Ultrastructural study of the effects of amiodarone on the liver tissue was performed.
Rats were fed with amiodarone containing diet and were sacrificed at 1st, 3rd, 4th, 5th
and 8th weeks of experiment. Characteristic lisosomal inclusion bodies were appeared
from first week, which were more prominent and increased in size at the 5th and 8th
week of experiment. These inclusion bodies were found in hepatocytes, Kupffer cells,
bile duct epithelial cells and fibroblasts but most prominent in hepatocytes. The
lysosomal inclusion bodies could be divided into four types: those characterized by ¨ç
dense bodies with packed crystaloid contents, ¨è multilamellated bodies, ¨é irregular
shaped bodies with varying electron density and 4. dense bodies containing stacks of
fine membranous structures.
All types were found in all experimental groups. But the type 1 and 2 were
predominent at early stage, while type 3 and 4 were more prominent at later stage
According to these findings, the formation of the lysosmal inclusion body was a
characteristic change in derangement of phospholipid metabolism. And amiodarone could
induce disturbance of phospholipid metabolism in all kinds of cells in liver tissue.
