[Changes of cell organelles in the developmental and aging process of heart and liver].
A systematic comparative investigation into the qualitative and quantitative ultrastructure of rat hearts and livers during postnatal development and ageing shows that there are similar and opposing changes within the hepatocytes and cardiocytes and their components. These processes are represented in male rats from birth up to the age of 27 months. The morphometrical examinations include cytoplasm, lipids, glycogen, mitochondria as well as primary and secondary lysosomes. The development of organs constitutes a dialectical unity of continuous and discontinuous processes within the cells characterized by degenerative as well as regenerative and synthetic processes.  This results in transformation of the structural organization of the cells during the whole life.
