Immunohistochemical demonstration of corticotrophic cells concentrated in the rostral zone of the pars intermedia of the mouse hypophysis

Résumé La nature corticotrope des cellules constituant la partie rostrale de la pars intermedia de l'hypophyse de souris est établie par la microscopie électronique et la cytoimmunofluorescence. Cette zone réagit positivement avec les anticorps anti-ACTH et négativement avec les anticorps anti-MSH.     

Electron microscopic observations in the substantia nigra of mouse during reserpine administration

Zusammenfassung Reserpin bewirkte an den Zellen der Substantia nigra der Maus Verschwinden der Katecholamin-haltigen Granula und Anschwellen des endoplasmatischen Retikulums. Das Hauptmerkmal von normalen Kontrollzellen bildeten elektronenoptisch dichte Körper im Cytoplasma.     

Molecular aspects of 2 human urinary glycoproteins with histocompatibility antigen (HLA) serological activity]

Two serologically active urinary glycoproteins (HLA-A 9 and HLA-B 12) were isolated from urine provided by a patient suffering from tubular proteinuria. Their N-terminal sequences were automatically determined. The latter were identical with the sequence of another urinary glycoprotein (protein HC). The relationship between protein HC and the serological activity is discussed.     

Effect of orotic acid on liver glycogen of different animal species

Summary The effect of orotic acid on the liver glycogen content in the mice, frogs and catfish was studied. It was observed that the orotic acid significantly increases the glycogen content in the liver of mice and catfish as it does in rats. On the other hand it causes a fall of the glycogen level in frogs in experiments made both in autumn and spring. This effect was modified by amino acids administrated together with orotic acid.     

Über die Bindungsart der amidierten Reste derβ-Aminodicarbonsäuren in Eiweißstoffen

Summary Gliadin and chymotrypsinogen, respectively, were treated with alkaline sodium hypochlorite solution equivalent to the carbonamide groups present, and then hydrolysed by acid. The proteins treated with dilute alkaline solution have been assayed in control experiments for their content of N-terminal amino acids. The degradation products identified by paper chromatography seem to indicate that in chymotrypsinogen the amido groups of the amino dicarboxylic acids represent asparaginyl (Ia) and glutaminyl (Ib) residues. In gliadin, besides these residues, the presence of isoglutaminyl residues (IVb) also seems to be probable.
