    Notes: [Auszug] Electron microscope observations showed that the following growth stages of such globules take place by means of peculiar particles which are characterized by a central clear zone and by a peripheral zone, that is, composed of dark granulations with a diameter of about 300 A. The particles arrange ...

    Notes: [Auszug] It was supposed therefore that in tumour cells there might also occasionally be found formations deriving from the aggregation of protein particles. I have now shown this to be the case. Fragments of Walker tumour of the Wistar albino rat were put for 5 hr. at room temperature (about 22 C.) in an ...

    Notes: [Auszug] In the oocytes of Patella coerulea, at the beginning of vitellogenesis, it is possible to observe a reticulum of filaments about 200 A. thick, which carry dark granulations about 300 A. in diameter (Fig. 1). Some reticular cavities show a dark content, which gradually increases with the growth of ...

    Notes: Riassunto Viene descritta mediante riprese microcinematografiche a tempo in cellule del tumore di Walker trattate con desossiribonucleasi la formazione graduale di globuli conseguenti alla aggregazione di ribosomi. Si Riritiene pertanto che venga confermata l'ipotesi che nella cellular tumorale esista una condizione particolare per cui, ad una anormale produzione di ribonucleoproteine, non segua la produzione di concreti prodotti di sintesi.

    Notes: Summary Observations with the electron microscope permitted us to ascertain that in molluscs and echinoderms oocytes and in malignat tumour cells, the nucleolini, already seen with the phonton microscope, correspond to the ‘clear fibrillar zones’. These present fibrils 40–60 Å thick, spread throughout a very clear matrix. All around these zones there are other closely thickened and interlacing fibrils.

    Notes: Riassunto I risultati delle ricerche condotte al microscopio fotonico sul nucleolo di cellule vegetali e animali, somatiche e germinali, normali e tumorali hanno permesso di affermare ancora una volta che le sole strutture presenti in esso sono i nucleolini. L'esistenza dei nucleolini è stata comprovata in vivo, come pure con varie tecniche in seguito ad osservazioni compiute con diversi tipi di microscopio. L'analisi statistica effettuata su ovociti diEchinus melo ha permesso di confermare che i nucleolini, che sono assenti nei nucleoli più piccoli, sono poi tanto più numerosi per quanto più elevato è il volume dei nucleoli più grandi.
