  • Purpose: The test had been applied for outpatient by end of 2006, however, it has been included in the medical examination since January 2007, as demand and interests have been gradually increasing in the thyroid gland disease and cancer. thus, we would necessarily evaluate usefulness of the test by comparing the number of patients who are diagnosed as "benignancy" by the medical test with the number of outpatient who attend and are diagnosed as autoimmune thyroid disease among the benign patient, in samsung medical center for a certain period. Materials and Methods: Based on the result for Anti-TPO Antibody test by RIA for the 12,937 patients in samsung medical center from October 2007 to March 2008, for six months, benignancy rate classified by sex and age is measured statistically and number of the patients who are diagnosed as autoimmune thyroid disease are kept tracked on. Results: According to the analysis of the Anti-TPO antibody test 1,135 of 12,937, which is 8.77% are benign and 218 treated patient of them, which is 19.2%, were diagnosed as autoimmune thyroid disease. Conclusions: Based on the statistics, usefulness of the test seem to have co relationship with derivation of autoimmune thyroid disease. this is 19.2% of probability relatively high. this figure, however, does not have strong relationship with specialty of the disease. Thus screening test seems to have somewhat effectiveness, considering other experiments and their margin.

  • Purpose : It is known that 3-50 percent of type 1 diabetes mellitus(T1DM) patients develop autoimmune thyroid disease. We analyzed the clinical characteristics of autoimmune thyroid disease(AITD) developed in patients with T1DM in Korean. Methods : The medical records of 139 patients, who were followed up in Department of Pediatrics, Seoul National University Children's Hospital from Jan. 1981 to Jul. 2004, were analyzed retrospectively. Results : Forty-four males and 95 females were enrolled. At least one of the autoantibodies for thyroid was positive in 54 cases. The detection rate for AITD was not correlated with sex ratio, control of T1DM, body mass index, age at diagnosis of T1DM, and familial history of thyroid disease, between two groups. In the male group, AITD was more frequently found at a younger age than in the female group. The frequency of AITD was significantly higher in the goiter group without sex differences. In the thyroid disease group, 40 patients(74.0 percent) were euthyroid, seven patients(12.9 percent) were hypothyroid, and seven patients(12.9 percent) were hyperthyroid. Conclusion : We should monitor thyroid function and autoantibodies routinely in T1DM patients who develop goiters, or young boys with T1DM.

  • This study aimed to investigate whether nociceptin contributes to the alterations in cerebral blood flow (CBF) regulation following postnatal exposure to ethanol in Sprague-Dawley rats. Animals received ethanol twice a day, 2 hr apart, on postnatal 6, 7 and 8 days. The changes in regional CBF (rCBF) in response to the changes in mean arterial blood pressure were determined at 4-, 8-, and 12-week of age by laser-Doppler flowmetry. Hypotension was induced by the gradual withdrawal of blood from arterial catheter, and the reversal of blood pressure was produced by the reinfusion of blood. Expression of nociceptin-like immunoreactivity was determined in dura mater and cerebral cortex using immunohistochemistry. Postnatal exposure to ethanol almost abolished the autoregulation of rCBF in all age groups. Pretreatment with nociceptin but not with [$Nphe^1$]nociceptin(1-13)$NH_2$, a selective competitive nociceptin receptor antagonist, 5 min prior to ethanol administration preserved the autoregulation of rCBF in all age groups. Postnatal exposure to ethanol markedly increased the expressions of nociceptin-like immunoreactivity in the dura mater and cerebral cortex, both of which were significantly inhibited by pretreatment with 7-nitroindazole monosodium salt as well as aminoguanidine 5 min prior to ethanol administration in all age groups. The values of arterial blood gas analysis were not significantly different from the basal levels in all groups. These results suggest that nociceptin deeply contributes to the compensatory mechanisms for the nitric oxide-dependent alterations in CBF autoregulation following postnatal exposure to ethanol.

  • Tokyo! is a 2008 French / Japanese / South Korean / German anthology film containing "Interior Design" by Michel Gondry, "Merde" by Leos Carax, and "Shaking Tokyo" by Joon-ho Bong, all of which were filmed in Tokyo. This cinematic triptych of three Tokyo-set stories is concerned with how the experience of self-alienation is related to urban life, that is, how to survive in a city as a self. The problem of life is the struggle for self-preservation. In Tokyo! the three film directors have shown that urban life is both self-deconstructing and self-preserving. In this paper, our purpose is to examine different modes of urban life by using two concepts reformulated by the French philosopher Jacques Derrida: the urban ipseity and auto-immunity. According to Derrida, ipseity is a system subjected to a circular structure. Such a system cannot avoid the general logic of auto-immunity; i.e., the structure of ipseity functions as both self-deconstructing and self-preserving. The three episodes contained in Tokyo! testify, each in its own way, to the function of that logic. In bringing to light the three modes of self: appropriation, dis-appropriation, and in-appropriation, we claim that the modality of urban life is confronted with the autoimmune reaction.

  • A disposable, electro-chemiluminescent immunosensor utilizing a screen-printed carbon electrode and liposome coupled to antibody as tracer has been constructed. In proportion to the analyte (Legionella species as a model) concentration, the analyte-immunoliposome complexes were transferred by the capillary action through a membrane strip to the electrode, the liposomes were lysed in the presence of detergent, and ruthenium was released for signal generation. Such performance of the immunosensor was appropriate for a point-of-care testing.

  • A 72-year-old man with general weakness visited the outpatient clinic of the hematology department. The patient had been treated under the diagnosis of autoimmune hemolytic anemia for 2 years. His hemoglobin level at the time of the visit was 6.3 g/dL, and a blood transfusion was requested to treat his anemia. The patient's blood type was A, RhD positive. Antibody screening and identification test showed agglutination in all reagent cells with a positive reaction to autologous red blood cells (RBCs). He had a prior transfusion history with three least incompatible RBCs. The patient returned home after receiving one unit of leukoreduced filtered RBC, which was the least incompatible blood in the crossmatching test. After approximately five hours, however, fever, chills, dyspnea, abdominal pain, and hematuria appeared and the patient returned to the emergency room next day after the transfusion. The $anti-Fy^a$ antibody, which was masked by the autoantibody, was identified after autoadsorption using polyethylene glycol. He was diagnosed with an acute hemolytic transfusion reaction due to $anti-Fy^a$ that had not been detected before the transfusion. In this setting, it is necessary to consider the identification of coexisting alloantibodies in patients with autoantibodies and to become more familiar with the method of autoantibody adsorption.

  • Purpose : This study analyzed the expression of HLA-DR and DQ genotypes and anti-thyroid autoantibodies[anti-thyroid peroxidase(TPO) and anti-thyroglobulin(TG) antibodies] in Korean patients with type 1 diabetes(T1DM) to investigate the susceptible HLA alleles to T1DM in Korea and the prevalence of thyroid autoantibodies and their significance for the development of thyroid disorders. Methods : A total of 59 Korean patients with type 1 diabetes[26 males, median age 13.7 years(range 5.7-29.9 years), diabetes duration 7.6 years(-1.7-22.5 years)] were enrolled in this study, and 200 healthy Koreans without a family history of diabetes were selected as a normal control for the comparison of HLA genotypes. Seventeen patients with anti-TPO or anti-TG were followed [median duration 3.96 years(1 day-10.7 years)] with measurement of anti-TPO, anti-TG, $T_3$, $T_4$ or free $T_4$, TSH levels and physical examinations. HLA-DR and DQ genotyping were done by PCR-SSO, PCR-SSCP, PCR-RFLP and PCR-SSP methods. Results : HLA analysis showed higher frequencies of HLA-DRB1*0301, *090102 and DQB1*0201, *030302 alleles, DRB1*0301/*090102, *090102/*090102 and DQB1 *0201/*030302, *030302/*030302, *0201/ *0302 genotypes in T1DM patients compared to controls(Pc<0.05). Fifteen(25.4 percent) had anti-TPO antibody, 12(20.3 percent) had anti-TG, 17(28.8 percent) had either autoantibody and 10(16.9 percent) had both autoantibodies. No clinical or subclinical hypothyroidism developed during follow-up after the first detection of anti-thyroid autoantibody. There was no significant correlation between thyroid autoimmunity and gender, onset age of T1DM, and diabetes duration, respectively(P>0.05). Conclusion : We thought this unique HLA-DR, DQ allele distribution might be an important factor for the low incidence of T1DM in Korea. And a high prevalence of thyroid autoantibodies in these populations suggests examinations of thyroid antibodies should be performed regularly. Optimal age for the initial screening and the frequency of re-screening for associated thyroid autoimmune diseases in T1DM remains to be determined through prospective follow-up.

  • 본 연구에서는 침의 면역조절작용을 통한 염증반응 억제효과를 연구하기 위하여 내독소를 주입한 흰쥐의 시상하부에서 염증반응의 중추인 방실핵의 신경활성에 미치는 영향을 관찰하였다. 흰쥐의 미정맥에 LPS와 생리식염수를 각각 주입하고 군에 따라 양측 소부(HT8)나 족삼리(ST36)에 1분간 침치료를 각각 시행하였다. C-Fos는 신경활성을 자극하는 초기단계에 발현되는 유전자로서 신경계의 특정부위의 활성도를 측정하는 지표로 널리 사용되고 있다. 본 연구자는 침자극이 LPS로 인한 염증반응에 미치는 영향과 그 기전을 알아보기 위해 면역조직화학염색의 방법을 이용하여 대뇌 시상하부의 방실핵에서 c-Fos 면역활성을 측정하였다. LPS를 주입한 군의 방실핵에서 생리식염수를 주입한 군에 비해 c-Fos 면역활성이 유의하게 증가한 반면 소부에 자침했을 때 LPS에 의해 증가된 c-Fos 면역활성이 유의하게 감소하였다. 족삼리에 자침한 군에서는 유의한 변화가 나타나지 않았다. 결론적으로 소부 침치료는 LPS로 인해 증가된 방실핵의 신경활성을 효과적으로 감소시켰고 이는 침의 면역조절 및 탁월한 염증억제 효과를 보여주는 결과일 뿐 아니라 침의 인체 항상성 유지를 통한 치료기전에 대한 향후 연구의 중요한 실마리를 제공해주고 있다고 사료된다.
