We have experienced 5 cases of unusual well differentiated thyroid carcinoma with insular component during the past 5 years. 4 cases were presented with cervical masses but I case (patient 2.) was initiallty with lung and brain metastasis. The tumors from 4 cases showed invasive growths but that of 1 cases(patient 1.) showed intrathyroidal. Total thyroidectomy and cervical lymphnode dissection(CCND or RND) was performed in 4 cases but only RND was performed in spite of mediastinal metastasis of the tumor in patient 5 under the patient's choice. During the follow-up period, we also performed radical nephrectomy and metastatectomy for the kidney and iliac bone metastasis respectively, in patint 2. Microcsopically, the tumors showed the insular growth patterns, focally(less than 50%) in 3 cases and predominantly(more than 75%) in 2 cases. And the insular componentas were combined with papillary carcinoma in 2 cases and follicular carcinoma in 3 cases. Cervical lymphnode metastases were confirmed in 4 cases. Patient 2 died of disease with metastases to lung, brain, bone and kidney, 52 months after initial therapy. Patient 1, 3 and 4 are alive and have no recurrence and distant metastasis. Patient 5 is also alive with the mediastinal metastasis. In our experience, the well differentiated thyroid carcinomas with insular component showed characteristic histologic features, aggressive behavior in initial presentation and unfavorable prognosis regardless of the percentage of the insular component.

Objective : To confirm the efficacy of functional hemispherectomy and peri-insular hemispherotomy on treatment of intractable epilepsy. Materials & Methods : From April 1997 to February 1999, we performed 1 functional hemispherectomy and 6 peri-insular hemispherotomy in 7 consecutive patients. These procedures result in completely disconnected hemisphere while maintaining the disconnected portion of the hemisphere intact within the surgical cavity. The indications were hemimegalencephaly in 2 cases, infarction with encephalomalacia in 2, Sturge-Weber syndrome in 1, hemiconvulsion hemiplegia epilepsy syndrome in 1, cortical dysplasia with leptomeningeal cyst in 1. Mean follow-up is 15.8 months(range 8-28 months). Results : Among 7 patients, 1 patient died immediately after peri-insular hemispherotomy. Five patients became seizure free with reduced doses of medications. One patient developed rare disabling seizure with medication. In 6 patients, there were improvements in the function of the hemiparetic limbs in the postoperative phase. A 3-year-old boy with infarction and encephalomalacia died few hours after surgery due to postoperative hypothermia. Two patients required shunt after surgery. Two patients developed postoperative brain swelling but were successfully managed with conservative care. Conclusion : In conclusion, functional hemispherectomy and peri-insular hemispherotomy may provide substantial seizure control in selected cases of young hemiplegic patients with intractable epilepsy.

Insular carcinoma(poorly differentiated thyroid cancer) is defined as a aggressive, follicular-derived thyroid carcinoma with behavior intermediate between follicular/papillary and anaplastic carcinomas. It was described by Carcangiu in 1984, but its prognosis, classification and the origin is not yet clear. And preoperative fine needle aspiration cytology of insular carcinoma has not been satisfactory. We experienced a case of advanced thyroid insular carcinoma with invasion of the sternum. So we intend to present the case with a review of the related literatures.

This study mainly examined the unit space (room) called 'MARI' of the private houses that were built between the 19c and the early 20c in the insular areas of southwestern sea. Generally, this region has unique historicity (restructure of the insular environment in the 17c and the 18c) and geographic environment that are different from inland regions thus the environment is presumed as a related factor to developments and structures of the private houses. 'MARI' is a noticeable space that is installed in a main building without an exception even in small 3 bedroom private houses. Its nature has location and usage distinctions in an architectural plan with similar 'MARU' of inland Jeollanam-Do. There are large crocks filled with grains at MARI. Thus, MARI is a storage room. Mostly rice and various other kinds of grains are stored in the several crocks, large and small. Many household goods are kept here as well. Another peculiar function of MARI is that this space commonly enshrines ancestral tablets of three generations. Hence, MARI takes a role of a shrine of an aristocratic house from an inland region. Considering the size of the house and space, this seems to be a very unprecedented utilization of area. MARI is located at the top (at the head of the house) on the floor plan. In other words, it is located at the space in the highest rank. The importance of ancestor worship and grains is evinced architecturally. It is really interesting fact that MARI is also located within recently built modern houses (Cheongsan Island, Joyak Island, etc.). Therefore, it can be said that the unique MARI tradition of this region has an intact continuity even today. After all, MARI has a great significance as a unique unit space of insular areas of southwestern sea that is installed in the main buildings of all houses regardless of size and shape of the houses, and their insular locations.

Insular carcinoma of the thyroid(ICT) is an uncommon thyroglobulin-producing neoplasm, intermediate between well differentiated and anaplastic carcinoma. Only a few publications have addressed the fine needle aspiration cytologic(FNAC) findings from ICT. We experienced a case histologically diagnosed as ICT and with preoperative FNAC in a 52 - year - old woman. The FNAC displayed scanty colloid and abundant monomorphic follicular cells presented singly, in small loose aggregates, and in cohesive trabecular or acinar clusters. Intact insulae of tumor cells were also identified. Necrosis and mitosis were rare. Tumor cells showed round and monomorphic nuclei, finely granular chromatin, and inconspicuous nucleoli. When insular structure is identified in thyroid FNAC specimen, ICT should be included in the differential diagnosis. Herein we discuss and review the cytologic criteria for separation of ICT from other thyroid neoplasms.

Cytologic features of a poorly differentiated "insular" carcinoma of the thyroid are presented. In fine needle aspiration cytology, the aspirates were highly cellular and tumor cells were arranged in loose cluster or singly dispersed on focally necrotic background. Occasional microfollicles were evident. The tumor cells had poorly defined, scanty cytoplasm and most of the nuclei were fairly uniform with coarse chromatin pattern. A few large pleomorphic cells were also noted. The cytologic findings of the present case were correlated well with the histologic findings, which showed typical insular pattern and the presence of uniform cells with occasional pleomorphism.

저자들은 접할 기회가 흔치 않은 갑상선의 저분화암종인 일명 "도암종"의 세침흡인 세포검사 1예를 경험하고 조직학적으로 확인하였기에 문헌검색과 함께 보고하는 바이다. 흡인 도말된 세포들은 비교적 깨끗한 도말배경에 중등도 이상의 높은 세포밀도를 보였으며, 세포들은 개개로 흩어지는 양상과 판상의 군집을 이루는 양상이 어우러져 관찰되었다. 때로 세포들이 소포배열을 이루는 곳도 관찰되었다. 대부분의 종양세포들은 비교적 비슷한 크기와 모양을 나타내었으나 일부의 세포들은 현저한 다형성을 보였다. 일부의 세포에서 핵에 주름을 보였으나 소수에 불과하여 이는 어떤 갑상선병변에서나 관찰할 수 있는 비특이적 변화로 간주되었다. 세포의 겹침이 별로 없이 높은 세포밀도를 보이는 점, 세포가 개개로 흩어지는 양상과 소수 다형성이 현저한 세포의 혼재 등은 본 종양을 진단하는데 도움이 되는 소견으로 생각되며, 이러한 소견을 염두에 둠으로써 수술전 진단에 도움을 줄 수 있으리라 생각된다.

갑상선 미분화 "도암종"은 예후가 나쁘고 희귀한 종양으로 이 종양의 세침흡인 세포학적 소견에 관한 보고는 1990년 Pietribiasi에 의해 처음 기술된 이후 현재까지 8례가 있을 따름이다. 최근 저자들은 23세 여자의 좌측 경부의 갑상선 종괴로 부터 세침흡인 세포 검사를 시행하여 진단된 갑상선 도암종을 경험하여 그 세침흡인 세포학적 소견을 기술하는 바이다. 환자는 10년전부터 좌측 경부에 서서히 자라는 종괴를 호소하였으며 본 종괴에서 세침흡인 세포학적 검사를 시행하였다. 종괴의 세침흡인 도말은 세포밀도가 높았고 일정한 모양의 작고 둥근 세포들이 "도"구조 혹은 "지주" 구조를 보이며 간혹 개개로 산재되어 있는 세포 및 소포형태도 보였다. "도" 구조 및 "지주" 구조 내에는 미세한 소포형태가 관찰되었고 종양세포들의 핵은 자주 중첩되어 있었다. 갑상선 여포상 선종에서 보이는 성글게 배열된 소포구조도 드물게 관찰 되었다. 세포간의 크기나 모양은 거의 일정하였고 유사분열은 거의 관찰되지 않았다. 핵은 둥글고 뚜렷한 핵막과 미세하게 뭉친 염색질을 가지며 핵소체는 뚜렷하지 않았으며 드물게 젖빛 유리모양의 핵과 핵구가 관찰되었으나 유두상 구조는 관찰되지 않았다. 세포질의 경계는 불명확하였고 간혹 세포질내에 공포가 관찰되었다. 이상의 도암종의 세포학적 소견은 여포상 종양이나 유두상 종양들과는 구분되는 특징적인 소견이라 생각되며 세포학적 소견으로도 도암종의 진단이 가능하다고 생각된다.

Objectives : We aimed to identify the antidepressant effect of liver tonification acupuncture treatment (ACU (LT); KI10, LR8, LU8, LR4) and four gate acupuncture treatment (ACU (FG); LI4, LR3) and its brain neural activity in the normal and chronic restraint stress (CRS)-induced mouse model. Methods : Firstly, normal mice were given ACU (LT) or ACU (FG) and the c-Fos expressions in each brain region were analyzed to examine brain neural activity. Secondly, CRS was administered to mice for 4 weeks, then ACU (LT) or ACU (FG) was performed for 2 weeks. The depression-like behavior was evaluated using open field test (OFT) before and after acupuncture treatment. Then, the c-Fos expressions in each brain region were analyzed to examine brain neural activity. Results : In normal mice, ACU (FG) regulated brain neural activities in the hypothalamus, hippocampus, and periaqueductal gray. ACU (LT) changed more brain regions in the prefrontal cortex, insular cortex, striatum, and hippocampus, including those altered by ACU (FG). In CRS-induced model, ACU (LT) alleviated depression-like behavior more than ACU (FG). Also, brain neural activities in the motor cortex area 2 (M2), agranular ventral part and piriform of insular cortex (AIV and Pir), and cornu ammonis (CA) 1 and CA3 of hippocampus were changed by ACU (LT), and those of AIV and CA3 were also changed by ACU (FG). As in normal mice, ACU (LT) resulted in changes in more brain regions, including those altered by ACU (FG) in CRS model. M2, Pir, and CA1 were only changed by ACU (LT) in depression model, suggesting that these brain regions reflect the specific effect of ACU (LT). Conclusions : ACU (LT) relieved depression-like behavior more than ACU (FG), and this acupuncture effect was associated with modulation of brain neural activities in the motor cortex, insular cortex, and hippocampus.
