The 150 kDa protein of cyst fluid (CF) of Taenia solium metacestodes was purified by ammonium sulfate fractionation and Superose 6 HR gel filtration chromatography. The purified protein consisted of three subunits (15, 10 and 7 kDa proteins), which were analyzed with the use of a 7.5-15％ gradient sodium dodecyl sulfate polyacrylamide gel electrophoresis (SOS-PAGE). Immunofluorescence study was carried out by using immunize specific polyclonal antibody. Positive reactions were noticed at bladder walls, calcareous corpuscles, granules of cyst fluid and some host tissue surrounding the bladder wall of the metacestodes. These results suggest that the 150 kDa protein was secreted into host tissues, inducing immune responses in the host, and it may play important roles in the cellular physiology of the parasites.

The dermoid cyst is the one of common space occupying orbital lesion. This lesion is regarded as a non-invasive tumor, but infrequently causes destruction of adjacent bony structure and displacement of adjacent tissue. We experienced a characteristic ovoid orbital dermoid cyst that occupied in the frontal sinus and causes displacement of the eyeball with well-defined lining. This 55-year-old male presented a mass in left orbit, which rapidly increased in size for past 12 months, and patient could not open left eyelid. We removed this tumor totally then reconstructed the orbital roof and frontal sinus with an iliac bone graft and polyethylene sheet(Medpor Newnan, USA). This patient was followed up for 12 months and patient obtained satisfactory result without any complication suck as recurrence or infection.

Cyst is pathologic disease develops in hard tissue as well as soft tissue, which is lined by epithelium filled with liquid, semi-liquid, or air. Origins and symptoms of the cyst are various according to region, and symptoms are malocclusion, diversion of root, tooth mobility, periapical swelling, discoloration and lesion expansion, because the odontogenic cysts begin in the numerous rests of odontogenic epithelium. But almost cysts produce no symptoms unless secondary infection occurs. Treatment of small cysts may include extraction, endodontic therapy, and apical surgery. Treatment of a large cysts usually involves surgical removal (enucleation), Marsupialization(a method of decompression) or combination of two before mentioned. Bone graft is done for helping of bone defect healing at the same time of enucleation This clinical research from January 2000 to December 2005, analyzed by the age, sex, classification, size, region, treatment method, whether or not of bone graft of cyst in the jaw in Daegu Catholic University Hospital.

낭종이란 액체 또는 반유동액 물질을 함유하는 병적인 상피로 둘러싸인 공동을 말하며 악골에 발생하는 치성 낭종은 치배, 치관의 잔존 법랑상피, Malassez의 상피잔사 및 구강상피의 기저세포층에서 기원한 낭종을 말한다. 이러한 낭종 발생시 적출술, 조대술, 감압술 및 외과적 절제술의 방법으로 치료가능하며 이는 낭종의 특성, 크기, 주변조직과의 관계, 환자의 나이와 성별 및 협조도와 전암 여부 등을 고려하여 선택하게 된다. 본 증례는 미성숙 영구치가 매복되어 치성 낭종이 발생한 환아에서 감압술을 이용하여 낭종이 제거되고 골조직으로 치유되었으며 매복되었던 영구치가 맹출하였고 낭종이 재발되지 않아 양호한 결과를 얻어 이에 보고하는 바이다.

치근낭은 가장 흔한 치성기원 낭으로 치수감염, 치수실활, 외상으로 인한 이차감염 또는 치아 우식에 의해 발생한다. 보통치근낭은 무증상이나 이차 감염이 발생할 경우 통증, 부종, 발적 등을 유발할 수 있으며, 크기가 커질수록 치근낭은 인접한 신경을 압박하여 안면비대칭 또는 마비증세를 일으킬 수 있다. 치료는 보존적 신경치료 또는 외과적 처치를 요하며, 낭의 크기가 크거나 인접 조직의 침범을 야기할 가능성이 있는 경우에는 낭적출술을 시행해야 한다. 대부분의 증례에서 완벽한 치료가 가능하고 재발율이 낮다. 본 증례의 환아들은 하악전치부 낭을 주소로 내원하여 임상검사에서 일부 하악전치가 괴사되었음을 발견하였으므로 근관치료를 시행한 후 전신마취하에 치근단절제술 및 치근낭 적출술을 시행하였다. 이후 컴퓨터단층촬영을 시행하여 이환부의 골생성 및 재발여부를 관찰하였으며 성공적인 결과를 보였기에 이를 보고하는 바이다.

Fibrous dysplasia is a benign fi bro-osseous lesion wherein normal bone is replaced with an excessive proliferation of cellular fibrous connective tissue intermixed with irregular bony trabeculae. Fibro-osseous lesions like fibrous dysplasia are often associated with non-epithelial cysts, such as simple bone cyst. The etiologic and pathogenic relationships between fi brous dysplasia and simple bone cyst have not been conclusively established. Nonetheless, the mechanism of cyst formation in fibro-osseous lesion associated with simple bone cyst can be said to differ from that of the typical simple bone cyst of the jaws. This article reports a case of bilateral lesions including fi brous dysplasia and simple bone cyst on each site and reviews the pathogenesis of cyst formation in the fibro-osseous lesion.

Purpose: Ganglion cysts of peripheral nerve are uncommon. Ganglion cysts located within the nerve and extraneural ganglia that cause symptomatic nerve compression have been reported. We report an unusual case of epineural ganglion cyst confined to the epineurium of the sural nerve at the foot. Methods: A 45-year-old woman was referred because of a mass on the foot. She had six months' history of pain and numbness in the right small toe. During the examination of the lesion, multinodular cystic mass was identified arising from the epineurium of the sural nerve. The nerve fascicles were compressed by the cyst, but the cyst wall clearly did not invade the fascicle. With the aid of surgical microscope, the epineural cyst was completely excised along with epineural tissue to which it was attached, and the sural nerve was decompressed. There was no relationship between the cyst and either the joint capsule or tendon sheath. Since the cyst was on the periphery of the nerve it was possible to remove the cyst intact without damaging the underlying fascicles. Results: The postoperative course was uneventful. Pathologic examination showed a ganglion cyst with a degenerated collagen fibers and contained a yellowish, jelly-like mucinous substance. No neural elements were identified within the cystic wall. Her sensory impairment improved progressively. At the 15 months follow-up, she was asymptomatic with no neurological deficits. Conclusion: Rarely, ganglion cysts can involve peripheral nerves, leading to varing degrees of neurological deficits. Intraneural intrafascicular ganglion may be difficult to separate from the neural elements without nerve injury. Epineural ganglion, subcategorized as intraneural extrafascicular ganglion, can be removed without damage to the underlying nerve.

목적: 신체 검사 및 초음파 검사를 통한 연부조직 종괴의 진단과 수술 후 조직검사를 통한 결과를 상호 비교, 분석하고 초음파 검사의 임상적 유용성에 대하여 고찰하였다. 대상 및 방법: 본원에서 연부조직 종괴에 대해 수술 전 초음파 검사를 시행하였고, 조직학적 생검을 통한 병리학적 검사로 확진을 받은 총 83명의 환자를 대상으로 한 후향적 검사를 시행하였다. 병력 청취와 신체 검사를 바탕으로 한 임상적 진단과 초음파 검사를 이용한 진단의 정확도를 조직학적 생검을 통한 확진을 바탕으로 상호 비교하였다. 결과: 초음파를 이용한 수술 전 진단의 정확도는 86.7%로 신체 검사만을 통한 진단에 비해 높은 정확도를 보였다. 초음파 검사의 경우 표피성 봉입낭종(epidermal inclusion cyst)인 경우 71.4%, 결절종은 85.7%, 지방종은 88.6%의 정확도를 각각 나타내었다. 반면 신체 검사와 병력 청취를 통하여 임상적 진단이 가능했던 경우는 총 54례로, 이 중 33례에서 병리적 진단과 일치하여 61.1%의 민감도를 보였다. 이 경우 종양별 진단 정확도는 결절종이 56.0%, 지방종이 67.9%로 나타났다. 결론: 초음파는 수술 전 연부조직 종괴의 진단에 있어 매우 유용한 진단 수단의 하나로 사료된다.

Renal cyst was detected in a mongrel dog aged 3 months old. The most prominent clinical abnormalities were vomiting, loss of appetite, depression, abdominal swelling and lethargy. Gross appearances included ascites and bilaterally irregular capsular surfaces of the kidneys. Characteristic microscopical findings were various sized cysts formation, shrunken glomeruli with hypercellularity, connective tissue porliferation in the interstitum, tubular dilatation and sligth leukocytic infiltration. The cause. of the renal disorder in a mongrel dog could not be determined.

The case of the extensive dentigerous cyst treated by intubation technique is reported. 1) An incision is made, and the sterile polyethylene tube is inserted into the prepared opening so that it gently contacts the base of the lesion in 11 year old man. 2) The purpose to maintain vitality of adjacent tooth was achieved by means of intubation in lesion. 3) After 9 months, the extensive periapical lesion was completely replaced with new bone tissue.
