<▼1><P>Although the positive effects of recombinant fibroblast growth factor-2 (rFGF-2) in chronic obstructive pulmonary disease (COPD) have been implicated in previous studies, knowledge of its role in COPD remains limited. The mechanism of FGF2 in a COPD mouse model and the therapeutic potential of rFGF-2 were investigated in COPD. The mechanism and protective effects of rFGF-2 were evaluated in cigarette smoke-exposed or elastase-induced COPD animal models. Inflammation was assessed in alveolar cells and lung tissues from mice. FGF-2 was decreased in the lungs of cigarette smoke-exposed mice. Intranasal use of rFGF-2 significantly reduced macrophage-dominant inflammation and alveolar destruction in the lungs. In the elastase-induced emphysema model, rFGF-2 improved regeneration of the lungs. In humans, plasma FGF-2 was decreased significantly in COPD compared with normal subjects (10 subjects, <I>P</I> <I>=</I> 0.037). The safety and efficacy of inhaled rFGF-2 use was examined in COPD patients, along with changes in respiratory symptoms and pulmonary function. A 2-week treatment with inhaled rFGF-2 in COPD (<I>n</I> = 6) resulted in significantly improved respiratory symptoms compared with baseline levels (<I>P</I> <I><</I> 0.05); however, the results were not significant compared with the placebo. The pulmonary function test results of COPD improved numerically compared with those in the placebo, but the difference was not statistically significant. No serious adverse events occurred during treatment with inhaled rFGF-2. The loss of FGF-2 production is an important mechanism in the development of COPD. Inhaling rFGF-2 may be a new therapeutic option for patients with COPD because rFGF-2 decreases inflammation in lungs exposed to cigarette smoke.</P></▼1><▼2><P><B>Lung disease: Inhaling a protein might help</B></P><P>Studies on the role of the protein ‘fibroblast growth factor-2’ (FGF-2) in chronic obstructive pulmonary disease (COPD) suggest that inhaled FGF-2 could help treat the emphysema linked to smoking. Researchers in South Korea led by Young-Koo Jee at Dankook University, Cheonan, and Yeon-Mok Oh at the University of Ulsan, Seoul, studied the role of the reduced FGF-2 levels found in mice with lung inflammation caused by exposure to cigarette smoke. They also uncovered details of a protective effect of inhaled FGF-2, identifying specific cellular and lung structure changes attributed to the administered FGF-2. Reduced FGF-2 levels were also found in patients with COPD. Initial trials revealed some improvement in patients treated with FGF-2, but not at a statistically significant level. Nevertheless, the authors suggest their results justify further investigation of the protein’s therapeutic potential.</P></▼2>

The incidence of aseptic meningitis infection is ensuing and threatening the health of children. Enteroviruses are the major agents of aseptic meningitis and identification of virus has been a clue to diagnosis and epidemiology. The outbreak of aseptic meningitis occurred in Pusan, 1998. Patients were concentrated from April through November. Children were more susceptible than adults. Among 306 cases of specimens from stool, throat swab tested, only 7.2% were positive on virus isolation, 12 cases from stool and 10 from throat, respectively. All isolated 7 serotypes of viruses represented cytopathic effect on cultured cells. Three types of echovirus 6, 25, 30 and coxsackievirus B2, B3, B4, B6 were identified by neutralizing anti body test. Isolated coxsackievirus and echovirus were observed by an electron microscope with negative staining.

Background: 11β-hydroxysteroid dehydrogenase type 1 (11β-HSD1) converts inactive cortisone into cortisol, an active form, and is expressed by several tissues including the skin. Excessive active glucocorticoid (GC) deteriorates skin barrier function. Objectives: To find out if 11β-HSD1 affects on the barrier function in aged skin. Methods: We have performed human and in vivo studies. We measured cortisol in stratum corneum (SC) and oral epithelium of the elderly and young. Hairless mice were used for 11β-HSD1 immunohistochemistry staining of skin and measuring skin barrier function and serum cytokines. 11β-HSD1 knock-out (KO) mice and its wild-type were used for measuring lipid synthesis related enzyme. Results: Cortisol levels were elevated in SC and oral epithelium of the elderly rather than young. The 11β -HSD1 expression was increased in immunohistochemistry stain of aged mice skin. Aged mice showed decreased transepidermal water loss (TEWL) and SC hydration, and increased SC integrity than young. Serum inflammatory cytokines including interleukin-1α, -4, -10, -31 and tumor necrosis factor-α were increased in aged mice than young. The expressions of lipid synthesis related enzymes in epidermis were elevated in KO mice and topical 11β -HSD1 inhibitor applied mice. Conclusion: 11β-HSD1 expression is elevated in aged skin. It increases active GC and then deteriorates skin barrier function.

김현영,박기룡,김성훈,김지연,송수근,최영식,박요한 대한내분비학회 2002 Endocrinology and metabolism Vol.17 No.5

연구배경: Graves 병은 미만성 갑상선종, 갑상선기능한진, 안구침법 등을 특징으로 하는 자가면역성 질환으로, 갑상선자극호르몬 수용체에 대한 자가항체(TRAb)가 갑상선을 자극하여 발생된다. TRAb는 Graves병 환자의 약 85%이상에서 검출되며 활성화된 TRAb는 대부분 IgE로 알려져 있다. 그러나 최근 Graves병 환자의 갑상선조직과 안구조직에 IgE의 침착과 꽃가루 등에 의한 알레르기성 비염으로 인해 Graves병이 발생하거나 재발된 견우가 보고되어 Graves병의 병인에 IgE의 연관성이 제기 되고 있으나, 국내에서는 이에 대한 연구가 드물다. 본 연구에서는 Graves병에서의 혈청 IgE농도와 Graves병의 병기와의 관계 및 TRAb와 IgE 농도와의 연관성을 살펴보고자 하였다. 대상 및 방법 : 2000년 4월 1일부터 7월 1일까지 고신의료원 내분비내과를 방문한 환자 중 Graves병 46예, 만성갑상선염 6예 및 고신의료원 건강증진센터를 방문한 환자 중 갑상선질환의 병력이나 가족력 및 알레르기성 비염의 병력이 없는 35예의 정상대조군을 대상으로 연구를 시행하였다. TRAb는 갑상선자극호르몬 결합 억제 면역글로불린(TBII)으로 측정하였으며, IgE는 효소면역분석법으로 측정하였다. 결과: IgG인 TBII는 Graves병에서 만성갑상선염과 대조군에 비해 높았으며, IgE 평균농도는 Graves병에서 598.1±1112.9U/mL로 만성갑상선염 환자의 98350±79.7U/mL, 대조군 161.72±194.4U/mL에 비해 높았다(p<0.05). Graves병에서 알레르기성 비염의 발병율은 10.9%(5/46)였으며, Graves 병에서의 혈청 IgE 농도는 알레르기성 비염의 병력이 있는 경우 903.1±1152.2U/mL로 없는 경우 560.8±1117.0U/mL보다 높은 경향을 보였다. Graves병의 병기에 따른 TBII와 IgE 농도의 변화를 항갑상선제로 치료하지 않은 군(비치료군)과 치료한 군(치료군) 및 재발군으로 나누어 비교하였을 때, TBII는 치료군(7.4±18.6%)에 비해 비치료군(49.9±23.9%)과 재발군(21.1±3.1%)에서 높았으며(p<0.05), 혈청 IgE치도 치료군(233.8±432.7U/mL)에 비해 비치료군(758.6±1250.0U/mL)과 재발군(1198.5±1952.1U/mL)에서 높은 경향을 보였다. 항갑상선제로 치료한 치료기간에 따른 TBII와 IgE 농도 변화에서, TBII는 비치료군(49.9±23.9%)과 1년 미만 치료군(24.8±3.8%)에서 1년 이상 치료군(2.22±1.97%)에 비해 높았으며(p<0.05), 혈청 IgE 농도는 비치료군(758.6±1250.2U/mL)에서 1년 미만 치료한 군(158.3±91.5U/mL)과 1년 이상 치료군(252.7±483.4U/mL)에 비해 높았으나 유의하지는 않았다. 결론: Graves 병에서 IgE 농도는 증가되어 있었으며, Graves 병의 각각 다른 병기에서의 혈청 IgE 농도의 변화는 Graves qudd의 경과에 영향을 미치는 IgG인 TBII치의 변화와 유사한 경향을 보였다. 그러나 혈청 IgE와 Graves 병과의 연관성을 알아보기 위해서 IgE와 더불어 CD23항원 등의 다른 검사도 병행하는 전향적 연구가 필요할 것으로 생각된다. Background: It is widely believed that Graves' disease is and autoimmune disorder characterized by the presence of the circulation TSH receptor antibody (TRAb). The majority of the activity of TRAb is of the immunoglobulin G(IgG) class. However, other immunoglobulin such as immunoglobulin E(IgE), may play a rloe in the activity. IgE accumulation has been reported to occur in the thyroid gland and ocular muscles of subjects with Graves' disease. Furthermore, it has been noted that recurrence of Graves' disease can be induced by and allergy to pollen. Because an allergy to pollen is commonly associated with IgE, IgE might play a role in the induction of Graves' disease. Therefore, investigated whether IgE was elevated in Graves' disease, and evaluated the potential relationship between the levels of TRAb and IgE Graves' disease. Methods: Forty-six patients with Graves' disease, and 6 with chronic thyroiditis, diagnosed at the Kosin Medical Center between April, 2000 and July, 2000 were included in this study. Thirty-five persons without thyroid disease or a history of allergic rhinitis were used as normal controls. The level or TRAb was measured using thyrotropin binding inhibitory immunoglobulin (TBII). Serum total IgE was measured using as enzymeimmunoassay method. Test for thyroid function, TBII and total IgE were performed in all cases, and the results statistically analyzed. Results: TBII, as IgG, and the serum IgE level were higher in the patients with Graves' disease, and the levels of the latter were 598.1±1112.9U/mL, 98.5±79.7U/mL and controls 161.7±194.4U/mL in the Graves' patients, those with thyroiditis and the controls, respectively (p<0.05). The prevalence of allergic rhinitis in Graves' disease was 10.9%. The serum IgE level in Graves' disease with, and without, allergic rhinitis were 903.1±1152.2U/mL and 560.8±1117.0U/mL, respectively, although there was no significancant difference between the two groups. According to the clinical stage, the serum TBII level was higher in the untreated Graves', and relapsed patients 49.9±23.9% and 21.1±3.1%, respectively, than in the treated group, 7.4±18.6% (p<0.05). The serum IgE level was higher in the untreated Graves' and relapsed patients 758.6±1250.2U/mL and 1198.5±1952.1U/mL, respectively, than in the treated group 233.8±432.7U/mL, although this was not significant. According to the duration of treatment, the serum TBII levels were higher in the untreated Graves' patients, and those treated for less than 1 year, than in those treated for more than 1 year, with values of 49.9±23.9, 24.8±3.8 and 2.22±1.97%, respectively (p<.05). The serum IgE level was higher in the untreated Graves' disease (758.6±1250.2U/mL) than in the groups treated for less than 12 months (158.3±91.5U/mL) and more than 12 months (252.7±483.4U/mL), but the differences were not significant. Conclusions: The concentration of IgE was high in Graves' patients, and although not statistically significant, the serum igE level in Graves' patients with allergic rhinitis was higher than those without. With regard to the clinical stage of Grave's disease, the change in the IgE level tended to follow that of the TBII. Further study will be required to define the possible role of IgE in the pathogenesis in Graves' disease (J Kor Soc Endocrinol 17:640∼648, 2002).

Radiofrequency ablation(RFA), as a form of minimally invasive therapy for hepatocellular carcinoma, has become an important treatment modality. Because of limitation of surgery, RFA has become standard therapy for hepatocellular carcinoma in some situations. But there are some complications of RFA such as bleeding, infection, hematoma, adjacent organ thermal damage including intestinal perforation, needle track seeding, and so on. There are few reports in the literature that systematically evaluate the incidence of needle tract seeding and its associated risk factors. And only 2 cases of needle tract seeding of hepatocellular carcinoma after RFA were reported in Korea. We report a case of needle tract seeding of hepatocellular carcinoma after RFA.

Background : The safety and effectiveness of influenza vaccine are well known in developed country. The influenza vaccination has been recommended as one of the tentative immunization schedule for indicated persons since 1997 in Korea. But there are still no available data about them, even though nearly 5 million doses of influenza vaccine were used in 1997-1998 season. So it is immediately needed to investigate the safety. efficacy and immunogenicity of influenza vaccine among Korean. Methods : We studied the clinical efficacy of influenza vaccine by monitoring Occurrence of influenza-like illness in influenza risk group(vaccination ; 300, non-vaccination; 215) from December in 1997 to March in 1998. We used the split quadrivalent influenza vaccine containing 15 microgram of hemagglutinin of A/Beijing/262/95(HlNl), A/Wuhan/359/95(H3N2), B/Mie/1/93 and B/Guangdong/5/94. Hemagglutination inhibition(HA1) antibody titers were determined before immunization and 1 months after vaccination And we evaluated adverse effect of influenza vaccination at 7 days after vaccination. Results : Influenza vaccination was associated with si@icant reductions in influenza-like spptoms(vaccination group; 28.35%, non-vaccination group, 35.88%, p=0.001). The preventive effect of influenza-like i3lne.s among influenza risk goup was 20.97%. And immunogenicity of influenza A and B exceeded all of the European licensure criteria for immunogenicity except postvaccination proportion of titers 240 of B/Guangdong/5/94 strain. And the adverse effects were mainly local injection site problem and no serious adverse effect was noted. Conclusion : Split influenza vaccine is safe, inmunogenic and eff'tive in influenza risk group in Korea.

Backgrounds and Objectives: Vascular dementia is a group of dementing disoders arising from various stroke syndrome. Among these. subcortical ischemic vascular dementia (SIVD) is regarded as a relatively distinct clinical entity. However, MRI patterns of SIVD are not homogenous. In some patients, lacunes are dominant, and in others, subcortical white matter changes are. This study was designed to compare risk factor profiles between SIVD with and without multiple lacunes. Methods: We divided 47 subjects (22 males, mean age. 68 years) recruited from VADAPET (Multicenter Trial For Evaluation Of The Changes In the PET Images Of Subcortical Vascular Dementia Patient) study into two groups one with more than 5 lacunes in deep gray matter (lacune group) and the other with 5 or less(non-lacune group) Clinical characteristics and laboratory findings of two groups were compared. Results: Nineteen of 47 patients (40%) belonged to the lacune group. The lacune and non-lacune groups d d not differ in the following variables: age, hypertension, diabetes mellitus, hyperlipidemia heart disease, history of stroke or TIA, history of trauma or major surgery, family history of hypertension stroke, or dementia, age at diagnosis of dementia, body mass index, white blood cell count, ESR, CRP, fibrinogen, hemoglobin A1C, total cholesterol. LDL cholesterol creatinine, proteinuria, glucosuria, and microhematuria. However, male sex, smoking alcohol. hemoglobin, and HDL cholesterol were possibly associated more with lacune group SIVD than with non-lacune group (p<0 1) Multivariate analyses revealed that smoking, hemoglobin, and HDL cholesterol were independent predictors of SIVD with multiple lacunes Conclusion: Our study suggests that SIVD with multiple lacunes may be significantly different in smoking habits hemoglobin, and HDL cholesterol from SIVD without multiple lacunes.
