  • 본 연구에서 방광 내벽과 외벽사이의 거리를 측정하여 뇨량을 계산하는 시스템에 적용하기 위한 방광용 초음파 변환기를 설계하고 개발하였다. 뇨량 측정 시스템은 방광에서 오줌을 배출하기 전의 양을 측정함으로써 뇨실금 환자의 치료 과정을 도와주게 된다. 이 실험의 결과로, 뇨량을 더 정확하게 측정할 수 있고 또한 뇨실금 방지 시스템을 개발할 수 있다. 본 연구를 통하여 개발되는 시스템은 뇨실금과 야뇨증 환자를 더 오래 더 건강한 삶을 살 수 있도록 해줄 수 있을 것이다.

  • Objective : The using of termionology in medicine is important because terminology discriminates the meaning of words. In that aspect, there are conflicts that bao has plenty of meanings as medical terminology(womb and urinary bladder). Therefor, we need to discriminate and define bao. Method : We compare terminology of bao and words related with bao such as pao(胞) in "Dongeuibogam", "Hwangdineijing" and medical dictionary. Also we try to define right meaning of words as medical terminology. Result : Bao has several meanings in medical books. However, they have tendencies that could make scholars choose appropriate terminology in medicine. Conclusion : Bao is preferred as a womb and pao is prefferd as a urinary bladder in medical terminology.

  • 이 연구는 신경인성 방광 쥐 모델에서 줄기세포에 의해 발현된 뇌유래신경영양인자가 하부요로 증상에 미치는 영향을 조사하였다. 48마리의 Sprague-Dawley 쥐를 정상군, 하부요로증상군, 하부요로증상+imMSC군 및 하부요로증상+BDNF-eMSC군으로 무작위 선정하였다. 하부요로증상모델은 골반신경절 손상에 의해 유도되었으며 방광 기능평가는 마취 하에 실시하였고, 수축성 검사 및 웨스턴 블롯 분석을 위해 방광 조직을 절제하였다. 뇌유래신경영양인자 발현 중간엽줄기세포 치료가 하부요로증상에 미치는 영향도 평가되었으며 뇌유래신경영양인자 발현 중간엽줄기세포는 방광 조직의 섬유화를 억제하였고 Caspase-3 발현을 감소시켰다. 결론적으로, 뇌유래신경영양인자 발현 중간엽줄기세포는 하부요로증상 쥐 모델에서 세포 사멸의 억제와 함께 방광의 기능 및 수축성의 회복을 가져왔다.

  • Objective: To investigate whether apoptin is a apoptosis-inducing protein with a potential for bladder cancer therapy. Methods: We constructed a PCDNA3/Apoptin eukaryotic expression vector, and transfected this vector into bladder cancer cell lines BIU-87 and EJ, then observed the results by RT-PCR, transmission electron microscopy, MTT assay and the flow cytometry (TUNEL method). Results: PCDNA3/Apoptin successfully induced a high level apoptosis in both bladder cancer cell lines, compared with the controls (p<0.05). Conclusions: Apoptin can induce high level apoptosis in human bladder cancer EJ and BIU-87 cells, which suggests a potential for human bladder cancer therapy.

  • Patients with neurogenic bladder undergo morphometric and functional changes of their bladder and urethra. As a result, voiding symptoms such as frequency, nocturia, urgency and incontinence appear. We experienced two cases of the urinary incontinence treated with Samboo-tang(Sanfu-tang). In the point of Differentiation of Syndrome, two cases were diagnosed as Deficiency Syndrome of Yang of the kidneys. After Samboo-tang(Sanfu-tang) administration, the frequency of the urinary incontinence were decreased and the accompanied symptoms also improved. So, we report two cases with a brief view of related literatures.

  • A giant prostatic urethral calculus has not been previously reported in dogs and should be distinguished from prostatic calculus. A 7-year-old castrated male Maltese dog with a 2-month history of relapsing hematuria and urinary incontinence with slowly progressing paraphimosis was referred. On abdominal radiography and ultrasonography, there was a giant calculus in the region of prostate or urethra, one left ureteral calculus, one urinary bladder calculus, and two penile urethral calculi. On computed tomography for evaluating the accurate location and planning the surgical approach, the giant calculus was located at the prostatic urethra. The calculi in urinary bladder, prostatic and penile urethra were surgically removed. These calculi were mixed-type of calcium oxalate monohydrate, struvite and calcium phosphate carbonate. On the basis of the urolith analysis and urine bacterial culture results, antibiotics and prescription diet were adjusted. At the 3-month follow-up, there were no clinical sings but paraphimosis was still remained, and ultrasonography revealed newly-formed, small urethral calculi at the prostatic urethra. This is the first report to describe the case of a canine giant prostatic urethral calculus and its clinical signs, diagnostic imaging findings, treatment, and outcome. CT may be useful to assess the accurate location and surgical approach for such calculi.

  • Study Design: Retrospective case series. Purpose: Cauda equina syndrome (CES) is associated with etiologies such as lumbar disc herniation (LDH) and lumbar canal stenosis (LCS). CES has a prevalence of 2% among patients with LDH and exhibits variable outcomes, even with early surgery. Few studies have explored the factors influencing the prognosis in terms of bladder function. Therefore, we aimed to assess the factors contributing to bladder recovery and propose a simplified bladder recovery classification. Overview of Literature: Few reports have described the prognostic clinical factors for bladder recovery following CES. Moreover, limited data are available regarding a meaningful bladder recovery status classification useful in clinical settings. Methods: A single-center retrospective study was conducted (April 2012 to April 2015). Patients with CES secondary to LDH or LCS were included. The retrieved data were evaluated for variables such as demographics, symptom duration, neurological symptoms, bladder symptoms, and surgery duration. The variable bladder function outcome during discharge and at follow-up was recorded. All subjects were followed up for at least 2 years. A simplified bladder recovery classification was proposed. Statistical analyses were performed to study the correlation between patient variables and bladder function outcome. Results: Overall, 39 patients were included in the study. Majority of the subjects were males (79.8%) with an average age of 44.4 years. CES secondary to LDH was most commonly seen (89.7%). Perianal sensation (PAS) showed a significant correlation with neurological recovery. In the absence of PAS, bladder function did not recover. Voluntary anal contraction (VAC) was affected in all study subjects. Conclusions: Intactness of PAS was the only significant prognostic variable. Decreased or absent VAC was the most sensitive diagnostic marker of CES. We also proposed a simplified bladder recovery classification for recovery prognosis.

  • 국내외 학술지중 배뇨장애에 대한 침치료의 연구 동향을 문헌고찰 연구, 생리적 기전 연구, 임상효과 연구로 나누어 분석한 결과 다음과 같은 결과를 얻었다. 1. 23 편의 논문 중 review study가 3편, experimental study 6편, clinical study가 14 편이었다. 다양한 Journal에 발표되고 있었는데, review study는 모두 국내 학술지에 게재 된 논문이었고, 2000년 이후로 점차 연구의 양과 관심이 증대되고 있는 추세였다. 2. 배뇨장애는 하부요로증상의 다양한 증상을 포괄하는 것으로 한의학적인 측면에서는 융폐, 소편부금(小便不禁), 빈요(頻尿), 급박요(急迫尿), 요실금(尿失禁), 림증(淋證), 야뇨(夜尿), 난요(難尿), 점적요(點滴尿), 지연요(遲延尿)등에 해당하는데, 그 대부분의 유발 원인은 신기부족(腎氣不足)등의 하초허한(下焦虛寒)에 기인하는 것으로 판단되며, 간기울결(肝氣鬱結)등의 정서적 자극과 습열(濕熱) 및 어혈(瘀血)등의 원인에 의해서도 발생할 수 있다. 3. 배뇨장애에 대한 침구치료의 생리적 기전을 대략적으로 요약한다면 침자극에 의해 부교감 신경, 대뇌의 수면-각성 체계, 뇌교 및 척추 배뇨 센타, 음부신경/골반신경을 통해 방광에 영향을 주어 방광용량의 확장 또는 배뇨 수축의 억제작용을 하는 한편, 척추 환상 회로 나 신경연접부의 지속성 흥분을 통하여 요도주의 근육에 영향을 주는 것으로 생각되어 진다. 4. 배뇨장애에 대한 침구치료의 임상효과를 요약 한다면, 융폐, 소편부통(小便不通)에 속하는 신경인성 방광(Neurogenic Bladder), 소편부금(小便不禁), 빈요(頻尿), 급박뇨(急迫尿)에 해당하는 요실금(尿失禁)(Incontinence), 림증(淋證)에 해당하는 방광염(Cycitis), 액요(液尿) (Nocturnal Enuresis), 잡요(雜尿), 점적요(點滴尿), 지연요(遲延尿)에 해당하는 전립선염/골반통 증후군 (Prostatitis/Pelvic Pain Syndrom)등의 하부 요로증상에 침구치료는 유의미한 효과가 있다. 이상으로 국내 및 해외 연구는 최근들어 더욱 활발히 연구되고 있는데, 특히 해외연구는 배뇨 장애의 침구치료의 생리적 기전 분야에서 다양 하게 시도되고 있었다. 향후 고령화 사회로 진입 하는등 사회여건상 이와같은 다양한 배뇨장애 환자의 증가는 물론 치료욕구의 증대가 예상되는 바 이러한 생리적 치료기전의 연구 및 다양한 질환에 대한 임상연구를 시도함으로써 표준적인 치료기술의 개발이 필요할 것으로 사료된다.
