    Description / Table of Contents: Résumé La dissection de 48 pièces cadavériques, confrontée à des données opératoires, permet de rappeler la forme, la taille et la situation de cette glande chez l'adulte. La constitution de la loge thymique puis les rapports du thymus avec, en particulier, les vaisseaux du médiastin supérieur et la base du cou sont étudiés. Les positions respectives des glandes parathyroïdes inférieures et du thymus avec l'incidence de cette topographie dans la chirurgie de ces glandes, sont précisées. La vascularisation artérielle de la glande, encore très riche chez l'adulte est en faveur d'un organe fonctionnel dont l'involution physiologique est lente.
    Notes: Summary The dissection of. 48 cadaveric specimens has been compared with operative findings for a review of the shape, size and site of this gland in the adult. The structure of the thymic compartment and the relations of the thymus, particularly with the vessels of the superior mediastinum and the base of the neck, were studied. The relative positions of the inferior parathyroid glands and the thymus were identified, with respect to the influence of this topography on the surgery of these glands. The arterial suply to the thymus, which is still very abundant in the adult, presupposes a functional organ whose physiologic involution is slow.

    Notes: Summary Incisor pulp from the rabbit metabolises exogenous noradrenaline in concentrations between 0.12 and 1.2 μmol/l mainly to NMN. Effects of chronic sympathetic denervation indicated that in incisor pulp the NMN is extraneuronal in origin, and that DOPEG and DOMA formation, as well as a major part of the noradrenaline which accumulates in the tissue, are associated with the sympathetic nerves. NMN formation was unaffected by hydrocortisone 210 μmol/l, but was strongly inhibited by cocaine 30 μmol/l. These effects contrasted with those in the rabbit ear artery, where NMN formation was increased by cocaine 30 μmol/l and decreased by hydrocortisone 210 μmol/l. In COMT-inhibited denervated pulp, cocaine inhibited the accumulation of noradrenaline. Monoamine fluorescence histochemistry of pulp exposed to noradrenaline 50 μmol/l indicated that cocaine-sensitive uptake occurred in fibroblasts. It is concluded that O-methylation of noradrenaline in dental pulp involves prior uptake of the amine by a process resembling uptake, but which is distinguished from uptake1 by its extraneuronal location.
