Summary
-
1.
In the epididymis of dogs the karyoplasm of the epithelial cells contains 3 different types of karyosomes which are regarded as being the fore-runners of the well known inclusion bodies.
-
2.
An extrusion of nuclear inclusion bodies into the endoplasmic reticulum is demonstrated.
-
3.
It is shown, that within the karyoplasm there are occasionally rather large vacuoles, crystalloids and fat droplets.
-
4.
The findings are indicative of a particularly vivid and complex nuclear metabolism.
