  • 이 연구의 목적은 새로이 제작된 chitosan-poly(L-lactic acid)(PLLA) 다층 다공성 차폐막의 생체적합성 및 골세포활성도 및 골재생능을 평가하는 것이다. 제작된 차폐막을 24 well에 넣고 clonal osteoblast-like cell line(MC3T3-E1)을 접종한 군을 실험군으로, 차폐막을 사용하지 않은 대조군으로 하였다. 배양 1일, 7일 및 14일째에 각 well에서 세포수를 측정하였다. 주사전자현미경을 이용하여 차폐막에 부착된 세포의 형태관찰을 시행하였다. RNA 추출 및 RT-PCR을 실시한 후, agarose gel상에서 전기영동하여 조골세포 표식자인 collagen type I(COL), osteopontin(OP) 및 osteocalcin(OC) mRNA의 발현을 관찰하였다. 제작된 매트릭스의 생체적합성 및 골재생능을 관찰하기 위하여 백서의 두개골에 직경 8mm의 원형 결손부를 형성한 후 차폐막을 이식한 군을 실험군으로, 아무 것도 넣지 않은 군을 대조군으로 하여 4주 경과 후 실험동물을 희생시킨 후 조직학적관찰을 시행하였다. 시간경과에 따른 부착세포수 관찰결과, 배양 14일까지 조골세포의 수가 지속적으로 증가하였고, 주사전자현미경으로 세포의 형태 관찰결과, 배양된 세포들은 중층의 형태로 성장하면서 시간경과에 따라 세포가 응집되는 양상을 나타내었다. 관찰 기간동안 COL, OP, 및 OC mRNA의 발현이 관찰되어 배양 전 기간동안 조골세포의 형질이 잘 유지되고 있음을 알 수 있었다. 백서 두개골 결손부에 이식된 차폐막은 염증반응 없이 주위 조직과 우수한 생체적합성을 나타내었으며, 차폐막을 이식하지 하지 않은 대조군에 비해 높은 신생골 형성을 나타내었다. 이상의 관찰결과로 새로이 제작된 chitosan-PLLA 차폐막은 우수한 생체적합성 및 골재생능을 나타냄을 알 수 있었으며, 향후 이를 골조직 재생 및 치주조직유도재생 분야에 응용될 수 있을 것으로 생각된다.

  • Background : Approximately 50% of patients with low-grade endometrial stromal sarcoma (LGESS) develops recurrent disease, mainly in lung or pelvis. Peritoneal metastasis of LGESS is an extremely rare phenomenon. Optimal treatment for metsatatic LGESS has not been established. Case : A 43-year-old woman had been diagnosed with LGESS with aortocaval lymphadenopathy. Despite of surgical resection, adjuvant radiation, chemotherapy and hormonal therapy, multiple lung and peritoneal metastasis developed after 15 months from initial treatment. Additional chemotherapy was done, but disease progressed. She had treatment with the allergen-removed Rhus verniciflua Stokes (aRVS) from November 2010 to May 2011. About 5 months to progression was observed. Conclusion : We suggests that aRVS could be an alternative treatment option for the metastatic LGESS patients. Further clinical studies on the efficacy of aRVS against metastatic LGESS are needed.

  • Purpose: Schwannoma is a slow-growing, encapsulated benign peripheral nerve tumor that originates from the Schwann cell of the nerve sheath. Schwannoma most frequently involves the major nerve. Schwannoma of the foot is rare. This is a report of our experience with a small, deep-seated, and non-palpable schwannoma occurring in the foot. Methods: A 42-year-old woman presented with the plantar pain of the right foot during 2 years. Physical examination did not identified a palpable mass. She made a clinical diagnosis of plantar fasciitis and was conservatively treated 2 years ago. Since her plantar foot pain was aggravated, she was recently visited again. For the evaluation of her plantar foot pain, sonographic examination of the whole right foot was performed, and it revealed a small hypoechoic hetergenous, deep-seated mass beneath the plantar aponeurosis. At operation, a $0.7{\times}0.6{\times}0.4$ cm sized, ovoid, yellowish grey mass was removed. Results: Histology was confirmed that the mass was a benign schwannoma. There were no postoperative complications. Conclusion: Unsusual case of a schwannoma with the plantar foot pain during 2 years is presented. It should be recognized a small, deep-seated, non-palpable

  • Obstruction of the bile duct owing to the direct extension of a tumor is occasionally found in patients with a hepatic neoplasm, but bile duct tumor thrombus caused by the intrabiliary transplantation of a free-floating tumor is a rare complication of hepatocellular carcinoma A 50-year-old woman was diagnosed with HCC with bile duct tumor thrombi. She received transarterial chemoembolization (TACE) because her liver function was not suitable for surgery at the time of diagnosis. After TACE, infected biloma occurred recurrently. Thus, resection of the HCC, including the bile duct tumor thrombi, was performed. Six months after the surgery, recurred HCC in the distal common bile duct as drop metastasis was noted. The patient was treated with tomotherapy and has been alive for three years as of this writing, without recurrence. The prognosis of HCC with bile duct tumor thrombi is considered dismal, but if appropriate procedures are selected and are actively carried out, long-term survival can occasionally be achieved.

  • Capillary hemangioma of the trachea is an extremely rare benign tumor in adults. We present the case of a 28-year-old woman with hemoptysis owing to a tumor of the proximal trachea. The tumor was removed by rigid bronchoscopy. The resulting specimens showed capillary hemangioma without any signs of malignant transformation. This presentation is the first case in Korea. Although tracheal capillary hemangioma is a rare disease, we should consider it as a possible cause of hemoptysis in the young adult.

  • A 31-year-old woman, who was pregnant with twins, underwent chorionic villus sampling because of increased nuchal translucency in one of the fetuses. Cytogenetic analysis showed a normal karyotype in the fetus with increased nuchal translucency. However, the other fetus, with normal nuchal translucency, had a derivative X chromosome (der(X)). For further analysis, fluorescence in situ hybridization (FISH) and additional molecular studies including fragile X analysis were performed. FISH analysis confirmed that the Y chromosome was the origin of extra segment of the der(X). The X-chromosome breakpoint was determined to be at Xq27 by FMR1 CGG repeat analysis, and the Y-chromosome breakpoint was determined to be at Yq11.23 by the Y chromosome microdeletion study. To predict the fetal outcome, the X-inactivation pattern was examined, and it revealed non-random X inactivation of the der(X). To the best of our knowledge, the identification of an unbalanced Xq;Yq translocation at prenatal diagnosis has never been reported. This study was performed to identify precise breakpoints and the X-inactivation pattern as well as to provide the parents with appropriate genetic counseling.

  • In December 2011, we reported an autochthonous case of Echinococcus multilocularis infection in a 42-yearold woman in Korea. The diagnosis was based on histopathological findings of the surgically resected liver cyst. In the present study, we evaluated the serological and molecular characteristics of this Korean E. multilocularis case. The patient's serum strongly reacted with affinity-purified native Em18 and recombinant Em18 antigens (specific for E. multilocularis) but negative for recombinant antigen B8/1 (reactive for Echinococcus granulosus). In immunoaffinity chromatography, the serum also strongly reacted with E. multilocularis and only weakly positive for E. granulosus. We determined the whole nucleotide sequence of cox1 (1,608 bp) using the paraffin-embedded cystic tissue which was compared with E. multilocularis isolates from China, Japan, Kazakhstan, Austria, France, and Slovakia. The Korean case showed 99.8-99.9% similarity with isolates from Asia (the highest similarity with an isolate from Sichuan, China), whereas the similarity with European isolates ranged from 99.5 to 99.6%.

  • Injury of the musculocutanous nerve can be associated with a proximal humeral fracture or shoulder dislocation, and injury of the brachial plexus. However, injury of this nerve associated with a humeral shaft fracture has rarely been reported. Diagnosis of the musculocutaneous nerve injury is difficult because its sensory loss is ill-defined, and examination of elbow flexion is difficult when it is associated with fractures. We report an unusual case of musculocutaneous nerve injury in a 27 years old woman who had multiple injuries including a humerus shaft fracture, an ipsilateral radius shaft fracture, and an associated radial nerve laceration. Diagnosis of the musculocutaneous nerve injury was delayed because combined fractures of the humerus and radius prevented proper examination of the elbow motion and nerve grafting of the radial nerve delayed early elbow motion exercise. Delayed exploration of the musculocutaneous nerve 6 months after trauma showed complete rupture of the nerve at its entry into the coracobrachialis muscle and the defect was successfully managed by sural nerve graft.

  • The brainstem include midbrain, pons & medulla. In acute stage of brainstem infarction, neurologic symptoms may be progressive. So we must pay special attention to Wallenberg's syndrome. In other words, Wallenberg's syndrome is dorsolateral medullary syndrome. A-54-years-old woman was admitted because of vertigo, ataxia & somatic sensory loss of left face and right half-body. Brain MRI showed high SI in T2W, low SI in T1W lesion left medullary infarction. We diagnosed the case as Shin-heo type Oriental medically and prescribed Gihwangemjakamibang. Diabetes mellitus was found out. So We have controlled diabetes mellitus by Occidental medical therapy. In the end, The symptoms of the patient became better. We know that cooperative(oriental & occidental) medical therapy is better than one medical therapy.Here we present one case of Wallenberg's syndrome who was admitted at Kunpo Wonkwang University Hospital Oriental Neuropsychiatry from 14th March to 6th April. 2001.
