  • Contracture is defined as the lack of full passive range of motion resulting from pint, muscle or soft tissue limitationprolonged Pint immobilization will result in stress and stretch deprivation and gradual development of contracture. the tissue changes caused by immobilization may be categorized as cellular modeling, ground substance and collagen response, and tissue response. contracture can be divided into three categories according to the anatomical location of pathological changes :arthrogenic, myogenic, soft tissue contractures Therapeutic approach of contracture is thermal or cold agents application, stretch or restoration of length, traction, manipulation, mobilization positioning and restoration of function. The purpose of this article is to review current concepts of mechanical properties and synthesis of collagen tissue and the underlying pathomechanics as it relates to evaluation and treatment of contracture.

  • The main purpose of this article is to make a handy Deep Friction Massager by using DFM in based on Dr. Cyriax's manual medicine. Also this study's aimed to heal soft tissue lesions - low back pain, neck pain, tennis elbow, golfer's elbow, frozen shoulder, myofibrosis etc. - which has resolved adhesion scar tissue problem in soft tissue. The results of this study were as followings ; 1. Deep friction massager has a effect not only massage but also healing, because it is broken the physiologic bridge of scar tissue in soft tissue. 2. It is possible to reduce the fatigue and effort of therapists during the deep friction massage. 3. Deep friction massager is made of handy form, so it is very convenient of using and application to patients.

  • Previously, we used a rigid bronchoscope in removal of endotracheal granulation tissue and foreign body. But these method has poor visual field and difficulty in handling of the instruments, therefore there were restriction in removing the endotracheal granulation tissue and foreign body. Recently we underwent one case each of endotracheal granulation tissue and foreign body causing dyspnea and removed them by right angled forceps under visualization via nasal rigid endoscope inserted through the tracheal stoma. We suggest this method for removal of tracheal foreign body, granulation tissue and excision of tumorous condition in patients with tracheocutaneous fistula.

  • Three-dimension paraffin compensator was designed to construct the tissue equivalent compensator for irregular body contours and obiliques beam incidence. The ratio of compensator thickness to tissue deficit was depended on field size, depth and air gap because the scattered dose loss. The ratio of compensator-tissue was optimized 0.79, 0.73, 0.61 and 0.56 in 6MV x-rays as function of field size $4{\times}4$, $10{\times}10$, $20{\times}20$ and $30{\times}30cm^2$ respectively. in our study. Using this tissue equivalent compensator, it can be got 2% difference of dose at same mid-plane in phantom study.

  • The use of aortic valve homograft has been developed since 1962 when Ross and Barratt - Boyes independently replaced a diseased aortic valve with an orthotopically inserted homograft valve. And also surgical treatment of complex congenital cardiac malformations utilizing homograft extracardiac conduit has been tried with better result than any other prosthetic material. The present study was undertaken to clarify the safety tissue viability, sterility, after following our protocol of procurement of heart, dissection of aortic and pulmonic homograft, sterilization, cryopreservation, thawing and dilution, and transplantation on experimental animal, sheep. Tissue viability of valve and great artery was assessed by tissue culture. Sterility was evaluated by bacterial and fungal culture. The method used was proven no deleterious effect on the integrity of the valve. Tissue culture of valve tissue before, and after cryopreservation process resulted that active fibroblast growth was observed from homograft sterilized with antibiotics. And culture of the transplanted homograft from sacrificed animal showed active fibroblast growth. Pathologic examination of implanted valve tissue from sacrificed sheep showed mild calcification and minor change, but there were moderate and severe calcification of wall of great arteries.

  • The purpose of this study was to investigate the changes of bony and soft tissue by the growth Each 50 boys and girls was studied aged 7 through 9 years old. The results were as follows; 1. Thickness of soft tissue was increased by the growth and much more done in boys than in girls. 2. In the linear measurement of soft tissue change of A-A' was most remarkable. 3. Nose length was increased in both boys and girls. Remarkable change was observed in male aged 8 through 9 years old and in female aged 7 through 8 years old. 4. In the linear measurement of bony tissue change, S-Pg, Go-Me, S-A, and S-N were increased in sequence. 5. Point-A and Pg in bony tissue grow more downward direction than forward. 6. In the angular measurement, no significant change was observed.

  • Cartilage defects are common and painful conditions that affect people of all ages. Although many techniques have developed, none of the current available treatment options is satisfactory. Recent advances in biology and materials science have pushed tissue engineering to the forefront of new cartilage repair techniques. The purpose of this study is to determine effective regeneration method for tissue-engineered cartilage. A serum free medium was developed for cartilage tissue engineering. Chondrocyte passage number was found to influence greatly on cartilage tissue formation in vivo. Injectable, biodegradable polymer matrix was developed for chondrocyte transplantation through injection. Transplantation of chondrocytes mixed with the injectable matrices resulted in the cartilage formation in nude mice's subcutaneous sites and rabbit knees. This study may lead to the development of tissue-engineered cartilage appropriate for clinical applications.

  • A Study of Clinical Application of the Connective Tissue Massage General massage is termed kneading and rubbing. It will bring the effect of blood volume and cardiovascular reaction. Connective tissue massage is a diagnostic and treatment method. But the general massage has not diagnostic aspect. Connective tissue massage techniques are stimulating and stretching the LCT, mast cell, collagenous fiber, fascia, skin, muscle and nerve tissue. Diagnostic aspects of connective tissue massage are visible investigation, manual investigation, and stroking on the reflex zone. CTM do stroking with 3, 4th finger tips on the whole body for the treatment.

  • 주사 전자현미경상에서 Hypoxylon속 4종(H. archeri, H. bovei, H. fragiforme와 H. stygium)의 자낭자좌 조직 형태를 중점적으로 관찰하였다. 본 연구는 Hypoxylon속의 자낭자좌의 각 층의 조직상 형태를 가장 심도있게 연구하였으며, 이 자낭자좌들은 동결파쇄법에 의하여 종단 및 횡단 절단되었다. 여러 개의 균일 된 자낭자좌 조직의 형태가 속내의 종간에 각기 다르게 형성되었다. 자낭자좌 조직의 형태는 Hypoxylon속의 종 수준에서의 분리동정을 위한 주검색 표로서는 미흡하나 보조 검색 표로는 매우 유용하다.
