Summary

In chick embryos the best preservation of glycogen by conventional fixation methods was obtained withRossman's fixative. Although quenching methods give even better results, they are unsuitable for large pieces of tissues such as whole embryos. For this type of material a technique of intraventricular perfusion withRossman's fixative was devised. This method gave excellent preservation of glycogen and good cytological detail; most important of all, it made it possible to study the distribution of glycogen throughout a whole embryo in serial sections.

Zusammenfassung

Die Glykogenerhaltung in Hühnerembryonen wurde durch die üblichen Fixierungsmethoden mittelsRossmans Flüssigkeit erreicht. Obgleich man mit Kaltfixierung (quenching) noch bessere Resultate erhält, ist diese Methode für große Gewebsstücke (z. B. ganze Embryonen) unpassend. Für solches Material haben wir eine intra-ventrikuläre Perfusionstechnik unter Anwendung vonRossmans Gemisch entwickelt, welche sich ausgezeichnet für die Glykogenerhaltung eignet und zytologische Details gut zum Vorschein bringt. Am wichtigsten jedoch erachten wir, daß man auf diese Weise die wahre Glykogenverbreitung in ganzen Embryonen an Hand von Serienschnitten beurteilen kann.
