Many of the growth-promoting properties of growth hormone(GH) are mediated by insulin-like growth factor-I(IGF-I), a highly conserved circulating 70-amino acid peptide. Recent studies have shown that multiple mechanisms influence IGF-I gene expression, including transcription from two promoters, alternative RNA splicing, and variable polyadenylation. In thyroid tissue, thyroid stimulating hormone(TSH) and IGF-I are the most possible candidates for follicular cell proliferation and hypertrophy. Actually IGF-I had autocrine and paracrine effect for tissue growing. We prepared thyroid tumor tissue mRNAs using single step method for detecting IGF-I levels according to different tissues, i.e., thyroid adenoma or papillary thyroid carcinoma. We used Northern blot analysis for IGF-I mRNA and RNase protection assay (RPA) for IGF-I transcription start sites. For Northern blot, we used whole human IGF-I cDNA as a DNA probe and for RPA, we used IGF-I exon 1 containing noncoding promoter 1 as a riboprobe. We got good RNA bands from Northern blot analysis around 1 kb (IGF-IA) and 7.5 kb (IGF-IB) region. To clarify the amount of both IGF-IA and IB mRNAs, we measured autoradiographied signal of IGF-I mRNAs bands using densitometer. In IGF-IA signals, there's no change among liver and thyroid tissues, but in case of IGF-IB mRNA bands, the signal was markedly increased in thyroid carcinoma tissues than that of normal thyroid tissue (85% vs 14%). In the study of RPA, all thyroid tissues used the same transcription start sites as those of liver's. We concluded that that this different regulation of IGF-I mRNA was originated from tissue specificity. That meant some tissue specific transcription factor/s were related to tissue IGF-I expression.

오승준,김영설,박철영,김덕윤,김성운,양인명,김진우,최영길,팽정령,정경천 대한비만학회 2000 The Korean journal of obesity Vol.9 No.2

연구배경 : 혈전현상을 특징으로 하는 질환에서는 Plasminogen activator inhibitor-1 (PAI-1) 이 높은 활성도를 보이는데, PAI-1 치는 당뇨병, 심근경색증, 비만 등에서 높다고 밝혀진 바 있다. 또한 당뇨병 환자들의 합병증의 주요한 병인은 죽상경화증으로 혈전현상이 특징인 질환에서 증가하는 PAI-1이 당뇨병 환자에서 높다. 목적 : 정상인에서의 PAI-1 유전자 촉진자의 유전자형의 분포 및 혈액농도를 관찰하고, 당뇨병 및 뇌혈관 질환 환자군에서의 PAI-1 유전자 촉진자 유전자형의 분포 및 혈액농도를 측정하여 정상인과 차이점을 알아본다. 당뇨병 환자군에서의 혈장 PAI-1 치와 인슐린 저항성, 전구 인슐린 등과의 상관관계를 살펴보고, 인슐린저항성과 대혈관질환의 지표로 사용될 수 있는지 알아보았다. 방법 : 대상으로는 정상인 76명, 제2형 당뇨병 환자 56명, 뇌혈관질환이 동반된 제2형 당뇨병 환자 48명, 뇌혈관질환 환자 51명을 선택하여, 환자의 혈액에서 인슐린, 공복시 혈당, 전구인슐린, 중성지방, 총콜레스테롤 및 기타 생화학 검사 및 이학적 검사를 시행하였다. 환자의 DNA를 채취하여 전사개시 -675bp를 포함하는 대립형질 특이 시발체를 사용하여 중합효소 연쇄 반응을 실시하여, 그 유전자형을 판독하였다. 결과 : 정상 대조군 76명 (46.4±11.1세), 2형 당뇨병 환자 56명 (58.3±12.6세), 뇌경색증 환자 51명 (63.1±13.2세) 대상으로 하였다. PAI-1 촉진자 유전자형의 (4G/4G, 4G/5G, 5G/5G)빈도는 정상 대조군이 각각 23.7%, 75.0%, 1.3%, 뇌경색 환자군이 19.6%, 66.7%, 13.7%, 뇌경색이 동반된 당뇨병 환자군이 33.3%, 58.3%, 8.3% 였다. (X2=12.6, p=0.05). 이러한 사실은 서구인에 비해 4G/4G, 5G/5G 동형 유전자형이 낮은 결과였다. 각 군별 혈장 PAI-1 농도는 정상 대조군 13.4, 1.8 ~ 65.2 ng/mL (중앙값 , 범위 ) 2형 당뇨병 환자군 14.4, 2.9 ~ 47.8 ng/mL, 뇌경색 환자군 21.9, 6.2 ~ 154.7 ng/mL , 뇌경색이 동반된 2형 당뇨병 환자군 28.8, 3.2 ~ 139.3 ng/mL 로 차이를 보였다 (p=0.000). 전체 대상에서 PAI-1 촉진자 부위의 유전자형에 따른 PAI-1 활성도와 항원 농도는 차이를 보이지 않았다. 그러나 PAI-1 활성도는 혈중 중성지방, 전구인슐린, 체질량지수와 독립적인 상관관계를 보였다 (p=0.000, p=0.000 and p=0.005). 결론 : 결론적으로 PAI-1 촉진자 부위의 유전자형은 뇌경색증의 지표는 아니며, PAI-1 활성도를 결정짓는 인자는 유전적 요인보다는 혈중 중성지방, 전구 인슐린, 체질량지수와 같은 대사적 요인으로 생각된다. Plasminogen activator inhibitor-1 (PAI-1) is known be related to insulin resistance and several components of the large vascular disease. Notably, the high frequencies of diseases such as coronary heart disease or stroke are related to type 2 diabetes complications. We studied to find out whether the PAI-1 promother genotype could be a marker for cerebral infarction in type 2 patients. Subject patients were; 56 type 2 diabetics (age 58.3±12.6), 51 patients with cerebral infarction (age 63.1±13.2), 48 type 2 diabetics with cerebral infarction (age 64.8±9.3) , and 76 healthy control (age 46.4±11.1). The 4G/5G genotype of PAI-1 promoter was evaluated by polymerase chain reaction and endonuclease digestion. PAI-1 promoter genotype frequency (4G/4G, 4G/5G, 5G/5G) was 23.7%, 75.0% and 1.3% in healthy control, 17.9%, 67.9% and 14.3% in type 2 diabetes patients, 19.6%, 66.7% and 13.7% in cerebral infarction patients, 33.3%, 58.3% and 8.3% in type 2 diabetics with cerebral infarction (X^2=12.6, p=0.05). This finding is lower in frequency of 5G/5G homozygote than that reported in Caucasians. The plasma PAI-1 concentrations according to the disease were 13.4, 1.8 ~ 65.2 ng/mL (median, range) for healthy control, 14.4, 2.9 ~ 47.8 ng/mL for type 2 diabetes, 21.9 6.2 ~ 154.7 ng/mL for cerebral infarction , and 28.8, 3.2 ~ 139.3 ng/mL, for cerebral infarction with type 2 diabetes (p=0.000). In the all subjects, PAI-1 concentration and activity of PAI-1 promoter genotype did not show any significant difference. However, the PAI-1 activity was independently associated with serum triglyceride level, plasma proinsulin and BMI (p=0.000, p=0.000 and p=0.005 respectively). We concluded that PAI-1 genotype is not a marker for the cerebral infarction ; however, the genotype is related to PAI-1 concentration , and therefore it seems to be that metabolic factors such as triglyceride level or plasma proinsulin or BMI are more in relations with determining the PAI-1 concentration than the genotype.

남기덕,김영설,박철영,오승준,김덕윤,우정택,김성운,양인명,김진우,최영길 대한당뇨병학회 2002 Diabetes and Metabolism Journal Vol.24 No.6

연구배경:인슐린저항성은 제2형 당뇨병과 심혈관질환의 주요한 위험 인자로 성호르몬과 상호 관계가 있다고 알려져 있다. 그러나 여성과는 달리 남성에서는 연령과 인슐린저항성에 따른 유리 테스토스테론과 성호르몬 결합 글로블린 농도의 변화에 대한 연구가 부족한 실정이다. 그러므로, 본 저자등은 제2형 당뇨병 남성 환자에서 정산인과 비교해서 유리 테스토스테론과 성호르몬 결합 글로블린 농도를 측정하고 연령에 따른 변화 정도를 알아보고자 하였다. 방법:대상 환자 모두에서 연령과 체질량지수, 총 콜레스테롤, 중성지방, 공복혈당과 인슐린 농도를 측정하였다. 혈중 유리 테스토스테론 농도는 방사면역측정법(radioimmunoassay)을 이용해서 측정하였고, 혈중 성호르몬 결합글로불린은 면역방사계측측정법(immunoradiometric assay)을 이용해서 측정하였다(Diagnostic System Laoratories, Wbster, TX, USA). 결과:1)제2형 당뇨병 남성 환자에서 정상 대조군 남성에 비해 성호르몬 결합글로불린은 104.1±35.0 vs 25.7±3.5 mole×10??로 의미 있게 높았으나(p<0.001), 유리 테스토스테론은 13.7±9.5 vs 13.6±6.5 ng/dL로 차이가 없었다. 2)연령과 성호르몬 결합 글로블린 사이의 상관 계수는 제2형 당뇨병 남성 환자에서 0.40로 중등고의 양의 상관 관계를 보였고(p<0.001), 정상 대조군 남성에서 0.11로 유의한 상관 관계를 보이지 않았다. 연령과 유리 테스토스테론 사이의 상관 계수는 제2형 당뇨병 남성 환자에서 0.08, 정상 대조군 남성에서-0.17로 모두에서 유의한 상관 관계를 보이지 않았다. 3)연령과 체질량지수를 보정한 후에 제2형 당뇨병 남성 환자와 정상 대조군 남성에서 혈중 인슐린 농도, 유리 테스토스테론과 성호르몬 결합 글로블린 사이에는 상관 관계가 없었다. 결론:제2형 당뇨병 남성 환자에서 정상 남성에 비해 성호르몬 결합 글로블린 농도가 증가되어 있었으며, 유리 테스토스테론은 차이가 없었다. 연령이 증가함에 따라 성호르몬 결합 글로블린이 제2형 당뇨병 남성 환자에서 정상 남성에 비해 증가 폭이 의미있게 컸으며, 유리 테스토스테론은 변화가 없었다. Background: Insulin resistance is a risk factor for cardiovascular disease and type 2 diabetes mellitus. There are many previous studies indicating that insulin lowers serum sex hormone-binding globulin levels, and there is inverse correlation between insulin resistance and serum sex hormone-binding globulin levels in women. However, in men, a limited number of studies are available to explain the effect of sex hormone on age and insulin. Therefore, the present study was undertaken to investigate the relationship among free testosterone, hormone-binding globulin and age in type 2 diabetic men and control subjects. Method: Age, body mass index, total cholesterol, triglyceride, fasting blood sugar, and insulin concentrations were examined on 89 type 2 diabetic men and 47 control subjects. The free testosterone level was measured by commercially available double-antibody system (Radioimmunoassay). The sex hormone-binding globulin level was also measured by commercially available double-antibody system(Immunoradiometric assay). Results: 1) Sex hormone-binding globulin level was significantly increased in patients with type 2 diabetes. However, there was no significantly difference in free testosterone level between the two groups. 2) Sex hormone-binding globulin was positively correlated with age (r=0.4, p <0.001) in patients with type 2 diabetes. Sex hormone-binding globulin and free testosterone were not correlated with age in control sujects. 3) Free testosterone and sex hormone-binding globulin concentrations were not significantly related to serum insulin concentration after adjusting for age and body mass index. Conclusions: We observed increased sex hormone-binding globulin concentration in diabetes man, and was a positively related to age. Further studies are needed to understand the relationships between age, insulin resistance, testosterone, and sex hormone-binding globulin concentrations(J Kor Diabetes Asso 24:699~707,2000).

Diabetes Mellitus (DM) is a syndrome accompanied with the abnormal secretion or function of insulin, a hormone that plays a vital role in controlling the blood glucose level (BGL). Type 1 and 2 DM are most common form and the prevalence of the latter is recently increasing. The aim of this article was to assess whet her Type 2 DM could act as a predisposing risk factor on the pulpo-periapical pathogenesis. Previous literature on the pathologic changes of blood vessels in DM was thoroughly reviewed. Furthermore, a histopathologic analysis of artificially-induced periapical specimens obtained from Type 2 diabetic and DM-resistant rats was compared. Histopathologic results demonstrate that the size of periapical bone destruction was larger and the degree of pulpal inflammation was more severe in diabetic rats, indicating that Type 2 DM itself can be a predisposing risk factor that makes the host more susceptible to pulpal infection. The possible reasons may be that in diabetic state the lumen of pulpal blood vessels are thickened by atheromatous deposits, and microcirculation is hindered. The function of polymorphonuclear leukocyte is also impaired and the migration of immune cells is blocked. leading to increased chance of pulpal infection. Also, lack of collateral circulation of pulpal blood vessels makes the pulp more susceptible to infection. These decrease the regeneration capacity of pulpal cells or tissues, delaying the healing process. Therefore, when restorative treatment is needed in Type 2 DM patients, dentists should minimize irritation to the pulpal tissue under control of BGL. 당뇨(Diabetes Mellitus)란 혈당을 조절하는 인슐린의 분비나 기능에 장애를 야기하는 질환으로 인슐린 의존성 여부에 따라 제 1 형과 제 2 형으로 분류된다. 본 종설은 최근 증가 추세에 있는 제 2 형 당뇨가 치수 치근단 병소의 병인 과정에 전구 위험 요인으로 작용할 수 있는지를 평가 하고자 문헌고찰을 통해 당뇨의 병인 과정에서 특징적으로 나타나는 혈관 합병증에 관해 알아보고, 부가적으로 제 2 형 당뇨 쥐 모델에서 인위적인 치수감염 후 얻은 치근단 조직의 조직병리학적 분석을 시행하였다. 조직학적 관찰 결과 제 2 형 당뇨 쥐에서 대조군에 비해 치수 치근단 병소의 크기가 증가하였고, 치수 염증 반응도 심하게 나타난 것으로 보아 당뇨 자체가 숙주를 감염에 취약한 상태로 만드는 전구 위험요소로 작용하였음을 알 수 있었다. 이러한 이유로는 첫째, 당뇨 시 전반적으로 나타나는 혈관 내 죽상 침착(atheromatous deposits)에 의해 혈관 내벽의 두께가 두꺼워져 미세 순환의 장애는 물론 탐식 세포의 기능 저하, 면역 세포의 혈류 이동이 차단되어 치수 감염 시 쉽게 치근단 병소로 이환될 가능성이 높고, 둘째 치수 혈관에서 특징인 측부 순환(collateral circulation)의 부재에 따른 살균성 다형핵 백혈구의 활동 억제를 포함한 미세 혈관계의 취약성으로 인해 치수 조직의 재생능이 저하되어 추가적인 감염원의 공격에 대한 방어 및 치유 저하를 더욱 심화시키기 때문인 것으로 사료된다. 따라서 제 2 형 당뇨 환자의 수복치료 시 치과의사는 당뇨 조절 하에서 치수 조직의 자극을 최소화하기 위한 세심한 처치가 필요하다.

윤규석,김덕언,최태열 대한감염학회 1993 감염 Vol.25 No.1

An immunotyping of 27 strains of Chlamydia trachomatis isolated from patients with non-gonococcal urethritis or pelvic inflammatory diseases in Korea was achieved in dot-enzyme linked immunosorbent assay (dot-ELISA) with monoclonal antibodies. Monoclonal antibodies were produced with standard techniques by immunization of Balb/c mice and fusion with SP 2/0 myeloma cell. Seven type-specific (D,E,F,H,I,J,L₂), 2 subspecies-specific (B-complex, C-complex) and species-specific (HMC 1-1) monoclonal antibodies were used for immunotyping. Immunotyping of 12 control strains and 27 clinical strains isolated in Korea was studied by using dot-ELISA. Species-specific (HMC 1-1) monoclonal antibody reacted with all control strains and 27 isolated. Subspecies-specific (B-complex) monoclonal antibody reacted with B/HAR-36, Ba/Aphach-2, D/UW-3Cx, E/Bour, LGV type Ⅰ/440, LGV type Ⅱ/CDC control strains and 19 isolates. Type-specific monoclonal antibody of D was reacted with D/UW-3/Cx control strain and 10 isolates. E type-specific monoclonal antibody racted with E/Bour control strain and 6 isolates. F type-specific monoclonal antibody reacted with 5 isolates. Three isolates which racted with subspecies-specific monoclonal antibody didn't react with any type-specific monoclonal antibodies. Subspecies-specific (C-complex) monoclonal antibody reated with A/HAR-13, C/CDC, H/UW-43/Cx, J/UW-36/Cx control strains and 2 clinical isolates, but the isolates did not react with any type-specific monoclonal antibodies. One of 27 clinical isolates reacted with any type-specific monoclonal antibodies. One of 27 isolates reacted with species-specific (HMC 1-1) monoclonal antibody didn't react with any other subspecies-and type-specific monoclonal antibodies. In conclusion, the major immunotypes of C.trachomatis from urogenital system in Korea were D, E and F, and dot-ELISA with monoclonal antibody may contribute for immunotyping as a simple and specific technique.
