Electron-Microscopic Observations on the Finer Structure of Basophilic Granulocytes of Newt (Triturus pyrrhogaster)

Abstract
The basophilic granulocytes of newt blood were examined electron-microscopically with 2 fixation methods. With osmic acid fixation there was a crystal structure in the granules of the cell, but none with glutaraldehyde fixation. The granules had a homogenous or fine reticular content. It was concluded that the crystal structure in the granules of the basophilic granulocytes of newt blood is an artefact due to the osmium fixation.
