Background: Most cases of Graves' disease have been treated by antithyroid drugs in Korea. The major drawbacks of antithyroid drugs are the relative high rate of relapse and the inconvinience of long term therapy. Measurement of TBII and TRH stimulation test have been considered as the most reliable tests predicting relapse, but the predictive power is not high enough to use in clinical situation. This study was performed to find good prognostic indicators in Graves' disease patients after the discontinuation of antithyroid drug therapy. Subjects and methods : We restrospectively evaluated 96 patients with Graves' disease who showed normal TRH test at the end of antithyroid drug therapy and were followed for more than one year. Serum T3, T4, T3/T4 ratio, TBII, Anti-TPO Ab and TGAb levels were measured at the time of diagnosis and at the end of therapy. Two to three months after withdrawal of antithyroid medication, serum TSH and free T3 responses to TRH were examined. These parameters were compared between the relapse group and the remission group. Results : Among the 96 patients, 22 patients(22.9%) relapsed(Group Ⅱ) and 74 patients(77.1%) remained in remmision(Group Ⅰ). No significant difference was observed between the relapse and the remission group in clinical parameters, serum T3, T4, TSH, T3/T4 ratio, TBⅡ and Anti-TPO Ab determined before and after treatment. Serum TSH and free T3 levels measured after TRH stimulation were also similar in both groups. Serum TGAb levels determined at the end of treatment were significantly higher in the remission group(p<0.05). Relapse following the discontinuation of therapy occured within 24 months in 72.7% of the relapsed cases. After 24 months, relapse rate was reduced significantly. Conclusion : These results suggest that high serum TGAb levels could be a favorable prognostic indicator for the long term remission of Graves' disease treated with antithyroid drugs, and may suggest that Hashimoto's thyroiditis is combined with Graves' disease in those patients.

Malignant melanoma aries from melanocyte, which has the ability to synthesize the pigment melanin. Melanocytes are derivations of neural crest cells and widely distributed throughout all cutaneous and mucosal surfaces. Overall, 20% of all malignant melanomas arise in the head and neck, of which only 10% affect the mucous membranes. Less than 1% of all malignant melanomas affect the nasal cavity. The authors experienced a case of primary malignant melanoma originated in left nasal cavity and paranasal sinus, and the patient had been treated by wide excision of the tumor with Weber-Furguson approach and postoperative irradiation. We report a case of primary malignant melanoma on the nasal cavity and paranasal sinus of 49 years old female patient with review of literature.

김탁용,이태훈,백남인,정대균,김지영 경희대학교식량자원개발연구소 2005 硏究論文集 Vol.24 No.-

CKβ8은 CC 케모카인의 부류에 속하는 사이토카인의 일종으로, 단핵구, 호염구, 호산구, T 림프구, 자연살해세포, 수지상세포 등의 화학주성물질로 작용하는 것으로 알려져 있다. CKβ8은 염증반응 및 혈관신생 등과 같은 여러 가지 생체 반응에 역할을 하는 것으로 알려져 있다. 본 논문에서는 사람 CKβ8 유전자의 전사저해 물질을 선별하기 위하여 CKβ8/Luc 유전자를 발현하는 세포주를 확립하였다. CKβ8 유전자의 전사시작점에서 -299 부터 +10 프로모터 부위를 PCR에 의해 얻은 다음 포유세포 발현 플라스미드에 클로닝하였다. CKβ8/Lvc 유전자는 U937 세포내에서 PMA에 의해 10배 이상 발현이 증가한다. CKβ8/Luc 발현 U937 세포주는 식물 추출물에서 전사 저해제를 탐색하는데 이용되었다. 46 개의 식물 추출물 중에서 6개가 90% 이상 CKβ8/Luc의 전사를 저해하였다. 이들 물질에 대해 세포 독성 실험을 수행한 결과 그 중 한 개만이 세포 독성이 거의 없는 것으로 나타났다. 이 추출물은 붉나무에서 얻은 추출물이며 이 식물 추출물은 염증관련 질환에 대한 가능성이 있는 치료제로 이용될 수도 있을 것으로 추측된다. Ckβ8 belongs to a family of CC chemokines, which is known to act as a chemoattractant for monocytes, basophils, eosinophils, T lymphocytes, NK cells, and dendritic cells. CKβ8 is known to play roles in various biological processes such as inflammation and angiogenesis. In the present study, we developed U937 cell line expressing CKβ8/Luciferase fusion gene for screening of transcriptional inhibitors for human CKβ8 gene. Genomic sequences that contain CKβ8 promoter region from 299 to+10 nucleotide from the transcription start site was amplified by PCR and cloned into mammalian episomal plasmid. The CKβ8/Luc fusion plasmid was introduced into human promonocytic U937 cells and selected for stable U937 cells expressing the fused reporter gene. The expression of the fusion gene was induced by more than 10 folds upon treatment of phorbol myristate acetate. The stable U937 transfectant cells were used for searching transcriptional inhibitors for human CKβ8 gene from plant extracts. Among 46 plant extracts tested, six extracts exerted more than 90% inhibition of PMA-induced CKβ8 transcription. Cytotoxic tests demonstrated that one of extracts, which was extracted from Rhus chinensis Mill, had little cytotoxic effect. The extract may be used for developing a potential therapeutic agent for inflammatory diseases.

白鼠胎仔 골격발생과정에 미치는 Chlorambucil과 Tocopherol의 相互作用에 關한 實驗的 硏究

宋志南,全容赫 고려대학교 의과대학 1982 고려대 의대 잡지 Vol.19 No.3

The effect of tocopherol to the teratogenecity due to chlorambucil have been studied on the developing skeleton in prenatal offsprings from 27 mothers of albino rat through macroscopic and microscopic observations. 1. None of the significant abnormality has been observed on either macroscopic or microscopic features in the fetal group treated with single dose of tocopherol administration the mother, except, the group treated with continuous 3 doses of it to the mother, of which the measures of the weight and stature of them are generally decreased than those of the normal contrast. 2. Though the degree of teratogenecity on the developing fetal skeletal frame due to the chlorambucil is mainly depend upon the amount of the drug and the time of administration during pregnancy of mother, the highest to teratogenetic effect could be elicitable on the fetuses at the day 12th, while, none of significant effect could be detectable in the fetuses after the time of day 14th of pregnancy on the administration of the chlorambucil. 3. The protective effectiveness of the tocopherol from the teratogenecity on the fetal skeletogenesis due to the chlorambucil appears not to be efficient. On the contrary, the concomitant use of tocopheral with chlorarmbucil tends to be facilitate the teratogenetic effect of the chlorambucil, furthermore, the rate is higher against with increase of the date of pregnancy.

Objectives : Using 3-stimulus auditory "oddball" paradigm reflecting fronto/central and temporo/parietal functions Simultaneously, we examined patients with schizophrenia. Methods : fifteen patients with schizophrenia from outpatient clinic and fifteen normal controls from hospital staffs were recruited for the study. To elicit P3a and P3b, 3-stimulus auditory oddball paradigm was employed. The 3-stimulus auditory oddball paradigm was composed of standard tone (1,000 Hz, 75 dB, 80%), target tone (2,000 Hz, 75 dB, 10%) and distracter (White noise, 95 dB, 10%). Results : P3a and P3b were prominent in fronto/central and temporo/parietal areas, respectively, in both schizophrenics and normal controls. The P300 amplitude in patients with schizophrenia was reduced across P3a and P3b (p<0.01). The P300latency in patients with schizophrenia was delayed across P3a and P3b (p<0.01). Conclusion : These results were consistent with frontal and temporo-parietal lobe dysfunctions in schizophrenics. The 3-stimulus auditory paradigm could be applied for patients with schizophrenia and useful for further exploration the disorder.

도남용,나한조,이도용,허준,최지윤,이홍영,임성철 조선대학교 2000 The Medical Journal of Chosun University Vol.25 No.2

Background and Objectives : The cell-cell adhesion molecule E-cadherin is necessary for the maintenance of the epithelial cellular structure. We were designed to confirm the significance of E-cadherin as a marker for differentiation and invasiveness of squamous cell carcinoma of the larynx and hypopharynx. Materials and Methods : Our study was investigated for the immunohistochemical expression of the epithelium-specific cell adhesion molecule E-cadherin in formalin fixed paraffin embedded tissue specimen of 32 cases of squamous cell carcinoma of larynx and hypopharynx. Results : The positive expression of E-cadherin was 56.3%(18 cases) in squamous cell carcinoma of the larynx and hypopharynx. Decreased E-cadherin expression was a stastistically significant correlation with a increased grade of lymph node stage and clinical stage. Reduced expression was seen in the large tumor size and poorly differentiated tumors, but these result was not statistically significant. Conclusion : The expression of E-cadherin may be related with progression of squamous cell carcinoma of the larynx and hypopharynx. But these correlation were not sufficient for the prognostic indicators in squamous cell carcinomas of the larynx and hypopharynx.
