    Description / Table of Contents: Résumé Les coupes axiales d'épaule obtenues en IRM montrent une bande linéaire centrale à l'intérieur du m. supra-épineux, vide, qui ne semble pas représenter uniquement le tendon de ce muscle. En raison de l'importance du m. supraépineux dans les syndrômes douloureux de l'épaule, nous avons étudié l'architecture fibreuse de ce muscle, en comparant 30 imageries par résonnance magnétique nucléaire et 49 dissections cadavériques. Nous avons trouvé que le m. supra-épineux était composé de deux parties distinctes. La longueur moyenne de la partie ventrale est de 88 mm et celle de la partie dorsale de 106 mm. L'angle du tendon central qui est formé par les fibres des deux parties musculaires, fait 50° avec le plan frontal. Les deux parties musculaires agissent probablement différemment dans les mouvements du bras. Ces constatations semblent être importantes pour la physiopathologie des ruptures de la coiffe des rotateurs, qui sont principalement situées en avant, dans la partie ventrale du muscle et dans le tendon central excentrique.
    Notes: Summary Axial MR images of the shoulder joint reveal a central linear band within the supraspinatus muscle void of signal which seems not to represent the only tendon of this muscle. Due to the importance of the supraspinatus muscle for the painful impingement syndrome of the shoulder we studied the fibrous architecture of this muscle comparing 30 MR images and 49 cadaver dissections. We found the supraspinatus muscle to be composed of two distinct portions. The mean length of the ventral portion is 88 mm and of the dorsal portion 106 mm. The angle of the central tendon which is formed by fibers of both muscle portions relative to the frontal plane is 50°. Both muscle portions probably act differently in moving the arm. This finding seems to be important for the pathophysiology of rotator cuff tears which are mainly located anteriorly within the ventral muscle portion and the eccentric central tendon.

    Notes: Chronopotentiometry (CP) with enzyme electrodes is a new approach to overcome inherent problems of steady-state potentiometric processes. The developed procedure is presented on the example of a glucose oxidase (GOD) electrode. Electrochemically generated mediator helps to overcome traditional difficulties arising from poorly defined mixed potentials in the presence of oxygen during an analysis. Transition times are automatically evaluated by using computerized calculation programs. The technique can be used for determining substrate concentrations; moreover, it is particularly promising as an effective tool to study electrode processes with biochemical systems on an electrode surface.
