Depletion and repletion of noradrenaline in adrenergic nerves of the rat after decaborane treatment

Zusammenfassung Mit Hilfe der Fluoreszenz-Technik werden die Veränderungen in sympathischen Fasern der Ratteniris nach Noradrenalin-Depletion durch Boron-Hydrid Decarboran (Dopa-Dekarboxylase-Hemmer) analysiert.

Zur Wirkung von Oxytocin auf einen autorhythmischen glatten Gefässmuskel

Summary The influence of oxytocine on the spontaneously contractile portal vein of the rat has been investigated. This octapeptide decreases the active tension and abolished it completely at a concentration of 5×10^–7g/ml. The effect is not caused by an adrenergic mechanism but by a direct action on the smooth muscle cell.     

Etude de l'hemocyanine d'un Crustacé décapodeCarcinus maenas Linné par dichroïsme circulaire naturel et dichroïsme circulaire magnétique

Summary The hemocyanin ofCarcinus maenas L. in the oxy, deoxy and apoforms is examined by CD and MCD. An interpretation of the results is given in relation to the problems raised by Cu–O² bond. The ration tyrosin/tryptophan is determined by treatment of spectra by computer.
