본 논문은 광역학적 암치료 효율을 높이기 위한 레이저 시스템의 최적화 구현에 관한 연구이다. 레이저 시스템의 최적화를 위해서는 레이저 출력의 출력 변동율과 파장대의 편이가 적어야 한다. 임상에서 암치료의 효율을 높이기 위해서는 악성종양부위에 조사되는 방사방식이 다양하게 구현되어야 한다. 기존에 사용되고 있는 C.W 방식은 정상조직에도 손상을 입힐 수 있는 생체조직의 열적효과를 가져올 수 있다. 이에 새로운 방사모드를 제안하여 생체조직에 대한 열적 안전성과 치료의 효율을 높였다. 실험을 통하여 광파장의 안정성 및 광 출력과 출력의 안정성을 확인 하였고, 피부조직의 열적 손상 방지를 위한 방사모드의 구현은 생체조직에 대한 실험을 통해서 본 연구의 타당성을 검증하였다.

Thoracic outlet syndrome's chief symptom has numbness and tingling sensation of tharm, hand and fingers. In the morning, patient complain of pins and needles of the hands and weakness. TOS classified three categories : Anterior scalene syndrome, Claviculocostal syndrome, Pectoralis minor syndrome Physical therapy of the TOS is heat, massage for soft tissue, stretching exercise for scalene muscles and pectoralis minor muscles, and strengthening exercise for upper trapezius and levator scapular and neck muscles. A main problem of soft tissue is mechanical causes, so physical therapists have to solve that problem by mechanical manual methods.

As one of the effective therapies for musculoskeletal diseases, orthopedic manual physical therapy has been watched with keen interest. In Korea, orthopedic manual physical therapy has been widely spread and applied in the field of clinical medicine since the mid-nineties. Since then, the clinical efficacy of orthopedic manual physical therapy has been approved, and orthopedic manual physical therapy has been gradually spread in the filed of clinical medicine. However, it should be noted that clinically available therapies are not well recognized. Therefore, this study was conducted to allude diagnostic and therapeutic characteristics of these therapies including deep tissue massage, manual therapy, Cyriaxs method combining manual reduction and chemotherapy, Kaltenborn-Evjenth method based on concave-convex rule for joint and soft tissue, Maitlands method based on patients sign and symptom, stress due to the posture, intraarticualr disturbance and Mckenzies method for pain due to the dysfunction.

This study was performed to investigate the effect of ultrasound irradiation on epidermal growth factor(EGF) expression in rat wound tissue. Skin wounds were created below 5mm to both sides of scapular inferior angle. The right wound was used experimental side and left was used control side. Ultrasound was irradiated pulse rate $20\%$, frequency 1MHz, intensity $0.5W/cm^2$ for 5 minutes during 3days. After sonication during 3 days, rats were sacrified. The expression of epidermal growth factor evaluated immunohistochemistry on mouse anti-EGF. In the control side, a little expression of EGF was observed at epidermis and dermis. In the experimental side, A strong immunostaining was seen at epidermis and dermis. This study suggests that ultrasound irradiation is effective on EGF expression in wound tissue.

Background: A pressure ulcer is common in soft tissue over the greater trochanter (GT) in side-lying position, and sustained tissue deformation induced by the prolonged external force is a primary cause, which can be discussed with soft tissues' viscoelastic properties (i.e., stress relaxation, creep response). Objects: Using an automated hand-held indentation device, we measured the viscoelastic properties of soft tissue over the hip area, in order to examine how the properties are affected by site with respect to the GT. Methods: Twenty participants (15 males and 5 females) who aged from 21 to 32 were participated. An automated hand-held indentation device was used to measure the stress relaxation time and creep response. Trials were acquired for three different locations with respect to the GT (i.e., right over the GT, 6 cm anterior or posterior to the GT). For each location, five trials were acquired and averaged for data analyses. Results: Soft tissues' stress relaxation time and creep response were associated with site (F = 23.98, p < 0.005; F = 24.09, p < 0.005; respectively). The stress relaxation time was greatest at posterior gluteal region (19.22 ± 2.49 ms), and followed by anterior region (15.39 ± 2.47 ms) and right over the GT (14.40 ± 3.18 ms). Similarly, creep response was greatest at posterior gluteal region (1.16 ± 0.14), and followed by anterior region (0.95 ± 0.14) and right over the GT (0.89 ± 0.18). Conclusion: Our results showed that the stress relaxation and creep were greatest at the posterior gluteal region and least at right over the GT, indicating that the gluteal soft tissue is more protective to the prolonged external force, when compared to the trochanteric soft tissue. The results suggest that a risk of pressure ulcer over the GT may decrease with slightly posteriorly rotated side-lying position.

Orthopaedic medicine was developed and published by James Cyriax, a British Orthopaedic Physician on 1929. Orthopaedic medicine is concerned with the diagnosis and treatment of soft tissue lesions. These disorders affect a substantial proportion of all patients in general and in particular, physiotherapy and sports clinics. In broad terms these disorders em trace conditions. such as arthritis. rheumatism. fibrositis. backache. lumbago, sciatica, frozen shoulder, tennis elbow, strained wrist, sprains, aches, inflanmation and sports injuries generally. The soft Moving tissues share one thing in common - they are all radiotranslucent and the tissues in question are the joint capsule, the ligaments, the fasciae, dural sheath. These structures can cause pain but none of them is visible on the radiograph. Dr. Cyriax divided all soft tissues into two basic types : 1) Contractile tissue, 2) Inert or noncontractile tissue. The mechanism of diagnosis is tension applied manually. The physician subjects each tissue about the incriminated joint to tension in turn which they call 'Selective tension' with Cyriax's assessment, a more definitive diagnosis can be obtained and proper treatment can be implemented.

Objectives: The purpose of this study was to evaluate the histopathological effects of an antioxidant therapy on the pulp tissue of rat teeth exposed to a bleaching gel with 35% hydrogen peroxide. Materials and Methods: Forty rats were subjected to oral ingestion by gavage of distilled water (DW) or ascorbic acid (AA) 90 min before the bleaching therapy. For the bleaching treatment, the agent was applied twice for 5 min each to buccal surfaces of the first right mandibular molars. Then, the animals were sacrificed at 6 hr, 24 hr, 3 day, or 7 day post-bleaching, and the teeth were processed for microscopic evaluation of the pulp tissue. Results: At 6 hr, the pulp tissue showed moderate inflammatory reactions in all teeth of both groups. In the DW and AA groups, 100% and 80% of teeth exhibited pulp tissue with significant necrosis and intense tissue disorganization, respectively. At 24 hr, the AA-treated group demonstrated a greater regenerative capability than the DW group, with less intense inflammatory reaction and new odontoblast layer formation in 60% of the teeth. For up to the 7 day period, the areas of pulpal necrosis were replaced by viable connective tissue, and the dentin was underlined by differentiated odontoblast-like cells in most teeth of both groups. Conclusions: A slight reduction in initial pulpal damage during post-bleaching was promoted by AA therapy. However, the pulp tissue of AA-treated animals featured faster regenerative potential over time.

Orthopedic medicine specializes in the diagnosis and treatment of musculoskeletal conditions. The physical therapy speciality, Orthopedic Manipulative Therapy(OMT) is an important part of orthopedic medicine. Much of OMT is devoted to the evaluation and treatment of joint and related soft tissue disorders and one of the primary treatment methods is mobilization. When examination reveals joint dysfunction, especially decreased range of motion, joint mobilization techniques are often utilized. Soft tissue mobilization techniques are used to improve mobility and other soft tissues. The therapist should have precautions for a patient. These precautions are based on the patient's concurrent medical and surgical diagnosis. Lastly, the literature describing therapeutic interventions in patients with musculoskeletal problem is poor because the painful conditions are poorly characterized and the therapeutic interventions are poorly described; so, where Kaltenborn-Evjenth concept for patient with musculoskeletal problem were identified, the treatment concept are introduced.
