title: [Cytological analysis of the intact and regenerating liver of different strains of rats].
abstract: Comparative cytological studies were conducted on control and regenerating liver of two strains (August and Cotton) of rats, 2/3 of the liver was resected; 5 or 6 animals were sacrificed at each of the following postoperative periods: in 30 hours, 3, 8, 42 and 120 days. The number of binuclear cells, the size of mononuclear hepatocytes and their nuclei, the mitotic activity, and ploidity of hepatocytes were determined. The intact and regenerating liver of the August rats differed from the intact and regenerating liver of the Cotton rats by a number of cytological indices, excluding the mitotic activity. A conclusion was drawn that the observed interstrain differences in the cytological indices providing regeneration of the liver after resection in the August and Cotton rats depended on the genotype of the given strain.
