Demonstration von aus Blutgefäßen austretenden neutrophilen Granulozyten. Nacheinander werden Bewegungs- bzw. Wanderungsstadien von eosinophilen, neutrophilen, basophilen Granulozyten, Monozyten und Lymphozyten gezeigt. Ausgeprägte Granulakinetik. Verhalten von Spindelzellen.

The film documents the emigration of leucocytes from the blood vessels into adjacent tissues. One can watch the occurrence in the small mesenteric veins of the frog. In a cover glass preparation neutrophil, eosinophil and basophil granulocytes as well es monocytes and small and large lymphocytes are examined by phasecontrast microscopy. Finally the behaviour of spindle cells in vitro is shown.
