    Description / Table of Contents: Résumé Une étude de la glande pinéale de la Taupe, animal vivant toujours dans une obscurité complète, a été entreprise selon la technique de fluorescence décrite par Falck et al. (1962). Une importante innervation catécholaminergique a été démontrée tandis que la fluorescence jaune — caractéristique des indoleamines-n'a pas été observée. Après omission du traitement par la formaldehyde, de très nombreuses cellules contenant du material autofluorescent (jaune-orange) furent observées. La nature et la fonction de ce material autofluorescent est discutée.
    Notes: Summary The pineal gland of the mole, a mammal which lives in permanent darkness, has been studied using fluorescence histochemistry. An extensive catecholaminergic innervation is demonstrated. A yellow formaldehyde-induced fluorescence, characteristic of indoleamines, was not observed. If formaldehyde vapour treatment was omitted in the procedure, numerous cells containing yellow-orange autofluorescent material could be shown. The nature and possible function of this material is discussed.

    Notes: Abstract The use of fluorescein dye for the study of ocular dynamics in ophthalmology is briefly reviewed. General principles for designing objective fluorophotometers for measuring the rate of change of fluorescein concentration are discussed. Details of the circuitry and performance of a new improved objective fluorophotometer using a quartz-halogen excitation source and a synchronous detector are presented. In a preliminary clinical trial the mean tear turnover rate for ten normal subjects was found to be 21±13% min−1.
