PurposeBiceps labrum complex (BLC) lesions most commonly occur during sports activities in which the arm is frequently held in an overhead position. Among the available literature there are few histological studies about BLC. The purpose of this study was to demonstrate the anatomy of BLC and its attachment to the glenoid and to evaluate the results of our treatment for BLC lesions.Materials and MethodsAnatomical Study: Sixty shoulders from 30 cadavers were studied. We recorded the appearance of the glenoid labrum and the LHB. Then, we removed the glenoid process from the scapula leaving all of the capsular insertion intact. Sections were each cut along the cornal plane and along the sagittal plane at 200-300 p m thickness on a rotary milling saw, and then ground to a 20 p m thickness. The sections were stained with Cole's hematoxylin and eosin and examined via light and polarized light microscopy.Clinical Cases:Thirty shoulders of 29 patients with BLC lesions underwent arthroscopic debridement of the superior labrum.ResultsAnatomical Study: The LHB inserted directly to the superior glenoid and its attachment extended to the middle of the posterior glenoid. The LHB was firmly attached to the superior glenoid from the edge of the glenoid rim. The attachment was gradually loose toward the middle of the posterior glenoid. The LHB was attached to a large surface of the glenoid.Clinical Cases:All patients were able to return to competitive sports.DiscussionsBased on our anatomical study, the LHB has a larger attachment area on the glenoid than had been previously reported. Therefore, we believe debridement of the superior labrum for BLC lesions preserves the LHB functions.

Poor circulation is considered to be a cause of stiff shoulders, but there have been no studies on deep hemodynamics and the subjective estimation/palpation of stiff shoulders. We evaluated the relationship between deep hemodynamics and the degree of the subjective estimation/palpation of stiff shoulders by near-infrared spectrophotometry.<br>The subjects were 146 patients who visited our center and 23 healthy volunteers. Deep hemodynamics (tissue oxygen saturation: StO<sub>2</sub>, total hemoglobin concentration: total Hb) was measured in the scapular region of the bilateral shoulders using a deep hemodynamics measurement system (PSA-IIIN, Biomedical Science), and its relationship with the severity of the subjective estimation of stiff shoulders (5-grade rating) and that of palpation (4-grade rating) was evaluated. Deep hemodynamic values were affected by the body mass index (BMI) that is highly correlated with subcutaneous fat thickness. Therefore, analysis was performed in 70 patients and 8 healthy volunteers with BMI of 20-24 that does not affect hemodynamic values. Compared with the healthy volunteers, patients who reported marked shoulder stiffness showed a significant decrease in total Hb, and that who reported shoulder stiffness showed a significant decrease in StO<sub>2</sub>. On the other hand, compared with the healthy volunteers, patients with marked shoulder stiffness observed by palpation showed significant decreases in both StO<sub>2</sub> and total Hb; the decreases were more marked with more marked stiffness. These results suggested that deep hemodynamics is a diagnostic parameter of stiff shoulders.

To clarify the anatomy of the long thoracic nerve (LTN) and functional anatomy of 3 parts of the serratus anterior muscle (SA) from innervations and the shape of each fiber. We collected the 10 shoulders of 5 cadavers (3 males and 2 females,average age 82,4 years old). The upper, middle, and lower parts of SA were classified according to the Eisler's definition. We observed which components from C4, C5, C6, and C7 innervated each part of the SA. The upper part was mainly innervated by C5 fiber and also C4, C6, or C7 fibers connected to the parts in 8 of 10 shoulders. The long thoracic nerve consisted of C6 and 7 fibers innervated middle and lower parts. The cross section area of the upper part was wider than those of other parts, and the upper part ran in the direction of the anterior compared to that of the middle part. The upper part of SA may be worked as the center of the scapula in an up and downward rotation. Degenerative change or sprain of cervical spine and direct trauma to the medial scalenus muscle may have caused damage of LTN and then dysfunction of the SA.

日本の乳がん検診の受診率は極めて低く、さらに系統的ながん検診受診率対策が十分に行われていなかった。そこで、乳がん検診(マンモグラフィー検査)に関して、トランスセオレティカルモデル・計画的行動理論などの行動変容の理論と方法を用いて、行動変容モデルを作成し、モデル内の変数を用いた対象者セグメンテーションを行い、さらに異なるセグメント毎に心理的特性を考慮したメッセージを作成し、それらを送り分けるテイラード介入を実施し、コントロール群との実際の受診率の違いを無作為化比較試験によって検討した。641名の女性に対する調査の結果、目標意図・実行意図・がん脅威などの心理的変数からなる行動変容モデルが開発された。このモデルに基づいた対象者セグメンテーションが行われ、その妥当性が示された。3つのセグメント毎に開発されたメッセージを送り分けるテイラード介入を1,859名の女性を対象とした地域介入研究において実施した。その結果、テイラード介入群(19.9%)とコントロール群(5.8%、Odds ratio 95%信頼区間: 2.67–6.06)、さらにコントロール群と3つのセグメントの間で受診率に有意な違いがあることが明らかとなった。これらの研究から、行動変容モデルに従って対象者をセグメントに分け、そのセグメントがどのような心理的特性を持った人たちによって構成されているかを精緻に調べ、それに対応したメッセージとデザインを開発するという一連の方法は、効果的な行動変容を実現するためにはとても有効な方法であるのではないかと思われる。

[Purpose] The aim of this study was to determine the lower-limb muscle activities during muscle exercise using an on-the-bed muscle training device that utilizes the intermittent inflation of an oval rubber balloon placed against the sole. [Subjects and Methods] Ten healthy subjects were asked to adopt a semi-recumbent position with a flat oval chloridized polyvinyl balloon placed against the sole. The subjects were asked to extend both their legs when they felt the inflation of the balloon on their plantar surface. This exercise was defined as leg exercise against intermittent sole pressure stimulation (ExISPS). [Results] The root-mean-square (RMS)-EMG values of the vastus medialis during ExISPS in the semi-recumbent position were similar to those when standing up from 45-degree knee flexion and calf-raising. The RMS-EMG values of the biceps femoris showed no significant difference among these exercises. The RMS-EMG values of gastrocnemius medialis during ExISPS in the semi-recumbent position were higher than those when standing up from 45-degree knee flexion and standing up from a chair. [Conclusion] The findings of this study suggest that the muscle activities during ExISPS mimic or are greater than those required of the leg in daily life.

前報では, 超音波振動子を用いて, 骨伝導聴取を行うと, 超音波領域における骨伝導の可聴範囲は27dB前後であることを明らかにした。引き続き, 本報では, 骨導経由で与えられた超音波に対する聴覚特性を明らかにするために, 最初に超音波骨導音の音の高さ, 次に超音波骨導音によるマスキング, 更に気導音および骨導音による耳音響放射に関して実験的に検討している。これら骨導で与えられた超音波に対する諸特性の結果から, 超音波に応答する部位が蝸牛内に存在する可能性が示唆された。
