[Physiological and reparative regeneration of the mitochondria].
The ultrastructure of mitochondria of hepatocytes in normal and pathological conditions was studied. It was shown that the process of regeneration of the ultrastructure of swollen mitochondria with a lucent matrix up to the normal state was completed in hepatocytes of the rat and chick embryos within one day. It was established that one of the ways of intraorganoid regeneration of mitochondria in hepatocytes of chick embryos and of mice after injections of CCl4 twice a week for 5 months was clasmatosis of the destroyed mitochondria fragments and their removal through the partially disintegrated exterior membrane of mitochondria followed by the membrane restoration. The process of mitochondrial regeneration after clasmatosis of its fragments was shown to require two days in the chick embryo hepatocytes.
