  • In patients with microscopic hematuria there is a need for better identification of those who are at greater risk of harbouring bladder tumors. The RisikoCheck(C) questionnaire has a strong correlation with the presence of urothelial carcinoma (UC) of the bladder and in combination with other available tests may help identify patients who require detailed clinical investigations due to increased risk of presence of bladder tumors. This study aimed to evaluate the efficacy of RisikoCheck(C) questionnaire together with NMP-22(R) (BladderChek(R)) as a point-of-care urine test in predicting the presence of bladder tumors in patients presenting with microscopic hematuria as the sole finding. In this multi-institutional prospective evaluation of 303 consecutive patients without a history of urothelial carcinoma (UC), RisikoCheck(C) risk group assessment, urinary tract imaging and cystourethroscopy as well as urine cytology and Nuclear Matrix Protein-22 (NMP-22 BladderChek) testing were performed where available. The sensitivity, specificity, negative predictive value (NPV), and positive predictive values (PPV) for the risk adapted approach were calculated. All patients underwent cystoscopy, and tumors were detected in 18 (5.9%). Urine cytology and NMP-22 was positive for malignancy in 9 (3.2%) and 12 (7.5%) of patients, respectively. A total of 43 (14%) patients were in the high risk group according to the RisikoCheck(C) questionnaire. The sensitivity and specificity of the questionnaire in detecting a bladder tumor was 61.5 % and 84.0 % in the high risk group. In patients with either a positive NMP-22 test or high risk category RisikoCheck(C), 23.6% had bladder tumors with a corresponding sensitivity of 54.2% and specificity of 88.6%. If both tests were negative only 3.3% of the patients had bladder tumors. The results of our study suggest that the efficacy of diagnostic evaluation of patients with microscopic hematuria may be further enhanced by combining RisikoCheck(C) questionnaire with NMP-22.

  • This paper presents a simple and reliable one-touch type multi-immunosensing lab-on-a-chip (LOC) detecting antibodies as multi-disease markers using electrochemical method suitable for a portable point-of-care system (POCS). The multi-stacked LOC consists of a PDMS space layer for liquids loading, a PDMS valve layer with 50 im in height for the membrane, a PDMS channel layer for the fluid paths, and a glass layer for multi electrodes. For the disposable immunoassay which needs sequential flow control of sample and buffer liquids according to the designed strategies, reliable and easy-controlled on-chip operation mechanisms without any electric power are necessary. The driving forces of sequential liquids transfer are the capillary attraction force and the pneumatic pressure generated by air bladder push. These passive fluid transport mechanisms are suitable for single-use LOC module. Prior to the application of detection of the antibody as a disease marker, the model experiments were performed with anti-DNP antibody and anti-biotin antibody as target analytes. The flow test results demonstrate that we can control the fluid flow easily by using the capillary stop valve and the PDMS check valves. By the model tests, we confirmed that the proposed LOC is easily applicable to the bioanalytic immunosensors using bioelectrocatalysis.

  • Currently commercially available phantom can reproduce and evaluate only a static situation, the study is incomplete research on phantom and system which is can confirmed functional situation in the kidney by time through dynamic phantom and blood flow velocity, various difference according to the amount of radioactive. Therefore, through this study, it has produced the dynamic kidney phantom to reproduce images through the dynamic flow of the kidney, it desires to evaluate the usefulness of nuclear medicine imaging. The production of the kidney phantom was fabricated based on the normal adult kidney, in order to reproduce the dynamic situation based on the fabricated kidney phantom, in this study it was applied the volume pump that can adjust the speed of blood flow, so it can be integrated continuously radioactive isotopes in the kidney by using 99mTc-pertechnate. Used the radioactive isotope was supplied through the two pump. It was confirmed the changes according to the infusion rate, radioactive isotopes and the different injection speeds on the left and right, analysis of the acquired images was done by drawn five times ROI in order to check the reproducibility of each on the front and rear of the kidney and bladder. Depending on the speed of injection, radioisotope was a lot of integrated and emissions up when adjusting the pressure of the pump as 30 stroke, it was the least integrated and emissions up when adjusting as 40 stroke. The integration of the left & right kidney was not reached in the amount of the highest when adjusting as 10 stroke. In the changes according to the amount of the radioactive isotope, 0.6 mCi(22.2 MBq), 0.8 mCi (29.6 MBq)was showed up similar tendency but, in the result of the injection 0.8 mCi, it was showed up counts close to double of 0.6 mCi. In the result of the differently injection speed of the left & right kidney, as a result of different conditions that injection speed was 20 stroke through left kidney phantom, the injection speed was 30 stroke through right kidney phantom, it was enough difference in the resulting image can be easily distinguished with the naked eye. Through this study, the results showed that the dynamic kidney phantom system is able to similarly reproduce renogram in the actual clinical. Especially, the depicted over time for the flow to be excreted through the kidney into the bladder was adequately reproduce, it is expected to be utilized as basic data to check the quality of the dynamic images. In addition, it is considered to help in the field of functional imaging and quality control.

  • 핵의학 검사 중 동적 신장검사는 신장기능을 평가하는 가장 대표적인 검사법으로 방사성동위원소를 이용하여 시간에 따른 신장의 기능을 평가하고 소변이 배설에 이르기까지의 질환 평가에 유용하다. 이러한 검사영상의 질 평가 및 정량 분석에서 현재 상용화 된 팬텀은 정적 상황만 재현하고 평가할 수 있기 때문에 동적 팬텀을 통한 시간에 따른 신장의 기능적 상황과 혈류속도, 방사성동위원소의 주입량에 따른 다양한 차이 등을 확인할 수 있는 연구가 미비한 상황이다. 그러므로 본 연구를 통해 동적 신장팬텀 시스템을 제작하여 신장의 동적 흐름을 통한 영상을 재현함으로써 핵의학에서 영상학적으로 유용성을 평가하고자 한다. 신장팬텀은 정상 성인 신장을 기준으로 제작하였고, 동적 상황을 재현하기 위하여 혈류의 속도를 조절할 수 있는 정량 펌프를 적용하였으며, $^{99m}Tc-pertechnate$를 신장팬텀에 방사성의약품이 집적되고 방광으로 배설되도록 제작하였다. 사용된 방사성의약품은 각 신장팬텀에 각각 주입되도록 하였으며, 주입속도, 방사성의약품, 좌우 신장팬텀에 다른 주입속도에 따른 변화를 확인하였다. 획득한 영상의 분석은 전면상과 후면상 각각의 신장과 방광에 관심영역을 그려 분석하였으며, 재현성을 확인하기 위하여 각 10회씩 반복하여 분석하였다. 동일한 조건하에 주입속도 40 mL/min로 고정하여 펌프의 압력을 조절하였을 때 방사성의약품이 2-3분 사이에 신장팬텀에 가장 많이 집적되었다가 방광으로 배출되었다. 각 장비별 사구체 여과율은 각각 SYMBIA 1,091 mL/min, FORTE 1,232 mL/min, ARGUS 1,264 mL/min, INFINIA 1,302 mL/min로 통계적으로 유의한 차이가 있는 것으로 나타났으며, Tmax 값 그리고 T1/2 값 모두에서 장비별 통계적으로 유의한 차이가 있는 것으로 나타났다. 변동계수인 CV 값은 5% 이하로 재현성이 있는 것으로 나타났으며, 그 중에서 SYMBIA가 2.67%로 가장 낮게 나타났고, INFINIA가 4.86%으로 가장 높게 나타났다. 본 연구를 통하여 동적신장팬텀시스템이 실제 임상의 신장동적검사를 유사하게 재현이 가능한 것을 확인할 수 있었다. 특히 신장을 통해 방광으로 배설되는 흐름에 대해 시간에 따른 묘사가 충분하게 재현되었으며, 동적 영상의 질을 확인하는데 기초 자료로 활용이 가능하리라 사료된다. 또한 추후 기능적 영상 분야에 연구 및 정도관리 분야에도 도움이 되리라 여겨진다.

  • 전립선암의 방사선치료에서 토모테라피와 용적변조회전치료(volumetric modulated arc therapy, VMAT)의 치료계획에 따른 유용성 평가를 위해 흡수선량, 선량체적곡선(dose volume histogram, DVH), 치료효율성, MapCHECK2를 이용한 선량 검증 정확도 결과를 각각 비교 분석하였다. 대상으로는 2014년 7월부터 12월까지 H 대학병원 방사선종양학과에서 토모테라피 치료를 받은 전립선암 환자 중 12명을 무작위로 선택하였다. 흡수선량과 DVH를 분석한 결과 종양조직과 방광에서 두 방사선 치료계획이 근소한 차이를 나타냈지만 처방선량의 오차범위인 -5%에서+3%안에 포함됐고 정상조직 부작용 확률 권고치인 견딤선량 범위를 넘지 않았다. 치료시간은 2.5배 짧고 MU(monitor unit)도 10.3배 작아 VMAT가 치료효율성이 높았다. 선량정확도는 모두 95% 이상의 통과기준에 포함 되었으며 VMAT가 2.3% 더 높게 나타났다. 토모테라피와 VMAT 모두 종양조직에 적합한 선량이 흡수되었으며 정상조직의 견딤선량 범위를 넘지 않아 선량분포특성에서 큰 차이는 없었다. 하지만 치료시간이 짧고, total MU가 낮아 치료효율성이 좋고 선량 검증의 정확도 또한 우수한 VMAT를 선택하는 것이 치료에 더 유용할 것으로 사료된다.

  • The theory of liver by Jang suk-sun[張錫純] is that first, although liver exists at right side of body and spleen at left anatomically, function of liver presents at left side of body and function of spleen at right based on principle of 'interdependence between eum and yang' and 'join strength with elasticity', and in the relation between liver and spleen, if gi of spleen ascends, gi of liver also ascends, and if gi of stomach descents, gi of gall bladder also descents. So. care of spleen and stomach becomes main point in treating disease of liver. The meaning of 'the liver being in charge of the evaporation'[肝主氣化] is that first, it raises the primordial gi and forms the 'great g' for it's circulation of whole body. Second., it excretes the functional activity of gi and connects heart with kidney and guides the evaporation of the whole body by connecting innate nature with acquired nature. Third, 'the liver being in charge of the evaporation' is realized by the help of spleen and stomach. And he said that this functional activity of gi is one of distinctive features that distinguish Oriental medicine from Western medicine. He discoursed upon physiology of 'the liver being in charge of the evaporation' and 'the Body belonged to yin and the Use belonged to yang' after seeing an evil of abusing drugs that calm the liver and check hyperfunction of liver by contemporary doctors. And he established a treat of 'warming and recuperating the gi of liver' [溫補肝氣法] and used it for symptoms of 'deficiency of liver-gi'[肝氣虛], 'exhaution of liver-gi'[肝氣脫], and 'the liver-cold'[肝寒證].
