      • Medicinal Chemistry : EVALUATION OF CADMIUM-INDUCED NEPHROTOXICITY USING URINARY METABOLOMIC PROFILES IN SPRAGUE-DAWLEY MALE RATS

        ( Yu Kyung Lee ),( Eun Young Park ),( Shi Won Kim ),( Ji Yeon Son ),( Tae Hyung Kim ),( Won Gu Kang ),( Tae Chun Jeong ),( Kyu Bong Kim ),( Seung Jun Kwack ),( Jae Won Lee ),( Suh Mann Kim ),( Byung M 영남대학교 약품개발연구소 2015 영남대학교 약품개발연구소 연구업적집 Vol.25 No.-

        The aim of this study was to investigate urinary metabolomics profiles associated with cadmium (Cd)-induced nephrotoxicity and their potential mechanisms. Metabolomic profiles were measured by high-resolution 1H-nuclear magnetic resonance (NMR) spectroscopy in the urine of rats after oral exposure to CdCl2 (1, 5, or 25 mg/kg) for 6 wk. The spectral data were further analyzed by a multivariate analysis to identify specific urinary metabolites. Urinary excretion levels of protein biomarkers were also measured and CdCl2 accumulated dose-dependently in the kidney. High-dose (25 mg/kg) CdCl2 exposure significantly increased serum blood urea nitrogen (BUN), but serum creatinine (sCr) levels were unchanged. High-dose CdCl2 (25 mg/kg) exposure also significantly elevated protein-based urinary biomarkers including osteopontin, monocyte chemoattractant protein-1 (MCP-1), kidney injury molecules-1 (Kim-1), and selenium-bingding protein 1 (SBP1) in rat urine. Under these conditions, six urinary metabolites (citarate, serine, 3-hydroxyisovalerate, 4-hydroxyphentllactate, dimethylamine, and betaine) were involved in mitochondrial energy metabolism. In addition, a few number of amino acids such as glycine, glutamate, tyrosine, proline, or phentlalanine and carbohydrate (glucose) were altered in urine afrer CdCl2 exposure. In particular, the metabolites involved in the glutathione biosynthesis pathway, including cysteine, serine, methionine, and glutamate, were markedly decreased compared to the control. Thus, these metabolites are potential biomarkers for detection of Cd-induced nephrotoxicity. Our results further indicate that redox metabolomics pathways may be associated with Cd-mediated chronic kidney injury. These findings provide a biochemical pathway for better understanding of cellulat mechanism underlying Cd-induced renal injury in hunmans.

        김소월 「시혼」의 이기론적(理氣論的)고찰

        김지혜 ( Ji Hye Kim ),권유성 ( Yu Seung Kwon ) 한국문학언어학회( 구- 경북어문학회) 2010 어문론총 Vol.52 No.-

        This study aims at clarifying that Kim, So-Wol`s poetics is based on LiKi(理氣)philosophy. And this is to show the distinction between Western ideas like Romanticism which is accepted by Kim-uk and So-Wol`s traditional poetics. The results are as follows. First, So-Wol is realized paradoxical sense which can find out positive meaning from negative thing and overcome Western dichotomy by LiKijimyo(理氣之妙) principal means that Li(理) as Hyungisanja(形而上者: metaphysical thing) and Ki(氣) as Hyungihaja (形而下者: physical thing)are neither divided nor united. Second, So-Wol emphasizes that immutable character of Sihon(詩 魂) on his poetics because he wants to show Li`s character as inevitable cause and right. As he authorizes Sihon(詩魂) ontological and axiological character of Li, Sihon(詩魂) has Good truth and thereby has good effect for society. Unlike Kim-uk`s romanticism, to display subjectivity on So-Wol`s poetics is based on LiKi philosophy has a effect for society, because the subjectivity has a moral sensibility. Last, like Li and Ki, Sihon(詩魂) is manifested on poetry by Umyoung(陰影), so poetry is valuated by not Sihon but Umyoung. But So-Wol contradicted himself by asserting that Umyoung(陰影) isn`t discussed merits and demerits. This is explained by considering LiKijimyo(理氣之妙). Ki is a manifestation of Li, therefore when we see poetry as Ki with view is based on authenticity, Ki is not a thing of judgement. But when we poetry with view is based on substantiality, Ki is a thing of judgement. In conclusion, So-Wol intended to include not only eternal nature but also substantiality on modern poetry with LiKi(理氣) philosophy.

        Protective effect of Korean Red Ginseng against FK506-induced damage in LLC-PK1 cells

        Dahae Lee,Ki Sung Kang,Jae Sik Yu,Jung-Yoon Woo,Gwi Seo Hwang,Dae-Woon Eom,Seung-Hoon Baek,Hye Lim Lee,Ki Hyun Kim,Noriko Yamabe 고려인삼학회 2017 Journal of Ginseng Research Vol.41 No.3

        Background: Compound FK506 is an immunosuppressant agent that is frequently used to prevent rejection of solid organs upon transplant. However, nephrotoxicity due to apoptosis and inflammatory response mediated by FK506 limit its usefulness. In this study, the protective effect of Korean Red Ginseng (KRG) against FK506-induced damage in LLC-PK1 pig kidney epithelial cells was investigated. Methods: LLC-PK1 cells were exposed to FK506 with KRG and cell viability was measured. Western blotting and RT-PCR analyses evaluated protein expression of MAPKs, caspase-3, and KIM-1. TLR-4 gene expression was assessed. Caspase-3 activities were also determined. The number of apoptotic cells was measured using an image-based cytometric assay. Results: The reduction in LLC-PK1 cell viability by 60mM FK506 was recovered by KRG cotreatment in a dose-dependent manner. The phosphorylation of p38, p44/42 MAPKs (ERK), KIM-1, cleaved caspase-3, and TLR-4 mRNA expression was increased markedly in LLC-PK1 cells treated with 60mM FK506. However, with the exception of p-ERK, elevated levels of p-p38, KIM-1, cleaved caspase-3, and TLR-4 mRNA expression were significantly decreased after cotreatment with KRG. Activity level of caspase-3 was also attenuated by KRG cotreatment. Moreover, image-based cytometric assay showed that apoptotic cell death was increased by 60mM FK506 treatment, whereas it was decreased after cotreatment with KRG. Conclusion: Taken together, these results suggest that the molecular mechanism of KRG in the FK506-induced nephrotoxicity may lead to the development of an adjuvant for the inhibition of adverse effect FK506 in the kidney.

        비파괴 측정을 위한 근접장 마이크로파 현미경 연구

        김주영,김송희,유현준,양종일,유형근,유경선,김승완,이기진 한국비파괴검사학회 2004 한국비파괴검사학회지 Vol.24 No.5

        근접장의 특성과 근접장 마이크로파 현미경의 배경이론을 설명하였고 유전체 공진기 제작에 앞서 HFSS (high frequency structure simulator)를 이용한 모의 시뮬레이션을 기술하였다. 이것을 바탕으로 원통형 유전체 공진기를 제작하여 금속탐침과 결합한 근접장 마이크로파 현미경(near field scanning microwave microscope : NSMM)을 구성하였다. 제작한 유전체 공진기의 특성은 HFSS를 이용하여 모의 실험한 결과와 비교하였다. Tip의 기하학적 모양에 따른 공간분해능과 감도(sensitivity)를 연구하였고 contrast가 가장 좋은 hybrid tip을 개발하였다. 전도도가 서로 다른 금속시료에 따른 NSMM의 반사계수의 변화를 측정하였고 실험결과와 이론적 시료의 임피던스를 비교하였다. 마지막으로 유전체 공진기를 이용한 NSMM으로 공간 분해능이 1μm의 Cr과 NiFe 패턴의 이미지를 비접촉, 비파괴방법으로 얻었다. We described a near-field scanning microwave microscope which uses a high-quality dielectric resonator with a tunable screw. The operating frequency is f = 4.5 5 GHz. The probe tip is mounted in a cylindrical resonant cavity coupled to a dielectric resonator. We developed a hybrid tip combining a reduced length of the tapered part with a small apex. In order to understand the function of the probe, we fabricated three different tips using a conventional chemical etching techique and observed three different NSMM images for patterened Cr films on glass substrates. We measured the reflection coefficient of different metal thin film samples with the same thickness of 300 nm and compared with theoretical impedance respectly. By tuning the tunable screw coming through the top cover, we could improve sensitivity, signal-to-noise ratio, and spatial resolution to better than 1μm. To demonstrate the ability of local microwave characterization, the surface resistance of metallic thin films has been mapped.

        김승영,이배익,유관호 한국스포츠리서치 2003 한국 스포츠 리서치 Vol.14 No.4

        The present study was carried out to investigate the effects of physical training on glucose tolerance, insulin secretion, insulin sensitivity and insulin binding to erythrocytes in non-insulin dependent diabetic subjects(NIDDM) with fasting hyperglycemia and low insulin response during OGTT. The subjects were separated into two groups. One was diabetics treated with mild caloric restriction and physical training(Training group, n=18), the other was diabetics followed with mild caloric restriction alone(Sedentary group, n=20). Physical training consisted of 3-5 days weekly, 30 minutes sessions, with jogging corresponding to 40-50%VO₂max. Insulin sensitivity was determined by euglycemic insulin clamp technique. Following results were obtained. 1) Oral glucose tolerance was improved after 2 month training and remained unchanged thereafter in the training group. It was also improved in the sedentary group, however, the degree of the improvement in OGTT at 6 month treatment was more pronounced in the training group than in the sedentary group. 2) Amelioration of plasma insulin response during OGTT was observed after 6 months of treatment in the training group only. 3) After 2 months of treatment, glucose metabolic clearance rate(MCR) increased from 4.1㎖/㎏/min to 6.7㎖/㎏/min in the training group, but no change of MCR occurred in the sedentary group. 4) No significant changes in insulin binding to insulin receptors were observed in both the training and the sedentary groups. In conclusion, physical training improves glucose tolerance through an enhancement of insulin sensitivity and further insulin secretion in NIDDM with fasting hyperglycemia. It is useful as an adjunctive to diet in the treatment of NIDDM.

        실험적 뇌지주막하출혈 토끼에서의 Malonate 농도 측정

        김재중,하영수,백승렬,장정순,김유삼 대한신경외과학회 1995 Journal of Korean neurosurgical society Vol.24 No.10

        Malonate is regarded as a reversible competitive inhibitor of succinate dehydrogenase and malate transport in the Krebs cycle and showed neurotoxicity by persistent NMDA receptor activation due to inhibition of ATP production and glutamate utilization. However, little was known about its biological effects and the range of normal concentration of malonate in central nervous system. In order to understand the relationship between malonate and vasospsasm, malonate concentrations in rabbit model of experimental subarachnoid hemorrhage were measured at 0, 4th, and 7th day following SAH in serum, cerebrospinal fluid, and urine using malonyl-CoA synthetase. The results were as follows : 1) Malonate level is increased significantly in serum at the 4th day after subarachnoid hemorrhage that followed by vasospasm(p<0.01). 2) CSF malonate concentration tends to increase at post-SAH 7th day but statistically not significant. 3) The change of urine malonate concentration is not significant. These results suggest that early increase of serum malonate level is significant because clinically important vasospam begin from the fourth through the seven day after hemorrhage. The increased level of serum malonate at this time is due to impairment of cellular metabolism following delayed cerebral ischemia and may influence to development of vasospasm. In conclusion, the measurement of serum malonate concentration after subarachnoid hemorrhage is one of possible candidates for the early diagnosis of vasospasm.

        김지애,류승희,유성란,이준헌,서길웅,김선균,상병찬 충남대학교 농업과학연구소 2002 농업과학연구 Vol.29 No.2

        본 연구는 한국 재래 산양 112두와 유산양인 Saanen종 7두의 혈액으로부터 genomic DNA를 추출하고, PCR-RFLP 방법에 의해 β-casein 유전자의 특성을 분석하여 한국재래산양의 효율적인 유전자원의 보전 및 개량을 위한 기초 자료로 제공하고자 실시하였다. 한국재래산양의 genomic DNA로부터 PCR기법을 이용하여 β-casein의 유전자좌를 증폭한 결과 각각 481bp 크기의 단편이 양호하게 증폭되었음을 확인하였다. β-casein 유전자좌의 증폭산물에 대한 Bal Ⅰ의 제한효소를 처리한 결과, β-casein AB형은 481bp, 284bp 및 197bp의 단편을, 그리고 BB형은 284BP와 197BP의 단편을 한국재래산양과 유산양인 Saanen 종에서 확인 할 수 있었다, 유전자형 빈도에 있어서는 한국재래산양에서 β-casein AB 및 BB의 빈도는 각각 6.25 및 93.75%이었고, 유산양인 Saanen 종은 각각 57.14 및 42.86%이었다. 유전자빈도에 있어서는 한국재래산양의 β-casein A 및 B의 빈도가 각각 0.031 및 0.969이었고, Saanen 종에서는 각각 0.286 및 0.714의 빈도를 보였다 한국재래산양의 β-casein 유전자의 염기서열과 이미 보고되어 있는 goat의 염기서열(GeneBank accession Number M90556)간에는 총 11개의 염기서열에 차이를 나타내어 97.71%의 상동성을 보였다, 따라서 한국재래산양의 β-casein 유전자의 다형성과 염기서열 분석에 의한 분자유전학적 특성의 규명은 한국재래산양의 유전자원의 보전 및 개량을 위한 기초 및 응용 자료로 이용될 수 있을 것으로 생각된다. This study was performed to provide the basic data for preservation and improvement of genetic resources according to finding genetic construction obtained from analysis of genetic characteristics of β-casein gene in Korean Native goat and Saanen using the PCR-RFLP. This study confirmed the amplified products of 481bp fragments obtained from the amplification of β-casein loci by PCR. The β-casein AB genotype showed 481, 284 and 197bp, and β-casein BB genotype showed 284 and 197bp fragments in Korean Native goat and Saanen. The frequencies of β-casein genotype in Korean Native goat were 6.25 and 93.75% for AA and AB and the frequencies of β-casein genotype in Saanen were 57.14 and 42.86% for AA and AB types. The frequencies of β-casein A and B alleles were 0.031 and 0.969 in Korean Native goat and the frequencies of β-casein A and B alleles are 0.286 and 0.714 in Saanen, respectively. The nucleotide sequence of β-casein gene of Korean Native goat was 97.71% higher homology with 11 nucleotide sequences difference of that of goat reported in GeneBank (M90556). Therefore, this study of molecular genetic characteristics by the analysis of genetic polymorphism and sequencing for β-casein gene should be used as basic and applying data for preservation and improvement of genetic resources in Korean Native goat breeding.
