Objectives : Although moxibustion is one of the most frequently used methods in oriental medicine, effect of moxibustion in myofiber regeneration and muscle fatigability is hardly studied. This study was researched to observe the effect of moxibustion in myofiber regeneration and muscle fatigability. Methods : We reviewed studies which contained moxibustion and published after 2000s in Pubmed. We also reviewed domestic studies in RISS, KISS and DBPIA, but only three studies were researched. Results : In myofiber regeneration, moxibuston has improved blood flow in muscle tissue and recover tissue injuries fast. Especially, moxibustion trigger an increse of HSP levels, which protect the cell against irreversible damage, apoptosis and death. Thus, that helps to stimulate myofiber regeneration. In many studies, as moxibustion stimulate PMRs and decrease fatigue substances, such as lactate acid and creatinine, so moxibustion is considered to be effective to recover and prevent muscle fatigability. Based on such effects, moxibustion is considered to have an effect on TPs, but have been hardly studied. Conclusions : Although Moxibution is considered to be effective in myofiber regeneration and muscle fatigability, futher study is needed.

In this paper, the researcher investigated whether strengthening the back muscles affects the quality of chest compressions during cardiopulmonary resuscitation by university students. A total of 50 students majoring in healthcare were included from September 2018 to November. The participants performed chest compressions during cardiopulmonary resuscitation (CPR) for 2 min after back muscle strength was measured. Then, after adequate rest, the participants repeated the back muscle strength measurements and chest compressions after taping the erector spinae muscle. The paired t-test was performed to analyze changes in chest compression quality after taping. As results, taping enhanced back muscle strength and positively affected the depth of chest compressions and the compression to recoil ratio. Taping also increased confidence and lowered fatigability during chest compressions, so the participants preferred being taped while performing chest compressions. Based on these results, taping could help emergency room medical personnel specialized in CPR to enhance the quality of CPR and relieve back pain and fatigability by strengthening the back muscles.

The purpose of this study was to evaluate the effect of concurrent and reciprocal isometric contraction and angle of ankle joint on fatigue of concentrically contracting contralateral dorsiflexor and plantar flexor. Seventeen able-bodied subjects participated in the study. Concurrent and reciprocal isometric contraction were performed under three different ankle joint angles (dorsiflexion, neutral position, plantar flexion). During concurrent or reciprocal isometric contraction. fatigue of concentrically contracting contralateral tibialis anterior, gastrocnemius, and soleus was investigated and compared. There was no interaction between different ankle joint angles and direction of isometric contraction (p<.05). No significant differences were found among three different ankle joint angles (p<.05). Contralateral muscle fatigability was lower in reciprocal isometric contraction than that in concurrent isometric contraction (p<.05). Therefore, the findings of this study suggest that reciprocal isometric contraction is more beneficial than concurrent isometric contraction inducing less fatigability during contralateral concentric contraction.

The characteristic features of myasthenia gravis, which are weakness of voluntary muscle and easy fatigability, result from defective neuromuscular transmission caused by an autoimmune response to acetylcholine receptor. Recently, we performed two cases of thymectomy for the treatment of myasthenia gravis, one was 50 year old man who had malignant thymoma and the other was 19 year old girl who had benign thymic hyperplasia. The former had long duration of symptoms, and showed poor postoperative result. The latter had short duration of symptoms, and showed complete remission. Herewith, we suggest that early thymectomy can give the clinical assets for myasthenia gravis. So we report these two experiences with review of literatures.

This report describes a rare, congenital hypertrophy of the left upper extremity that appeared after compressive bandage of right arm at the age of two. He is eighteen years old, and hypertrophy was aggravated for about 2 years since he started weight training exercise. Recently, skin turgor changed and he visited the Dermatology department. Skin biopsy revealed increased thickness of the dermis. On Orthopaedic examination, the left arm showed non­specific neuro-muscular changes other than easy fatigability a.nd increased skin consistency after exercise, compared to the right arm. The differences of circumference were 2.5 to 4cm according to the level of the upper limb. But the relative proportion of hypertrophy of the limb was balanced., On X-ray examination, bony changes were not shown. Through the MRI, we could find edematous changes of subcutaneous fatty tissue. Muscular structures showed unremarkable changes. Through the endurance test of both arms, we could find a decrease in endurance of the left upper arm musculatures. On histologic examination, infrequent focal necrosis and peri fascicular degeneration of the muscle fiber were present.

본 환자는 전신쇠약감 피로감, 고혈압과 혈청 potassium치가 저하되어 있고 혈청 Renin활성도가 감소되어 있으면서 Aldosterone억제 시험에도 억제가 되지 않았음을 볼 때 원발성 Aldosterone증을 의심할 수 있었다. 또 자세변화 시험에서 혈청 Renin활성도가 떨어져 있었고 자세변화에 따라 혈청 Aldosterone이 증가했으며 컴퓨터 단층촬영에서 별다른 병변이 뚜렷이 보이지 않음을 볼때 부신증식성 Aldosterone증으로 의심된다. 따라서 본 환자에게 spironolactone을 투여했고 이후 외래를 통해 추적검사 중이며 혈압 조절이 양호할 뿐 아니라, 불편을 느끼던 증상들도 호전이 되었음을 안 수 있었다. 끝으로 원발성 Aldosterone증에 대한 관심을 더 기울인다면 더 많은 증례가 발견될 것으로 사료되고, 본 저자들은 보다 많은 증례를 찾아 추후 증례보고및 추적검사할 예정이다.
