  • Free vascularized composite tissue transfer is more frequently underwent for reconstruction of complicated tissue defects with the recent advance of microsurgery. But postoperative result was not satifactory because of donor site morbidity, flap bulkiness and cosmetic problem. So would no longer be a problem if we can obtain the exact donor tissue required for the recipient site as allotransplantation and designing the flap. Allotransplantation has been resolved with the recent development of immunosuppressive agents, while reconstruction has made great progress with the refinement of microsurgical techniques in the last 20 years. The final sucess or failure of the operative procedure in transplantation is so utterly dependent no the availability of strategies that can control the immune system effectively, selectively, safely to allow allotransplantation of a nonvital body part. 1 used 2 strains of rats, BUF and LEW, for the limb allotransplantation as a composite tissue transfer. The primary goal of this program is to improve results in clinical transplantation by accelerating the transformation of new immunological knowledge into useful medicine. Two of the most promising new immunosuppressive compounds are FK-t06(FK) and rapamycin(RPM). Both drugs are antibiotic macrolide fungal fermentation products that presumably suppress the immune system in ways similar to cyclosporin(CyA). This study shows that two new immunosuppressive drugs compare the immunosuppressive activity and effectiveness of FK-506 and RPM for prevention of the limb allograft rejection in the rat. Additional experiments investigate the dose, route of administration and histologic findings. These data demonstrates that rapamycin is far more potent and effective than FK-506 when both compounds are administered by the intraperitoneal route, as well as prolonged graft survival significantly in a dose-route dependent manner. These results lead to the view that vascularized allograft composite tissue transfer can become a reality with the expectation of possible future application in reconstructive surgery of humans.

  • Background: The effect of mobilization on lumbar back pain has been fully described in several clinical aspects, but evidence for muscle strength would be still less clear. Objective: To assess the effect of lumbar mobilization on lower limb strength in healthy individuals. Methods and Analysis: Healthy people aged 18-65 will be included regardless of race or sex. Original peer-reviewed primary reporting randomized controlled trials (RCTs) will be included. Electronic databases, such as MEDLINE, EMBASE, Cochrane Central Register of Controlled Trials, Web of Science, Pedro, CINAHL, ClinicalTrials.gov will be searched from inception until July 30. Only studies published in English will be included in this review. Two reviewers will complete the screening for eligibility independently, and the other two reviewers will also complete the risks of data extraction and bias assessment independently. Lower Limb strength will be assessed as primary outcome, and particular intervention or participant characteristics will be assessed as the secondary outcomes. Meta-analysis will be conducted using Review Manager 5.3.3, and evidence level will be assessed using the method for Grading of Recommendations Assessment, Development and Evaluation. Outcomes will be presented as the weighted mean difference or standardized mean difference with 95% CI. If I2 ≤ 50%, P>.1, the fixed effect model will be used, otherwise, random-effects model will be used. Ethics and dissemination: This review might not be necessary ethical approval because it does not require individual patient's data; these findings will be published in conference presentations or peer-reviewed journal articles. PROSPERO registration number: CRD42020150144.

  • Objective: The purpose of this study is to compare EMG activity during horticulture motion and upper limb rehabilitation motion, to confirm whether horticulture motion is suitable for upper extremity rehabilitation of hemiparesis. Design: Three-group cross-sectional design. Methods: The 45 subjects were divided into three groups: hemiparesis (n=15), elderly (n=15) and healthy (n=15). We have recorded EMG signals of six upper limb muscles Upper trapezius (UT), Middle deltoid (MD), Anterior deltoid (AD), Biceps brachii (BB), Triceps brachii (TB), Brachioradialis (BR) during horticultural motions and three upper limb rehabilitative motions. The dependent variables were peak EMG, integral EMG, co-contraction ratio. A two-way repeated measures ANOVA was used to compare the horticultural motion and rehabilitation motion of the three groups. Results: The peak EMG was significantly different in MD, AD, BB, TB according to the motion(p<0.05), and the UT, BB were significant differences according to the group(p<0.05). The integral EMG was significantly different in MD, AD, BB, TB, BR according to the motion(p<0.05), and the BB were significant differences according to the group(p<0.05). The co-contraction ratio was significantly different in TB/BB according of the motion, and there was no difference between the groups. Conclusions: As a result of this study, horticultural motion alone was insufficient for upper arm rehabilitation, and horticultural motion alone was insufficient to induce continuous activity of the forearm.

  • 리소솜 acid phosphatase(LAP)를 포함하는 리소솜 산성 가수 분해 효소는 세포 내,외 성분의 분해에 중요한 기능을 수행하며, 유미 양서류의 다리 재생 과정에서 LAP의 효소 활성도는 탈분화시기에 특이적으로 증가하는 것으로 알려져 있다. 본 연구에서는 멕시코산 도룡뇽의 일종인 axolotl(Ambystoma mexicanum)의 다리 재생 가정에서 정상적인 다리 재생 조직과 retinoic acid (RA)가 처리된 다리 재생 조직에서 LAP의 분포 및 발현을 면역 화학적 방법으로 조사하였다. Axolotl의 다리 재생 조직에서 한국산 도룡뇽(Hynobius leechii)의 LAP에 대한 단일 항체를 이용한 면역 반응도는 줄 탈분화시기에 있는 wound epidermis와 미분화된 중배엽성 세포인 blastema 세포, 탈분화 상태의 근육과 연골 부위 세포에서 나타나는 것으로 조사되었다. 또한 LAP의 면역 반응도는 재생단게의 초기에 점차 증가하여 탈분화시기 동안 최대치에 도달하였으며, 재분화가 시작되면서 basal level 까지 서서히 감소하는 것으로 나타나\ulcorner. 유미 양서류의 다리 재생 과정에서 골격 패턴의 복제를 유발시키는 것으로 알려져 있는 RA 처리는 LAP의 면역 반응도를 강화시키는 것으로 나타나\ulcorner. 즉, RA가 처리된 다리 재생 조직에서 LAP의 면역 반응도는 정상적인 다리 재생 조직에서 보다 강하게 나타났으며, 면역 반응도가 나타나는 시기 또한 연장되는 것으로 조사되었다. 이와 같은 결과는 다리 재생 조직에서 RA 처리가 탈분화시기의 연장에 관여한다는 것을 시사하고 있다.

  • Objective : The purpose of this study was to investigate the effects of the Probody Massage Program on the physical characteristics, gross motor function and ROM (Range Of Motion) of children with cerebral palsy. Method : The subjects of this study were two children who have been diagnosed with first grade cerebral palsy that utilized T development support center located in B Metropolitan city for 8 weeks, twice a week, to carry out the Probody Massage Program for 30 minutes. Physiological reactions (height, weight, BMI, blood pressure (an index of inflammation), pulse rate) and large operating functions (sitting, crawling and the joints' range of motion as an angle of the shoulders' upper limb articulation) were measured pretest, after 4 weeks, and after 8 weeks. Results : The Probody Massage Program showed positive changes in physical characteristics (blood pressure, sitting, and crawling), gross motor function (upper limb shoulder movement), joint range of motion, height, body weight, metabolic activation and blood circulation of children with cerebral palsy. Conclusion : We believe making a practical impact on the growth and development, functional recovery of daily life, and improvement of quality of life of children with cerebral palsy by utilizing Probody Massage Program improves blood pressure (an index of inflammation), pulse, sitting, crawling, and the joints' range of motion as an angle of the shoulder joints' upper limb movement of children with cerebral palsy.
