Fixation Method to Compress the Volar Plate Avulsion Fractures of the PIP Joint : A Case Study
Get PDF今回我々は中節骨基部掌側骨折（PIP関節掌側板付着部裂離骨折）に対して骨折部を圧迫し，PIP関節を最大屈曲した固定法を実施し，良好な治療経過が得られたため報告する．
症例は12才，男性．平成26年4月19日の学校の体育の時間にドッジボールで左中指を過伸展して受傷し，当日来院した．左中指に圧痛，運動時痛を共に認め，屈曲・伸展で若干の可動域制限を認めた．単純X線写真にて中節骨基部掌側の骨折を認めた．受傷後1週間はアルミ副子の先端を骨折部に当てPIP関節を最大屈曲させる圧迫固定を実施した．受傷1週後からは左中指の拘縮を防ぐために良肢位固定に切り替えた．受傷2週後からは脱着式の固定に変更し，入浴時などに左中指の自動屈伸運動を指導した．受傷3週後の単純X線写真では骨癒合は良好であり，左中指の可動域も受傷4週後には健側とほぼ同様に回復した．
固定管理に細心の注意を払わなければならないが，圧迫固定法は骨癒合を得ると同時に機能障害を残さない固定として中節骨基部掌側骨折に対して有用な固定法であると考えられる．We reported on good bone union for volar plate avulsion fractures of the PIP joint as a result of compressed the fracture and fixed by maximum bending the PIP joint. The patient was a 12-year-old male and had pain and limit of bending and stretching in his left third finger. X-rays showed he had a volar plate avulsion fractures of the PIP joint. We performed pressure immobilization for one week after the injury. 1 week after we switched to the good position in order to prevent contracture of the fingers. After two weeks we switched to fixed removable. Bone union was good in all three weeks. Range of motion of the finger was recovered after the injury four weeks.
Pressure immobilization is considered to be useful for the volar plate avulsion fractures of the PIP joint, but fixed management needs to be noted.departmental bulletin pape
Assessment of Relationship Between Static and Dynamic Balance Evaluation and Backward Two-Step Test
Get PDF【目的】後方2ステップテストの信頼性と静的・動的バランス評価との関係を検討することを目的とした．【対象と方法】健常男性19名に後方および前方2ステップテストを実施した．バランス評価は，重心動揺計から総軌跡長を算出し，さらにダイナミック平衡機能測定装置を使用し，前後方向への外乱刺激に対する反応時間を求めた．後方2ステップテストの信頼性を検討後，バランス評価との関連をスピアマンの順位相関係数にて算出した．【結果】信頼性は1回目の測定値を除外して算出した結果，ICC(1,1)は0.89であった．バランス評価との関連は後方への外乱刺激との間に軽度の関連がみられ，前方2ステップテストとは有意な相関が認められた．【考察】後方2ステップテストは不慣れな運動であり，信頼性の高い値を得るには1度練習を行ってから本測定することが推奨された．また，前方よりも後方への外乱との関連がみられることから，バランスを総合的に評価するためには，前方だけでなく後方2ステップテストの評価を実施していくことが重要と考えられた．[Purpose] The purpose of this study was assessment relationship between static and dynamic balance evaluation and Backward Two-Step Test. Furthermore, the present study was also examined the reliability of Backward Two-Step Test.
[Subjects and Methods] Subjects were 19 healthy males. The 19 males were measured Backward and Forward Two-Step Test. In addition, balance evaluation was measured by body sway and motor control test. Body sway was calculated total length, and motor control test was calculated latency that disturbance stimulation of backward and forward direction. After examined the reliability of the Backward Two-Step Test, was calculated the relationship between balance evaluation at Spearman's rank correlation coefficient.
[Results] Reliability results calculated by excluding the first measurement value, ICC (1,1) was 0.89. Exclude first measurement result, significant mild-related was seen in disturbance stimulation of backward between the Backward Two-Step Test and balance evaluation. In addition, a significant correlation was found with the Forward Two-Step Test.
[Discussion] Backward Two-Step Test was unfamiliar movement, in order to obtain reliable values, we have recommended to the measurement after the exercises once. In addition, Backward Two-Step Test was seen to be associated with the disturbance of backward than forward. For this reason, we were to comprehensively evaluate the balance, it was considered important to conduct the evaluation of the Backward Two-Step Test not only forward.departmental bulletin pape
Changing of the Body Composition in Weight Reduction for Bodybuilding Competition
Get PDF背景
ボディビル競技では体脂肪を最大限減少させ（除脂肪），除脂肪体重の多くを占める骨格筋が最も多い状態を作る（筋肥大）事が重要である．しかしその方法については不明な点が多い．
目的
ボディビルダーにおける試合までの長期調整（減量）期間における体重，身体組成の経時的変化を明らかにし，除脂肪，筋肥大の最適な方法を確立する事を目的とした．
方法
男子大学生ボディビルダー5名を対象とした．6ヶ月間1回／月，体重を測定し，インピーダンス法で体脂肪率，除脂肪体重，体脂肪量，体水分量を推定した．
結果
除脂肪体重以外の全ての項目は有意に減少した．体脂肪量の減少率は36.3±7.6％（-4.2±1.3kg）であり，除脂肪体重の2.7±1.2％（-1.8±1.0kg）と比較して有意に高かった．
結論
骨格筋を肥大させる目的を持ったボディビルダーの調整方法であれば除脂肪体重の減少を抑える事ができ，また体脂肪量の減少率が大きいため身体組成を著しく改善する事がわかった．レジスタンストレーニングには体重減少中の除脂肪体重損失を抑制する可能性ある事が示唆された．Background
Bodybuilders attempt to reduce body fat mass and increase skeletal muscle volume for bodybuilding competition. However the way is unclear.
Purpose
The present study is aim to obtain the beneficial information of the optimum way to reduce body fat and increase lean body mass (LBM) by revealing the changing body composition during weight reduction for bodybuilding contest.
Methods
Five male university bodybuilders were recruited. They tried resistance training 6 days a week. We measured body mass, %fat, LBM, fat mass and body water once a month during six months weight reduction for bodybuilding competition.
Results
All parameters were significantly decreased. The decrement of fat mass was 36.3±7.6％(-4.2±1.3kg). It was significantly higher than 2.7±1.2％of LBM(-1.8±1.0kg).
Discussion
Even if the way for weight reduction which attempts to gain maximum skeletal muscle mass by resistance training for bodybuilding competition, LBM doesn’t increase but remain. The way has ability to change the body composition remarkably because decrement of fat mass is very high and to prevent loosing LBM. We suggest that the person who tries to reduce their body mass should do resistance training to prevent loosing LBM.departmental bulletin pape

Physiological Reaction of Judo Athletes to Rope Training
Get PDF柔道の競技力強化の現場で行われている「ロープトレーニング」とは上肢と体幹を主に用いて局所筋持久力と全身持久力の向上を目的に行われるものである．この方法が柔道競技において普及しているのは柔道には上肢と体幹を多く用いるという競技特性があるためである．本研究ではロープトレーニングの生理学的反応を明らかにし，ロープトレーニングのトレーニング効果に関する知見を得ることを目的とした．
大学男子柔道部員10名を対象とし，ロープトレーニングをTabata protocolに模倣したロープトレーニングで行わせた．測定項目は酸素摂取量，血中乳酸濃度，心拍数とした．また，自転車ペダリング運動によって測定される仮定最大値（VO2max ，Lamax， HRmax）との相対値を算出した．
結果はVO2max に対してロープトレーニング中のpeakVO2は有意に低く，Lamax に対し，ロープトレーニング中のpeakLaは有意に高かった．peakHRはロープトレーニング中ほぼHRmaxに近い値で推移し，有意差はなかった．
上記によりロープトレーニングは解糖系に最大の負荷をかけるが，酸化機構には最大の半分程度の負荷しかけることができないということになる．これは，上肢などの局所筋における解糖系に大きな負荷がかかることで酸化機構への負荷が十分に高まる前にオールアウトしたことが原因であると考えられる．
今後は，ロープトレーニングで負荷をかけることができなかった酸化機構に最大負荷をかけることができるプロトコルを探索していくことが課題の1つである．Many Judo athletes do the workout waving the thick rope to improve their upper extremity and trunk muscular endurance and cardiopulmonary function. This way is popular with judo athletes because upper body works harder in judo competition. The purpose of this study is to clarify the physiological response of rope training.
The subjects were 10 male universities male judo athletes. We used the rope training the Tabata protocol with maximum effort. Measurement items during rope training were oxygen consumption (VO2), blood Lactate (La), and the heart rate (HR). To compare with maximum value and calculated relative values (%VO2, %La, %HR), we measured assumed maximum values by stationary bike pedaling exercise.
In rope training, peak VO2 were significantly lower for the assumed VO2max (26.5±4.5 vs 45.7±7.7 mil/kg/min, P＜0.01). PeakLa was significantly higher than that of assumed maximum value (7.8±0.8 vs 9.9±2.1 mmol/l, P＜0.05). PeakHR was close to HRmax, there was no significant difference (188.9±37.4 vs 200.4±1.0 b/min).
Rope training loaded to not enough aerobic energy pathway but glycolysis to enhance their capacity. For aerobic energy pathway, rope training loaded only half of maximum capacity. We think that rope training with maximum effort induces fatigue depended on the glycolysis of the upper extremity before aerobic energy pathway reaches to their maximum capacity. Therefor the rope training protocol used in present study is effective to enhance upper body muscular endurance. For judo athletes needed whole body endurance,
It is necessary to discover the rope training protocol to enhance cardiopulmonary function by maximum load for aerobic energy pathway.departmental bulletin pape
Myeloproliferative Neoplasms - Recent advances of its basic biology and the development of MPN-targeted therapies -
Get PDF骨髄増殖性腫瘍は造血幹細胞に由来するクローン性疾患であり、骨髄3系統の内の1系統以上の細胞の自律的増殖がある一方で、その増殖細胞の分化は障害されずに完全な成熟能を保つ極めて特異な腫瘍である。またその中の病型である真性赤血球増加症、本態性血小板血症、骨髄線維症は相互に移行するという特徴も有する。しかしその本態は長い間不明のままであったが、2005年に本疾患群の主要な病因遺伝子変異であるJAK2V617F変異が報告されて以来、本疾患群が血液学のトピックスとして大きな注目を集めて急速に研究が進み、その後JAK2 exon 12変異、MPLW515L/K変異、そしてついにはCALR遺伝子変異が発見された。これらの発症に関与する遺伝子変異以外にもエピジェネティックな因子の変異についても多くの報告がある。これら多くの遺伝子変異と病態との関連が明らかになるとともにそれぞれの病型の診断基準、予後予測に大きな進展が期待され、さらには明らかになった遺伝子変異を標的とした新規治療薬の開発が期待されている。Myeloproliferative neoplasms (MPN) are clonal disorders originated in hematopoietic stem cells and have unique characteristics showing simultaneous autonomous cell proliferation in some hematopoietic cell lineages and complete cell maturation without impaired differentiation. Moreover, some phenotypes of MPN, such as polycythemia vera, es-sential thrombocythemia and myelofibrosis transform to each other. The pathology and pathophysiology of MPN were unclear until 2005 when the major pathogenic gene mutation of JAK2V617F was discovered. After that, MPN emerged as noteworthy field in hematology and resulted in important findings of JAK2 exon 12 mutation, MPLW515L/K mutation CALR mutation, and mutations of many epigenetic genes. By these fruitful biological findings, important clinical analyses on the relationships between these gene mutations and clinical features progressed. These findings may con-tribute to making new diagnostic criteria and prognostic estimation and development of new targeted therapies.departmental bulletin pape
