연구배경:Uncoupling protein(UCP)는 미토콘드리아의 내막에 위치하는 단백질로 세포내의 과다한 에너지를 열로 발산시키는 기능을 가진다. 최근 동물의 갈색지방조직에만 존재하는 UCP와 유사성을 가진 아형들(UCP2,3)이 사람에게도 존재함이 알려져 큰 관심을 끌도 있는데 이중 UCP3는 그 발현이 골격근세포와 갈색지방조직에만 국한된다. 본 연구에서는 UCP3가 체내 인슐린 감수성을 결정하는데 가장 중요한 조직인 골격근에 국한되어 발현되는 점에 착안하여 UCP3를 골격근세포에 과발현시켰을 때 포도당 대사에 어떠한 영향이 나타나는 지를 조사하였다. 방법:25주령의 8마리의 OLETF 백서를 대상으로 하여 4마리는 골격근에 adenovirus 2mL(1×10¹²pfu/mL)를 주사하여 대조군으로 하였고 4마리는 골격근에 재조합법으로 제작된 adenovirus­UCP3 2mL(1×10¹²pfu/mL)를 주사하였다(UCP3 과발현군). UCP3를 투여한 백서에서 먹이섭취가 증가하는 경향이 있어 그 전날 대조군이 먹은 야의 먹이만큼 투여하였다. 골격근에 adenovirus를 주사한 10일 후에 euglycemic hyperinsulinemic clamp를 시행하였다. Adenovirus­UCP를 C2C12 골격근 세포에 transfection시켜 UCP3를 C2C12 골격근 세포에 transfection시켜 UPS3­C2C12를 만들고 C2C12 골격근 세포와 UPS3­C2C12 골격근 세포에서 포도당 수송 및 당원합성을 측정하였다. 결과:UCP3 과발현 OLETF에서 체중이 감소하는 경향을 보였고 인슐린 감수성이 증가하였다. C2C12세포에서 기저상태 포도당 수송은 1.28±0.17μmol/L/min였고 100nM 인슐린으로 2시간 처리한 후 2.67±0.20 μmol/L/min로 증가하였다. UCP3­C2C12 세포에서는 기저상태 포도당 수송이 3.98±0.13μmol/L/min로 증가되었고 인슐린 처리 후 5.74±0.44μmol/L/min로 증가하였다. 인슐린을 처리한 UCP3­C2C12 세포에 P13K 억제제인 wortmannin을 첨가하였을 때 포도당 수송활성이 3.81±0.20μmol/L/min로 감소하였다. 기저상태 당원합성은 C2C12 세포에서 0.25±0.01μmol/L/min였고 인슐린 처리 후 0.45±0.01μmol/L/min로 증가하였다. UCP3­C2C12 세포에서는 기저상태 당원합성이 0.62±0.01μmol/L/min였고 인슐린 처리 후 1.26±454μmol/L/min로 증가하였다. UCP3­C2C12세포에 wortmannin을 첨가하였을 때 당원합성율이 0.80±0.04μmol/L/min로 감소하였다. 결론:UCP3 과발현이 OLETF 백서에서 인슐린 감수성을 증가시켰고 골격근세포에서 포도당 수송 및 당원합성을 증가시켰다. wortmannin을 첨가하였을 때 포도당 수송 및 당원합성이 감소함으로 보아 이 과정이 인슐린 신호전달체계인 P13K에 일부 의존함을 알 수 있었다. Background : UC P3 is a mitochondrial membrane protein expressed selectively in the skeletal muscle and brown adipose tissue. Since the skeletal muscle is the main organ determining insulin sensitivity in the body, it was hypothesized that UCP3 overexpression in skeletal muscle cells would improve glucose metabolism. Methods : An adenovirus-UCP3 was produced by a recombinant DNA method. OLETF rats were divided into 2 groups. Four rats were injected with the adenovirus-UCP3 (UCP3 group) and others were injected with the adenovirus(control group) in the skeletal muscle. The UCP3 group was provided with the same quantity of food as that consumed by the control group on the previous day. Insulin sensitivity was evaluated by the euglycemic hyperinsulinemic clamp method. In a separate experiment, glucose transport and glycogen synthesis we evaluated in C2C212 cells transfected with ether an adenovirus or the adenovirus-UCP3. Results : The insulin sensitivity improved significantly and the body weight decreased in the UCP3 group. The glucose transport and glycogen synthesis were higher in the UCP3-C2C12 skeletal muscle cells at the basal state. After insulin treatment, glucose transport and glycogen synthesis were also higher in the UCP3-C2C12 cells but the increments were reduced after treatment with wortmannin, a PI3K inhibitor. Conclusion : Insulin sensitivity was higher in the UCP3-overexpressed OLETF rats in the in vivo study. UCP3 transfection also increased glucose transport and glycogen synthesis in the cultured skeletal muscle cells by a PI3K dependent mechanism(J Kor Diabetes Asso 25 :460~468, 2001).

정인경,김성훈,정재훈,민용기,이명식,이문규,유형준,안규정,노정현,김동준,김광원 대한내분비학회 2003 Endocrinology and metabolism Vol.18 No.4

연구배경 당질 코르티코이드는 당 대사에 매우 중요한 호르몬으로 내인성 당질 코르티코이드 과다상태인 쿠싱증후군에서는 말초조직에서 인슐린 저항이 증가하고 이를 보상하고자 인슐린 분비의 증가로 고인슐린혈증이 동반된다고 보고되고 있다. 하지만 생체 내에서와 달리 시험관내에서는 췌도세포에 당질 코르티코이드를 장시간 처리하면, 인슐린 분비 및 생합성이직접적으로 억제됨이 확인된 바 있어 쿠싱증후군 환자에서 당뇨병의 원인으로는 아마도 말초조직에서 증가된 인슐린 저항성 뿐 아니라 이를 충분히 보상하지 못하는 췌장에서의 인슐린 분비 저하가 같이 동반되어있지 않을까 하는 가설을 세우게 되었고, 아직까지 당질코르티코이드가 당대사 이상을 일으키는 기전에 대해 쿠싱증후군을 당대사 정도에 따라 인슐린 감수성과 분비능을 분석한 연구는 없었기에 이를 알아보고자 하였다. 방법: 삼성서울병원에서 쿠싱증후군으로 진단 받은 환자 15명을 대상으로 하였다. 이에 대한 대조군으로는 쿠싱증후군 환자와 같은 성별 그리고 체질량지수를 갖은 15명의 건강한 성인을 대상으로 비교 하였다 쿠싱증후군 환자를 대상으로 경구당부하 검사를 통해 당대사 정도를 정상군, 내당능장애군, 그리고 당뇨병군으로 나눈 후 정맥 당부하 검사를 시행하여 각군의 인슐린 저항성과 인슐린 분비능의 지표를 비교하고, 수술 후 쿠싱증후군이 완치된 상태에서 수술 전후의 당대사 지표의 변화를 조사하였다. 결과: 1) 쿠싱증후군 환자 중 정상인은 20%, 내당능 장애는 27%, 그리고 당뇨병은 53%였다. 체질량지수, 나이, 그리고 발병 기간은 세 군간에 의미 있는 차이가 없었으나, 24시간 소변검사의 코르티솔 농도는 당뇨병군에서 의미있게 높았다. 2) 정맥당부하 검사 결과, 인슐린 감수성 지표인 Sl는쿠싱증추린」서 1.58±0.10[×10^(-4)(min^(-1)(μU/mL)^(-1)]로 정상 대조군의 3.37±0.49[×10^(-4)(min^(-1)(μU/mL)^(-1)]에 비해 의미있게 낮았으나(P=0.024), 쿠싱증후군 환자 중 NGT, IGT, DM 군간에 서로 통계적인 차이는 없었다. 3) SG는 정상 대조군과 쿠싱증후군 환자간에는 의미있는 차이가 없었고, 쿠싱 증후군에 있어서 당대사가 악화될수록 감소하는 경향을 보였으나 의미있는 차이는 없었다. 4) 인슐린 분비능의 지표인 AIRg는 정상인에 비해 전체 쿠싱증후군 환자의 경우 증가하는 경향을 보였으나 의미있는 차이는 없었다. 하지만 쿠싱증후군 환자중에서 당대사 상태에 따라 NGT군은 1299 (1297∼1310)(mu/g/min ×10^(-2))로 정상 대조군(368.9±98.6[mu/g/min ×10^(-2)]) 보다도 의미있게 높았고, DM군{202.2 (91.1~371.4) [mu/g/min ×10^(-2)}은 NGT군에 비해 의미있게 낮았다(P=0.0031). 5) 15명중 현재 완치 상태에 있는 6명에 대해 수술전과 후로 비교하였다. 수술 전 당대사 상태가 1명은정상, 1명은 내당능 장애, 그리고 4명은 당뇨병이었으나 수술 후 시행한 경구 당부하 검사상 모두 정상 당대사 상태를 보였다. 6) 수술 후 완치된 환자 6명에 있어 인슐린 감수성지표인 Sl는 수술전에 중앙값이 1.22[×10^(-4)(min^(-1)(μU/mL)^(-1)]로 대조군에 비해 의미있게 감고』어 있었으나(p.0.05), 수술후 10.95 [×10^(-4)(min^(-1)(μU/mL)^(-1)]로 정상 수준으로 회복되었고(P=0.0022), 인슐린 분비능을 나타내는 AIRg [mu/g/min ×10^(-2)] 값도 정상수준으로 회복되었다. 특히 인슐린 분비능의 회복양상은 혈당농도에 따라 판이하게 나타나서, 정상과 내당능장애 상태에 있던 2명은 수술전에 1201 [mu/g/min ×10^(-2)]로 증가되어 있던 AIRg 값이 수술 후 정상 수준으로 감소하였고, 수술 전에 당뇨병 상태에 있던 4명의 경우 245.9 [mu/g/min ×10^(-2)]로 인슐린 분비능이 감고il어 있었는데 이들은 수술 후 모두 정상 수준으로 증가되었다 (P=0.0286). 결론: 쿠싱증후군 환자에서 당대사 이상은 80%로 높은 유병률을 보였다. 모든 쿠싱증후군환자에서 인슐린 감수성은 정상인에 비해 저하되어 있어 말초조직의 인슐린 저항이 선행됨을 시사하며, 인슐린 분비능은 당대사의 정도에 따라 다르게 나타났는데, 정상 당대사군에서는 인슐린의 저항성을 극복할 만큼 정상 대조군보다 더 많은 양의 인슐린 분비를 하다가 고코르티솔혈증이 심할수록 인슐린 분비능의 감소로 당뇨병으로 진행됨을 확인할 수 있었고, 이런 인슐린 저항성과 인슐린 분비장애는 수술 후 다시 회복되는 가역적인변화를 보였다. Background: Glucocorticoid plays an important role in the control of carbohydrate metabolism. Patients with Cushing's syndrome have been reported to have an increased incidence of carbohydrate intolerance due to peripheral insulin resistance and hyperinsulinemia, although the exact incidence and nature of this disorder have remained unclear. Few results have been published about insulin resistance and insulin secretion according to the level of glucose concentration, or about the reversibility of such defects in patients with Cushing's syndrome. Methods: To assess the effect of glucocorticoid on the insulin sensitivity and insulin secretion in Cushing's syndrome, 15 patients with Cushing's syndrome were classified into 3 groups (normal glucose tolerance: NGT, impaired glucose tolerance: IGT, diabetes: DM) according to the degree of glucose tolerance based on the oral glucose tolerance test (OGTT). Insulin modified, frequently sampled, intravenous glucose tolerance test (FSIGT) was performed before and after curative surgery on these patients and on 15 healthy control subjects. Data were evaluated by non-parametric statistical analysis. Results: 1) Among the 15 patients with Cushing's syndrome, 3 (20%) were NGT, 4 (27%) IGT, and 8 (53%) DM, based on OGTT. Twenty-four hour urinary free cortisol (UFC) was significantly higher in the DM group. 2) Insulin sensitivity index (SI) of Cushing's syndrome was significantly lower than that of the control group p=0.0024), but was not significantly different among the three Cushing's syndrome groups of NGT, IGT and DM. 3) Glucose mediated glucose disposal (SG) (Ed- confirm this abbreviation; it does not seem to match the definition) of Cushing's syndrome was not significantly different from that of the control group. 4) Insulin secretion (AIRg) of Cushing's syndrome tended to be high, but it was not significantly different from that of control. However, according to the level of glucose concentration there was significant difference in AlRg among the three Cushing's syndrome groups p=0.0031); AIRg of DM was significantly lower than that of NGT. 5) After surgical treatment, parameters of insulin sensitivity and insulin secretion were normalized in 6 cured patients; 1 with NGT, 1 with IGT, and 4 with DM, preoperatively. Median SI of all 6 patients was significantly improved up to the normal range postoperatively p=0.0022). Median AIRg of these 6 patients was balanced around that of normal control postoperatively p=0.0286). Conclusion: Eighty percent of patients with Cushing's syndrome had abnormality of carbohydrate metabolism. Insulin sensitivity was significantly decreased in Cushing's syndrome. Insulin secretion was significantly higher only in the NGT and IGT groups of Cushing's syndrome. As the hypercortisolemia is exacerbated, insulin secretion is significantly decreased and causes DM, suggesting that glucocorticoid has a direct or indirect toxic effect on the pancreatic beta cell (J Kor SOC Endocrinol 18:392-403, 2003).

A 60-year-old man was admitted to our hospital complaining of fever with chillness and anarexia for 12 weeks. Physical examination revealed supraclavicular lymphadenopathy and left inguinal lymphadenopathy. Abdominal CT scan showed the evidence of maked lymphadenopathy on retraperitoneal, external iliac, obturator, left inguinal, and celiac lymph nodes. A pathologic diagnosis of Ki-1(+) lymphoma was made by the biopsed supraclavicular lymph node because the node consisted of large cells with pleomorphic nuclei, scanty cytoplasm, large basophilic nucleoli, atypical vacuoli and large cells were positive for leukocyte common antigen, Ber-H2, marker, and B-cell marker.

Poly(vinylbenzyl chloride-glycidyl methacrylate)/Polyethylene Composite Anion Exchange Membranes for Vanadium Redox Battery Application

Park, Min-A,Shim, Joonmok,Park, Se-Kook,Jeon, Jae-Deok,Jin, Chang-Soo,Lee, Ki Bong,Shin, Kyoung-Hee Korean Chemical Society 2013 Bulletin of the Korean Chemical Society Vol.34 No.6

Anion exchange membranes for a vanadium redox flow battery (VRB) were prepared by pore-filling on a PE substrate with the copolymerization of vinylbenzyl chloride (VBC) and glycidyl methacrylate (GMA). The ion exchange capacity, water uptake and weight gain ratio were increased with a similar tendency up to 65% of GMA content, indicating that the monomer improved the pore-filling degree and membrane properties. The vanadium ion permeability and open-circuit voltage were also investigated. The permeability of the VG65 membrane was only $1.23{\times}10^{-7}\;cm^2\;min^{-1}$ compared to $17.9{\times}10^{-7}\;cm^2\;min^{-1}$ for Nafion 117 and $1.8{\times}10^{-7}\;cm^2\;min^{-1}$ for AMV. Consequently, a VRB single cell using the prepared membrane showed higher energy efficiency (over 80%) of up to 100 cycles compared to the commercial membranes, Nafion 117 (ca. 58%) and AMV (ca. 70%).

이 연구의 목적은 태권도 돌려차기 시 기술 수준에 따른 몸통, 골반, 지지 다리의 운동학적 변인을 비교 분석하는 데 있다. 본 연구를 위해 블랙 벨트 소지자로서 기술 수준에 따라 중급자10명, 상급자 9명이 실험에 참여하였다. 3차원 동작 분석 시스템을 사용하여 골반, 몸통, 지지다리의 방향각을 산출하였다. Start, Toeoff, MKF, Max, Impact, Min에서 그룹 간의 평균 방향각을 비교하기 위하여 독립표본 t-검정을 하였다. MKF, Impact, Min에서 골반의 좌측 기울어짐 각도가 그룹 간의 유의한 차이가 나타났다. Start와 Max에서 지지 다리의 엉덩관절 굴곡 각도와 MKF에서 지지 다리의 엉덩관절 외전 각도 사이에 유의한 차이가 있었다. 이상의 결과를 볼 때, 상급자들은 푸쉬단계에서 엉덩관절의 굴곡 각도가 증가 되었고, MKF에서는 외전 각도가 감소하였다. 또한, 스트라이크 단계에서 골반의 좌측 기울어짐 각도는 감소하였다. The study purpose was to investigate skill level differences on trunk, pelvis, and supporting leg kinematics in a Taekwondo roundhouse kick. 10 intermediate and nine expert male black-belt holders executed roundhouse kicks at a target. Orientation angles of the pelvis, trunk, and supporting -thigh, -shank, and -foot were obtained through a three-dimensional video motion analysis. Orientation angles at Start, Toeoff, Maximum Knee Flexion(MKF), Impact, Maximum angle(Max), and Minimum angle(Min) were compared between groups using independent t-tests(p<.05). Significant differences between groups were found in the pelvis left lateral tilted position at MKF, Impact, and Min; significant differences were also found in the supporting hip joint flexed position at Start and Max, and abducted position at MKF. It was concluded that higher performers increased the hip joint flexion angle in the Push phase, decreased abduction angle at MKF, and decreased the pelvis left tilted angle in the Strike phase.

Background: Focal adhesion kinase (FAK) and Src are non-receptor tyrosine kinases. FAK and Src play a critical role in inducing malignant transformation in tumor cells. Objectives: We performed immunohistochemical staining for total and phosphorylated forms of FAK and Src, to evaluate the role of FAK and Src in the development of premalignant and malignant skin lesions. Methods: A total of 59 facial skin samples (30 actinic keratoses, 10 Bowen``s diseases, 13 squamous cell carcinomas and six perilesional skins) were immunohistochemically stained for Ki-67, total (t) and phosphorylated (p) form of FAK and Src. Methods: A total of 59 facial skin samples (30 actinic keratoses, 10 Bowen``s diseases, 13 squamous cell carcinomas and six perilesional skins) were immunohistochemically stained for Ki-67, total (t) and phosphorylated (p) form of FAK and Src. Results: Cells positive for t-Src, p-Src-y530, t-FAK and pFAK-s722 were detected in premalignant intra-epithelial lesions (PELs) and squamous cell carcinomas (SCCs), but not in the perilesional skin. There was a tendency towards high correlation between Ki-67 and t-FAK or pFAK-s722, suggestive of the active role of FAK in cell proliferation. Conclusion: Our findings of higher t-Src and p-Src-y530 positive cells in PELs, as compared to SCCs (with higher Ki-67 level), are suggestive of the other role of Src in tumor formation and progression, which requires further investigation.

Backgrounds: One of the main problems conditioning the outcome of islet transplantation is the ability to separate a sufficient number of viable islets with preserved function. Islet purification is critically affected by all of the isolation stages. Thus, it is necessary to set up the standard isolation method that islets are separate well from acinar without compromising islet yield and viability. Methods: Twenty three adult mongrel dogs were used for the experiment of total pancreatectomy with islet isolation. The islets were properly isolated by a modified Recordi method. The obtained islets were further purified by centrifugation on discontinuous gradients using cell separation system (Model 2991, Cobe, Lakewood Colo). We evaluated islet number (islet equivalent number, 150 um equivalents/kg of recipient body weight, IEq/kg), purity, cell volume, viabilty, recovery rate, and comparison of outcome according to the isolation conditions. Results: 1) The mean of islet numbers before purification were 13543±9431Eq/kg, digestion times were 13.8±2.6 min., digestion temperature was 37.4±0.2℃, purity was 59.7?.0%, viability was 90.0±2.1%, cell volume was 4.7±1.1 mL, islet number after purification were 4064±361 IEq/kg, and recovery rate was 29±2.9%. 2) Isolated islet numbers were different according to the degree of pancreas distension with collagenase, digestion temperature, and digestion time. 3) The best conditions for islet isolation were above 37.5℃ in temperature at recirculation of collagenase, within 12 min in digestion time and well distended pancreas with collagenase. 4) According to multiple regression adjusted by variable factors, the degree of pancreas distension with collagenase and digestion time were independently associated factors for successful islet isolation. Conclusions: In this study, we concluded that the degree of pancreas distension with collagenase and digestion time were independent factors for successful islet isolation and the best conditions for islet isolation were above 37.5℃ in temperature at recirculation of collagenase, within 12 min in digestion time and well distended pancreas with collagenase.
