[From the cellular pathology of Rudolf Virchow to modern cellular pathology. Results, problems].

Cellular pathology, one of the problems of natural science, is a part of theoretical bases on medicine. Created by R. Virchow in 1855, it has reached a new level, has acquired a new quality particularly in connection with the data obtained in the past 2 decades in investigations of the cell ultrastructure by special methods of electron microscopy. As a result, a hypothesis of diseases associated with organelles has arisen. Currently, mitochondrial and lysosomal diseases are gaining recognition. Examples of them are mitochondrial myopathies and accumulation diseases which can be not only congenital but be induced by lysosomotropic substances. "Organelle pathology" is closely associated with molecular pathology which is the most important basis of "organelle diseases".
