Polyunsaturated fatty acids (PUFAs) are the major components of brain and retina, and are the essential fatty acids with important physiologically active functions. Thus, PUFAs should be provided to children, and are very important in the brain growth and development for fetuses, newborn infants, and children. Omega-3 fatty acids decrease coronary artery disease and improve blood flow. PUFAs have been known to have anti-inflammatory action and improved the chronic inflammation such as auto-immune diseases or degenerative neurologic diseases. PUFAs are used for metabolic syndrome related with obesity or diabetes. However, there are several considerations related with intake of PUFAs. Obsession with the intake of unsaturated fatty acids could bring about the shortage of essential fatty acids that are crucial for our body, weaken the immune system, and increase the risk of heart disease, arrhythmia, and stroke. In this review, we discuss types, physiologic mechanism of action of PUFAs, intake of PUFAs for children, recommended intake of PUFAs, and considerations for the intake of PUFAs.

The control of the chronic degenerative diseases becomes a challenge in Korea as the aging of the population progresses. Accordingly, the importance of the control of the hypertension, one of the major chronic degenerative diseases, in the primary health care settings increases. However, such control activities are still minimal. This study gives brief description of how the rural residents who are currently registered for the control of the hypertension feel about the activities of the health centers, subcenters and the CHP posts, in relation to the control of the hypertension. We also describe the knowledge and practice of the registered hypertensive. In general, the knowledge, the acceptance and the satisfaction of the respondents about the hypertension control activities were not very high. Respondents being managed by the health center showed the highest knowledge, acceptance and satisfaction, and those being managed by the subcenters ranked lowest. The knowledge about the hypertension was not satisfactory. There were great variations among the items in terms of the proportion answered correctly. As many as 60% of the respondents take medication regularly but only 4.5% were practicing weight control regularly. Despite some limitations of the study, the results can be very useful for those planning hypertension control programs. The educational materials and the dietary protocols need to be developed in accordance with the regional social and food pattern, so that they can be utilized with minimal modification for each beneficiary. We also suggest to minimize the area a health personnel covers. In other word, running several small health posts at village level would be more effective than running a subcenter at the township level, in terms of the hypertension control.

Objective : The purpose of this study was to determine the feasibility of screw fixation in previously augmented vertebrae with bone cement. We also investigated the influence of cement distribution pattern on the surgical technique. Methods : Fourteen patients who required screw fixation at the level of the previous percutaneous vertebroplasty or balloon kyphoplasty were enrolled in this study. The indications for screw fixation in the previously augmented vertebrae with bone cement included delayed complications, such as cement dislodgement, cement leakage with neurologic deficits, and various degenerative spinal diseases, such as spondylolisthesis or foraminal stenosis. Clinical outcomes, including pain scale scores, cement distribution pattern, and procedure-related complications were assessed. Results : Three patients underwent posterior screw fixation in previously cemented vertebrae due to cement dislodgement or progressive kyphosis. Three patients required posterior screw fixation for cement leakage or displacement of fracture fragments with neurologic deficits. Eight patients underwent posterior screw fixation due to various degenerative spinal diseases. It was possible to insert screws in the previously augmented vertebrae regardless of the cement distribution pattern; however, screw insertion was more difficult and changed directions in the patients with cemented vertebrae exhibiting a solid pattern rather than a trabecular pattern. All patients showed significant improvements in pain compared with the preoperative levels, and no patient experienced neurologic deterioration as seen at the final follow-up. Conclusion : For patients with vertebrae previously augmented with bone cement, posterior screw fixation is not a contraindication, but is a feasible option.

본원에서 방아쇠 수지 환자 3례를 자하거 약침으로 5-7회 치료한 결과 유의한 효과가 있었다. 그러나 연구자의 치료예가 부족하여 4도 정도로 굴건의 걸림이 심한 경우나, 양방의 보존적 치료 후 재발되는 경우, 증상이 오래된 경우에 대한 연구와 1년 후의 재발율에 대한 추적 조사가 더 필요한 것으로 생각된다. 그리고 방아쇠 수지를 급성기, 결절형의 염증상태와 만성기, 미만형 퇴행상태로 정확하게 구분하여 염증상태에는 봉약침을 사용하고, 퇴행화 상태에서는 자하거 약침을 사용한다면 좋은 효과를 볼 것으로 기대된다. 앞으로 각종 수지관절 및 건의 질환에 대한 치료방법에 대한 연구가 더욱 더 필요할 것으로 생각된다.

Objectives : In lumbar spine surgery it is observed that the ligamentum flavum(LF) is bilayered, and the inner layers can be left in situ to prevent peridural adhesion in open lumbar disc surgeries. The purposes of this study are to investigate ultrastructural differences between the inner and outer layer of lumbar LF by electron microscopic examination, and to see whether these differences are, if present, more prominent in chronic degenerative lumbar spinal disorders as compared with acute lumbar disc diseases. Methods : Biopsy specimens of LF were obtained from nine patients undergoing lumbar spine surgery, five of them for degenerative spinal stenosis and four for acute disc herniation. During the surgery the outer layers of LF were carefully dissected from the inner layer, and four pieces($1{\times}1{\times}1-mm$) of biopsy samples were made from each layer. These were examined with electron microscope for the morphologies and the contents of the elastic and the collagen fibers. Results : The outer layer of LF showed elastic fiber degeneration as evidenced and decreased fiber content, while the inner layer was relatively preserved in both cases of degenerative spinal stenosis and acute disc herniation. The ultrastructural changes of the layers were more evident in the outer layer. Conclusion : With these observations the authors believe that the LF degeneration may occur mainly in the outer layer, and that this fact may aid in making the rationale for using the inner layer as physiologic barrier to prevent peridural adhesion in open lumbar disc surgeries.

Objective : Spinal degeneration is a progressive disease, worsening over time. Lumbar degenerative disease (LDD) is a major spinal disease in elderly patients. Surgical treatment is considered for medically intractable patients with LDD and reoperation after primary surgery is not uncommon. The surgical outcome is occasionally unpredictable because of comorbidities. In the present study, the relationship between comorbidities and the incidence of reoperation for LDD over time was determined. Methods : The claims data of the health insurance national database were used to identify a cohort of patients who underwent spinal surgery for LDD in 2009. The patients were followed up until 2016. Medical comorbidity was assessed according to the Charlson comorbidity index (CCI). Cox proportional hazard regression modeling was used to identify significant differences in sex, surgery, age, causative disease, and comorbidity. Results : The study cohort included 78241 patients; 10328 patients (13.2%) underwent reoperation during the observation period. The reoperation rate was statistically higher (p<0.01) in males, patients 55-74 years and 65-74 years of age, and patients with decompression or discectomy. Significant association was found between increasing reoperation rate and CCI score (p<0.01). Based on multivariate analysis of comorbidities, the significantly higher reoperation rates were observed in patients with peripheral vascular disease, pulmonary lung disease, peptic ulcer, diabetes, and diabetes complications (p<0.01). Conclusion : The study results indicate the reoperation rate for LDD is associated with patient comorbidities. The comorbidities identified in this study could be helpful in future LDD studies.

골관절염은 관절의 연조직, 관절연골 및 연골하 골조직의 합성과 분해 사이의 불균형으로 인한 조직의 변성을 야기하는 관절의 질환이다. 일반적으로 골관절염은 연령에 따라 급격히 증가하고, 여성에서 호발하는 특징을 보이는 것으로 알려져 있지만, 측두하악관절에서의 골관절염의 유병률에 관한 연구는 측두하악관절의 독특한 특성에도 불구하고 정확한 연구가 부족한 실정이다. 본 연구에서는 측두하악관절에서 발생하는 골관절염의 실제 성별, 연령별 분포 및 임상적 특징을 알아봄으로 써 병인의 이해에 필요한 기초 자료를 제시하고자 한다. 본 연구에서는 2007년 1월부터 12월까지 1년 동안 서울대학교 치과병원에 측두하악장애를 주소로 처음 내원한 4327명의 환자를 대상으로 하였다. 측두하악장애의 진단을 위해 촬영된 orthopantomogram, TMJ tomogram, transcranial radiograph를 이용하여 측두하악관절의 퇴행성 변화를 조사하였으며, 성별, 연령, 골변화 양상에 따른 분포를 분석하여 다음과 같은 결과를 얻었다. 1. 측두하악장애 증상을 호소하는 환자 4327명 중 883명 (20.4%)에서 퇴행성 변화가 관찰되었고, 남성에서는 177명 (12.6%), 여성에서는 706명 (24.1%)에서 관찰되어 여자에서 호발하는 것으로 관찰되었으며, 이러한 여성 우위의 호발 양상은 모든 연령대에서 관찰되었다. 2. 측두하악장애 증상을 호소하는 환자 중 하악과두의 퇴행성 변화를 보이는 환자의 비율은 연령대가 증가함에 따라 완만하게 증가하였고, 연령별로 구분하여 볼 때에는 여성에서는 연령대별 발생비율의 증가가 통계적으로 유의하였으나 (P < 0.001), 남성에서는 통계적으로 유의하지 않았다. 3. 퇴행성 변화 환자군에서 나타나는 퇴행성 변화의 유형 중, 발생빈도가 가장 높은 형태는 sclerosis였고 (84.6%), 발생 환자 의 평균연령이 가장 높은 형태는 osteophyte였다 (44.8세). 4. 퇴행성 변화의 좌, 우 발생 분포를 보면 좌측에서 호발하였고, 남성 내에서는 좌측, 여성 내에서는 양측에서 모두 발생한 비율이 가장 높았으나, 전체적인 좌, 우 발생 양상은 남녀간에 통계적으로 유의한 차이를 보이지 않았다. 결론적으로, 측두하악장애 환자에서 나타나는 측두하악관절의 퇴행성 변화는 여성에서 호발하고 연령이 증가함에 따라 완만한 증가를 보이며 젊은 연령층의 환자에서도 높은 비율로 발생함을 알 수 있다. 측두하악장애가 젊은 연령층에서 호발한다는 이전의 보고들을 토대로 볼 때 측두하악관절의 퇴행성 변화는 타관절에서 발생하는 퇴행성 변화와는 다른 역학적 특징을 가지고 있을 가능성이 크며, 이러한 사실은 측두하악관절에서 발생하는 퇴행성 변화의 병인을 이해하고 그 치료법을 개발하는데 있어서 매우 중요한 의미를 가진다.

연구 계획: 후향적 방사선 연구 목적: 경추와 요추에 동시에 발생한 퇴행성 척추전위증을 알아보고자 한다. 선행 연구논문의 요약: 경추와 요추에 동시에 발생한 퇴행성 척추질환에 대한 여러 보고가 있었다. 퇴행성 척추전위증은 퇴행성 변화에 의하여 시발되므로 경추와 요추에 척추전위증이 병발할 것으로 추정된다. 반면에, 요추와 경추의 해부학적 구조가 서로 다르므로 두 질환의 진행이 동일하지 않을 것으로 추정할 수도 있다. 그러나, 경추와 요추에 동시에 발생한 퇴행성 척추전위증에 대한 보고는 적었다. 대상 및 방법: 요추 및 경추 부위에 기립위 단순방사선 검사를 둘다 시행한 퇴행성 척추 질환 환자 2,510명을 대상으로 하였다. 병발여부, 나이, 성별, 전위증의 방향에 대하여 조사하였다. 퇴행성 요추전위증은 기립위 단순방사선영상에서 Meyerding 방법을 사용하여 grade 1 이상인 경우 진단하였으며 퇴행성 경추전위증은 기립위 단순방사선영상에서 2 mm 이상의 전위가 보이는 경우 진단하였다. 결과: 퇴행성 요추전위증은 125명에서 관찰되었으며(5.0%) 퇴행성 경추전위증은 193명에서 관찰되었다(7.7%). 요추전위증과 경추전위증은 17명에서 같이 관찰되었다(0.7%). 요추전위증이 있는 환자가 없는 환자에 비하여 경추전위증이 더 많이 관찰되었다. 요추전위증은 남자보다 여자에서 더 흔하였으나, 모든 연령군에서 비슷하게 발생하였다. 경추전위증은 고령의 연령군에서 더 많이 발생하였으나, 남녀의 발생 비율이 비슷하였다. 요추전위증에서는 전방으로 많이 발생하였고, 경추전위증에서는 후방으로 많이 발생하였다. 결론: 퇴행성 요추전위증이 있는 경우가 없는 경우에 비하여 퇴행성 경추전위증이 더 많이 발생하였다.

Glutamate-induced oxidative stress results in neuro-degenerative disorders in many central nervous system (CNS) such as Alzheimer's disease, ischemia, Huntington's disease, and Parkinson's disease. Our study was performed to investigate neuroprotective effects of Allium hookeri extracts (leaf, root, and whole) on glutamate-induced HT22 cells. In this study, ethanol extract of A. hookeri showed the outstanding neuroprotective effect in HT22 cells. In addition, we found that ethanol extract of A. hookeri root increased heme oxygenase (HO)-1 in HT22 cells. Moreover, ethanol extract of A. hookeri root also upregulated nuclear accumulation of nuclear factor E2-related factor 2 (Nrf2) in HT22 cells. These results demonstrate that ethanol extract of A. hookeri root contributes neuroprotective effects against glutamate-induced oxidative stress in HT22 cells, via Nrf2-mediated HO-1 expression. Our study suggests that ethanol extract of A. hookeri root could be the potential agent for the treatment of many neuro-degenerative diseases.
