Cholesterol fatty liver. Morphological changes in the course of its development in rabbits.


Livers from 90 rabbits used in a factorial experiment relating cholesterol contents of various tissues to their serum cholesterol levels and duration of exposure were observed under light microscope. Livers from eight additional rabbits fed a 2% cholesterol diet for various periods up to 90 days were fixed in an aldehyde fixative containing 0.2% digitonin and observed under electron microscope. Digitonin-induced laminar and microtubular structures appeared five hours after cholesterol feeding. Fat vacuoles in both hepatocytes and Kupffer cells were first noted on the third day and increased in number and size to the 60th day but decreased on the 90th day. Adaptation of the liver to such excessive fat accumulation was evidenced by the gradual decrease of fat vacuoles and increase of binucleated cells.
