방사선에 노출된 환자에 발생한 갑상선결절의 세침흡인세포학적 소견

임성철,구자봉 朝鮮大學校 附設 醫學硏究所 2002 The Medical Journal of Chosun University Vol.27 No.2

배경 : 두경부의 각종 질환치료에 사응되는 방사선 조사는 갑상선암종의 발생위험을 높이고, 여러 가지 세포학적 변화를 초래한다고 잘 알려져 있다. 그러나, 대부분의 보고는 임상적, 방사선학적 및 병리학적 소견에 집중되고 세침흡인 세포학적 소견의 보고는 없는 실정이다. 이에 저자들은 세포학적소견을 절제생검된 조직과 연계하여 문헌고찰과함께 보고한다. 방법 : 세침흡인 세포검사는 초음파 유도하에 이루어졌고, 이어 시행된 절제 생검조직을 세침흡인 세포학적 소견에 바탕하여 고찰하였다. 결과 : 환자는 55세 여자로 21개월전에 진단된 혀의 편평세포암종으로 화학요법과 방사선요법을 받았으며, 내원 14개월전에 치료를 마쳤다. 또한 환자는 영아기에 흉선비데가 있어 방사선치료를 받은 과거력이 있다. 환자는 화학요법후 최근에 발생된 갑상선 기능저하증을 제외하고는 특별한 이상소견 없이 잘 지내왔다. 최근 갑상선 좌엽의 결절이 발견되어 세침흡인검사를 시행하였으며, 도말상 군집을 이루거나, 산재된 갑상선 여포세포들이 심한 세포학적 이형성을 보이며 관찰되었으나, 유사분열이나, 괴사의 소견은 없었다. 결론 : 세포학적 소견이 방사선조사에 의한 것에 부합되지만 여포병변의 가능성을 배제할 수 없어서 갑상선 전절제술을 시행하였는데, 피막에 잘 싸여진 여포선종이 관찰되었다. 그리고, 갑상선 전체에서 관찰되는 상피세포의 이형성은 악성변화와는 무관하며 방사선조사효과에 부합된다고 판단하였다. BACKGROUND. It is well known that any kind of radiation used to treat benign or malignant conditions in the head and neck area results in an increased risk of thyroid cancer and a cytomorphologic changes. Most of the reports have been described the clinical, radiological, and pathological features, but cytology of FNA has not. In the current study the authors report the cytologic findings in FNA specimens with literature review and attempt to correlate the cytologic features with the excisional biopsy findings. METHODS. FNA was performed with ultrasound guidance. Corresponding subsequent excisional biopsy tissue was reviewed in conjunction with the cytologic findings. RESULTS. A case of FNA cytologic atypia of the thyroid gland in radiation exposed patient. She is 55-year-old with history of a squamous cell carcinoma of the tongue, diagnosed in 21 months ago, and underwent chemotherapy, followed by radiation therapy, which was completed in 14 months ago. She also has a history of thymus enlargement in infancy, which was treated with radiation therapy. She has done well since chemotherapy except most recently developed hypothyroidism. She was found to have a left lobe thyroid nodule for which she has undergone fine needle aspiration. Smears showed clusters as well as scattered thyroid follicular cells with marked cytologic atypia. Areas with microfollicular arrangement and colloid were present. There was no evidence of mitosis or necrosis. CONCLUSION. Although the findings were compatible with radiation changes, the possibility of an underlying follicular lesion could not be excluded. She underwent total thyroidectomy and showed well-encapsulated follicular adenoma. The entire thyroid contained epithelial atypia consistent with radiation therapy effect.

This paper is concerned with the design and application of an Electro-Rheological(ER) fluid damper to suppress vibration of rotor systems. The example system at hand is flexible with a slender shaft and a thin disk, being su pported by two ball bearings. In addition, to investigate the system performances also in the high speed range, the driving torque is made to transmit through a speed increasing gear train. Along with the experiments, to predict and compare the ER damper effect, the rotor system is simulated as to its free and forced vibration characteristics. Such simulations are done by means of a finite element analysis code, which includes the mathematical model of the designed ER damper.

복숭아나무 경지삽목 번식에 있어서 삽수 굵기와 길이 및 삽수내 저장 양분 함량이 발근과 포장활착에 미치는 영향을 구명하였다. 삽수 굵기는 直徑 5∼8㎜의 삽수가 발근율이나 발근수, 발근장 등 뿌리 발달이 좋았으나 포장 활착율은 삽수재 저장양분이 많은 직경 8∼11㎜가 좋았다. 삽수 길이는 20∼30㎝ 처리가 발근율, 발근수, 발근장 등 발근력이 좋았으나 포장 활착율은 삽수재 잔존 저장 양분이 많은 30㎝ 길이가 좋았다. 삽목용 적정삽수는 8㎜ 굵기에 30㎝ 길이가 가장 효과적이었으며 포장에서 활착후 묘고, 간경 등 생육은 모든 처리에서 116㎝ 이상, 20.4㎜ 이상으로 삽목 당년에 우량묘가 생산되었다. This experiment was studied to examine the effect of cutting size and storage nutrient on rooting and survival in field using hardwood cutting of 'Sunaga Wase' peach to establish mass production system of rooted cutting. Cuttings having 5 to 8㎜ in stem diameter showed the best rooting percentage, root number and root length. In the survival in field, the stem diameter of 8 to 11㎜ showed the highest survival rate and less consumption of storage nutrient during cutting. Those hardwood cuttings of 20 to 30㎝ in stem length showed the best rooting, and higher survival in field was obtained in 30㎝ long cuttings. After transplanting rooted cuttings to field, tree height and trunk diameter of 'Sunaga Wase' peach was 116㎝ and 20.4㎜, respectively.

임성철,이용,김동출,강길,변익건,박정희,최석민 朝鮮大學校 附設 醫學硏究所 2004 The Medical Journal of Chosun University Vol.29 No.2

CD24 is a small heavily glycosylated glycosylphosphatidylinosito-linked cell surface protein, which is expressed in hematologic malignancies as well as in a large variety of solid tumors, It appears to function as a ligand of PUselectin, an adhesion molecule that is present in activated platelets and endothelial cells. The authors aimed to evaluate CD24 protein expression in adenoma and adenocarcinoma of gallbladder to correlate to clinicopathologic data. The staining- was evaluated as stainability (negative, weak-, moderate-, strong-positive) and staining' patterns (membranous vs. intracytoplasmic) for statistical analysis. A highly significant association of cytoplasmic CD24 expression with adenocarcinoma compared to the adenoma of gallbladder was demonstrated. The present study demonstrates that CD24 was abundantly expressed on adenocarcinoma rather than on adenoma, but it was not statistically significant, Interrelation between the stainability or intracytoplasmic staining of CD24 and lymph node metastasis was not statistically significant. The authors conclude that CD24 is involved in tumorigenesis of gallbladder mucosa and intracytoplasmic expression of CD24 is an important molecular marker for malignant transformation.

임성철 朝鮮大學校 附設 醫學硏究所 2005 The Medical Journal of Chosun University Vol.30 No.3

Head and neck squamous cell carcinomas (HNSCC) are characterized by a marked propensity for local invasion and cervical lymph node metastasis. The aim of this article was to review the expression of epidermal growth factor receptor (EGFR), c-erbB-2, vascular endothelial growth factor (VEGF) and matrix metalloproteinases (MMPs) in HNSCC patients and to study their possible correlation to various clinicopathologic parameters. Based on this review, the expression of EGFR, c-erbB-2, VEGF, or MMPs play important roles for tumor growth, invasion and metastasis in HNSCC. c-erbB receptors, MMPs and VEGF might aid the clinician in theselection of an appropriate therapy for individual patients and help to predict the prognosis of patients.
