  • A 32-year-old female was admitted for evaluation of known mass on right suprahilar area. Chest PA showed $4{\times}3cm$ round and homogenous mass on suprahilar area. No abnormal findings were found in PFT, cytology, bacterial study, and fine needle aspiration biopsy(FNAB). On chest computed tomography, solitary mass was on right suprahilar area and no evidence of intrapulmonary metastasis or lymphnode metastasis was seen. Right upper lobectomy of lung was performed and Castleman's disease of hyaline vascular type was diagnosed based on the histologic findings of multiple and large lymphoid follicles with prominent vascular proliferation and hyalization in the central portion.

  • Lymphoid hamartomas are a rare benign disease which can be easily treated by complete surgical excision. They developed most often in the thorax, and can be discovered usually on routine chest X-ray.p But some of them can also be found because of pressure symptoms or the presence of a palpable mass if outside the thorax. We experienced a case of the hyaline-vascular type of lymphoid hamartoma in the left hilum of a 29 year-old Korean male in March, 1979. He was well except intermittent cough and left chest discomfort of a year duration and was treated by resection of the left upper lobe including nodular tumor masses. The histological characteristics were an aggregation of lymphoid follicles composed of concentrically arranged mature lymphocytes with centrally placed thick walled arterioles showing endothelial proliferation and some of them were hyalinized. Between the follicles, there was extensive capillary proliferation and infiltration of numerous lymphocytes, scanty plasma cells and eosinophils.

  • 한국산 부추속 16종 5변종의 총 21분류군에 대하여 성적특성, 지하부의 구조 및 형태, 지상부의 생자양상, 엽신과 화경의 모양 및 내부구조, 화피, 화사 및 암술의 형태 등의 외부형태형질을 재검토하였다. 그 결과를 토대로 각 분류형질의 특수화 및 진화경향성을 고찰하였고, 분류군들간의 유연관계와 계통을 추론하였다. 진화경향성이 있는 형질은 근경과 인경을 포함한 지하부, 잎, 화경, 화서, 화사 및 자방의 모양 등이었다. 근경의 형태는 비후형에서 미세형으로 발달하였고, 인경의 외피는 얇은 막질에서 그물상 섬유질로 진화한 것으로 여겨졌다. 막질의 초상엽은 달래에서만 관찰된 파생형질이였으며, 엽신은 단면이 둥글고 유관속이 환상으로 배열하는 것에서 각진 형태를 거쳐 단면이 납작하고 넓어지면서 유관속이 1열로 배열하는 것으로 분화한 것으로 추정되었다. 화경의 개화 전 생장은 직립하는 것이, 그리고 화사는 치편이 발달하지 않은 것이 원시적이며 자방은 실 당 2개의 배주를 가지는 것에서 1개씩 가지는 것으로 진화한 것으로 여겨졌다. 한편 성적특성, 지하부의 구조, 막질의 초상엽의 존재유무 및 잎의 내부구조는 아속 수준에서, 지하경 및 인경의 형태, 잎의 모양, 화경 및 소화경의 모양은 아속 내 절 수준에서 분류체계를 결정해 주는 좋은 식별형질이었다. 화피와 화사의 모양 및 배열은 자방 및 주두의 모양과 함께 종을 구분해 주는 좋은 식별형질이었다.

  • The neck of the talus is its most vulnerable and fragile segment, because of narrow diameter, devoid of hyaline padding and honeycombed internally by vascular channels etc. Talar neck fractures comprise 50% of all major to the talus. The majority occurs as a result of high-energy injuries, such as motor vehicle accidents or fall from a height. Anatomically, talar surface is covered mainly with articular cartilage and blood supply to the talus is very poor. So, complications, such as non-union, avascular necrosis and post traumatic arthritis, are frequent. The authors reviewed fourteen cases of talar neck fractures treated in our clinics from Jan. 1992 to Mar. 1997, and average follow-up period was over 15 months. The results obtained were as follows; 1. Patients' average age was 31.2 years. 2. The most common cause was traffic accident(9/14, 64%), and hyperdorsiflexion injury of the ankle was common mechanism of the fractures. 3. According to the modified Hawkins classification, type I was four cases, type II was nine cases, type III was one case and type IV was no case. 4. Hawkins sign of subcortical radiolucency was found in 64% (9/14) of the fractures. 5. Avascular necrosis was occurred in 21% (3/14) of the fractures(in two cases of type II fractures, and in one of type III). 6. According to the Hawkins criteria, four cases in type I, five in type II were an excellent result. Two cases, one in type II and one in type III were good result, and two in type II were fair. One in type II was poor result.

  • Castleman's disease is an uncommon lymphoproliferative disorder. The disorder can be classified based on histological subtype, such as hyaline vascular type, plasma cell type, and mixed type, and can also be clinically divided into either unicentric or multicentric type. Its exact pathophysiology is not clearly identified. The unicentric type is able to be treated by surgical resection. However, there is no standard treatment modlity for the multicentric type. Treatment of multicentric type includes anti-cancer chemotherapy and radiation therapy. Recently, authors have experienced a rare case of unicentric type of Castleman's disease accompanying a mucoepidermoid carcinoma of parotid gland and report a case which is discussed with references.

  • Objectives: Castleman's disease(CD) is a lymphoproliferative disorder of unknown etiology. To elucidate the clinicopathologic characteristics of CD, we retrospectively reviewed our experience. Methods: Fifteen patients with CD of the neck and mediastinum were identified. Patients were divided into two groups: group I had an unicentric CD and group II had multicentric CD. The histology of CD was divided into 3 subtypes: hyaline-vascular(HV), plasma cell(PC), and mixed. Results: The study included 12 cases of group I, 3 cases of group II in the clinical aspect and 10 cases with HV, 3 cases with PC, 2 cases with mixed type in the histologic aspect. Of group I patients who underwent complete surgical excision, all are currently free of disease. The clinical course of group II patients was variable. Of two patients with multicentric plasma cell CD who were treated, one remain free from disease and the other had a local recurrence in the neck. One patient with multicentric mixed CD died of disease after 30 months of presentation. Conclusion: Surgical resection is recommend for patients with the unicentric CD, regardless of histologic subtype. Patients with multicentric disease do not benefit from surgical resection and should be candidates for multimodality therapy.

  • 급성호흡곤란증후군 (acute respiratory distress syndrome)을 포함한 급성폐손상의 기전을 산화성스트레스와 연관하여 알아보기 위하여 본 연구를 시행하였다. N-nitroso-N-methylurethane (NNNMU)은 실험동물에 있어서 사람에서 보이는 ARDS와 유사한 병리학적인 소견을 보이므로 ARDS의 모델로 사용된다. 본 연구에서는 흰쥐에서 NNNMU로 급성폐손상을 유도한 뒤 이를 Lung weight/Body weight ratio, 폐포세척액(BAL)내의 단백함량을 측정하여 확인하고, 동시에 호중구의 침윤에 의한 산소기형성, 이에 따른 산화성스트레스를 확인하기 위하여 BAL 내의 호중구수의 산정 및 폐장의 MPO 활성도를 측정하였다. 동시에 광학현미경, 전자현미경 및 세포화학적 전자현미경법을 이용하여 호중구에 의한 급성폐손상, 호중구의 침윤 및 미세구조의 변화 및 산소기의 생성을 확인하였다. 대조군에 비하여 NNNMU를 투여한 흰쥐에서는 BAL 내의 단백질이 증가하고 BAL 내의 호중구의 증가, 폐장의 MPO 활성도의 증가로 호중구의 침윤이 증가함을 관찰하였다. 광학현미경상 호중구의 침윤, 폐포내 호중구의 유입 및 vascular cuffing 등이 관찰되었다. 전자현미경 소견상 제2형 폐포세포는 산화성 스트레스의 전형적 소견을 보이고 조직의 손상은 호중구에 의한 손상으로 생각되었으며 세포화학적 전자현미경법으로 산소기의 생성이 증가됨을 확인하였다. 이러한 결과들을 종합할 때 NNNMU에 의한 급성폐손상은 호중구의 산소기 생성에 의한 산화성스트레스에 의한 것으로 생각되었다.
