목 적: Hypopharynx Cancer의 VMAT 치료 시 Neck 부분에 Commercial Bolus(이하 CB)와 3D Printing 기술로 제작한 3D Bolus를 각각 적용한 두 치료 계획을 비교함으로써 3D Bolus 적용의 선량학적 유용성, setup 재현성 및 효율성을 알아보고 임상적 적용 가능성을 평가하고자 한다. 대상 및 방법: CB를 적용한 RANDO phantom의 CT image를 바탕으로 3D Bolus를 동일한 형태로 제작하였다. 3D Bolus는 OMG SLA 660 Printer, MaterialiseMagics software를 이용하여 SLA기법을 통해 밀도 1.2 g/㎤의 폴리우레탄 아크릴레이트 수지로 출력하였다. CB와 3D Bolus를 적용한 두 CT image를 바탕으로 Hypopharynx Cancer의 VMAT 치료를 가정하여 치료 계획을 수립하였다. 수립한 두 치료 계획을 각각 18회에 걸쳐 CBCT image를 획득하였고, 매 회 setup time을 측정하여 치료 효율성을 평가하였다. 획득한 CBCT image를 바탕으로 전산화 치료계획 시스템 Pinnacle을 통해 Adaptive Plan을 진행함으로써 Target, 정상 장기 선량 평가와 Bolus Volume의 변화를 평가하였다. 결 과: 각 치료 계획에 대한 setup time은 CB 적용 치료 계획에 비해 3D Bolus 적용 치료 계획에서 평균 28 sec 감소하였다. 치료 전 기간 내 Bolus Volume 변화는 CB Initial Plan 83.9㎤에서 86.1±2.70㎤, 3D Bolus Initial Plan 92.2㎤에서 99.8±0.46㎤로 나타났다. CTV Min Value의 변화는 CB Initial Plan 191.6cGy에서 167.4±19.38cGy, 3D Bolus Initial Plan 167.3cGy에서 149.5±18.27cGy로 나타났다. CTV Mean Value의 변화는 CB Initial Plan 227.1cGy에서 228.3±0.38cGy, 3D Bolus Initial Plan 225.9cGy에서 227.7±0.30cGy로 나타났다. PTV Min Value의 변화는 CB Initial Plan 128.5cGy에서 74.9±19.47cGy, 3D Bolus Initial Plan 139.9cGy에서 83.2±12.92cGy로 나타났다. PTV Mean Value의 변화는 CB Initial Plan 225.4cGy에서 226.2±0.83cGy, 3D Bolus Initial Plan 224.1cGy에서 225.8±0.33cGy로 나타났다. 정상 장기 Spinal Cord에 대한 Max Value는 매 회 평균 135.6cGy로 동일하게 나타났다. 결 론: 본 논문의 실험 결과를 통해 불균등한 체표면에 대한 3D Bolus의 적용이 Commercial Bolus 적용에 비해 선량학적으로 유용하고 setup 재현성 및 효율성 또한 우수함을 알 수 있었다. 추후 3D Printing 재료의 다양성에 대한 연구와 함께 추가적인 사례 연구가 진행된다면 방사선 치료 분야에서 3D Bolus의 적용이 더욱 활발하게 진행될 것으로 사료된다. Purpose: To find out the dosimetric usefulness, setup reproducibility and efficiency of applying 3D Bolus by comparing two treatment plans in which Commercial Bolus and 3D Bolus produced by 3D Printing Technology were applied to the neck during VMAT treatment of Hypopahrynx Cancer to evaluate the clinical applicability. Materials and Methods: Based on the CT image of the RANDO phantom to which CB was applied, 3D Bolus were fabricated in the same form. 3D Bolus was printed with a polyurethane acrylate resin with a density of 1.2g/㎤ through the SLA technique using OMG SLA 660 Printer and MaterializeMagics software. Based on two CT images using CB and 3D Bolus, a treatment plan was established assuming VMAT treatment of Hypopharynx Cancer. CBCT images were obtained for each of the two established treatment plans 18 times, and the treatment efficiency was evaluated by measuring the setup time each time. Based on the obtained CBCT image, the adaptive plan was performed through Pinnacle, a computerized treatment planning system, to evaluate target, normal organ dose evaluation, and changes in bolus volume. Results: The setup time for each treatment plan was reduced by an average of 28 sec in the 3D Bolus treatment plan compared to the CB treatment plan. The Bolus Volume change during the pretreatment period was 86.1±2.70㎤ in 83.9㎤ of CB Initial Plan and 99.8±0.46㎤ in 92.2㎤ of 3D Bolus Initial Plan. The change in CTV Min Value was 167.4±19.38cGy in CB Initial Plan 191.6cGy and 149.5±18.27cGy in 3D Bolus Initial Plan 167.3cGy. The change in CTV Mean Value was 228.3±0.38cGy in CB Initial Plan 227.1cGy and 227.7±0.30cGy in 3D Bolus Initial Plan 225.9cGy. The change in PTV Min Value was 74.9±19.47cGy in CB Initial Plan 128.5cGy and 83.2±12.92cGy in 3D Bolus Initial Plan 139.9cGy. The change in PTV Mean Value was 226.2±0.83cGy in CB Initial Plan 225.4cGy and 225.8±0.33cGy in 3D Bolus Initial Plan 224.1cGy. The maximum value for the normal organ spinal cord was the same as 135.6cGy on average each time. Conclusion: From the experimental results of this paper, it was found that the application of 3D Bolus to the irregular body surface is more dosimetrically useful than the application of Commercial Bolus, and the setup reproducibility and efficiency are excellent. If further case studies along with research on the diversity of 3D printing materials are conducted in the future, the application of 3D Bolus in the field of radiation therapy is expected to proceed more actively.

골대사에서의 마이오카인 아이리신 역할

Several studies have recently demonstrated that skeletal muscle is an endocrine organ releasing and expressing myokines acting in an endocrine or paracrine manner. Irisin is a hormene-like myokine induced after physical exercise by muscle fibers. It was primarily recognized as a molecule able to advance the “browning response” in white adipose tissue, however, it has been recetly identified that irisin also has a fundamental role in the control of bone mass. We study evidence for its possible skeletal effects, including the fundamental role that irisin is involved in the control of bone mass, with beneficial effects on geometry and cortical mineral density. As loss of muscle mass and bone density occurs with immobility, metabolic disease and aging, future studies researching the efficacy of irisin in reversing muscle wasting and restoring bone would be important to proving irisin as a molecule that combines helpful effects for treating muscular atrophy and osteoporosis in elderly people.

Purpose: The purpose of this study is to analyze the relationship between each Isokinetic muscle strength, pitching velocity and long-toss according to the dynamic balance ability level of high school baseball players. Method: The subjects of this study were 54 high school baseball players in Seoul and Gyeonggi-do Province, chosen as high dynamic balance ability group (27 people) and low dynamic balance ability group (27 people) using Independent t-tests and The Pearson Rank Correlation Coefficient to identify them. The Level of significance was set to α = 0.05. Results: The results of this study are as follows. All of the left and right muscle strengths except for the lumbar joint strength were similarly higher in the HB group than in the LB group. Pitching velocity and long-toss were also similarly faster and farther in the HB group. Also, the correlation between left and right dynamic balance ability and Isokinetic muscle strength for each lower body joint was significant in all joints except right extensor muscle & left flexor muscle. Long-toss also showed significant correlations in all variables except right pitching velocity. Conclusion: In summary, Dynamic balance ability is an essential element for effective energy transfer, and high muscle strength strengthening of lower body is considered to increase dynamic balance ability. Thus, if the Proprioception and balance training are applied to increase the muscle strength of the lower body, the pitching velocity will be improved.
