Peripheral nerve trunks are not rigidly fixed to surrounding tissues along their course. They slide longitudinally in their beds over several millimeters with movements of the extremity. This concept of peripheral nerve excurisions helps to explain the pathophysiological events occurring in entrapment neuropathy, chronic nerve irritation and nerve compression. Although this is an important physiological phenomenon, this has not been examined precisely.We examined excursion of the normal sciatic nerves of 10 adult rabbits. The following were investigated:1) Percentage elongation of the sciatic nerve under nomal lower limb motion.2) Excursion between epineurium and gliding floor.3) Excursion between the funiculus.4) Morphological changes of the sciatic nerves under nomal lower limb motion.5) Microanatomical features of the peripheral nerves adapting movements of the extremity.The results were as follows:1) Total percentage elongation of the sciatic nerve was 5.8% in 0° flexion of the knee and 90° flexion of the hip joint. But near the knee joint, the maximum percentage was 9.2%.2) Excursion was found between the epineurium and gliding floor, and between the funiculus.3) It was proven that in the funiculus the nerve fibres have an undulating spiral pattern, which is, after its discoverer, called Fontana's bands. When the nerve was stretched in the course of movement, the undulation straightened out until it disappeared. Microanatomical view represents the wave-like alignment of the nerve fibres.By these features, peripheral nerves can accommodate limb motion.

The purpose of this study is to determine a target ROM (T-ROM) at 3 months after arthroscopic rotator cuff repair, by which patients can expect eventual full recovery. Subjects consist of 209 shoulders in 202 patients, including 116 males and 86 females with an average age of 61.5 years old, who underwent primary arthroscopic rotator cuff repair and were followed-up for a minimum of 2 years. There were 30 partial-thickness tears, 120 small to medium and 57 large to massive full-thickness tears. Anterior elevation (AE), external rotation at side (ER), and internal rotation (IR) ROM at 3 month after surgery (ROM-3M) were measured, and divided into five groups according to the values. The final ROM at 24 months after surgery was compared with each ROM-3M of these subgroups in order to determine the T-ROM. Then, according to the T-ROM, patients were also divided into two groups: less than the T-ROM (AE-, ER-, and IR-); and more than the T-ROM (AE+, ER+, and IR+), and average ROM in each group were compared with each other. The final ROM of AE was significantly better in the group of more than 120° than less than 120 degrees. Therefore, the T-ROM of AE was determined as 120°. Similarly, those of ER and IR were determined as 10° and L5 level. ROM at 6 and 9 months in the AE+ group was significantly better than those of the AE- group. Further, every ROM at 3 to 24 months in the ER+ group was significantly better than those of the ER- group. In conclusion, ROM at 3 months after surgery affects final shoulder function. Surgeons and therapists should pay attention to the T-ROM at 3 months after surgery described above in order to maximize patients's final shoulder function.

統合失調症の治療は、抗精神病薬による薬物療法が重要である。特に地域リハビリテーションでは薬物治療の維持の方策が重要である。今回、統合失調症の30歳女性がオランザピン口腔内崩壊錠の投与により長期の精神状態の安定化とともに就労が可能となった一例を報告した。これにより薬剤の形状の変化が社会復帰に貢献する可能性が示唆された。

Primary frozen shoulder is believed to be a self-limited disease. However, many patients complain of prolonged symptoms such as night pain and refractory stiffness. The purpose of this study is to estimate the efficacy of steroid injection to the glenohumeral joint for primary stiff shoulder associated with night pain. Subjects consisted of 115 consecutive patients, including 37 males and 72 females with an average age of 59.4 years old, who were diagnosed as having primary frozen shoulder at the shoulder clinic in our institute from May to November, 2009. Our treatment principles are as follows: we recommend patients who complain of night pain to keep their arm at rest and carry out trunk and scapular exercises, in addition to steroid injection to the glenohumeral joint once a week until the night pain subsides. Then, physiotherapy is initiated of the hand of therapists. Range of motion at the first visit and at the time when the night pain disappeared was evaluated, as well as that at the final follow-up which was 5.8 months on average.The mean forward flexion, external and internal rotation significantly improved when the night pain disappeared, which was 4.8 weeks on average, from 97.5, 9.2°, and S level to 117.5, 17.4°, and L4 level. The range of motion at the final follow-up was 144 degrees in flexion, 31 in external rotation, and L2 level in internal rotation.Steroid injection to the glenohumeral joint was effective for pain relief for patients with primary frozen shoulder associated with night pain. Removing inflammation at the glenohumeral joint is a key factor when treating such patients and this also enables patients to proceed with effective physiotherapy.

高齢者肺炎の特徴は,慢性的な基礎疾患を有すことが多く,潜在的臓器機能低下が肺炎の難治化および重症化の重要な因子である.また,これら高齢者肺炎で重要な位置を占めているのが誤嚥性肺炎であり,その病因には神経疾患,寝たきり状態など多くの病態が関与している.誤嚥性肺炎の発生には,嫌気性菌を含む複数の菌によることが多く,病態が複雑であることが多いため,抗菌療法においてはこれら高齢者の病態を十分に考慮したうえで適正な抗菌療法を行わなければならない.

Pyarthrosis of the knee was treated in 11 patients by arthroscopic lavage and debridement. There were 4 men and 7 women patients whose ages raged from 8 months to 80 years. Staphylococcus aureus was cultured in 5 knees. Four patients were caused by the injection of steroids. There were no recurrences. Arthroscopy can aid in establishing the diagnosis and implementing the appropriate treatment when a septic knee is suspected.

テトラリン体の精製における溶媒媒介転移を抑制するために, 転移に及ぼす晶析温度, 溶媒組成および撹拌速度の影響についてDSCを用いて検討を行った.転移の過程を経時的に追跡した結果, ある待ち時間を経たのちS字型の曲線を示しながら, 準安定形のA形結晶から安定結のB形結晶に転移した.転移過程を溶液濃度一定, すなわち過飽和度が一定の領域に対して成長速度式を用いて解析し, 総括転移速度定数, およびB形結晶が析出し始めるまでの待ち時間と種々な晶析条件との相関を求めた.この基礎実験結果に基づき, 500lスケールでパイロット実験を行った結果, 安定形のB形結晶を含まない準安定形のA形結晶のみを製造することができた.

19 patients with intramuscular hemangioma (IMH) in the extremity have been treated at our institution over the last 15 years. The average age was 20 years (range, 1 to 70 years).Involved sites were the lower extremity in 12 patients, and the upper extremity in 7. The mean follow-up period was 5.1 years (range, 0.5 to 15 years). Longstanding pain and swelling were common symptoms. Plain X-ray showed phlebolith in 10 patients. Magnetic resonance imaging, 13 patients, delineated the extent of the lesions, and revealed characteristic structures within the tumors. These two imaging modalities were informative for diagnosis and surgical treatment planning. Angiography and compued tomography were less valuable, although they also showed the lesions to some extent. Diagnosis of IMH was obtained preoperatively in 8 patients, however, the remaining 11 patients needed open biopsy. Extirpation of the tumors was performed in 17 patients, one of whom also received radiotherapy. Of the remaining two patients, one receieved only radiotherapy. The other, tumor was left untreated, because it was too extensive to be excised without significant morbidity. These two patients, had no major disability at the latest follow-up. Local recurrence occurred in 2 of the 17 surgically-treated patients. Complete extripation is needed for local control of the disease, but feasibility of the surgery depends on the tumor's location and size. Low dose radiotherapy may be a useful alternative, when the lesion is extensive, and the symptoms warrants.

This paper presents a three dimensional flutter analysis of slender webs under tension in cross flow. In the flutter analysis, Doublet-point method based on the unsteady lifting surface theory is used to calculate unsteady fluid force acting on the web surface. The equation of motion of the web under tension is derived by using the finite element method. Flutter velocity, frequency and mode are predicted through the root locus of the flutter determinant of the system with changing flow velocity. The theoretical results are compared to experimental results to confirm validity. Moreover, the local work done by the fluid force acting on the web surface is calculated, and instability mechanism is discussed. Lastly, unified empirical equation of flutter velocities for several parameters of webs is proposed.

イミダゾール体をエタノール水溶液中で, L-10-カンファースルホン酸と塩を形成させて光学分割する際に, 最少量の溶媒から両異性体の塩を結晶として充分析出させた後に, 少量の溶媒を徐々に添加して不要の異性体を優先的に溶解させる光学分割法を見い出した. 溶媒の添加方法にはよらず, 溶媒量により光学純度・収率が決定され, 溶解度から推算した値と一致した. 従来の冷却晶析法と比べ, 安定した収率 (50%) ・光学純度 (97%) で (+) イミダゾール体が得られ, 単位体積当たりの撹拌所要動力をスケールアップ因子として, 1,700l晶析槽で実験を行い, 1lスケールでの実験結果が再現できた.
