Objective : Osteoporosis is a disease of unbalanced bone metabolism that results in low bone mineral density with increased bone fragility and propensity for fractures. The increased rate of bone fracture due to osteoporosis places a significant burden on public health care expenditures. Therefore, numerous studies have been designed and performed to identify the drugs or health foods that can improve the bone quality or quantity. This study was designed to evaluate and analyze the therapeutic effects of rutin on histomorphometric values of the spine and femur in an osteoporotic mouse model induced by bilateral ovariectomy. Methods : Thirty female ICR mice (8 weeks old) underwent either a sham operation (only abdominal incision, sham group, n=10) or bilateral ovariectomy (n=20). The ovariectomized (OVX) animals were randomly divided into two groups : untreated OVX group (OVX-C, n=10), or rutin-administered group (OVX-R, n=10). The OVX-C group received weight-adjusted doses of saline vehicle and the OVX-R group received 50 mg/kg of rutin intraperitoneally, starting 1 day after surgery. At 4 and 8 weeks after surgery, serum estrogen, osteocalcin, alkaline phosphatase (ALP), and the telopeptide fragment of type I collagen C-terminus (CTX-1) were analyzed. Interleukin (IL)-1β, IL-6, IL-10, and tumor necrosis factor (TNF)-α were also analyzed. Bone histomorphometric parameters of the 4th lumbar vertebra and femur were determined by micro-computed tomography. Results : In OVX-C group, ALP, osteocalcin, CTX-1, IL-1β, IL-6, and TNF-α levels were significantly increased at 4 and 8 weeks compared to sham operation group. Rutin administration after OVX statistically significantly reduced ALP, CTX-1, IL-1β, IL-6, and TNF-α levels at 4 and 8 weeks. Rutin administration also improves bone histomorphometric parameters including trabecular bone volume fraction, trabecular thickness, and trabecular number. Trabecular separation was also decreased in OVX-R group compared to OVX-C group. Conclusion : The present study demonstrated that rutin has therapeutic effects on improving bone histomorphometric values in an OVX mouse model. The improvement in histomorphometric values may be associated with the reduction of osteoclastic activity via inhibition of IL-1β, IL-6, and TNF-α. In future studies, the mechanism for the effect of rutin on osteoporosis should be demonstrated more clearly to use rutin in human osteoporosis.

유방암 환자의 외과적 수술과 방사선 및 화학적 치료 전 후의 골밀도 수치를 비교함으로써 암 치료에 의한 골소실 문제의 심각성을 도출하여 고 위험군선별 및 골다공증예방을 위한 기초자료를 제공하고자 하였다. 2007년 3월부터 2013년 9월까지 유방암으로 진단을 받고 수술 및 치료를 받은 후 골밀도 검사를 시행한 환자 254명을 대상으로 하였다. 이중 폐경에 이르렀거나 자궁적출술을 받아 폐경된 84명을 제외한 171명을 최종 분석의 대상으로 하였다. 방사선흡수법에 의한 골밀도 영상(요추부위와 대퇴골부위)에서 치료 전 후 측정된 골밀도 수치를 분석하였다. 치료 전 후의 전체적인 골밀도 변화량과 치료유형별 변화량을 비교하였으며, 환자의 결혼 유무, 자녀수, 수유유무, 초경나이, 유방암 치료형태 등을 변수로 하여 세부적인 차이점 및 연관성을 분석하였다. 측정된 자료는 SPSS for Windows Program(Version 18.0)을 사용하여 통계 분석하였다. 요추에서는 치료 후 평균 7.1% 감소하였고, 대퇴골에서는 평균 3.1% 감소하였으며, 통계적으로 매우 유의한 차이를 보였다(p<.01). 또한 화학적 치료를 시행한 환자군의 대퇴골 부위에서 치료 및 수술 후 $0.067g/cm^2$의 상대적으로 큰 골밀도 수치의 감소량을 보였으며 통계적으로 유의하였다(p<.05). 그 외 결혼 유무, 자녀수, 수유 유무, 초경 나이 등에 따라서는 감소량의 차이가 있었지만 통계적 수준에서 유의성은 없었다. 폐경 전 유방암 환자의 치료 후 골밀도 수치 감소를 보임에 따라 감소량이 상대적으로 큰 환자를 고 위험군에 포함시켜야 할 것이며, 이를 토대로 적극적인 예방 정책이 필요하리라 사료된다.

Objective : Traumatic disc lesion is a lesion with tremendous controversies. The causal relationships of this lesion are not established along with pathogenesis, diagnostic criteria, methods of treatment and the outcome. However, a significant number of patients with back pain after a trauma underwent spinal operations under the diagnosis of traumatic disc lesions. Such an ill-directed operation eventually produce a person with an iatrogenic disability. We present two illustrative cases, and tried to make a preventive method. Methods : We examined the path from mild trauma after a road traffic accident into the iatrogenic disability in two illustrative cases, who requested disability assessment and medical appraisement. We evaluated the reason and background for such an unwanted outcome and tried to find a method to reduce or prevent it by a literature review. Results : These two patients were admitted to the hospital with the diagnosis of lumbar sprain after a road traffic accidents. They eventually underwent spinal surgery under another diagnosis such as traumatic disc herniation or internal disc disruption. They stayed at the hospital for more than six months and finally lost their jobs. They became the disabled at last. Although they complained back pain, they never insisted by themselves that their symptoms were due to the traumatic disc lesion. To prevent such an iatrogenic disability, the doctors should assist them to go-back to the workplace promptly instead of a reckless extension of the treatment period. It may be necessary to evaluate the certificates to extend the treatment period with an additional diagnosis by a medical expert. To reduce the unnecessary long-term admission, a new billing system such as a partial share for the high cost of the treatment by the patients may be needed. Conclusion : It is not the patient but the doctors, who has the responsibility to avoid the unnecessary operations. All treating doctors should try to reduce or prevent such an iatrogenic complication caused by ourselves before we are forced to do so.

중추신경계의 원발성 림프종은 비호지킨림프종의 드문 형태이다. 그중에서도 말총의 원발성 T세포 림프종은 극히 드물다. 이 증례 보고는 4개월 전부터 시작된 허리통증과 하지방사통을 주소로 내원한 56세 여성의 증례에 대한 것이다. 요추 MRI에서 10 cm 크기의 길다란 다결절의 경막 내 병변이 4번 요추에서부터 2번 미추까지 있었으며 T1 강조영상에서는 등신호강도이고 T2 강조영상에서는 비균질적인 등신호강도와 고신호강도, 가돌리늄 조영증강 T1 강조영상에서는 비균질적인 강한 조영증강을 보였다. 말총 종괴에 대한 수술적 경막 내 생검을 시행하였고 면역조직화학염색과 T-cell receptor gamma 유전자 재배열 분석을 통한 진단은 말총의 말초 T세포 림프종이었다.
