The development of reliable methods to diagnose acute kidney injury is essential to allow the adoption of early therapeutic interventions and evaluate their effectiveness. Based on the fact that kidney injury molecule-1 (KIM-1) expression levels in kidneys are markedly upregulated early after a damage event, here we developed a noninvasive KIM- 1-based molecular imaging technique to detect kidney injury. First, we took advantage of a phage-display platform to select small peptides demonstrating a specific high binding affinity to KIM-1. The promising candidate was conjugated with fluorescent probes, and its imaging potential was validated in vitro and in vivo. This peptide, with the sequence CNRRRA, not only showed a high imaging potential in vitro, allowing a strong detection of KIM-1 expressing cells by microscopy and flow cytometry but also generated a strong kidney-specific signal in live-imaging in vivo experiments in the context of a drug-induced kidney-injury mouse model. Our data overall suggest that the CNRRRA peptide is a promising probe to use in the context of in vivo imaging for the detection of KIM-1 overexpression in damaged kidneys.

We described three cases of immediate reimplantation of a frozen-thawed autogenous mandible composed of a mixture of iliac bone, marrow, and particulate hydroxyapatite in tumors of the mandible. Acceptable outcomes were obtained in three patients who underwent immediate autogenous mandibular graft reconstruction. The conditions leading to successful outcome of the procedure are also discussed. Reimplantation of frozen autogenous lesioned mandible was performed in three patients with mandibular tumors. Two reimplanted grafts survived without complications following surgery. One case had postoperative infection that resolved with appropriate antibiotic treatment. There were no recurrences of the primary lesions. Satisfactory facial contour after surgery was achieved. These results are most promising, and we believe that, with further refinement, this technique will offer a new and acceptable modality for facial reconstruction in patients with cancer.

연구목적: 현재 우리나라의 의료분야에서는 정보기술의 발전으로 처방 전달 시스템과 전자차트의 활용이 상용화 되고 있으나 병원내에서 가장 많이 처방되고 검사되는 12-유도 심전도의 디지털화와 이에 연계된 심전도 결과의 개인용 컴퓨터로의 저장, 인터넷을 이용한 병원으로의 전송이나 타 기관에서의 심전도 결과의 동시 관찰 등에 관한 기술 등은 개발되지 못한 상태이다. 이에 본 연구에서는 심전도를 디지털화하며 저장이 가능한 PC 모듈을 개발하고 심전도 결과를 병원 전산 시스템에 포함시켜 병원내외에서 편리하게 조회, 검색할 수 있는 디지털 인터페이스를 개발하려 하였다. 재료 및 방법 : 낮은 전력에서 잡음특성이 우수한 대역여파기와 증폭기를 설계하였으며 각종기능이 내장된 고신뢰성 프로세서를 채택하였으며 전원 잡음이 고려된 필터와 전원 회로 설계로 하드웨어를 개발하였다. MSC 6.0과 Visual Basic 6.0을 바탕으로 하여 active X 모듈화를 유도하고 조회용 PC에서의 복원과 PACS로의 연동을 통해 순환기내과용 PACS 개발이 가능하도록 소프트웨어를 준비하였다. 결과: 심전도 검사자가 쉽게 장착, 검사가 가능한 소형화된 측정 모듈을 개발하였고 극저전류에서 동작이 가능하였으며 우수한 데이터의 압축 및 복원률을 구현하였다. 결론: 이번 심전도 디지털 모듈의 개발로 기존의 감광지에 의존하던 심전도 결과의 보존과 보관공간에 의한 경제적인 손실을 상당 부분 해결할 수 있으며 OCS에 연계된 결과로 인해 원내에서의 다면적 진료가 가능하다. 이번 연구에서 개발된 기술은 향후 디지털화된 심전도 기록장치와 같은 고부가 의료장치의 국산화와 광파일 의무기록 시스템이나 검사물의 무선 전송에 채용되어 의료 전달 체계나 응급체계의 발전에 기여하리라 사료된다. Purpose : The progressed communication technology commercialized the order communication system ( OCS) and the electric medical records( EMR) in the field of medicine in Korea. However, technologies of digitalization such as recording to personal computer, transfer to internet and simultaneous observation of electrocardiogram ( ECG) recorded at the different center were not realized yet. This study tried to invent personal computer module that can digitalize and record of the ECG and design the digital interface that can approach and search digitalized ECG in various part of hospital simultaneously. Materials and Methods : We had designed high-fidelity digital filter and amplifier which can work in very low voltage, had selected multifunctioned microprocessor. Activation X modulation was conducted by MSC 6.0 and Visual Basic 6.0. Softwares were prepared for the transfer of ECG informations from terminal PC to PACS and cardiologic PACS was designed for future application. Results : We have developed the small, portable, very low voltage managed ECG module and high quality digitalized information compression software in OCS and PACS. Conclusion : This invented ECG digital archive module can save hospital cost by substitution of ECG papers for digital storage or on-line storage, therefore ECG data can be handled in multisector of the hospital and through telemedicine. This technology can be applied to domestic ECG digitalizing device development and effective medical transfer system by adoption cordless medical information delivery.

목적 : 본 연구는 수근관 증후군의 발생위험이 높은 작업형태에 종사하는 상지 단순반복작업근로자로서 육류 및 어류 가공 사업장과 목재소 근로자에서 근전도검사를 이용하여 수근관 증후군의 유병률을 조사하고자 하였다. 방법 : 상지 단순반복작업근로자로서 육류 및 어류 가공 사업장 근로자 69명과 목재소 근로자 17명을 실험군으로, 관리직, 경리, 경비등 상지의 단순반복작업이 없는 근로자 28명을 대조군으로 선정하여, 작업적 및 병력조사, 이학적 검사와 근전도검사를 통해 수근관 증후군의 유병률을 조사하였다. 결과 : 수근관 증후군의 유병률은 육류 및 어류 가공 사업장과 목재소에서 각각 26.09 % (18명)와 29.41 %(5명)로 조사되었으며, 육류 및 어류가공사업장과 목재소 근로자를 '7년 이상과 미만의 작업기간'으로 층화하여 비교한 결과 '상지부위의 통증 호소 유무', 'Visual Analogue Scale(VAS: 총 10점) 4점 이상 여부', 'Tinel teat 양성 유무', 'Phalen test 양성 유무'는 모두 단기 작업근로자군에서 양성의 빈도가 증가되었고 '수근관 증후군 유무'는 장기작업근로자군에서 양성의 빈도가 증가되었다. 결론 : 육류 및 어류 가공 사업장과 목재소의 수근관 증후군 유병률은 각각 26.09 %와 29.41 %로 육류 및 어류 가공 사업장과 목재소는 1996년 OSHA가 지정한 바와 같이 위험한 작업요인이 있는 작업장으로 분류하여 관리되어야 할 것으로 생각된다. Objectives : This study was carried out to survey on the prevalence of Carpal Tunnel Syndrome(CTS) in high risk jobs(meat and fish processing plant and wood plant), by application of Nerve Conduction Study(NCS), a confirmatory diagnostic method. Methods : Experimental group was 69 workers sampled from meat and fish processing plants and 17 workers sampled from wood plants, who were simple, repetitive workers using upper extremities and control group was 28 workers sampled from managers, secretaries and keepers. All employees were examined through work history, physical examination and NCS. Results : 18 workers(26.09%) in meat and fish processing plants, and 5 workers(29.41%) in wood plants had compatible findings to NIOSH diagnostic criteria for CTS. The experimental group had more symptoms (complaint of upper extremities, Visual Analogue Scale ≥4(VAS: total 10 point)), signs(Tinel and Phalen test) and prevalence of CTS than control group(p<0.05). The prevalence of symptoms and signs were higher in short term workers(<7 years), but the prevalence of CTS was higher in long term workers(≥7 years). Conclusions : The prevalence of CTS in meat and fish processing plant and wood plant were 26.09% and 29.41% respectively. Authors propose that meat and fish processing and wood plants should be managed as a risk job category which were designated by OSHA in 1996

Aging is on the same line of birth, growth and death. So we analysed IGF-I promoter DNA profiles and sequences of normal short stature (NSS) patients for the purpose of comprehension of aging. We tested 52 NSS patients with DNA sampling. First we screened NSS DNAs with PCR (polymerase chain reaction) - SSCP (single strand confirmational polymorphism) method. We found only 1 patient out of 52 had abnormal SSCP band. Then we moved to subcloning of this PCR product into _(p)T7blue T-vector. We sequenced this DNA using antisense specific primer and 35S-dATP. Finally we confirmed two point mutations at the position of +8 and +74 from transcription initiation site. Next step for this study, we planned to transfection study for promoter function and gel retardation assay for new transcription factors.
