Comparative karyometric studies on small pseudolobuli and hepatomas in thioacetamide induced liver cirrhosis.
In the tumorous phase of TAA-induced cirrhosis of the liver comparative studies on the mitotic index, on the frequency of binucleated liver cells and on nuclear volume showed approximately similar values in the small pseudolobuli and in several hepatomas. Obviously "minimum deviation hepatomas" had developed. Decrease of ploidy characteristic for hepatomas was observed. In thioacetamide hepatomas the phenomenon of quadrupling of the cell nuclei due to dysfunctional nuclear edema occurred whereas the normal nuclei of liver cells can only double in volume in all phases of thioacetamide-intoxication. Particular karyometric aspects of the nuclear-nucleolar metabolism of hepatoma cells following thioacetamide intoxication are discussed.
