Coated vesicles in the rat adrenal glomerular zone after a low-sodium diet

Summary In rats subjected to a low-sodium diet, a great activity was observed of the coated vesicles at Golgi complex and cell surfaces of glomerular adrenal zone. These findings are related to the function of these organoids in the uptake and transport of necessary substances under stimulating conditions of the zone.

Ultrastructural study of binucleation in cells of the rat adrenal glomerular zone after a prolonged low-sodium diet

Summary Binucleate cells have been found in the glomerular zone of the adrenal cortex in rats subjected to low-sodium diets. By considering the various possibilities for their production, both the findings of nuclei in process of constriction and nuclei identical in form, confronted and smaller in size than those of neighbour cells, are in agreement with an amitotic nuclear division as the possible mechanism for the formation of these cells.     

Morphological modifications in the adrenal medulla after decortications of different extent in the left cerebral hemisphere

Résumé Les cobayes avec destruction du cortex frontal gauche présentent, 2 h après l'application d'un stress douloureux, une morphologie médullosurrénal nettement différente entre la glande du côté gauche et droit. La médullaire gauche ne montre pas de modifications appréciables. Au contraire, la médullaire droite montre des modifications qui indiquent une réponse au stress douloureux.     

Subcellular steroid distribution in the rat adrenal cortex

Summary The subcellular distribution of main steroids (pregnenolone, progesterone, corticosterone) and of cholesterol — this last after correction according to exchanges occuring during differential centrifugation — is presented in the rat adrenal cortex. The distribution patterns are not necessarly the same as established according to the localization of hydroxylating enzymes.This work was carried out under contract of the Ministère de la Politique Scientifique within the framework of the Association: Euratom, University of Brussels, University of Pise and also thanks to a grant of the Caisse Générale d'Epargne et de Retraite.     

Cycloheximide-induced ultrastructural changes in the adrenal cortex of the rat

Zusammenfassung Cycloheximid als allgemeiner Inhibitor der Proteinsynthese verursacht submikroskopische Veränderungen in der Nebennierenrinde der Ratte. Kompaktes Material und konzentrische Membranstrukturen im Zytoplasma von Zellen der Zona fasciculata finden sich um Mitochondrien und Lipidtropfen.     

Selective depletion of nor-adrenaline in the adrenal medulla of the rat after administration of reserpine (histochemical research)

Riassunto Con tecniche istochimiche è stata indagata l'azione della reserpina sul contenuto catecolico della midollare surrenale del ratto. Viene documentata una scarica pressochè selettiva di nor-adrenalina.     

Diurnal rhythm in the adrenal ascorbic acid concentration of the rat

Zusammenfassung Der tägliche Rhythmus des Ascorbinsäuregehalts in den Nebennieren von Ratten wurde untersucht. Es wurde beobachtet, dass der Ascorbinsäuregehalt um 16 h nachmittags am geringsten ist. Das absolute Gewicht der Nebennieren wiederum ist in der Nacht gegen 24 h am höchsten. Bei praktischen Arbeiten ist dieser Abfall im Ascorbinsäuregehalt der Nebennieren am Nachmittag zu berücksichtigen.
