Morphological and morphometric studies of the liver with transplanted Lewis carcinoma were performed after polychemotherapy and correction with betulonic and [3-oxo-20(29)-lupene-28-oil]-3-aminopropionic acids and their methyl esters. It was demonstrated than betulonic and [3-oxo-20(29)-lupene-28-oil]-3-aminopropionic acids reduced the degree of degenerative changes and volume density of necrotic changes in hepatocytes after polychemotherapy. Methyl esters of these acids little changed the severity and spreading of destructive and necrotic changes in the liver caused by complex cytostatic therapy. It was also shown that all studied triterpenoids exhibited more pronounced antimetastatic effect (evaluated by the decrease in volume density of liver metastases) compared to polychemotherapy.
