralgia, and loss of appetite etc.] for 2 months. Accidentally, on a simple chest x-ray examination, a round homogenous mass density was discovered. Tomography showed a well circumscribed parenchymatous mass. So a coin lesion in the medial segment of the right lower lobe was suspected. A thoracotomy was performed. There were no pathological findings in the lung and pleura. A ping-pong ball sized round mass, which was soft, elastic and fluctuated,was noted in the tendinous portion of the diaphragm. It was enucleated completely without diaphragmatic rupture, and diagnosed as a primary diaphragmatic cyst [fibrous-walled] by the histopathologic examination. Postoperative course was uneventful.

Hyperdontia or supernumerary teeth without associated syndrome is a rare phenomenon, as supernumerary teeth are usually associated with cleft lip and palate or other syndromes such as Gardner's syndrome, cleidocranial dysplasia, and so on. Five patients with supernumerary teeth visited our department. They had no familial history or other pathology, certain treatment protocols was modified due to the presence of supernumerary teeth. Non-syndromic supernumerary teeth, if asymptomatic, need to have periodical radiographic observation. If they showed no variation as they impacted in the jaw, careful examination is necessary because they may develop into pathological status such as dentigerous cysts. The importance of a precise clinical history and radiographic examination for patients with multiple supernumerary teeth should be emphasized.

Pain originating from the sacroiliac joint(SIJ) has been associated with poor performance, yet specific diagnosis of sacroiliac dysfunction(SID) has been difficult to achieve. Clinical presentation of SID appears that pain and poor performance is responsive to local analgesia of periarticular structures with poorly defined pathology, and poor performance with bony pathological changes present as a result of chronic instability. Previous research indicates that physical examination cannot diagnose SIJ pathology. Earlier studies have not reported sensitivities and specificities of composites of provocation tests known to have acceptable inter-examiner reliability. Tests based on mechanics as manual provocation for SIJ pain have formed the basis of tests used to diagnose SIJ dysfunction. In this review summary, the purpose of this study was to describe the sacroiliac tests with a model of examination, diagnosis, and management of SID. Further research is warranted to determine whether SIJ tests is reliable means of evaluating innominate impairments.

A 12-month-old domestic rabbit died suddenly without specific clinical signs. Gross examination revealed irregular yellowish hepatic nodules with pus in the submandibular muscles, lungs, uterus, and small intestines. Histopathological examination of the liver showed granulomatous inflammation with acid-fast-positive bacteria. Mycobacterium bovis SB1040 was identified by polymerase chain reaction and spoligotyping, and Pasteurella multocida was isolated from the multiple lesions. This report demonstrates the pathological features of rare bovine tuberculosis (bTB) in a domestic rabbit, the first case in the Republic of Korea. To ensure public safety, we recommend routine monitoring of rabbits to control the incidence of bTB.
