Nuclear bodies, averaging 0.8 to 1.2µ in diameter, were observed in various parenchymatous and interstitial cells of the calf. They were most prevalent and complex in structure in the parenchymatous cells of the adrenal cortex, and consisted of a fibrillar outer portion and a central or core area of varying size that was composed of electron-opaque particulate matter. These bodies, as far as the authors are aware, are of unknown significance.
